CCNA Questions

Answer : A  D

Explanation:

A and D are correct because successor route is the best and primary route to a remote network. A successor route is used by EIGRP to forward traffic to a destination and is stored in the routing table. Its backed up by a feasible successor route in case the primary route fails, that is stored in the topology table.

B is incorrect because neighbor table only contains a list of directly connected EIGRP routers that have an adjacency with this router, it doesn't contain successor routes.

C is incorrect because successor routes found in the routing table are not flagged as "active”

DNS uses TCP for zone exchanges between servers and UDP when a client is trying to resolve a hostname to an IP address.

An inside global address is considered to be the IP address of the host on the private network after translation.

In this question, we're calling EIGRP just plain old distance vector. EIGRP is an advanced distance-vector routing protocol, sometimes called a hybrid routing protocol because it uses the characteristics  of both distance-vector and link-state routing protocols.

The command ip nat pool name creates the pool that hosts can use to get onto the global internet. What makes option B correct is that the range 171.16.10.65 through 171.16.10.94 includes 30 hosts, but the mask has to match 30 hosts as well, and that mask is 255.255.255.224 . Option C is wrong because there is a lowercase t in the pool name. Pool name are case sensitive.

If you have a Cisco router on one side of a Frame Relay network and a non-Cisco router on the otherside, you would need to use the Frame Relay encapsulation type of IETF. The default is Cisco encapsulation, which means that a Cisco router must be on both sides of the Frame Relay PVC.

Only the EIGRP routes will be placed in the routing table because it has the lowest administrative distance (AD), and that is always used before metrics.

The key is "there are no free ports" on your router. Only Frame Relay can provide a connection to multiple locations with one interface, and in an economical manner no less.
