HP Updated HPE7-A08 Exam Questions and Answers by ivy-rae

The Building B access switch must be changed from the CX 6100 to the CX 6200 because the CX 6100 does not support Always-on PoE , while the CX 6200 does. HPE Aruba ' s AOS-CX documentation explicitly states that the power-over-ethernet always-on command is unavailable on the 6100 series. Always-on PoE maintains power to already-powered devices during a switch software reboot, which is essential when connected devices such as APs must remain powered during maintenance or an AOS-CX restart.

The CX 6200F also provides appropriate access-layer configurations, including 48-port Class 4 PoE models with four SFP+ uplinks , making it a direct functional replacement for the depicted CX 6100 access switch. Aruba Networks

The specified fiber distance does not require changing the optical design. Aruba ' s transceiver guidance specifies that 10GBASE-SR over OM3 multimode fiber supports up to 300 m , so the stated 200 m / 656 ft run remains within specification. Aruba Networks

CX 8320 and CX 8100 are aggregation/data-center platforms rather than PoE access-switch replacements. Although CX 4100i supports Always-on PoE, it is an industrial access platform and does not match the depicted 48-port campus-access requirement.

During a VSX firmware upgrade, the vsx-syned process stops synchronization while the switches have mismatched software versions. Synchronization resumes once both switches run the same software.

VSX synchronization cannot continue while versions mismatch (contrary to options B and D).

Compatibility mode is not required before rebooting secondary switch (Option D incorrect).

This behavior ensures consistency and avoids split-brain during upgrades.

In the Aruba/HPE troubleshooting framework, the methodology is selected based on the information provided at the start of the engagement.

Follow the Path: Since you have the Source IP and Destination IP, you have a clear starting and ending point. This methodology involves identifying every hop (switches, routers, firewalls) between the client and the SQL server.

Execution: You would typically use tools like traceroute, check interface statistics for errors/drops on each switch in the path, and look for specific buffer or congestion issues that could cause " intermittent " loss.

Why others are less ideal: * Divide and Conquer: Better for situations where you don ' t know the full path but know the issue is likely at a specific layer (e.g., Layer 3).

Spot the Difference: Used when one server works and another doesn ' t; here, we are troubleshooting a single, specific intermittent path.

Top-down/Bottom-up: These are systematic but time-consuming. When you have the IPs, " Follow the path " is the most direct and efficient diagnostic choice.

(Note: Corrected the typo in the original prompt where " Online " was used instead of " Only " .)

Redistribution between an Exterior Gateway Protocol (BGP) and an Interior Gateway Protocol (OSPF) is a high-risk operation on AOS-CX switches that requires careful planning.

Scale and Performance: BGP is designed to carry thousands (or even millions) of routes. OSPF is a link-state protocol that requires every router in an area to maintain an identical Link State Database (LSDB). If you were to redistribute a full BGP table into OSPF, the resulting flood of Type 5 LSAs would likely crash the OSPF process, consume all available switch memory, and cause network-wide instability.

The " Only Defined Routes " Rule: Aruba best practices dictate that you should use Route Maps to strictly control (define) which specific BGP prefixes are allowed into the OSPF domain. This ensures only necessary destination networks (like a remote branch office) are advertised to the campus routers, protecting the OSPF area ' s resources.

Evaluating Other Options:

Option A: While redistributing only a default route is a very safe strategy, it isn ' t a " universal truth " because some designs require specific internal subnets to be shared.

Options B and C: Choosing between External Type 1 (E1) and External Type 2 (E2) is a design choice regarding how costs are calculated (E1 adds internal path cost, E2 stays constant). Neither is an " always " requirement; the primary concern is the volume and definition of the routes being moved.
