1Z0-821 Exam Questions Get Updated [2024] with Correct Answers

Oracle 1Z0-821 exam consists of 150 multiple-choice questions that must be completed within 150 minutes. 1Z0-821 exam covers various topics, including installation, network configuration, security, storage management, virtualization, and troubleshooting. Candidates must have a solid understanding of these topics to pass the exam.

NO.143 user1,while in his home directory,is attempting to run the following command in his home directory: cp bigfile verybig
The system displays the following error:
cp: cannot create verybig: Disc quota exceeded
Your initial troubleshooting shows that the df -h command indicates he is at 100% capacity. What command would you use to increase the disk space available to the user?

zfs get quota rpool/export/home/user1

zfs userused@user1

zfs quota=none /rpool/export/home/user1

df -h | grep user1

zfs set quota=none /rpool/export/home/user1

ZFS quotas can be set and displayed by using the zfs set and zfs get commands. We can remove the quota restriction by setting to quota to none.

NO.144 You are setting up a local IPS package repository on your Oracle Solaris11 server: solaris.example.com.
You want to point the existing local IPS publisher to the new local IPS repository located in /repo.
These are the stops that you have followed:
1. Download and rsync the contents of the Oracle Solaris11 repository ISO image to the /repo directory.
2. Configure the repository server service properties. The svcprop command display, the IPS related properties:
pkg/inst_root astring/repo
pkg/readonly Boolean true
The 1s command displays the contents of the /repo directory:
#ls/repo
Pkg5.repository publisher
The svcs publisher command shows the svc: /application/pkg/server: default service is online.
The pkg publisher command shows the svc: /application/pkg/server: default service is online.
The pkg publisher command still displays:
PUBLISHERTYPESTATUSURI
solarisoriginonlinehttp://pkg.oracle.com/solaris/release/
Which steps needs to be performed to set the local IPS publisher to the local IPS repository/repo?

Issue the pkgrepo refresh -s command to refresh the repository.

Restart the svc:/application/pkg/server:default service.

pkg set-publisher command to set the new repository location.

Issue the pkgrepo rebuild command to rebuild the repository.

Issue the pkgrepo set command to set the new repository location.

Explanation/Reference:
Explanation:
Set the Publisher Origin To the File Repository URI
To enable client systems to get packages from your local file repository, you need to reset the origin for the solaris publisher. Execute the following command on each client:
Example:
# pkg set-publisher -G ‘*’ -M ‘*’ -g /net/host1/export/repoSolaris11/ solaris

NO.145 Consider the following commands:

What is displayed when this sequence of commands is executed using the bash shell?

Hello, world

cat: cannot open file1

cat: cannot open file1Hello, world

cat: cannot open file1 Hello, World

bash: syntax error near unexpected token ‘&&’

First line (rm file1) deletes/removes file1.
Second line captures the text into file2.
The first part of line 3 (cat file1) fails as the file1 does not exist.
The && (AND) operator will ensure that the third line fails. The result of line 3 will be the result of first part of line 3 (cat file1).
Note: cat – concatenate files and print on the standard output
Note #1: A list is a sequence of one or more pipelines separated by one of the operators ‘;’,
‘&’, ‘&&’, or ‘||’, and optionally terminated by one of ‘;’, ‘&’, or a newline.
Of these list operators, ‘&&’ and ‘||’ have equal precedence, followed by ‘;’ and ‘&’, which have equal precedence.
AND and OR lists are sequences of one or more pipelines separated by the control operators ‘&&’ and ‘||’, respectively. AND and OR lists are executed with left associativity.
An AND list has the form
command1 && command2
command2 is executed if, and only if, command1 returns an exit status of zero.
An OR list has the form
command1 || command2
command2 is executed if, and only if, command1 returns a non-zero exit status.
The return status of AND and OR lists is the exit status of the last command executed in the list.
Note #2 (on exit status): Zero means command executed successfully, if exit status returns non-zero value then your command failed to execute.

NO.146 You need to install the gzip software package on your system. Which command would you use to find the software package in the configured repository?

pkg search gzip

pkg info gzip

pkg contents gzip

pkginfo gzip

yum list gzip

Explanation/Reference:
Explanation:
Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.

NO.147 You have set up the task.max-lwps resource control on your Solaris 11 system.
Which option describes how to configure the system so that syslogd notifies you when the resources control threshold value for the task.max-lwps resource has been exceeded?

Use the rctladm command to enable the global action on the task.max-lwpa resource control.

Modify the /etc/syslog.conf file to activate system logging of all violations of task.maxlwps and then refresh then svc: /system/system-log:default service.

Activate system logging of all violations of task.max-lwpp in the /etc/rctldm.conf file and then execute the rctladm-u command.

Use the prct1 command to set the logging of all resource control violations at the time the task.max-lwps resource control is being setup.

Use the setrct1 command to set the logging of all resource control violations for the task.max-lwps resource control.

rctladm – display and/or modify global state of system resource controls
The following command activates system logging of all viola-tions of task.max-lwps.
# rctladm -e syslog task.max-lwps #

NO.148 You have been asked to do an orderly shutdown on a process with a PID of 1234, with the kill command.
Which command is best?

kill -2 1234

kill -15 1234

kill -9 1234

kill -1 1234

Explanation/Reference:
Explanation:
On POSIX-compliant platforms, SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be caught and interpreted (or ignored) by the process.
Therefore, SIGTERM is akin to asking a process to terminate nicely, allowing cleanup and closure of files.
For this reason, on many Unix systems during shutdown, init issues SIGTERM to all processes that are not essential to powering off, waits a few seconds, and then issues SIGKILL to forcibly terminate any such processes that remain.

NO.149 View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system.

Which two options describe the solaris-1 boot environment?

The solaris-1 boot environment is not bootable.

The solaris-1 boot environment is incomplete.

The solaris-1 boot environment was created automatically when the non global zone was created.

The solaris-1 boot environment was created in the non-global zone using the beadm create command.

The solaris-1 boot environment is associated with a non active global zone boot environment.

A: The – of the Active Column indicates that this boot environment is inactive,and hence not bootable.
Note: The values for the Active column are as follows: R – Active on reboot.
N – Active now.
NR – Active now and active on reboot.
“-” – Inactive.
“!” – Unbootable boot environments in a non-global zone are represented by an exclamation point.
D: beadm create
Creates a new boot environment name,beName.
Note: beadm list
Lists information about the existing boot environment,which is be Name,or lists information
for all boot environments if be Name is not provided.
Note: Using beadm Utility (Tasks)
You can use the beadm utility to create and manage snapshots and clones of your boot
environments.
Note the following distinctions relevant to boot environment administration:
*A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable.
*A boot environment is a bootable Oracle Solaris environment,consisting of a root dataset and,optionally,other datasets mounted underneath it. Exactly one boot environment can be active at a time.
*A clone of a boot environment is created by copying another boot environment. A clone is bootable.

NO.150 You want to configure an iSCSI target device on your system.
Select the group package required to install this functionality on your system.

storage-server

solaris-small-server

storage-avs

storage-nas

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.

NO.151 Which two options are accurate regarding the non-global zone console?

Access the non-global zone console by using the zlogin -c command.

Access the non-global zone console by using the zlogin -1 command.

Disconnect from the non-global zone console by using the ~. keys.

Disconnect from the non-global zone console by using the #. keys.

Explanation/Reference:
Explanation:
A: How to Log In to the Zone Console Use the zlogin command with the -C option and the name of the zone, for example, my-zone.
global# zlogin -C my-zone
C: To disconnect from a non-global zone, use one of the following methods.
* To exit the zone non-virtual console:
zonename# exit
* To disconnect from a zone virtual console, use the tilde (~) character and a period:
zonename# ~.

NO.152 The OpenBoot firmware controls the operation of the system before the operating system is loaded.
Which four tasks are directly controlled by the OpenBoot firmware?

Provides a list of boot entries from which to choose

Allows hardware to identify itself and load its own plug-in device driver

Loads the boot loader from the configured boot device

Performs basic hardware testing

Installs the console

Reads and executes the boot archive

Extract and executes the kernel image

OpenBoot firmware is executed immediately after you turn on your system. The primary tasks of OpenBoot firmware are to:
*Test and initialize the system hardware (D)
*Determine the hardware configuration (D) *Boot the operating system from either a mass storage device or from a network *Provide interactive debugging facilities for testing hardware and software
*Plug-in Device Drivers (B)
Most common tasks that you perform using OpenBoot
*Booting Your System
The most important function of OpenBoot firmware is to boot the system.
Note: If auto-boot? is true,the system will boot from either the default boot device or from
the diagnostic boot device depending on whether OpenBoot is in diagnostic mode. (C)
Some notable features of OpenBoot firmware.

NO.153 CORRECT TEXT
The following image properties are displayed on your system:

Which two options describe the boot environment policy property that is currently set for this
image?
All package operations are performed in a new BE set as active on the next boot.
Do not create a new BE. The install, update, uninstall, or revert operation is not performed if a new
BE is required.
If a BE is created, do not set it as the active BE on the next boot
A reboot is required for all package operations
A reboot is not required after a package operation.
For package operations that require a reboot, this policy creates a new BE set as active on the
next boot.

D,
F
image properties described below.
* be-policy
Specifies when a boot environment is created during packaging operations. The following values
are allowed:
/ default
Apply the default BE creation policy: create-backup.
/ always-new (D, F)
Require a reboot for all package operations (D) by performing them in a new BE set as active on
the next boot (F). A backup BE is not created unless explicitly requested.
This policy is the safest, but is more strict than most sites need since no packages can be added
without a reboot.

NO.154 Which two accurately describe the Solaris IPS repository?

It contains a collection of operating system patches.

It contains a collection of software packages.

All packages within an IPS package repository reside in a catalog.

It is an ISO image of the Solaris installation media.

The packages in a catalog are associated with a specific publisher.

Image Packaging System (IPS) is a new network based package management system included in Oracle Solaris 11. It provides a framework for complete software lifecycle management such as installation, upgrade and removal of software packages. IPS also enables you to create your own software packages, create and manage package repositories, and mirror existing package repositories.
Oracle Solaris software is distributed in IPS packages. IPS packages are stored in IPS package repositories, which are populated by IPS publishers.
E: The following command displays property information about the local repository.
$ pkgrepo get -s /export/repoSolaris11
SECTION PROPERTY VALUE publisher prefix solaris repository description This\ repository\ serves\ a\ copy\ of\ the\ Oracle\ Solaris\ 11\ Build\ 175b\ Package\ Repository.
repository name Oracle\ Solaris\ 11\ Build\ 175b\ Package\ Repository
repository version 4
The value of the publisher prefix specifies that solaris is to be used in the following cases:
When more than one publisher’s packages are present and no publisher is specified in the package name in the pkg command When packages are published to the repository and no publisher is specified.

NO.155 The following information is displayed for the svc:/network/ssh service: Which describes the minimum set of commands to be executed to bring the svc: /network/ssh: default service back online?

svcadm refresh svc:/network/ssh:default

svcadm restart svc:/network/ssh:default

svcadm enable svc:/system/cryptosvc

svcadm enable svc:/system/cryptosvcsvcadm enable svc:/network/ipfilter:defaultsvcadm enable svc:/network/ssh:default

svcadm enable svc:/system/cryptosvcsvcadm enable svc:/network/ipfilter:defaultsvcadm refresh svc:/network/ssh:default

svcadm restart svc:/system/cryptosvcsvcadm restart svc:/network/ipfilter:defaultsvcadm restart svc:/network/ssh:default

svcadm enable svc:/system/ssh:default

NO.156 ServerA contains two ISO images of a package repository named so1.repo.iso-a and so1.repo.iso-b respectively. You need to create a single local package repository on server that clients can connect to.
The package repository will be stored on the /export/IPS file system and named repo. The preferred publisher will be named solaris and the publisher URL will be http://serverA.example.com.
Which is the correct procedure to perform on ServerA to create the local Package repository?

cat so1.repo.iso-a sol.repo.iso-b > so1.full.isoMount the ISO image and use the rsync command to extract the contents of the ISO file to the /export/IPS file system.Set the pkg/inst_root property to / export/IPS/repo and the pkg/readonly property to true.Set the preferred publisher by using pkg set- publisher -Ghttp://pkg.oracle.com/solaris/release/ -g http”//serverA.example.com/ solaris

NO.157 Identify the two security features incorporated in the Oracle Solaris 11 Cryptographic Framework.

Layer 5 IP address encryptions

Internet protocol security

Diffie-Kerberos coaxial key encryption

Signed cryptographic plugins (providers)

Kernel support for signed antivirus plugins

The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another name for providers is plugins. The framework allows three types of plugins:
*User-level plugins – Shared objects that provide services by using PKCS #11 libraries,such as pkcs11_softtoken.so.1.
*Kernel-level plugins – Kernel modules that provide implementations of cryptographic algorithms in software,such as AES.
Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.
*Hardware plugins – Device drivers and their associated hardware accelerators. The Niagara chips,the ncp and n2cp device drivers,are one example. A hardware accelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example.

NO.158 You log in to the system as user1, then switch user to root by using the su – command. After entering the correct password, yon enter the following commands:
whoami;who am i;id
Which option correctly represents the output?

Option A

Option B

Option C

Option D

Explanation/Reference:
Explanation:
* The whoami utility displays your effective user ID as a name.
Here this would be root.
* who am i
The command who shows who is logged on.
Here this would be:
user1 console Dec 30 20:20
* The id utility displays the user and group names and numeric IDs, of the calling process, to the standard output. If the real and effective IDs are different, both are displayed, otherwise only the real ID is displayed.
Here this would be:
uid=0(root) gid=0(root)
Note:
Each UNIX proces has 3 UIDs associated to it. Superuser privilege is UID=0.
Real UID
——–
This is the UID of the user/process that created THIS process. It can be changed only if the running process has EUID=0.
Effective UID
————-
This UID is used to evaluate privileges of the process to perform a particular action. EUID can be change either to RUID, or SUID if EUID!=0. If EUID=0, it can be changed to anything.
Saved UID
———
If the binary image file, that was launched has a Set-UID bit on, SUID will be the UID of the owner of the file. Otherwise, SUID will be the RUID.

NO.159 Which command would you use to determine which package group is installed on your system?

pkg list group/system/*

pkg info

uname -a

cat /var/sadm/system/admin/CLUSTEP

The pkg info command provides detailed information about a particular IPS package.
Note: The pkginfo command does the same for any SVR4 packages you may have installed on the same system.
pkg info example: $ pkg info p7zip Name: compress/p7zip Summary: The p7zip compression and archiving utility Description: P7zip is a unix port of the 7-Zip utility. It has support for numerous compression algorithms, including LZMA and LZMA2, as well as for various archive and compression file formats, including 7z, xz, bzip2, gzip, tar, zip (read-write) and cab, cpio, deb, lzh, rar, and rpm (read-only). Category: System/Core State: Installed Publisher: solaris Version: 9.20.1 Build Release: 5.11 Branch: 0.175.0.0.0.2.537 Packaging Date: Wed Oct 19 09:13:22 2011 Size: 6.73 MB FMRI: pkg://solaris/compress/[email protected], 5.11-0.175.0.0.0.2.537:20111019T091322Z
