CLF — Security and Compliance

Draw the responsibility boundaryClassify security and operational tasks across EC2, RDS, Lambda, and S3, then explain why the boundary moves by service model.Foundation18′Harden a result bucketCreate a simulated S3 bucket, block public access, enable encryption and versioning, then define a lifecycle rule.Foundation22′Instrument and diagnose a backlogInspect a seeded queue backlog, create a user-impact alarm, enable API audit evidence, and apply the correct remediation.Intermediate28′

CLF — Billing, Pricing, and Support

Choose the cost and support toolMatch estimation, analysis, thresholds, anomaly detection, detailed exports, account allocation, compliance evidence, and technical help to the correct AWS mechanism.Foundation18′

SAA — Design High-Performing Architectures

Build a two-AZ VPC skeletonUse simulated AWS CLI commands to create a VPC, subnets in distinct Availability Zones, an internet gateway, route table, route, and associations.Intermediate32′

SAA — Design Secure Architectures

Repair an IAM policyReplace wildcard data access with a scoped allow, preserve an explicit deny for insecure transport, and test evaluation outcomes.Intermediate28′

SAA — Design Resilient Architectures

Repair a fragile web architectureTurn a single-instance, single-zone workload into a simulated load-balanced, auto-scaled, multi-AZ application with a Multi-AZ database.Intermediate35′Assemble a serverless order flowCreate a DynamoDB table, queue, dead-letter queue, Lambda worker, and API to model durable asynchronous order processing.Intermediate34′Secure a CloudFormation templateAnalyze and repair a template so its S3 bucket has encryption, public-access blocking, versioning, and retention controls.Intermediate30′Highly available web applicationDesign a public application with global delivery, Layer 7 protection, two-AZ compute, decoupled work, durable data, and audit.StudioServerless order pipelineCreate an API that persists orders, accepts asynchronous work, fans out events, orchestrates a workflow, and emits telemetry.StudioElastic HPC platformDesign a Slurm-based platform with elastic compute, low-latency networking, parallel data, durable objects, identity/security, observability, and audit.StudioCost-aware global content serviceDeliver object content globally with caching, private service paths, serverless or elastic compute, and measurable cost controls.Studio

CLF — Cloud Technology and Services

Select storage from access patternsChoose object, block, shared NFS, SMB, archive, and ephemeral scratch services from workload descriptions.Foundation20′

CLF — Cloud Concepts

Choose a disaster-recovery strategySelect backup/restore, pilot light, warm standby, or multi-site patterns from explicit RTO, RPO, cost, and complexity constraints.Intermediate22′

SAA — Design Cost-Optimized Architectures

Optimize without breaking requirementsEvaluate architecture changes by unit cost, demand shape, transfer path, interruption tolerance, and recovery requirements.Intermediate24′

HPC — Compute and Scheduling

Choose an HPC orchestration modelSelect AWS PCS, ParallelCluster, AWS Batch, EKS patterns, or self-managed clusters from scheduler and operations requirements.Intermediate23′Schedule and inspect Slurm jobsCreate a simulated cluster, submit jobs and an array, advance scheduler time, and use queue/accounting commands to explain states.Intermediate34′

HPC — Network and Message Passing

Configure and verify an EFA clusterCreate a tightly coupled cluster with EFA, cluster placement, compatible software, and a communication benchmark.Advanced36′

HPC — Storage and Data

Stage, benchmark, and export HPC dataCreate an HPC cluster with a simulated parallel file system, stage an S3 dataset, run an I/O test, and export results durably.Advanced36′

HPC — Elasticity and Cost

Survive a Spot interruptionRun a simulated checkpointable job on Spot capacity, create a checkpoint, interrupt the job, and resume it without losing the completed work.Advanced32′

HPC — Parallel Foundations

Diagnose an HPC performance regressionUse layered evidence to identify whether a seeded regression is compute, placement, EFA, storage, scheduler, or data-staging related, then apply the narrow remediation.Advanced28′
