- Question
You have an interface on a router with the IP address of 192.168.192.10/29. Including the router interface, how many hosts can have IP addresses on the LAN attached to the router interface?
Options- A. 6
- B. 8
- C. 30
- D. 32
- Correct Answer
- 6
ExplanationA /29 (255.255.255.248), regardless of the class of address, has only 3 host bits. Six hosts is the maximum number of hosts on this LAN, including the router interface. - 1. Suppose that you have a customer who has a central HQ and six branch offices. They anticipate adding six more branches in the near future. They wish to implement a WAN technology that will allow the branches to economically connect to HQ and you have no free ports on the HQ router. Which of the following would you recommend?
Options- A. PPP
- B. HDLC
- C. Frame Relay
- D. ISDN Discuss
- 2. The Acme Corporation is implementing dial-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols, needs authentication of users connecting to the network, and since some calls will be long distance, needs callback support. Which of the following protocols is the best choice for these remote services?
Options- A. 802.1
- B. Frame Relay
- C. HDLC
- D. PPP
- E. PAP Discuss
- 3. You save the configuration on a router with the copy running-config startup-config command and reboot the router. The router, however, comes up with a blank configuration. What can the problem be?
Options- A. You didn't boot the router with the correct command.
- B. NVRAM is corrupted.
- C. The configuration register setting is incorrect.
- D. The newly upgraded IOS is not compatible with the hardware of the router. Discuss
- 4. Which WAN encapsulations can be configured on an asynchronous serial connection?
- PPP
- ATM
- HDLC
- SDLC
- Frame Relay
Options- A. 1 and 2
- B. 2 and 4
- C. 3, 4 and 5
- D. All of the above Discuss
- 5. When setting up Frame Relay for point-to-point subinterfaces, which of the following must not be configured?
Options- A. The Frame Relay encapsulation on the physical interface
- B. The local DLCI on each subinterface
- C. An IP address on the physical interface
- D. The subinterface type as point-to-point Discuss
- 6. Which command will display the CHAP authentication process as it occurs between two routers in the network?
Options- A. show chap authentication
- B. show interface serial 0
- C. debug ppp authentication
- D. debug chap authentication Discuss
- 7. What is the maximum data rate for the 802.11b standard?
Options- A. 6Mbps
- B. 11Mbps
- C. 22Mbps
- D. 54Mbps Discuss
- 8. Which of the following are unique characteristics of half-duplex Ethernet when compared to full-duplex Ethernet?
- Half-duplex Ethernet operates in a shared collision domain.
- Half-duplex Ethernet operates in a private collision domain.
- Half-duplex Ethernet has higher effective throughput.
- Half-duplex Ethernet has lower effective throughput.
Options- A. 2 only
- B. 1,2 and 3
- C. 1 and 4
- D. 4 only Discuss
- 9. Which of the following is considered to be the destination host after translation?
Options- A. Inside local
- B. Outside local
- C. Inside global
- D. Outside global Discuss
- 10. Which of the following statement is true?
Options- A. A switch creates a single collision domain and a single broadcast domain. A router creates a single collision domain.
- B. A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain.
- C. A switch creates a single collision domain and separate broadcast domains. A router provides a separate broadcast domain as well.
- D. A switch creates separate collision domains and separate broadcast domains. A router provides separate collision domains. Discuss
More questions
Correct Answer: Frame Relay
Explanation:
The key is "there are no free ports" on your router. Only Frame Relay can provide a connection to multiple locations with one interface, and in an economical manner no less.
Correct Answer: PPP
Explanation:
PPP is your only option, as HDLC and Frame Relay do not support these types of business requirements. PPP provides dynamic addressing, authentication using PAP or CHAP, and callback services.
Correct Answer: The configuration register setting is incorrect.
Explanation:
If you save a configuration and reload the router and it comes up either in setup mode or as a blank configuration, chances are you have the configuration register setting incorrect.
Correct Answer: 1 and 2
Explanation:
Please do not freak out because ATM is an answer to this question. ATM is not covered in depth on the CCNA exam. PPP is mostly used for dial-up (async) services, but ATM could be used as well, though it typically is not used anymore since PPP is so efficient.
Correct Answer: An IP address on the physical interface
Explanation:
It is very important to remember when studying the CCNA exam objectives, and when configuring Frame Relay with point-to-point subinterfaces, that you do not put an IP address on the physical interface.
Correct Answer: debug ppp authentication
Explanation:
The command
debug ppp authentication will show you the authentication process that PPP uses between point-to-point connections.
Correct Answer: 11Mbps
Explanation:
The IEEE 802.11b standard provides a maximum data rate of up to 11Mbps.
Correct Answer: 1 and 4
Explanation:
Unlike full duplex, half-duplex Ethernet operates in a shared collision domain, and it has a lower effective throughput than full duplex.
Correct Answer: Outside global
Explanation:
The host on the global network after translation is considered to be an outside global host.
Correct Answer: A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain.
Explanation:
Switches break up collision domains, and routers break up broadcast domains.
