CCNA 3 v6.0 (Scaling Networks v6) Chapter 2: Scaling VLANs: Check Your Understanding Questions Answers
1. Which statement is true when VTP is configured on a switched network that incorporates VLANs?
- VTP adds to the complexity of managing a switched network.
- VTP allows a switch to be configured to belong to more than one VTP domain.
- VTP dynamically communicates VLAN changes to all switches in the same VTP domain.
- VTP is only compatible with the 802.1Q standard.
2. What are two features of VTP client mode operation? (Choose two.)
- VTP clients can add VLANs of local significance.
- VTP clients can forward VLAN information to other switches in the same VTP domain.
- VTP clients can only pass VLAN management information without adopting
- VTP clients can forward broadcasts out all ports with no respect to VLAN information.
- VTP clients are unable to add VLANs.
3. What does a client mode switch in a VTP management domain do when it receives a summary advertisement with a revision number higher than its current revision number?
- It deletes the VLANs not included in the summary advertisement.
- It increments the revision number and forwards it to other switches.
- It issues an advertisement request for new VLAN information.
- It issues summary advertisements to advise other switches of status changes.
- It suspends forwarding until a subset advertisement update arrives.
4. What causes a VTP-configured switch to issue a summary advertisement?
- A five-minute update timer has elapsed.
- A new host has been attached to a switch in the management domain.
- A port on the switch has been shut down.
- The switch is changed to transparent mode.
5. Which three VTP parameters must be identical on all switches to participate in the same VTP domain? (Choose three.)
- Domain name
- Domain password
- Revision number
- Version number
6. Which two statements describe VTP transparent mode operation? (Choose two.)
- Transparent mode switches can add VLANs of local significance only.
- Transparent mode switches can adopt VLAN management changes that are received from other switches.
- Transparent mode switches can create VLAN management information.
- Transparent mode switches originate updates about the status of their VLANS and inform other switches about that status.
- Transparent mode switches pass any VLAN management information they receive to other switches.
7. Which two statements are true about the implementation of VTP? (Choose two.)
- Switches must be connected via trunks.
- Switches that use VTP must have the same switch name.
- The VTP domain name is case sensitive.
- The VTP password is mandatory and case sensitive.
- Transparent mode switches cannot be configured with new VLANs.
8. A network administrator is replacing a failed switch with a switch that was previously on the network. What precautionary step should the administrator take on the replacement switch to avoid incorrect VLAN information from propagating through the network?
- Change all the interfaces on the switch to access ports.
- Change the VTP domain name.
- Change the VTP mode to client.
- Enable VTP pruning.
9. Which two events cause the VTP revision number on a VTP server to change? (Choose two.)
- Adding VLANs
- Changing interface VLAN designations
- Changing the switch to a VTP client
- Changing the VTP domain name
- Rebooting the switch
10. How are VTP messages sent between switches in a domain?
- Layer 2 broadcast
- Layer 2 multicast
- Layer 2 unicast
- Layer 3 broadcast
- Layer 3 multicast
- Layer 3 unicast
11. A router has two FastEthernet interfaces and needs to connect to four VLANs in the local network. How can this be accomplished using the fewest number of physical interfaces without unnecessarily decreasing network performance?
- Add a second router to handle the inter-VLAN traffic.
- Implement a router-on-a-stick configuration.
- Interconnect the VLANs via the two additional FastEthernet interfaces.
- Use a hub to connect the four VLANS with a FastEthernet interface on the router.
12. What distinguishes traditional legacy inter-VLAN routing from router-on-a-stick?
- Traditional routing is only able to use a single switch interface, while routeron-a-stick can use multiple switch interfaces.
- Traditional routing requires a routing protocol, while router-on-a-stick needs to route only directly connected networks.
- Traditional routing uses one port per logical network, while router-on-a-stick uses subinterfaces to connect multiple logical networks to a single router port.
- Traditional routing uses multiple paths to the router and therefore requires STP, while router-on-a-stick does not provide multiple connections and therefore eliminates the need for STP.
13. What two statements are true regarding the use of subinterfaces for inter-VLAN routing? (Choose two.)
- Fewer router Ethernet ports are required than in traditional inter-VLAN routing.
- The physical connection is less complex than in traditional inter-VLAN routing.
- More switch ports are required than in traditional inter-VLAN routing.
- Layer 3 troubleshooting is simpler than with traditional inter-VLAN routing.
- Subinterfaces have no contention for bandwidth.
14. What is important to consider while configuring the subinterfaces of a router when implementing inter-VLAN routing?
- The IP address of each subinterface must be the default gateway address for each VLAN subnet.
- The no shutdown command must be run on each subinterface.
- The physical interface must have an IP address configured.
- The subinterface numbers must match the VLAN ID number.
15. What steps must be completed in order to enable inter-VLAN routing using router-on-a-stick?
- Configure the physical interfaces on the router and enable a routing protocol.
- Create the VLANs on the router and define the port membership assignments on the switch.
- Create the VLANs on the switch to include port membership assignment and enable a routing protocol on the router.
- Create the VLANs on the switch to include port membership assignment and configure subinterfaces on the router matching the VLANs.
