What are two benefits of the IEEE 802.11n standard over the IEEE 802.11G? (Choose two.) requires less equipment provides improved range permits increased data rates has a single-input and a single-output needs no hardware upgrade for compatibility

Refer to the exhibit. Switch SW2 was tested in a lab environment and then inserted into a production network without reloading itsconfiguration. 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? All the VLANs were pruned from the trunk port between SW1 and SW2. SW1 and SW2 cannot be both set as VTP servers in the same VTP domain. VTP configuration revision number of SW2 was higher than the configuration revision number of SW1. The additionalVLANs from SW2 created more VLANs than the VLAN database of SW1 could contain. 3

Refer to the exhibit. Computer D sends a broadcast message. Which devices will process the broadcast message? computer E computer D and computer E computer D, computer E, and Router1 computer B and computer E computer B, computer E, and Router1 computer C, computer D, and computerE computer C, computer D, computer E, and Router1 computer A, computer B, computer C, computer D, computer E, and Router1 4

Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on switch SW1? Host A remains a member of VLAN 10, because the router is routing traffic between VLANs.

17/11/2009 19:22 Host A is no longer a member of VLAN 10, because port Fa0/3 has been manually assigned to VLAN 30. Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for the port. Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network. Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now amember of VLAN 1. 5

Refer to the exhibit. A new host needs to be connected to VLAN 1. Which IP address should be assigned to this new host? 192.168.1.11 /28 192.168.1.22 /28 192.168.1.33 /28 192.168.1.44 /28 192.168.1.55 /28 6

Refer to the exhibit. Both switches are interconnected via a trunk link. Host A and host B are on the default VLAN but are not able toexchange traffic. What should be done to fix the problem? Allow all VLANs on the trunk link. Remove the native VLAN from the trunk. Include a router or switch with Layer 3 capabilities. Configure the same native VLAN on both ends of the trunk. 7 Using the command copy tftp:backup.cfg startup-config, an administrator downloaded a saved configuration from a TFTP server to a switch. Why does theadministrator not detect any changes in the switch configuration after the download completes? The command should have been copy startup-config tftp:backup.cfg. A backup configuration from a TFTP server cannot be copied directly into the startup-config. The command copy running-config startup-config should be used to save the changes on the switch. Downloading to the startup-config requires theswitch to be reloaded in order for the configuration to take effect. 8

Refer to the exhibit. Hosts PC_A and PC_B send traffic simultaneously, and the frames from the transmitting stations collide. What is the last device to receive the collision? hub HB1 switch SW1 router R1 switch SW2 router R2 switch SW4 9 What are two benefits of a hierarchical network model overa flat network design? (Choose two.) reduced cost of equipment increased network availability elimination of equipment downtime reduced size of the physical network layout simplification of management and troubleshooting elimination of the need for Layer 3 functionality 10 What is an efficient and cost effective way to minimize the frequency and effects of broadcast storms on an Ethernet LAN?...
