QUESTION 1 Which of the following is not true regarding a software defined networking (SDN) based control pane? The remote controller will utilize a distributed routing algorithm such a Bellman-Ford in order to compute optimal paths. The remote controller maintains link-state information across all routers within its scope. The remote controller relieves routers of the responsibility of making routing decisions themselves. The remote controller is responsible for calculating a forwarding table for every router i its scope QUESTION 2 Consider the following forwarding table in a router Prefix 145.132.48.0/20 146.91.121.0/24 145.132.48.0/22 145.132.48.0/24 145.132.56.0/22 Edge A B с D E Suppose the router receives a datagram that is destined for 145.132.50.100. To which edge should it be forwarded? OA OB OC OD ОЕ QUESTION 3 Which of the following router queuing policies might result in a situation where it is possible for a datagram to get stuck in the queue indefinitely (without being dropped)? First-in-first-out (FIFO) O Random selection of a datagram O Round Robin across multiple queues Process the datagram with the shortest payload first QUESTION 4 Consider the subnet 123.45.24.0/21, which can support up to 2048 hosts. Which of the following sets of 4 subnets represent a partitioning of this subnet into 4 equally sized subset subnets of size 512 hosts each? 123.45.24.0/23 123.45.25.0/23 123.45.26.0/23 123.45.27.0/23 123.45.24.0/23 123.45.24.1/23 123.45.24.2/23 123.45.24.3/23 O 123.45.24.0/22 123.45.24.2/22 123.45.24.4/22 123.45.24.6/22 123.45.24.0/22 123.45.24.1/22 123.45.242/22 123.45.24.3/22 123.45.24.0/23 123.45.26.0/23 123.45.28.0/23 123.45.30.0/23 0 0
