A switch receives a frame with a destination MAC address that is not found in its MAC address table. What happens next? A) The frame is replicated and sent to every active port on the switch except the source port. B) The frame is replicated and sent to every active port on the switch. C) The frame is rejected and returned to the source host. D) The frame stops at the switch and is not forwarded until the destination MAC address is manually added to the MAC address table.

A) The frame is replicated and sent to every active port on the switch except the source port.

You run a small network for your business that has a single router connected to the internet and a single switch. You keep sensitive documents on a computer that you would like to keep isolated from other computers on the network. Other hosts on the network should not be able to communicate with this computer through the switch, but you still need to access the network through the computer. Which of the following should you use in this situation? A) VLAN B) Port security C) VPN D) Spanning Tree

A) VLAN

Which of the following BEST describes Ethernet flow control? A) A configuration that allows frames larger than 1,500 bytes to pass through the port without fragmentation. B) A configuration that sends a pause frame to the transmitting device when the receiving device cannot keep up with the volume of data being sent. C) A protocol designed to prevent looping in network traffic. D) A configuration that allows traffic from multiple VLANs on a single port.

B) A configuration that sends a pause frame to the transmitting device when the receiving device cannot keep up with the volume of data being sent.

Which of the following BEST describes port aggregation? A) A priority-based flow control that allows you to prioritize network traffic. B) Multiple ports linked together and used as a single logical port. C) IEEE network standard 802.3. D) Multiple VLANs traveling through a single port.

B) Multiple ports linked together and used as a single logical port.

You are configuring a switch so that you can manage it using PuTTY from the same network segment. On the switch, you enter the following commands: switch#config terminalswitch(config)#interface vlan 1switch(config-if)#ip address 192.168.1.10 255.255.255.0 Will this configuration work? A) Yes. The switch can now be accessed by PuTTY using the IP address 192.168.1.10. B) No. The no shutdown command needs to be entered. C) No. The ip default-gateway command needs to be set. D) No. The switch needs to obtain an IP address from the DHCP server using the ip address dhcp command.

B) No. The no shutdown command needs to be entered.

You manage a network with two switches. The switches are connected together through their Gigabit Ethernet uplink ports. You define VLAN 1 and VLAN 2 on each switch. A device on the first switch in VLAN 1 needs to communicate with a device on the second switch in VLAN 1. What should you configure to allow communication between these two devices through the switches? A) Spanning Tree B) Trunking C) Layer 3 switching D) Bonding

B) Trunking

For which of the following devices does a voice VLAN prioritize traffic? A) Bridge B) VoIP phone C) Hub D) Layer 3 switch

B) VoIP phone

Which command would you use on a switch to enable management from a remote network? A) ip address 192.168.10.185 255.255.255.0 B) ip default-gateway 192.168.10.185 C) ip address dhcp D) no shutdown

B) ip default-gateway 192.168.10.185

Which of the following must each device's MTU be set to for jumbo frames to transverse the network without risk of fragmentation? A) 6,000 B) 3,000 C) 9,000 D) 1,500

C) 9,000

Computers A and B are on the same VLAN and are separated by two switches as shown in the exhibit. Computer A sends a frame to Computer B. Which of the following BEST describes the frame's composition as it travels from A to B? A) Computer A appends a VLAN ID to the frame. It travels from switch to switch and arrives at Computer B, where it removes the VLAN ID. B) Computer A sends a normal frame. The first switch forwards the frame to the second switch, where the VLAN ID is appended to the frame and forwarded to Computer B. C) Computer A sends a normal frame. The first switch appends a VLAN ID to the frame. The second switch removes the VLAN ID before forwarding it to Computer B. D) Computer A sends a normal frame. The first switch appends a VLAN ID to the frame. The VLAN ID remains on the frame through the second switch up to Computer B.

C) Computer A sends a normal frame. The first switch appends a VLAN ID to the frame. The second switch removes the VLAN ID before forwarding it to Computer B.
