NEW QUESTION 121
Your users are experiencing delay issues while using their main application that requires connections to remote hosts. You run the command uptime and get the flowing output:
1:07am up 346 day(s), 12:03, 4 users, load average: 0.02, 0.02, 0.01
Which command will be useful in your next step of troubleshooting?

• A. arp
• B. traceroute
• C. ipadm
• D. dladm
• E. snoop

Answer: B

Explanation:
Test the remote connection with traceroute.
The Internet is a large and complex aggregation of network hardware, con-
nected together by gateways. Tracking the route one's packets follow (or finding the miscreant
gateway that's discarding your packets) can be difficult. traceroute utilizes the IP protocol `time to
live' field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along
the path to some host.
This program attempts to trace the route an IP packet would follow to some internet host by
launching UDP probe packets with a small ttl (time to live) then listening for an ICMP "time
exceeded" reply from a gateway.
Reference: man traceroute

NEW QUESTION 128
Which two options describe how to override the default boot behavior of an Oracle Solaris 11 SPARC system to boot the system to the single-user milestone?

• A. From the ok prompt. issue this command:
  boot -s
• B. From from the ok prompt, issue this command:
  boot -m milestone=s
• C. from the ok prompt, issue this command:
  boot -m milestone=single-user
• D. From the ok prompt, issue this command:
  boot -milestone=single-user
• E. From the ok prompt, issue this command:
  boot -m milestone/single-user

Answer: A,C

Explanation:
Explanation/Reference:
Explanation:
By default, Solaris will boot to the pseudo milestone "all" and start all services. This behaviour can be changed at boot time using either "-s" to reach single-user, or the new SMF option "-m milestone=XXX" (see kernel(1M) for a list of the bootable milestones) to select an explicit milestone.
Note: boot -s is the same as: boot -m milestone=single-user
with the difference being that the former is a lot less to type and is what most SysAdmins will be familiar with.

• B. It is an ISO image of the Solaris installation media.
• C. It contains a collection of software packages.
• D. It contains a collection of operating system patches.
• E. The packages in a catalog are associated with a specific publisher.

Answer: C,E

Explanation:
Explanation/Reference:
Explanation:
Image Packaging System (IPS) is a new network based package management system included in Oracle Solaris 11. It provides a framework for complete software lifecycle management such as installation, upgrade and removal of software packages. IPS also enables you to create your own software packages, create and manage package repositories, and mirror existing package repositories.
Oracle Solaris software is distributed in IPS packages. IPS packages are stored in IPS package repositories, which are populated by IPS publishers.
E: The following command displays property information about the local repository.
$ pkgrepo get -s /export/repoSolaris11
SECTION PROPERTY VALUE publisher prefix solaris repository description This\ repository\ serves\ a\ copy\ of\ the\ Oracle\ Solaris\ 11\ Build\ 175b\ Package\ Repository.
repository name Oracle\ Solaris\ 11\ Build\ 175b\ Package\ Repository
repository version 4
The value of the publisher prefix specifies that solaris is to be used in the following cases:
When more than one publisher's packages are present and no publisher is specified in the package name in the pkg command When packages are published to the repository and no publisher is specified.

NEW QUESTION 131
Your server has a ZFS storage pool that is configured as follows:

The server has two spate 140-GB disk drives: c3t5d0 c3t6d0
Which command would add redundancy to the pool1 storage pool?

• A. zpool add pool1 mirror c3t5d0 c3t6d0
• B. zpool attach pool1 c3t3d0 c3c5d0; zpoo1 attach pool1 c3t4d0 c3t6d0
• C. zpool mirror pool1 c3t5d0 c3t6d0
• D. zpool add raidz pool1 c3t5d0 c3t6d0
• E. zpool attach pool1 c3t5d0 c3t6d0

Answer: E

Explanation:
Explanation/Reference:
Explanation:
You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
Note: zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

NEW QUESTION 132
You need to migrate a UFS file system named /production_ufs to a ZFS file system named
/production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.
Which method allows you to meet both requirements?
1 . Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.
2 . When the copy is complete, /production_zfs will contain an up-to date copy of
/production_ufs

• A. Create the new zfs file system by using the zfs create -o shadow.
• B. Mirror the existing UFS file system by using SVM.After both submissions are in sync, migrate one of the submissions to a ZFS file System by using Live Upgrade.
• C. Create the new ZFS file system by using zfs create import to import data from the existing UFS file system into the new ZFS file system
• D. Create a new Boot Environment. Create the ZFS file system. Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.
• E. Create a snapshot of the UFS file system. Create the new ZFS file system. Use cpio to copy data from the snapshot to the new ZFS file system.

Answer: A

Explanation:
Migrating Data With ZFS Shadow Migration
ZFS shadow migration is a tool you can use to migrate data from an existing file system to a new file system. A shadow file system is created that pulls data from the original source as necessary.
You can use the shadow migration feature to migrate file systems as follows:
* A local or remote ZFS file system to a target ZFS file system
* A local or remote UFS file system to a target ZFS file system
Shadow migration is a process that pulls the data to be migrated:
* Create an empty ZFS file system.
* Set the shadow property on an empty ZFS file system, which is the target (or shadow) file system, to point to the file system to be migrated.
For example:
# zfs create -o shadow=nfs://system/export/home/ufsdata users/home/shadow2
* Data from file system to be migrated is copied over to the shadow file system.
