B. At least two state database replicas per RAID-1 volume.

C. One state database replicas per RAID-1 volume.

D. At least five state database replicas per RAID-1 volume.

Correct Answer: B

Question 2

A. The maximum number that can be specified depends on the data type.

B. A minimum of two can be specified.

C. A maximum of four can be specified.

D. The maximum number that can be specified depends on the system type.

E. A minimum of one can be specified.

Correct Answer: A,E

Question 3

With the Solaris OS, you are required to reserve swap space prior to executing any process. This requires the available of swap space. The required amount of swap space varies from system to system. Which two statements about available swap space requirements are true? (Choose two.)

A. It must be twice as large as the installed physical RAM.

B. It must be spread across all the installed disks in the system. If there are two disks in the system, there must be a swap slice on each disk.

C. It does not require physical disk space.

D. It must be spread across all the controllers installed in the system. If the system has two controllers, each controller must have a disk with a swap slice.

E. It must be sufficient to supplement physical RAM to meet the needs of concurrently running processes.

Correct Answer: C,E

Question 4

Given the following entry in /etc/nsswitch.conf: hosts: nis [NOTFOUND=return] files Which two statements are true? (Choose two.)

A. If the NIS map gives a "no such entry" response, the system will search local files for the host.

B. If the NIS map does NOT respond or is unavailable, the system will stop searching for the host.

C. If the NIS map does NOT respond or is unavailable, the system will search local files for the host.

D. If the NIS map gives a "no such entry" response, the system will stop searching for the host.

E. If the local files cannot be found, the system will search the NIS map for the host.

Correct Answer: C,D

Question 5

You have three applications from three different vendors, but only one system to run them on. Each application will require different OS patches to be installed. The problem you will encounter, if you load all of these applications on the same server, is that the vendor will not support the application if it runs on anything but the recommended environment. Which answer provides a solution?

A. Run each application in a separate non-global zone. Patch the non-global zones with the most current patch versions.

B. Run each application in a separate non-global zone. Patch each zone separately.

C. Zones will not work in this scenario- use domains.

D. Run each application in a zone. Install one application in the global-zone and patch it with the most current patch versions allowed. Do not patch the non-global zones.

Correct Answer: B

Question 6

Given:
# rpcinfo -p |grep rusersd 100002 2 tcp 32776 rusersd 100002 3 tcp 32776 rusersd 100002 2 udp 32786 rusersd 100002 3 udp 32786 rusersd
Which three statements are true? (Choose three.)

A. rusersd is registered with rpcbind.

B. The process identifiers (pids) of rusersd are 32776 and 32786.

C. rusersd uses TCP and UDP protocols.

D. rusersd always uses port 100002.

E. rusersd is currently using ports 32776 and 32786.

Correct Answer: A,C,E

Question 7

Given the default coreadm settings in the local zone and the following configuration for the global zone:
# coreadm global core file pattern: /var/core/core.%f.%p global core file content: all init core file pattern: core.%f.%p init core file content: default global core dumps: enabled per-process core dumps: enabled global setid core dumps: disabled per-process setid core dumps: disabled global core dump logging: enabled
This configuration will cause two core files to be generated and saved when a process in the local zone terminates abnormally.
Where are the two core files saved? (Choose two.)

A. in the process current working directory as core

B. in the global zone as core.%f.%p in /var/core

C. in the process current working directory as core.%f.%p

D. in the local zone as core.%f.%p in /var/core

Correct Answer: A,B

Question 8

You are configuring a new system. You would like the system to be able to boot unattended, even if its boot disk fails. You decide to mirror the root file systems using Solaris Volume Manager software.
Assume one (1) metastate database replica per drive.
What is the minimum number of drives that you need to place metastate database replicas on to accomplish this?

A. 4

B. 3

C. 1

D. 2

Correct Answer: B

Question 9

Given the line taken from the syslogd daemon configuration file: mail.debug /var/adm/messages

A. The mail.debug messages are logged remotely if a remote host is configured in the /etc/inet/hosts file.

B. The mail.debug messages are logged locally in the /var/adm/messages file, regardless of any loghost alias.

C. The mail.debug messages are not logged at all because the /var/adm/messages file is for kernel messages only.

D. Assuming a remote loghost is configured, the mail.debug messages are logged locally and remotely.

Correct Answer: B

Question 10
