Networking - Chapter 8

Which statement accurately describes public IP addresses?

Public IP addresses must be unique across the entire Internet.

The 8-bit binary value for 41 is

00101001 32 + 8 + 1 = 41

The last host address on the 10.15.25.0/24 network is

Your organization is issued the IPv6 prefix of 2001:0000:130F::/48 by your service provider. With this prefix, how many bits are available for your organization to create subnetworks?

16

Match the legacy IP address class with the answer that represents the entire private address range reserved within that class. (Not all options are used.)

A = 10.0.0.0 - 10.255.255.255 B = 172.16.0.0 - 172.31.255.255 C = 192.168.0.0 - 192.168.255.255

Which statement is true about an interface that is configured with the IPv6 address command?

A link-local IPv6 address is automatically configured on the interface.

Which two statements describe broadcast transmissions on a wired network? (Choose two.)

Directed broadcasts are intended for all hosts on a local or remote network. Limited broadcasts are only intended for the hosts on a local network.

Fill in the blank. The shortest compressed format of the IPv6 address 2001:0DB8:0000:1470:0000:0000:0000:0200 is________

2001:DB8:0:1470::200

A network administrator notices that the default gateway device sends an ICMP Redirect message to the workstation when the workstation tries to connect to a file server on another network. What is the purpose for this ICMP message?

To notify the workstation, that another router on the same network, is the better default-gateway to reach the remote server.

A user is unable to access the company server from a computer. On issuing the ipconfig command, the user finds that the IP address of the computer is displayed as 169.254.0.2. What type of address is this?

link-local Refer to curriculum topic: 8.1.4 IPv4 addresses in the address block 169.254.0.0 to 169.254.255.255 are link-local addresses. The operating system of a host can automatically assign an address from this block to the host in case no IP configuration is available. An example is when a host is configured to obtain a dynamic IP address but cannot reach any DHCP server during the boot process. In such a case, the operating system can assign a link-local address.

Which type of IPv6 address is not routable and used only for communication on a single subnet?

link-local address

A user who is unable to connect to the file server contacts the help desk. The helpdesk technician asks the user to ping the IP address of the default gateway that is configured on the workstation. What is the purpose for this ping command?

to test if the workstation can communicate on the network
