Q.62 aNS:- A(VACUUM FULL Orders;) - Reclaim disk space: It reclaims space occupied by deleted rows.
Analyze the sort key column: By performing a full sort based on the interleaved sort key on the AWS Regions column, it ensures the data is optimally arranged for queries that utilize this column, making performance analysis of the sort key meaningful.

Excellent study material
5 questions are full interactive simulation questions where you need to read logs and determine root cause.
Most questions are direct questions and easy to answer if know how the terminology is used.
I had plenty of time answer them all and 30 min to review again.

QUESTION: 48
Answer is A not C
Why A is correct:
ALB terminates SSL at the front, using ACM-provided certificate.
SSL certificate is exported and installed on EC2s, so each EC2 also speaks HTTPS.
Traffic is encrypted both ways (client ? ALB and ALB ? EC2) — end-to-end encryption is ensured.
Why C is incorrect:
C: Sounds similar to A, but mentions a third-party SSL certificate, which adds unnecessary complexity. Also, ACM can’t export certificates for use outside of AWS — only imported certificates can be exported.

An e-learning platform needs to run an application for 2 months each year. The application will be deployed on Amazon EC2 instances. Any application downtime during those 2 months must be avoided.
Which EC2 purchasing option will meet these requirements MOST cost-effectively?
Reserved Instances
Dedicated Hosts
Spot Instances
On-Demand Instances
the answer should be Reserved instance. Please update

@Gct, to be honest with you I did not want to take the chance and fail. Because the free version gives you access to half of the questions. The full version has all of the questions from the Microsoft Question Bank. So it is up to you.

QUESTION: 44
Answer is A not B
Why A is correct:
AWS Lambda function URLs allow you to directly invoke a Lambda function without needing API Gateway or any other proxy.
Fully serverless and easy to manage.
Minimal setup: just assign a URL to each Lambda function and update Git server webhooks.
Lowest operational overhead — no need to manage gateways, load balancers, or containers.
Why B is more overhead
B. API Gateway HTTP API + Lambda:
Also serverless, but adds API Gateway as an additional layer, increasing configuration and cost compared to Lambda function URLs.

QUESTION: 43
The Answer is D not C
Why D is correct:
Service Control Policies (SCPs) are enforced at the organization level via AWS Organizations.
Denying the action ec2:AuthorizeSecurityGroupIngress based on a condition (i.e., aws:SourceIp == 0.0.0.0/0) ensures:
No such rule can be created — proactive control.
Applied to all accounts in the NonProd OU centrally.
No need for Lambda functions, event triggers, or post-creation rollbacks — meaning lowest operational overhead.
C is incorrect
C. SCP allowing non-0.0.0.0/0:
You can't allow specific condition-based actions in SCPs. SCPs are deny-based only (allow by omission).

Passed yesterday with score of 773.
this dump is roughly 50% valid for unpaid version. I got 3 PBQ which are host infections and autoscaling and one new i have not seen before.
Question: Recent system breach due to password, choose the best password practices and what mitigation will prevent it from happening again?
Password protection standard: Reuse, Complexity, Length, Expiration, Age (you can choose any possible combination, no limit)
Answer: Reuse, Expiration, length (as per comptia, age and complexity are not best password practices)
Mitigation: FIDO Hardware, PIN, Password, SMS OTP
Answer: FIDO Hardware
I came across one youtube channel a few days before my exams. He thoroughly explains every PBQs. All his questions are literally form dumps. I HIGHLY recommend to check it out.

QUESTION: 28
Answer is C not A
To accurately track costs for resources across AWS Organizations using user-defined tags, the following must happen:
1. Activate the tag ("costCenter") in each member account:
Tags must be activated at the account level for them to be used in billing and cost allocation.
Without activation, AWS will not include them in the Cost and Usage Reports (CUR).
2. Generate the AWS Cost and Usage Report (CUR) from the management account:
The management account in AWS Organizations is the only one that can see the full consolidated billing data across accounts.
CUR includes tag breakdowns (if tags are activated in member accounts).
3. Use tag breakdowns in the CUR:
This allows precise cost allocation based on the costCenter=compliance tag.
