Why would a Cisco network designer recommend variable-length subnet masking for a network?

• A.to implement classless routing
• B.to minimize convergence time

• D.to suit the flat structure of the network
• E.to accommodate a mixed vendor environment

You are the only experienced network engineer for a small independently owned chain of companies, Cisco Inc. The CEO wants to have all the offices interconnected to the head office due to most IT personnel being based at the head office. Cisco wants a simple network topology where branch offices are to connect to regional offices and regional offices will connect to the head office.
The headquarters consists of a large campus. To be cost effective, the CEO does not want redundant links. Also, they want maximum throughput for the branch offices and little or no overhead traffic.
Which routing option would you suggest for the small office?

• A.Dynamic routing, hybrid protocol
• B.Dynamic routing distance vector protocol
• C.Static routing protocol
• D.Variable length subnetwork masking protocol
• E.Multi protocol label switching protocol

What is the benefit of VLSM?

• A.reduces configuration complexity by using the same subnet mask length
• B.secures the hosts on a subnet by using RFC 1918 addresses
• C.allows the advertisement of the subnet mask along with the classful routing updates
• D.conserves IP addresses by using different subnet mask length
• E.reduces the routing table size by using automatic summarization
