Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 169

Which two limitations of local SPAN are true? (Choose two.)

Answer options

• A. Each SPAN session supports only one source VLAN or interface
• B. A switch can support only one local SPAN session at a time
• C. It can monitor only traffic that ingresses or egresses on the source interface or VLAN
• D. A SPAN session can support multiple destination ports only if they are on the same VLAN
• E. The source and destination ports must reside in the same switch or switch stack

Correct answer: C, E

Explanation

Answer C is correct because local SPAN only captures traffic that enters or exits the specified source interface or VLAN. Answer E is also correct as local SPAN requires that both source and destination ports must be located within the same switch or switch stack. Options A, B, and D are incorrect as they do not accurately represent the limitations of local SPAN.
