Amazon AWS Certified Solutions Architect - Associate 認定 SAA-C03 試験問題 (Q71-Q76):

質問 # 71
A company wants to move a multi-tiered application from on premises to the AWS Cloud to improve the application's performance. The application consists of application tiers that communicate with each other by way of RESTful services. Transactions are dropped when one tier becomes overloaded. A solutions architect must design a solution that resolves these issues and modernizes the application.
Which solution meets these requirements and is the MOST operationally efficient?

正解：C

解説：
https://aws.amazon.com/getting-started/hands-on/build-serverless-web-app-lambda-apigateway-s3-dynamodb-cognito/module-4/ Build a Serverless Web Application with AWS Lambda, Amazon API Gateway, AWS Amplify, Amazon DynamoDB, and Amazon Cognito. This example showed similar setup as question: Build a Serverless Web Application with AWS Lambda, Amazon API Gateway, AWS Amplify, Amazon DynamoDB, and Amazon Cognito


質問 # 72
[Design Resilient Architectures]
A media company hosts its website on AWS. The website application's architecture includes a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB) and a database that is hosted on Amazon Aurora The company's cyber security teem reports that the application is vulnerable to SOL injection.
How should the company resolve this issue?

正解：B

解説：
https://aws.amazon.com/premiumsupport/knowledge-center/waf-block-common-attacks/#:~:text=To%20protect%20your%20applications%20against,%2C%20query%20string%2C%20or%20URI. ----------------------------------------------------------------------------------------------------------------------- Protect against SQL injection and cross-site scripting To protect your applications against SQL injection and cross-site scripting (XSS) attacks, use the built-in SQL injection and cross-site scripting engines. Remember that attacks can be performed ondifferent parts of the HTTP request, such as the HTTP header, query string, or URI. Configure the AWS WAF rules to inspect different parts of the HTTP request against the built-in mitigation engines.


質問 # 73
A company needs to use its on-premises LDAP directory service to authenticate its users to the AWS Management Console. The directory service is not compatible with Security Assertion Markup Language (SAML).
Which solution meets these requirements?

正解：B

解説：
The correct answer is D because the company needs to authenticate users from an on-premises LDAP directory to the AWS Management Console , but the directory is not SAML-compatible . In this scenario, the AWS-recommended pattern is to use a custom identity broker that authenticates users against the existing LDAP directory and then requests temporary AWS credentials from AWS Security Token Service (AWS STS) . This enables federated access to AWS without creating long-term IAM user credentials for each person.
A custom identity broker serves as the intermediary between the non-SAML directory and AWS. After validating a user with LDAP, the broker can call AWS STS to issue short-lived credentials or console sign-in access. This approach preserves the use of the company's existing identity source while meeting AWS security best practices for temporary credentials and centralized identity management.
Option A is incorrect because AWS IAM Identity Center typically relies on supported identity sources and federation methods, and the question explicitly states that the LDAP directory is not SAML-compatible.
Option B is incorrect because IAM policies do not integrate directly into LDAP as an authentication mechanism. Option C is incorrect because rotating IAM credentials tied to LDAP changes still relies on long- term credentials and does not provide a proper federated sign-in model.
AWS federation guidance supports the use of a custom identity broker when an organization has a non- SAML-compatible identity system. Therefore, the best solution is to develop an on-premises custom identity broker that uses AWS STS to obtain short-lived credentials for AWS Management Console access.


質問 # 74
A company needs to launch an Amazon EC2 instance with persistent block storage to host its application. The stored data must be encrypted at rest.
Which of the following is the most suitable storage solution in this scenario?

正解：D

解説：
Amazon Elastic Block Store (Amazon EBS) provides block-level storage volumes for use with EC2 instances. EBS volumes behave like raw, unformatted block devices. You can mount these volumes as devices on your instances. EBS volumes that are attached to an instance are exposed as storage volumes that persist independently from the life of the instance.

Amazon EBS is the persistent block storage volume among the options given. It is mainly used as the root volume to store the operating system of an EC2 instance. To encrypt an EBS volume at rest, you can use AWS KMS customer master keys for the encryption of both the boot and data volumes of an EC2 instance.
Hence, the correct answer is: Encrypted Amazon EBS volume using AWS KMS.
The options that say: Amazon EC2 Instance Store with SSL encryption and Encrypted Amazon EC2 Instance Store using AWS KMS are both incorrect because the scenario requires persistent block storage and not temporary storage. Also, enabling SSL is not a requirement in the scenario as it is primarily used to encrypt data in transit.
The option that says: Amazon EBS volume with server-side encryption (SSE) enabled is incorrect because EBS volumes are only encrypted using AWS KMS. Server-side encryption (SSE) is actually an option for Amazon S3, but not for Amazon EC2.

質問 # 75
A company is planning to build a high performance computing (HPC) workload as a service solution that Is hosted on AWS A group of 16 AmazonEC2Ltnux Instances requires the lowest possible latency for node-to-node communication. The instances also need a shared block device volume for high-performing storage.
Which solution will meet these requirements?

正解：D

解説：
Explanation
1. lowest possible latency + node to node ==> cluster placement(must be within one AZ), so C, D out
2. For EBS Multi-Attach, up to 16 instances can be attached to a single volume==>we have 16 linux instance==>more close to A
3. "need a shared block device volume"==>EBS Multi-attach is Block Storage whereas EFS is File Storage==> B out
4. EFS automatically replicates data within and across 3 AZ==>we use cluster placement so all EC2 are within one AZ.
5. EBS Multi-attach volumes can be used for clients within a single AZ.
