• Question 44:

  Which of the following statements are TRUE? (Choose two)

  A. The primary contributors to latency are distance, scheduling, and congestion.
  B. The weighted round robin scheduling algorithm will result in more delay for high priority traffic than the regular round robin algorithm.
  C. The round robin scheduling algorithm will result in less jitter for low priority traffic than a strict priority scheduler.

• Question 47:

  A packet is to be encapsulated inside an MPLS tunnel which consists of two MPLS headers at the first network egress. Which of the MPLS EXP fields will be marked?

  A. The EXP field in the bottom MPLS header will be marked.
  B. The EXP field in both the top and bottom MPLS headers will be marked.

  D. The EXP field in the top MPLS header will be marked.
  E. Neither the top nor the bottom EXP field will be marked since EXP remarking can only be done on the network ingress.
