1. A company plans to migrate its legacy application to AWS. The application is data-intensive and requires low-latency access for users across the globe. What AWS services and architecture would you recommend to ensure high availability and low latency?
Why you might get asked this:
Interviewers pose this aws interview questions and answers for experienced scenario based item to evaluate how you balance performance, resiliency, and cost during a full-scale migration. They want to see if you understand multi-AZ deployments, global content delivery, and data store selection for latency-sensitive workloads. Your answer reveals familiarity with lift-and-shift hurdles such as data replication, DNS routing, and user-experience metrics in multiple regions.
How to answer:
Begin by outlining core requirements—global reach, millisecond latency, and high availability. Propose a multi-tier solution: EC2 Auto Scaling groups in several Availability Zones, Amazon RDS Multi-AZ or Aurora Global Database for relational data, S3 for object storage, and CloudFront paired with Route 53 latency-based routing. Mention migration tools like AWS Database Migration Service and SCT. Tie back to business outcomes such as minimal downtime, faster page loads, and predictable costs.
Example answer:
“In a recent migration, we started by cloning the legacy stack onto EC2 instances distributed across three AZs, fronted by an Application Load Balancer. For global reach we turned on Amazon CloudFront with regional edge caches, cutting media latency by 45 %. Data sat in Aurora Global Database with automatic cross-region replication, meeting our RPO of under one second. S3 stored static assets and we used AWS DMS for continuous data replication until the final cut-over. Route 53 latency-based routing ensured users hit the nearest edge, keeping round-trip times below 100 ms. This end-to-end design hit our SLA while capping additional spend at 12 %, which demonstrates the kind of solution-first thinking interviewers seek in aws interview questions and answers for experienced scenario based discussions.”
2. Your organization wants to implement a disaster recovery plan for its critical AWS workloads with an RPO of 5 minutes and an RTO of 1 hour. Describe the AWS services you would use to meet these objectives.
Why you might get asked this:
This aws interview questions and answers for experienced scenario based prompt checks if you can translate recovery objectives into actionable architecture. It gauges your knowledge of cross-region replication, automated failover, backup orchestration, and infrastructure-as-code. Proving you can design for business continuity shows you understand operational excellence in the AWS Well-Architected Framework.
How to answer:
State the RPO/RTO targets and map them to a pilot light or warm standby strategy. Recommend AWS Backup with frequent snapshots, RDS Multi-AZ plus cross-region read replicas, S3 Cross-Region Replication, and CloudFormation or Terraform for infra redeploy. Explain failover automation using Route 53 health checks and Lambda functions. Emphasize testing through AWS Fault Injection Simulator and regular DR drills.
Example answer:
“I’d build a warm-standby setup. Databases run on RDS Multi-AZ in the primary region and maintain cross-region asynchronous replicas updated every couple of seconds, giving us a sub-5-minute RPO. For EC2, AMIs and EBS snapshots land in AWS Backup vaults replicated to a secondary region. CloudFormation templates recreate networking and security layers in about 20 minutes, leaving 40 minutes for data validation and DNS cut-over using Route 53. We rehearsed the plan quarterly; the last drill restored full service in 34 minutes, comfortably beating the 1-hour RTO. That practical approach aligns with what interviewers want in aws interview questions and answers for experienced scenario based evaluations.”
3. Consider a scenario where you need to design a scalable and secure web application infrastructure on AWS that handles sudden spikes in traffic and protects against DDoS attacks. What AWS services and features would you use?
Why you might get asked this:

Interviewers evaluate whether you can design event-driven architectures that accommodate unpredictable spikes without over-provisioning, all central to aws interview questions and answers for experienced scenario based sessions.
How to answer:
Describe ingest using AWS IoT Core, then route data to Kinesis Data Streams or Firehose. Use Lambda for transformation, store hot data in DynamoDB or Timestream, and archive to S3. Show how auto-sharding in Kinesis and Lambda’s concurrency scaling meet demand. Discuss using CloudWatch and Application Auto Scaling to adjust shard counts automatically.
Example answer:
“We connected each sensor to AWS IoT Core MQTT endpoints for secure ingestion. Messages flowed into Kinesis Data Streams, starting with four shards. A Lambda consumer normalized payloads and wrote time-series metrics to Timestream while sending raw data to S3 Glacier for long-term audit. Because Kinesis supports on-the-fly shard splitting, we used a CloudWatch rule that doubled shards once incoming PutRecords exceeded 75 % throughput, letting us scale from 5 MBps to 70 MBps in minutes. The pipeline cost less than one dollar per million messages—proof that thoughtful design meets both scale and budget, a hallmark of strong aws interview questions and answers for experienced scenario based performance.”

Recommend rightsizing via Compute Optimizer, purchasing Reserved or Savings Plans for steady workloads, and shifting bursty jobs to Spot. Automate shutdown for idle dev instances with Lambda.
Example answer:
“When a daily Cost Explorer alert flagged a 60 % EC2 jump, I pivoted to the cost-and-usage report and traced spend to an Auto Scaling group stuck at max capacity due to a misconfigured health check. We patched the check, culled 40 t3.large instances, then bought Convertible Savings Plans covering 70 % of baseline usage, saving $18k annually. Finally, I set a Lambda scheduler to stop dev servers overnight. That blend of detective work and optimization embodies what the panel seeks in aws interview questions and answers for experienced scenario based settings.”
7. How does auto-scaling work in AWS?
Why you might get asked this:
Auto Scaling is foundational for elasticity and cost efficiency. Interviewers confirm you understand scaling triggers, cooldowns, and integration with Load Balancers or Spot. Explaining nuanced behaviors proves on-call credibility.
How to answer:
Describe dynamic, scheduled, and predictive scaling. Discuss CloudWatch metrics, step policies, target tracking, lifecycle hooks, and Instance Refresh. Highlight scaling across multiple AZs and tying Auto Scaling to Spot Fleets for savings.
Example answer:
“I explain Auto Scaling as a thermostat for compute: CloudWatch monitors metrics like CPU, request count, or custom latency, and policies call the Auto Scaling API to add or remove instances. In production, we pair step policies with lifecycle hooks that route new instances through SSM patching before entering service. Predictive scaling forecasted our Monday traffic spike, provisioning capacity 30 minutes early, trimming 12 % latency. That practical insight resonates well in aws interview questions and answers for experienced scenario based evaluations.”
8. What is VPC, and how do you configure it?
Why you might get asked this:
Network design underpins security. This question checks if you can isolate resources, route traffic, and follow CIDR best practices—elements often overlooked by candidates focused solely on compute.
