Refer to the exhibit.

A technician has configured the FastEthernet 0/1 interface on Sw11 as an access link in VLAN 1. Based on the output from the show vlan brief command issued on Sw12, what will be the result of making this change on Sw11?

1. A. Only the hosts in VLAN 1 on the two switches will be able to communicate with each other.
2. B. The hosts in all VLANs on the two switches will be able to communicate with each other.
3. C. Only the hosts in VLAN 10 and VLAN 15 on the two switches will be able to communicate with each other.
4. D. Hosts will not be able to communicate between the two switches.

Correct Answer: D
VLANs are local to each switch's database, and VLAN information is not passed between switches without implementing VLAN Trunk Protocol (VTP). Trunks carry traffic from all VLANs to and from the switch by default but, can be configured to carry only specified VLAN traffic. Trunk links are required to pass VLAN information between switches. So Sw11 port should be trunk not access port. Additionally, there are no ports assigned to VLAN 1.

Which three statements about HSRP operation are true? (Choose three.)

1. A. The virtual IP address and virtual MA+K44C address are active on the HSRP Master router.
2. B. The HSRP default timers are a 3 second hello interval and a 10 second dead interval.
3. C. HSRP supports only clear-text authentication.
4. D. The HSRP virtual IP address must be on a different subnet than the routers' interfaces on the same LAN.
5. E. The HSRP virtual IP address must be the same as one of the router's interface addresses on the LAN.
6. F. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.

Correct Answer: ABF

2. B. exstart state > exchange state > loading state > full state
3. C. exstart state > full state > loading state > exchange state
4. D. loading state > exchange state > full state > exstart state

It has become necessary to configure an existing serial interface to accept a second Frame Relay virtual circuit. Which of the following are required to solve this? (Choose three)

1. A. configure static frame relay map entries for each subinterface network.
2. B. remove the ip address from the physical interface
3. C. create the virtual interfaces with the interface command
4. D. configure each subinterface with its own IP address
5. E. disable split horizon to prevent routing loops between the subinterface networks
6. F. encapsulate the physical interface with multipoint PPP

Correct Answer: BCD
How To Configure Frame Relay Subinterfaces
http://www.orbit-computer-solutions.com/How-To-Configure-Frame-Relay- Subinterfaces.php
Step to configure Frame Relay subinterfaces on a physical interface:
1. Remove any network layer address (IP) assigned to the physical interface. If the physical interface has an address, frames are not received by the local subinterfaces.
2. Configure Frame Relay encapsulation on the physical interface using the encapsulation frame-relay command.
3. For each of the defined PVCs, create a logical subinterface. Specify the port number, followed by a period (.) and the subinterface number. To make troubleshooting easier, it is suggested that the subinterface number matches the DLCI number.
4. Configure an IP address for the interface and set the bandwidth.
5. Configure the local DLCI on the subinterface using the frame-relay interface-dlci command.
Configuration Example: R1>enable R1#configure terminal
R1(config)#interface serial 0/0/0 R1(config-if)#no ip address
R1(config-if)#encapsulation frame-relay R1(config-if)#no shutdown
R1(config-if)#exit
R1(config-subif)#interface serial 0/0/0.102 point-to-point
R1(config-subif)#ip address 192.168.1.245 255.255.255.252
R1(config-subif)#frame-relay interface-dlci 102 R1(config-subif)#end
