Why would an arcWhy would an architect use an OSPF virtual link?hitect use an OSPF virtual link?

• A. to merge two existing Area 0s through a nonbackbone
  

• B. to allow a stub area to transit another stub area
  
  

• C. to connect a nonbackbone area to Area 0 through another nonbackbone area

• D. to connect two networks that have overlapping private IP address space

How do the RIB and the FIB differ?

• A. FIB contains routes learned through a dynamic routing protocol, and the RIB contains routes that are static or directly connected.

• B. RIB contains the interface for a destination, and the FIB contains the next hop information.

• C. FIB is derived from the control plane, and the RIB is derived from the data plane.

• D. RIB is derived from the control plane, and the FIB is derived from the RIB.

In which two ways does the routing protocol OSPF differ from EIGRP? (Choose two)

• A. OSPF supports only equal-cost load balancing. EIGRP supports unequal-cost load balancing

• B. OSPF supports an unlimited number of hops. EIGRP supports a maximum of 255 hops

• C. OSPF is distance vector protocol. EIGRP is a link-state protocol

• D. OSPF provides shorter convergence time than EIGRP

• E. OSPF supports unequal-cost load balancing. EIGRP supports only equal-cost load balancing

In which way are EIGRP and OSPF similar?

• A. Both protocols support unequal-cost load balancing.

• B. Both protocols use hello packets to discover neighbors.

• C. Both protocols send updates using unicast addresses.

• 
  D. Both protocols support autosummarization.

Why does the OSPF neighborship fail between the two interfaces?

• A. The IP subnet mask is not the same.

• 
  B. There is a mismatch in the OSPF interface network type.

• C. The OSPF timers are different.

• D. The MTU is nor the same.

How does EIGRP differ from OSPF?

• A. EIGRP is more prone to routing loops than OSPF

• B. EIGRP supports equal or unequal path cost, and OSPF supports only equal path cost.

• C. EIGRP has a full map of the topology, and OSPF only knows directly connected neighbors

• 
  D. EIGRP uses more CPU and memory than OSPF

Which command when applied to the Atlanta router reduces type 3 LSA flooding into the backbone area and summarizes the inter-area routes on the Dallas router?

• A. Atlanta(config-route)#area 0 range 192.168.0.0 255.255.252.0

• B. Atlanta(config-route)#area 1 range 192.168.0.0 255.255.252.0

• C. Atlanta(config-route)#area 0 range 192.168.0.0 255.255.248.0

After a redundant route processor failure occurs on a Layer 3 device, which mechanism allows for packets to be forwarded from a neighboring router based on the most recent tables?

• A. RPVST+

• B. RP failover

• C. BFD

• D. NSF

When using BFD in a network design, which consideration must be made?

• A. BFD is used with first hop routing protocols to provide subsecond convergence.

• B. BFD is used with NSF and graceful to provide subsecond convergence.

• C. BFD is more CPU-intensive than using reduced hold timers with routing protocols.

• D. BFD is used with dynamic routing protocols to provide subsecond convergence.
