Design solutions for organizational complexity

Compliance requires that EC2 instances reach AWS service APIs such as S3 and Systems Manager without any traffic leaving the AWS network for the public internet. Which setup accomplishes this?
A company runs twelve AWS accounts under one management account and wants all usage charges rolled into a single invoice, so that heavy usage in one account lowers the effective per-unit rate for the others. Which feature delivers this?
A holding company runs about 300 AWS accounts. Finance wants monthly chargeback reports grouped by a cost center label, and alerts when daily spend suddenly rises. Which combination is MOST appropriate?

Design for new solutions

A loyalty platform needs transactional writes with strong consistency, and its catalog reads reach millions per second with microsecond responses for hot items. Which architecture fits?
An energy trading firm receives tens of thousands of price updates per second from several exchanges. Updates for any single contract must be consumed strictly in arrival order, the pipeline must survive a full regional outage with minimal data loss, and every raw update must be retained for seven years for audits. Which design best satisfies these needs?
A travel company wants a voice and text booking assistant that recognizes intents and slot values, asks follow-up questions when details are missing, and calls its reservation APIs. Which pairing fits best?
A research institute keeps petabytes of instrument logs in S3. Analysts need serverless SQL over that data, table definitions maintained centrally, and column-level permissions enforced in one place. Which service fits BEST?
An administrator must change the EC2 instance size of an EBS-backed SAP HANA host during a maintenance window while keeping its private IP, ENI, and attached volumes. What should the administrator do?
A company wants external partners to use SAP GUI without installing and maintaining the client on every partner workstation. Which AWS service fits?
Which Linux file system does SAP recommend for HANA data and log volumes on AWS?
An architect must compare an on-premises SAP system with candidate EC2 sizes. Which unit provides a hardware-independent performance comparison?
An SAP system exposes OData services that external systems must call through a managed endpoint with throttling, authentication, and usage controls. Which service should front those services?
One HANA installation on a single EC2 instance must host separate development, quality and production databases, each with its own users, schemas and backup history and its own start and stop control, while sharing the host's CPU and memory. Which HANA capability delivers this?
A landscape includes a non-ABAP side application and a BI repository that the vendor says can use PostgreSQL. The team wants to run them on Aurora PostgreSQL-compatible. What must be confirmed first?

Continuous improvement for existing solutions

A company wants any S3 bucket that becomes publicly readable to be detected and returned to a compliant state automatically. Which approach meets this need?
A data pipeline in private subnets reads about 40 TB per month from an S3 bucket in the same Region. The monthly bill shows large per-GB charges for NAT gateway processing. Which change removes most of this cost without changing the pipeline code?
A checkout service calls an inventory service synchronously. When inventory slows down, checkout threads wait until they time out, and within minutes every service on the platform stops responding. Which set of design changes MOST effectively contains this failure?
A legacy app has four problems: web servers hit 90 percent CPU during office hours; the database rejects new connections at its limit; user sessions are held in web server memory, so users are logged out on every deploy; and each release needs two hours of downtime. Which single design fixes all four?
A finance manager wants to break down last year's EC2 and S3 spending by linked account and by cost allocation tag, view the trend in charts, and see a forecast for next quarter. Which tool should be used?
A reporting database on RDS for MySQL shows rising read latency while CPU stays near 20 percent. Freeable memory keeps falling and read IOPS climb whenever the large reports run. What is the most likely cause and the best fix?
Users report sporadic slowness in an application built from API Gateway, Lambda and DynamoDB. The engineers need to see how much time each component adds to an individual request. Which AWS service should they adopt?
After a lift-and-shift, a web tier runs in one Availability Zone and keeps each user's session on a particular server through load balancer stickiness. The team must improve availability first. Which change should come first?
A payments API runs on Amazon ECS behind an Application Load Balancer. Each release replaces every task at once, and a faulty build has repeatedly caused outages for customers. The team wants to limit the blast radius of bad releases. What should it change?
An internal reporting service on EC2 reads its database password from a file on disk, and an audit found that anyone with shell access can read it. The company wants encrypted storage, automatic rotation, and access logging tied to the instance's identity. What should the team do?
A ticketing system stores all open-ticket records in one DynamoDB table whose partition key is the status field, which can only be open, pending, or closed. CloudWatch shows throttling on the table during peak support hours. Which fix addresses the root cause?
A BW/4HANA system needs to keep infrequently accessed but still queried data out of HANA memory while leaving it available inside the database. Which feature should be used?
HANA write performance degrades every few minutes. Traces show savepoint duration climbing and users see short write stalls, while CPU and network look normal. Which layer should be investigated first?
A standalone SAP application server on EC2 occasionally loses its underlying host. The team wants automatic recovery that keeps the instance ID, private IP and attached volumes. Which mechanism fits?

Accelerate workload migration and modernization

A company has a large monolith with tightly coupled modules, a commercial Oracle database, shared file storage, hardcoded server addresses, and Windows-only components. It wants to move to microservices on AWS with low business risk. Which approach is most appropriate?
Which migration approach moves an application to AWS as it runs today, with no code or architecture changes?
An enterprise runs vSphere-based data centers and wants to move those workloads to AWS while keeping its vCenter, NSX and existing VMware operations unchanged. Which offering fits?
A 50 TB PostgreSQL database must move to Aurora PostgreSQL, and the business allows only a few minutes of downtime at cutover. Which approach fits?
An insurer writes nightly backups to a physical tape library through its backup application. It wants to retire the library, keep its existing backup software and workflows, and store long-term retention data in low-cost archival storage. Which option meets these goals?
A defense agency must host a classified workload in a fully isolated environment with no connection to the public internet and infrastructure dedicated to that classification level. Encryption keys must be stored in hardware modules validated to FIPS 140-2 Level 3. Which deployment meets all of these requirements?
A company will move an SAP system from Oracle to SAP HANA and must also perform the Unicode conversion. Which SAP tool covers the database change and conversion in one run?
After migrating SAP to AWS, the team must prove the new system performs at least as well as the source. Which comparison is objective?
An ECC system on anyDB must move to AWS and be converted to S/4HANA with only a very short outage. SAP's service-based near-zero downtime approach should be part of the plan. Which combination fits?
