Security in Amazon Web Services (CISN 74A) Practice Test 2025 – Complete Guide to Master AWS Security!

AWS Shield is a managed security service designed specifically to protect applications running on the AWS cloud from Distributed Denial of Service (DDoS) attacks. It continuously monitors traffic to detect and mitigate potential DDoS threats before they can impact applications and services. The service uses sophisticated algorithms and extensive network capacity to absorb and mitigate attacks, helping to ensure that legitimate traffic can reach your applications without significant interruption.

The focus of AWS Shield on DDoS protection makes it particularly valuable for maintaining the availability and resilience of applications, especially those that are critical for business operations or customer interactions. By providing this layer of security, AWS Shield helps organizations minimize the risk and impact of DDoS attacks, which can cause severe downtime and service disruptions.

In contrast, the other options involve unrelated functionalities, such as data backup, application migration, or physical security measures in AWS data centers, none of which pertain to the primary purpose of AWS Shield. Thus, the emphasis on DDoS protection underscores the significance of AWS Shield in comprehensive cloud security strategies.
