Amazon AWS Certified Solutions Architect - Associate SAA-C03 Prüfungsfragen mit Lösungen (Q919-Q924):

919. Frage
A gaming company is designing a highly available architecture. The application runs on a modified Linux kernel and supports only UDP-based traffic. The company needs the front-end tier to provide the best possible user experience. That tier must have low latency, route traffic to the nearest edge location, and provide static IP addresses for entry into the application endpoints.
What should a solutions architect do to meet these requirements?

A. Configure AWS Global Accelerator to forward requests to a Network Load Balancer. Use Amazon EC2 instances for the application in an EC2 Auto Scaling group.
B. Configure Amazon CloudFront to forward requests to a Network Load Balancer. Use AWS Lambda for the application in an AWS Application Auto Scaling group.
C. Configure Amazon API Gateway to forward requests to an Application Load Balancer. Use Amazon EC2 instances for the application in an EC2 Auto Scaling group.
D. Configure Amazon Route 53 to forward requests to an Application Load Balancer. Use AWS Lambda for the application in AWS Application Auto Scaling.

Antwort: A

920. Frage
A company hosts an Amazon EC2 instance in a private subnet in a new VPC. The VPC also has a public subnet that has the default route set to an internet gateway. The private subnet does not have outbound internet access.
The EC2 instance needs to have the ability to download monthly security updates from an outside vendor.
However, the company must block any connections that are initiated from the internet.
Which solution will meet these requirements?

A. Create a NAT instance in the private subnet. Configure the private subnet route table to use the NAT instance as the default route.
B. Create a NAT instance in the private subnet. Configure the private subnet route table to use the internet gateway as the default route.
C. Configure the private subnet route table to use the internet gateway as the default route.
D. Create a NAT gateway in the public subnet. Configure the private subnet route table to use the NAT gateway as the default route.

Antwort: D

Begründung:
Apublic NAT gatewayin a public subnet is the correct design because AWS states that instances in aprivate subnetcan use a NAT gateway foroutbound internet access, while the internetcannot initiate unsolicited inbound connectionsto those instances. That is exactly what the question requires: the instance must download vendor updates but remain unreachable from the internet. Routing the private subnet directly to the internet gateway would require public addressing and would break the isolation model. The NAT instance answers are weaker because they add operational management and, in these options, are placed incorrectly. Therefore, a NAT gateway in the public subnet with the private subnet default route pointed at the NAT gateway is the proper solution.

921. Frage
[Design Cost-Optimized Architectures]
A company has stored millions of objects across multiple prefixes in an Amazon S3 bucket by using the Amazon S3 Glacier Deep Archive storage class. The company needs to delete all data older than 3 years except for a subset of data that must be retained. The company has identified the data that must be retained and wants to implement a serverless solution.
Which solution will meet these requirements?

A. Use AWS Batch to delete objects older than 3 years except for the data that must be retained
B. Use S3 Inventory to list all objects. Use the AWS CLI to create a script that runs on an Amazon EC2 instance that deletes objects from the inventory list.
C. Enable S3 Inventory. Create an AWS Lambda function to filter and delete objects. Invoke the Lambda function with S3 Batch Operations to delete objects by using the inventory reports.
D. Provision an AWS Glue crawler to query objects older than 3 years. Save the manifest file of old objects. Create a script to delete objects in the manifest.

Antwort: C

Begründung:
To meet the requirement of deleting objects older than 3 years while retaining certain data, this solution leverages serverless technologies to minimize operational overhead.
S3 Inventory: S3 Inventory provides a flat file that lists all the objects in an S3 bucket and their metadata, which can be configured to include data such as the last modified date. This inventory can be generated daily or weekly.
AWS Lambda Function: A Lambda function can be created to process the S3 Inventory report, filtering out the objects that need to be retained and identifying those that should be deleted.
S3 Batch Operations: S3 Batch Operations can execute tasks such as object deletion at scale. By invoking the Lambda function through S3 Batch Operations, you can automate the process of deleting the identified objects, ensuring that the solution is serverless and requires minimal operational management.
Why Not Other Options?:
Option A (AWS CLI script on EC2): Running a script on an EC2 instance adds unnecessary operational overhead and is not serverless.
Option B (AWS Batch): AWS Batch is designed for running large-scale batch computing workloads, which is overkill for this scenario.
Option C (AWS Glue + script): AWS Glue is more suited for ETL tasks, and this approach would add unnecessary complexity compared to the serverless Lambda solution.
AWS Reference:
Amazon S3 Inventory- Information on how to set up and use S3 Inventory.
S3 Batch Operations- Documentation on how to perform bulk operations on S3 objects using S3 Batch Operations.

922. Frage
A company uses a 100 GB Amazon RDS for Microsoft SQL Server Single-AZ DB instance in the us-east-1 Region to store customer transactions. The company needs high availability and automate recovery for the DB instance.
The company must also run reports on the RDS database several times a year. The report process causes transactions to take longer than usual to post to the customer' accounts.
Which combination of steps will meet these requirements? (Select TWO.)

A. Take a snapshot of the current DB instance. Restore the snapshot to a new RDS deployment in another Availability Zone.
B. Use RDS Proxy to limit reporting requests to the maintenance window.
C. Migrate the database to RDS Custom.
D. Modify the DB instance from a Single-AZ DB instance to a Multi-AZ deployment.
E. Create a read replica of the DB instance in a different Availability Zone. Point All requests for reports to the read replica.

Antwort: D,E

923. Frage
A company hosts a marketing website in an on-premises data center. The website consists of static documents and runs on a single server. An administrator updates the website content infrequently and uses an SFTP client to upload new documents.
The company decides to host its website on AWS and to use Amazon CloudFront. The company's solutions architect creates a CloudFront distribution. The solutions architect must design the most cost-effective and resilient architecture for website hosting to serve as the CloudFront origin.
Which solution will meet these requirements?

A. Create a private Amazon S3 bucket. Use an S3 bucket policy to allow access from a CloudFront origin access identity (OAI). Upload website content by using theAWSCLI.
B. Create a virtual server by using Amazon Lightsail. Configure the web server in the Lightsail instance. Upload website content by using an SFTP client.
C. Create an AWS Auto Scaling group for Amazon EC2 instances. Use an Application Load Balancer. Upload website content by using an SFTP client.
D. Create a public Amazon S3 bucket. Configure AWS Transfer for SFTP. Configure the S3 bucket for website hosting. Upload website content by using the SFTP client.

Antwort: D
