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: DNS
Explanation:
DNS uses TCP for zone exchanges between servers and UDP when a client is trying to resolve a hostname to an IP address.
Correct Answer: enable secret Cisco
Explanation:
The enable secret password is case sensitive, so the second option is wrong. To set the
enable secret <password>, use the
enable secret <password> command from global configuration mode.
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.
