HP HPE7-A08 Practice Test 15

Question 140

A first repair attempt for this situation failed: Central displays a switch online but the desired site template does not deploy. The review found the mistaken approach of changing a local CLI setting while an authoritative template continues to overwrite it. Which targeted recovery action BEST restores the intended design?

Restore management routing and validate registration without widening firewall policy
Reassign the device to the correct group and reconcile delivered policy
Correct the template variable or group selection and reapply the intended config
Repair the stack adjacency and restore the approved member order

Explanation

Correct Answer

Correct the template variable or group selection and reapply the intended config. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the deployed running configuration matches the approved group settings.

Incorrect Answers

Question 141

An HPE Aruba Networking engineer faces this wired-network scenario: An on-site switch cannot reach Central after initial cabling. Which implementation action BEST addresses the requirement?

Assign the authorized switch to the correct HPE Aruba Networking Central group and validate its configuration source
Confirm group management mode, template variables and configuration push status
Integrate Central switch monitoring with the approved site and alert workflow
Validate management IP, DNS, time, outbound reachability and activation enrollment

Explanation

Correct Answer

Cloud onboarding depends on management reachability and valid registration. The targeted implementation is to validate management IP, DNS, time, outbound reachability and activation enrollment. The deployment succeeds when central reports a healthy managed connection for the expected device identity.

Question 142

After implementing the approved change — Validate management IP, DNS, time, outbound reachability and activation enrollment — for this scenario: An on-site switch cannot reach Central after initial cabling. Which observed result BEST verifies the outcome?

The deployed running configuration matches the approved group settings
Central reports a healthy managed connection for the expected device identity
The switch receives only the approved site policy and is managed in the expected group
The printer can reach necessary services but not employee-only networks

Explanation

Question 143

An HPE Aruba Networking design review examines: An on-site switch cannot reach Central after initial cabling. Which technical principle BEST explains the required approach?

Cloud management uses device identity and group-level configuration intent
Template-based provisioning needs correct variable and group context
Programmatic integration requires explicit authentication and least privilege
Cloud onboarding depends on management reachability and valid registration

Explanation

Correct Answer

Cloud onboarding depends on management reachability and valid registration. The case therefore calls for this specifically controlled action: validate management IP, DNS, time, outbound reachability and activation enrollment. The acceptance evidence is that central reports a healthy managed connection for the expected device identity.

Question 144

A risk review for the following wired-network case asks what should be avoided: An on-site switch cannot reach Central after initial cabling. Which assumption creates the GREATEST implementation risk?

Changing a local CLI setting while an authoritative template continues to overwrite it
Treating a lit Ethernet link as proof that cloud control is reachable
Assigning a branch switch to the core group to make the provisioning alert disappear
Trusting all internet-sourced DSCP markings as equally authoritative

Explanation

Correct Answer

Treating a lit Ethernet link as proof that cloud control is reachable. That shortcut fails because cloud onboarding depends on management reachability and valid registration. Instead, the appropriate approach is to validate management IP, DNS, time, outbound reachability and activation enrollment.

Question 145

Before changing switch configuration, an engineer investigates: An on-site switch cannot reach Central after initial cabling. Which FIRST check is most useful for isolating the cause?

Inspect serial inventory, licensing, group assignment and configuration mode
Inspect template render output, variables and pending push errors
Inspect the CLI prompt, running configuration and effective port status
Inspect management VRF, gateway, DNS and Central connection status

Explanation

Correct Answer

Inspect management VRF, gateway, DNS and Central connection status. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that cloud onboarding depends on management reachability and valid registration.

Run a network-connectivity checklist before shipping switches
Version template changes and use a staged test device
Define root priorities and test topology changes before production

Explanation

Correct Answer

Run a network-connectivity checklist before shipping switches. This safeguard is appropriate before the change to validate management IP, DNS, time, outbound reachability and activation enrollment; it reduces exposure to the mistake of treating a lit Ethernet link as proof that cloud control is reachable.

Question 148

An HPE Aruba Networking engineer faces this wired-network scenario: An engineer must add a supported VLAN and access port via local AOS-CX CLI. Which implementation action BEST addresses the requirement?

Persist the tested running configuration to startup configuration using the supported save method
Use configuration context to create the VLAN then apply the access VLAN to the intended interface
Use supported show commands and logs before modifying configuration
Design appropriate PIM-enabled multicast routing and compatible unicast reachability

Explanation

Correct Answer

CLI commands depend on the correct operational or configuration context. The targeted implementation is to use configuration context to create the VLAN then apply the access VLAN to the intended interface. The deployment succeeds when the interface running state carries the assigned VLAN to the test host.

Incorrect Answers
