Ensuring that other team members understand how a script works is essential to prevent a single point of failure. If only one person knows how the script operates, the organization risks being unable to maintain or troubleshoot it if that person is unavailable. Sharing knowledge ensures continuity and reduces dependence on one individual.
* Reducing implementation cost and remediating technical debt are secondary considerations in this context.
* Identifying complexity is important, but the main benefit is to avoid a single point of failure.

Detailed Explanation:Quarantining a potentially infected system by placing it into an air-gapped environment physically disconnects it from the network. This prevents the spread of malware while maintaining the integrity of forensic evidence.

Serverless architecture allows companies to deploy code without managing the underlying infrastructure. This approach significantly reduces the time and expense involved in code deployment because developers can focus solely on writing code, while the cloud provider manages the servers, scaling, and maintenance.
Serverless computing also enables automatic scaling and pay-per-execution billing, which further optimizes costs.

CompTIA Security+ SY0-701 Course Content: The course covers cloud technologies, including serverless architectures, which are highlighted as a method to streamline and reduce costs associated with code deployment.

Software-defined networking (SDN) enables microsegmentation by allowing administrators to create fine- grained, dynamic network segments at the software layer independent of physical network topology. This capability isolates workloads and controls traffic flows between segments, enhancing security within data centers and cloud environments.
Next-generation firewalls (A) provide advanced filtering and inspection but do not inherently deliver the granular segmentation flexibility of SDN. Embedded systems (C) and air-gapped systems (D) refer to specific hardware or physical isolation techniques but do not implement microsegmentation as a network control method.
The concept of microsegmentation through SDN is detailed in the Security Architecture domain of the SY0-
701 exam#6:Chapter 3†CompTIA Security+ Study Guide#.
