- A
Install a door alarm on the office entrance
Why wrong: An office door alarm does not secure the rack itself; servers could still be accessed if the office is entered.
- B
Use rack-mount locks on each server chassis
Rack-mount locks physically prevent the server from being slid out or tampered with, directly securing the hardware.
- C
Enable BitLocker on all server drives
Why wrong: BitLocker protects data if a drive is removed, but does not prevent physical access to the server itself.
- D
Configure a strong BIOS password
Why wrong: A BIOS password prevents unauthorized booting but does not secure the physical server chassis from being opened or removed.
Question 439 of 750
Rack-Mount Locks: Securing Servers in Shared Spaces
This 220-1202 practice question tests your understanding of physical security controls. 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 technician is configuring a new server rack in a shared office space. Which physical security measure should be applied to prevent unauthorized physical access to the servers?
Quick Answer
The answer is to use rack-mount locks on each server chassis. This physical security measure directly prevents unauthorized removal or tampering with individual servers by securing the chassis within the rack, which is essential in a shared office space where multiple people have physical access. On the CompTIA A+ Core 2 220-1202 exam, this question tests your understanding of physical security controls for multi-tenant environments, often contrasting rack-mount locks with broader solutions like door locks or cable locks. A common trap is choosing a general lock for the rack door, but the key distinction is that rack-mount locks secure each server independently, not just the enclosure. For a memory tip, think “chassis lock, not just door lock”—each server needs its own lock to stop someone from sliding it out, even if the rack door is open.
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
✓
Use rack-mount locks on each server chassis
Option B is correct because rack-mount locks provide a direct physical barrier that prevents unauthorized individuals from opening the server chassis and accessing internal components, such as hard drives, memory, or cables. In a shared office space, this is the most effective measure to deter tampering, theft, or accidental damage at the rack level.
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.
- ✗
Install a door alarm on the office entrance
Why it's wrong here
An office door alarm does not secure the rack itself; servers could still be accessed if the office is entered.
- ✓
Use rack-mount locks on each server chassis
Why this is correct
Rack-mount locks physically prevent the server from being slid out or tampered with, directly securing the hardware.
Related concept

- ✗
Enable BitLocker on all server drives
Why it's wrong here
BitLocker protects data if a drive is removed, but does not prevent physical access to the server itself.
- ✗
Configure a strong BIOS password
Why it's wrong here
A BIOS password prevents unauthorized booting but does not secure the physical server chassis from being opened or removed.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse logical security controls (like BitLocker or BIOS passwords) with physical security controls, failing to recognize that only a physical barrier like a lock prevents direct hardware access.
Detailed technical explanation
How to think about this question
Rack-mount locks are typically integrated into the server chassis or rack rails and use a key or combination to secure the chassis in the rack. In a shared office environment, this prevents casual tampering, such as someone pressing the reset button, disconnecting cables, or removing drives, which could cause data loss or service disruption. A real-world scenario is a co-working space where multiple tenants share a rack; without locks, any tenant could accidentally or maliciously access another tenant's server.
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 practitioner preparing for the 220-1202 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.
