Refer to the exhibit. A network administrator is configuring access control to switch SW1. If the administrator has already logged into a Telnet session on the switch, which password is needed to access privileged EXEC mode? Enter configuration commands, one per line. end with CNTL/Z. SW1(config)# enable password letmein SW1(config)# enable secret secretin SW1(config)# line con 0 SW1(config-line)# password lineconin SW1(config-line)# login SW1(config-line)# exit SW1(config)# line vty 0 15 SW1(config-line)# password linevtyin SW1(config-line)# login SW1(config-line)# end SW1#

Refer to the exhibit. A network administrator is configuring access control to switch SW1. If the administrator uses a console connection to connect to the switch, which password is needed to access user EXEC mode? Enter configuration commands, one per line. end with CNTL/Z. SW1(config)# enable password letmein SW1(config)# enable secret secretin SW1(config)# line con 0 SW1(config-line)# password lineconin SW1(config-line)# login SW1(config-line)# exit SW1(config)# line vty 0 15 SW1(config-line)# password linevtyin SW1(config-line)# login SW1(config-line)# end SW1#
A router along the path did not have a route to the destination.
Refer to the exhibit. An administrator is testing connectivity to a remote device with the IP address 10.1.1.1. What does the output of this command indicate? Switch# ping 10.1.1.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds: UUUUU Success rate is 0 percent (0/5) Connectivity to the remote device was successful. A router along the path did not have a route to the destination. A ping packet is being blocked by a security device along the path. The connection timed out while waiting for a reply from the remote device.
192.168.10.128
Refer to the exhibit. Consider the IP address of 192.168.10.0/24 that has been assigned to a high school building. The largest network in this building has 100 devices. If 192.168.10.0 is the network number for the largest network, what would be the network number for the next largest network, which has 40 devices? 192.168.10.0 192.168.10.128 192.168.10.192 192.168.10.224 192.168.10.240
The delimiting character appears in the banner message.
Refer to the exhibit. From global configuration mode, an administrator is attempting to create a message-of-the-day banner by using the command banner motd V Authorized access only! Violators will be prosecuted! V When users log in using Telnet, the banner does not appear correctly. What is the problem? Authorized access only! Router> The banner message is too long. The delimiting character appears in the banner message. The symbol "!" signals the end of a banner message. Message-of-the-day banners will only appear when a user logs in through the console port.
BB:BB:BB:BB:BB:BB
Refer to the exhibit. If host A sends an IP packet to host B, what will the destination address be in the frame when it leaves host A? Host B MAC) DD:DD:DD:DD:DD:DD Host A IP) 172.168.10.99 RB MAC) CC:CC:CC:CC:CC:CC RA IP) 172.168.10.65 RA MAC) BB:BB:BB:BB:BB:BB Host A MAC) AA:AA:AA:AA:AA:AA
There is connectivity between this device and the device at 192.168.100.1. There are 4 hops between this device and the device at 192.168.100.1.
Refer to the exhibit. On the basis of the output, which two statements about network connectivity are correct?

default gateway address
Refer to the exhibit. The network administrator for a small advertising company has chosen to use the 192.168.5.96/27 network for internal LAN addressing. As shown in the exhibit, a static IP address is assigned to the company web server. However, the web server cannot access the Internet. The administrator verifies that local workstations with IP addresses that are assigned by a DHCP server can access the Internet, and the web server is able to ping local workstations. Which component is incorrectly configured? IP Address: 192.168.5.98 Subnet Mask: 255.255.255.224 Default Gateway: 192.168.5.1 Preferred DNS Server: 128.208.3.254
The administrator will be presented with the R1> prompt.
Refer to the exhibit. What will be the result of entering this configuration the next time a network administrator connects a console cable to the router and no additional commands have been entered? R1# config t R1(config)# enable password Cisco123 R1(config)# enable secret Cisco234 R1(config)# service password-encryption R1(config)# line con 0 R1(config-line)# password Cisco789 R1(config-line)# end R1# copy running-config startup-config R1# reload
They are globally unique. They are expressed as 12 hexadecimal digits.
What are two characteristics of Ethernet MAC addresses?
The computer receives an IP address that starts with 169.254
What is one indication that a Windows computer did not receive an IPv4 address from a DHCP server? The computer cannot ping 127.0.0.1. Windows displays a DHCP timeout message.
