• The adjacency table

• The ARP table

• The VLAN table

• The FIB table

• The CAM table

Which of the following VLANs is used by DTP to negotiate a trunk link when 802.1Q encapsulation is configured on the interface?

• The native VLAN

• 1

• 0

• 4094

Which of the following subnet addresses is most appropriate for a point-to-point link between two Routers ?

• 192.168.0.192/26

• 192.168.0.128/30

• 192.168.0.128/25

• 192.168.0.130/30

• 192.168.0.0/30

Which of the following Application layer protocols use UDP for unsynchronized, connectionless data transfer? (Choose two)

• SMTP

• HTTP

• FTP

• TFTP

• SNMP

You want to configure SSH for incoming VTY connections on a new router. The router is running a K9 IOS image but has not yet been configured with a host name, a domain name, or an RSA key pair. In addition, the VTY lines are not yet configured to accept incoming SSH connections

You issue the crypto key generate rsa command from global configuration mode

Which of the following messages will you most likely receive?

• Please define a hostname other than Router.

• Please create RSA keys to enable SSH.

• The name for the keys will be:

• Please enable SSH as a transport mode

• Please define a domain-name first.

You issue the following commands on a Cisco router named RouterA

enable password !abcu$3r!

enable secret abc4dm!n

line console 0

password abc4dm!n

line vty 0 15

login

password abcu$3r

service password-encryption

Another user has been asked to examine the running configuration on RouterA but not make any configuration changes. The user connects to RouterA by using Telnet.

Which of the following will the user require in order to perform this task?

• The enable secret password and the console password

• The console password alone

• The VTY line password alone

• The enable password and the console password

• The enable secret password and the VTY line password

In a two-tier network design, which layers are combined together?

• aggregation and access

• core, distribution, and access

• Core and distribution

• core and access

• distribution and access

Which of the following is enabled on a Cisco router when you issue the ntp server command from global configuration mode?

• broadcast client mode

• server mode

• authentication

• static client mode

Which of the following networks is not defined by RFC 1918?

• 10.1.1.0

• 192.168.111.0

• 10.16.1.0

• 172.172.1.0

• 172.20.1.0

You issue the show running-config command on RouterA and receive the following partial

output:

interface FastEthernet0/0

ip address 192.168.18.33 255.255.255.240

HostA is on the same physical network as the FastEthernet 0/0 interface of RouterA.

Which IP address should you configure on HostA to ensure that the host can communicate with

the rest of the network?

• 192.168.18.32/28

• 192.168.18.48/28

• 192.168.18.46/28

• 192.168.18.16/28
