CompTIA Updated PK0-005 Exam Questions and Answers by wynter-rose

Infrastructure as a service (IaaS) offers administrators more direct control over operating systems than other cloud service models. IaaS is a type of cloud computing service that provides virtualized computing resources such as servers, storage, network, and operating systems over the internet. IaaS allows users to rent or lease infrastructure resources on demand and pay only for what they use. IaaS gives users more flexibility and control over their infrastructure resources and enables them to configure, manage, and customize their operating systems according to their needs and preferences3

To show dependencies in a schedule, the project manager should use a network diagramming technique—specifically, the Precedence Diagramming Method (PDM). PDM represents activities (nodes) and connects them with relationships (arrows/links) to show task ordering and dependency logic. CompTIA Project+ explicitly includes analyzing and using a project network diagram as a tool, and it also emphasizes understanding dependencies and successor/predecessor relationships (finish-to-start, start-to-start, etc.), which are exactly what PDM models.

The other options don’t match the requirement. Waterfall is a life-cycle methodology, not a dependency diagramming tool. Simulation is typically used for quantitative analysis (e.g., Monte Carlo) rather than directly drawing dependencies. Cost ratio analysis is financial decision support, not schedule dependency mapping.

Therefore, to build a schedule that clearly communicates task order, constraint logic, and critical sequencing, the PM should use precedence diagramming (a form of project network diagram) to visualize and manage dependencies during initiation and early planning.

When a risk trigger is detected, the risk hasn’t yet turned into an issue, but the conditions indicate it may happen. At this stage, the project team should execute the contingency plan that was pre-developed during risk planning. Assigning a risk owner happens earlier in the planning stage, and work-arounds are used only for unplanned risks. Escalation is only needed if the contingency cannot address the risk.
