Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A single port can be a SPAN source for multiple SPAN sessions simultaneously.
Cisco switches have limits on the number of SPAN/RSPAN sessions, typically up to 2 local SPAN sessions and 1 RSPAN source session. A single port can be a source for multiple sessions, but a destination port can only be used in one session at a time. The source and destination ports must be on the same switch for local SPAN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A single port can be a SPAN source for multiple SPAN sessions simultaneously.
Why this is correct
Correct because a source port can be monitored by multiple SPAN sessions.
- ✗
A SPAN destination port can be used in multiple SPAN sessions at the same time.
Why it's wrong here
Incorrect because a destination port can only be used in one SPAN session at a time.
- ✓
RSPAN source sessions and local SPAN sessions count toward the same session limit on a switch.
Why this is correct
Correct because the session limit (e.g., 2) applies to both local and RSPAN source sessions combined.
- ✗
The maximum number of SPAN sessions on a switch is always 4.
Why it's wrong here
Incorrect because the maximum varies by platform; many Catalyst switches support only 2 sessions.
- ✗
A SPAN source VLAN can be used in both a local SPAN and an RSPAN session at the same time.
Why it's wrong here
Incorrect because a VLAN can be a source in only one SPAN session (local or RSPAN) at a time.
