Which Route 53 routing policy directs traffic to the endpoint with the lowest network latency for the user?
Answer: Latency-based routing
Latency-based routing directs users to the AWS region that provides the lowest network latency based on actual measurements.
A solutions architect must ensure an S3 bucket policy prevents data from being publicly exposed even if a bucket ACL is misconfigured. Which feature addresses this?
Answer: S3 Block Public Access
S3 Block Public Access settings override bucket policies and ACLs to ensure buckets and objects are never publicly accessible.
Which AWS compute service is MOST appropriate for running a batch processing job that requires 10,000 vCPUs for two hours and then terminates?
Answer: AWS Batch with managed compute environments
AWS Batch automatically provisions the optimal quantity and type of compute resources and terminates them when the job completes.
An application uses DynamoDB and experiences hot partition issues during peak traffic. What is the BEST solution?
Answer: Use DynamoDB Accelerator (DAX) as a caching layer
DAX is an in-memory cache for DynamoDB that absorbs read traffic and reduces hot partition pressure without changing application code.
A company wants to enforce that all new EC2 instances must use approved AMIs. Which AWS service enforces this at scale?
Answer: AWS Config with a managed rule
AWS Config can evaluate EC2 instances against a rule that checks whether they use only approved AMI IDs and flags non-compliant resources.
Which disaster recovery strategy has the LOWEST RTO and RTO but also the HIGHEST cost?
Answer: Multi-Site Active/Active
Multi-Site Active/Active runs full-capacity environments in multiple regions simultaneously, providing near-zero RTO/RPO at the highest cost.
An architect needs to connect an on-premises data center to AWS with a consistent, dedicated 10 Gbps network connection. Which service provides this?
Answer: AWS Direct Connect
AWS Direct Connect provides a dedicated, private network connection between an on-premises data center and AWS at speeds up to 100 Gbps.
