serves as the interface between the SMF repository and the user to ensure that a consistent,picture of the repository is presented to the user.

  1. repository.db

  2. service manifest

  3. svc.startd

  4. svc.configd

Answer: D Explanation:

SVC.CONFIGD is the repository daemon responsible for maintaining /etc/svc/repository.db. The repository.db must come clean during this integrity check otherwise it is a quot;no goquot; for usual boot sequence to run level 3. The repository may get corrupted due to various hardware issues,software bugs,disk write failures,etc.

Note: When svc.configd(1M),the Solaris Repository Daemon,is started,it does an integrity

check of the smf(5) repository,stored in /etc/svc/repository.db. This integrity check can fail due to a disk failure,the database file being corrupted either due to a hardware bug,a software bug,or an accidental overwrite. If the integrity check fails,svc.configd will write a message to the console.

You have a user that needs to use the cron tool to schedule some repetitive tasks. When the user enters the crontab -e command in a terminal window,the following error appears:

crontab: you are not authorized to use cron. Sorry

In order to troubleshoot this issue,in what directory would you start your invest

  1. /etc/cron.d

  2. /var/spool/cron

  3. /var/spool/cron/crontable

  4. /var/spool/cron/atjobs

Answer: A Explanation:

crontab: you are not authorized to use cron. Sorry.

This message means that either the user is not listed in the cron.allow file (if the file exists),or the user is listed in the cron.deny file.

You can control access to the crontab command by using two files in the /etc/cron.d directory: cron.deny and cron.allow. These files permit only specified users to perform crontab command tasks such as creating,editing,displaying,or removing their own crontab files.

The cron.deny and cron.allow files consist of a list of user names,one user name per line.

A datalink can best be described as .

  1. a driver for a Network Interface Card

  2. the software connecting the Internet Layer and the Physical Layer

  3. a device that provides Classless Inter-Domain Routing

  4. a logical object used for IP Multipathing

Answer: D Explanation:

The command dladm is used to configure data-link interfaces in Sun Solaris. A configured

data-link is represented in the system as interface that can be used for TCP/IP. Each data- link relies on either a single network device or an link aggregation device to send amp; recieve packets.

Network interfaces provide the connection between the system and the network. These interfaces are configured over data links,which in turn correspond to instances of hardware devices in the system.

In the current model of the network stack,interfaces and links on the software layer build on the devices in the hardware layer. More specifically,a hardware device instance in the hardware layer has a corresponding link on the data-link layer and a configured interface on the interface layer. This one-to-one relationship among the network device,its data link,and the IP interface is illustrated in the figure that follows.

The following command is executed on the disk: zpool create pool1 c3t3d0s0

What is the result of executing this command?

  1. A zpool create error is generated.

  2. A 1-GB ZFS file system named /pool1 is created.

  3. A 15.97-GB storage pool named pool1 is created.

  4. The disk will contain an EFI disk label.

Answer: B

You want the system to generate an email notification each time one of the services has changed its state. Which option would send an email message to the system administrator whenever a service changes to the maintenance state?

  1. Use the setsc command in ALOM to enable the mail alerts to be sent to a specified email address whenever the fault management facility detects a service change to the maintenance state.

  2. Make an entry in the /etc/syslog.conf file to instruct syslogd to send an email alert when it receives a message from the SMF facility that a service has changed to the maintenance state.

  3. Use the svccfg setnotify command to create a notification and send an email when a service enters the maintenance state.

  4. Use the scvadm command to enable the notification service. Set the -g maintenance option on the netnotify service to send an email when a service enters the maintenance state.

    Answer: C Explanation:

    This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally,you would only select SNMP if you already have SNMP configured for some other reason.

    By default,SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring,you can configure additional traps for other state transitions.

    1. Become an administrator or assume a role that includes the Service Management rights profile.

    2. Set notification parameters.


      The following command creates a notification that sends email when transactions go into the maintenance state

      # /usr/sbin/svccfg setnotify -g maintenance mailto:sysadmins@example.com

      Which best describes the svc:/system/boot-config service?

      1. It is used to change the milestone on a system.

      2. It is used to set the default run level of the system.

      3. It provides the parameters used to set the system to automatically perform a fast or slow reboot.

      4. When the service is enabled,the system performs a fast reboot by default; when it is disable the system performs a slow reboot by default.

Answer: C Explanation:

Starting with the Oracle Solaris 11 Express release,Fast Reboot is supported on the SPARC platform,as well as the x86 platform. On both platforms,this feature is controlled by the SMF and implemented through a boot configuration service,svc:/system/boot-config.

The boot-config service provides a means for setting or changing the default boot configuration parameters.

The fastreboot_default property of the boot-config service enables an automatic fast reboot of the system when either the reboot or the init 6 command is used. When the config/fastreboot_default property is set to true the system automatically performs a fast reboot,without the need to use the reboot -f command. By default,this property#39;s value is set to false on the SPARC platform and to true on the x86 platform.

Question No: 68 – (Topic 1)

You are troubleshooting a newly installed desktop Oracle Solaris 11 system with a single network interface. From this system,you can connect to other systems within the company intranet,but cannot access any external services (such as websites and email),even when using IP addresses.

Examining the routing table confirms that the default route to is missing. DHCP is not used at this site. Which two commands will temporarily mid permanently configure the default route?

  1. ipadm set-gateway

  2. route add default

  3. ipadm set-default

  4. dladm route-add -d

  5. echo gt;/etc/gateway


Answer: B,F Explanation:

B: Setting the default route on Solaris is easy. If you are trying to just set the route temporarily you can use the route command:

Route add default lt;ipaddressgt; Example:

Route add default

Note: Route command manipulates the kernel routing tables. Routing is the process of forwarding a packet from one computer to another. It is based on the IP address in the IP packet header and netmask.

F: If you want the route to be persisted when you reboot the system,you will need to set the route in the /etc/defaultrouter file.

/etc/defaultrouter Example:

Echo gt; /etc/defaultrouter

  3. pkg rebuild-index p7zip

  4. pkg revert p7zip

  5. pkg uninstsll p7zip

  6. pkg install p7zip

  7. pkg install -no-backup-be p7sip

  8. pkg refresh p7zip

Answer: D Explanation:

Use the pkg revert command to restore files to their as-delivered condition.

Question No: 70 – (Topic 1)

Which network protocol provides connectionless,packet-oriented communication between applications?

  1. TCP

  2. UDP

  3. IP

  4. ICMP

  5. NFS

  6. IPSec

Answer: B Explanation:

The User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite,the set of network protocols used for the Internet. With UDP,computer applications can send messages,in this case referred to as datagrams,to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths.

Compared to TCP,UDP is a simpler message-based connectionless protocol.
