Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) Sample Questions (Q469-Q474):

NEW QUESTION # 469
A company website contains a web tier and a database tier on AWS. The web tier consists of Amazon EC2 instances that run in an Auto Scaling group across two Availability Zones. The database tier runs on an Amazon ROS for MySQL Multi-AZ DB instance. The database subnet network ACLs are restricted to only the web subnets that need access to the database. The web subnets use the default network ACL with the default rules.
The company's operations team has added a third subnet to the Auto Scaling group configuration. After an Auto Scaling event occurs, some users report that they intermittently receive an error message. The error message states that the server cannot connect to the database. The operations team has confirmed that the route tables are correct and that the required ports are open on all security groups.
Which combination of actions should a SysOps administrator take so that the web servers can communicate with the DB instance? (Select TWO.)

  • A. On the network ACLs for the database subnets, create an outbound Allow rule of type TCP with the ephemeral port range and the destination as the third web subnet.
  • B. On the network ACLs for the database subnets, create an outbound Allow rule of type MySQL/Aurora (3306). Specify the destination as the third web subnet.
  • C. On the default ACL, create outbound Allow rules of type MySQL/Aurora (3306). Specify the destinations as the database subnets.
  • D. On the default ACL. create inbound Allow rules of type TCP with the ephemeral port range and the source as the database subnets.
  • E. On the network ACLs for the database subnets, create an inbound Allow rule of type MySQL/Aurora (3306). Specify the source as the third web subnet.

Answer: A,E

Explanation:
To ensure that the new web subnet can communicate with the database instance, follow these steps:
* Create an Inbound Allow Rule for MySQL/Aurora (3306):
* On the network ACL for the database subnets, add an inbound allow rule to permit traffic from the third web subnet on port 3306 (MySQL/Aurora).
Reference: Network ACLs
Create an Outbound Allow Rule for Ephemeral Ports:
On the network ACL for the database subnets, add an outbound allow rule to permit traffic to the third web subnet on the ephemeral port range (1024-65535).
Reference: Ephemeral Ports
These changes will ensure that the new subnet can communicate with the database, resolving the connectivity issues.


NEW QUESTION # 470
A company runs its entire suite of applications on Amazon EC2 instances. The company plans to move the applications to containers and AWS Fargate. Within 6 months, the company plans to retire its EC2 instances and use only Fargate. The company has been able to estimate its future Fargate costs.
A SysOps administrator needs to choose a purchasing option to help the company minimize costs. The SysOps administrator must maximize any discounts that are available and must ensure that there are no unused reservations.
Which purchasing option will meet these requirements?

  • A. Compute Savings Plans for 1 year with the No Upfront payment option
  • B. Compute Savings Plans for 1 year with the Partial Upfront payment option
  • C. EC2 Reserved Instances for 1 year with the Partial Upfront payment option
  • D. EC2 Instance Savings Plans for 1 year with the All Upfront payment option

Answer: A

Explanation:
To minimize costs while moving from EC2 instances to AWS Fargate, Compute Savings Plans are the most flexible and cost-effective option. Compute Savings Plans apply to a variety of compute services including AWS Fargate, Amazon EC2, and AWS Lambda, allowing for greater flexibility in managing costs as the company transitions to using only Fargate.
* Compute Savings Plans:
* Savings Plans provide significant savings over On-Demand pricing, up to 66% savings.
* Compute Savings Plans offer the flexibility to move across instance types, AWS Regions, and operating systems.
* Payment Options:
* The No Upfront payment option provides the most flexibility and avoids large upfront capital expenditures.
* The Partial Upfront payment option offers more savings but requires an initial payment.
* 1-Year Term:
* A 1-year term is suitable for the company's 6-month transition period, allowing for cost savings without a long-term commitment.

NEW QUESTION # 471
A company uses AWS Organizations. A SysOps administrator wants to use AWS Compute Optimizer and AWS tag policies in the management account to govern all member accounts in the billing family.

  • A. Consolidated billing has not been enabled.
  • B. All features have not been enabled in the organization.
  • C. The member accounts have not manually enabled trusted access for Compute Optimizer.
  • D. The member accounts do not have tags enabled for cost allocation.

Answer: B

Enable All Features in AWS Organizations:
Open the AWS Organizations console at AWS Organizations Console.
Navigate to Settings and ensure that All features are enabled.
Verify and Enable Trusted Access:
Ensure that trusted access is enabled for AWS Compute Optimizer and other relevant services.
This allows the management account to access and manage resources in member accounts.
Use AWS Compute Optimizer and Tag Policies:
Once all features are enabled, configure and manage AWS Compute Optimizer and tag policies from the management account.

NEW QUESTION # 473
A company is managing multiple AWS accounts in AWS Organizations. The company is reviewing internal security of its AWS environment. The company's security administrator has their own AWS account and wants to review the VPC configuration of developer AWS accounts.
Which solution will meet these requirements in the MOST secure manner?

  • A. Create an IAM policy in each developer account that has administrator access to all Amazon EC2 actions, including VPC actions. Assign the policy to an IAMuser. Share the user credentials with the security administrator.
  • B. Create an IAM policy in each developer account that has read-only access related to VPC resources Assign the policy to a cross-account IAM role Ask the security administrator to assume the role from their account.
  • C. Create an IAM policy in each developer account that has administrator access related to VPC resources.
    Assign the policy to a cross-account IAM role. Ask the security administrator to assume the role from their account.
  • D. Create an IAM policy in each developer account that has read-only access related to VPC resources Assign the policy to an IAM user. Share the user credentials with the security administrator.

Answer: B

Explanation:
To securely allow a security administrator to review the VPC configuration of developer AWS accounts, the best approach is to create a cross-account IAM role with read-only access to VPC resources. Here's how to do it:
Create IAM Policy:
In each developer account, create an IAM policy with read-only permissions "Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"ec2:DescribeVpcs",
"ec2:DescribeSubnets",
"ec2:DescribeRouteTables",
"ec2:DescribeSecurityGroups",
"ec2:DescribeNetworkAcls"
],
"Resource": "*"
}
]
}
Create Cross-Account IAM Role:
Create an IAM role in each developer account, assign the read-only policy to the role, and allow the security administrator's account to assume the role.
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::security-admin-account-id:root"
},
"Action": "sts:AssumeRole"
}
]
}
Assume the Role:
The security administrator can assume the role from their own account using the AWS Management Console or AWS CLI.
aws sts assume-role --role-arn arn:aws:iam::developer-account-id:role/role-name --role-session-name security- admin-session Review VPC Configuration:
After assuming the role, the security administrator can review the VPC configuration using the AWS Management Console or AWS CLI with the temporary credentials.
