QUESTION 24 You are a network technician at Cisco Highway. You have subnetted the 210.106.14.0 network with a /24 mask. Your supervisor asks you how many usable subnetworks and usable host addresses per subnet this would make provision for. What would your response be?

A. 1 network with 254 hosts

B. 4 networks with 128 hosts

C. 2 networks with 24 hosts

D. 6 networks with 64 hosts

E. 8 networks with 36 hosts Answer: A Explanation: A subnet with 24 bits on would be 255.255.255.0. This subnet has only 1 network and 254 hosts.

QUESTION 25 You are a network technician at Cisco Highway. Due to rapid expansion, Cisco Highway is leaning towards scalable WAN technology. Immediate plans for the company include an additional 7 regional offices with all sites requiring continuous connectivity, but the current head office has no free ports available. Which of the following WAN technologies will meet the requirements?

A. Frame Relay

B. Broadband cable

C. ISDN-BRI

D. ADSL

E. Dedicated PPP/HDLC Links

F. ISDN Answer: A

QUESTION 26 You are a network technician at Cisco Highway. You apply the access list illustrated below to interface E0 on a Cisco router. The interface is connected to the 192.168.1.8/29 LAN. access-list 123 deny tcp 192.168.166.18 0.0.0.7 eq 20 any access-list 123 deny tcp 192.168.166.18 0.0.0.7 eq 21 any What are the consequences of this specific access list?

A. All traffic will be allowed to exit E0 except FTP traffic.

B. FTP traffic from 192.168.166.19 to any host will be denied.

C. FTP traffic from 192.168.166.22 to any host will be denied.

D. All traffic exiting E0 will be denied.

E. All FTP traffic to network 192.168.166.18/29 from any host will be denied. Answer: D Explanation: By default access list is having implicit deny statement at the end. In this example there is no permit statement, so it will deny all traffic exiting E0 Interface. Incorrect answers

A: It will deny FTP and Telnet Traffic B,C,E: It will deny all traffic in addition to the condition mentioned in the answer. Because there is no permit statement at the end.

QUESTION 27 What are the characteristic of link state routing protocols? (Choose all that apply.)

A. The exchange of advertisement is triggered by a change in the network.

B. All routers exchange routing tables with each other in a multipoint network.

C. Packets are routed based upon the shortest path to the destination.

D. Paths are chosen depending on the cost efficiency factor.

E. Every router in an OSPF area is capable of representing the entire network topology.

F. Only the designated router in an OSPF area can represent the entire network topology. Answer: A C E Explanation: Open Shortest Path First

• Each router discovers its neighbors on each interface. The list of neighbors is kept in a neighbor table.
• Each router uses a reliable protocol to exchange topology information with its neighbors.
• Each router places the learned topology information into its topology database.
• Each router runs the SPF algorithm against its own topology database.
• Each router runs the SPF algorithm against its own topology database to calculate the best routes to each subnet in the database.
• Each router places the best roué to each subnet into the IP routing table. The following list points out some of the key features of OSPF:
• Converges very quickly - from the point of recognizing a failure, it often can converge in less than 10 seconds.
• Supports VLSM.
• Uses short Hello messages on a short regular interval, with the absence of hello messages indicating that a neighbor is no longer reachable.
• Sends partial updates when link status changes, and floods full updates every 30 minutes. The flooding, however, does not happened all at once, so the overhead s minimal.
• Uses cost for the metric. Reference: CCNA Self-Study CCNA INTRO exam certification Guide (Cisco press, ISBN 1-58720-094-5) Page 417

QUESTION 28 You use multiple access lists when configuring it on an interface of a Cisco router. Which of the following statements are valid?

A. Application of up to three access lists per protocol to a single interface.

B. No more than two access lists per interface.

C. One access list may be configured per direction for each Layer 3 protocol configured on an interface.

D. The maximum number allowed varies due to RAM availability in the router.

E. An infinite number of access lists that can be applied to an interface, from most specific to most general.

F. Cisco IOS allows only one access list to an interface. Answer: C

A. Ethernet

B. PPP

C. Token Ring

D. HDLC

E. Frame Relay

F. POTS Answer: B, D E Explanation: WAN data-link protocols used on point-to-point serial Links provide the basic function of data delivery across that one link. The two most popular WAN data-link protocols are High-Level Data Link Control (HDLC) and PPP. Reference: CCNA Self-Study CCNA ICND exam certification Guide (Cisco press, ISBN 1-58720-083-X) Page
