Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 178
Which two statements about SPAN source and destination ports during an active session are true? (Choose two.)
Answer options
- A. The source port can be only an Ethernet physical port.
- B. The source port can be monitored in multiple SPAN sessions.
- C. The destination port can be destination in multiple SPAN sessions.
- D. The destination port does not participate in STP.
- E. You can mix individual source ports and source VLANs within a single session.
Correct answer: B, D
Explanation
Option B is correct because a source port can indeed be monitored across multiple SPAN sessions, allowing flexibility in monitoring. Option D is also correct as the destination port does not participate in Spanning Tree Protocol (STP), which is important for traffic mirroring. Options A, C, and E are incorrect because the source port can be more than just an Ethernet port, the destination port cannot be in multiple sessions, and mixing source ports with source VLANs is not permitted in a single session.
