List of questions
Question 211

A company is creating an account strategy so that they can begin using AWS. The Security team will provide each team with the permissions they need to follow the principle or least privileged access. Teams would like to keep their resources isolated from other groups, and the Finance team would like each team’s resource usage separated for billing purposes. Which account creation process meets these requirements and allows for changes?
Explanation:
By creating individual IAM users for people accessing your account, you can give each IAM user a unique set of security credentials. You can also grant different permissions to each IAM user. If necessary, you can change or revoke an IAM user's permissions anytime. (If you give out your root user credentials, it can be difficult to revoke them, and it is impossible to restrict their permissions.)

Question 212

Which of the following statements is correct about the number of security groups and rules applicable for an EC2-Classic instance and an EC2-VPC network interface?
Explanation:
A security group acts as a virtual firewall that controls the traffic for one or more instances. When you launch an instance, you associate one or more security groups with the instance. You add rules to each security group that allow traffic to or from its associated instances. If you're using EC2-Classic, you must use security groups created specifically for EC2-Classic. In EC2-Classic, you can associate an instance with up to 500 security groups and add up to 100 rules to a security group. If you're using EC2-VPC, you must use security groups created specifically for your VPC. In EC2-VPC, you can associate a network interface with up to 5 security groups and add up to 50 rules to a security group.

Question 213

An organization is setting up RDS for their applications. The organization wants to secure RDS access with VPC. Which of the following options is not required while designing the RDS with VPC?
Explanation:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the user to launch AWS resources, such as RDS into a virtual network that the user has defined. Subnets are segments of a VPC's IP address range that the user can designate to a group of VPC resources based on security and operational needs. A DB subnet group is a collection of subnets (generally private) that the user can create in a VPC and assign to the RDS DB instances. A DB subnet group allows the user to specify a particular VPC when creating the DB instances.
Each DB subnet group should have subnets in at least two Availability Zones in a given region. If the RDS instance is required to be accessible from the internet the organization must enable the VPC attributes, DNS hostnames and DNS resolution. For each RDS DB instance that the user runs in a VPC, he should reserve at least one address in each subnet in the DB subnet group for use by Amazon RDS for recovery actions.

Question 214

An organization is planning to use NoSQL DB for its scalable data needs. The organization wants to host an application securely in AWS VPC. What action can be recommended to the organization?
Explanation:
The Amazon Virtual Private Cloud (Amazon VPC) allows the user to define a virtual networking environment in a private, isolated section of the Amazon Web Services (AWS) cloud. The user has complete control over the virtual networking environment. Currently VPC does not support DynamoDB. Thus, if the user wants to implement VPC, he has to setup his own NoSQL DB within the VPC.

Question 215

MapMySite is setting up a web application in the AWS VPC. The organization has decided to use an AWS RDS instead of using its own DB instance for HA and DR requirements. The organization also wants to secure RDS access. How should the web application be setup with RDS?
Explanation:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the user to launch AWS resources, such as RDS into a virtual network that the user has defined. Subnets are segments of a VPC's IP address range that the user can designate to a group of VPC resources based on the security and operational needs. A DB subnet group is a collection of subnets (generally private) that a user can create in a VPC and assign to the RDS DB instances. A DB subnet group allows the user to specify a particular VPC when creating the DB instances. Each DB subnet group should have subnets in at least two Availability Zones in a given region.

Question 216

A company operates an on-premises software-as-a-service (SaaS) solution that ingests several files daily. The company provides multiple public SFTP endpoints to its customers to facilitate the file transfers. The customers add the SFTP endpoint IP addresses to their firewall allow list for outbound traffic. Changes to the SFTP endpoint IP addresses are not permitted. The company wants to migrate the SaaS solution to AWS and decrease the operational overhead of the file transfer service. Which solution meets these requirements?
Question 217

A fitness tracking company serves users around the world, with its primary markets in North America and Asia. The company needs to design an infrastructure for its read-heavy user authorization application with the following requirements:
Be resilient to problem with the application in any Region.
Write to a database in a single Region.
Read from multiple Regions.
Support resiliency across application tiers in each Region.
Support the relational database semantics reflected in the application.
Which combination of steps should a solutions architect take? (Choose two.)
Question 218

An organization is planning to setup a management network on the AWS VPC. The organization is trying to secure the webserver on a single VPC instance such that it allows the internet traffic as well as the back-end management traffic. The organization wants to make so that the back end management network interface can receive the SSH traffic only from a selected IP range, while the internet facing webserver will have an IP address which can receive traffic from all the internet IPs.
How can the organization achieve this by running web server on a single instance?
Explanation:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the user to launch AWS resources into a virtual network that the user has defined. An Elastic Network Interface (ENI) is a virtual network interface that the user can attach to an instance in a VPC. The user can create a management network using two separate network interfaces. For the present scenario it is required that the secondary network interface on the instance handles the public facing traffic and the primary network interface handles the back-end management traffic and it is connected to a separate subnet in the VPC that has more restrictive access controls. The public facing interface, which may or may not be behind a load balancer, has an associated security group to allow access to the server from the internet while the private facing interface has an associated security group allowing SSH access only from an allowed range of IP addresses either within the VPC or from the internet, a private subnet within the VPC or a virtual private gateway.

Question 219

A company has an application behind a load balancer with enough Amazon EC2 instances to satisfy peak demand. Scripts and third-party deployment solutions are used to configure EC2 instances when demand increases or an instance fails. The team must periodically evaluate the utilization of the instance types to ensure that the correct sizes are deployed. How can this workload be optimized to meet these requirements?
Question 220

A company has multiple AWS accounts and manages these accounts which AWS Organizations. A developer was given IAM user credentials to access AWS resources. The developer should have readonly access to all Amazon S3 buckets in the account. However, when the developer tries to access the S3 buckets from the console, they receive an access denied error message with no bucket listed. A solution architect reviews the permissions and finds that the developer’s IAM user is listed as having read-only access to all S3 buckets in the account. Which additional steps should the solutions architect take to troubleshoot the issue? (Choose two.)
