A technician is installing a VSX pair of CX 8360 switches. They have connected the 100GbE DAC cables for the ISL. Before configuring the VSX software, they need to verify the physical link status. Upon checking, the ISL ports are down. What is the most likely cause, assuming the cables are functional?
Show answer details
Correct answer: C
In AOS-CX, unlike some other switch operating systems, physical interfaces are administratively
shutdownby default. Even with a valid cable connected, the link will show as down until theno shutdowncommand is issued on the interface. - 2
You are performing a firmware upgrade on a VSX cluster of CX 6400 switches. The customer requires zero downtime for connected dual-homed servers. Which upgrade method should you utilize?
Show answer details
Correct answer: C
The
vsx update-softwarecommand initiates an orchestrated upgrade process (often called VSX Live Upgrade). It upgrades the secondary member first, waits for it to reboot and rejoin, then upgrades the primary member. This ensures that dual-homed devices (connected via MC-LAG) traffic is seamlessly shifted to the active peer, maintaining connectivity throughout the process. - 3
You are installing a new CX 8325 switch that will be managed by Aruba Central. You have connected the management port to a network with internet access. What is the default method the switch will use to discover the Aruba Central server?
Show answer details
Correct answer: A
By default, AOS-CX switches attempt to contact the Aruba Activate service (device.arubanetworks.com) via HTTPS. Activate acts as a redirection service that points the switch to the appropriate Aruba Central instance based on the device's inventory assignment.

A financial institution is designing a new data center fabric using HPE Aruba Networking CX 8325 switches. The design requires a leaf-spine topology with EVPN-VXLAN for multi-tenancy. The architect needs to ensure that routing between different VRFs occurs at the leaf switches to minimize latency and traffic hair-pinning. Which Integrated Routing and Bridging (IRB) model should be specified in the Low-Level Design (LLD)?
Show answer details
Correct answer: D
Symmetric IRB uses a transit VNI (L3 VNI) to route traffic between different VNIs/VRFs directly at the ingress leaf (or egress leaf depending on flow). This model supports distributed Layer 3 gateways on all leaf switches, allowing inter-VRF routing to occur at the edge without hair-pinning traffic to a spine or border leaf, thus optimizing latency.

You are verifying the Bill of Materials (BoM) for a high-performance compute cluster. The design calls for CX 8360-48Y6C switches to connect servers using 25GbE interfaces. The servers are located in the same rack as the switch, with a maximum distance of 3 meters. To minimize cost and power consumption while ensuring reliability, which cabling solution should be validated in the BoM?
Show answer details
Correct answer: B
For short distances (typically up to 3-5 meters) within a rack, Passive Direct Attach Copper (DAC) cables are the most cost-effective and power-efficient solution. They do not require separate transceivers and consume less power than Active Optical Cables (AOC) or SR transceivers.

An architect is designing an underlay network for a 3-stage Clos topology using AOS-CX switches. The requirement is to support ECMP load balancing across all available paths. Which routing protocol design choice best supports this requirement while minimizing configuration complexity for a large-scale deployment?
Show answer details
Correct answer: D
Using eBGP for the underlay is a standard best practice in modern data center fabrics. Assigning a unique AS per leaf and a common AS for spines simplifies configuration (using peer-groups) and naturally prevents loops via AS_PATH, while supporting extensive ECMP capabilities without the flooding scope limitations of OSPF in very large fabrics.
