HP HPE7-A08 Practice Test 11

Question 100

After implementing the approved change — Plan member numbering, supported stacking cables and standby selection — for this scenario: A campus will deploy one VSF stack across adjoining network closets. Which observed result BEST verifies the outcome?

Test devices reach approved subnets through the intended gateways
The stack forms reliably and member failures satisfy the agreed service objective
A single approved path failure leaves user traffic working as designed
Peer health and downstream paths meet acceptance criteria during isolated failures

Explanation

Correct Answer

The stack forms reliably and member failures satisfy the agreed service objective. This is the observable acceptance evidence for the decision to plan member numbering, supported stacking cables and standby selection. It demonstrates the principle that vSF planning includes topology, conductor and failover behavior.

Incorrect Answers

This verification choice fits a different situation: An enterprise consolidates multiple department VLANs onto routed distribution switches. It does not resolve the stated failure mode. For this case, the decisive verification choice is to the stack forms reliably and member failures satisfy the agreed service objective.

For this case, the decisive verification choice is to the stack forms reliably and member failures satisfy the agreed service objective.

Question 101

An HPE Aruba Networking design review examines: A campus will deploy one VSF stack across adjoining network closets. Which technical principle BEST explains the required approach?

Implementation success includes traceability and change control
Network addressing and segmentation must be unambiguous across sites
Operational cutovers require reversible checkpoints and dependency order
VSF planning includes topology, conductor and failover behavior

Explanation

Correct Answer

VSF planning includes topology, conductor and failover behavior. The case therefore calls for this specifically controlled action: plan member numbering, supported stacking cables and standby selection. The acceptance evidence is that the stack forms reliably and member failures satisfy the agreed service objective.

Incorrect Answers

Question 102

A risk review for the following wired-network case asks what should be avoided: A campus will deploy one VSF stack across adjoining network closets. Which assumption creates the GREATEST implementation risk?

Planning uplinks without validating optical reach and connector type
Assuming arbitrary uplink cables and ports can always form a VSF fabric
Adding uncoordinated parallel links to the same broadcast domain
Moving all uplinks simultaneously without a tested rollback path

Explanation

Correct Answer

Assuming arbitrary uplink cables and ports can always form a VSF fabric. That shortcut fails because vSF planning includes topology, conductor and failover behavior. Instead, the appropriate approach is to plan member numbering, supported stacking cables and standby selection.

Incorrect Answers

Question 103

Before changing switch configuration, an engineer investigates: A campus will deploy one VSF stack across adjoining network closets. Which FIRST check is most useful for isolating the cause?

Inspect the fiber plant, distance estimates, switch optics support and patch schedule
Collect endpoint PoE classes and power-supply ratings
List endpoint classes, RADIUS reachability and allowed fallback behavior
Verify supported stack ports, hardware compatibility and link speed

Explanation

Correct Answer

Verify supported stack ports, hardware compatibility and link speed. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that vSF planning includes topology, conductor and failover behavior.

Incorrect Answers

Question 104

An implementation change is planned for: A campus will deploy one VSF stack across adjoining network closets. Which preventive control BEST reduces unnecessary outage and security risk?

Include loss-of-link testing for each individual path
Perform staged member-add and conductor-failover rehearsal
Include ISL failure and keepalive-loss test cases in the plan
Document trust boundaries and queue budgets before rollout

Explanation

Correct Answer

Perform staged member-add and conductor-failover rehearsal. This safeguard is appropriate before the change to plan member numbering, supported stacking cables and standby selection; it reduces exposure to the mistake of assuming arbitrary uplink cables and ports can always form a VSF fabric.

Incorrect Answers

This prevention choice fits a different situation: A large office requires two redundant aggregation paths to protect against a single link failure. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to perform staged member-add and conductor-failover rehearsal.

Question 105

A first repair attempt for this situation failed: A campus will deploy one VSF stack across adjoining network closets. The review found the mistaken approach of assuming arbitrary uplink cables and ports can always form a VSF fabric. Which targeted recovery action BEST restores the intended design?

Rebuild the VSF topology using supported ports and member identities
Stop the change on a failed gate and restore the approved baseline
Replace mismatched optics and revise the circuit schedule before cutover
Restore the verified previous path and replay only the approved migration steps

Explanation

Correct Answer

Rebuild the VSF topology using supported ports and member identities. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the stack forms reliably and member failures satisfy the agreed service objective.

Incorrect Answers

For this case, the decisive remediation choice is to rebuild the VSF topology using supported ports and member identities.

Question 106

An HPE Aruba Networking engineer faces this wired-network scenario: A campus uses a VSX core pair plus downstream dual-homed distribution links. Which implementation action BEST addresses the requirement?

Create a VLAN, subnet, gateway and routing handoff matrix before configuration
Define VSX roles, ISL, keepalive and VSX LAG implementation sequence
Create a site-by-site implementation plan mapping topology, interfaces, optics and dependencies
Design redundant uplink paths and specify control-plane loop-prevention or multi-chassis behavior

Explanation

Correct Answer

VSX availability depends on independent peer communication and consistent LAG design. The targeted implementation is to define VSX roles, ISL, keepalive and VSX LAG implementation sequence. The deployment succeeds when peer health and downstream paths meet acceptance criteria during isolated failures.

Incorrect Answers

After implementing the approved change — Define VSX roles, ISL, keepalive and VSX LAG implementation sequence — for this scenario: A campus uses a VSX core pair plus downstream dual-homed distribution links. Which observed result BEST verifies the outcome?

Voice quality remains within the approved jitter and loss threshold under test
Test devices reach approved subnets through the intended gateways
A single approved path failure leaves user traffic working as designed
