The SOA-C02 Exam focuses on a wide range of areas, including:
The AWS Certified SysOps Administrator - Associate (SOA-C02) and AWS Certified Developer - Associate (DVA-C02) exams are designed for different roles and focus on distinct areas of expertise within AWS. Here are the key differences:
A SysOps administrator wants to monitor the free disk space that is available on a set of Amazon EC2 instances that have Amazon Elastic Block Store (Amazon EBS) volumes attached. The SysOps administrator wants to receive a notification when the used disk space of the EBS volumes exceeds a threshold value, but only when the DiskReadOps metric also exceeds a threshold value The SysOps administrator has set up an Amazon Simple Notification Service (Amazon SNS) topic.
How can the SysOps administrator receive notification only when both metrics exceed their threshold values?
A SysOps administrator deployed a three-tier web application to a OA environment and is now evaluating the high availability of the application. The SysOps administrator notices that, when they simulate an unavailable Availability Zone, the application fails to respond. The application stores data in Amazon RDS and Amazon DynamoDB.
How should the SysOps administrator resolve this issue?
A SysOps administrator needs to configure a caching layer for a read-heavy application that uses an Amazon RDS for PostgreSQL database. The application exists across three AWS Regions. Read and write activities occur in the primary Region. In the two secondary Regions, read-only activity occurs on RDS for PostgreSQL cross-Region read replicas.
The cache in each Region must consist of the same data to provide a consistent user experience across Regions.
Which solution for the caching layer will meet these requirements?
