Question 20

The HPE AOS-CX switching case is: A facilities review rejects a proposed modular switch because power and airflow assumptions were not tested against the rack. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)

  1. Evaluate a modular 6400-class distribution switch where line-card expansion, resiliency, optics and maintenance requirements justify chassis architecture.
  2. A module and transceiver map provides current and projected port capacity with power, cooling and resiliency allowances.
  3. Choose VSF when supported switches should operate as one logical stack and VSX when supported peer platforms require dual-control-plane multichassis connectivity.
  4. Choose between supported local CLI and HPE Aruba Networking Central workflows using management connectivity, scale, licensing and operational control requirements.
  5. A physical test validates optic compatibility, budgeted watts and negotiated interface speed on representative hardware.

Explanation

Correct Answers

A:

The targeted correction for A facilities review rejects a proposed modular switch because power and airflow assumptions were not tested against the rack is: Evaluate a modular 6400-class distribution switch where line-card expansion, resiliency, optics and maintenance requirements justify chassis architecture. It reduces the risk that an undersized fixed-port design can exhaust fiber terminations or require a disruptive wholesale replacement when the campus expands.

B:

A separate operational validation for A facilities review rejects a proposed modular switch because power and airflow assumptions were not tested against the rack is: A module and transceiver map provides current and projected port capacity with power, cooling and resiliency allowances. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

C:

This alternative concerns vsf versus vsx portfolio capabilities; its associated risk is: Treating VSX and VSF as synonymous can produce invalid cabling, platform selection and recovery expectations. The observed case A facilities review rejects a proposed modular switch because power and airflow assumptions were not tested against the rack requires the more specific 6400 chassis and modular distribution selection control. The targeted action is: Evaluate a modular 6400-class distribution switch where line-card expansion, resiliency, optics and maintenance requirements justify chassis architecture.

D:

This alternative concerns switching management and deployment portfolio decision; its associated risk is: Assuming cloud management is automatically available without entitlements and management reachability can leave new switches unmanaged. The observed case A facilities review rejects a proposed modular switch because power and airflow assumptions were not tested against the rack requires the more specific 6400 chassis and modular distribution selection control. The targeted action is: Evaluate a modular 6400-class distribution switch where line-card expansion, resiliency, optics and maintenance requirements justify chassis architecture.

E:

This alternative concerns optics interfaces and power portfolio constraints; its associated risk is: Unsupported optics or inadequate PoE and cooling may cause links to stay down even when a high-level product comparison looks acceptable. The observed case A facilities review rejects a proposed modular switch because power and airflow assumptions were not tested against the rack requires the more specific 6400 chassis and modular distribution selection control. The targeted action is: Evaluate a modular 6400-class distribution switch where line-card expansion, resiliency, optics and maintenance requirements justify chassis architecture.

Question 21

An HPE Aruba Networking engineer observes: A high-availability design assumes a chassis is automatically redundant without selecting the required supervisors and power supplies. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which implementation or troubleshooting step directly resolves the specific network issue?

  1. Evaluate a modular 6400-class distribution switch where line-card expansion, resiliency, optics and maintenance requirements justify chassis architecture.
  2. Choose VSF when supported switches should operate as one logical stack and VSX when supported peer platforms require dual-control-plane multichassis connectivity.
  3. Match supported Aruba AOS-CX aggregation and data-center-oriented platforms to throughput, port optics, routed fabric and licensing needs instead of assuming any high-speed chassis is interchangeable.
  4. Choose between supported local CLI and HPE Aruba Networking Central workflows using management connectivity, scale, licensing and operational control requirements.

Explanation

Correct Answer

A:

The decisive observed condition is: A high-availability design assumes a chassis is automatically redundant without selecting the required supervisors and power supplies.

Question 22

An engineer investigates: A high-availability design assumes a chassis is automatically redundant without selecting the required supervisors and power supplies. What network observation should the team require before approving completion?

  1. A topology review verifies selected switch models, expected management planes, ISL or stack links and documented failure behavior.
  2. A module and transceiver map provides current and projected port capacity with power, cooling and resiliency allowances.
  3. Feature and optic compatibility reports demonstrate the chosen series meets exact backbone throughput, topology and software requirements.
  4. A pilot provisions one intended model through the approved control plane and proves configuration changes and telemetry match the ownership plan.

Explanation

Correct Answer

B:

The independent acceptance evidence for A high-availability design assumes a chassis is automatically redundant without selecting the required supervisors and power supplies is: A module and transceiver map provides current and projected port capacity with power, cooling and resiliency allowances. It tests whether the team has actually implemented: Evaluate a modular 6400-class distribution switch where line-card expansion, resiliency, optics and maintenance requirements justify chassis architecture. An enabled interface or saved configuration by itself is not evidence of complete service recovery.

This alternative concerns campus access switch portfolio and endpoint density; its associated risk is: Choosing an entry access switch from the lowest purchase price alone can strand powered endpoints or omit the needed uplink and stacking feature. The observed case A proposed overlay design names a switching family that does not support the requested encapsulation on that release requires the more specific aos-cx aggregation and high-speed switching family fit control. The targeted action is: Match supported Aruba AOS-CX aggregation and data-center-oriented platforms to throughput, port optics, routed fabric and licensing needs instead of assuming any high-speed chassis is interchangeable.

This alternative concerns switching management and deployment portfolio decision; its associated risk is: Assuming cloud management is automatically available without entitlements and management reachability can leave new switches unmanaged.
