Which HP Aruba feature automatically assigns a VLAN to a switch port based on the authenticated user's role or group membership?

Answer: Dynamic VLAN assignment via RADIUS

Dynamic VLAN assignment uses RADIUS server attributes returned after 802.1X authentication to place the port in the appropriate VLAN for that user.

What is the function of the HP Smart Storage Administrator (SSA) tool?

Answer: Configuring and monitoring HP Smart Array controllers and attached drives

HP SSA provides a graphical and CLI interface for configuring RAID arrays, monitoring drive health, and managing HP Smart Array controllers.

In an HP ProLiant server, which memory configuration provides the highest level of reliability by mirroring all data across two memory banks?

Answer: Mirrored memory (RAID-1 memory)

Mirrored memory mode duplicates all data across two memory channels, allowing the system to continue operating if one channel fails entirely.

Which command on an HP Aruba switch would display the current Spanning Tree state for all VLANs, including port roles and states?

Answer: show spanning-tree

The 'show spanning-tree' command displays STP topology information including port roles (root, designated, alternate) and states (forwarding, blocking, discarding).

HP StoreOnce uses which deduplication approach to maximize storage efficiency across multiple backup sources?

Answer: Variable-block, hash-based deduplication with Catalyst federation

HP StoreOnce uses variable-block deduplication with hash-based fingerprinting, and Catalyst allows deduplication to span multiple StoreOnce systems federated together.

What is the primary benefit of enabling 'flow control' (IEEE 802.3x) on HP switch ports connected to storage arrays?

Answer: It prevents packet loss by signaling the sender to pause transmission when buffers are full

IEEE 802.3x flow control uses PAUSE frames to temporarily halt transmission from the sender, preventing buffer overflow and packet loss on congested storage links.

An HP server running VMware ESXi needs to provide different network paths for VM traffic, vMotion, and management. Which HP networking feature best supports this separation?

Answer: HP Virtual Connect with multiple networks mapped to distinct vNICs

HP Virtual Connect allows multiple logical networks to be mapped to separate virtual NICs on each blade, enabling clean traffic separation for VM, vMotion, and management planes.
