Amazon AWS Certified Solutions Architect - Associate (SAA-C02) Exam 認定 SAA-C02 試験問題 (Q373-Q378):
質問 # 373
A restaurant reservation application needs to access a waiting list. When a customer tries to reserve a table, and none are available, the customer application will put the user on the waiting list, and the application will notify the customer when a table becomes free. The waiting list must preserve the order in which customers were added to the waiting list.
Which service should the solutions architect recommend to store this waiting list?
- A. A FIFO queue in Amazon Simple Queue Service (Amazon SQS)
- B. Amazon Simple Notification Service (Amazon SNS)
- C. A standard queue in Amazon Simple Queue Service (Amazon SQS)
- D. AWS Step Functions invoking AWS Lambda functions

質問 # 374
A company's website is using an Amazon RDS MySQL Multi-AZ DB instance for its transactional data storage.
There are other internal systems that query this DB instance to fetch data for internal batch processing. The RDS DB instance slows down significantly the internal systems fetch data. This impacts the website's read and write performance, and the users experience slow response times.
Which solution will improve the website's performance?
- A. Use an RDS PostgreSQL DB instance instead of a MySQL database.
- B. Add a read replica to the RDS DB instance and configure the internal systems to query the read replica.
- C. Add an additional Availability Zone to the current RDS MySQL Multi.AZ DB instance.
- D. Use Amazon ElastiCache to cache the query responses for the website.
正解：B
解説：
Amazon RDS Read Replicas
Enhanced performance
You can reduce the load on your source DB instance by routing read queries from your applications to the read replica. Read replicas allow you to elastically scale out beyond the capacity constraints of a single DB instance for read-heavy database workloads. Because read replicas can be promoted to master status, they are useful as part of a sharding implementation.
To further maximize read performance, Amazon RDS for MySQL allows you to add table indexes directly to Read Replicas, without those indexes being present on the master.

質問 # 375
A company is investigating potential solutions that would collect, process, and store users' service usage data. The business objective is to create an analytics capability that will enable the company to gather operational insights quickly using standard SQL queries. The solution should be highly available and ensure Atomicity, Consistency, Isolation, and Durability (ACID) compliance in the data tier.
Which solution should a solutions architect recommend?
- A. Use a fully managed Amazon RDS for MySQL database in a Multi-AZ design
- B. Use Amazon DynamoDB transactions
- C. Create an Amazon Neptune database in a Multi AZ design
- D. Deploy PostgreSQL on an Amazon EC2 instance that uses Amazon EBS Throughput Optimized HDD (st1) storage.

正解：C、E
解説：
Explanation
AWS Global Accelerator
Acceleration for latency-sensitive applications
Many applications, especially in areas such as gaming, media, mobile apps, and financials, require very low latency for a great user experience. To improve the user experience, Global Accelerator directs user traffic to the application endpoint that is nearest to the client, which reduces internet latency and jitter. Global Accelerator routes traffic to the closest edge location by using Anycast, and then routes it to the closest regional endpoint over the AWS global network. Global Accelerator quickly reacts to changes in network performance to improve your users' application performance.
Amazon CloudFront
Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency, high transfer speeds, all within a developer-friendly environment.
