Amazon AWS Certified Solutions Architect - Professional (SAP-C02) 認定 SAP-C02 試験問題 (Q297-Q302):

質問 # 297
A software company has deployed an application that consumes a REST API by using Amazon API Gateway.
AWS Lambda functions, and an Amazon DynamoDB table. The application is showing an increase in the number of errors during PUT requests. Most of the PUT calls come from a small number of clients that are authenticated with specific API keys.
A solutions architect has identified that a large number of the PUT requests originate from one client. The API is noncritical, and clients can tolerate retries of unsuccessful calls. However, the errors are displayed to customers and are causing damage to the API's reputation.
What should the solutions architect recommend to improve the customer experience?

正解：C

解説：
https://aws.amazon.com/premiumsupport/knowledge-center/aws-batch-requests-error/
https://aws.amazon.com/premiumsupport/knowledge-center/api-gateway-429-limit/ The main problem is that one client is generating a large number of PUT requests, resulting in increased errors. Because the clients are authenticated by API keys and the problematic traffic is concentrated among a small set of clients, API Gateway usage plans and throttling are a direct control mechanism to limit the request rate per client (or per API key). The API is noncritical and clients can tolerate retries, so returning throttling responses is acceptable as long as clients handle them correctly. The goal is to reduce visible customer-facing errors and protect the API from being overwhelmed by a single client.
API Gateway usage plans can set request throttling limits (rate and burst) per API key. When a client exceeds the configured throttle, API Gateway returns HTTP 429 (Too Many Requests). If the client application is designed to treat 429 as a normal, retryable condition rather than a fatal error, the user experience improves because the client can back off and retry instead of surfacing raw failures. This approach prevents one noisy client from degrading service for other users and reduces the overall error rate.
Option B addresses the root cause (excess requests from a particular client) by enforcing throttling at the API Gateway layer and improving client behavior when throttled.
Option A focuses on client-side retries and error handling but does not enforce fairness or prevent a single client from consuming disproportionate API capacity. Without throttling, the same client can continue to overload downstream Lambda and DynamoDB capacity and still cause errors for everyone.
Option C (API caching) does not help for PUT requests because PUT operations are writes and are generally not cacheable in a way that reduces write load. Caching is mainly beneficial for GET responses and read- heavy workloads.
Option D (reserved concurrency) can protect Lambda capacity for critical functions, but it can also cause throttling at the Lambda layer and does not directly address controlling the request rate per API key. It also does not fix the issue at the API front door where the noisy client should be managed.
Therefore, implementing API Gateway throttling via a usage plan and ensuring clients handle 429 responses properly is the best recommendation.

質問 # 298
A company is planning a large event where a promotional offer will be introduced. The company's website is hosted on AWS and backed by an Amazon RDS for PostgreSQL DB instance. The website explains the promotion and includes a sign-up page that collects user information and preferences Management expects large and unpredictable volumes of traffic periodically which will create many database writes A solutions architect needs to build a solution that does not change the underlying data model and ensures that submissions are not dropped before they are committed to the database
Which solutions meets these requirements'?

正解：A


質問 # 299
A solutions architect is designing a multi-account structure that has 10 existing accounts. The design must meet the following requirements
* Consolidate all accounts into one organization
* Allow full access to the Amazon EC2 service from the management account and the secondary accounts
* Minimize the effort required to add additional secondary accounts
Which combination of steps should be included in the solution? (Select TWO )

正解：A、C


質問 # 300
A company with several AWS accounts is using AWS Organizations and service control policies (SCPs). An Administrator created the following SCP and has attached it to an organizational unit (OU) that contains AWS account 1111-1111-1111:

Developers working in account 1111-1111-1111 complain that they cannot create Amazon S3 buckets. How should the Administrator address this problem?

正解：C

解説：
However A's explanation is incorrect -https://docs.aws.amazon.com/organizations/latest/userguide
/orgs_manage_policies_scps.html
"SCPs are similar to AWS Identity and Access Management (IAM) permission policies and use almost the same syntax. However, an SCP never grants permissions." SCPs alone are not sufficient to granting permissions to the accounts in your organization. No permissions are granted by an SCP. An SCP defines a guardrail, or sets limits, on the actions that the account's administrator can delegate to the IAM users and roles in the affected accounts. The administrator must still attach identity- based or resource-based policies to IAM users or roles, or to the resources in your accounts to actually grant permissions. The effective permissions are the logical intersection between what is allowed by the SCP and what is allowed by the IAM and resource-based policies.


質問 # 301
A company needs to architect a hybrid DNS solution. This solution will use an Amazon Route 53 private hosted zone for the domain cloud.example.com for the resources stored within VPCs.
The company has the following DNS resolution requirements:
* On-premises systems should be able to resolve and connect to cloud.example.com.
* All VPCs should be able to resolve cloud.example.com.
There is already an AWS Direct Connect connection between the on-premises corporate network and AWS Transit Gateway. Which architecture should the company use to meet these requirements with the HIGHEST performance?

正解：C

解説：
Explanation
Amazon Route 53 Resolver is a managed DNS resolver service from Route 53 that helps to create conditional forwarding rules to redirect query traffic1. By associating the private hosted zone to all the VPCs, the solutions architect can enable DNS resolution for cloud.example.com within the VPCs. By creating a Route 53 inbound resolver in the shared services VPC, the solutions architect can enable DNS resolution for cloud.example.com from on-premises systems. By attaching all VPCs to the transit gateway, the solutions architect can enable connectivity between the VPCs and the on-premises network through AWS Direct Connect. By creating forwarding rules in the on-premises DNS server for cloud.example.com that point to the inbound resolver, the solutions architect can direct DNS queries for cloud.example.com to the Route 53 Resolver endpoint in AWS.
This solution will provide the highest performance as it leverages Route 53 Resolver's optimized routing and caching capabilities.
