Question 12mediummultiple choice
Full question →A company has 50 TB of historical data stored on on-premises network-attached storage (NAS). The company wants to transfer this data to Amazon S3. The internet connection provides only 10 Mbps upload speed, and the company wants to complete the transfer within 2 weeks. The data is not sensitive and does not require encryption during transfer. Which AWS service should the company use to meet these requirements?
Question 13mediummultiple choice
Full question →A company has 50 TB of on-premises file server data that must be transferred to Amazon S3. The company's internet connection is limited to 100 Mbps, and the data transfer must not impact daily business operations. The company needs a physical device to securely copy the data and then ship it to AWS for ingestion. Which AWS service should the company use?
Question 14mediummultiple choice
Full question →A company based in Germany needs to store and process customer data that, by law, must remain within the European Union (EU). The company plans to use AWS services. Which AWS Global Infrastructure element is the MOST important for the company to evaluate when choosing where to deploy its resources?
Question 15mediummultiple choice
Full question →A company has 200 IAM users. The security team needs to automatically verify that every IAM user has enabled multi-factor authentication (MFA) for console access. They also need to receive a notification whenever a new user is created without MFA so they can enforce the policy. Which AWS service should the security team use to meet these requirements?
Question 16mediummultiple choice
Full question →A company has a compliance policy requiring that all Amazon EC2 instances in its production environment must have the tag "Environment=Production" and must be associated with a security group named "Prod-SG".
