Correct Answer: 5
Explanation:
Cisco routers, if they do not have the Enterprise edition of the IOS, will default to 5 simultaneous Telnet sessions.
Correct Answer: 10xxxxxx
Explanation:
The range of a Class B network address is
128-191. This makes our binary range
10xxxxxx.
Correct Answer: ARP
Explanation:
Address Resolution Protocol (ARP) is used to find the hardware address from a known IP address.
Correct Answer: Class C
Explanation:
A Class C network address has only 8 bits for defining hosts: 2
8 - 2 = 254.
Correct Answer: 1 and 2
Explanation:
A client that sends out a DHCP Discover message in order to receive an IP address sends out a broadcast at both layer 2 and layer 3. The layer 2 broadcast is all Fs in hex, or
FF:FF:FF:FF:FF:FF. The layer 3 broadcast is
255.255.255.255, which means all networks and all hosts. DHCP is connectionless, which means it uses User Datagram Protocol (UDP) at the Transport layer, also called the Host-to-Host layer.
Correct Answer: Ctrl+C
Explanation:
You can exit setup mode at any time by using the keystroke
Ctrl+C.
Correct Answer: Setup mode
Explanation:
If you delete the startup-config and reload the router, the router will automatically enter setup mode. You can also type
setup from privileged mode at any time.
Correct Answer: service password-encryption
Explanation:
The command
service password-encryption, from global configuration mode, will encrypt the passwords.
Correct Answer: erase start
Explanation:
The
erase startup-config command erases the contents of NVRAM and will put you in setup mode if the router is restarted.
Correct Answer: The administrator has the interface shut down.
Explanation:
If an interface is shut down, the
show interface command will show the interface as administratively shut down. (It is possible that no cable is attached, but you can't tell that from this message.)
