PK0-005 Practice Question: A project has a dependency that requires the…
A project has a dependency that requires the foundation to be poured before the walls can be erected. This is an example of which type of dependency?
⚠ Common exam trap
The trap is confusing mandatory (hard logic) dependencies with discretionary (soft logic) ones — candidates may think any logical sequence is discretionary, but physical or contractual necessities are mandatory.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Mandatory dependency
A mandatory dependency is one that is contractually or legally required, often due to hard logic or regulatory constraints. Pouring the foundation before erecting walls is a physical necessity — you cannot build walls without a foundation — making it a mandatory dependency. This is also known as a hard logic dependency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Mandatory dependency
Why this is correct
Pouring foundations before erecting walls is dictated by physical construction logic, not preference or resource availability. Mandatory dependencies are those inherent to the nature of the work itself, so this sequence cannot be reordered or fast-tracked.
- ✗
Discretionary dependency
Why it's wrong here
A discretionary dependency is one chosen by the team rather than required by the work itself. It is tempting because some sequencing is optional, but pouring foundations before walls is physically mandatory, making it a mandatory dependency instead.
- ✗
External dependency
Why it's wrong here
An external dependency involves a party outside the project team, such as a supplier or regulator. It is tempting because site work can involve external contractors, but the foundation-to-wall sequence is an internal logical relationship, not an external one.
- ✗
Resource constraint
Why it's wrong here
A resource constraint concerns limited availability of people, equipment, or materials, not a logical order between activities. It is tempting because pouring foundations does consume resources, but the dependency described is a mandatory sequence, not a capacity limitation.
