AWS SAP-C02: Design for New Solutions Practice Questions

5 free sample questions from the Design for New Solutions domain, with answers and explanations. The full SAP-C02 bank has 59 questions across 4 domains. Questions are scenario-based and written from the official AWS exam guide.

1.

A new global application requires low-latency, static-anycast entry points and fast failover across Regions for a TCP/UDP workload (not just HTTP). Which service should the architect recommend?

  • A. AWS Global Accelerator✓ Correct
  • B. Amazon CloudFront only
  • C. A single regional Application Load Balancer
  • D. Amazon Route 53 with no health checks
Explanation

AWS Global Accelerator provides static anycast IPs and routes traffic over the AWS backbone to the optimal healthy endpoint across Regions, with fast failover, for TCP/UDP workloads. CloudFront (B) targets HTTP content caching, a single regional ALB (C) isn't global, and Route 53 without health checks (D) can't fail over intelligently.

2.

A new solution needs a highly available, serverless, key-value database that scales automatically to millions of requests per second with single-digit-millisecond latency. Which service should the architect recommend?

  • A. Amazon DynamoDB✓ Correct
  • B. Amazon RDS single instance
  • C. A self-managed database on one EC2 instance
  • D. Amazon Redshift
Explanation

DynamoDB is a serverless, highly available NoSQL key-value store that scales to very high request rates with low latency. A single RDS instance (B) or single EC2 database (C) can't match that elastic scale/availability, and Redshift (D) is a data warehouse for analytics, not low-latency key-value serving.

3.

A cost-sensitive new batch workload can tolerate interruptions and restarts. Which EC2 purchasing option minimizes cost for this fault-tolerant work?

  • A. Spot Instances✓ Correct
  • B. Dedicated Hosts
  • C. Reserved Instances with no flexibility
  • D. On-Demand Instances running 24/7
Explanation

Spot Instances offer the deepest discount for interruption-tolerant, restartable workloads like fault-tolerant batch jobs. On-Demand (D) is the most expensive steady option, Dedicated Hosts (B) are for licensing/compliance at premium cost, and Reserved Instances (C) suit steady 24/7 usage, not interruptible batch.

4.

For a globally used web app, static and dynamic content must be delivered with low latency worldwide and protected by a web application firewall. Which combination should the architect recommend?

  • A. Amazon CloudFront (CDN) with AWS WAF attached✓ Correct
  • B. A single EC2 instance in one Region
  • C. Amazon S3 static hosting with no distribution
  • D. AWS Direct Connect for end users
Explanation

CloudFront caches and accelerates content from edge locations worldwide, and AWS WAF attached to it filters malicious requests. A single-Region instance (B) can't deliver low global latency, plain S3 hosting (C) lacks global edge acceleration and WAF, and Direct Connect (D) is for private corporate connectivity, not public end users.

5.

A new relational database must survive an AZ failure automatically with minimal data loss, without the team managing replication. Which option should the architect recommend?

  • A. Amazon RDS Multi-AZ deployment✓ Correct
  • B. A single-AZ RDS instance with nightly snapshots
  • C. Self-managed database replication on EC2
  • D. DynamoDB with no backups
Explanation

RDS Multi-AZ maintains a synchronous standby in another AZ with automatic failover and no manual replication management. A single-AZ instance with snapshots (B) risks downtime and data loss, self-managed EC2 replication (C) adds operational burden, and DynamoDB with no backups (D) changes the data model and lacks protection.
