The answer is to isolate backup traffic on a separate VLAN to reduce network congestion. This is the correct course of action because placing the backup server on the same network segment as production traffic creates bandwidth contention, especially during peak hours, leading to backup timeouts and failures. The technical concept at play is VLAN isolation, which logically segments network traffic to prevent backup network congestion from interfering with production operations, ensuring dedicated bandwidth for data transfers. On the CompTIA Project+ PK0-005 exam, this scenario tests your ability to apply network segmentation as a project management solution to performance issues, often appearing as a distractor against options like upgrading hardware or adjusting schedules. A common trap is choosing to increase bandwidth across the entire network, which is costly and doesn’t address the root cause of traffic competition. Memory tip: think “VLAN for VLANquish congestion”—isolating backup traffic logically separates the noise from the signal.
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. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 company is implementing a new backup solution for its mixed environment of legacy and modern servers. The backup server is connected to the same network segment as production traffic. During initial testing, some backups fail intermittently, especially during peak hours. The backup logs show timeouts. The project manager is asked to identify the most likely cause and recommend a solution. Which of the following is the best course of action?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Isolate backup traffic on a separate VLAN to reduce network congestion.
The backup server is on the same network segment as production traffic, causing congestion during peak hours. Backup timeouts indicate that the backup traffic is competing with production traffic for bandwidth, leading to packet loss or delays. Isolating backup traffic on a separate VLAN reduces network congestion by logically separating the traffic, ensuring dedicated bandwidth for backups and preventing interference with production operations.
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.
✗
Upgrade the backup software to the latest version.
Why it's wrong here
While a software update might help, the intermittent nature during peak hours points to network congestion, not software bugs.
✓
Isolate backup traffic on a separate VLAN to reduce network congestion.
Why this is correct
Separating backup traffic onto its own VLAN reduces contention with production traffic, resolving timeouts.
Clue confirmation
The clue words "best", "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the backup window to allow more time.
Why it's wrong here
Increasing the window does not reduce network congestion; backups may still fail during peak usage.
✗
Replace legacy servers with modern hardware.
Why it's wrong here
Replacing servers is costly and does not address the network congestion issue.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume timeouts are caused by software or hardware failures, rather than recognizing the classic network congestion symptom where backup traffic competes with production traffic on the same subnet.
Detailed technical explanation
How to think about this question
VLANs operate at Layer 2 of the OSI model, logically segmenting broadcast domains to reduce collision domains and improve network efficiency. By placing backup traffic on a separate VLAN, you can apply QoS policies (e.g., IEEE 802.1p) to prioritize backup traffic or use dedicated bandwidth, preventing timeouts caused by TCP retransmissions due to packet drops. In real-world scenarios, backup solutions like Veeam or NetBackup often recommend dedicated backup networks or VLANs to avoid performance degradation during peak hours.

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 help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
