Correct Answer: Stops an interface from sending periodic dynamic updates but not from receiving updates.
Explanation:
The
passive command, short for passive-interface, stops regular updates from being sent out an interface. However, the interface can still receive updates.
Correct Answer: ICMP
Explanation:
ICMP is the protocol at the Network layer that is used to send messages back to an originating router.
Correct Answer: 192.168.168.129-190
Explanation:
256 - 192 = 64. 64 + 64 = 128. 128 + 64 = 192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129-190.
Correct Answer: 3 and 4
Explanation:
VTP is not right because it has nothing to do with trunking except that it sends VLAN information across a trunk link. 802.1Q and ISL are used to configure trunking on a port.

Explanation:
VLANs break up broadcast domains at layer 2.
Correct Answer: show access-lists
Explanation:

show access-lists command.
Correct Answer: show ip interface
Explanation:
The
show ip interface command will show you if any outbound or inbound interfaces have an access list set.
Correct Answer: 1
Explanation:
By default, switches break up collision domains but are one large broadcast domain.
Correct Answer: copy tftp flash
