The answer is long lead times for hardware procurement and unforeseen dependencies between tasks. Hardware procurement delays are common in IT infrastructure because specialized equipment like servers, switches, or cabling often has extended manufacturing or shipping timelines, and any ordering mistake or supply chain disruption can stall the entire project. Unforeseen dependencies between tasks cause cascading delays when hidden interconnections—such as a firewall rule change needed before a network upgrade—are not mapped in the schedule, a critical risk in tightly coupled infrastructure environments. On the CompTIA Project+ PK0-005 exam, this tests your ability to identify procurement risks and dependency mapping failures, with a common trap being to confuse “unforeseen dependencies” with simple resource conflicts. Remember the mnemonic “HARD” for Hardware and Hidden Dependencies as the two primary delay drivers in IT infrastructure projects.
PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
This PK0-005 practice question tests your understanding of basics of it infrastructure and it project management. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 common causes of project delays in IT infrastructure projects? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Unforeseen dependencies between tasks
Unforeseen dependencies between tasks (B) are a common cause of delays because IT infrastructure projects often involve complex interconnections—for example, a network upgrade may depend on a prior firewall rule change or a storage array reconfiguration. When these hidden dependencies are not mapped in the project schedule, a delay in one task cascades to dependent tasks, pushing the entire timeline. This is especially critical in infrastructure where hardware, software, and configuration tasks are tightly coupled.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Successful integration testing
Why it's wrong here
Successful testing actually prevents delays.
✓
Unforeseen dependencies between tasks
Why this is correct
Hidden dependencies can cause cascading delays.
Related concept
Read the scenario before looking for a memorised answer.
✗
Overestimating resource capacity
Why it's wrong here
Overestimation leads to buffer, not delays.
✓
Long lead times for hardware procurement
Why this is correct
Hardware delivery can take weeks or months, causing delays.
Related concept

✗
Frequent status meetings
Why it's wrong here
Meetings can be managed; they are not a primary cause of delays.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between positive project events (like successful testing) and actual delay causes, so candidates mistakenly pick 'successful integration testing' because they confuse a good outcome with a project risk.
Detailed technical explanation
How to think about this question
In IT infrastructure projects, dependencies often arise from network protocols like BGP convergence times or DNS propagation delays—for instance, a router upgrade may require a prior BGP session teardown and re-establishment, which can take minutes to hours. Real-world scenarios include cloud migration where a database must be replicated before the application layer can be cut over; missing this dependency can cause extended downtime. Understanding the critical path method (CPM) and dependency types (FS, SS, FF, SF) is essential to identify such hidden links early.
KKey Concepts to Remember

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
