The answer is expert judgment, data analysis, and meetings. These are the three primary tools and techniques for the Plan Schedule Management process, as defined in the PMBOK Guide. While the Critical Path Method and leads and lags are indeed schedule development techniques, they are applied later in the Schedule Management process, not during the initial planning of how the schedule will be managed. On the CAPM exam, this question tests your ability to distinguish between the tools used to create the schedule management plan and the tools used to develop the actual schedule model. A common trap is confusing the techniques for developing the schedule (like critical path or rolling wave planning) with the high-level planning techniques for the process itself. Remember the mnemonic "E-DAM" for Plan Schedule Management: Expert judgment, Data analysis, And Meetings.
CAPM Predictive Plan-Based Methodologies Practice Question
This CAPM practice question tests your understanding of predictive plan-based methodologies. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are tools and techniques used in the Plan Schedule Management process?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Leads and lags
Options A and C are correct. Plan Schedule Management uses expert judgment, data analysis, and meetings. Critical path method (A) and leads and lags (C) are part of schedule development, but they are also considered techniques. Rolling wave planning is for scope, not schedule management. Bottom-up estimating is for cost. Decomposition is for scope.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Rolling wave planning
Why it's wrong here
Rolling wave planning is a technique for progressive elaboration of the WBS, not specifically for schedule management.
✗
Bottom-up estimating
Why it's wrong here
Bottom-up estimating is a cost estimating technique, not for schedule management.
✓
Leads and lags
Why this is correct
Leads and lags are adjustments to activity dependencies used during schedule development.
Related concept
Static NAT maps one inside address to one outside address.
✓
Critical path method
Why this is correct
A technique used to identify the longest path in the schedule network; often used in schedule management.
Related concept
Static NAT maps one inside address to one outside address.
✗
Decomposition
Why it's wrong here
Decomposition is used to create the WBS, not for schedule management.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CAPM NAT questions on configuration and troubleshooting.
