A 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 the other 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 least amount of overhead. Additionally, all computers on the network will be part of a single VLAN. The connection between these computers should produce the highest throughput possible, in the most cost effective manner.
Which of the following devices would be MOST appropriate? computers. RIPv2 has a lower overhead as required in the question. computers would require Fibre Channel network adapters that do not come as standard on off-the-shelf computers. than a 1Gbps network switch. Furthermore, the computers would require MIMO network adapters that do not come as standard on off-the-shelf computers. the same VLAN. Therefore, there is no need for inter-VLAN routing so a layer 3 switch is not required. OSPF
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 802.11N MIMO 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
Incorrect Answers:
B: A 1Gb Fibre Channel network is expensive and is no faster than a 1Gbps network switch. Furthermore, the
C: An 802.11N MIMO access point is a wireless access point. These typically run at 300mbps which is slower
D: A layer 3 switch is more expensive than a layer 2 switch. The question states that all the computers are in
also has a higher overhead than RIPv2.
