CompTIA SY0-701 Questions Answers

To reduce the number of individual operating systems while decommissioning physical servers, the company should use containerization. Containerization allows multiple applications to run in isolated environments on a single operating system, significantly reducing the overhead compared to running multiple virtual machines, each with its own OS.

Containerization: Uses containers to run multiple isolated applications on a single OS kernel, reducing the need for multiple OS instances and improving resource utilization.

Microservices: An architectural style that structures an application as a collection of loosely coupled services, which does not necessarily reduce the number of operating systems.

Virtualization: Allows multiple virtual machines to run on a single physical server, but each VM requires its own OS, not reducing the number of OS instances.

Infrastructure as code: Manages and provisions computing infrastructure through machine-readable configuration files, but it does not directly impact the number of operating systems.

 The correct answer is A because multifactor authentication (MFA) is a method of verifying a user’s identity by requiring more than one factor, such as something the user knows (e.g., password), something the user has (e.g., token), or something the user is (e.g., biometric). MFA can prevent unauthorized access even if the user’s password is compromised, as the attacker would need to provide another factor to log in. The other options are incorrect because they do not address the root cause of the attack, which is weak authentication. Permissions assignment (B) is the process of granting or denying access to resources based on the user’s role or identity. Access management © is the process of controlling who can access what and under what conditions. Password complexity (D) is the requirement of using strong passwords that are hard to guess or crack, but it does not prevent an attacker from using a stolen password. References = You can learn more about multifactor authentication and other security concepts in the following resources:

The first step in creating an anomaly detection process is building a baseline of normal behavior within the system. This baseline serves as a reference point to identify deviations or anomalies that could indicate a security incident. By understanding what normal activity looks like, security teams can more effectively detect and respond to suspicious behavior.

To demonstrate that the system can be restored to a working state in the event of a performance issue after deploying a change, the systems administrator must submit a backout plan. A backout plan outlines the steps to revert the system to its previous state if the new deployment causes problems.

Backout plan: Provides detailed steps to revert changes and restore the system to its previous state in case of issues, ensuring minimal disruption and quick recovery.

Impact analysis: Evaluates the potential effects of a change but does not provide steps to revert changes.

Test procedure: Details the steps for testing the change but does not address restoring the system to a previous state.

Approval procedure: Involves obtaining permissions for the change but does not ensure system recovery in case of issues.
