20+ practice questions focused on Technology — one of the most tested topics on the AWS Certified SAP on AWS Specialty PAS-C01 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Technology PracticeA company is running a web application on EC2 instances behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group with a dynamic scaling policy based on average CPU utilization. During a flash sale, the application experiences a sudden spike in traffic, but the Auto Scaling group does not scale out quickly enough, causing some requests to fail. Which solution would improve the scaling responsiveness?
Explanation: Option B is correct because a scheduled scaling action proactively increases capacity before the flash sale, eliminating the lag inherent in dynamic scaling policies. Dynamic scaling reacts to metrics like average CPU utilization, which can take minutes to trigger and propagate, causing request failures during sudden spikes. By pre-scaling, the Auto Scaling group has sufficient instances ready to handle the traffic surge immediately.
A company is migrating a legacy application to AWS. The application uses a custom TCP protocol and requires session persistence. The application runs on a fleet of EC2 instances behind a Network Load Balancer (NLB). The current configuration uses a TCP listener with 'source IP' stickiness. However, some clients are being routed to different instances mid-session, causing application errors. What is the most likely cause and solution?
Explanation: Option B is correct because clients behind a NAT gateway will have their source IP address translated to the NAT gateway's public IP, which remains consistent for all requests from that gateway. However, if multiple clients share the same NAT gateway, the source IP is the same, but the NLB's source IP stickiness is based on the client's source IP as seen by the NLB. If the NAT gateway uses multiple public IPs or if clients are behind different NAT gateways, the source IP can change between requests, breaking stickiness. The solution is to use a 'stitched' cookie or switch to an Application Load Balancer, which supports cookie-based session persistence independent of source IP.
A solutions architect is designing a disaster recovery plan for a critical application that runs on Amazon RDS for PostgreSQL. The application requires a Recovery Point Objective (RPO) of less than 5 seconds and a Recovery Time Objective (RTO) of less than 1 minute. Which RDS deployment option meets these requirements?
Explanation: Amazon RDS Multi-AZ deployments with synchronous replication provide automatic failover to a standby instance in a different Availability Zone, ensuring data is committed to both primary and standby before acknowledging a write. This achieves an RPO of effectively zero (less than 5 seconds) and an RTO typically under 1 minute, meeting the stated requirements.
A company is using AWS CloudFormation to manage infrastructure. The development team wants to deploy a new version of a stack that updates an existing RDS DB instance's DB engine version. The update requires a replacement of the database. Which CloudFormation stack policy setting allows the update to proceed while preventing other resources from being replaced or updated?
Explanation: Option B is correct because a stack policy in AWS CloudFormation can be set to explicitly allow updates to a specific resource (e.g., the RDS DB instance) while denying updates to all other resources by default. Since the update requires a replacement of the database, the policy must permit the update action on that exact resource logical ID, ensuring the DB engine version change proceeds without risking unintended modifications to other stack resources.
A company is running a stateful application on EC2 instances in an Auto Scaling group. The instances store session state locally. The group uses a simple scaling policy based on network traffic. The company notices that when instances are terminated during scale-in, active sessions are lost. What is the MOST effective way to preserve session state during scaling events?
Explanation: A lifecycle hook is the most effective solution because it pauses the instance termination process during scale-in, allowing the application to drain active sessions (e.g., by transferring session state to a shared data store like ElastiCache or DynamoDB) before the instance is fully terminated. This preserves session continuity without requiring architectural changes to the application's stateful design.

Practice all Technology questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Technology. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Technology questions on the PAS-C01 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Technology is tested as part of the AWS Certified SAP on AWS Specialty PAS-C01 blueprint. Practicing with targeted Technology questions ensures you can handle any format or difficulty that appears.
