Question 120

The HPE AOS-CX switching case is: A recovery procedure depends on an SSH jump host that resides behind the very campus link likely to fail. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)

  1. Design link aggregation with compatible member speed, LACP state, switch support and upstream logical-system boundaries.
  2. Plan resilient management addressing, VRF separation, DNS, time, AAA and emergency access before connecting production uplinks.
  3. A traceability matrix connects each requirement to an implementation decision, verification command or user-facing test.
  4. Identify client VLAN boundaries, relay targets, routing and DHCP protection controls so hosts obtain addresses from authorized servers.
  5. The NOC reaches the switch through its approved management path during a simulated production uplink failure.

Explanation

Correct Answers

B:

The targeted correction for A recovery procedure depends on an SSH jump host that resides behind the very campus link likely to fail is: Plan resilient management addressing, VRF separation, DNS, time, AAA and emergency access before connecting production uplinks. It reduces the risk that a network outage may become unrecoverable when the only management path follows the same failed control or data plane.

E:

A separate operational validation for A recovery procedure depends on an SSH jump host that resides behind the very campus link likely to fail is: The NOC reaches the switch through its approved management path during a simulated production uplink failure. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

A:

This alternative concerns lacp bandwidth and uplink resiliency planning; its associated risk is: A multi-chassis bundle planned without a supported peer technology can fail to aggregate or loop after partial failures. The observed case A recovery procedure depends on an SSH jump host that resides behind the very campus link likely to fail requires the more specific out-of-band management and management vrf design control. The targeted action is: Plan resilient management addressing, VRF separation, DNS, time, AAA and emergency access before connecting production uplinks.

C:

This alternative concerns implementation acceptance and requirements traceability; its associated risk is: A switch configuration that appears operational can still violate segmentation, availability or application service requirements absent explicit acceptance criteria. The observed case A recovery procedure depends on an SSH jump host that resides behind the very campus link likely to fail requires the more specific out-of-band management and management vrf design control. The targeted action is: Plan resilient management addressing, VRF separation, DNS, time, AAA and emergency access before connecting production uplinks.

D:

This alternative concerns dhcp relay and ip service planning; its associated risk is: A missing relay or permissive rogue-server path can leave new VLAN users disconnected or misconfigured. The observed case A recovery procedure depends on an SSH jump host that resides behind the very campus link likely to fail requires the more specific out-of-band management and management vrf design control. The targeted action is: Plan resilient management addressing, VRF separation, DNS, time, AAA and emergency access before connecting production uplinks.

Question 121

An HPE Aruba Networking engineer observes: A new guest VLAN cannot obtain addresses because its gateway has no route or relay to the central DHCP server. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which change best addresses the observed switching requirement?

  1. Map VLAN IDs, switchport tagging, Layer 3 gateways and traffic-policy boundaries to actual user and device populations.
  2. Identify client VLAN boundaries, relay targets, routing and DHCP protection controls so hosts obtain addresses from authorized servers.
  3. Translate customer requirements into tested topology, configuration, compatibility and handoff criteria before writing switch commands.
  4. Design link aggregation with compatible member speed, LACP state, switch support and upstream logical-system boundaries.

Explanation

Correct Answer

B:

The decisive observed condition is: A new guest VLAN cannot obtain addresses because its gateway has no route or relay to the central DHCP server. The appropriate switching action is: Identify client VLAN boundaries, relay targets, routing and DHCP protection controls so hosts obtain addresses from authorized servers. It addresses the risk that a missing relay or permissive rogue-server path can leave new VLAN users disconnected or misconfigured. Confirm with: A new host receives the intended address scope, gateway and DNS from an approved server across the routed boundary.

Incorrect Answers

A:

This alternative concerns vlan and subnet segmentation design; its associated risk is: A reused VLAN ID or unplanned trunk allowance can bridge separated device classes or silently block a required service. The observed case A new guest VLAN cannot obtain addresses because its gateway has no route or relay to the central DHCP server requires the more specific dhcp relay and ip service planning control. The targeted action is: Identify client VLAN boundaries, relay targets, routing and DHCP protection controls so hosts obtain addresses from authorized servers.

Question 122

An engineer investigates: A new guest VLAN cannot obtain addresses because its gateway has no route or relay to the central DHCP server. Which verification proves the intended operational state rather than just a saved configuration?

  1. A new host receives the intended address scope, gateway and DNS from an approved server across the routed boundary.
  2. A permitted test host reaches its gateway in the intended VLAN while cross-segment traffic follows the approved policy.
  3. A traceability matrix connects each requirement to an implementation decision, verification command or user-facing test.
  4. A lab simulates one member loss and verifies the logical LAG remains up with expected capacity and forwarding.

Explanation

Correct Answer

A:

The independent acceptance evidence for A new guest VLAN cannot obtain addresses because its gateway has no route or relay to the central DHCP server is: A new host receives the intended address scope, gateway and DNS from an approved server across the routed boundary. It tests whether the team has actually implemented: Identify client VLAN boundaries, relay targets, routing and DHCP protection controls so hosts obtain addresses from authorized servers. An enabled interface or saved configuration by itself is not evidence of complete service recovery.

Question 123

An HPE Aruba Networking engineer observes: A deployment assumes a broadcast DHCP discovery crosses a routed campus core automatically. The corrective solution must keep intended connectivity, segmentation, and operational resilience. What is the most defensible operational action before closing the network change?

  1. Design link aggregation with compatible member speed, LACP state, switch support and upstream logical-system boundaries.
  2. Identify client VLAN boundaries, relay targets, routing and DHCP protection controls so hosts obtain addresses from authorized servers.
  3. Select a consistent MSTP region/root placement or appropriate VSX/VSF active uplink design based on the actual Layer 2 topology.
  4. Translate customer requirements into tested topology, configuration, compatibility and handoff criteria before writing switch commands.
