Question No.23

You are troubleshooting the failure of a computer to mount an NFS file system hosted by a server (hostname mars) in the local area network. Select the three commands that will enable you to identify the problem.

  1. ping – s mars

  2. cat /etc/vfstab

  3. cat /etc/dfs/dfstab

  4. sharemgr show -v

  5. showmount -e mars

  6. rpcinfo -s mars | egrep `nfs|mountd#39;

Correct Answer: AEF

Explanation:

mount: mount-point /DS9 does not exist.

To solve the mount point error condition, check that the mount point exists on the client. Check the spelling of the mount point on the command line or in the /etc/vfstab file (B) on the client, or comment outthe entry and reboot the system.

Note:

The /etc/vfstab file lists all the file systems to be automatically mounted at system boot time, with the exception of the /etc/mnttab and /var/run file systems.

E: showmount

This command displays all clients that have remotely mounted file systems that are shared from an NFS server, or only the file systems that are mounted by clients, or the shared file systems with the client access information. The command syntax is:

showmount [ -ade ] [ hostname ]

where -a prints a list of all the remote mounts (each entry includes the client name and the directory), -d prints a list of the directories that are remotely mounted by clients, -e prints a list of the files shared (or exported), and hostname selects the NFS server to gather the information from. If hostname is not specified the local host is queried.

F: * mountd Daemon

This daemon handles file-system mount requests from remote systems and provides access control. The mountd daemon checks /etc/dfs/sharetab to determine which file systems are available for remote mounting and which systems are allowed to do the remote mounting.

Commands for Troubleshooting NFS Problems

These commands can be useful when troubleshooting NFS problems. rpcinfo Command

This command generates information about the RPC service that is running on a system. Reference: man showmount

Question No.24

You need a copy of the zone configuration installed on your server for disaster recovery documentation. Which two commands would display the current configuration of the zone named testzone? (Choose two)

  1. zonecfg -z testzone i nfo

  2. zoneinfo -z testzone

  3. zoneadm -z testzone info

  4. zonecfg -z testzone export

  5. zonecfg testzone info

  6. cat /etc/zones/testzone.cfg

Correct Answer: DE

Question No.25

Select the two correct descriptions of the configuration of a default installation of Oracle Solaris

  1. (Choose two.)

    1. The root account no longer exists.

    2. Access to the root account is restricted by RBAC.

    3. The Solaris Management Console GUI (SMC) can be used to assign the root role to a user.

    4. telnet, ftp, and other services are disabled for network access, but root can log in by using SSH.

    5. Any logged in user, who knows the password for the root account, can modify the system configuration.

    6. usermod -R root alice will allow user alice to assume the role of root to modify the system configuration.

Correct Answer: BE

Question No.26

You run the command dlstat show-link -r. Select the two correct statements regarding the information displayed in the INTRS column.

  1. No value is listed for virtual network interfaces.

  2. A value of 0 is listed for virtual interfaces and ether stubs.

  3. The number of Interrupts is listed, which indicates network efficiency.

  4. A number equal to the number of transmitted Ethernet frames is listed for physical links.

  5. The number of packets that were interrupted by a collision is listed, which may indicate hardware problems.

Correct Answer: CE

Explanation:

In this output, the statistics for interrupt (INTRS) are significant. Low interrupt numbers indicate greater efficiency in performance. If the interrupt numbers are high, then you might need to add more resources to the specific link.

Example:

# dlstat -r -i 1

LINK IPKTS RBYTES INTRS POLLS CHlt;10 CH10-50 CHgt;50 e1000g0 101.91K 32.86M 87.56K 14.35K 3.70K 205 5

Note:

dlstat show-link [-r [-F] | -t] [-i interval] [-a] [-p] [ -o field[,…]] [-u R|K|M|G|T|P] [link]

Display statistics for a link. r

Display receive-side statistics only. Includes bytes and packets received, hardware and software drops, and so forth.

List of supported RX fields: link

iusedby ibytes ipkts intrs polls

hdrops: hardware drops

sdrops: software drops (owing to bandwidth enforcement) chlt;10: number of packet chains of length lt; 10

ch10-50: number of packet chains of length between 10 and 50 chgt;50: number of packet chains of length gt; 50

Reference: man dlstat

Question No.27

You want to configure an iSCSI target device on your system. Select the group package required to install this functionality on your system.

  1. storage-server

  2. solaris-small-server

  3. storage-avs

  4. storage-nas

Correct Answer: A

Explanation:

How to Create an iSCSI LUN

The disk volume provided by the server is referred to as the target. When the LUN is associated with an iSCSI target, it can be accessed by an iSCSI initiator. The following tasks are completed on the system that is providing the storage device.

1. Install the COMSTAR storage server software. target# pkg install storage-server

Etc.

Question No.28

Which command should you choose to display the current parameters for the FSS scheduler?

  1. dispadmin – c FSS

  2. prionctl -c FSS

  3. dispadmin -c FSS -g

  4. priocntl -c FSS -g

Correct Answer: C

Explanation:

The dispadmin command displays or changes process scheduler parameters while the system is running.

c class

Specifies the class whose parameters are to be displayed or changed.

Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter- active class, FSS for the fair-share class, and FX for the fixed-priority class. The time-sharing and inter- active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.

g

Gets the parameters for the specified class and writes them to the standard output. Reference: man dispadmin

Question No.29

The following information is displayed during the migration of a ZFS file system:

image

  2. The shadowed file system is named pool1/data1, the shadowstat command was used to generate the output, and the migration is still in progress

  3. 25.5 GB of data has been transferred so far. 409 MB of data remains to be transferred

  4. The shadowed file system is named pool1/data1. the shadowstat command was used to generate the output, and the migration is still in progress with 409 MB remaining to be transferred to the target filesystem.

  5. The new file system is named pool1/data1, the shadow command was used to generate the output, and the migration is still in progress.

  6. The shadowed file system is named pool1/data1, the shadow command was used to generate the output, and the migration is still in progress.

  7. 27.3 GB is the exact size of the data that is yet to be transferred from the shadowed file system.

Correct Answer: F
