NEW QUESTION 1
A company has an existing on-premises three-tier web application. The Linux web servers serve content from a centralized file share on a NAS server because the content is refreshed several times a day from various sources. The existing infrastructure is not optimized and the company would like to move to AWS in order to gain the ability to scale resources up and down in response to load. On-premises and AWS resources are connected using AWS Direct Connect.
How can the company migrate the web infrastructure to AWS without delaying the content refresh process?

• A. Create a cluster of web server Amazon EC2 instances behind a Classic Load Balancer on AW
• B. Share an Amazon EBS volume among all instances for the conten
• C. Schedule a periodic synchronization of this volume and the NAS server.
• D. Create an on-premises file gateway using AWS Storage Gateway to replace the NAS server and replicate content to AW
• E. On the AWS side, mount the same Storage Gateway bucket to each web server Amazon EC2 instance to serve the content.
• F. Expose an Amazon EFS share to on-premises users to serve as the NAS serv
• G. Mount the same EFS share to the web server Amazon EC2 instances to serve the content.
• H. Create web server Amazon EC2 instances on AWS in an Auto Scaling grou
• I. Configure a nightly process where the web server instances are updated from the NAS server.

Answer: C

Explanation:
File gateway is limited by performance its gateway instance, whether EC2 or On-premises, Cache will get filled up fast if not properly configured, For large number of EC2 instances EFS scales better. So, bottom line is File Storage gateway is for legacy applications and you have to add cost of large gateway instances before comparing it to same quantity of EFS storage. https://www.reddit.com/r/aws/comments/82pyop/storage_gateway_vs_efs/

NEW QUESTION 12
A large company experienced a drastic increase in its monthly AWS spend. This is after Developers accidentally launched Amazon EC2 instances in unexpected regions. The company has established practices around least privileges for Developers and controls access to on-premises resources using Active Directory groups. The company now wants to control costs by restricting the level of access that Developers have to the AWS Management Console without impacting their productivity. The company would also like to allow Developers to launch Amazon EC2 in only one region, without limiting access to other services in any region.
How can this company achieve these new security requirements while minimizing the administrative burden on the Operations team?

• A. Set up SAML-based authentication tied to an IAM role that has an AdministrativeAccess managed policy attached to i
• B. Attach a customer managed policy that denies access to Amazon EC2 in each region except for the one required.
• C. Create an IAM user for each Developer and add them to the developer IAM group that has the PowerUserAccess managed policy attached to i
• D. Attach a customer managed policy that allows the Developers access to Amazon EC2 only in the required region.
• E. Set up SAML-based authentication tied to an IAM role that has a PowerUserAccess managed policy and a customer managed policy that deny all the Developers access to any AWS services except AWS Service Catalo
• F. Within AWS Service Catalog, create a product containing only the EC2 resources in the approved region.
• G. Set up SAML-based authentication tied to an IAM role that has the PowerUserAccess managed policy attached to i
• H. Attach a customer managed policy that denies access to Amazon EC2 in each region except for the one required.

Answer: D

Explanation:
The tricks here are: - SAML for AD federation and authentication - PowerUserAccess vs AdministrativeAccess. (PowerUSer has less privilege, which is the required once for developers). Admin, has more rights. The description of "PowerUser access" given by AWS is “Provides full access to AWS services and resources, but does not allow management of Users and groups.”
