Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q73-Q78):

NEW QUESTION # 73
A company is developing a microservices-based application to manage the company ' s delivery operations.
The application consists of microservices that process orders, manage a fleet of delivery vehicles, and optimize delivery routes.
The microservices must be able to scale independently and must be able to handle bursts of traffic without any data loss.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: C

Explanation:
Amazon SQS is a fully managed message queuing service that reliably decouples and scales microservices, distributed systems, and serverless applications. By using SQS, microservices can communicate asynchronously, handle bursts of traffic, and avoid data loss by buffering messages until they are processed.
Deploying the services on ECS with AWS Fargate further reduces operational overhead by removing the need to manage servers, allowing independent scaling of each microservice.
Reference Extract:
" Amazon SQS decouples application components and enables message durability and scaling. AWS Fargate removes the need to manage infrastructure, supporting independent scaling and minimal operational overhead.
"

NEW QUESTION # 74
A company runs several custom applications on Amazon EC2 instances. Each team within the company manages its own set of applications and backups. To comply with regulations, the company must be able to report on the status of backups and ensure that backups are encrypted.
Which solution will meet these requirements with the LEAST effort?

Answer: C

Explanation:
AWS Backup Audit Manager automates auditing and reporting of backup activity and compliance, while AWS Config provides visibility into configuration changes. Together, they provide the simplest, most automated, and compliant backup monitoring solution.
"AWS Backup Audit Manager automatically audits backup activity across AWS resources. You can use predefined or custom frameworks to monitor backup compliance and encryption status." Why D is correct:
Ensures centralized visibility into all backup jobs.
Verifies encryption status automatically.
Generates ready-to-use reports with minimal operational overhead. Complies with regulatory requirements for data protection.
Why others are incorrect:
A & C: Custom Lambda automation increases maintenance effort.
B: Manual checking is operationally inefficient and error-prone.


NEW QUESTION # 75
[Design High-Performing Architectures]
A solutions architect must design a highly available infrastructure for a website. The website is powered by Windows web servers that run on Amazon EC2 instances. The solutions architect mustimplement a solution that can mitigate a large-scale DDoS attack that originates from thousands of IP addresses. Downtime is not acceptable for the website.
Which actions should the solutions architect take to protect the website from such an attack? (Select TWO.)

Answer: B,C

Explanation:
(https://aws.amazon.com/cloudfront


NEW QUESTION # 76
A solutions architect is developing a multiple-subnet VPC architecture. The solution will consist of six subnets in two Availability Zones. The subnets are defined as public, private and dedicated for databases.
Only the Amazon EC2 instances running in the private subnets should be able to access a database.
Which solution meets these requirements?

Answer: B

Explanation:
Security groups are stateful. All inbound traffic is blocked by default. If you create an inbound rule allowing traffic in, that traffic is automatically allowed back out again. You cannot block specific IP address using Security groups (instead use Network Access Control Lists).
"You can specify allow rules, but not deny rules." "When you first create a security group, it has no inbound rules. Therefore, no inbound traffic originating from another host to your instance is allowed until you add inbound rules to the security group." Source: https://docs.aws.amazon.com/vpc/latest/userguide

NEW QUESTION # 77
[Design Operationally Excellent Architectures]
A company wants to run big data workloads on Amazon EMR. The workloads need to process terabytes of data in memory.
A solutions architect needs to identify the appropriate EMR cluster instance configuration for the workloads.
Which solution will meet these requirements?

Answer: D

Explanation:
Big data workloads that need to process terabytes of data in memory requirememory-optimized instancesfor the core and task nodes to ensure sufficient memory for processing data efficiently.
Primary Node:Ageneral purpose instanceis suitable because it manages cluster operations, including coordination and monitoring, and does not process data directly.
Core and Task Nodes:These nodes handle data storage and processing.Memory-optimized instancesare ideal because they provide high memory-to-CPU ratios, which is critical for in-memory big data workloads.
Why Other Options Are Incorrect:
Option A:Storage optimized and compute optimized instances are not suitable for workloads that rely heavily on in-memory processing.
Option B:A memory-optimized primary node is unnecessary because the primary node does not process data.
Option D:General purpose instances for all nodes will not provide sufficient memory for processing terabytes of data in memory.

Memory-Optimized Instances
