Question No: 11 – (Topic 1)

The root (/) file system exists on d10, which is a mirror that contains submirrors dii and di2. Which two are true if submirror d12 is taken offline? (Choose two.)

  1. The d10 mirror is in read-only mode.

  2. The d12 submirror is in read-only mode.

  3. The other submirror, d11, can also be taken offline if needed.

  4. Data redundancy is still provided due to the remaining d11 submirror.

  5. Any writes to the mirror are tracked in a dirty region log, so that d12 can be resynchronized when it is brought back online.

Answer: B,E

Question No: 12 – (Topic 1)

Under the Solaris Volume Manager software, which RAID configuration is valid for the volume containing the / (root) file system?

  1. RAID 0, consisting of drives c0t0d0 and c0t1d0

  2. RAID 1, consisting of drives c0t0d0 and c0t1d0

  3. RAID 5, consisting of drives c0t0d0, c0t1d0, and c0t2d0

  4. RAID 0 1, consisting of drives c0t0d0, c0t1d0, dt0d0, and c1d1d0

Answer: B

Question No: 13 – (Topic 1)

A user requires three file systems of the same size. The user requires the file systems to be able to remain online after a single disk failure. The user is NOT concerned about read or writes performance. The user has provided a disk array with 10 drives in it. The user requires the maximum amount of usable space from this array.

Which configuration satisfies all of the user#39;s requirements?

  1. three RAID-5 volumes of three drives each with one drive being used as a hot spare

  2. three RAID-0 volumes of three drives each with one drive being used as a hot spare

  3. three soft partitions created on a single RAID-1 volume consisting of all 10 drives

  4. three soft partitions created on a single RAID-5 volume consisting of all 10 drives

Answer: D

Question No: 14 – (Topic 1)

What are two beneficial features of soft partitions? (Choose two.)

  1. They allow a single large volume to be subdivided into more than eight segments.

  2. They improve throughput by scattering access across multiple physical volumes.

  3. They allow multiple physical volumes to be combined into a single logical volume.

  4. They allow the file system to grow as the underlying volume size increases without moving or destroying the data already stored on it.

  5. They allow a file system to grow beyond the limits of the underlying physical volume.

  6. They provide a more reliable method for storing data and improving availability.

Answer: A,D

Question No: 15 – (Topic 1)

When creating a slice for your database replicas, how much space should be allocated to the slice?

  1. 4 Mbytes in size for each replica that it will store.

  2. 8 Mbytes in size for each replica that it will store.

  3. 8 Kbytes in size for each replica that it will store.

  4. 4 Kbytes in size for each replica that it will store.

Answer: A

Question No: 16 DRAG DROP – (Topic 1)

Click the Task button.

A machine running Solaris 10 OS has the root file system mirrored using Solaris Volume Manager software. The root mirror is d10 and is made up of submirrors d11 and d12.

Submirrord11 is on c0t0d0s0, submirror d12 is on c0t1d0s0, and the state databases are on c0t0d0s3, c0t1d0s3 and c1t1d0s3. Disk c0 t1d0 has failed and has been replaced, and the machine is now booted with the new c0t1d0 disk installed.

Question No: 17 – (Topic 1)

Which two statements accurately describe hot spare usage and features? (Choose two.)

  1. A hot spare can hold data NOT in immediate use.

  2. A hot spare can improve the robustness of a RAID-0 volume,

  3. A hot spare is a slice that is functional and available, but NOT in use.

  4. A hot spare is on reserve to substitute for a failed slice in a submirror or RAID-5 volume,

  5. A hot spare is a volume that is functional and available, but NOT in use.

Answer: C,D

Question No: 18 – (Topic 1)

Which three statements accurately describe soft partitions? (Choose three.)

  1. Soft partitions are an alternative to Solaris Volume Manager software volumes for organizing disk storage.

  2. An unlimited number of soft partitions can be created from a volume.

  3. A soft partition can be grown to use any available space on a volume.

  4. A soft partition can be included in a volume and directly accessed by an application simultaneously.

  5. Soft partitions can be extended without moving or destroying data on other soft partitions.

  6. Soft partitions provide a mechanism for dividing large storage spaces into smaller, more manageable sizes.

Answer: C,E,F

Question No: 19 – (Topic 1)

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.

What is the minimum number of drives that you need to place metastate database replicas on to accomplish this?

  1. 1

  2. 2

  3. 3

  4. 4

Answer: C

Question No: 20 – (Topic 1)
