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

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
You connect a new Cisco Catalyst 3750-X switch to the LAN that is configured to use an NTP
server. You want the new switch to automatically obtain its time from the NTP server.
You manually configure the system clock and then issue the ntp server 1.1.1.1 command on the
new switch.

Disable NTP authentication
Nothing; the basic configuration is complete
Reconfigure the NTP packet source IP address
Disable the NTP broadcast service
