HP HPE7-A08 Practice Test 42

Question 410

A risk review for the following wired-network case asks what should be avoided: A branch receives no DHCP leases following a routed VLAN migration. Which assumption creates the GREATEST implementation risk?

Assuming the uplink is healthy for all VLANs because VLAN 10 works
Adding an unrelated static IP route without verifying relay
Disabling all security policy to make one application reachable
Declaring OSPF healthy because ping to the neighbor IP succeeds

Explanation

Correct Answer

Adding an unrelated static IP route without verifying relay. That shortcut fails because dHCP forwarding must be explicitly configured across a routed boundary. Instead, the appropriate approach is to identify the absent or incorrect DHCP relay and server reachability.

Incorrect Answers

This misconception choice fits a different situation: A printer in VLAN 30 works locally but cannot reach a print server over an uplink. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to adding an unrelated static IP route without verifying relay.

This misconception choice fits a different situation: Only a restricted subnet is unreachable while all ordinary traffic passes. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to adding an unrelated static IP route without verifying relay.

This misconception choice fits a different situation: An OSPF neighbor remains down despite successful ICMP pings between peers. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to adding an unrelated static IP route without verifying relay.

Question 411

Before changing switch configuration, an engineer investigates: A branch receives no DHCP leases following a routed VLAN migration. Which FIRST check is most useful for isolating the cause?

Compare host IP settings, connected VLAN and gateway SVI
Inspect applied ACL rules, role decisions and traffic counters
Inspect LACP partner state, aggregator key and member operational state
Inspect DHCP relay target, active SVI and server path

Explanation

Correct Answer

Inspect DHCP relay target, active SVI and server path. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that dHCP forwarding must be explicitly configured across a routed boundary.

Incorrect Answers

This diagnostic choice fits a different situation: A user host has an IP address in the wrong subnet and cannot reach its gateway. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect DHCP relay target, active SVI and server path.

Question 412

An implementation change is planned for: A branch receives no DHCP leases following a routed VLAN migration. Which preventive control BEST reduces unnecessary outage and security risk?

Document matched peer configuration before connecting extra members
Include DHCP lease renewal in every routed VLAN cutover test
Use a standardized OSPF peer template with staged adjacency checks
Record optic and fiber validation at installation

Explanation

Correct Answer

Include DHCP lease renewal in every routed VLAN cutover test. This safeguard is appropriate before the change to identify the absent or incorrect DHCP relay and server reachability; it reduces exposure to the mistake of adding an unrelated static IP route without verifying relay.

Incorrect Answers

This prevention choice fits a different situation: A bundle reports suspended members while each individual port appears link-up. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to include DHCP lease renewal in every routed VLAN cutover test.

Question 413

A first repair attempt for this situation failed: A branch receives no DHCP leases following a routed VLAN migration. The review found the mistaken approach of adding an unrelated static IP route without verifying relay. Which targeted recovery action BEST restores the intended design?

Repair relay settings or server route and repeat lease acquisition
Correct the narrow rule or object reference without opening the entire network
Correct address assignment or DHCP scope and verify the local route
Correct the mismatched member parameters and re-form the LAG

Explanation

Correct Answer

Repair relay settings or server route and repeat lease acquisition. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when a relayed discovery reaches the authorized server and returns an address.

Incorrect Answers

This remediation choice fits a different situation: Only a restricted subnet is unreachable while all ordinary traffic passes. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to repair relay settings or server route and repeat lease acquisition.

Question 414

An HPE Aruba Networking engineer faces this wired-network scenario: Only a restricted subnet is unreachable while all ordinary traffic passes. Which implementation action BEST addresses the requirement?

Identify likely optic or fiber-layer faults using counters and optical diagnostics
Identify the relevant ACL or role policy drop on the forwarding path
Identify the host mask and gateway mismatch before changing switch routing
Identify a LACP peer or member consistency issue in the aggregate

Explanation

Correct Answer

Policy drops can mimic physical or routing outages for a specific flow. The targeted implementation is to identify the relevant ACL or role policy drop on the forwarding path. The deployment succeeds when allowed traffic continues and the denied traffic matches the documented policy.

Incorrect Answers

Question 415

After implementing the approved change — Identify the relevant ACL or role policy drop on the forwarding path — for this scenario: Only a restricted subnet is unreachable while all ordinary traffic passes. Which observed result BEST verifies the outcome?

OSPF neighbors reach the intended state and routes appear after repair
VSX peer health diagnoses the safe failover state under the observed fault
The port state changes when deliberately enabled and passes traffic
Allowed traffic continues and the denied traffic matches the documented policy

Explanation

Correct Answer

Allowed traffic continues and the denied traffic matches the documented policy. This is the observable acceptance evidence for the decision to identify the relevant ACL or role policy drop on the forwarding path. It demonstrates the principle that policy drops can mimic physical or routing outages for a specific flow.

Incorrect Answers

This verification choice fits a different situation: An OSPF neighbor remains down despite successful ICMP pings between peers. It does not resolve the stated failure mode. For this case, the decisive verification choice is to allowed traffic continues and the denied traffic matches the documented policy.

For this case, the decisive verification choice is to allowed traffic continues and the denied traffic matches the documented policy.

This verification choice fits a different situation: An access port shows administratively down even with a working patch cable. It does not resolve the stated failure mode. For this case, the decisive verification choice is to allowed traffic continues and the denied traffic matches the documented policy.

Question 416

An HPE Aruba Networking design review examines: Only a restricted subnet is unreachable while all ordinary traffic passes. Which technical principle BEST explains the required approach?

OSPF control-plane compatibility differs from simple IP reachability
Policy drops can mimic physical or routing outages for a specific flow
VSX peer split handling responds differently to ISL versus keepalive failures
CRC and physical alarms provide stronger link-health evidence than a lit LED

Explanation

Correct Answer

Policy drops can mimic physical or routing outages for a specific flow. The case therefore calls for this specifically controlled action: identify the relevant ACL or role policy drop on the forwarding path. The acceptance evidence is that allowed traffic continues and the denied traffic matches the documented policy.
