Solaris 9 To 11 Service Start-up

1. Which of the following commands can be used to change the run levels in Solaris 9?

Init

Runlevel

Scvs

Svcadm

The "Init" command can be used to change the run levels in Solaris 9.

Explanation

The "Init" command can be used to change the run levels in Solaris 9.

2. Service Management Facility was introduced from:

Solaris 2.9

Sun OS 5.8

Oracle Solaris 10

Oracle Solaris 11

Service Management Facility (SMF) was introduced in Oracle Solaris 10. SMF is a feature in the Solaris operating system that manages system and application services. It provides a flexible and reliable framework for managing services, allowing administrators to start, stop, and monitor services easily. SMF improves system availability by automatically restarting failed services and provides dependency management for services. It also offers a unified and consistent interface for managing services across different versions of Solaris.

3. This output is taken from a Oracle Solaris 11 system immediately after installation, selecting the only available defaults with relations to file systems: UWINPro@solaris12a:/etc/init.d$ df -n / : zfs /devices : devfs /dev : dev /system/contract : ctfs /proc : proc /etc/mnttab : mntfs /system/volatile : tmpfs /system/object : objfs /etc/dfs/sharetab : sharefs /lib/libc.so.1 : lofs /dev/fd : fd /var : zfs /tmp : tmpfs /export : zfs /export/home : zfs /export/home/don : zfs /rpool : zfs /home/don : lofs What is the default root file system for Oracle Solaris 11?

UFS

UDF

HSFS

ZFS

The output of the "df -n" command shows the file systems that are currently mounted on the Oracle Solaris 11 system. Among the listed file systems, the "/ (root)" file system is shown as "zfs". This indicates that the default root file system for Oracle Solaris 11 is ZFS (Zettabyte File System).

3

The answer is 3 because the scripts shown belong to run level 3 and start the services that are started in run level 3.

Explanation

The answer is 3 because the scripts shown belong to run level 3 and start the services that are started in run level 3.

5. Svc:/network/routing/rip:quagga svc:/application/graphical-login/cde-login:default The logs for all these facilities are stored in the directory:

/etc / svc

/lib /svc

/var /svc

/usr /svc

The correct answer is /var/svc. The logs for all the mentioned facilities are stored in the /var/svc directory.

Explanation

The correct answer is /var/svc. The logs for all the mentioned facilities are stored in the /var/svc directory.

6. Based on this output: cd /var/svc/manifest/network/routing # ls legacy-routing.xml quagga.xml ripng.xml ndp.xml rdisc.xml route.xml Which of the following statements is correct?

All xml files for all service instances are stored in /var/svc/manifest/network/routing

All xml files for the service routing is stored in /var/svc/manifest/network/routing

An xml file itself can start a service

None of the above

All xml files for the service routing is stored in /var/svc/manifest/network/routing. This is indicated by the output provided, which shows multiple xml files in the /var/svc/manifest/network/routing directory. Since the question specifically asks about the service routing, it suggests that the xml files in that directory are related to this specific service. Therefore, the correct statement is that all xml files for the service routing are stored in /var/svc/manifest/network/routing.

Explanation

All xml files for the service routing is stored in /var/svc/manifest/network/routing. This is indicated by the output provided, which shows multiple xml files in the /var/svc/manifest/network/routing directory. Since the question specifically asks about the service routing, it suggests that the xml files in that directory are related to this specific service. Therefore, the correct statement is that all xml files for the service routing are stored in /var/svc/manifest/network/routing.

7. Restore_repository is a script used to restore a damaged repository. This script is found in the directory:

/ lib /svc/repository

/var/svc /bin

/lib /svc/bin

/etc /bin

The correct answer is /lib /svc/bin. This is because the script "restore_repository" is found in the directory /lib /svc/bin.

Explanation

The correct answer is /lib /svc/bin. This is because the script "restore_repository" is found in the directory /lib /svc/bin.

8. Which of the following statements are correct? (2 corrent answers)

SMF starts after kernel initialization phase of boot process by svc.startd

FMRI starting with lrc is found only in Solaris 9

The command ‘svcadm start’ will start a service in Oracle Solaris 11

Boot programming phase starts after boot PROM phase

The first statement is correct because SMF (Service Management Facility) starts after the kernel initialization phase of the boot process, and it is started by the svc.startd process.

The fourth statement is also correct because the boot programming phase does indeed start after the boot PROM phase.

Explanation

The first statement is correct because SMF (Service Management Facility) starts after the kernel initialization phase of the boot process, and it is started by the svc.startd process.

The fourth statement is also correct because the boot programming phase does indeed start after the boot PROM phase.

Oracle Solaris 8

Oracle Solaris 11

The given output is from the rc* directories in the /etc directory. The presence of the rcS.d directory, which contains startup and shutdown scripts, is an indication that this is from a version of Oracle Solaris that uses the System V init system. This init system was used in Oracle Solaris 10, Oracle Solaris 9, and Oracle Solaris 8. However, the presence of the rc2.d directory, which contains system startup scripts, suggests that this is specifically from Oracle Solaris 11, as Oracle Solaris 10 and earlier versions did not have an rc2.d directory. Therefore, the correct answer is Oracle Solaris 11.

Solaris 11

The output of the ls -l command shows the file permissions, number of links, owner, group, file size, and modification date of each file in the /etc/init.d directory. The presence of the "UWINPro@solaris12a:" indicates that the command was run on a Solaris system. The answer "Solaris 11" is correct because the output matches the format and style of file listings in Solaris 11.

13. Svc:/network/routing/rip:quagga svc:/application/graphical-login/cde-login:default Which of the following statements are correct? (2 correct answers)

Both of these are Fault Management Resource Identifiers

Network and Application are service categories

Network and Application are instances of services routing and graphical-login

Rip:quagga is started by legacy run control scripts

Both of these statements are correct. "Fault Management Resource Identifiers" refer to the specific services that are responsible for managing and monitoring faults in a system. "Network" and "Application" are service categories that categorize different types of services.

14. Svc:/network/routing/rip:quagga svc:/application/graphical-login/cde-login:default Select the wrong statements from the following:

Cde-login is not the only instance for the service graphical-login

Quagga is a service of instance routing

Svcadm enable –t svc:/network/routing/rip:quagga will run this service until shutdown

Graphical-login is a service

The statement "quagga is a service of instance routing" is incorrect. Quagga is a routing software suite, not a service of instance routing.

Explanation

The statement "quagga is a service of instance routing" is incorrect. Quagga is a routing software suite, not a service of instance routing.
