All routers in this network are running EIGRP according to the exhibit.
Which step is the most important to make sure that this network core will converge quickly should a link
A. make certain the maximum number of paths on both of the routers is two
B. make certain EIGRP is not running across non-transit links
C. add another link between the two routers with no servers and set the metric on this new link equal to the other four links
D. make certain EIGRP is running across all links
Correct Answer: B

When designing a converged network, which measures can be taken at the building access layer to help eliminate latency and ensure end-to-end quality of service can be maintained? (Choose three.)
A. rate limit voice traffic
B. onfigure spanning-tree for fast link convergence
C. isolate voice traffic on separate VLANs
D. classify and mark traffic close to the source
Correct Answer: BCD

Which two reasons are correct about building a flooding domain boundary in a link-state network? (Choose two.)
A. to increase the size of the Shortest Path First tree
B. to aggregate reachability information
C. to provide an administrative boundary between portions of the network
D. to segregate complex and rapidly changing portions of the network from one another
Correct Answer: BD

The P4S company is planning to deploy a new multicast application in its network to do real-time trading. This application will be performed simultaneously by thousands of traders located throughout the network, each a source of several IP multicast streams, to
carry the “sell” and “buy” trading bids. All routers in its network have full hardware support for all PIM
multicast modes.
Which mode can be used to minimize the impact of the new application on the routers in the P4S network?
A. PIM Source Specific Multicast
B. PIM Any-Source Multicast
C. PIM Dense Mode
D. PIM Bidirectional
Correct Answer: D

You work as a network technician for the P4S Ltd. Study the exhibit carefully, router P4S-RA is the hub router in a Frame Relay hub-and-spoke deployment. Configure router P4S-RA’s serial interface as a point- to-multipoint interface, and it is servicing three
spoke routers. The link between Router P4S-RC and the frame provider experiences a service disruption, which causes the interface
on Router P4S-RC to go down.
How does Router P4S-RA learn of this failure in the network and how does it react?
A. If OAM is configured between Router P4S-RA and Router P4S-RC, router P4S-RA will be notified of the failure after three
missed OAM packets. After the third OAM packet is missed, the frame PVC becomes inactive, and this event terminates the
routing process neighbor relationship established between Router P4S-RA and Router P4S-RC.
B. Router P4S-RA does not detect the failure in the network and its interface continues to remain in an operational state. If
routing is configured over this link, Router P4S-RA must wait for the neighbor relationship to time-out before updating its
routing table to account for the lost router and its networks.
C. Router P4S-RA must wait for a full LMI status update from the provider frame switch before it is notified about the PVC status.
Once the full LMI status message is received, the routing process neighbor relationship between Router
P4S-RA and Router
P4S-RC is immediately terminated.
D. Router P4S-RA immediately detects the failure via LMI notification and its interface is placed in a non- operational state. If
routing is configured over this link, the neighbor relationship is terminated and the routing table is updated. The change is
then propagated as appropriate to the rest of the network.
