Refer to the exhibit. Switch SW2 has been newly purchased and added to the network. What configuration should be applied to SW2 so that it participates in the same VTP domain as switch SW1, receives VLAN information from SW1, and synchronizes VLAN information? A. Disable VTP pruning on SW2. B. Configure SW2 in VTP transparent mode. C. Configure SW2 with the VTP domain password. D. Configure SW2 as a VTP server with a higher revision number. 3

Refer to the exhibit. Switch SW2 was tested in a lab environment and then inserted into a production network without reloading its configuration. After the trunk link between SW1 and SW2 was brought up, all users lost connectivity to the network. What could be the source of the problem? A. All the VLANs were pruned from the trunk port between SW1 and SW2. B. SW1 and SW2 cannot be both set as VTP servers in the same VTP domain. C. VTP configuration revision number of SW2 was higher than the configuration revision number of SW1. D. The additional VLANs from SW2 created more VLANs than the VLAN database of SW1 could contain. 4 Which three actions are performed during the boot sequence of a Cisco switch? (Choose three.) A. The boot loader uses the self-contained switch operating system to boot the switch. B. The boot loader retrieves diagnostics routines via TFTP. C. The boot loader performs POST. D. The boot loader is loaded from RAM. E. The boot loader initializes the flash file system that is used to boot the system. F. The boot loader loads the default operating system if the flash-based operating system is corrupt or missing. 5 Which two conditions would require a VTP client to send a request advertisement to a VTP server? (Choose two.) A. The switch has been reset. B. A VLAN has been created or deleted. C. A five minute time period has elapsed. D. The name of a VLAN has been changed. E. The VTP domain name has been changed. 6 Which method establishes an administrative connection for configuring the Linksys WRT300N wireless access point? A. Associate with the access point and then open a HyperTerminal session with the access point. B. Physically connect to the access point and then reboot the computer to launch the configuration software. C. From a computer in the same IP subnet as the access point, enter the default IP address of the access point in a web browser. D. Modify the TCP/IP properties of the computer connected to the access point so that it exists on the same network, and then reboot your computer to establish a connection. 7

Refer to the exhibit. What is the maximum number of VLANs that can be deleted from the Switch as it is configured? A. zero B. four C. five D. eight E. nine 8 Refer to the exhibit. Switches S2 and S3 are properly connected using an ethernet cable. A network administrator has configured both switches with VTP, but S3 is unable to propagate VLANs to S2. What could be the reason for this? A. The VTP configuration revision is different on both switches. B. The VTP domains are different on both switches. C. VTP pruning is disabled. D. VTP v2 is disabled. 9 Refer to the exhibit. Hosts that are connected to switch SW1 are not able to communicate with hosts in the same VLAN that are connected to switch SW2. What should be done to fix the problem? A. Introduce a Layer 3 device in the topology. B. Configure both switches in VTP transparent mode to allow them to share VLAN information. C. Reconfigure the fa0/1 interface on switch SW1 with a static trunk configuration. D. Apply IP addresses that are in the same subnet to FastEthernet 0/1 on SW1 and FastEthernet 0/2 on SW2. 10 What is a result of improperly implementing a network with redundancy at Layer 2? A. an increase of unicast and multicast errors at Layer 3 B. a decrease in the amount of broadcast traffic C. end device malfunction because of broadcast storms D. an increase in throughput at all points in the network 11 Company policy requires disabling the command history buffer on network devices. An administrator enters terminal no history size at the command prompt on a Cisco Catalyst switch and receives no error messages back, but the command history buffer is still available. What is the problem? A. The command contained a syntax error. B. The Cisco IOS version does not support disabling the command history buffer. C. The command history can only be disabled on a router, not a switch. D. The size parameter reset the default buffer size but did not disable access to the buffer. 12
