Cisco 300-715 Practice Test 5

Question 40

During a Cisco ISE postchange review, the following is observed: A new ISE virtual machine boots with fewer vCPUs and less RAM than the Cisco-supported appliance sizing profile while an operator assumes the installation ISO guarantees capacity. What should the team change before declaring this work complete?

  1. Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image.
  2. Use a hypervisor and installation method explicitly supported for the selected ISE release and appliance image.
  3. Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.
  4. Configure the supported zero-touch provisioning prerequisites including identity, DNS, network reachability, and trusted bootstrap data.

Explanation

Correct Answer

C:

Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources. This is appropriate because iSE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone. It should be verified by this evidence: The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds.

Incorrect Answers

A:

The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The repeat risk here is different: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. A directly relevant preventive control is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.

B:

Host contention clears and RADIUS response times return within the documented service target under the same traffic. The repeat risk here is different: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. A directly relevant preventive control is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.

D:

Review supported hypervisors and appliance sizing every time an ISE major release is adopted. The repeat risk here is different: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. A directly relevant preventive control is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.

Question 41

A security policy owner must resolve this specific case: A new ISE virtual machine boots with fewer vCPUs and less RAM than the Cisco-supported appliance sizing profile while an operator assumes the installation ISO guarantees capacity. What underlying Cisco ISE dependency explains this result?

  1. Virtual appliance compatibility is release and platform dependent; an OVA cannot be assumed portable across unrelated hypervisors.
  2. Authentication response performance depends on available compute and disk resources; high hypervisor contention can look like a policy outage.
  3. Zero-touch provisioning automates initial appliance setup only when the bootstrap environment can deliver the correct configuration to the intended appliance.
  4. ISE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone.

Explanation

Correct Answer

D:

ISE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone. This behavior directly governs the stated requirement. The recommended action is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources. The acceptance result is: The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds.

Incorrect Answers

A:

The offered option specifies “Virtual appliance compatibility is release and platform dependent; an OVA cannot be assumed portable across unrelated hypervisors”. The question requires “ISE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone”: the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. These are not equivalent responses to the stated requirement.

B:

Host contention clears and RADIUS response times return within the documented service target under the same traffic. The actual fault is governed by a different mechanism: the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The needed response is: ISE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone.

C:

Review supported hypervisors and appliance sizing every time an ISE major release is adopted. The actual fault is governed by a different mechanism: the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The needed response is: ISE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone.

Question 42

A network identity engineer receives the following requirement: A new ISE virtual machine boots with fewer vCPUs and less RAM than the Cisco-supported appliance sizing profile while an operator assumes the installation ISO guarantees capacity. Which measurable outcome proves the intended behavior?

  1. The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds.
  2. The deployed node passes Cisco-supported installation validation and starts the intended services on approved virtual infrastructure.
  3. Host contention clears and RADIUS response times return within the documented service target under the same traffic.
  4. One laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs.

Explanation

Correct Answer

A:

The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The required remediation is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources. It works because iSE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone.

Incorrect Answers

B:

The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The offered choice instead concerns a different principle: Review supported hypervisors and appliance sizing every time an ISE major release is adopted. Those technical conditions are not interchangeable.

C:

The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The offered choice instead concerns a different principle: Host contention clears and RADIUS response times return within the documented service target under the same traffic. Those technical conditions are not interchangeable.

D:

The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The offered choice instead concerns a different principle: one laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs. Those technical conditions are not interchangeable.

Question 43

An enterprise access-control incident describes: A new ISE virtual machine boots with fewer vCPUs and less RAM than the Cisco-supported appliance sizing profile while an operator assumes the installation ISO guarantees capacity. Which ongoing practice is most appropriate for this failure mode?

  1. Monitor virtualization resource contention as a separate failure domain from policy correctness.
  2. Reforecast MnT storage when adding network access devices or extending retention.
  3. Validate production health checks against the actual services used by switches and controllers.
  4. Validate VM resource reservations and version-specific sizing before deploying production PSNs.

Explanation

Correct Answer

D:

Validate VM resource reservations and version-specific sizing before deploying production PSNs. This control addresses recurrence of the observed failure. The governing behavior is: ISE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone. The ongoing acceptance check remains: The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds.

Incorrect Answers

A:

Host contention clears and RADIUS response times return within the documented service target under the same traffic. In the case being tested, the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The necessary acceptance evidence is: Validate VM resource reservations and version-specific sizing before deploying production PSNs.

B:

Monitoring node retains the defined reporting period without disk threshold alerts under a realistic log-rate trial. In the case being tested, the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The necessary acceptance evidence is: Validate VM resource reservations and version-specific sizing before deploying production PSNs.

C:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. In the case being tested, the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The necessary acceptance evidence is: Validate VM resource reservations and version-specific sizing before deploying production PSNs.

Question 44

A Cisco ISE operations team investigates this site issue: A monitoring VM fills its virtual disk because a small lab-sized volume was reused for enterprise authentication and accounting retention. Which response most directly corrects the described failure?

  1. Use a hypervisor and installation method explicitly supported for the selected ISE release and appliance image.
  2. Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image.
  3. Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.
  4. Restore a supported Monitoring persona deployment and the forwarding path for PSN operational logs.

Explanation

Correct Answer

B:

Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image. This is appropriate because monitoring storage requirements differ with event volume and retention; free capacity may be exhausted even when RADIUS authentication still succeeds. It should be verified by this evidence: Monitoring node retains the defined reporting period without disk threshold alerts under a realistic log-rate trial.

Incorrect Answers

A:

Host contention clears and RADIUS response times return within the documented service target under the same traffic. The repeat risk here is different: the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. A directly relevant preventive control is: Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image.

C:

A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The repeat risk here is different: the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. A directly relevant preventive control is: Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image.

D:

The Monitoring persona collects operational and reporting data, distinct from PSNs answering live AAA requests. The repeat risk here is different: the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. A directly relevant preventive control is: Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image.

Question 45

At a distributed Cisco ISE deployment, a security review finds: A monitoring VM fills its virtual disk because a small lab-sized volume was reused for enterprise authentication and accounting retention. Which statement best explains why the correct response works?

  1. Monitoring storage requirements differ with event volume and retention; free capacity may be exhausted even when RADIUS authentication still succeeds.
  2. Virtual appliance compatibility is release and platform dependent; an OVA cannot be assumed portable across unrelated hypervisors.
  3. ISE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone.
  4. A distributed ISE deployment has explicit primary configuration ownership; multiple unsynchronized primaries do not form a valid replicated policy set.

Explanation

Correct Answer

A:

Monitoring storage requirements differ with event volume and retention; free capacity may be exhausted even when RADIUS authentication still succeeds. This behavior directly governs the stated requirement. The recommended action is: Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image. The acceptance result is: Monitoring node retains the defined reporting period without disk threshold alerts under a realistic log-rate trial.

Question 47

An access-security change request states: A monitoring VM fills its virtual disk because a small lab-sized volume was reused for enterprise authentication and accounting retention. What should be incorporated into the change checklist?

  1. Review supported hypervisors and appliance sizing every time an ISE major release is adopted.
  2. Reforecast MnT storage when adding network access devices or extending retention.
  3. Monitor virtualization resource contention as a separate failure domain from policy correctness.
  4. Validate PSN redundancy and device-side timeout behavior during site commissioning.

Explanation

Correct Answer

The necessary acceptance evidence is: Reforecast MnT storage when adding network access devices or extending retention.

Question 48

An enterprise access-control incident describes: An ISE VM is migrated to an oversubscribed host and develops unpredictable RADIUS latency despite unchanged access policies. What is the most suitable solution within these constraints?

  1. Check supported hypervisor CPU, memory reservation, storage I/O, and resource contention before changing authentication rules.
  2. Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image.
  3. Use a hypervisor and installation method explicitly supported for the selected ISE release and appliance image.
  4. Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles.

Explanation

Correct Answer

A:

Check supported hypervisor CPU, memory reservation, storage I/O, and resource contention before changing authentication rules. This is appropriate because authentication response performance depends on available compute and disk resources; high hypervisor contention can look like a policy outage. It should be verified by this evidence: Host contention clears and RADIUS response times return within the documented service target under the same traffic.

Incorrect Answers

B:

The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds.

D:

Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The repeat risk here is different: Monitoring node retains the defined reporting period without disk threshold alerts under a realistic log-rate trial. A directly relevant preventive control is: Check supported hypervisor CPU, memory reservation, storage I/O, and resource contention before changing authentication rules.

Question 49

In a staged Cisco ISE network access rollout, the team observes: An ISE VM is migrated to an oversubscribed host and develops unpredictable RADIUS latency despite unchanged access policies. Which platform distinction is decisive in this scenario?

  1. Authentication response performance depends on available compute and disk resources; high hypervisor contention can look like a policy outage.
  2. Virtual appliance compatibility is release and platform dependent; an OVA cannot be assumed portable across unrelated hypervisors.
  3. Monitoring storage requirements differ with event volume and retention; free capacity may be exhausted even when RADIUS authentication still succeeds.
  4. Provisioning bootstrap and steady-state distributed policy management solve different lifecycle tasks.

Explanation
