Q:

As a Cisco technician, you need to know EIGRP protocol very well. Which of the following is true about EIGRP successor routes? (Choose two)

A. A successor route is used by EIGRP to forward traffic to a destination
B. Successor routes are stored in the neighbor table following the discovery process
C. Successor routes are flagged as "active" in the routing table
D. A successor route may be backed up by a feasible successor route

Answer

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”

Q:

If you wanted to deny all Telnet connections to only network 192.168.10.0, which command could you use?

A) access-list 100 deny tcp 192.168.10.0 255.255.255.0 eq telnet B) access-list 100 deny tcp 192.168.10.0 0.255.255.255 eq telnet
C) access - list 100 deny tcp any 192.168.10.0 0.0.0.255 eq 23 D) access - list 100 deny 192.168.10.0 0.0.0.255 any eq 23
 
Answer & Explanation Answer: C) access - list 100 deny tcp any 192.168.10.0 0.0.0.255 eq 23

Explanation:

The extended access list ranges are 100 - 199 and 2000 - 2699, so the access-list number of 100 is valid. Telnet uses TCP, so the protocol TCP is valid. Now you just need to look for the source and destination address. only the third option has the correct sequence of parameters. Option B may work, but the question specifically states "only" to network 192.168.10.0, and the wildcard in option B is too broad.

Q:

A network administrator needs to configure a router with a distance-vector protocol that allows classless routing. Which of the following satisfies those requirements?

A) IGRP B) OSPF
C) RIPv1 D) EIGRP
 
Answer & Explanation Answer: D) EIGRP

Explanation:

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.

Q:

Which command will create a dynamic pool named Todd that will provide you with 30 global addresses?

A) ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.240 B) ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224
C) ip nat pool todd 171.16.10.65 171.16.10.94 net 255.255.255.224 D) ip nat pool Todd 171.16.10.1 171.16.10.254 net 255.255.255.0
 
Answer & Explanation Answer: B) ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224

Explanation:

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.
