New CCNA – Drag and Drop 5

 

Here you will find answers to Drag and Drop Questions – Part 5

Question 1

Drag the Cisco default administrative distance to the appropriate routing protocol or route (Not all options are used)

 

Answer:

+ RIP: 120
+ OSPF: 110
+ static route referencing IP address of next hop: 1
+ internal EIGRP route: 90
+ directly connected network: 0

Question 2

Drag the term on the left to its definition on the right (not all options are used)

 

Answer:

+ poison reverse: A router learns from its neighbor that a route is down and the router sends an update back to the neighbor with an infinite metric to that route
+ LSA: The packets flooded when a topology change occurs, causing network routers to update their topological databases and recalculate routes
+ split horizon: This prevents sending information about a routeback out the same interface that originally learned about the route
+ holddown timer: For a given period, this causes the router to ignore any updates with poorer metrics to a lost network

Question 3

Drag the description on the left to the correct router mode on the right

 

Answer:

+ user EXEC mode: limited to basic monitoring commands
+ privileged EXEC mode: provide access to all other router commands
+ global configuration mode: commands that affect the entire system
+ specific configuration mode: commands that affect interfaces/processes only
+ setup mode: interactive configuration dialog

Question 4

Drag each definition on the left to the matching term on the right

 

Answer:

+ cost: a configurable value based by default on the bandwidth of the interface
+ load: the amount of activity on a network resource
+ bandwidth: the data capacity of a link
+ hop count: the number of point-to-point links in a transmission path
+ reliability: usually refers to the bit error rate of each network link
+ delay: the amount of time required to move a packet from source to destination

Question 5

Refer to the exhibit. Complete the network diagram by dragging the correct device name or description to the correct location. Not all the names or descriptions will be used.



 

Answer:

From left to right:

Router, DTE, DCE, CSU/DSU Synchronous, Digital Line, WAN Service Provider Network.

 

Question 6

Drag each feature on the left to the appropriate routing protocol on the right.



 

Answer:

RIP version 1

+ sends frequent updates
+ less complex configuration
+ susceptible to routing loops
+ exchanges full routing table in updates

OSPF:

+ faster convergence
+ uses only event-triggered updates
+ same topology information held by all routers
+ requires more memory and processing power

Question 7

Drag item on left to match item on right



 

Answer:

+ Point to Point Advantage: Quality
+ Point to Point Disadvantage: Limited Flexibility
+ Circuit Switched Advantage: Cost
+ Circuit Switched Disadvantage: Low speed
+ Packet Switch Advantage: Efficient
+ Packet Switch Disadvantage: More Complex

Question 8

All hosts in the same subnet with 172.16.5.118/26 must be denied Telnet access to hosts outside the LAN (u need to just drag & drop) fill out the command. To complete the bracketed command, [access-list list-number deny tcp 172.16.5.address 0.0.0.mask any eq port], drag each appropriate option on the left to its proper placeholder on the right. (Not all options are used)



 

Answer:

+ list-number: 128
+ address: 64
+ mask: 63
+ port: 23

Explanation

In this case we want to filter port number so we have to use extended access-list so the list-number of our access-list must be from 100 to 199 -> We can choose 128. We need to find the range of the subnet 172.16.5.118/26:

Increment: 64 (/26 = 1111 1111. 1111 1111. 1111 11111. 1100 0000)
Network address: 172.16.5.64
The corresponding wildcard mask for /26 is 0.0.0.63 (because 63 = 0011 1111)

The port of Telnet access is 23 (and Telnet uses TCP). It is a well-known port that you must remember.

Therefore the full command to deny Telnet access to hosts outside the LAN 172.16.5.64 is:
access-list 128 deny tcp 172.16.5.64 0.0.0.63 any eq 23
