You wish to enable the interface on the Cisco router; what command would you use?
Shutdown
Enable
No shutdown
No shutdown
The no shutdown command is used to enable an interface on a Cisco device
Which of the following commands would you use to assign an IP address to an interface?
Router(config-if)#ip address 10.0.0.1 255.0.0.0
Router(config)#ip address 10.0.0.1 255.0.0.0
Router#ip address 10.0.0.1 255.0.0.0
Router(config-if)#ip address 10.0.0.1 255.0.0.0
To assign an IP address to an interface, you use the IP address command at an interface prompt
You want to ensure that the network interface on the router is using full duplex. What command would you use?
Router(config)#duplex full
Router(config-if)#duplex half
Router(config-if)#duplex full
Router(config-if)#duplex full
To configure the interface for full-duplex mode, you use the duplex full command at
Your manager is concerned about unauthorized systems being able to connect to the network. What feature of a switch can settle her concerns?
STP
Port security
Port mirroring
Port security
The port security feature allows you to specify the MAC addresses of systems that can connect to each port
Which of the following protocols is responsible for preventing loops on the network?
TCP
VTP
STP
STP
The Spanning Tree Protocol (STP) is designed to prevent loops on the network
Which of the following protocols are responsible for VLAN tagging? (Choose two.)
802.1Q
TCP
ISL
STP
802.1Q
ISL
802.1Q is the IEEE standard for VLAN tagging, while ISL is a Cisco protocol for VLAN tagging
ou have a number of IP phones that you wish to connect to the switch in order for the phone to be powered by the switch using PoE. Which of the following standards would you look for that is supported by the switch?
- 1Q
- 3af
Port mirroring
- 3af
- 3af is the IEEE standard for Power over Ethernet (PoE), which is a feature that allows the switch to supply power to devices through the Ethernet connection. This is a common feature used by IP phones so that the phone does not need a separate power source
You are troubleshooting a system that cannot communicate with SERVER1 when connected to ports 1 through 6, but can when you connect the system to ports 8 through 12. What may be the reason?
Ports 1 through 6 may be using the wrong subnet mask.
Ports 1 through 6 may have the wrong IP address.
Ports 1 through 6 may be in a different VLAN than SERVER1.
Ports 1 through 6 may be in a different VLAN than SERVER1.
If you are having trouble communicating with systems when connecting to a specific port on the switch, it could be because the port is part of a specific VLAN. Remember that you can only communicate with systems in the same VLAN
You are a router administrator, and clients on your network are having trouble communicating with a system that has the IP address of 122.34.5.4. You have verified that the IP configuration of your clients, including the default gateway setting, is correct. You can communicate with systems on your network and other networks. What should you check?
Verify the routes in the routing table.
Change the subnet mask.
Change the IP address to match the IP address of the system you are connecting to.
Verify the routes in the routing table.
If you are having trouble communicating with a specific network, you should verify that there is a route to that network in the routing table on the router
Your company policy is to have all network traffic sent to port 24 on the switch so that the administrator can have monitoring software check all network activity. What is the name of this switch feature?
Security monitoring
Packet sniffer
Port mirroring
Port mirroring
Port mirroring is the feature on the switch that allows you to send a copy of all traffic to a specified port and monitor the traffic from that port
