Comprehensive and Detailed In-Depth Explanation:

Aload balancerdistributes incoming traffic evenly across multiple servers to prevent any single server from becoming overloaded. This ensureshigh availability, scalability, and optimal performanceof the company's website.

Server multiprocessing (A)refers to the use of multiple processors within a single server but does not distribute traffic across multiple servers.

A warm site (B)is a disaster recovery strategy, not a method for balancing real-time traffic.

A proxy server (D)acts as an intermediary between users and web services but does not distribute server load.

Using aload balancerallows forefficient traffic management and prevents server overload.

Peer review and approval is a practice that involves having other developers or experts review the code before it is deployed or released. Peer review and approval can help detect and prevent malicious code, errors, bugs, vulnerabilities, and poor quality in the development process. Peer review and approval can also enforce coding standards, best practices, and compliance requirements. Peer review and approval can be done manually or with the help of tools, such as code analysis, code review, and code signing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 11: Secure Application Development, page 543 2

Anair-gapped (C)system is completely isolated from unsecured networks (like the internet) and other systems, preventing any form of remote access. This is often used in highly sensitive environments such as military, nuclear, or critical infrastructure systems.

This is mentioned underDomain 3.4: Given a scenario, apply cybersecurity resilience conceptsin theCompTIA Security+ SY0-701 Exam Objectives, specifically under“Isolation (e.g., air-gapped)”.

Encryption is a method of transforming data in a way that makes it unreadable without a secret key necessary to decrypt the data back into plaintext. Encryption is one of the most common and effective ways to protect data at rest, as it prevents unauthorized access, modification, or theft of the data. Encryption can be applied to different types of data at rest, such as block storage, object storage, databases, archives, and so on. Hashing, tokenization, and segmentation are not methods of rendering data at rest unreadable, but rather of protecting data in other ways. Hashing is a one-way function that generates a fixed-length output, called a hash or digest, from an input, such that the input cannot be recovered from the output. Hashing is used to verify the integrity and authenticity of data, but not to encrypt it. Tokenization is a process that replaces sensitive data with non-sensitive substitutes, called tokens, that have no meaning or value on their own. Tokenization is used to reduce the exposure and compliance scope of sensitive data, but not to encrypt it. Segmentation is a technique that divides a network or a system into smaller, isolated units, called segments, that have different levels of access and security. Segmentation is used to limit the attack surface and contain the impact of a breach, but not to encrypt data at rest. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, pages 77-781; Protecting data at rest - Security Pillar3
