HP HPE7-A08 Practice Test 23

Question 220

At the Jasperfield research organization, a contractor endpoint marks all traffic as expedited forwarding and starves corporate voice during congestion. Which setting or practice should be reviewed in future?

  1. Review DSCP trust configurations after access role changes
  2. Review rate thresholds against measured normal guest demand
  3. Verify log retention and time synchronization after management changes
  4. Monitor control-plane drop and CPU statistics after policy updates

Explanation

Correct Answer

A:

After implementation, the team should review DSCP trust configurations after access role changes as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Jasperfield research organization.

Incorrect Answers

B:

Review rate thresholds against measured normal guest demand. This option operates on the following technical behavior: bursting guest traffic can consume resources needed for contracted business services. The source question instead asks about the control represented by: Review DSCP trust configurations after access role changes. That distinction must be resolved for the requested recurrence control.

C:

Verify log retention and time synchronization after management changes. This option operates on the following technical behavior: it requires the team to verify log retention and time synchronization after management changes. The source question instead asks about the control represented by: Review DSCP trust configurations after access role changes. That distinction must be resolved for the requested recurrence control.

D:

Monitor control-plane drop and CPU statistics after policy updates. This option operates on the following technical behavior: heavy unsolicited control traffic can contend with essential switch control functions. The source question instead asks about the control represented by: Review DSCP trust configurations after access role changes. That distinction must be resolved for the requested recurrence control.

Question 221

At the Westhaven customer service center, video downloads cause packet loss in voice calls because all traffic shares the same egress treatment. Which corrective action best meets the requirement?

  1. Inspect the classification rules DSCP mappings and per-queue counters at each relevant hop
  2. Correct matching LACP group configuration interface speed and peer negotiation on both ends
  3. Configure the supported helper or DHCP relay on the correct VLAN interface and confirm route reachability
  4. Implement supported classification and queue scheduling for voice without starving other traffic classes

Explanation

Correct Answer

D:

For the Westhaven customer service center, the appropriate correction is to implement supported classification and queue scheduling for voice without starving other traffic classes. The decisive reason is that a single congested best-effort queue does not protect latency-sensitive voice packets; acceptance evidence is that a synthetic load test meets voice delay loss and fairness thresholds.

Incorrect Answers

A:

Inspect the classification rules DSCP mappings and per-queue counters at each relevant hop. Its technical scope is explained by: a configured policy may not match traffic or may be rewritten further along the path. In this question, the decisive issue is: a single congested best-effort queue does not protect latency-sensitive voice packets. That is why the offered option is not the most direct implementation.

B:

The option states: Correct matching LACP group configuration interface speed and peer negotiation on both ends. The source describes its associated mechanism as: it requires the team to monitor LACP actor partner status after port changes. By contrast, the current situation is governed by: a single congested best-effort queue does not protect latency-sensitive voice packets. Choosing this alternative would leave the question’s specific implementation unresolved.

C:

Configure the supported helper or DHCP relay on the correct VLAN interface and confirm route reachability. This option is based on the following distinct technical behavior: layer 3 separation blocks local broadcast discovery without an approved relay path; a passing acceptance check would show that a test client receives the correct scope address and relay logs show the exchange. The present question instead depends on this mechanism: a single congested best-effort queue does not protect latency-sensitive voice packets. That difference matters for the requested implementation.

Question 222

At the Westhaven customer service center, video downloads cause packet loss in voice calls because all traffic shares the same egress treatment. Which underlying issue most directly explains this situation?

  1. Accepting arbitrary endpoint QoS markings can defeat the intended class priority scheme
  2. IGMP local group membership does not automatically create routed multicast forwarding across VLANs
  3. Periodic manual inspection can miss transient fault patterns that require device-local monitoring
  4. A single congested best-effort queue does not protect latency-sensitive voice packets

Explanation

Correct Answer

D:

The problem stems from the fact that a single congested best-effort queue does not protect latency-sensitive voice packets. A correct solution would implement supported classification and queue scheduling for voice without starving other traffic classes and check that a synthetic load test meets voice delay loss and fairness thresholds. This result addresses the stated challenge at the Westhaven customer service center.

Incorrect Answers

A:

Accepting arbitrary endpoint QoS markings can defeat the intended class priority scheme. The reported problem is governed by this different mechanism: a single congested best-effort queue does not protect latency-sensitive voice packets. The offered choice would not address that particular root-cause explanation directly.

B:

IGMP local group membership does not automatically create routed multicast forwarding across VLANs. The present question instead depends on this mechanism: a single congested best-effort queue does not protect latency-sensitive voice packets. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Periodic manual inspection can miss transient fault patterns that require device-local monitoring. The reported facts point to a different controlling condition: a single congested best-effort queue does not protect latency-sensitive voice packets. The alternative does not directly settle the required root-cause explanation.

Question 223

At the Westhaven customer service center, video downloads cause packet loss in voice calls because all traffic shares the same egress treatment. What evidence would justify considering this concern addressed?

  1. Sample test packets enter the intended queue and end-to-end counters agree
  2. The device appears online in the correct site and reports the expected managed configuration
  3. A synthetic load test meets voice delay loss and fairness thresholds
  4. A test host reaches the SVI address and permitted off subnet destinations

Explanation

Correct Answer

C:

At the Westhaven customer service center, evidence that a synthetic load test meets voice delay loss and fairness thresholds directly validates the correction, instead of testing a neighboring service.

Incorrect Answers

A:

Sample test packets enter the intended queue and end-to-end counters agree. This option is based on the following distinct technical behavior: a configured policy may not match traffic or may be rewritten further along the path. The present question instead depends on this mechanism: a single congested best-effort queue does not protect latency-sensitive voice packets. That difference matters for the requested acceptance evidence.

B:

it requires the team to review site inventory assignments whenever access closets move. The offered alternative applies that mechanism: The device appears online in the correct site and reports the expected managed configuration. The reported facts point to a different controlling condition: a single congested best-effort queue does not protect latency-sensitive voice packets. The alternative does not directly settle the required acceptance evidence.

D:

The option states: A test host reaches the SVI address and permitted off subnet destinations. The source describes its associated mechanism as: layer 2 VLAN existence does not by itself supply a routed gateway interface; a passing acceptance check would show that a test host reaches the SVI address and permitted off subnet destinations. By contrast, the current situation is governed by: a single congested best-effort queue does not protect latency-sensitive voice packets. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 224

At the Westhaven customer service center, video downloads cause packet loss in voice calls because all traffic shares the same egress treatment. How should the organization sustain the improvement?

  1. Review DSCP trust configurations after access role changes
  2. Monitor authentication failures and certificate lifecycle
  3. Audit queue drops and utilization during peak periods
  4. Monitor cloud management reachability through every WAN policy update

Explanation

Correct Answer

C:

The continuing safeguard is to audit queue drops and utilization during peak periods. It helps avoid the original condition: a single congested best-effort queue does not protect latency-sensitive voice packets. This result addresses the stated challenge at the Westhaven customer service center.

Incorrect Answers

A:

Review DSCP trust configurations after access role changes. The reported problem is governed by this different mechanism: a single congested best-effort queue does not protect latency-sensitive voice packets. The offered choice would not address that particular recurrence control directly.

B:

Monitor authentication failures and certificate lifecycle. Its technical scope is explained by: open access ports cannot distinguish authorized identities before granting network privileges. In this question, the decisive issue is: a single congested best-effort queue does not protect latency-sensitive voice packets. That is why the offered option is not the most direct recurrence control.

D:

Monitor cloud management reachability through every WAN policy update. This option is based on the following distinct technical behavior: it requires the team to monitor cloud management reachability through every WAN policy update. The present question instead depends on this mechanism: a single congested best-effort queue does not protect latency-sensitive voice packets. That difference matters for the requested recurrence control.

Question 225

At the Nortonwood university, an untrusted guest uplink overwhelms business traffic because ingress rates are unconstrained. Which approach best resolves the described issue?

  1. Implement supported classification and queue scheduling for voice without starving other traffic classes
  2. Align the intended MST region name revision and VLAN-to-instance mapping on participating switches
  3. Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role
  4. Apply supported ingress policing or rate limiting to the guest class using realistic thresholds

Explanation

Correct Answer

D:

Apply supported ingress policing or rate limiting to the guest class using realistic thresholds is the best response because bursting guest traffic can consume resources needed for contracted business services. A focused validation would establish that traffic generators show guest bursts are limited while approved office flows pass. This result addresses the stated challenge at the Nortonwood university.

Incorrect Answers

A:

Implement supported classification and queue scheduling for voice without starving other traffic classes. Its technical scope is explained by: a single congested best-effort queue does not protect latency-sensitive voice packets. In this question, the decisive issue is: bursting guest traffic can consume resources needed for contracted business services. That is why the offered option is not the most direct root-cause explanation.

B:

The option states: Align the intended MST region name revision and VLAN-to-instance mapping on participating switches. The source describes its associated mechanism as: mST region mismatches change topology interpretation and can select unexpected ports; a passing acceptance check would show that all intended switches report matching region configuration and stable root paths. By contrast, the current situation is governed by: bursting guest traffic can consume resources needed for contracted business services. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role. This option is based on the following distinct technical behavior: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The present question instead depends on this mechanism: bursting guest traffic can consume resources needed for contracted business services. That difference matters for the requested root-cause explanation.

Question 226

At the Nortonwood university, an untrusted guest uplink overwhelms business traffic because ingress rates are unconstrained. Which explanation best accounts for the concern?

  1. Bursting guest traffic can consume resources needed for contracted business services
  2. A single congested best-effort queue does not protect latency-sensitive voice packets
  3. IGMP local group membership does not automatically create routed multicast forwarding across VLANs
  4. Periodic manual inspection can miss transient fault patterns that require device-local monitoring

Explanation

Correct Answer

A:

The strongest explanation is that bursting guest traffic can consume resources needed for contracted business services. This accounts for the outcome and supports the action to apply supported ingress policing or rate limiting to the guest class using realistic thresholds. This result addresses the stated challenge at the Nortonwood university.

Incorrect Answers

B:

A single congested best-effort queue does not protect latency-sensitive voice packets. The present question instead depends on this mechanism: bursting guest traffic can consume resources needed for contracted business services. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: IGMP local group membership does not automatically create routed multicast forwarding across VLANs. The reported facts point to a different controlling condition: bursting guest traffic can consume resources needed for contracted business services. The alternative does not directly settle the required root-cause explanation.

D:

Periodic manual inspection can miss transient fault patterns that require device-local monitoring. In this question, the decisive issue is: bursting guest traffic can consume resources needed for contracted business services. That is why the offered option is not the most direct root-cause explanation.

Question 227

At the Nortonwood university, an untrusted guest uplink overwhelms business traffic because ingress rates are unconstrained. Which test result best shows the requirement is met?

  1. Traffic generators show guest bursts are limited while approved office flows pass
  2. Sample test packets enter the intended queue and end-to-end counters agree
  3. A scheduled synchronization preserves the approved setting and records its source
  4. A connected host preserves gateway reachability after either peer uplink fails

Explanation

Correct Answer

A:

At the Nortonwood university, evidence that traffic generators show guest bursts are limited while approved office flows pass directly validates the correction, instead of testing a neighboring service.

Incorrect Answers

B:

a configured policy may not match traffic or may be rewritten further along the path. The offered alternative applies that mechanism: Sample test packets enter the intended queue and end-to-end counters agree. The reported facts point to a different controlling condition: bursting guest traffic can consume resources needed for contracted business services. The alternative does not directly settle the required acceptance evidence.

C:

A scheduled synchronization preserves the approved setting and records its source. Its technical scope is explained by: group managed configurations can supersede direct local changes when ownership is not coordinated. In this question, the decisive issue is: bursting guest traffic can consume resources needed for contracted business services. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: A connected host preserves gateway reachability after either peer uplink fails. The source describes its associated mechanism as: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. By contrast, the current situation is governed by: bursting guest traffic can consume resources needed for contracted business services. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 228

At the Nortonwood university, an untrusted guest uplink overwhelms business traffic because ingress rates are unconstrained. Which ongoing control best prevents this issue from recurring?

  1. Review rate thresholds against measured normal guest demand
  2. Retest traffic markings after endpoint software updates
  3. Audit power source diversity and module status during site inspections
  4. Revalidate breakout compatibility after interface module or optics replacement

Explanation

Correct Answer

A:

The continuing safeguard is to review rate thresholds against measured normal guest demand. It helps avoid the original condition: bursting guest traffic can consume resources needed for contracted business services. This result addresses the stated challenge at the Nortonwood university.

Incorrect Answers

B:

Retest traffic markings after endpoint software updates. Its technical scope is explained by: a configured policy may not match traffic or may be rewritten further along the path. In this question, the decisive issue is: bursting guest traffic can consume resources needed for contracted business services. That is why the offered option is not the most direct recurrence control.

C:

The option states: Audit power source diversity and module status during site inspections. The source describes its associated mechanism as: it requires the team to audit power source diversity and module status during site inspections. By contrast, the current situation is governed by: bursting guest traffic can consume resources needed for contracted business services. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Revalidate breakout compatibility after interface module or optics replacement. This option is based on the following distinct technical behavior: a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. The present question instead depends on this mechanism: bursting guest traffic can consume resources needed for contracted business services. That difference matters for the requested recurrence control.

Question 229

At the Northport multisite corporate network, a team enables QoS but cannot explain why a critical application's packets still enter best-effort queues. Which implementation choice best addresses the situation?

  1. Implement supported classification and queue scheduling for voice without starving other traffic classes
  2. Inspect the classification rules DSCP mappings and per-queue counters at each relevant hop
  3. Configure supported IGMP snooping and membership handling for the multicast VLAN
  4. Check available PoE budget per port classification cabling and total supply against measured demand

Explanation

Correct Answer

B:

Inspect the classification rules DSCP mappings and per-queue counters at each relevant hop is the best response because a configured policy may not match traffic or may be rewritten further along the path. A focused validation would establish that sample test packets enter the intended queue and end-to-end counters agree. This result addresses the stated challenge at the Northport multisite corporate network.

Incorrect Answers

A:

Implement supported classification and queue scheduling for voice without starving other traffic classes. Its technical scope is explained by: a single congested best-effort queue does not protect latency-sensitive voice packets. In this question, the decisive issue is: a configured policy may not match traffic or may be rewritten further along the path. That is why the offered option is not the most direct implementation.

C:

Configure supported IGMP snooping and membership handling for the multicast VLAN. This option is based on the following distinct technical behavior: it requires the team to monitor multicast group tables and querier health during video changes. The present question instead depends on this mechanism: a configured policy may not match traffic or may be rewritten further along the path. That difference matters for the requested implementation.

D:

total chassis PoE consumption can exceed available power when endpoints start together. The offered alternative applies that mechanism: Check available PoE budget per port classification cabling and total supply against measured demand. The reported facts point to a different controlling condition: a configured policy may not match traffic or may be rewritten further along the path. The alternative does not directly settle the required implementation.

Question 230

At the Northport multisite corporate network, a team enables QoS but cannot explain why a critical application's packets still enter best-effort queues. What risk should the team identify as the primary issue?

  1. A single congested best-effort queue does not protect latency-sensitive voice packets
  2. A configured policy may not match traffic or may be rewritten further along the path
  3. Open access ports cannot distinguish authorized identities before granting network privileges
  4. A device without an EAP supplicant cannot complete the chosen port identity protocol

Explanation

Correct Answer

B:

This identifies the root issue: a configured policy may not match traffic or may be rewritten further along the path. At the Northport multisite corporate network, the team should therefore inspect the classification rules DSCP mappings and per-queue counters at each relevant hop.

Incorrect Answers

A:

The option states: A single congested best-effort queue does not protect latency-sensitive voice packets. By contrast, the current situation is governed by: a configured policy may not match traffic or may be rewritten further along the path. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

The offered alternative states: Open access ports cannot distinguish authorized identities before granting network privileges. The reported facts point to a different controlling condition: a configured policy may not match traffic or may be rewritten further along the path. The alternative does not directly settle the required root-cause explanation.

D:

A device without an EAP supplicant cannot complete the chosen port identity protocol. In this question, the decisive issue is: a configured policy may not match traffic or may be rewritten further along the path. That is why the offered option is not the most direct root-cause explanation.
