B: How to Migrate an Existing native Non-Global Zone

Use the V2V process to migrate an existing zone on your Solaris 10 system to a solaris10 brand zone on a system running the Oracle Solaris 11 release.

C: How to Install the solaris10 Branded Zone

A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand.

Correct Answer: A

Network configuration in Oracle Solaris 11 includes

* Generic datalink name assignment ?Generic names are automatically assigned to datalinks using the net0, net1, netN naming convention, depending on the total number of network devices that are on the system

Note: There is no upgrade path from Oracle Solaris 10 to Oracle Solaris 11. You must perform a fresh installation.

Correct Answer: B

Note: # route -p add -host destination-IP gateway-IP -static where destination-IP and gateway-IP are IPv4 addresses of the host to be used as a target.

For example, you would type the following to specify the target system 192.168.10.137, which is on the same subnet as the interfaces in IPMP group itops0:

$ route -p add -host 192.168.10.137 192.168.10.137 -static This new route will be automatically configured every time the system is restarted. If you want to define only a temporary route to a target system for probe-based failure detection, then do not use the -p option.

Correct Answer: E

zfs snapshot [-r] [-o property=value] ... filesystem@snapname|volume@snapname Creates a snapshot

with the given name. All previous modifications by successful system calls to the file system are part of the

snapshot

zfs clone [-p] [-o property=value] ... snapshot filesystem|volume Creates a clone of the given snapshot.

Note:

Because snapshots are fast and low overhead, they can be used extensively without great concern for

system performance or disk use .

With ZFS you can not only create snapshot but create a clone of a snapshot. A clone is a writable volume or file system whose initial contents are the same as the dataset from which it was created. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional disk space. In addition, you can snapshot a clone.

A clone is a writable volume or file system whose initial contents are the same as the original dataset. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional space.

Clones can only be created from a snapshot. When a snapshot is cloned, it creates an implicit dependency between the parent and child.

Correct Answer: AB

A: Non-global zones can not utilize DHCP (neither client nor server). B (not C): By default, non-global zones will be configured with a shared IP functionality. What this means is that IP layer configuration and state is shared between the zone you're creating and the global zone. This usually implies both zones being on the same IP subnet for each given NIC.

Note: A zone is a virtual operating system abstraction that provides a protected environment in which applications run. The applications are protected from each other to provide software fault isolation. To ease the labor of managing multiple applications and their environments, they co-exist within one operating system instance, and are usually managed as one entity.

The original operating environment, before any zones are created, is also called the "global zone" to distinguish it from non-global zones, The global zone is the operating system instance.

Incorrect answer:

E: Exclusive-IP zones can use IPMP. IPMP is configured the same way in an exclusive-IP zone as it is on

a system not using zones.

For shared-IP zones, IPMP can be configured in the global zone.

F: Full IP-level functionality is available in an exclusive-IP zone.

An exclusive-IP zone has its own IP-related state.

An exclusive-IP zone is assigned its own set of data-links using the zonecfg command. The zone is given a

data-link name such as xge0, e1000g1, or bge32001, using the physical property of the net resource. The

address property of the net resource is not set.

Note that the assigned data-link enables the snoop command to be used.

The dladm command can be used with the show-linkprop subcommand to show the assignment of data-links to running exclusive-IP zones.
