HP HPE7-A08 Practice Test 27

Question 260

An HPE Aruba Networking engineer faces this wired-network scenario: A client VLAN needs addresses from a DHCP server in another routed subnet. Which implementation action BEST addresses the requirement?

Validate platform-supported overlay functions and configure required underlay reachability first
Configure DHCP relay on the appropriate routed interface toward the authorized server
Install a supported route or routing protocol in the correct VRF without leaking unauthorized networks
Configure a supported VRRP group with consistent virtual gateway and priorities

Explanation

Correct Answer

DHCP broadcast discovery does not inherently traverse routers without relay. The targeted implementation is to configure DHCP relay on the appropriate routed interface toward the authorized server. The deployment succeeds when client requests reach the server and return leases with correct subnet settings.

Incorrect Answers

This implementation choice fits a different situation: A data center design requires VXLAN connectivity between routed transport endpoints. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to configure DHCP relay on the appropriate routed interface toward the authorized server.

This implementation choice fits a different situation: An isolated branch VRF lacks a route to the headquarters application. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to configure DHCP relay on the appropriate routed interface toward the authorized server.

This implementation choice fits a different situation: Two gateway switches should provide first-hop redundancy for one user VLAN. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to configure DHCP relay on the appropriate routed interface toward the authorized server.

Question 261

After implementing the approved change — Configure DHCP relay on the appropriate routed interface toward the authorized server — for this scenario: A client VLAN needs addresses from a DHCP server in another routed subnet. Which observed result BEST verifies the outcome?

The test overlay forwards intended tenant traffic without unintended leakage
Neighbor state reaches the expected adjacency and required routes appear
Clients retain virtual-gateway reachability after an approved master failure
Client requests reach the server and return leases with correct subnet settings

Explanation

Correct Answer

Client requests reach the server and return leases with correct subnet settings. This is the observable acceptance evidence for the decision to configure DHCP relay on the appropriate routed interface toward the authorized server. It demonstrates the principle that dHCP broadcast discovery does not inherently traverse routers without relay.

Question 262

An HPE Aruba Networking design review examines: A client VLAN needs addresses from a DHCP server in another routed subnet. Which technical principle BEST explains the required approach?

Layer 3 routing requires valid interfaces and reachable reverse paths
DHCP broadcast discovery does not inherently traverse routers without relay
OSPF neighbor formation requires consistent area and interface parameters
Overlay tunnels require a working routed underlay and compatible control plane

Explanation

Correct Answer

DHCP broadcast discovery does not inherently traverse routers without relay. The case therefore calls for this specifically controlled action: configure DHCP relay on the appropriate routed interface toward the authorized server. The acceptance evidence is that client requests reach the server and return leases with correct subnet settings.

Incorrect Answers

Question 263

A risk review for the following wired-network case asks what should be avoided: A client VLAN needs addresses from a DHCP server in another routed subnet. Which assumption creates the GREATEST implementation risk?

Giving the peers unrelated virtual IP addresses and expecting automatic failover
Placing a route in the default VRF and assuming all VRFs inherit it
Assuming separate VLAN broadcasts can communicate without routing
Adding an ordinary static route and expecting it to forward DHCP broadcasts

Explanation

Correct Answer

Adding an ordinary static route and expecting it to forward DHCP broadcasts. That shortcut fails because dHCP broadcast discovery does not inherently traverse routers without relay. Instead, the appropriate approach is to configure DHCP relay on the appropriate routed interface toward the authorized server.

Question 264

Before changing switch configuration, an engineer investigates: A client VLAN needs addresses from a DHCP server in another routed subnet. Which FIRST check is most useful for isolating the cause?

Inspect underlay routing, tunnel endpoint and VNI mappings
Check relay configuration, server reachability and packet counters
Inspect SVI operational state, IP subnets and route lookup
Inspect VRRP state, priorities and client default-gateway settings

Explanation

Correct Answer

Check relay configuration, server reachability and packet counters. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that dHCP broadcast discovery does not inherently traverse routers without relay.

Question 265

An implementation change is planned for: A client VLAN needs addresses from a DHCP server in another routed subnet. Which preventive control BEST reduces unnecessary outage and security risk?

Document supported model, software and route-target expectations
Stage routing peers with a known-good interface and timer baseline
Perform master-down testing after checking gateway MAC behavior
Verify relay paths and authorized servers during site acceptance

Explanation

Correct Answer

Verify relay paths and authorized servers during site acceptance. This safeguard is appropriate before the change to configure DHCP relay on the appropriate routed interface toward the authorized server; it reduces exposure to the mistake of adding an ordinary static route and expecting it to forward DHCP broadcasts.

Incorrect Answers

Question 266

A first repair attempt for this situation failed: A client VLAN needs addresses from a DHCP server in another routed subnet. The review found the mistaken approach of adding an ordinary static route and expecting it to forward DHCP broadcasts. Which targeted recovery action BEST restores the intended design?

Correct the route within the intended VRF and test permitted paths
Restore SVI addressing and route visibility then repeat host tests
Correct the relay destination and interface then renew a test lease
Correct the mismatched OSPF parameter and clear only necessary neighbor state

Explanation

Correct Answer

Correct the relay destination and interface then renew a test lease. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when client requests reach the server and return leases with correct subnet settings.

Question 267

An HPE Aruba Networking engineer faces this wired-network scenario: Multicast video receivers report excess streams on their access VLAN. Which implementation action BEST addresses the requirement?

Design appropriate PIM-enabled multicast routing and compatible unicast reachability
Assign the authorized switch to the correct HPE Aruba Networking Central group and validate its configuration source
Configure scheduler and queue-profile weights appropriate to critical traffic classes
Use supported IGMP snooping to learn interested receiver ports and validate querier behavior

Explanation

Correct Answer

IGMP snooping limits Layer 2 multicast flooding based on membership. The targeted implementation is to use supported IGMP snooping to learn interested receiver ports and validate querier behavior. The deployment succeeds when subscribed receivers get the intended multicast while unrelated ports avoid unnecessary flooding.

Incorrect Answers

For this case, the decisive principle choice is to iGMP snooping limits Layer 2 multicast flooding based on membership.

Question 270

A risk review for the following wired-network case asks what should be avoided: Multicast video receivers report excess streams on their access VLAN. Which assumption creates the GREATEST implementation risk?

Assuming IGMP snooping alone routes multicast between IP subnets
Disabling all multicast without checking subscribed receivers
