SAA-C03 Design High-Performing Architectures Practice Question
A media archive needs low-latency full-text search across product descriptions and filtered attributes. Which managed service is most suitable? The design must avoid adding custom operational scripts.
⚠ Common exam trap
The trap here is that candidates might confuse AWS Config's resource tracking or EFS's file storage with search capabilities, overlooking that OpenSearch Service is the only managed option purpose-built for full-text search and filtering.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon OpenSearch Service
Amazon OpenSearch Service is the correct choice because it provides managed, low-latency full-text search capabilities with support for filtering on structured attributes (e.g., product categories, price ranges). It indexes JSON documents and exposes a RESTful API for search queries, eliminating the need for custom operational scripts while meeting the media archive's requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Config
Why it's wrong here
AWS Config records and evaluates resource configuration compliance; it holds no searchable document index and cannot serve full-text queries. It is tempting as a managed AWS service, but it suits configuration drift auditing, not product-description search.
- ✓
Amazon OpenSearch Service
Why this is correct
Amazon OpenSearch Service provides managed full-text search with low-latency querying across document fields, plus filter clauses for structured attributes. It satisfies the no-custom-operational-scripts constraint because AWS handles cluster provisioning, patching and scaling, unlike self-managed search engines requiring bespoke maintenance automation.
- ✗
Amazon EFS
Why it's wrong here
Amazon EFS provides shared file storage mountable by compute instances; it offers no indexing or query API, so full-text search would require custom scripts, breaching the constraint. EFS fits shared file access across instances, not managed search.
- ✗
Amazon SQS
Why it's wrong here
SQS queues messages and does not provide search indexing.
