What are two features of ARP? (Choose two.)

If a device receiving an ARP request has the destination IPv4 address, it responds with an ARP reply,If a host is ready to send a packet to a local destination device and it has the IP address but not the MAC address of the destination, it generates an ARP broadcast.

What is done to an IP packet before it is transmitted over the physical medium?

It is encapsulated in a Layer 2 frame-When messages are sent on a network, the encapsulation process works from the top of the OSI or TCP/IP model to the bottom

Which two statements correctly describe a router memory type and its contents? (Choose two.)

RAM is volatile and stores the IP routing table.,ROM is nonvolatile and contains basic diagnostic software.

What PDU is associated with the transport layer?

Segment-The PDU for the transport layer is called a segment.

A technician with a PC is using multiple applications while connected to the Internet. How is the PC able to keep track of the data flow between multiple application sessions and have each application receive the correct packet flows?

The data flow is being tracked based on the source port number that is used by each application.

A network administrator enters the service password-encryption command into the configuration mode of a router. What does this command accomplish?

This command prevents someone from viewing the running configuration passwords.

What best describes the destination IPv4 address that is used by multicasting?

a single IP multicast address that is used by all destinations in a group
