Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q149-Q154):

NEW QUESTION # 149
A company hosts an online order-processing application on Amazon EC2 instances. The instances are part of an EC2 Auto Scaling group that spans multiple Availability Zones and uses a scheduled scaling policy. The application uses Amazon RDS for MySQL as its database.
Although the database is write-heavy, Amazon CloudWatch metrics do not show any problems during peak usage periods. However, application users randomly experience slow responses when creating new orders.
Which solution will improve the application's response time without changing the application design or infrastructure?

Answer: C

Explanation:
A scheduled scaling policy is appropriate only when workload changes occur at known and predictable times.
The random slow responses indicate that application-tier demand does not consistently match the predefined schedule. A target tracking policy continuously monitors a metric such as average CPU utilization or Application Load Balancer request count and automatically adjusts the Auto Scaling group's desired capacity to maintain the configured target. This allows the EC2 tier to respond to unexpected traffic increases without redesigning the application. Dedicated Hosts and placement groups do not provide elastic capacity for unpredictable demand. Migrating to DynamoDB would substantially change the application architecture.
ElastiCache would introduce new infrastructure and is primarily effective for cacheable read traffic, whereas the reported operation creates new orders and is write-oriented. Target tracking is therefore the least disruptive solution.


NEW QUESTION # 150
A company runs a production application on a fleet of Amazon EC2 instances. The application reads the data from an Amazon SQS queue and processes the messages in parallel. The message volume is unpredictable and often has intermittent traffic. This application should continually process messages without any downtime.
Which solution meets these requirements MOST cost-effectively?

Answer: A

Explanation:
We recommend that you use On-Demand Instances for applications with short-term, irregular workloads that cannot be interrupted.

NEW QUESTION # 151
An IAM user made several configuration changes to AWS resources m their company's account during a production deployment last week. A solutions architect learned that a couple of security group rules are not configured as desired. The solutions architect wants to confirm which IAM user was responsible for making changes.
Which service should the solutions architect use to find the desired information?

Answer: D


NEW QUESTION # 152
A solutions architect needs to save a particular automated database snapshot from an Amazon RDS for Microsoft SQL Server DB instance for longer than the maximum number of days. Which solution will meet these requirements in the MOST operationally efficient way?

Answer: A

Explanation:
Creating a manual copy of the automated snapshot is the most operationally efficient option because it directly meets the requirement--retain a specific snapshot beyond the automated retention window--with the least added process and tooling. In Amazon RDS, automated backups and their snapshots are retained only for the configured backup retention period (up to the service maximum).
When that retention period is exceeded, older automated snapshots are removed automatically.
However, manual snapshots are retained until you explicitly delete them, so converting (copying) an automated snapshot to a manual snapshot is the standard operational approach to keep a point-in-time backup for long-term retention.


NEW QUESTION # 153
A company is designing a website that displays stock market prices to users. The company wants to use Amazon ElastiCache (Redis OSS) for the data caching layer. The company needs to ensure that the website's data caching layer can automatically fail over to another node if necessary.

Answer: A

Explanation:
For high availability, Amazon ElastiCache for Redis supports Multi-AZ with automatic failover, which provides primary and replica nodes in different Availability Zones. If the primary node fails, Redis automatically promotes a replica to primary.
From AWS Documentation:
"When you enable Multi-AZ with automatic failover, Amazon ElastiCache automatically detects failures and promotes a read replica to primary with minimal downtime." (Source: Amazon ElastiCache for Redis User Guide) Why B is correct:
* Multi-AZ provides automatic failover and data replication.
* Ensures continuous availability and protects against node or AZ failures.
* Fully managed with no manual intervention needed.
Why others are incorrect:
* A: Manual promotion is not automatic.
* C & D: Restoring from backup is slow and meant for disaster recovery, not failover.
