The answer is redundant network paths, as they are the infrastructure component that must be prioritized to meet both high availability and low latency requirements in a data center build. Redundant network paths ensure that if one link or switch fails, traffic can immediately fail over to an alternate path, eliminating a single point of failure and maintaining uptime. They also reduce latency by enabling load balancing across multiple links, which is critical for real-time applications that cannot tolerate delay. On the CompTIA Project+ PK0-005 exam, this concept tests your understanding of how network design directly supports availability and performance objectives—a common trap is confusing redundancy with simple backup hardware, but the key is that paths, not just devices, must be duplicated. Remember the memory tip: "Paths for uptime, paths for speed—redundant links are all you need."
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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 planning a new data center build. The organization requires high availability and low latency for critical applications. Which infrastructure component should be prioritized to meet these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Redundant network paths
Redundant network paths ensure that if one link or switch fails, traffic can immediately fail over to an alternate path, providing high availability. They also reduce latency by enabling load balancing across multiple links, which is critical for real-time applications. This directly addresses the requirement for both high availability and low latency in a data center build.
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.
✗
Additional storage arrays
Why it's wrong here
Storage arrays improve capacity and redundancy but do not directly address network latency.
✗
Additional firewall appliances
Why it's wrong here
More firewalls can introduce processing delays and increase latency.
✓
Redundant network paths
Why this is correct
Redundant network paths ensure high availability and can reduce latency through load balancing.

✗
Virtualization licenses
Why it's wrong here
Virtualization licenses help with resource pooling but do not impact network performance directly.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that adding more hardware (like storage or firewalls) directly improves availability and latency, when in fact network path redundancy is the foundational component for both in a data center context.
Detailed technical explanation
How to think about this question
Redundant network paths are typically implemented using technologies like Spanning Tree Protocol (STP) for loop prevention or, more commonly in modern data centers, Layer 2 multipathing (e.g., TRILL, SPB) or Layer 3 equal-cost multipath (ECMP) routing. ECMP allows multiple active paths with equal cost, distributing traffic and reducing latency while providing automatic failover via routing protocols like OSPF or BGP. In a real-world scenario, a data center using redundant paths with ECMP can maintain sub-millisecond failover times, whereas a single-path design would cause application timeouts during a link failure.

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.
