.pkg and .dmg are files used to distribute and install applications on macOS. .pkg files are installer packages that may contain multiple files and executable code, while .dmg files are disk images that can contain a single bundled application or multiple applications. .app files are typically the main executable files for macOS applications. The other options listed are file extensions for applications or installers on other platforms (such as .deb for Debian- based Linux systems, .msi for Windows, and .apk for Android). This information is covered in the Comptia A+ Core2 documents/guide under the Mac OS section.
A technician downloads a validated security tool and notes the vendor hash of a58e87a2. When the download is complete, the technician again validates the hash, but the value returns as 2a876a7d3. Which of the following is the MOST likely cause of the issue?
Correct Answer:
C
The most likely cause of the issue of having different hash values for a downloaded security tool is a modified file. A hash value is a unique and fixed-length string that isgenerated from an algorithm that processes data or files. A hash value can be used to verify the integrity and authenticity of data or files by comparing it with a known or expected value. If the hash values do not match, it means that the data or file has been altered or corrupted in some way. A modified file may result from intentional or unintentional changes, such as editing, encryption, compression or malware infection. Private-browsing mode is a feature that allows users to browse the web without storing any browsing history, cookies or cache on their browser. Private-browsing mode does not affect the hash value of a downloaded file but only how the browser handles user data. Invalid certificate is an error that occurs when a website or a server does not have a valid or trusted digital certificate that proves its identity and secures its communication. Invalid certificate does not affect the hash value of a downloaded file but only how the browser verifies the website or server’s credibility. Browser cache is a temporary storage that stores copies of web pages, images and other content that users have visited on their browser.
A user is setting up backups on a workstation. The user wants to ensure that the restore process is as simple as possible. Which of the following backup types should the user select?
Correct Answer:
A
Full backup is the best option to ensure that the restore process is as simple as possible. A full backup is a backup type that copies all the data from the source to the destination, regardless of whether the data has changed or not. A full backup provides the most complete and consistent backup of the data, and it allows the user to restore the data from a single backup set without relying on any previous or subsequent backups. Incremental, differential, and synthetic backups are not as simple as full backups for restoring data. An incremental backup is a backup type that copies only the data that has changed since the last backup, whether it was full or incremental. An incremental backup requires less time and space than a full backup, but it also requires multiple backup sets to restore the data completely. A differential backup is a backup type that copies only the data that has changed since the last full backup. A differential backup requires more time and space than an incremental backup, but it also requires fewer backup sets to restore the data than an incremental backup. A synthetic backup is a backup type that combines a full backup with one or more incremental or differential backups to create a consolidated backup set. A synthetic backup requires less time and bandwidth than a full backup, but it also requires more processing power and storage space than an incremental or differential backup. References:
