HP HPE7-A08 Practice Test 10

Question 90

An implementation change is planned for: An enterprise needs secure onboarding for employee and guest wired ports. Which preventive control BEST reduces unnecessary outage and security risk?

Document trust boundaries and queue budgets before rollout
Pilot authentication and emergency access controls per endpoint type
Approve an authoritative IPAM worksheet before provisioning
Capture backups and dry-run the migration on representative links

Explanation

Correct Answer

Pilot authentication and emergency access controls per endpoint type. This safeguard is appropriate before the change to document identity source, port roles, authentication exceptions and enforcement requirements; it reduces exposure to the mistake of rolling out 802.1X to every edge port without a recovery allowance for special devices.

Incorrect Answers

This prevention choice fits a different situation: An operations center must guarantee voice traffic quality during campus congestion. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to pilot authentication and emergency access controls per endpoint type.

Question 91

A first repair attempt for this situation failed: An enterprise needs secure onboarding for employee and guest wired ports. The review found the mistaken approach of rolling out 802.1X to every edge port without a recovery allowance for special devices. Which targeted recovery action BEST restores the intended design?

Restore critical port reachability under an approved temporary exception and correct policy mapping
Add a supported power supply or reduce allocation before connecting all endpoints
Stop the change on a failed gate and restore the approved baseline
Remove the unintended loop and implement the supported redundancy arrangement

Explanation

Correct Answer

Restore critical port reachability under an approved temporary exception and correct policy mapping. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when employee and guest devices receive only their approved segment and policy.

Incorrect Answers

Question 92

An HPE Aruba Networking engineer faces this wired-network scenario: An operations center must guarantee voice traffic quality during campus congestion. Which implementation action BEST addresses the requirement?

Document identity source, port roles, authentication exceptions and enforcement requirements
Plan consistent QoS markings, trust boundaries and egress queue validation
Calculate PoE budget, switch uplinks and electrical redundancy as a single design package
Create a VLAN, subnet, gateway and routing handoff matrix before configuration

Explanation

Correct Answer

QoS is an end-to-end policy rather than a single interface checkbox. The targeted implementation is to plan consistent QoS markings, trust boundaries and egress queue validation. The deployment succeeds when voice quality remains within the approved jitter and loss threshold under test.

Question 93

After implementing the approved change — Plan consistent QoS markings, trust boundaries and egress queue validation — for this scenario: An operations center must guarantee voice traffic quality during campus congestion. Which observed result BEST verifies the outcome?

The stack forms reliably and member failures satisfy the agreed service objective
Test devices reach approved subnets through the intended gateways
Employee and guest devices receive only their approved segment and policy
Voice quality remains within the approved jitter and loss threshold under test

Explanation

Correct Answer

Voice quality remains within the approved jitter and loss threshold under test. This is the observable acceptance evidence for the decision to plan consistent QoS markings, trust boundaries and egress queue validation. It demonstrates the principle that qoS is an end-to-end policy rather than a single interface checkbox.

Incorrect Answers

Question 94

An HPE Aruba Networking design review examines: An operations center must guarantee voice traffic quality during campus congestion. Which technical principle BEST explains the required approach?

Implementation success includes traceability and change control
QoS is an end-to-end policy rather than a single interface checkbox
Network addressing and segmentation must be unambiguous across sites
Redundancy must be coordinated with L2 loop control and routing

Explanation

Correct Answer

QoS is an end-to-end policy rather than a single interface checkbox. The case therefore calls for this specifically controlled action: plan consistent QoS markings, trust boundaries and egress queue validation. The acceptance evidence is that voice quality remains within the approved jitter and loss threshold under test.

Incorrect Answers

Question 95

A risk review for the following wired-network case asks what should be avoided: An operations center must guarantee voice traffic quality during campus congestion. Which assumption creates the GREATEST implementation risk?

Counting copper ports but ignoring aggregate power limits
Rolling out 802.1X to every edge port without a recovery allowance for special devices
Assuming arbitrary uplink cables and ports can always form a VSF fabric
Trusting all incoming markings from untrusted endpoints

Explanation

Correct Answer

Trusting all incoming markings from untrusted endpoints. That shortcut fails because qoS is an end-to-end policy rather than a single interface checkbox. Instead, the appropriate approach is to plan consistent QoS markings, trust boundaries and egress queue validation.

Question 96

Before changing switch configuration, an engineer investigates: An operations center must guarantee voice traffic quality during campus congestion. Which FIRST check is most useful for isolating the cause?

Examine current topology, critical applications and backup configuration status
Measure traffic classes, marked flows and congestion points
Verify supported stack ports, hardware compatibility and link speed
Inspect loop topology, LAG design and failover requirements

Explanation

Correct Answer

Measure traffic classes, marked flows and congestion points. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that qoS is an end-to-end policy rather than a single interface checkbox.
