Answer: C

Explanation:

UDLD (Unidirectional Link Detection) is the information that the Inter-Switch Link Protocol configuration uses in the configuration created for Aruba CX VSX pair inter-switch-link. UDLD is a protocol that detects unidirectional links between switches and prevents loops or black holes in the network. UDLD is enabled by default on all ports that are part of the inter-switch-link between VSX peers. The other options are incorrect because they are either not related to inter-switch-link or not supported by Aruba CX VSX.
