Geographic dispersion is the practice of having backup data stored in different locations that are far enough apart to minimize the risk of a single natural disaster affecting both sites. This ensures that the company can recover its regulated data in case of a disaster at the primary site. Platform diversity, hot site, and load balancing are not directly related to the protection of backup data from natural disasters. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 449; Disaster Recovery Planning: Geographic Diversity

Encryption is a reversible process that transforms cleartext data into ciphertext to protect confidentiality. It uses cryptographic keys to both encrypt and decrypt data, ensuring that only authorized parties can access the original data.

Hashing, on the other hand, is a one-way function that converts data into a fixed-length hash value or checksum. Hashing is primarily used to verify data integrity by detecting changes, since any modification in the input will produce a different hash output. Unlike encryption, hashing cannot be reversed to obtain the original data.

While encryption can protect data both at rest and in transit, hashing does not protect data confidentiality but supports integrity verification. Public-key exchange is a cryptographic mechanism within asymmetric encryption but is unrelated to hashing key usage.

This distinction is thoroughly explained in the Cryptography chapter of the SY0-701 syllabus【6:Chapter 7†CompTIA Security+ Study Guide】.

An image backup, also known as a full system backup, captures the entire contents of a system, including the operating system, applications, settings, and all data. This type of backup allows for a complete recovery of the system in case of a disaster, as it includes everything needed to restore the system to its previous state. This makes it the ideal choice for a systems administrator who needs to ensure the ability to recover the entire system, including the OS.

Comprehensive and Detailed In-Depth Explanation:

Mobile Device Management (MDM) is a security solution that allows organizations to enforce policies on employee-owned or company-issued mobile devices. It can restrict the installation of unauthorized applications, ensuring that only company-approved apps are used.

Containerizationisolates work applications from personal applications but does not enforce app restrictions.

Data Loss Prevention (DLP)focuses on preventing sensitive data leaks rather than managing app installations.

File Integrity Monitoring (FIM)tracks changes to files and system configurations but does not control app installations.

Therefore,MDMis the best solution for restricting unauthorized applications on personal devices.
