Correct Answer: VTP
Explanation:
Virtual Trunk Protocol (VTP) is used to pass a VLAN database to any or all switches in the switched network. The three VTP modes are server, client, and transparent.
Correct Answer: 2, 3 and 4
Explanation:
The valid modes of a VLAN trunk on a switch are dynamic auto, dynamic desirable, trunk (on), and nonegotiate.
Correct Answer: By default, all VLANs are allowed on the trunk.
Explanation:
By default, all VLANs are allowed on the trunk link and you must remove by hand each VLAN that you don't want traversing the trunked link.
Correct Answer: Server
Explanation:
Only in server mode can you change VTP information on a switch.
Correct Answer: Switches configured with VLANs
Explanation:
By creating and implementing VLANs in your switched network, you can break up broadcast domains at layer 2. For hosts on different VLANs to communicate, you must have a router or layer 3 switch.
Correct Answer: VLANs
Explanation:
Virtual LANs break up broadcast domains in layer 2 switched internetworks.
Correct Answer: 2, 4 and 6
Explanation:
NAT is not perfect, but there are some advantages. It conserves global addresses, which allow us to add millions of hosts to the Internet without "real" IP addresses. This provides flexibility in our corporate networks. NAT can also allow you to use the same subnet more than once in the same network without overlapping networks.
Correct Answer: Outside local
Explanation:
The host on the global network before translation is considered to be an outside local host.
Correct Answer: debug ip nat
Explanation:
The command
debug ip nat will show you in real time the translations occurring on your router.
Correct Answer: Inside local
Explanation:
The host on the private network before translation is considered to be an inside local host.
