The command erase all zeroize performs a secure erase on the switch, which deletes all customer data including startup-config and stored credentials. This process can take up to an hour depending on the hardware and storage media.

It does not retain running config (Option A).

It does not restore the factory AOS-CX image (Option B).

Admin credentials are deleted as part of the secure erase (Option C is incorrect).

Therefore, this command securely wipes all data and resets the device.

If the ISL between two VSX core switches is down and logs indicate that Core-2 has disabled its VSX LAG interfaces, it means Core-2 has disabled its VSX LAG interfaces, likely as a protective or failover mechanism.

Keepalive packets being dropped (Option B) may cause issues but logs specifically state interface disablement.

Both switches forwarding traffic (Option C) is unlikely if ISL is down.

Downstream switches inability to forward traffic (Option D) is a consequence, not the cause.

The issue is VMware vMotion traffic on VLAN 3903 failing, while other VLANs work normally. vMotion traffic requires support for larger frame sizes (jumbo frames) because vMotion packets are large and benefit from increased MTU to improve performance and reduce fragmentation.

Configuring jumbo frames on VLAN 3903 ensures that frames on this VLAN can use an MTU larger than the default 1500 bytes.

Configuring jumbo on the interface alone may not be sufficient if the VLAN itself is not set to support jumbo frames.

Setting MTU on VLAN or interface might not work unless jumbo frames are enabled.

To implement Dynamic User Roles (DUR) with Aruba ClearPass, an HTTPS certificate must be configured. This certificate enables secure communication between ClearPass and the Aruba CX switches for role downloading and authentication.

RadSec service enables secure RADIUS but is unrelated to DUR certificates.

Admin user roles and RADIUS dictionary attributes are necessary but secondary to certificate requirements.

Comprehensive Detailed Explanation:

To prevent man-in-the-middle attacks based on Layer 2 (Ethernet) addressing, enabling ARP inspection in the VLAN context is recommended. ARP inspection validates ARP packets and ensures only legitimate ARP responses are forwarded.

Enabling ARP inspection at VLAN level allows granular control.

Interface-level or global context is less typical or supported for ARP inspection on Aruba CX switches.

In HPE Aruba CX VSX, the hardware replacement of a single switch is non-disruptive for Layer 2 configurations because the system MAC address in the ServiceOS can be changed to the original system MAC address. This ensures consistent MAC address usage, avoiding disruptions in Layer 2 forwarding and preventing MAC flapping in the network.

Options involving VSX-sync or reserved system MAC ranges do not specifically address hardware replacement scenarios as effectively.

Changing the ServiceOS system MAC to match the original maintains Layer 2 stability during switch replacement.

The question relates to configuring port 1/1/44 on an Aruba CX 8325 switch to connect to a 2930F switch (Aruba 2930F series). The key factor is interoperability between these two devices, especially regarding link aggregation and port channel settings.

The Aruba 2930F typically uses static or LACP link aggregation with standard settings. To connect an Aruba CX 8325 port to a 2930F port, the CX configuration must align with the 2930F settings, particularly regarding:

Enabling LACP (Link Aggregation Control Protocol) on the port.

Correct VLAN tagging or trunk mode.

Matching speed and duplex settings.

From the options given, answer A corresponds to enabling LACP with appropriate trunk configuration that matches the 2930F. The other options either have mismatches in aggregation or trunking mode or missing LACP.
