#10. Which of the following AWS Cloud services can be used to run a customer-managed relational database?

The majority of SAP solutions use a customer-managed model on Amazon EC2. Installation, configuration, administration, and backup and recovery of the database are done by either the customer or a partner.

#12. Which statement best describes Elastic Load Balancing?

Elastic Load Balancing automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. It can handle the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones. Elastic Load Balancing offers three types of load balancers that all feature the high availability, automatic scaling, and robust security necessary to make your applications fault tolerant.

#15. Which of the following AWS services can be used to serve large amounts of online video content with the lowest possible latency?

#16. Which one of this is not an Infrastructure Service?

Container Services: Services in this category typically run on separate
Amazon EC2 or other infrastructure instances, but sometimes you don’t
manage the operating system or the platform layer. AWS provides a managed service for these application “containers”. You are responsible
for setting up and managing network controls, such as firewall rules, and
for managing platform-level identity and access management separately
from IAM. Examples of container services include Amazon Relational
Database Services (Amazon RDS), Amazon Elastic Map Reduce (Amazon
EMR) and AWS Elastic Beanstalk

#17. Which one of this is not an Abstracted Service?

Abstracted Services: This category includes high-level storage,
database, and messaging services, such as Amazon Simple Storage Service
(Amazon S3), Amazon Glacier, Amazon DynamoDB, Amazon Simple
Queuing Service (Amazon SQS), and Amazon Simple Email Service
(Amazon SES). These services abstract the platform or management layer
on which you can build and operate cloud applications. You access the
endpoints of these abstracted services using AWS APIs, and AWS
manages the underlying service components or the operating system on
which they reside. You share the underlying infrastructure, and abstracted
services provide a multi- tenant platform which isolates your data in a
secure fashion and provides for powerful integration with IAM.

#18. which one is no a Trusted Advisor recommendation:

#19. Which one is not a good practice?

Create separate AWS accounts for each autonomous
part of the organization. You can assign permissions
and policies under each account.

#20. Best practices: 3 different AWS customers in the same organization and with the same duties should…

For example, let’s assume that IAM user John is responsible for backups within an organization, and needs to access objects in the Amazon S3 bucket called Archives. You can give John permissions directly so he can access theArchives bucket. But then your organization places Sally and Betty on the same team as John. While you can assign user permissions individually to John, Sally, and Betty to give them access to the Archives bucket, assigning the permissions to a group and placing John, Sally, and Betty in that group will be easier to manage and maintain. If additional users require the same access, you can give it to them by adding them to the group. When a user no longer needs access to a resource, you can remove them from the groups that provide access to that resource.

#21. Web servers running on Amazon EC2 access a legacy application running in a corporate data center. What term would describe this model?

Enterprise environments are often a mix of cloud, on-premises data centers, and edge locations. Hybrid cloud architectures help organizations integrate their on-premises and cloud operations to support a broad spectrum of use cases using a common set of cloud services, tools, and APIs across on-premises and cloud environments.
