Step 2.1:

Download the exam guide (SAA-C02)

Download the sample questions (SAA-C02)

Step 3 - Practise Tests:

Test - Strategy:

• Understand - try to understand the main points of the question ( read throw more than one time, if needed)
• Eliminate - remove Answer that are 100% wrong in your point of view
• Evaluate - think about the tradeoffs of the remaining answers. Consider what is said and what is implied.
• Select - select the correct answers (from your point of view; you will never be asked to select more than 2 and if you need to select more than one, the question will ask for it).
• Validate - check if your answer corresponse and fulfil the requirments of  the given question

Tips & Tricks:

Test - & Certification Domaintopics:

Domain 1 - Design Resilient Architectures

• Single AZ Answers are always incorrect
• No single point of failures
• High Availability -ne Fault Tolerant

Domain 2 - Design High-Performing Architectures

• Look always for caching options (ElastiCache)
• Know how and where to use autoscaling
• Selecting the best instance type (t vs m vs c) in regard of the Use Case (Compute, General Purpose -> Webserver vs. App - Server)

Domain 3 - Design Secure Applications and Architecutres

• Lock down Root - Account
• Security Group (doesn't have a dedicated deny state - stateless) vs. NACLs (Network Access Controll List - statefull)
• IAM Roles are in a security prospective always the right way to go

Domain 4 - Design Cost Optimized Architectures:

• For always on instances -> reserved instances is a good optins
• Serverless (Lambda, DynamoDB, S3, Fargate) is always the most cost effective option
• Selecting the best instance type (t vs m vs c) in regards to Costs
• Select the best cost effective storage type (gp2 vs io1)
• Cost Optimization Questions -> in most Cases you have 2 Options that will work, but one fits better in regards to costs.

No domain associated tips:

• For unstructured Data -> S3 is a good match
• Managed services are preferred (fits more than one domain)
• Mark question for later review
