HP HPE7-A08 Practice Test 16

Question 150

An HPE Aruba Networking design review examines: An engineer must add a supported VLAN and access port via local AOS-CX CLI. Which technical principle BEST explains the required approach?

Operational inspection and configuration mutation have separate authorization needs
CLI commands depend on the correct operational or configuration context
Unsaved running state is not a durable replacement for startup configuration
Spanning-tree control is required when redundant bridged links can form loops

Explanation

Correct Answer

CLI commands depend on the correct operational or configuration context. The case therefore calls for this specifically controlled action: use configuration context to create the VLAN then apply the access VLAN to the intended interface. The acceptance evidence is that the interface running state carries the assigned VLAN to the test host.

Incorrect Answers

Question 151

A risk review for the following wired-network case asks what should be avoided: An engineer must add a supported VLAN and access port via local AOS-CX CLI. Which assumption creates the GREATEST implementation risk?

Assuming a successful command automatically persists after restart
Changing production settings while still gathering a baseline
Changing a local CLI setting while an authoritative template continues to overwrite it
Issuing interface configuration commands in operator mode

Explanation

Correct Answer

Issuing interface configuration commands in operator mode. That shortcut fails because cLI commands depend on the correct operational or configuration context. Instead, the appropriate approach is to use configuration context to create the VLAN then apply the access VLAN to the intended interface.

Question 152

Before changing switch configuration, an engineer investigates: An engineer must add a supported VLAN and access port via local AOS-CX CLI. Which FIRST check is most useful for isolating the cause?

Inspect the CLI prompt, running configuration and effective port status
Compare running and startup configuration before the maintenance test
Check ACL attachment, rule order, hit counts and test flows

Explanation

Correct Answer

Inspect the CLI prompt, running configuration and effective port status. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that cLI commands depend on the correct operational or configuration context.

Question 153

An implementation change is planned for: An engineer must add a supported VLAN and access port via local AOS-CX CLI. Which preventive control BEST reduces unnecessary outage and security risk?

Capture show-command evidence and scope before write operations
Document a save-and-verify step in every change checklist
Define root priorities and test topology changes before production
Make changes under an authorized administrator account and save the approved config

Explanation

Correct Answer

Make changes under an authorized administrator account and save the approved config. This safeguard is appropriate before the change to use configuration context to create the VLAN then apply the access VLAN to the intended interface; it reduces exposure to the mistake of issuing interface configuration commands in operator mode.

Question 154

A first repair attempt for this situation failed: An engineer must add a supported VLAN and access port via local AOS-CX CLI. The review found the mistaken approach of issuing interface configuration commands in operator mode. Which targeted recovery action BEST restores the intended design?

Save the validated configuration and repeat the nonproduction restart test
Reproduce the initial symptom from captured facts and apply only the validated fix
Re-enter the proper configuration context and correct the interface VLAN assignment
Align the VRRP group and restore correct virtual IP service

Explanation

Correct Answer

Re-enter the proper configuration context and correct the interface VLAN assignment. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the interface running state carries the assigned VLAN to the test host.

Question 155

An HPE Aruba Networking engineer faces this wired-network scenario: A switch works after a CLI session but loses a recent change on reboot. Which implementation action BEST addresses the requirement?

Use supported show commands and logs before modifying configuration
Use configuration context to create the VLAN then apply the access VLAN to the intended interface
Check cables, interface speeds, transceiver form factors and device negotiation compatibility
Persist the tested running configuration to startup configuration using the supported save method

Explanation
