Module 6: Quiz

Question 1

Using packet classification techniques we can perform packet forwarding based on multiple criteria, and not just based on destination IP address.

True/False

Answer 1

True

Question 2

The backtracking approach has a higher cost in terms of time, whereas the set-pruning approach has a higher cost in terms of memory.

True/False

Answer 2

True

Question 3

The grid of tries technique offers a “middle ground” approach, merging the backtracking and the set-pruning techniques.

True/False

Answer 3

True

Question 4

The head-of-line blocking refers to the problem when an entire queue remains blocked because the head of the queue is blocked. 

True/False

Answer 4

True

Question 5

One technique to avoid head of line blocking is with parallel iterative matching.

True/False

Answer 5

True

Question 6

With parallel iterative matching the input links are “matched” with output links in a fixed manner that stays the same as the rounds are progressing.

True/False

Answer 6

False

Question 7

With the token bucket traffic approach, we can still have bursts of traffic entering the network, but these bursts are capped.

True/False

Answer 7

True

Question 8

With the leaky bucket approach, we only allow the traffic to enter the network in a configured rate.

True/False

Answer 8

True

Question 9

Traffic policers target to limit traffic bursts to a configured max, whereas traffic shapers target to smooth out the overall rate.

True/False

Answer 9

True

Question 10

With the leaky bucket we can still have discarded packets.

True/False

Answer 10

True
