What is the basic purpose of a local area network (LAN)?

• To interconnect networks in several different buildings
• To connect one or more computers together so they can share resources
• To connect one or more computers together so they can share resources
• To make routers unnecessary

You need a topology that is easy to troubleshoot and scalable. Which would you use

• Star
• Bus
• Mesh
• Ring

IP resides at which layer of the OSI model

• Application
• Datalink
• Network
• Physical

Layer 2 of the OSI model is named

• Application
• Network
• Physical
• Datalink

If you wanted to verify the local IP stack on your computer, what would you do

• ping 128.0.0.0
• ping 127.0.0.1
• ping 1.0.0.127
• ping 169.254.1.1

What is the subnetwork address for a host with the IP address 200.10.5.168/28

• 200.10.5.156
• 200.10.5.132
• 200.10.5.160
• 200.10.5.0

You need to break up broadcast domains in a Layer 2 switched network. What strategy will you use?

• Implement a loop-avoidance scheme
• Create a flatter network structure using switches
• Create a VLAN
• Disable spanning tree on individual ports

Why do most switches run the Spanning Tree Protocol by default

• It monitors how the network is functioning
• It stops data from forwarding until all devices are updated.
• It prevents switching loops
• It manages the VLAN database

Which of the following describes MIMO correctly

• A protocol that requires acknowledgment of each and every frame
• A data-transmission technique in which several frames are sent by several antennae over several paths and are then recombined by another set of antennae
• A modulation technique that allows more than one data rate
• A technique that packs smaller packets into a single unit, which improves throughput

IPSec is defined at what layer of the OSI model

• Network
• Physical
• Layer 4
• Layer 7
