Chapter 9-11

Consider the following range of addresses: 2001:0DB8:BC15:00A0:0000:: 2001:0DB8:BC15:00A1:0000:: 2001:0DB8:BC15:00A2:0000:: ... 2001:0DB8:BC15:00AF:0000:: The prefix-length for the range of addresses is

/60

Which two notations are useable nibble boundaries when subnetting in IPv6? (Choose two.)

/64* /68*

When subnetting a /64 IPv6 network prefix, which is the preferred new prefix length?

/72*

In dotted decimal notation, the IP address ________ is the last host address for the network 172.25.0.64/26.

172.25.0.126

In dotted decimal notation, the subnet mask ____ will accommodate 500 hosts per subnet.

255.255.254.0

Given the network address of 192.168.5.0 and a subnet mask of 255.255.255.224, how many addresses are wasted in total by subnetting each network with a subnet mask of 255.255.255.224? (CHP 9)

72*

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What issue is causing Host A to be unable to communicate with Host B?

Host A and host B are on overlapping subnets.*

Which two reasons generally make DHCP the preferred method of assigning IP addresses to hosts on large networks? (Choose two.)

It eliminates most address configuration errors.* It reduces the burden on network support staff.*

A host device is receiving live streaming video. How does the device account for video data that is lost during transmission?

The device will continue receiving the streaming video, but there may be a momentary disruption.*

What happens if part of an FTP message is not delivered to the destination? (CHP 9)

The part of the FTP message that was lost is re-sent.*

What does TCP do if the sending source detects network congestion on the path to the destination?

The source will decrease the amount of data that it sends before it must receive acknowledgements from the destination.*

What is a characteristic of a TCP server process?

There can be many ports open simultaneously on a server, one for each active server application.*

What kind of port must be requested from IANA in order to be used with a specific application?

What kind of port must be requested from IANA in order to be used with a specific application?

Why does HTTP use TCP as the transport layer protocol?

because HTTP requires reliable delivery*

When developing an IP addressing scheme for an enterprise network, which devices are recommended to be grouped into their own subnet or logical addressing group?

hosts accessible from the Internet*

When is UDP preferred to TCP?

when an application can tolerate some loss of data during transmission*
