QUESTION 11
What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?

A.    2
B.    4
C.    16
D.    unlimited

Answer: B
Explanation:
4 is the default number of routes that OSPF will include in routing table if more than 4 equal cost routes exist for the same subnet. However, OSPF can include up to 16 equal cost routes in the routing table and perform load balancing amongst them. In order to configure this feature, you need to use the OSPF subcommand maximum-paths, i.e. maximum-paths 16.

QUESTION 12
Which parameter would you tune to affect the selection of a static route as a backup, when a dynamic protocol is also being used?

A.    hop count
B.    administrative distance
C.    link bandwidth
D.    link delay
E.    link cost

Answer: B

QUESTION 13
What are two drawbacks of implementing a link-state routing protocol? (Choose two.)

A.    the sequencing and acknowledgment of link-state packets
B.    the requirement for a hierarchical IP addressing scheme for optimal functionality
C.    the high volume of link-state advertisements in a converged network
D.    the high demand on router resources to run the link-state routing algorithm
E.    the large size of the topology table listing all advertised routes in the converged network

Answer: BD
Explanation:
Link State routing protocols, such as OSPF and IS-IS, converge more quickly than their distance vector routing protocols such as RIPv1, RIPv2, EIGRP and so on, throught the use of flooding and triggered updates. In link state protocols, changes are flooded immediatedly and computed in parallel. Triggered updates improve convergence time by requiring routers to send an update message immediately upon learning of a route change. These updates are triggered by some event, such as a new link becoming available oor an existing link failing. The main drawbacks to link state routing protocols are the amount of CPU overhead involved in calculating route changes and memory resources that are required to store neighbor tables, route tables and a complete topology table.

QUESTION 14
Which two are advantages of static routing when compared to dynamic routing? (Choose two.)

A.    Configuration complexity decreases as network size increases.
B.    Security increases because only the network administrator may change the routing table.
C.    Route summarization is computed automatically by the router.
D.    Routing tables adapt automatically to topology changes.
E.    An efficient algorithm is used to build routing tables, using automatic updates.
F.    Routing updates are automatically sent to neighbors.
G.    Routing traffic load is reduced when used in stub network links.

QUESTION 15
Which command enables IPv6 forwarding on a Cisco router?

A.    ipv6 local
B.    ipv6 host
C.    ipv6 unicast-routing
D.    ipv6 neighbor

Answer: C
Explanation:
Administrative distance is the feature that routers use in order to select the best path. Administrative distance defines the reliability of a routing protocol. Each routing protocol is prioritized in order of most to least reliable (believable) with the help of an administrative distance value.Lowest Administrative distance will be choose first.EIGRP has 90 , RIP has 120 , OSPF has 110.

QUESTION 16
A router is running three routing processes: RIP, OSPF, and EIGRP, each configured with default characteristics. Each process learns a route to the same remote network. If there are no static routes to the destination and none of the routes were redistributed, which route will be placed in the IP routing table?

A.    the route learned through EIGRP
B.    the route learned through OSPF
C.    the route learned through RIP
D.    the route with the lowest metric
E.    all three routes with the router load balancing

Answer: A

QUESTION 17
What does a router do if it has no EIGRP feasible successor route to a destination network and the successor route to that destination network is in active status?

A.    It routes all traffic that is addressed to the destination network to the interface indicated in the routing table.
B.    It sends a copy of its neighbor table to all adjacent routers.
C.    It sends a multicast query packet to all adjacent neighbors requesting available routing paths to the destination network.
D.    It broadcasts Hello packets to all routers in the network to re-establish neighbor adjacencies.
