A toner is used to trace a copper wire in a wall.

Which are the two main filters that firewalls use for data packets?

• IP addresses

• User accounts

• Applications

• Ports

Evaluate the underlined text in the following sentence. Select the correct answer if the underlined text does not make statement correct. Select "No change is needed" if the underlined text makes the statement correct.

A directly connected route has an administrative distance of 0.

• No change is needed

• 255

• 1

• 120

Answer explanation

A directly connected route has an administrative distance of 0.

A static route has a an administrative distance of 1.

RIP has an administrative distance of 120.

A route with an administrative distance of 255 is an unknown route.

Which of the following statements are true about RIP router protocols? (Choose two)

• A route cannot contain more than 15 hops.

• Route management becomes more effective as the network expands.

• Routes are calculated based on the number of hops required.

• Route changes are broadcast instantly through network.

Which two statements are true about Microsoft security zones? (Choose two)

• Internet Explorer has four security zones.

• Adding a website to a security zone blocks access to that website.

• The default security level for Local intranet and Trusted sites is the the same.

• The security level for Restricted sites can be changed.

• Windows Firewall is the application you must use to add or remove to security zones.

Answer explanation

Internet Explorer has four security zones: Internet, Local intranet, Trusted sites, or Restricted sites.

The default security level for Internet is Medium High.

The default security level for Local intranet and Trusted sites is the same, which is Medium.

The security levels for Internet, Local intranet, and Trusted can be changed.

The security level for Restricted sites is permanently set at High and cannot be changed.

What are two advantages of using mesh topology in a network? (Choose two)

• It is self-healing and can still operate when one node breaks down

• It is considered more reliable than other networks

• Data travels from node to node, with each node in the network handling each packet.

• The protocols used are very lightweight with little overhead.

Answer explanation

It is self-healing and can still operate when one node breaks down or a connection goes bad; therefore, it is considered more reliable than other networks.

Mesh topology has more protocols to handle things like collision detection and routing, which more overhead, but makes the network more reliable.

Packets in a mesh topology will not necessarily reach every node in the network.
