Trunking |
You manage a single subnet with three switches. The switches are connected to provide redundant paths between the switches. Which feature allows the switches to pass VLAN traffic between the switches? |
|
Trunking |
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 also in VLAN 1. What should you configure to allow communication between these two devices through the switches? |
|
Trunk ports |
When configuring VLANs on a switch, what type of switch ports are members of all VLANs defined on the switch? |
|
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 |
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 composition of the frame as it travels from A to B? |
|
Switches append a VLAN ID to the header of each frame to identify the virtual network to which it belongs. |
Which of the following statements accurately describes a VLAN ID? |
|
Increased security Increased number of broadcast domains |
Which of the following are reasons to configure VLANs on a switch as opposed to using switches without VLANs? (select two) |
|
You can create multiple broadcast domains |
Which of the following benefits apply only to creating VLANs with switches and not to segmenting the network with regular switches? |
|
2 |
You have two switches connected together as shown in the following diagram. How many broadcast domains are there in the network shown? |

Switch |
A virtual LAN can be created using which of the following? |
|
Switch |
You want to reduce collisions by creating separate collision domains and virtual LANs. Which of the following devices should you choose? |
|
Devices on the same network logically grouped as if they were on separate networks |
Which of the following best describes the concept of a VLAN? |
|
Switch port |
When configuring VLANs on a switch, what is used to identify VLAN membership of a device? |
|
Routing |
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 same switch which is in VLAN 2. What should you configure so that the two devices can communicate? |
|
VLANs |
You need to keep users in all other departments from accessing in the servers used by the finance department. Which of the following technologies should you use to logically isolate the network? |
|
Enter global configuration mode: conf t |
You need to configure the FastEthernet 0/1 interface on a switch to automatically detect the appropriate link speed and duplex setting by negotiating with the device connected to the other end of the link. Drag the command on the left to the appropriate configuration step on the right to accomplish this. Not all of the commands may be required. |
|
Enter global configuration mode: |
You need to disable the FastEthernet 0/0 interface on a switch. Drag the command on the left to the appropriate configuration step on the right to accomplish this. Not all of the commands may be required. |
|
Enter global configuration mode: |
The FastEthernet 0/0 interface on a switch is currently disabled. You need to enable it so a workstation can be connected to it. Drag the command on the left to the appropriate configuration step on the right to accomplish this. Not all of the commands may be required. |
|
Send it out all ports except for the port it was received on. |
A switch receives a frame addressed to the MAC address FF:FF:FF:FF:FF:FF. What will the switch do with the frame? |
|
ip default-gateway 192.168.10.185 |
Which command would you use on a switch to enable management from a remote network? |
|
configures the switch to obtain an IP address from a DHCP server |
What does the ip address dhcp command allow you to do? |
|
No, the no shutdown command needs to be entered |
You are configuring a switch so that you can manage it via PuTTY from the same network segment as the switch. On the switch, you enter the following commands: switch#config terminal switch(config)#interface vlan 1 switch(config-f)#ip address 192.168.1.10 255.255.255.0 |
