Correct Answer: Physical layer
Explanation:
Hubs regenerate electrical signals, which are specified at the Physical layer.
Correct Answer: ICMP
Explanation:
ICMP is the protocol at the Network layer that is used to send echo requests and replies.
Correct Answer: 128 bits
Explanation:
An IPv6 address is 128 bits long.
Correct Answer: NCP
Explanation:
Network Control Protocol is used to help identify the Network layer protocol used in the packet.
Correct Answer: line vty 0 4
Explanation:
The command
line vty 0 4 places you in a prompt that will allow you to set or change your Telnet password.
Correct Answer: A
Explanation:
Class A addressing provides 24 bits for host addressing.
Correct Answer: VTP is used to send VLAN information to switches in a configured VTP domain.
Explanation:
Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunking Protocol (VTP) is used to propagate VLAN information across a trunk link.
Correct Answer: 12
Explanation:
Layer 2 switching creates individual collision domains.
Correct Answer: So different networks could communicate.
Explanation:
The primary reason the OSI model was created was so that different networks could inter-operate.
Correct Answer: copy running-config startup-config
Explanation:
The command to back up the configuration on a router is
copy running-config startup-config.
