- Question
A switch has been configured configured for three different VLANs : VLAN2, VLAN3 and VLAN4. A router has been added to provide communication between the VLANs. What minimum type of interface necessary on the router if only one connection is to be made between the router and the switch?
Options- A. 10Mbps Ethernet
- B. 56Kbps Serial
- C. 100Mbps Ethernet
- D. 1Gbps Ethernet
- Correct Answer
- 100Mbps Ethernet
ExplanationAlthough 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.
- 1. You want to improve network performance by increasing the bandwidth available to hosts and limit the size of the broadcast domains. Which of the following options will achieve this goal?
Options- A. Managed hubs
- B. Bridges
- C. Switches
- D. Switches configured with VLANs Discuss
- 2. Which switching technology reduces the size of a broadcast domain?
Options- A. ISL
- B. 802.1Q
- C. VLANs
- D. STP Discuss
- 3. Which Cisco 802.1d extension stops BPDU from being transmitted out a port? Discuss
- 4. Which proprietary Cisco STP extensions would put a switch port into err-disabled if a BPDU is received on this port? Discuss
- 5. You have two switches connected together with two crossover cables for redundancy, and STP is disabled. Which of the following will happen between the switches?
Options- A. The routing tables on the switches will not update
- B. The MAC forward/;filter table will not update on the switch
- C. Broadcast storms will occur on the switched network
- D. The switches will automatically load-balance between the two links Discuss
- 6. Which of the following commands sets a trunk port on a 2960 switch?
Options- A. truck on
- B. truck all
- C. switchport trunk on
- D. switchport mode trunk Discuss
- 7. You connect a host to a switch port, but the new host cannot log into the server that is plugged into the same switch. What could the problem be?
Options- A. The router is not configured for the new host
- B. The VTP configuration on the switch is not updated for the new host
- C. The host has an invalid MAC address
- D. The switch port the host is connected to is not configured with the correct VLAN membership Discuss
- 8. What is frame tagging? Discuss
- 9. What type of Cisco tagging information allows VLANs to be multiplexed over a trunk link through an external encapsulation method? Discuss
- 10. Which of the following is an example of a standard IP access list?
Options- A. access - list 110 permit host 1.1.1.1
- B. access - list 1 deny 172 . 16 . 10 . 1 0 . 0 . 0 . 0
- C. access - list 1 permit 172 . 16 . 10 . 1 255 . 255 . 0 . 0
- D. access - list standard 1 . 1 . 1 . 1 Discuss

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: PortFast
Correct Answer: BPDUGuard
Correct Answer: Broadcast storms will occur on the switched network
Explanation:
If spanning tree is disabled on a switch and you have redundant links to another switch, broadcast stroms will occur, among other possible problems.
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: 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: Frame identification (frame tagging) uniquely assigns a user-defined ID to each frame This is sometimes reffered to as a VLAN ID or color
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.
