- Question
What does the passive command provide to dynamic routing protocols?
Options- A. Stops an interface from sending or receiving periodic dynamic updates.
- B. Stops an interface from sending periodic dynamic updates but not from receiving updates.
- C. Stops the router from receiving any dynamic updates.
- D. Stops the router from sending any dynamic updates.
- Correct Answer
- Stops an interface from sending periodic dynamic updates but not from receiving updates.
ExplanationThe passive command, short for passive-interface, stops regular updates from being sent out an interface. However, the interface can still receive updates. - 1. Which of the following is true regarding VLANs?
Options- A. You must have at least two VLANs defined in every Cisco switched network.
- B. All VLANs are configured at the fastest switch and, by default, propagate this information to all other switches.
- C. You should not have more than 10 switches in the same VTP domain.
- D. VTP is used to send VLAN information to switches in a configured VTP domain. Discuss
- 2. A switch has been configured for three different VLANs: VLAN2, VLAN3, and VLAN4. A router has been added to provide communication between the VLANs. What type of interface is 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 Discuss
- 3. 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
- 4. Which of the following modes are valid when a switch port is used as a VLAN trunk?
- Blocking
- Dynamic auto
- Dynamic desirable
- Nonegotiate
- Access
- Learning
Options- A. 1, 2 and 6
- B. 2, 3 and 4
- C. 4, 5 and 6
- D. 2, 4, and 5 Discuss
- 5. Which of the following are advantages of using NAT?
- Translation introduces switching path delays.
- Conserves legally registered addresses.
- Causes loss of end-to-end IP traceability.
- Increases flexibility when connecting to the Internet.
- Certain applications will not function with NAT enabled.
- Reduces address overlap occurrence.
Options- A. 1, 3 and 4
- B. 3, 5 and 6
- C. 5 and 6
- D. 2, 4 and 6 Discuss

- Gateway(config)# ip route 0.0.0.0 0.0.0.0 206.143.5.2
- Gateway(config)# router rip
- Gateway(config-router)# network 206.143.5.0
- Gateway(config-router)# network 206.143.5.0 default
Options- A. 1 only

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 Trunk Protocol (VTP) is used to propagate VLAN information across a trunked link.
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 layer 2. For hosts on different VLANs to communicate, you must have a router or layer 3 switch.
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: 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: 1 and 4
Explanation:
There are actually three different ways to configure the same default route, but only two are shown in the answer. First, you can set a default route with the
0.0.0.0 0.0.0.0 mask and then specify the next hop, as in option A. Or you can use
0.0.0.0 0.0.0.0 and use the exit interface instead of the next hop. Finally, you can use option D with the
ip default-network command.
Correct Answer: LCP
Explanation:
Link Control Protocol in the PPP stack provides dynamic addressing, authentication, and multilink.
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: UDP
Explanation:
User Datagram Protocol is a connection network service at the Transport layer, and DHCP uses this connectionless service.
Correct Answer: copy tftp flash
Explanation:
The
copy tftp flash command places a new file in flash memory, which is the default location for the Cisco IOS in Cisco routers.
