- Correct Answer
- Frame identification (frame tagging) uniquely assigns a user-defined ID to each frame This is sometimes reffered to as a VLAN ID or color

Options- A. 10Mbps Ethernet
- B. 56Kbps Serial
- C. 100Mbps Ethernet

Correct Answer: The switch port the host is connected to is not configured with the correct VLAN membership
Explanation:
This question is a little Vague, but the best answer is that the VLAN membership for the port is not configured
Correct Answer: switchport mode trunk
Explanation:
To set a switch port to trunk mode, which allows the data of all VLAN information to pass down the link, use the switchport mode trunk command.
Correct Answer: 100Mbps Ethernet
Explanation:
Although you can use either 100Mbps or 1Gbps Ethernet, the 100Mbps is necessary at a minimum and is the best answer to this question. You need to trunk the link from the switch to the router to make this connection work with inter-VLAN communication.
Correct Answer: Switches configured with VLANs
Explanation:
By creating and implementing VLANs in your switched network, you can break up broadcast domains at layer2. 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: Inter-Switch Link (ISL)
Correct Answer: access - list 1 deny 172 . 16 . 10 . 1 0 . 0 . 0 . 0
Explanation:
Standard IP access lists use the numbers 1 - 99 and 1300 - 1999 and filter based on source IP address only. Option C is incorrect because the mask must be in wildcard format.
Correct Answer: access - list 10 deny 192.168.160.0 0.0.31.255
Explanation:
The range of 192.168.160.0 to 192.168.191.0 is a block size of 32. The network address is 192.168.160.0 and the mask would be 255.255.224.0, which for an access list must be a wildcard format of 0.0.31.255 . The 31 is used for a block size of 32. The wildcard is always one less than the block size.
Correct Answer: show ip interface
Explanation:
Of the available choices only the show ip interface command will tell you which interfaces have access lists applied. show access - lists will not show you which interfaces have an access list applied.
Correct Answer: access - list 100 deny tcp any 192.168.10.0 0.0.0.255 eq 23
Explanation:
The extended access list ranges are 100 - 199 and 2000 - 2699, so the access-list number of 100 is valid. Telnet uses TCP, so the protocol TCP is valid. Now you just need to look for the source and destination address. only the third option has the correct sequence of parameters. Option B may work, but the question specifically states "only" to network 192.168.10.0, and the wildcard in option B is too broad.
