- A
Purchase redundant SAN controllers to provide failover in case of a controller failure
Why wrong: Redundant controllers address hardware failure within the SAN, not the network link between sites.
- B
Increase the synchronous replication interval to reduce the impact of potential outages
Why wrong: Increasing the interval does not prevent outages and may lead to data loss if the link fails during replication.
- C
Work with the fiber provider to install a second, diverse fiber path between the data centers
A diverse path provides redundancy; if one cable fails, replication continues over the other, maintaining high availability.
- D
Replace synchronous replication with asynchronous replication over the existing WAN connection
Why wrong: Asynchronous replication introduces latency and potential data loss, and relies on the same network link.
Quick Answer
The answer is to work with the fiber provider to install a second, diverse fiber path between the data centers. This is correct because the core risk is a single point of failure in the physical fiber link, which directly threatens the synchronous replication required for the hospital’s EHR system. A diverse fiber path for SAN synchronous replication ensures that if one cable is cut or experiences an outage, replication traffic can instantly fail over to the alternate route, maintaining data consistency and uptime without altering the replication mode. On the CompTIA Project+ PK0-005 exam, this scenario tests your ability to apply risk mitigation strategies to infrastructure dependencies, often disguised as a choice between changing technology (like switching to asynchronous replication) or adding hardware. A common trap is selecting a solution that changes the replication method, which would violate the high-availability requirement. Memory tip: “Diverse path, no wrath”—a second physical route prevents a single cable cut from derailing your go-live.
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. 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.
A project manager is leading a project to upgrade the storage area network (SAN) for a hospital's electronic health records (EHR) system. The current SAN is reaching capacity and has performance issues during peak hours. The new SAN must support high availability with synchronous replication between two data centers located 10 km apart. The project budget is tight, and the timeline is aggressive. During a risk assessment, the project manager identifies that the fiber optic cable between the data centers is owned by a third-party provider and has a history of outages. The project sponsor is concerned about meeting the go-live date and asks the project manager to recommend a course of action to mitigate the risk of cable outages affecting the SAN replication. Which of the following is the BEST course of action?

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
Work with the fiber provider to install a second, diverse fiber path between the data centers
Option C is correct because the risk is specifically a single point of failure in the fiber path between data centers. Installing a second, diverse fiber path eliminates this single point of failure, ensuring synchronous replication can continue even if one cable is cut. This directly addresses the sponsor's concern about go-live delays due to cable outages, without changing the replication mode or adding unnecessary hardware.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse high-availability components (like redundant controllers) with network path redundancy, or incorrectly assume that adjusting replication timing or mode can substitute for fixing the underlying physical connectivity risk.
Detailed technical explanation
How to think about this question
Synchronous replication requires a low-latency, highly available network path because every write must be acknowledged by both sites before completion. A diverse fiber path (often using physically separate routes or different carriers) provides path redundancy, typically implemented via SONET/SDH rings or DWDM with protected circuits. In real-world hospital SAN deployments, a single fiber cut can cause replication to stall, leading to application timeouts and potential data corruption if not properly handled.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- 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 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.
