Module 4 Pretest

What is the most compressed representation of the IPv6 address 2001:0000:0000:abcd:0000:0000:0000:0001?

2001:0:0:abcd::1

What subnet mask is represented by the slash notation /20?

255.255.240.0

How many bits are in an IPv4 address?'

32 bits

What are three characteristics of multicast transmission? (Choose three.)

A single packet can be sent to a group of hosts. Multicast transmission can be used by routers to exchange routing information. The range of 224.0.0.0 to 224.0.0.255 is reserved to reach multicast groups on a local network.

Refer to the exhibit. The network administrator for a small advertising company has chosen to use the 192.168.5.96/27 network for internal LAN addressing. As shown in the exhibit, a static IP address is assigned to the company web server. However, the web server cannot access the Internet. The administrator verifies that local workstations with IP addresses that are assigned by a DHCP server can access the Internet, and the web server is able to ping local workstations. Which component is incorrectly configured?

Default gateway address

Which range of link-local addresses can be assigned to an IPv6-enabled interface?​

FE80::/10

Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?

ICMPv6

Refer to the exhibit. Consider the IP address configuration shown from PC1. What is a description of the default gateway address?

It is the IP address of the Router1 interface that connects the PC1 LAN to Router1.*

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

SLACC

What are three parts of an IPv6 global unicast address? (Choose three.)

a global routing prefix that is used to identify the network portion of the address that has been provided by an ISP an interface ID that is used to identify the local host on the network a subnet ID that is used to identify networks inside of the local enterprise site

What field content is used by ICMPv6 to determine that a packet has expired?

hop limit field

What does the IP address 172.17.4.250/24 represent?

host address

What type of IPv6 address is FE80::1?

link local

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

link-local

What are two types of IPv6 unicast addresses? (Choose two.)

loopback link local

A technician uses the ping 127.0.0.1 command. What is the technician testing?

the TCP/IP stack on a network host*

Which two things can be determined by using the ping command? (Choose two.)

the average time it takes a packet to reach the destination and for the response to return to the source the destination device is reachable through the network

Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?

to identify the network address of the destination network*
