What are two reasons that a network administrator would use access lists? (Choose two.)

A. To control vty access into a router
B. To control broadcast traffic through a router
C. To filter traffic as it passes through a router
D. To filter traffic that originates from the router
E. To replace passwords as a line of defense against security incursions

Answer: A, C

Question:354
The above describes some features, while the below describes some routing protocols. Drag the above items to the proper locations. This question is to examine the characteristics of the RIPv1 and OSPF routing protocol. The advantage of the RIP protocol is of simple configuration, which is very applicable in small- scale network. The disadvantages of the RIP protocol include:

1. Mass Broadcast: RIP broadcasts a complete routing table every 30 seconds to all neighbors, which take up valuable bandwidth resources and will be a problem in slow WAN link.
2. RIP does not have the concepts of network delay and link costs. When using RIP, the decision of the routing /transmitting is based on the hops, which can easily cause the problem that there is no way to select the best route.
3. The limitation of the supported network scale. As RIP only supports a maximum of 16 step-by-step hops, the network is considered to be inaccessible when the hop number exceeds.
Therefore, RIP is only applicable in small-scale networks. The main advantages of the OSPF protocols lie in:
1. As it is based on the open standards, it can run on most of the routers.
2. It uses the SPF algorithm developed by the Dijkstra to provide loop-free topology.
3. It provides fast convergence of triggered update and incremental update through link state advertisement.
4. It is a classless protocol, which allows hierarchical design with VLSM and routing aggregation. The shortcomings of the OSPF protocol:
1. It requests more memory to maintain the adjacency relations (OSPF neighbor list), topology
(including all the routers and their link state database) and the routing table.
2. It requests extra CPU handling to perform the SPF algorithm, especially the first time they start up the router when they initially establish the adjacency relationship and the topology list.
3. As to large network, it requires careful design, to separate the network into appropriate hierarchical design through distributing the routers into different areas.
4. Its configuration is complicated and more difficult to troubleshoot.

Answer: A

Question:355
The left provides the definitions, while the right describes some terms. Drag the items on the right to the proper locations.

Answer: A

Question:356
The left provides some routing protocols, while the right gives several Cisco default administrator distances. Drag the items on the right to the proper locations.

Answer:A

Question:357
The left describes the security features, while the right describes the specific security risks.
Drag the items on the left to the proper locations. (Not all items can be used.) This question is to check the applications of encryption on devices in different modes and in different lines. It is easy if you know the concepts of different modes and lines.

Answer: A

Question:358
Please study the diagram carefully, and then drag and drop the network user application to the
appropriate description of its primary use(Not all options are used.)

Answer: A

Question:359
In order to enhance the security of Test enterprise network, Test network administrators use ACL(Access Control lists). What are two reasons that the Test network administrator would use access lists?

The purposes for setting ACLs on a router are controlling vty access into a router and filtering traffic as it passes through a router.

Access Control List(ACL) can be used to affect traffic transmitted from one port to another. It acquired its name due to having filtering capability when traffic flows in and out of interface and it also can be used for other purposes, such as:

A: Place restrictions on accessing router Telnet (VTY) .
B: Filter routing information.
C: Distinguish precedence of WAN traffic by queuing technology .
D: Trigger calls through the Dial-on-demand routing (DDR).
E: Change administrative distance of routing

Answer: A
