You need to know the IP address configured on interface net3, and that the interface is up. Which command confirms these?

1. A. ipadm show-if
2. B. ipadm up-addr
3. C. ipadm show-addr
4. D. ipadm enable-if
5. E. ipadm refresh-addr
6. F. ipadm show-addrprop

Correct Answer: C
Show address information, either for the given addrobj or all the address objects configured on the specified interface, including the address objects that are only in the persistent configuration.
State can be: disabled, down, duplicate, inaccessible, ok, tentative Example:
# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8 lo0/v6 static ok ::1/128

You are the administrator for a group of shell script developers. They use vi, and have asked you to make their scripts automatically executable when they save their files.
How can this be accomplished?

1. A. Enter set –o vi on the command line, or include it in each user's startup script.
2. B. Enter umask –s on the command line, or include it in each user's startup script.
3. C. Enter umask 000 on the command line, or include it in each user's startup script.
4. D. Enter umask 777 on the command line, or include it in each user's startup script.
5. E. It is not possible to automatically set the execute bit on with the umask setting, or vi option.
6. F. Enter umask 766 the command line, or include it in the global startup script for the default shell.

Correct Answer: E
Unlike DOS, which uses the file extension to determine if a file is executable or not, UNIX relies on file permissions.
The value assigned by umask is subtracted from the default.
User's file creation mask. umask sets an environment variable which automatically sets file permissions on newly created files. i.e. it will set the shell process's file creation mask to mode.
umask 000 would grant full permissions. Note: 777 full permissions

Oracle Solaris 11 limits access to the system with usernames and passwords.
The usernames are held in , and the passwords are held in . Select the correct pair.

1. A. /etc/security/policy.conf /etc/passwd
2. B. /etc/passwd /etc/shadow
3. C. /etc/security /etc/passwd
4. D. /etc/shadow /etc/passwd

Correct Answer: B
The /etc/passwd file contains basic user attributes. This is an ASCII file that contains an entry for each user. Each entry defines the basic attributes applied to a user.
/etc/shadow file stores actual password in encrypted format for user's account with additional properties related to user password i.e. it stores secure user account information. All fields are separated by a colon (:) symbol. It contains one entry per line for each user listed in /etc/passwd file.

Select the packet type that identifies members of the group and sends information to all the network interfaces in that group.

1. A. Unicast
2. B. Multicast
3. C. Broadcast
4. D. Bayesian
5. E. Quality of Service Priority

Correct Answer: B
IPv6 defines three address types: unicast
Identifies an interface of an individual node.
multicast
Identifies a group of interfaces, usually on different nodes. Packets that are sent to the multicast address go to all members of the multicast group.
anycast
Identifies a group of interfaces, usually on different nodes. Packets that are sent to the anycast address go to the anycast group member node that is physically closest to the sender.
