SOA-C02 Exam Dumps - AWS Certified SysOps Administrator - Associate (SOA-C02)

Enabling the organizational view in AWS Health will allow the SysOps administrator to consolidate the alerts from each account’s Personal Health Dashboard. It will also provide the administrator with a single view of all the accounts in the organization, allowing them to easily monitor the health of all the accounts in the organization.

Using the interface endpoint, applications in your on-premises data center can easily query S3 buckets over AWS Direct Connect or Site-to-Site VPN. https://aws.amazon.com/blogs/architecture/choosing-your-vpc-endpoint-strategy-for-amazon-s3/

To enforce MFA for API calls using the AWS CLI, the users must use temporary security credentials obtained through the get-session-token command. Here’s how to do it:

Enable MFA for IAM Users:

Ensure that MFA is enabled and properly configured for each IAM user.

Configure IAM Policy for MFA Enforcement:

Attach an IAM policy that denies API calls unless MFA is used. This policy should be attached to all users.

Obtain Temporary Security Credentials Using MFA:

Users need to use the aws sts get-session-token command to obtain temporary credentials. This command requires the MFA token.

sh

Copy code

aws sts get-session-token --serial-number arn:aws:iam::123456789012:mfa/user --token-code 123456

Use Temporary Credentials for API Calls:

After obtaining the temporary credentials, set them as environment variables or configure them in the AWS CLI profile to make API calls.

export AWS_ACCESS_KEY_ID=...

export AWS_SECRET_ACCESS_KEY=...

export AWS_SESSION_TOKEN=...

Step-by-Step Explanation:

Understand the Problem:

Users report that file retrieval from the Amazon EFS file system is slower than normal.

Analyze the Requirements:

Improve the performance of the EFS file system to handle increased usage and file retrieval speed.

Evaluate the Options:

Option A: Configure the file system for Provisioned Throughput.

Provisioned Throughput mode allows you to specify the throughput of your file system independent of the amount of data stored.

This option is suitable for applications with high throughput-to-storage ratio requirements and ensures consistent performance.

Option B: Enable encryption in transit on the file system.

While this enhances security, it does not directly improve performance.

Option C: Identify any unused files in the file system, and remove the unused files.

This may free up some resources but does not address the root cause of slow performance.

Option D: Resize the Amazon EBS volume of each of the EC2 instances.

EFS performance issues are not directly related to the size of EBS volumes attached to EC2 instances.

Select the Best Solution:

Option A: Configuring the file system for Provisioned Throughput ensures consistent performance by allowing you to set the required throughput regardless of the amount of data stored.

Provisioned Throughput Mode

Configuring Provisioned Throughput for Amazon EFS provides a consistent and higher performance level, which is suitable for high throughput requirements.

The policy provided includes two statements:

The first statement explicitly denies the Update:* action on resources with a LogicalResourceId that begins with "Production".

The second statement allows the Update:* action on all resources.

In AWS IAM policy evaluation logic, explicit denies always take precedence over allows. Therefore, the effect of this policy is that users can update all resources in the stack except for those with a logical ID that begins with "Production".

Step-by-Step Explanation:

Understand the Problem:

Ensure all users in the organization have read-level access to a specific S3 bucket.

The data should not be accessible outside the organization.

Analyze the Requirements:

Grant read access to users within the organization.

Prevent access from outside the organization.

Evaluate the Options:

Option A: Specify "*" as the principal and PrincipalOrgId as a condition.

This grants access to all AWS principals but restricts it to those within the specified organization using the PrincipalOrgId condition.

Option B: Specify all account numbers as the principal.

This is impractical for a large organization and requires constant updates if accounts are added or removed.

Option C: Specify PrincipalOrgId as the principal.

The PrincipalOrgId condition must be used within a policy, not as a principal.

Option D: Specify the organization's management account as the principal.

This grants access only to the management account, not to all users within the organization.

Select the Best Solution:

Option A: Using "*" as the principal with the PrincipalOrgId condition ensures all users within the organization have the required access while preventing external access.

Using "*" as the principal with the PrincipalOrgId condition efficiently grants read access to the S3 bucket for all users within the organization.

To centrally manage application logs and retain them for no more than 90 days, you can use the Amazon CloudWatch Logs agent to send logs to a CloudWatch log group and configure the log group's retention period.

Update the Launch Template User Data:

Navigate to the EC2 console.

Select the launch template used by the Auto Scaling group.

Edit the launch template to include the following user data script:

#!/bin/bash

yum update -y

yum install -y awslogs

cat < /etc/awslogs/awslogs.conf

[general]

state_file = /var/lib/awslogs/agent-state

[/var/log/messages]

file = /var/log/messages

log_group_name = /my-log-group

log_stream_name = {instance_id}/messages

datetime_format = %b %d %H:%M:%S

[/var/log/secure]

file = /var/log/secure

log_group_name = /my-log-group

log_stream_name = {instance_id}/secure

datetime_format = %b %d %H:%M:%S

EOF

systemctl start awslogsd

systemctl enable awslogsd

Replace /my-log-group with the name of your CloudWatch log group.

Configure the Log Group Retention Period:

Navigate to the CloudWatch console.

In the navigation pane, choose "Logs".

Select the log group created by the CloudWatch Logs agent.

Click on "Actions" and then "Edit retention settings".

Set the retention period to 90 days.

Verify the Configuration:

Ensure that logs from the EC2 instances are being sent to the CloudWatch log group.

Verify that the log group's retention period is correctly set to 90 days.
