Udemy has a limit of 6 practice tests per course so I had to cram 200 questions into each practice test for your exam preparation.Every question has a detailed explanation of why an option is correct and why the other options are wrong. Here is an example:Q. Which AWS Service when used in combination with AWS Shield provides you comprehensive availability protection against all known infrastructure (Layer 3 and 4) attacks?A. WAF.B. Elastic Load Balancer.C. CloudTrail.D. CloudFront.WAF. is not correct.AWS WAF is a web application firewall that helps protect your web applications or APIs against common web exploits that may affect availability, compromise security, or consume excessive resources. AWS WAF gives you control over how traffic reaches your applications by enabling you to create security rules that block common attack patterns, such as SQL injection or cross-site scripting, and rules that filter out specific traffic patterns you define.Ref: Elastic Load Balancer. is not correct.Elastic Load Balancing automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, Lambda functions, and virtual appliances. It can handle the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones.Ref: Cloud Trail. is not correct.Cloud Trail is pefect for this requirement. Unusual activity detection use case: You can detect unusual activity in your AWS accounts by enabling CloudTrail Insights. For example, you can quickly alert and act on operational issues such as erroneous spikes in resource provisioning or services hitting rate limits.Ref: CloudFront. is correct.When using Amazon CloudFront, AWS Shield Standard automatically provides comprehensive protection against infrastructure layer attacks like SYN floods, UDP floods, or other Reflection attacks. AWS Shield Standard's always-on detection and mitigation systems automatically scrubs bad traffic at Layer 3 and 4 to protect your application. Over 99% of infrastructure layer attacks detected by AWS Shield Standard are automatically mitigated in less than 1 second for attacks on Amazon CloudFront.Ref: See you on the inside (hurry, your practice tests are waiting!)
