2) Consider the following CIDR blocks: 192.168.0.0/24 and 192.168.3.0/24. Identify the possible aggregated prefix (route summarization/supernetting) among the following.
a) 192.168.0.0/22 b) 192.168.0.0/23 c) 192.168.0.0/24 d) 192.168.0.0/25
3) Which of the following statements are true for Autonomous Systems (AS)?
a) The internet is composed of interconnected Autonomous Systems. b) It is administered by multiple authorities. c) BGP protocol is primarily used for communication between different Autonomous Systems (ASs). d) An Area in an Autonomous System (AS) is a collection of routers, networks, and hosts within an AS.
6) Consider the following topology of a network. Numbers labeled in the link between two routers represent cost. Using the Distance Vector algorithm, identify the updated distance vector at Router A after the first round of updates.
7) The Link State Routing Algorithm is/are NOT concerned with-
a) It shares the routing table rather than sending the information about its neighborhood only. b) Each router computes the shortest paths to all independently using Dijkstra’s algorithm. c) Each router does not have a complete view of the network topology. d) Once a router has detected a local link failure, it generates and floods a new LSP that no longer contains the failed link and the new LSP replaces the previous LSP in the network.
