Before you start: be comfortable with basic networking, identity, compute and storage. New to cloud? Start with the Cloud Practitioner path. These percentages describe the official exam’s scored content, not the number of lessons in each unit.

01

Translate a business requirement into an architecture

Separate availability, latency, durability and recovery requirements before choosing a service. Describe the workload, likely failure points, recovery time objective (RTO) and recovery point objective (RPO). Use the Well-Architected pillars as review questions, not a checklist of product names.

Your practice outputWrite a one-page design brief with a measurable requirement, one assumption and a failure test for each tier.

02

Design access with IAM, KMS and account boundaries

Trace who can assume a role, which actions are allowed and which resource or organization controls can deny them. Separate role trust from permissions. Work through encryption-key access, temporary credentials, secrets and least-privilege boundaries instead of granting broad administrative access.

Your practice outputExplain both the S3 object permission and the KMS permission a reporting role needs, then name a denied action it must not gain.

03

Connect private workloads and control network traffic

Follow a packet through subnet routes, security groups and network ACLs. Compare outbound internet access with private AWS service access. Choose a load balancer from the traffic protocol and routing requirement, and separate DNS routing from edge caching and network acceleration.

Your practice outputDraw the request and return paths for a private application, including its S3 route and the boundary that restricts inbound traffic.

04

Choose compute, scaling and asynchronous integration

Compare virtual machines, containers and functions against execution time, state, operational effort and load. Separate load distribution from capacity management. Use queues and events to isolate components, and reason about retries, duplicate delivery and failed-message handling.

Your practice outputSketch an order-processing flow with a queue, a retry-safe consumer and a way to investigate failed work.

05

Match storage and databases to access patterns

Decide whether a workload needs objects, block devices or shared files. Compare relational queries with key-value access, then examine throughput, latency, consistency, backups and recovery. Distinguish an RDS standby used for availability from a read replica used to offload suitable reads.

Your practice outputBuild a decision table for application files, transactional records and archive data, including one reason to reject an alternative.

06

Plan for failure and global delivery

Locate single points of failure across application and data tiers. Compare recovery strategies against RTO, RPO and budget. Explain what a backup restores, what replication protects and what it does not. Select DNS and edge services from the actual failover, caching or connection requirement.

Your practice outputWrite a failure walkthrough: what stops working, how the application reconnects, how data is recovered and how recovery is verified.

07

Optimize the full architecture cost

Right-size before making a spending commitment. Compare steady workloads with interruptible jobs, then consider storage retrieval, data transfer and network processing costs. Treat the cheapest component as only one part of the complete design; document the reliability or operational trade-off.

Your practice outputCompare two designs using the same workload assumptions and list the cost drivers you would verify in the AWS Pricing Calculator.

08

Defend a design and build your revision plan

Combine the earlier decisions in a small web-application design. Explain why the selected services satisfy the constraints and why plausible alternatives do not. Use a fresh practice set to find weak concepts, revisit a relevant guide and record the reasoning behind every correction.

Your practice outputProduce an architecture sketch, a trade-off log and a revision list based on mistakes, rather than memorized answer letters.

TRY THE ARCHITECTURE WORK

Four design exercises with explained decisions.

Read the constraint, sketch your approach and explain why an alternative fails. These are fictional learning scenarios, not customer incidents or recalled exam questions. No AWS account is needed.

EXERCISE 1 · Security

The report exists, but the application gets AccessDenied

An EC2 reporting application uses an IAM role in the same account as its private S3 bucket. The role can read the reports prefix. An object encrypted with a customer-managed KMS key still fails to download. Test objects using S3-managed encryption keys are readable, and no explicit deny has been identified.

Your design taskWhich additional permission path would you investigate before changing the bucket or network?

Review the decision: security

A reasoned approach. Check authorization for kms:Decrypt on the object's actual KMS key. The role's S3 read permission is only one part of the request; the KMS key policy must also permit the role directly or enable an appropriate IAM permission path.

Why the shortcut fails. Making the bucket public or attaching AdministratorAccess does not diagnose the missing authorization and would broaden access unnecessarily.

Check your work. Record the object encryption key, the calling role and the relevant key-policy and IAM statements. Explain why the role can read the allowed report but still cannot read a different prefix.

EXERCISE 2 · Resilience + performance

A resilient database still struggles with reporting traffic

A web shop uses an RDS PostgreSQL Multi-AZ DB instance deployment with one standby. It needs automatic failover for database availability, but daily reporting adds heavy read load. Reports can tolerate replication lag. A teammate suggests sending report queries to the standby endpoint.

Your design taskHow would you separate the availability requirement from the reporting requirement?

Review the decision: resilience + performance

A reasoned approach. Keep the Multi-AZ DB instance deployment for availability and evaluate a read replica for the lag-tolerant reporting workload. The single standby in this deployment does not serve reads. A Multi-AZ DB cluster is a different topology, so do not generalize this rule to every Multi-AZ option.

Why the shortcut fails. A read replica is not interchangeable with the automatic failover standby. Sending every query to a replica also ignores replication lag and read-after-write needs.

Check your work. Mark the writer and reporting endpoints on a sketch. Decide which queries require fresh committed data, which tolerate lag, and how clients reconnect after a writer failover.

EXERCISE 3 · Resilience

Retrying a queue message creates the same order twice

A worker receives an order request from an SQS standard queue. It commits the order, then crashes before deleting the message. Another worker later receives that request. The customer must not be charged twice, even if a message is delivered more than once.

Your design taskWhat must the application remember, and where should duplicate protection happen?

Review the decision: resilience

A reasoned approach. Use a stable business request ID and a durable, atomic idempotency check around the business effect. A retry should recognize completed work instead of creating a second order. SQS standard queues provide at-least-once delivery; consumers must handle possible duplicates.

Why the shortcut fails. Deleting the message before completing the order risks lost work. A larger visibility timeout alone cannot guarantee that duplicate delivery or a crash will never happen.

Check your work. Walk through crashes before the write, after the write and before message deletion. For a separate payment API, use its supported idempotency mechanism as well; a local database flag alone cannot make two systems atomic.

EXERCISE 4 · Cost + networking

Private S3 downloads are increasing NAT processing costs

EC2 instances in private subnets download large objects from a general purpose S3 bucket in the same Region. The traffic currently uses a NAT gateway. The instances still need outbound internet access for a separate dependency. There are no on-premises clients in this exercise.

Your design taskWhich route can remove this S3 traffic from the NAT path without making the instances public?

Review the decision: cost + networking

A reasoned approach. Evaluate an S3 gateway endpoint associated with the private subnet route tables. Same-Region S3 traffic can use that route without a NAT gateway, and the gateway endpoint has no additional endpoint charge. S3 storage and request charges still apply; other outbound internet traffic can continue using NAT.

Why the shortcut fails. An internet gateway alone does not give a private-address instance internet connectivity. An interface endpoint is not automatically the lowest-cost choice for this specific in-VPC S3 requirement.

Check your work. Identify the affected route tables and check endpoint, bucket and identity policies together. A network route is not permission to read an object. Do not remove the NAT path while the other dependency still needs it.

For optional hands-on practice, use only an authorized sandbox and sample data. Check pricing, set a budget alert and plan resource cleanup before deploying anything. A budget alert is not a spending cap.

LEARN → PRACTISE → REVIEW

Use three separate sets to check your progress.

195 original questions across 3 full-length sets. Review mistakes between attempts instead of immediately repeating the same answers.

Know the difference: these sets use single-choice questions. AWS’s official exam also includes multiple-response items. Practice percentages do not map directly to the AWS scaled passing score. Verify AWS exam format and preparation resources.

COURSE QUESTIONS

AWS Certified Solutions Architect - Associate FAQs

Clear answers about curriculum, audience, instructors, fees, and scheduling.

Is this AWS Solutions Architect Associate training for SAA-C03?

Yes. This independent ITCertPath preparation outline targets SAA-C03, with eight study units, four original architecture exercises and links to detailed concept guides. It is not an official AWS course or an AWS-endorsed question bank.

What is the SAA-C03 exam format?

AWS currently lists 65 multiple-choice or multiple-response questions with 130 minutes of exam time. The official guide describes 50 scored and 15 unscored questions and a minimum scaled passing score of 720. That scaled score is not a promise that 72% on a practice test predicts a pass. Verify the current AWS guide before booking.

Should I start with Cloud Practitioner or Solutions Architect Associate?

AWS recommends at least a year of hands-on AWS solution-design experience for the SAA target candidate. If networking, identity, compute and storage are new to you, use the Cloud Practitioner learning path to build those foundations first. Choose by your experience and learning gaps, not just the certification title.

Are all three AWS mock tests the same as the official exam?

No. The three ITCertPath sets each contain 65 original single-choice questions and a 130-minute timer, with scoring and explanations. The official exam also uses multiple-response questions. Our sets support concept revision but do not reproduce the live exam or predict its scaled score.

Do I need an AWS account for the exercises on this page?

No. The four design exercises can be completed on paper without deploying resources. Optional hands-on work needs an authorized sandbox, cost checks and a cleanup plan. These examples do not require you to use production data or incur cloud charges.

How do I confirm the AWS training schedule and what is included?

Ask ITCertPath to confirm the instructor, delivery format, taught syllabus, lab access, fees and your time zone before enrolling. Free study guides and practice tests are available separately. A course listing does not confirm an upcoming batch, include an exam voucher or award an AWS certification.
