CompTIA SK0-005 Online Questions & Answers

• Question 331:

  A technician is laying out a filesystem on a new Linux server. Which of the following tools would work BEST to allow the technician to increase a partition's size in the future without reformatting it?

  A. LVM
  B. DiskPart
  C. fdisk
  D. Format
  A. LVM

  ---

  Explanation

  LVM (Logical Volume Manager) is a tool that allows the technician to increase a partition's size in the future without reformatting it on a Linux server. LVM creates logical volumes that can span across multiple physical disks or partitions and

  can be resized dynamically without losing data. LVM also provides other features such as snapshots, encryption, and RAID. DiskPart, fdisk, and Format are tools that can be used to partition and format disks, but they do not allow increasing

  a partition's size without reformatting it.

• Question 332:

  Which of the following will protect critical data during a natural disaster?

  A. Off-site storage
  B. Life-cycle management
  C. Environmental controls
  D. Data-at-rest encryption
  A. Off-site storage

  ---

  Explanation

  Off-site storage involves storing data backups in a physically separate location from where the servers and primary data reside. This protects critical data in case the main site is damaged or destroyed due to a natural disaster, such as floods,

  fires, or earthquakes. Off- site storage can be in the form of cloud storage or physical tapes stored in a geographically distant location. Off-site storage (Answer A):It ensures that a company's critical data remains accessible even if the local

  infrastructure is compromised. This is a common part of disaster recovery planning and is crucial for business continuity. Life-cycle management (Option B): While important for managing data from creation to deletion, it does not specifically

  protect data during disasters. Environmental controls (Option C): These manage physical conditions like temperature and humidity but do not address the risk of data loss during disasters. Data-at-rest encryption (Option D): Encryption

  protects the confidentiality of stored data but does not ensure availability in the event of a disaster.

  This topic is covered underSK0-005 Objective 4.1:

  Summarize disaster recovery methods and concepts.

• Question 333:

  A server administrator mounted a new hard disk on a Linux system with a mount point of /newdisk. It was later determined that users were unable to create directories or files on the new mount point. Which of the following commands would successfully mount the drive with the required parameters?

  A. echo /newdisk >> /etc/fstab
  B. net use /newdisk
  C. mount -o remount, rw /newdisk
  D. mount -a
  C. mount -o remount, rw /newdisk

  ---

  Explanation

  The administrator should use the command mount -o remount,rw /newdisk to successfully mount the drive with the required parameters. The mount command is used to mount file systems on Linux systems. The -o option specifies options for mounting file systems. The remount option re-mounts an already mounted file system with different options. The rw option mounts a file system with read-write permissions. In this case, /newdisk is a mount point for a new hard disk that was mounted with read-only permissions by default. To allow users to create directories or files on /newdisk, the administrator needs to re-mount

• Question 334:

  A systems administrator needs to back up changes made to a data store on a daily basis during a short time frame. The administrator wants to maximize RTO when restoring data. Which of the following backup methodologies would best fit this scenario?

  A. Off-site backups
  B. Full backups
  C. Differential backups
  D. Incremental backups
  D. Incremental backups

  ---

  Explanation

  An incremental backup is a backup method that only backs up the files that have changed since the last backup, whether it was a full or an incremental backup. An incremental backup can save disk space and time, as it only copies the new or modified data. An incremental backup can also improve the RTO (Recovery Time Objective), which is the maximum acceptable time to restore data after a disaster. This is because an incremental backup can restore data faster than a full or a differential backup, as it only needs to apply the latest changes to the previous backup1.

• Question 335:

  A hardware technician is installing 19 1U servers in a 42-unit rack. The technician needs to allocate enough space per server for optimal air flow. Which of the following unit sizes should be allocated per server?

  A. 1U
  B. 2U
  C. 3U
  D. 4U
  A. 1U

  ---

  Explanation

  This unit size would be sufficient to allocate per server for optimal airflow, as rack mount servers and racks are designed for airflow with all panels and bezels on and all U's filled. Leaving gaps between servers or removing panels and covers may disrupt the airflow and cause overheating. The technician should also ensure that the airflow is front to back, as vertical airflow is likely to be ineffective. Additionally, the technician should use blanking panels, fan trays, or other devices to manage hot spots and improve circulation.

• Question 336:

  Which of the following, if properly configured, would prevent a user from installing an OS on a server? (Choose two)

  A. Administrator password
  B. Group Policy Object
  C. Root password
  D. SELInux
  E. Bootloader password
  F. BIOS/UEFI password
  E. Bootloader password
  F. BIOS/UEFI password

  ---

  Explanation

  These are two methods that can prevent a user from installing an OS on a server if properly configured. A bootloader password is a password that protects the bootloader from unauthorized access or modification. The bootloader is a program that loads the operating system into memory when the system boots up. If a user does not know the bootloader password, they cannot change the boot order or boot from another device such as a CD-ROM or USB drive that contains an OS installation media. A BIOS/UEFI password is a password that protects the BIOS (Basic Input Output System) or UEFI (Unified Extensible Firmware Interface) from unauthorized access or modification. The BIOS or UEFI is a firmware that initializes and configures the hardware components of the system before loading

• Question 337:

  A technician is connecting a Linux server to a share on a NAS. Which of the following is the MOST appropriate native protocol to use for this task?

  A. CIFS
  B. FTP
  C. SFTP
  D. NFS
  D. NFS

  ---

  Explanation

  The most appropriate native protocol to use for connecting a Linux server to a share on a NAS is NFS. NFS (Network File System) is a protocol that allows file sharing and remote access over a network. NFS is designed for Unix-like operating systems, such as Linux, and supports features such as symbolic links, hard links, file locking, and file permissions. NFS uses mount points to attach remote file systems to local file systems, making them appear as if they are part of the local file system. NFS can provide fast and reliable access to files stored on a NAS (Network Attached Storage), which is a device that provides centralized storage for network devices.

• Question 338:

  A server administrator is testing a disaster recovery plan. The test involves creating a downtime scenario and taking the necessary steps. Which of the following testing methods is the administrator MOST likely performing?

  A. Backup recovery
  B. Simulated
  C. Tabletop
  D. Live failover
  B. Simulated

  ---

  Explanation

• Question 339:

  Which of the following license types most commonly describes a product that incurs a yearly cost regardless of how much it is used?

  A. Physical
  B. Subscription
  C. Open-source
  D. Per instance
  E. Per concurrent user
  B. Subscription

  ---

  Explanation

  A subscription license is a type of license that grants the user the right to use a product or service for a fixed period of time, usually a year. The user pays a recurring fee, regardless of how much they use the product or service. Subscription

  licenses are common for cloud- based software and services, such as Microsoft 3651 or DocuSign2.

• Question 340:

  A technician wants to duplicate a physical server to a remote private cloud for disaster recovery purposes. Which of the following techniques would best accomplish this goal?

  A. V2V
  B. P2V
  C. V2P
  D. P2P
  B. P2V

  ---

  Explanation

  P2V (Physical to Virtual)refers to converting a physical server into a virtual machine, which can then be deployed to a remote cloud environment. This is the best method for duplicating a physical server to a virtual environment for disaster

  recovery. P2V (Answer B):This is the process of converting a physical server to a virtual machine for migration to the cloud.

  V2V (Option A):Refers to virtual-to-virtual migration, which is not applicable in this case.

  V2P (Option C):Refers to converting a virtual machine back to physical, which is not needed here.

  P2P (Option D):Physical-to-physical migration is not relevant for cloud-based disaster recovery.
