A network administrator wants to have the same subnet mask for three subnetworks at a small site. The site has the following networks and numbers of devices: Subnetwork A: IP phones - 10 addresses Subnetwork B: PCs - 8 addresses Subnetwork C: Printers - 2 addresses What single subnet mask would be appropriate to use for the three subnetworks?

an increase in host-to-host ping response times

A network engineer is analyzing reports from a recently performed network baseline. Which situation would depict a possible latency issue?

link-local

At a minimum, which address is required on IPv6-enabled interfaces?

The physical address is added

During the encapsulation process, what occurs at the data link layer for a PC connected to an Ethernet network?

30

How many usable IP addresses are available on the 192.168.1.0/27 network?

drop the frame

If a device receives an Ethernet frame of 60 bytes, what will it do?

The frame has the broadcast address as the destination address. The destination address is unknown to the switch.

Under which two circumstances will a switch flood a frame out of every port except the port that the frame was received on?

port numbering use of checksum

What are two characteristics shared by TCP and UDP?

It completes the remainder of a partially typed word in a command.

What function does pressing the Tab key have when entering a command in IOS?

Which procedure is used to reduce the effect of crosstalk in copper cables?

SLAAC

Which service provides dynamic global IPv6 addressing to end devices without using a server that keeps a record of available IPv6 addresses?

Segments are sent from the transport layer to the internet layer

Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

fast-forward

Which switching method has the lowest level of latency?

route print netstat -r

Which two commands can be used on a Windows host to display the routing table?

packet forwarding path selection

Which two functions are primary functions of a router?

to enable a receiving host to forward the data to the appropriate application.
