Cisco Cert Prep 1

What are three characteristic of the CSMA/CD process? (Choose three.)

1.)After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired. 2.)A deice listens and waits until the media is not busy before transmitting. 3.)All of the devices on a segment see data that passes on the network medium.

Which three layers of the IOS model map to the application layer of the TCP/IP model (Choose three.)

1.)Application 2.)Presentation 3.)Session

An Administrator wants to replace the configuration file on a Cisco router by loading new configuration file from a TFTP server. What two things does the administrator need to know before preforming this task? (Choose two.)

1.)Name of the configuration file that is currently stored on the router. 2.)Name of the configuration file that is stored on the TFTP server.

R2# show ntp associations detail 192.168.1.2 configured, authenticated, our_master, sane, valid, stratum 3 <output omitted> Refer to the exhibit. Router 1 and Router 2 are connected via a serial link. One router is configured as the NTP master, and the other is a NTP client. Which two pieces of information can be obtained from the partial output of the "Show ntp associations detail" command on R2? (Choose two.)

1.)The IP address of R1 is 192.168.1.2 2.)Router R1 is the master, and R2 is the client

Which two things should a network administrator modify on a router to preform password recovery (Choose two.)

1.)The configuration register value 2.) the startup configuration file

Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)

1.)The source port field identifies the running application or service that will handle data returning to the PC. 2.)The UDP destination port number identifies the application or service on the server which will handle the data. 3.)UDP segments are encapsulated within IP packets for transport across the network.

Which three statements characterize UDP? (Choose three.)

1.)UDP relies on application layer protocols for error detection. 2.)UDP provides basic connection less transport layer functions. 3.)UDP is a low overhead protocol that does not provide sequencing or flow control mechanisms.

A network administrator has been allocated the IPv4 10.10.240.0/20 block of addresses for a LAN. Two devices on two different, but contiguous, subnets on the LAN have been assigned the addresses 10.10.247.1/21 and 10.10.248.10/24, respectively. THe administrator has to create a third subnet from the remaining address range. To optimize the use of this address space, the new subnet will follow on directly from the existing subnets. What is the first available host address in the next available subnet?

10.10.249.1

Router1# show access-lists standard IP access list TRAFFIC-CONTROL 10 permit 172.23.0.0, wildcard bits 0.0.255.255 20 deny any Refer to the exhibit. A network administrator needs to add an ACE to the TRAFFIC-CONTROL ACL that will deny IP traffic from the subnet 172.23.16.0/20. Which ACE will meet this requirement?

5 deny 172.23.16.0 0.0.15.255

What effect does the "Default-Information Originate" command have on a Cisco Router that is configured for RIP?

Any default static route that is configured on the router will propagate to other adjacent routers.

How will a router handle static routing differently if Cisco Express Forwarding is disabled?

Ethernet multiaccess interfaces will require fully specified static routes to avoid routing inconsistencies.

Which statement describes the Cisco License Manager?

It is a free, standalone software application for deploying Cisco Software License across the network.

After a license has been purchased and installed, what is the next step that is required before it is activated?

Reboot the Router

A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?

The MAC address of the default gateway.

Which address prefix range is reserved for IPv4 multicast? a.)127.0.0.0-127.255.255.255 b.)169.254.0.0-169.254.255.255 c.)240.0.0.0-254.255.255.255 d.)224.0.0.0-239.255.255.255

d.)224.0.0.0-239.255.255.255
