ICMP (Internet Control Message Protocol) is defined in RFC 792, and is used to manage and control the operation of a TCP/IP network. Which of the following would be the most accurate description of the error code: Protocol unreachable?

The ‘Protocol unreachable’ code indicates that the packet does not have a match in destination rout-ing table.

This code is used to identify that the packet was able to be routed to a router that is connected at the destination, but the host is not responding.

The ‘Protocol unreachable’ code indicates that the packet was able to be delivered but the destination port was not able to be opened by an application.

This code is used to identify that the packet was delivered but the Transport layer protocol was not available at the host.

None of the above.

Which of the following statements would be the most accurate in regards to the Cisco three-layer hierarchical model?

When designing the distribution layer it is important to keep high reliability and speed in mind as well as choosing fast routing protocols with low convergence times.

It is important to consider high speed and low latency when designing the core layer.

The distribution layer handles traffic for remote services and creates separate collision domains.

The core layer is responsible for technologies such as Ethernet switching, as well as static routing.

Cut through switching examines the destination address (first 8 bytes after the preamble) and then forwards the frame.

Cut through switching examines the destination address (first 16 bytes after the preamble) and then forwards the frame.

Fragment free switching examines the first 64 Bytes (Collision Window), runs a CRC check and then forwards the frame.

Fragment free switching examines the first 16 Bytes (Collision Window), runs a CRC check and then forwards the frame.
