Answer : D

An M represents a modified file or directory, an R is a renamed filesystem objects.

Answer : A, B, E

A: ZFS is the default root file system.

UFS is a supported legacy file system, but it is not supported as a bootable root file system.

E:

If your system has more than one OS installed on the system or more than one root boot environment in a ZFS root pool, you can boot from these boot environments for both SPARC and x86 platforms:

* Starting with the Solaris 10 10/08 release for a SPARC based system, you can boot a ZFS root file system in a ZFS pool. For ZFS root pools, you can list the available boot environments with the boot command with the -L option. You can then choose a boot environment and use the OBP boot command with the -Z option to boot that boot environment.

* Starting with the Solaris 10 1/06 release for x86 based systems, a GRUB boot menu provides the interface for booting between different boot environments.

Note:

* The name originally stood for 'Zettabyte File System' but today does not stand for anything.

Incorrect:

Not C: Mirroring is not enabled by default.

Not D: Alternate boot environments

If you want to create a backup of an existing boot environment, for example, prior to modifying the original boot environment, you can use the beadm command to create and mount a new boot environment that is a clone of your active boot environment. This clone is listed as an alternate boot environment in the GRUB menu for x86 systems or in the boot menu for SPARC systems.

Answer : E

Through the zonecfg utility, the file-mac-profile can be set to one of the following values (see note below). All of the profiles except none will cause the /var/pkg directory and its contents to be read-only from inside the zone.

* none

Standard, read-write, non-global zone, with no additional protection beyond the existing zones boundaries. Setting the value to none is equivalent to not setting file-mac-profile property.

* strict

* fixed-configuration

Permits updates to /var/* directories, with the exception of directories that contain system configuration components.

IPS packages, including new packages, cannot be installed.

Persistently enabled SMF services are fixed.

SMF manifests cannot be added from the default locations.

Logging and auditing configuration files can be local. syslog and audit configuration are fixed.

* flexible-configuration

Note:

zonecfg file-mac-profile Property

By default, the zonecfg file-mac-profile property is not set in a non-global zone. A zone is configured to have a writable root dataset.

In a solaris read-only zone, the file-mac-profile property is used to configure a read-only zone root. A read---only root restricts access to the runtime environment from inside the zone.

Answer : A, C, D

The following table lists different tasks for planning the network configuration.

* (A) Identify the hardware requirements of your planned network topology.

Determine the types of equipment that you need for your network site.

*(C) Determine the type of IP addresses to use and obtain registered IP addresses.

Select whether you are deploying a purely IPv4 network, an IPv6 network, or a network that uses both types of IP addresses. Obtain unique IP addresses to communicate to public networks in the Internet.

* (D) Determine a naming scheme to identify the hosts in the network as well as the name service to use.

Create a list of names to assign to the systems on the network and decide whether to use NIS, LDAP, DNS, or the network databases in the local /etc directory.

* If necessary, establish administrative subdivisions and design a strategy for subnets.

Decide if your site requires that you divide your network into subnets to service administrative subdivisions

* Determine where to place routers in the network design.

If your network is large enough to require routers, create a network topology that supports them.

* Decide whether to create virtual networks in the overall network configuration scheme.

You might need to create virtual networks within a system to reduce the hardware footprint of your network.

Answer : A, C, D

Incorrect:

Not B: With a single vendor providing all the elements for an application platform, finger pointing is eliminated and problem resolution takes less time.

Note:

* Oracle's product research and engineering expertise spans the entire stack --- from storage, networks, compute and operating systems, to middleware, enterprise applications and

databases --- and is integrated and validated to work together to take the guesswork out of deploying complex solutions.

* Oracle is the only high technology company with all the software and hardware components to deliver an infrastructure that can transform and streamline business operation. Indeed, Oracle's application-to-disk stack is so well integrated and tuned that it provides less risk, better performance, and easier management for application environments

* Oracle's end-to-end solution stack includes Oracle's innovative servers and storage systems, the industry's only end-to-end virtualization portfolio, robust Oracle Solaris and Oracle Linux operating environments, Oracle Database, middleware, premier enterprise applications, and industry-leading management tools. For years, Oracle has strived to integrate, test, and certify these technologies to work together to deliver the functionality, performance, security, and reliability companies can depend on to get the job done.
