Q

Which of the following is a recommended way to provide programmatic access to AWS resources?

2) Use Access Key ID and Secret Access Key to access AWS resources programmatically
3) Use AWS Multi-Factor Authentication (AWS MFA) to access AWS resources programmatically
4) Create a new IAM user and share the username and password

A

Use Access Key ID and Secret Access Key to access AWS resources programmatically

Programmatic access: Tasks that can be done in an automated way (using such programs), especially as opposed to tasks that have to be done manually (by a person)

WRONG OPTION: “Use IAM user group to access AWS resources programmatically” - An IAM user group is a collection of IAM users. An IAM user group lets you specify permissions for multiple users, which can make it easier to manage the permissions for those users. IAM user group is for managing users and not for programmatic access to AWS resources.

43
Q

AWS Web Application Firewall (WAF) offers protection from common web exploits at which layer?
1) Layer 7

AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to an Amazon API Gateway API, Amazon CloudFront or an Application Load Balancer. HTTP and HTTPS requests are part of the Application layer, which is layer 7.

Incorrect options:

Layer 3 - Layer 3 is the Network layer and this layer decides which physical path data will take when it moves on the network. AWS Shield offers protection at this layer. WAF does not offer protection at this layer.

Layer 4 - Layer 4 is the Transport layer and this layer data transmission occurs using TCP or UDP protocols. AWS Shield offers protection at this layer. WAF does not offer protection at this layer.

2) Raise a support ticket with AWS Support to remove the account
3) The AWS account must be able to operate as a standalone account. Only then it can be removed from AWS organizations
4) The AWS account must not have any Service Control Policies (SCPs) attached to it. Only then it can be removed from AWS organizations

A

The AWS account must be able to operate as a standalone account. Only then it can be removed from AWS organizations.
You can remove an account from your organization only if the account has the information that is required for it to operate as a standalone account. This means it should not rely on the organization for any essential details or resources.
For each account that you want to make standalone, you must accept the AWS Customer Agreement, choose a support plan, provide and verify the required contact information, and provide a current payment method. AWS uses the payment method to charge for any billable (not AWS Free Tier) AWS activity that occurs while the account isn’t attached to an organization.

Incorrect options:
AWS Systems Manager gives you visibility and control of your infrastructure on AWS, it cannot be used to remove an AWS Account from AWS Organizations

6) AWS CloudTrail

A

AWS Config, AWS CloudTrail and Amazon CloudWatch

Being aware of how change affects a system (change management) allows you to plan proactively, and monitoring allows you to quickly identify trends that could lead to capacity issues or SLA breaches.

The three choices allow you to monitor applications and operations. The incorrect options are associated with security or guidance on best practices

Q

A company wants to improve the resiliency of its flagship application so it wants to move from its traditional database system to a managed AWS NoSQL database service to support active-active configuration in both the East and West US AWS regions. The active-active configuration with cross-region support is the prime criteria for any database solution that the company considers. Which service is right for this fit?
1) Amazon Relational Database Service (Amazon RDS) for MYSQL
2) Amazon DynamoDB with global tables
3) Amazon Aurora with multi-master clusters
4) Amazon DynamoDB with DynamoDB Accelerator

A

Amazon DynamoDB with global tables

DynamoDB is NoSQL. DynamoDB global tables replicate data automatically across your choice of AWS Regions

INCORRECT:
DynamoDB Accelerator (DAX) is an in-memory cache that delivers fast read performance for your tables at scale by enabling you to use a fully managed in-memory cache. DAX does not offer active-active cross-Region configuration.
Amazon Aurora (Aurora) is a fully managed relational database engine that’s compatible with MySQL and PostgreSQL. Aurora is not a NoSQL database, so this option is incorrect.

There are three fundamental drivers of cost with AWS: compute, storage, and outbound data transfer. In most cases, there is no charge for inbound data transfer or data transfer between other AWS services within the same region. Outbound data transfer is aggregated across services and then charged at the outbound data transfer rate.

1) The customer needs to manage database backups
2) The performance of AWS managed Amazon Relational Database Service (Amazon RDS) instance is better than a customer-managed database instance
3) There is no need to optimize database instance type and size
4) The customer needs to patch the underlying OS

A

The performance of AWS managed Amazon Relational Database Service (Amazon RDS) instance is better than a customer-managed database instance

Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. Amazon RDS provides a selection of instance types optimized to fit different relational database use cases.
As the RDS instances are optimized for memory, performance, or I/O, therefore the performance of AWS managed Amazon Relational Database Service (Amazon RDS) instance is better than a customer-managed database instance.

Q

A company needs a storage solution for a project wherein the data is accessed less frequently but needs rapid access when required. Which S3 storage class is the MOST cost-effective for the given use-case?
1) Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering)
2) Amazon S3 Standard
3) Amazon S3 Glacier (S3 Glacier)
4) Amazon S3 Standard-Infrequent Access (S3 Standard-IA)

A

Amazon S3 Standard-Infrequent Access (S3 Standard-IA)

S3 Standard-IA offers the high durability, high throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval fee.

S3 Glacier does not support rapid data retrieval, so this option is ruled out.
