Accepted Answer

InvocationLatency. InvocationLatency and InvocationClientErrors are standard metrics provided for Bedrock in CloudWatch.

Answer

VectorEmbeddingAccuracy

Question 7

A healthcare company requires that all generative AI outputs be filtered for PII (Personally Identifiable Information) before being sent to the end user. Which Amazon Bedrock feature effectively manages this compliance requirement?

Accepted Answer

Amazon Bedrock Guardrails. Guardrails for Amazon Bedrock allows developers to configure PII filtering, profanity filters, and denial topics to ensure compliance.

Answer

AWS CloudTrail logs

Answer

AWS WAF on the API Gateway

Answer

IAM Policy evaluation for Bedrock

Question 8

A developer is preprocessing a large corpus of PDF documents for RAG. To ensure the highest accuracy for multi-modal retrieval tasks, which data strategy is most effective?

Accepted Answer

Applying semantic chunking and adding metadata tags for filtering. Chunking and metadata enrichment allow the retriever to locate specific sections rather than retrieving entire documents, improving precision.

Answer

Converting all text to images before embedding

Answer

Using a fixed-size character count of 500 without overlap

Answer

Concatenating all chunks into one large vector

Question 9

A company is integrating Amazon Bedrock with a private knowledge base. They need to ensure that PII is masked before the retrieved documents are passed to the Foundation Model. Which approach is most effective?

Accepted Answer

Implement an AWS Lambda function with Amazon Comprehend to redact PII during the ingestion process into the Knowledge Base.. Amazon Comprehend can be integrated into the data ingestion pipeline to detect and redact PII before documents are indexed into the Amazon OpenSearch Serverless vector store.

Answer

Configure the Bedrock Knowledge Base to use a custom encryption key for PII filtering.

Answer

Enable Amazon Macie on the S3 bucket and configure Bedrock to ignore flagged objects.

Answer

Use Amazon Bedrock Guardrails to mask PII during the inference request.

Question 10

A developer is troubleshooting a slow retrieval process in a RAG system. What is the most likely cause related to the vector store?

Accepted Answer

The vector index is missing an appropriate HNSW index or is not properly partitioned.. If the vector store lacks an index or the index is not partitioned correctly, search latency increases significantly.

Answer

The embedding model is too small.

Answer

The source documents are too short.

Answer

The Bedrock service is overloaded.

Question 11

A company is building a RAG application using Amazon Bedrock and needs to ensure that sensitive PII is filtered out before it reaches the foundation model. Which feature should be used to achieve this?

Accepted Answer

Amazon Bedrock Guardrails. Amazon Bedrock Guardrails allows users to configure content filters, including PII redaction, to prevent sensitive information from being processed by or returned from foundation models.

Answer

AWS WAF on the Bedrock API endpoint

Answer

Amazon Macie on the S3 bucket housing the source data

Answer

AWS Glue DataBrew

Question 12

Which THREE items must be configured when setting up a new Knowledge Base in Amazon Bedrock?

Accepted Answer

Embedding model selection.. Embedding model, data source, and vector database are the three mandatory components for a Knowledge Base.

Answer

Model evaluation dataset.

Answer

External firewall rules.

Question 13

You are deploying a foundation model on Amazon SageMaker. To optimize inference costs for an application with unpredictable traffic patterns and significant idle periods, which deployment option should you select?

Accepted Answer

SageMaker Serverless Inference. Serverless Inference is the most cost-effective solution for unpredictable traffic as it eliminates the cost of idle instances by automatically scaling resources based on request volume.

Answer

Batch Transform

Answer

Real-time inference with provisioned Auto Scaling instances

Answer

Asynchronous Inference

Question 14

Which TWO types of models are generally available in Amazon Bedrock?

Accepted Answer

Embedding models.. Text generation models and embedding models are the two most common types available in Bedrock.

Answer

Network load balancer configurations.

Answer

Hardware drivers.

Answer

OS kernel images.

Question 15

What is the primary function of the Bedrock 'Model Invocation Logs'?

Accepted Answer

To capture and store prompt/response payloads for auditing.. These logs are used for auditing and debugging by capturing the request and response payloads.

Answer

To throttle incoming requests.

Answer

To perform real-time model retraining.

Answer

To reduce inference costs.

Question 16

Which service should be used to manage user access to Amazon Bedrock models?

Accepted Answer

AWS IAM.. AWS IAM (Identity and Access Management) is the service used to control access to AWS resources, including Bedrock APIs.

Answer

Amazon Route 53.

Answer

Amazon SageMaker.

Answer

AWS Glue.

Question 17

A company is designing a RAG architecture. Which TWO of the following steps are required to successfully link an Amazon S3 source to an Amazon Bedrock Knowledge Base?

Accepted Answer

Configure an IAM role with S3 read access for Bedrock. The process requires selecting the data source (S3) and specifying the embedding model to convert text to vectors.

To act as a firewall for the RAG system.

Answer

To compress large files for storage.

Answer

To generate human-readable summaries.

Question 19

When should a developer choose to fine-tune a model versus using RAG?

Accepted Answer

When you need the model to learn a specific, consistent corporate tone.. RAG is best for grounding in changing data, while fine-tuning is better for changing the model's style, tone, or highly specialized domain language.

Answer

When you have very little data.

Answer

When you need to ensure the model does not hallucinate.

Answer

When the data changes daily.

Question 20
