• Question 482:

• Question 483:

  A company downloads a large number of files over the internet daily. The company needs a way to ensure the files have not been modified or corrupted during the download process. Which of the following should the company do to verify the files?

  A. Clear browsing data
  B. Install SSL certificates
  C. Check the hash value
  D. Use trusted sources
  C. Check the hash value

  ---

  Explanation

  Checking the hash value (such as MD5, SHA-1, or SHA-256) is the best way to verify file integrity after downloading. A hash function generates a unique string for a file. If even a single bit in the file is changed, the hash value will be different.

  Many software vendors provide hash values (checksums) on their websites to help users confirm that the files were downloaded without corruption or tampering.

  Option A: Clear browsing data, Incorrect. Clearing browsing data does not affect downloaded files or their integrity.

  Option B: Install SSL certificates, Incorrect. SSL certificates encrypt data transmission but do not verify the integrity of downloaded files. Option D: Use trusted sources, While downloading files from trusted sources reduces the risk of

  corruption, it does not verify file integrity.

• Question 484:

  Which of the following ls command options is used to display hidden files and directories?

  A. -a
  B. -s
  C. -lh
  D. -t

• Question 485:

  Due to special job responsibilities, an end user needs the ability to edit the properties of Windows system files. The user has already been granted local administrator privileges.

  Which of the following Control Panel utilities should be used to provide easy access to the files?

  A. File Explorer Options
  B. Ease of Access
  C. Indexing Options
  D. Administrative Tools
  D. Administrative Tools

  ---

  Explanation

  The correct answer is Administrative Tools (Option D), which provides access to several system utilities, including those needed for managing system files and settings. Since the user already has local administrator privileges, this would allow

  them to edit system properties efficiently. File Explorer Options (Option A) manage general file display settings but do not provide administrative access. Ease of Access (Option B) is related to accessibility settings, not file management.

  Indexing Options (Option C) control how files are indexed for search, but are unrelated to system file editing.

• Question 486:

  A technician has verified that a user's computer has a virus, and the antivirus software is out Of date. Which of the following steps should the technician take NEXT?

  A. Quarantine the computer.
  B. use a previous restore point,
  C. Educate the end user about viruses
  D. Download the latest virus definitions
  D. Download the latest virus definitions

  ---

  Explanation

  This will ensure that the antivirus software is up-to-date, and can detect any new viruses that may have been released since the last virus definition update.

  The CompTIA A+ Core 2 220-1002 exam covers this topic in the following domains: 1.3 Explain the importance of security awareness and 2.2 Given a scenario, use secure data management and disaster recovery principles.

• Question 487:

  A technician is creating a tunnel that hides IP addresses and secures all network traffic. Which of the following protocols is capable of enduring enhanced security?

  A. DNS
  B. IPS
  C. VPN
  D. SSH
  C. VPN

  ---

  Explanation

  A VPN (virtual private network) is a protocol that creates a secure tunnel between two devices over the internet, hiding their IP addresses and encrypting their traffic.

  DNS (domain name system) is a protocol that translates domain names to IP addresses.

  IPS (intrusion prevention system) is a device that monitors and blocks malicious network traffic. SSH (secure shell) is a protocol that allows remote access and command execution on another device.

• Question 488:

  A technician is setting up backup and recovery solutions that must restore quickly. Storage space is not a factor. Which of the following backup methods should the technician implement?

  A. Differential
  B. Synthetic
  C. Full
  D. Incremental
  C. Full

  ---

  Explanation

  The correct answer is

  C. Full Backup.

  A Full Backup creates a complete copy of all selected data every time it runs. This method ensures the fastest possible recovery time because all the necessary data is contained in a single backup file. Since storage space is not a concern,

  full backups are ideal because they avoid the need to restore multiple incremental or differential backups. Recovery Time Objective (RTO) is minimized, making full backups the best choice for quick restoration.

  Why Other Options Are Incorrect:

  Option A: Differential Backup, Backs up only the data that has changed since the last full backup. While faster to restore than an incremental backup, it still requires both the last full backup and the most recent differential backup for

  restoration.

  Option B: Synthetic Backup, A synthetic full backup is created by combining previous full and incremental backups without needing to back up data again from the source. While efficient in terms of backup creation, restoration can be slower

  compared to a traditional full backup.

  Option D: Incremental Backup, Backs up only data that has changed since the last backup (whether full or incremental). While efficient in storage, restoring from incremental backups can be slow because multiple backups must be restored in

  sequence.

• Question 489:

  A technician is upgrading the backup system for documents at a high-volume law firm. The current backup system can retain no more than three versions of full backups before failing. The law firm is not concerned about restore times but asks the technician to retain more versions when possible. Which of the following backup methods should the technician MOST likely implement?

  A. Full
  B. Mirror
  C. Incremental
  D. Differential
  C. Incremental

  ---

  Explanation

  The law firm wants to retain more versions of the backups when possible, so the best backup method for the technician to implement in this scenario would be Incremental backup. Incremental backups only save the changes made since the last backup, which allows for more frequent backups and minimizes the amount of storage required. This would allow the law firm to retain more than three versions of backups without risking backup failure. To retain more versions of backups, the technician should implement an Incremental backup method12 An incremental backup method only backs up the data that has changed since the last backup, so it requires less storage space than a full backup12
