Question No. 1

The COMSTAR framework provides support for the iSCSI protocol.

Select three options that correctly describe the COMSTAR framework.

AiSCSI devices can be used as dump devices.

BSCSI commands are carried over IP networks and enable you to mount disk devices from across the network onto your local system.

CLarge amounts of data can be transferred over an IP network with very little network degradation.

DCOMSTAR allows you to convert any Solaris11 host into a SCSI target device that can be accessed over a storage network.

EOne IP port can handle multiple ISCSI target devices.

Show Answer

Correct Answer: B, D, E

B: By carrying SCSI commands over IP networks, the iSCSI protocol enables you to access block devices from across the network as if they were connected to the local system. COMSTAR provides an easier way to manage these iSCSI target devices.

D: Common Multiprotocol SCSI TARget, or COMSTAR, a software framework that enables you to convert any Oracle Solaris 11 host into a SCSI target device that can be accessed over a storage network by initiator hosts.

E: One IP port can handle multiple iSCSI target devices.

Question No. 2

Which files must be edited in order to set up logging of all failed login attempts?

A/etc/default/login, /var/adm/loginlog, /etc/syslog.conf

B/etc/default/login, /var/adm/authlog, /etc/syslog.conf

C/var/adm/loginlog, /var/adm/authlog, /etc/syslog.conf

D/etc/default/login, /var/adm/authlog, /var/adm/loginlog

Show Answer

Correct Answer: B

This procedure captures in a syslog file all failed login attempts.

1. Set up the /etc/default/login file with the desired values for SYSLOG and SYSLOG_FAILED_LOGINS

Edit the /etc/default/login file to change the entry. Make sure that SYSLOG=YES is uncommented.

2. Create a file with the correct permissions to hold the logging information.

Create the authlog file in the /var/adm directory.

3. Edit the syslog.conf file to log failed password attempts.

Send the failures to the authlog file.

Question No. 3

You are creating a non-global zone on your system.

Which option assigns a zpool to a non-global zone, and gives the zone administrator permission to create zfs file system in that zpool?

AWhile creating the non-global zone, make the following entry: add deviceset match=/dev/rdsk/c4t0d0endBoot the zone and log in the zone as root. Create the zpool: zpool create pool2 c4t0d0In the non-global zone, root can now create ZFS file system in the pool2 zpool

BIn the global zone, create the zpool: global# zpool create pool2 c4t1d0While creating the no-global zone, make the following entry: add datasetset name=pool2endadd fsset dir=pool1set special=pool1set type=zfspool1endBoot the zone, log in the zone as root, and create the zfs file system in the pool2 zpool.

CIn the global zone, create the zpool:global#zpool create pool2 c4t1d0While creating the global zone, make the following entry: add datasetset name=pool2endBoot the zone, log in to the zone as root and create the zfs file systems in the pool2 zpool.

DIn the global zone, create the zpool and the ZFS file systems that you want to use in the non-global zone: global#zpool create pool2 c4t1d0global#zfs create pool2/dataWhile creating the non-global zone, make the following entry for each ZFS file system that you want to make available in the zone: add fsset dir=/dataset special=pool2/dataset type=zfsend

ECreate the zpool in the global zone: global#zpool create pool2 c4t1d0Boot the non-global zone, log in to the zone as root, and issue this command to delegate ZFS permissions to root: non-global zone# zfs allow root create , destroy, mount pool2Log in to the non-global zone create ZFS file systems in the pool2 zpool.

Question No. 4

When you issue the ''gzip: zommand not found'' message is displayed. You need to install the gzip utility on your system.

Which command would you use to check if the gzip utility is available from the default publisher for installation?

Apkg info|grep gzip

Bpkg list SUNWgzip

Cpkg contents gzip

Dpkg search gzip

Show Answer

Correct Answer: D

Searching for Packages

Use the pkg search command to search for packages whose data matches the specified pattern.

Like thepkg contentscommand, thepkg searchcommand examines the contents of packages. While thepkg contentscommand returns the contents, thepkg searchcommand returns the names of packages that match the query.

pkg search

search [-HIaflpr] [-o attribute ...] [-s repo_uri] query

Search for matches to the query, and display the results.

Which tokens are indexed are action-dependent, but may include content hashes and pathnames.

Note: pkg is the retrieval client for the image packaging system. With a valid configuration, pkg can be invoked to create locations for packages to be installed, called 'images', and install packages into those images. Packages are published by publishers, who may make their packages available at one or more repositories. pkg, then, retrieves packages from a publisher's repository and installs them into an image.

Question No. 5

A user account must be a member of a primary group, and may also be a member of one or more secondary groups. What is the maximum total number of groups that one user can concurrently belong to?

A15

B16

C17

D63

E64

F65

GThe number of groups one user can concurrently belong to is unlimited in Solaris 11.

Show Answer

Correct Answer: B

Each user belongs to a group that is referred to as the user's primary group. The GID number, located in the user's account entry within the /etc/passwd file, specifies the user's primary group.

Each user can also belong to up to 15 additional groups, known as secondary groups. In the /etc/group file, you can add users to group entries, thus establishing the user's secondary group affiliations.

Note (4 PSARC/2009/542):

his project proposes changing the maximum value for NGROUPS_MAX from 32 to 1024 by changing the definition of NGROUPS_UMAX from 32 to 1024.

The use for a larger number of groups is described in CR 4088757, particular in the case of Samba servers and ADS clients; the Samba servers map every SID to a Unix group. Users with more than 32 groups SIDs are common. We've seen reports varying from '64 is enough', '128 is absolutely enough' and 'we've users with more 190 group SIDS).

NGROUPS_MAX as defined by different Unix versions are as follows (http://www.j3e.de/ngroups.html):

Linux Kernel >= 2.6.3 65536

Linux Kernel < 2.6.3 32

Tru64 / OSF/1 32

IBM AIX 5.2 64

IBM AIX 5.3 ... 6.1 128

OpenBSD, NetBSD, FreeBSD, Darwin (Mac OS X) 16

Sun Solaris 7, 8, 9, 10 16 (can vary from 0-32)

HP-UX 20

IRIX 16 (can vary from 0-32)

Plan 9 from Bell Labs 32

Minix 3 0 (Minix-vmd: 16)

QNX 6.4 8
