Demo Questions
Question 1
What is the SA in the Ethernet frame used for by a layer 2 switch?
- MAC learning
- SA filtering
- Routing table population
- Frame forwarding
Correct answer: A
Question 2
What are the limitations of a traditional layer 2 switch? (Choose 3}
- Isolates collision domains.
- Requires layer 2 loop prevention.
- Slow response to topology changes.
- Limited to 4094 vlans per switch.
- Increased flooding.
Correct answer: BCD
Question 3
Assuming TLDP and RSVP are both being used in an MPLS network core which of the following statements is true?
- TLDP is used to create the inner label, RSVP is used to create the outer label.
- TLDP is used to create the outer label, RSVP is used to create the inner label.
- TLDP and RSVP cannot be used in the same network since they both provide the same label.
- When RSVP is used, TLDP must be disabled and static vc labels should be used.
- TLDP and RSVP can be used to create either labels based on how they are configured.
Correct answer: A
Question 4
Fill in the blank for this next sentence. Flooded traffic received on any ____________ in the service is replicated to other spoke SDPs and SAPs and not transmitted on any mesh SDPs.
- Spoke SDP
- Mesh SDP
- Either (a) or (b) will make this sentence true.
- Neither (a) nor (b) will make this sentence true.
Correct answer: B
Question 5
Port 1/1/1 has been configured as an access port with QinQ encapsulation. Which of the following three statements are true for ingress traffic assuming default configuration?
(Choose 3)
- sap 1/1/1:*.0 is a valid sap id.
- sap 1/1/1:100* will accept frames with a single tag of 100.
- sap 1/1/1:200* will strip the top tag of 200 and the bottom tag will be transparently passed.
- sap 1/1/1:0* will accept all untagged frames.
- sap 1/1/1:0* will accept any tagged frames.
Correct answer: BCD
Question 6

- All frames with more than one tag will be dropped.
- The source MAC address of a frame with a single tag of 500 will be populated in VPLS 1.
- The source MAC address of a frame with a top tag of 100 will be populated in VPLS 2.
Correct answer: E

- TRUE
- FALSE
Correct answer: B
