Routing moves a letter or telephone call to the access layer (as in a street or telephone exchange). Switching makes the final delivery. A switching decision is made on the part of the address that is not used in routing (as in the street number or last four digits of a phone number).

Answer : E

Answer : B

Explanation :

This is one of those tricky questions just to test your knowledge of routing protocols and their administrative distance. Let’s look at the AD of popular routing protocols below:
 Routing Protocol (Source)                           AdministrativeDistance(AD)                                                             

  Directly connected                                        0

  Static Route                                                  1

  EIGRP                                                           90

  Summary Route(EIGRP)                              5

  OSPF                                                           110

  RIP                                                              120

Fom the above table, you can see that EIGRP has the lowest AD from all of the above mentioned routing protocols. So, the router will choose to use the routing protocol which has lowest Administrative Distance which in this case is B. EIGRP

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”

Answer : F

Explanation :     In each group of 3 boxes, calculate the difference in numerical values between the top two letters, and add 1 to give the value of the letter in the lower box

Answer: J

Explanation:   Start with the letter J in the top left square, and move clockwise around the other squares. Letters follow the alphabetic sequence, skipping 4 letters at a time. Start with the X in the inner square in the top left, and move clockwise. These inner letters also follow the alphabetic sequence, skipping 5 letters at a time

Answer: D

Explanation:    The diagram contains 3 sets of 4 letters - one set of outer corner letters, one set of inner corner letters, and one set of letters on each side of the square. The numerical values of the letters in each set add up to 40.
