HP HPE7-A01 Practice Test 45

Question 440

A stack's standby control member cannot take over after a failover drill because the new member has incompatible firmware. Which result would best establish that the correction succeeded?

  1. Client service continues through the backup gateway when either supported core is isolated.
  2. A single-member failure leaves all required server VLANs reachable.
  3. Storm counters stabilize and normal unicast forwarding returns without unintended blocked infrastructure links.
  4. All members join the stack and leadership failover completes without losing the remaining access members.

Explanation

Correct Answer

D:

This is an operational test of the required outcome rather than merely proof a setting exists. It checks that control-member version mismatch prevents stable participation in the intended logical stack no longer prevents the service.

Incorrect Answers

A:

This result may validate another network change, but it does not demonstrate recovery from the fault here: control-member version mismatch prevents stable participation in the intended logical stack.

B:

That explanation does not distinguish this option. “A single-member failure leaves all required server VLANs reachable” is an alternative action, but it does not by itself establish the outcome required in this case.

C:

That explanation does not distinguish this option. “Storm counters stabilize and normal unicast forwarding returns without unintended blocked infrastructure links” is an alternative action, but it does not by itself establish the outcome required in this case.

Question 441

A new finance printer is connected to an access port in VLAN 130, but the subnet gateway is an SVI in VLAN 120. Which result would best establish that the correction succeeded?

  1. Clients receive leases from approved servers without accepting rogue offers from user ports.
  2. Traffic follows the moved server's new port and no stale static entry remains.
  3. The printer obtains an address in the approved subnet and communicates via its intended SVI.
  4. The approved discovery application works through the relay while unrelated broadcasts remain separated.

Explanation

Correct Answer

C:

This is an operational test of the required outcome rather than merely proof a setting exists. It checks that access VLAN membership does not match the subnet selected for that endpoint no longer prevents the service.

Incorrect Answers

A:

This result may validate another network change, but it does not demonstrate recovery from the fault here: access VLAN membership does not match the subnet selected for that endpoint.

B:

That explanation does not distinguish this option. “Traffic follows the moved server's new port and no stale static entry remains” is an alternative action, but it does not by itself establish the outcome required in this case.

Question 442

An AP trunk has every VLAN enabled, allowing guest client traffic onto a restricted internal network. Which result would best establish that the correction succeeded?

  2. The correct instance root and forwarding topology appear for each mapped VLAN.
  3. Guest association still works but unapproved VLAN tags do not traverse the AP uplink.
  4. SNMPv3 exchanges reach the collector over IPv6 with expected credentials and source.

Explanation

Correct Answer

C:

This is an operational test of the required outcome rather than merely proof a setting exists. It checks that an over-permissive tagged trunk undermines the intended segmentation boundary no longer prevents the service.

Question 443

A CX switch has a healthy SVI but hosts cannot reach the directly connected gateway because the VLAN has no active member ports. Which result would best establish that the correction succeeded?

  1. Clients acquire correct leases through the approved relay path.
  2. Aggregate throughput improves with multiple distributed flows without packet reordering.
  3. Legitimate ARP exchanges succeed while forged gateway claims are rejected.
  4. The SVI responds to clients on active member ports and ARP resolves correctly.

Explanation

Correct Answer

D:

This is an operational test of the required outcome rather than merely proof a setting exists. It checks that an SVI may remain ineffective when its underlying VLAN has no usable access connectivity no longer prevents the service.

Incorrect Answers

A:

This result may validate another network change, but it does not demonstrate recovery from the fault here: an SVI may remain ineffective when its underlying VLAN has no usable access connectivity.

B:

That explanation does not distinguish this option. “Aggregate throughput improves with multiple distributed flows without packet reordering” is an alternative action, but it does not by itself establish the outcome required in this case.

C:

Question 444

An 802.1Q trunk carries VLAN 20 untagged on one end and tagged on the other, causing intermittent DHCP placement. Which result would best establish that the correction succeeded?

  2. The two groups access allowed services but cannot reach prohibited peers.
  3. SNMPv3 exchanges reach the collector over IPv6 with expected credentials and source.
  4. DHCP broadcasts remain within the intended VLAN and the link's tag behavior is symmetric.

Explanation

D:

This is an operational test of the required outcome rather than merely proof a setting exists. It checks that the two peers disagree about how untagged Ethernet frames map to a VLAN no longer prevents the service.

Incorrect Answers

A:

This result may validate another network change, but it does not demonstrate recovery from the fault here: the two peers disagree about how untagged Ethernet frames map to a VLAN.

Question 445

A file server connected by a LAG shows intermittent flows and one link is outside the port-channel. Which result would best establish that the correction succeeded?

  1. Guest association still works but unapproved VLAN tags do not traverse the AP uplink.
  2. Hosts resolve one intended gateway identity and maintain stable forwarding.
  3. Packets with valid bindings pass and forged source IPs from user ports are blocked.
  4. All members show compatible LACP state and the server maintains connectivity during a member failure.

Explanation

Correct Answer

D:

This is an operational test of the required outcome rather than merely proof a setting exists. It checks that one interface negotiates differently and is excluded from the logical forwarding group no longer prevents the service.
