Amazon AWS Certified Solutions Architect - Professional Sample Questions (Q281-Q286):NEW QUESTION # 281
A customer has a 10 GB AWS Direct Connect connection to an AWS region where they have a web application hosted on Amazon Elastic Computer Cloud (EC2). The application has dependencies on an on-premises mainframe database that uses a BASE (Basic Available, Soft state, Eventual consistency) rather than an ACID (Atomicity, Consistency, Isolation, Durability) consistency model. The application is exhibiting undesirable behavior because the database is not able to handle the volume of writes.
How can you reduce the load on your on-premises database resources in the most cost-effective way?
  • A. Modify the application to write to an Amazon SQS queue and develop a worker process to flush the queue to the on-premises database.
  • B. Use an Amazon Elastic Map Reduce (EMR) S3DistCp as a synchronization mechanism between the on-premises database and a Hadoop cluster on AWS.
  • C. Provision an RDS read-replica database on AWS to handle the writes and synchronize the two databases using Data Pipeline.
  • D. Modify the application to use DynamoDB to feed an EMR cluster which uses a map function to write to the on-premises database.
Answer: B

NEW QUESTION # 282
An advisory firm is creating a secure data analytics solution for its regulated financial services users Users will upload their raw data to an Amazon 53 bucket, where they have PutObject permissions only Data will be analyzed by applications running on an Amazon EMR cluster launched in a VPC The firm requires that the environment be isolated from the internet All data at rest must be encrypted using keys controlled by the firm Which combination of actions should the Solutions Architect take to meet the user's security requirements?
(Select TWO )
  • A. Launch the Amazon EMR cluster in a private subnet configured to use an AWS CloudHSM appliance for at-rest encryption Configure a gateway VPC endpoint for Amazon S3 and an interface VPC endpoint for CloudHSM
  • B. Configure the S3 endpoint policies to permit access to the necessary data buckets only
  • C. Launch the Amazon EMR cluster in a private subnet configured to use an AWS KMS CMK for at-rest encryption Configure a gateway VPC endpomint for Amazon S3 and a NAT gateway to access AWS KMS
  • D. Configure the S3 bucket polices lo permit access using an aws sourceVpce condition lo match the S3 endpoint ID
  • E. Launch the Amazon EMR cluster m a private subnet configured to use an AWS KMS CMK for at-rest encryption Configure a gateway VPC endpoint (or Amazon S3 and an interlace VPC endpoint for AWS KMS
Answer: A,E

NEW QUESTION # 283
A company hosts a blog post application on AWS using Amazon API Gateway, Amazon DynamoDB, and AWS Lambda. The application currently does not use API keys to authorize requests. The API model is as follows:
GET/posts/[postid] to get post details
GET/users[userid] to get user details
GET/comments/[commentid] to get comments details
The company has noticed users are actively discussing topics in the comments section, and the company wants to increase user engagement by marking the comments appears in real time.
Which design should be used to reduce comment latency and improve user experience?
  • A. Modify the blog application code to request GET comment[commented] every 10 seconds.
  • B. Use AWS AppSync and leverage WebSockets to deliver comments.
  • C. Use edge-optimized API with Amazon CloudFront to cache API responses.
  • D. Change the concurrency limit of the Lambda functions to lower the API response time.
Answer: B
Explanation:
Explanation
https://docs.aws.amazon.com/apps ... aphql-overview.html AWS AppSync is a fully managed GraphQL service that allows applications to securely access, manipulate, and receive data as well as real-time updates from multiple data sources1. AWS AppSync supports GraphQL subscriptions to perform real-time operations and can push data to clients that choose to listen to specific events from the backend1. AWS AppSync uses WebSockets to establish and maintain a secure connection between the clients and the API endpoint2. Therefore, using AWS AppSync and leveraging WebSockets is a suitable design to reduce comment latency and improve user experience.

Answer: B

NEW QUESTION # 285
An organization is planning to setup a management network on the AWS VPC. The organization is trying
to secure the webserver on a single VPC instance such that it allows the internet traffic as well as the
back-end management traffic. The organization wants to make so that the back end management network
interface can receive the SSH traffic only from a selected IP range, while the internet facing webserver will
have an IP address which can receive traffic from all the internet IPs.
How can the organization achieve this by running web server on a single instance?
  • A. The organization should create two network interfaces with separate subnets so one instance can have
    two subnets and the respective security groups for controlled access.
  • B. It is not possible to have two IP addresses for a single instance.
  • C. The organization should create two network interfaces with the same subnet and security group to
    assign separate IPs to each network interface.
  • D. The organization should launch an instance with two separate subnets using the same network
    interface which allows to have a separate CIDR as well as security groups.
Answer: A
Explanation:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the
user to launch AWS resources into a virtual network that the user has defined. An Elastic Network
Interface (ENI) is a virtual network interface that the user can attach to an instance in a VPC.
The user can create a management network using two separate network interfaces. For the present
scenario it is required that the secondary network interface on the instance handles the public facing
traffic and the primary network interface handles the back-end management traffic and it is connected to a
separate subnet in the VPC that has more restrictive access controls. The public facing interface, which
may or may not be behind a load balancer, has an associated security group to allow access to the server
from the internet while the private facing interface has an associated security group allowing SSH access
only from an allowed range of IP addresses either within the VPC or from the internet, a private subnet
within the VPC or a virtual private gateway.
