The combination of solutions that will meet the requirements are:

A. Create a local individual break glass IAM user for the security team. Create a trail in AWS CloudTrail that has Amazon CloudWatch Logs turned on. Use Amazon EventBridge to monitor local user activities. This is a valid solution because it allows the security team to access the workload AWS account and instances using a local IAM user that does not depend on SAML federation.It also enables logging and monitoring of the break glass user activities using AWS CloudTrail, Amazon CloudWatch Logs, and Amazon EventBridge123.

E. Configure AWS Systems Manager Session Manager for Amazon EC2. Configure an AWS CloudTrail filter based on Session Manager. Send the results to an Amazon Simple Notification Service (Amazon SNS) topic. This is a valid solution because it allows the security team to access the workload instances without opening any inbound ports or managing SSH keys or bastion hosts.It also enables logging and notification of the breakglass user activities using AWS CloudTrail, Session Manager, and Amazon SNS456.

The other options are incorrect because:

B.Creating a break glass EC2 key pair for the AWS account and providing it to the security team is not a valid solution, because it requires opening inbound ports on the instances and managing SSH keys, which increases the security risk and complexity7.

C.Creating a break glass IAM role for the account and allowing security team members to perform the AssumeRoleWithSAML operation is not a valid solution, because it still dependson SAML federation, which might not work in case of SAML errors8.

D.Creating a local individual break glass IAM user on the operating system level of each workload instance and configuring unrestricted security groups on theinstances to grant access to the break glass IAM users is not a valid solution,because it requires opening inbound ports on the instances and managing multiple local users, which increases the security risk and complexity9.
