Explanation

RSPAN Session Configuration Explanation

RSPAN (Remote Switched Port Analyzer) requires a specially designated RSPAN VLAN to carry the mirrored traffic across the network to the remote destination switch - this VLAN must be explicitly configured as type "remote-span," which restricts it from carrying normal user traffic and dedicates it solely to monitoring purposes.

Why the distractors are wrong:

• Option A is incorrect because filters are optional in RSPAN, not mandatory - they can be used to refine what traffic is captured, but are not required.
• Option B is false because most Cisco switches support multiple simultaneous SPAN/RSPAN sessions, not just one.
• Option D is incorrect because RSPAN can monitor both ingress (incoming) and egress (outgoing) traffic, or both simultaneously, giving full flexibility.

Memory Tip: Think of the RSPAN VLAN as a "dedicated highway" - just like a special express lane reserved only for specific vehicles, the RSPAN VLAN is a reserved, special-type VLAN that only carries mirrored/monitoring traffic, and no regular traffic is permitted on it. If you remember "RSPAN = special VLAN required," you'll always get this right!
