QUESTION 15
A network engineer is upgrading a small data center to host several new applications, including server backups that are expected to account for up to 90% of the bandwidth during peak times. The data center connects to the MPLS network provider via a primary circuit and a secondary circuit. How does the engineer inexpensively update the data center to avoid saturation of the primary circuit by traffic associated with the backups?

1. 
   Place the backup servers in a dedicated VLAN.
   
2. 
   Configure a dedicated circuit for the backup traffic.
   
3. 
   Assign traffic from the backup servers to a dedicated switch.
   
4. 
   Advertise a more specific route for the backup traffic via the secondary circuit.
   

Correct Answer: D

The network engineer is configuring router R2 as a replacement router on the network. After the initial configuration is applied it is determined that R2 failed to show R1 as a neighbor. Which configuration must be applied to R2 to complete the OSPF configuration and enable it to establish the neighbor relationship with R1?

1. 
   R2(config)#interface g0/0/0 R2(config-if)#ip ospf hello-interval 10
   
2. 
   R2(config)#router ospf 1
   

R2(config-router)#router-id 192.168.1.1

3. 
   R2(config)#router ospf 1
   

R2(config-router)#network 192.168.1.0 255.255.255.0 area 2

4. 
   R2(config)#interface g0/0/0 R2(config-if)#ip ospf dead-interval 45
