Refer to the exhibit. An engineer is bringing up a new circuit to the MPLS provider on the Gi0/1 interface of Router1. The new circuit uses eBGP and teams the route to VLAN25 from the BGP path. What is the expected behavior for the traffic flow for route A. Traffic to is load balanced out of multiple interfaces B. Route is updated in the routing table as being learned from interface Gi0/1. C. Traffic to is a symmetrical D. Route learned via the Gi0/0 interface remains in the routing table.
Refer to the exhibit. A network technician is asked to design a small network with redundancy. The exhibit represents this design, with all hosts configured in the same VLAN. What conclusions can be made about this design? This design will function as intended. Spanning-tree will need to be used. The router will not accept the addressing scheme. The connection between switches should be a trunk.
Refer to the exhibit. When running EIGRP, what is required for RouterA to exchange routing updates with RouterC? AS numbers must be changed to match on all the routers Loopback interfaces must be configured so a DR is elected The no auto-summary command is needed on Router A and Router C Router B needs to have two network statements, one for each connected network.
Refer to the exhibit. Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router?
Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem? (Choose two.) All of the routers need to be configured for backbone Area 1. R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3. A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established. The hello and dead interval timers are not set to the same values on R1 and R3. EIGRP is also configured on these routers with a lower administrative distance. R1 and R3 are configured in different areas.
A network administrator is troubleshooting the OSPF configuration of routers R1 and R2. The routers cannot establish an adjacency relationship on their common Ethernet link.

The OSPF area is not configured properly. The cost on R1 should be set higher. The hello and dead timers are not configured properly. A backup designated router needs to be added to the network. The OSPF process ID numbers must match.
