To disable CDP on a particular interface, use the no cdp enable command in interface configuration mode.

What is the benefit of wireless as a media choice?

  1. more host mobility

  2. lower security risks

  3. reduced susceptibility to interference

  4. less impact of the surroundings on the effective coverage area


Correct Option: A

A network administrator uses the CLI to enter a command that requires several parameters. The switch responds with "% Incomplete command". The administrator cannot remember the missing parameters. What can the administrator do to get the parameter information?

  1. append ? to the last parameter

  2. append a space and then ? to the last parameter

  3. use Ctrl-P to show a parameter list

  4. use the Tab key to show which options are available


Correct Option: B

As a WAN engineer, it is your responsibility to enable port security on your company's Cisco Catalyst switch. Which of the following answers correctly states the function of enabling port security on this switch?

  1. Limits that hours of operation for this switch

  2. Allows only administrator passwords

  3. Limits all port traffic through this switch

  4. Limits the number of MAC addresses that can be serviced from a port


Correct Option: D
Explanation:

Port Security is a feature that, when enabled, limits the number of MAC addresses associated with a port. In other words, there is a preset limit to the number of sources that can access or forward frames into the switch.

Refer to the exhibit. Hosts B and C attempt to transmit a frame at the same time, but a collision occurs. Which hosts will receive the collision jamming signal?

  1. All hosts that are shown

  2. Only hosts B and C

  3. Only hosts A, B, and C

  4. Only hosts A, B, C, and D

  5. Only hosts A, D, E, and F


Correct Option: C

While configuring a new switch, a network administrator configures the switch as an HTTP server. What benefits does this configuration provide?

  1. This allows the switch to host web pages for the network.

  2. This allows remote VPN connections to the switch over the Internet.

  3. This is required if a web server or web farm is attached to the switch.

  4. This allows web-based configuration tools to be used with the switch.


Correct Option: D

Which WAN technology uses a fixed payload of 48 bytes and is transported across both switched and permanent virtual circuits?

  1. ATM

  2. ISDN

  3. Frame Relay

  4. metro Ethernet


Correct Option: A

Which network command or set of commands will cause OSPF to be enabled for any R1 interface connected to the exhibited subnets?

  1. R1(config-router)# network 10.0.0.0 0.0.0.0 area 0

  2. R1(config-router)# network 10.1.0.0 0.0.0.255 area 0

  3. R1(config-router)# network 10.1.1.0 0.0.0.255 area 0

  4. R1(config-router)# network 10.1.2.4 0.0.0.3 area 0

  5. R1(config-router)# network 10.1.0.0 0.0.0.255.255 area 0


Correct Option: B

Which of the following options is true regarding OSPF?

  1. OSPF is an exterior gateway protocol (EGP).

  2. OSPF routing updates do not include the subnet masks.

  3. OSPF routing updates always contain the entire routing table.

  4. OSPF supports variable-length subnet masks.


Correct Option: D
Explanation:

OSPF is a classless interior gateway protocol (IGP) which supports VLSM, hence includes the subnet masks in the routing updates. OSPF routers exchange the state of their links (interfaces) by sending incremental updates, not the entire routing table.

A network administrator needs to keep the user ID, password, and session contents private when establishing remote CLI connectivity with a router to manage it. Which of the following access methods should be chosen?

  1. Telnet

  2. Console

  3. AUX

  4. SSH


Correct Option: D

If NVRAM lacks boot system commands, where does the router look for the Cisco IOS by default?

  1. ROM

  2. RAM

  3. Flash

  4. Bootstrap


Correct Option: C
Explanation:

Flash memory - Either an EEPROM or a PCMCIA card, Flash memory stores fully functional IOS images and is the default location where the router gets its IOS at boot time. Flash memory also can be used to store any other files, including configuration files.

Refer to the exhibit. All routers are configured to use the EIGRP routing protocol with default settings, all routes are advertised on all routers, and the network is fully converged. Which path will the data take to travel between 172.16.1.0/24 and 192.168.100.0/24?

  1. It will travel via A, B, and C.

  2. It will travel via A, F, E, D, and C.

  3. It will travel via A, G, H, and C.

  4. The traffic will be load-balanced on all paths.


Correct Option: B

Which of the following options is used by the Logical Link Control to communicate with the Network Layer?

  1. MAC Address

  2. Source Service Access Points

  3. Port Numbers

  4. Flow Control


Correct Option: B
Explanation:

The Logical Link Control communicates with the Network Layer using Source Service Access Points.

Refer to the exhibit. Users on the Internal LAN are unable to connect to the www server. The network administrator pings the server and verifies that NAT is functioning correctly. Which OSI layer should the administrator begin to troubleshoot next?

  1. physical

  2. data link

  3. network

  4. application


Correct Option: D

Refer to the exhibit. An administrator has configured two access lists on R1. The list inbound on the serial interface is named Serial and the list inbound on the LAN interface is named LAN. What affect will be produced by the access control lists?

  1. PC1 will be able to telnet to PC3.

  2. R3 will not be able to communicate with PC1 and PC3.

  3. PC3 cannot telnet to R3 and cannot communicate with PC1.

  4. PC1 will not be able to telnet to R3 and PC3 will not be able to communicate with PC1.


Correct Option: D

What is a function of the data link layer?

  1. provides the formatting of data

  2. provides end-to-end delivery of data between hosts

  3. provides delivery of data between two applications

  4. provides for the exchange data over a common local media


Correct Option: D

Which of the following statements is true when VTP is configured on a switched network that incorporates VLANs?

  2. VTP adds to the complexity of managing a switched network.

  3. VTP allows a to be configured to belong to more than one VTP domain.
