Correct Option: B

What is the process that writes physical address information to a disk

  1. Concatenating

  2. Formatting

  3. Partitioning

  4. Striping


Correct Option: B

AI Explanation

To answer this question, you need to understand the process of writing physical address information to a disk.

Option A) Concatenating - This option is incorrect. Concatenating refers to combining multiple strings or data elements into a single string or data structure. It is not directly related to writing physical address information to a disk.

Option B) Formatting - This option is correct. Formatting is the process of preparing a storage device, such as a disk, to store data. During the formatting process, the disk is divided into tracks and sectors, and the necessary data structures are created to organize and manage the storage space. This includes writing the physical address information to the disk.

Option C) Partitioning - This option is incorrect. Partitioning refers to dividing a physical storage device into multiple logical sections or partitions. It is not directly related to writing physical address information to a disk.

Option D) Striping - This option is incorrect. Striping is a technique used in disk arrays or RAID systems to spread data across multiple disks. It involves dividing data into small segments and writing them to different disks in parallel. It is not directly related to writing physical address information to a disk.

The correct answer is B) Formatting. This option is correct because formatting is the process that writes physical address information to a disk, along with other necessary data structures, to prepare it for storing data.

  1. Must be able to restart their network within 4 hours

  2. Must be able to restart their servers within 4 hours

  3. Must be able to resume production within 4 hours

  4. No more than 4 hours of production data can be lost


Correct Option: D

What is the protocol used by a Windows client to communicate with a NAS device?

  1. CIFS

  2. FCP

  3. NFS

  4. SCSI


Correct Option: A

AI Explanation

To answer this question, you need to understand the protocols used for network file sharing.

Option A) CIFS - This option is correct because the Common Internet File System (CIFS) is the protocol used by a Windows client to communicate with a NAS (Network Attached Storage) device. CIFS allows the client to access files and folders on the NAS device over a network.

Option B) FCP - This option is incorrect. Fibre Channel Protocol (FCP) is a protocol used for storage area networks (SANs), not for communication between a Windows client and a NAS device.

Option C) NFS - This option is incorrect. Network File System (NFS) is a protocol used for file sharing between UNIX-like systems. While it is possible for a Windows client to communicate with a NAS device using NFS, it is not the most common protocol used in Windows environments.

Option D) SCSI - This option is incorrect. Small Computer System Interface (SCSI) is a protocol used for connecting peripheral devices, such as hard drives, to a computer. It is not specifically used for communication between a Windows client and a NAS device.

The correct answer is A) CIFS. This option is correct because CIFS is the protocol used by a Windows client to communicate with a NAS device.

  2. Data store and bitmap store

  3. Data store and tag RAM

  4. Tag RAM and dirty store
