Open Shortest Path First (OSPF) is a dynamic routing protocol for use in Internet Protocol (IP) networks. Study the exhibit carefully, OSPF is used as the PE-CE protocol at all of these sites. Which path is preferred from CE1 to CE3?
Correct Answer: A
For the following mechanisms, which two could provide fast Layer 2 down detection in Frame Relay networks? (Choose two.)
A. asynchronous LMI
B. section 9 LMI convergence
C. A-bit signaling
D. millisecond LMI timers
Correct Answer: AC
Tom is a network administrator for the P4S Ltd. He is having problems with redistribution routing loops between two EIGRP processes. After studying the configurations, he determined there is no filtering configured on the routes being redistributed. In
order to avoid having a single point of failure, there are three routers configured to redistribute between the two routing protocols.
Which one of the following items is a solution to minimize management complexity?
A. replace one of the EIGRP processes with an alternate IGP
B. reduce the number of routers redistributing between the two routing processes
C. build and apply a route filter based on the networks being redistributed between the two processes
D. use tags to control redistribution between the two processes
Correct Answer: D
The following exhibit shows us that all the routers in this network are running EIGRP on all links. In Network
1, all links are the same cost. In Network 2, router P4S-RE prefers the path through P4S-RC, and does not have a feasible successor.
Which network converges faster in the event of the failure of the link between router P4S-RA and
A. network 1, because there are fewer query hops through the network
B. network 2, because there are more alternate paths available
C. network 2, because routers P4S-RC and P4S-RD have feasible successors
D. network 1, because all routers have feasible successors in this network
Correct Answer: A
A security analysis at The Potomac Canal Company recommends installing an IDS appliance and a firewall appliance. These appliances should connect directly into a Layer 3 switch. A load balancer and SSL termination have also been
recommended.Potomac’s management have expressed concern over the cost. You suggest using integrated blades. What is one
advantage and one disadvantage of your design proposal? (Choose two.)
A. The data center would need several devices to achieve its goal. B. Increased usage of standalone devices is cost-effective.
C. Using integrated blades would only require two devices.
D. Putting all security devices in a single chassis provides a single point of failure.
