Which Security Requirement Does a Load Balancer Fulfill?

SY0-701 By islever Editorial Last updated

Short answer

D Availability

Question

A network administrator is working on a project to deploy a load balancer in the company's cloud environment. Which of the following fundamental security requirements does this project fulfil?
  1. Privacy
  2. Integrity
  3. Confidentiality
  4. Availability Correct Answer

Key Takeaways

The question tests your ability to map cloud infrastructure components to the CIA triad; the trap is confusing load balancer benefits with confidentiality or integrity.

Deploying a load balancer in a cloud environment primarily fulfills the availability security requirement by distributing traffic and ensuring continuous access to resources. The CompTIA Security+ community consensus is that availability is the correct answer.

Common mistake: Choosing confidentiality or integrity because load balancers often handle TLS termination or secure traffic, but the fundamental security requirement of load balancing is availability—keeping systems online and accessible.

Expert Analysis

Why the Answer Is Correct

Availability ensures that systems and data are accessible when needed by authorized users. A load balancer distributes incoming traffic across multiple servers, preventing any single server from becoming a single point of failure. As one commenter noted, it provides redundancy and ensures continued access even in the event of server failures, directly supporting availability.

Why the Other Options Are Wrong

Privacy (option A) is not one of the core CIA triad requirements, though it relates to data protection. Confidentiality (option C) protects data from unauthorized access, but load balancing is not primarily designed for access control. Integrity (option B) ensures data is not modified, but load balancers do not validate or ensure data integrity by themselves. Availability is the only option that directly matches the purpose of a load balancer.

Community Comment Notes

Comment [1] points out that load balancing enhances availability by distributing traffic and providing redundancy, even during server failures. Comment [2] explains that load balancing optimizes execution time, response time, and system stability, which improves cloud performance and therefore availability. Both comments reinforce that the security requirement fulfilled by this project is availability.

Exam Strategy

When asked which security requirement a specific technology fulfills, map the technology's primary function to the CIA triad. For load balancers, focus on keeping services accessible despite failures—that is availability. Memorize common examples: backups and redundancy support availability; encryption supports confidentiality; hashing and checksums support integrity.

    Availability is the correct answer because deploying a load balancer enhances the availability of applications and services by distributing traffic, providing redundancy, and ensuring continued access to resources even in the event of server failures. This project directly supports the availability aspect of the security triad.

    D. Availability Load balancing in cloud computing distributes traffic and workloads to ensure that no single server or machine is under-loaded, overloaded, or idle. Load balancing optimizes various constrained parameters such as execution time, response time, and system stability to improve overall cloud performance. Therefore it allows the systems more availability.
