QUESTION 178A network engineer has been tasked with designing a network for a new branch office with approximately 50 network devices. This branch office will connect to theother offices via a MAN. Many of the other branch offices use off-the-shelf SOHO equipment. It is a requirement that the routing protocol chosen use the leastamount of overhead. Additionally, all computers on the network will be part of a single VLAN. The connection between these computers should produce the highestthroughput possible, in the most cost effective manner.

Which of the following devices would be MOST appropriate?

A. A router should be used as a gateway device, with RIPv2 as the routing protocol. The computers should be connected to one another with a Gb Layer 2 switch.

B. A UTM should be used as a gateway device, with BGP as the routing protocol. The computers should be connected to one another using 1Gb Fibre Channel.

C. A router should be used as a gateway device, with EIGRP as the routing protocol. The computers should be connected to one another using a single 802.11NMIMO access point.

D. A router should be used as a gateway device, with OSPF as the routing protocol. The computers should be connected to one another using a Gb Layer 3 switch.




Explanation:A Gb Layer 2 switch is the cheapest switching solution offering 1Gbps network connectivity between the computers. RIPv2 has a lower overhead as required in thequestion.

Incorrect Answers:B: A 1Gb Fibre Channel network is expensive and is no faster than a 1Gbps network switch. Furthermore, the computers would require Fibre Channel networkadapters that do not come as standard on off-the-shelf computers.

C: An 802.11N MIMO access point is a wireless access point. These typically run at 300mbps which is slower than a 1Gbps network switch. Furthermore, thecomputers would require MIMO network adapters that do not come as standard on off-the-shelf computers.

D: A layer 3 switch is more expensive than a layer 2 switch. The question states that all the computers are in the same VLAN. Therefore, there is no need for inter-VLAN routing so a layer 3 switch is not required. OSPF also has a higher overhead than RIPv2.
