4A0-103 practice questions, page 7 of 10, with answer review and explanations.

Question 31

Which approach to LSP path diversity provides the most control, but the least flexibility?

  1. Administrative Groups
  2. Shared Risk Link Groups
  3. Strict hop LSP paths
  4. Fast reroute

Question 32

If an Alcatel-Lucent 7750 LSR receives a labeled packet with a outer label TTL of 250 and an inner label TTL of 251, which of the following statements is true?

  1. The packet will be label switched; the outer label TTL will be 249 and the inner label TTL will be 250.
  2. The packet will be label switched; the outer label TTL will be 249 and the inner label TTL will be 251.
  3. The packet will be label switched; both the outer label TTL and the inner label TTL will be 250.
  4. The packet will be label switched; both the outer label TTL and the inner label TTL will be 249, because they must be the same.

Question 33

Which of the following statements best defines an LSP?

  1. An LSP is a bidirectional path across the MPLS domain.
  2. An LSP is a bidirectional path for a particular FEC across the MPLS domain.
  3. An LSP is a unidirectional path across the MPLS domain.
  4. An LSP is a bidirectional path between adjacent LSRs.
  5. An LSP is a unidirectional path between adjacent LSRs.
