HP HPE7-A08 Practice Test 32

Question 310

After implementing the approved change — Define appropriate DSCP/CoS trust boundaries and class-to-queue mapping — for this scenario: Voice traffic marked at a trusted phone should retain priority over bulk backups. Which observed result BEST verifies the outcome?

Measured control-plane and voice performance stay within acceptance thresholds
Packet markings and egress queues match the approved voice treatment
Interactive applications remain responsive while replication uses bounded bandwidth
The incident record contains timestamped interface and log evidence

Explanation

Correct Answer

Packet markings and egress queues match the approved voice treatment. This is the observable acceptance evidence for the decision to define appropriate DSCP/CoS trust boundaries and class-to-queue mapping. It demonstrates the principle that qoS classification and trust establish how traffic enters service classes.

Question 312

A risk review for the following wired-network case asks what should be avoided: Voice traffic marked at a trusted phone should retain priority over bulk backups. Which assumption creates the GREATEST implementation risk?

Raising every traffic class to strict priority and expecting isolation
Trusting all internet-sourced DSCP markings as equally authoritative
Assuming an unlimited upstream sender cannot congest a slower downstream link
Assuming separate VLAN broadcasts can communicate without routing

Explanation

Correct Answer

Trusting all internet-sourced DSCP markings as equally authoritative. That shortcut fails because qoS classification and trust establish how traffic enters service classes. Instead, the appropriate approach is to define appropriate DSCP/CoS trust boundaries and class-to-queue mapping.

Inspect queue-depth, drop counters and applied scheduling profiles
Inspect endpoint capabilities, MAC policy and allowed network destinations

Question 314

An implementation change is planned for: Voice traffic marked at a trusted phone should retain priority over bulk backups. Which preventive control BEST reduces unnecessary outage and security risk?

Load-test the exact profile before production
Document which ports may supply markings and test untrusted remarking
Set change thresholds and measure before-and-after throughput
Include explicit deny-and-allow acceptance tests before deployment

Explanation

Correct Answer

Document which ports may supply markings and test untrusted remarking. This safeguard is appropriate before the change to define appropriate DSCP/CoS trust boundaries and class-to-queue mapping; it reduces exposure to the mistake of trusting all internet-sourced DSCP markings as equally authoritative.

Question 315

A first repair attempt for this situation failed: Voice traffic marked at a trusted phone should retain priority over bulk backups. The review found the mistaken approach of trusting all internet-sourced DSCP markings as equally authoritative. Which targeted recovery action BEST restores the intended design?

Correct trust classification and remeasure packet delay
Rebalance queue weights or priorities and retest congestion
Correct the shaping rate and check that critical traffic no longer drops
Correct the relay destination and interface then renew a test lease

Explanation

Correct Answer

Correct trust classification and remeasure packet delay. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when packet markings and egress queues match the approved voice treatment.
