Resource Management

Correct Answer: Evaluate the impact of the team member's absence on the critical task and identify potential replacements or temporary reassignments.

The project manager should evaluate the impact of the team member's absence on the critical task and identify potential replacements or temporary reassignments. This approach allows the project manager to proactively address any potential delays and keep the project on schedule. By assessing the situation and reallocating resources as necessary, the project manager can mitigate risks associated with the team member's unavailability and ensure that critical tasks are completed on time.

Correct Answer: Use AWS IAM Identity Center (AWS SSO) integrated with AWS Organizations, connected to the corporate identity provider, and assign a ReadOnlyAccess permission set to the audit group across all member accounts.

AWS IAM Identity Center provides centralized workforce identity and permission management across all accounts in an AWS Organization. By integrating it with the corporate IdP, you enable auditors to authenticate via SSO and assume roles with read-only permissions without creating IAM users in each account. Permission sets (e.g., AWS managed ReadOnlyAccess) can be assigned to the audit group for all member accounts, minimizing operational overhead, reducing risk from long-lived credentials, and ensuring consistent least-privilege access. Alternatives like per-user IAM policies do not scale, using AWS Organizations with a delegated admin does not itself grant human read-only access, generic federation without Identity Center or a cross-account role framework is incomplete, and sharing root credentials is unsafe and violates best practices.

Correct Answer: Resource Leveling

The best strategy to resolve the problem of over-allocation of scarce resources in a construction project is Resource Leveling. Resource Leveling involves adjusting the project schedule to balance the demand for resources with the available supply. It's used to alleviate problems caused by resources being over or under-used, ensuring that work is evenly distributed and that no resources are over-allocated. Fast Tracking, on the other hand, is a schedule compression technique that involves performing more tasks in parallel which may not solve the resource scarcity problem. Resource Smoothing is a similar approach to Resource Leveling, but it only adjusts the project schedule within the existing total float and hence, will not be as efficient as Resource Leveling in case of resource scarcity. Crashing, though is another schedule compression technique, it involves adding additional resources to tasks to finish them quickly, which can presumably not fix the problem since the resources are already scarce.
