The other options, such as storing structured data in a relational database, deploying containerized applications, or analyzing real-time data streams, are not the primary use cases for OpenSearch Service. While it can be used in conjunction with other services for these purposes, its core functionality revolves around search and analytics capabilities.

Question 2

Which of the following data formats is not supported by Amazon OpenSearch Service for data ingestion?

Correct Answer: XML

Amazon OpenSearch Service supports ingesting data in JSON, CSV, and plain text log formats. However, it does not natively support ingesting data in XML format. To ingest XML data into OpenSearch, you would need to preprocess and convert the XML data into a supported format such as JSON before ingesting it.

Question 3

What is the primary purpose of Amazon OpenSearch Service?

Correct Answer: To provide a managed service for deploying, operating, and scaling OpenSearch clusters in the AWS Cloud

The primary purpose of Amazon OpenSearch Service is to provide a managed service for deploying, operating, and scaling OpenSearch clusters in the AWS Cloud. OpenSearch is a popular open-source search and analytics engine. By using Amazon OpenSearch Service, users can easily set up, manage, and scale OpenSearch clusters without having to worry about the underlying infrastructure. The other options are incorrect because they describe different managed services offered by AWS: - Amazon DocumentDB is a fully managed document database service that supports MongoDB workloads. - Amazon Keyspaces is a managed service for running and scaling Apache Cassandra workloads in the AWS Cloud. - Amazon Neptune is a managed graph database service for building and running applications with highly connected datasets.
