- B. Create multiple AWS Site-to-Site VPN connections between AWS and branch offices in Europe and Australia for file uploads into the destination S3 bucket.
- C. Use multipart uploads for file uploads into the destination S3 bucket from the branch offices in Europe and Australia.
- D. Create multiple AWS Direct Connect connections between AWS and branch offices in Europe and Australia tor He uploads into the destination S3 bucket
- E. Use Amazon S3 Transfer Acceleration for file uploads into the destination S3 bucket.
Answer: C,E
Explanation:
To increase upload speeds into the S3 bucket from Europe and Australia, the SysOps administrator should use Amazon S3 Transfer Acceleration and multipart uploads. These methods are cost-effective and efficient.
* Amazon S3 Transfer Acceleration:
* This feature speeds up uploads by using the globally distributed edge locations of Amazon
* CloudFront. Data is routed to the closest edge location, which then forwards the data to the S3 bucket in the destination region.
* This reduces latency and increases the upload speed for large files.
* Multipart Uploads:
* Multipart upload allows you to upload a single large object as a set of parts. Each part is independently uploaded and can be uploaded in parallel.
* This method improves the upload efficiency and resiliency, especially for large files.
* Configuration Steps:
* Enable Transfer Acceleration on the S3 bucket through the AWS Management Console or AWS CLI.
* Implement multipart upload in the application or scripts used for uploading files.

Answer:
Explanation:
See the Explanation for solution.
Explanation:
Here are the steps to configure an Amazon S3 bucket to serve a static error page in the event of a failure at the primary site:
* Log in to the AWS Management Console and navigate to the S3 service in the us-east-2 Region.
* Find the existing S3 bucket named lab-751906329398-26023898.com and click on it.
* In the "Properties" tab, click on "Static website hosting" and select "Use this bucket to host a website".
* In "Index Document" field, enter the name of the object that you want to use as the index document, in this case, "index.html"
* In the "Permissions" tab, click on "Block Public Access", and make sure that "Block all public access" is turned OFF.
* Click on "Bucket Policy" and add the following policy to allow public read access:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PublicReadGetObject",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::lab-751906329398-26023898.com/*"
}
]
}
* Now navigate to the Amazon Route 53 service, and find the existing hosted zone named lab-751906329398-26023898.com.
* Click on the "A record" and update the routing policy to "Primary - Failover" and add the existing ALB as the primary record.
* Click on "Create Record" button and create a new secondary failover alias record for the domain lab-751906329398-26023898.com that routes traffic to the existing S3 bucket.
* Now, when the primary site (ALB) goes down, traffic will be automatically routed to the S3 bucket serving the static error page.
Note:
* You can use CloudWatch to monitor the health of your ALB.
* You can use Amazon S3 to host a static website.
* You can use Amazon Route 53 for routing traffic to different resources based on health checks.

NEW QUESTION # 40
A Sysops administrator wants to share a copy of a production database with a migration account. The production database is hosted on an Amazon RDS DB instance and is encrypted at rest with an AWS Key Management Service (AWS KMS) key that has an alias of What must the Sysops administrator do to meet these requirements with the LEAST administrative overhead?
- A. Take a snapshot of the RDS DB instance in the production account. Amend the KMS key policy of the production-rds-key KMS key to give access to the migration account's root user. Share the snapshot with the migration account.
- B. Create an RDS read replica in the migration account. Configure the KMS key policy to replicate the production-rds-key KMS key to the migration account.
- C. Use native database toolsets to export the RDS DB instance to Amazon S3. Create an S3 bucket and an S3 bucket policy for cross-account access between the production account and the migration account. Use native database toolsets to import the database from Amazon S3 to a new RDS DB instance.
- D. Take a snapshot of the RDS DB instance in the production account. Share the snapshot with the migration account. In the migration account, create a new KMS key that has an identical alias.
Answer: A
Explanation:
To share an encrypted Amazon RDS DB instance snapshot across accounts, the least administrative overhead involves directly managing permissions on the AWS KMS key and sharing the snapshot. Here's how to do it:
Take a Snapshot: Initiate a snapshot of your Amazon RDS DB instance in the production account. This captures the current state of the database.
Modify KMS Key Policy: Adjust the policy of the KMS key used for encryption (identified by the alias 'production-rds-key') to grant the kms:Decrypt permission to the migration account's root user. This step is crucial as it allows the migration account to use the same encryption key to decrypt the snapshot.
Share the Snapshot: Share the newly created snapshot with the migration account using the RDS console or AWS CLI. The migration account will now be able to see and use this snapshot to create a new RDS instance.
AWS Documentation Reference:
You can refer to the AWS documentation on sharing encrypted snapshots: Sharing Encrypted Snapshots.

NEW QUESTION # 42
A SysOps administrator is re-architecting an application. The SysOps administrator has moved the database from a public subnet, where the database used a public endpoint. into a private subnet to restrict access from the public network. After this change, an AWS Lambda function that requires read access to the database cannot connect to the database. The SysOps administrator must resolve this issue without compromising security.
Which solution meets these requirements?
- A. Create an AWS PrivateLink interface endpoint for the Lambda function. Connect to the database using its private endpoint.
- B. Move the database to a public subnet. Use security groups for secure access.
- C. Attach an 1AM role to the Lambda function with read permissions to the database.
- D. Connect the Lambda function to the database VPC. Connect to the database using its private endpoint.
Answer: D
Explanation:
To resolve the issue of an AWS Lambda function unable to connect to a database that has been moved to a private subnet, the Lambda function needs to be connected to the same VPC as the database. This is done by configuring the Lambda function with VPC access. This involves specifying the VPC, subnets, and security groups for the Lambda function so that it can communicate with the database using its private endpoint.
Option B is correct as it directly addresses the issue without compromising security. AWS documentation on configuring VPC access for Lambda provides guidance on this setup Configuring VPC Access for Lambda.
