Q2. A user is making a scalable web application with compartmentalization. The user wants the log module to be able to be accessed by all the application functionalities in an asynchronous way. Each module of the application sends data to the log module, and based on the resource availability it will process the logs. Which AWS service helps this functionality?
A. AWS Simple Queue Service.
B. AWS Simple Notification Service.
C. AWS Simple Workflow Service.
D. AWS Simple Email Service.
Answer: A
Explanation:
Amazon Simple Queue Service (SQS) is a highly reliable distributed messaging system for storing messages as they travel between computers. By using Amazon SQS, developers can simply move data between distributed application components. It is used to achieve compartmentalization or loose coupling. In this case all the modules will send a message to the logger queue and the data will be processed by queue as per the resource availability.

D. It's a security tool that allows to "freeze" an EC2 instance and perform computer forensics on it.
Answer: C
Q5. Your firm has uploaded a large amount of aerial image data to 53 In the past, in your on-premises environment, you used a dedicated group of servers to oaten process this data and used Rabbit MOAn open source messaging system to get job information to the servers. Once processed the data would go to tape and be shipped offsite. Your manager told you to stay with the current design, and leverage AWS archival storage and messaging services to minimize cost. Which is correct?
A. Use SOS for passing job messages use Cloud Watch alarms to terminate EC2 worker instances when they become idle. Once data is processed, change the storage class of the 53 objects to Reduced Redundancy Storage.
B. Setup Auto-Scaled workers triggered by queue depth that use spot instances to process messages in SOS Once data is processed,
C. Change the storage class of the 53 objects to Reduced Redundancy Storage. Setup Auto-Scaled workers triggered by queue depth that use spot instances to process messages in SOS Once data is processed, change the storage class of the 53 objects to Glacier.
D. Use SNS to pass job messages use Cloud Watch alarms to terminate spot worker instances when they become idle. Once data is processed, change the storage class of the 53 object to Glacier.
Answer: D
Q6. A user has launched a large EBS backed EC2 instance in the US-East-1a region. The user wants to achieve Disaster Recovery (DR) for that instance by creating another small instance in Europe. How can the user achieve DR?
A. Copy the instance from the US East region to the EU region
B. Use the "Launch more like this" option to copy the instance from one region to another
C. Copy the running instance using the "|nstance Copy" command to the EU region
D. Create an AMI of the instance and copy the AMI to the EU region. Then launch the instance from the EU AMI
Answer: D
Explanation:
To launch an EC2 instance it is required to have an AMI in that region. If the AMI is not available in that region, then create a new AMI or use the copy command to copy the AMI from one region to the other region.

Q7. The common use cases for DynamoDB Fine-Grained Access Control (FGAC) are cases in which the end user wants .
A. to change the hash keys of the table directly
B. to check if an IAM policy requires the hash keys of the tables directly
C. to read or modify any codecommit key of the table directly, without a middle-tier service
D. to read or modify the table directly, without a middle-tier service
Answer: D
Explanation:
FGAC can benefit any application that tracks information in a DynamoDB table, where the end user (or application client acting on behalf of an end user) wants to read or modify the table directly, without a middle-tier service. For instance, a developer of a mobile app named Acme can use FGAC to track the
top score of every Acme user in a DynamoDB table. FGAC allows the application client to modify only the top score for the user that is currently running the application.

Q8. You are trying to launch an EC2 instance, however the instance seems to go into a terminated status immediately. What would probably not be a reason that this is happening?
A. The AMI is missing a required part.
B. The snapshot is corrupt.
C. You need to create storage in EBS first.
D. You've reached your volume limit.
Answer: C
Explanation:
Amazon EC2 provides a virtual computing environments, known as an instance.
After you launch an instance, AWS recommends that you check its status to confirm that it goes from the pending status to the running status, the not terminated status.
The following are a few reasons why an Amazon EBS-backed instance might immediately terminate: You've reached your volume limit.
The AM is missing a required part. The snapshot is corrupt. Reference:

Q14. You need to set up security for your VPC and you know that Amazon VPC provides two features that you can use to increase security for your VPC: security groups and network access control lists (ACLs). You have already looked into security groups and you are now trying to understand ACLs. Which statement below is incorrect in relation to ACLs?
A. Supports allow rules and deny rules.
B. Is stateful: Return traffic is automatically allowed, regardless of any rules.
C. Processes rules in number order when deciding whether to allow traffic.
D. Operates at the subnet level (second layer of defense).
Answer: B
Explanation:
Amazon VPC provides two features that you can use to increase security for your VPC:
Security groups—Act as a firewall for associated Amazon EC2 instances, controlling both inbound and outbound traffic at the instance level
Network access control lists (ACLs)—Act as a firewall for associated subnets, controlling both inbound and outbound traffic at the subnet level
Security groups are stateful: (Return traffic is automatically allowed, regardless of any rules) Network ACLs are stateless: (Return traffic must be explicitly allowed by rules)
