Question 1

The subnet mask for a Class B IP address is ____.&#10;A)255.0.0.0&#10;B)255.255.0.0&#10;C)255.255.255.0&#10;D)255.255.255.255

Accepted Answer

A Class B IP address has a first octet in the range of 128-191, indicating that the network portion of the address is comprised of two octets. The subnet mask for this class of address is 255.255.0.0, which represents the first two octets as the network portion and the remaining two octets as the host portion.

Question 2

One method of setting up trusted access is to add the host names of computers to the ____ file on the remote computer.&#10;A)/etc/hosts.trusted&#10;B)/etc/hosts.tr&#10;C)/etc/hosts.eq&#10;D)/etc/hosts.equiv

Accepted Answer

The /etc/hosts.equiv file is used to configure trusted access in a UNIX-based system. It lists the host names of computers that are trusted for remote connections. Adding a host name to this file means that any user on that computer can access the remote computer without being prompted for a password. It is important to note that setting up trusted access using /etc/hosts.equiv can pose security risks and should be done with caution.

Question 3

The ____ ftp utility command uploads the filename from the current directory on the local computer to the current directory on the remote computer, and allows the use of wildcard metacharacters to specify the filename .

A)upload filename
B)mput filename
C)put filename
D)get filename

B

Accepted Answer

The "mput" command is used to upload multiple files at once from the local computer to the remote computer, and it allows the use of wildcard metacharacters to specify the filenames. The "upload" and "put" commands refer to the same action of uploading a single file, but do not have the wildcard functionality. The "get" command is used to download a file from the remote computer to the local computer.

Question 4

Class D addresses are used for multicasting.

Accepted Answer

Class D addresses are designated for multicasting, while Class A, B, and C addresses are used for unicast and anycast.

Question 5

The use of NFS is less common than the use of FTP to transfer files among UNIX and Linux computers.

Accepted Answer

NFS is a more common file sharing protocol than FTP for UNIX and Linux computers.

Question 6

The subnet mask for a Class C IP address is ____.&#10;A)255.0.0.0&#10;B)255.255.0.0&#10;C)255.255.255.0&#10;D)255.255.255.255

Accepted Answer

For a Class C IP address, the first three octets represent the network portion of the address and the last octet represents the host portion. The subnet mask needs to identify the network portion, which is 24 bits for Class C addresses. 255.255.255.0 is a 24-bit subnet mask that identifies the network portion of a Class C address.

Question 7

The ____ command sends a small TCP/IP packet to another IP address and awaits a response.&#10;A)ping&#10;B)ring&#10;C)png&#10;D)ipquery

Accepted Answer

The ping command is used to test the connectivity between two devices by sending a small packet and waiting for a response. It is commonly used as a troubleshooting tool to determine if a network device is responding properly.

Question 8
