220-1102 Safety Procedures and Compliance Practice Question
This 220-1202 practice question tests your understanding of safety procedures and compliance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 tasked with disposing of a server that contains multiple SAS hard drives. The company's data destruction policy mandates that drives must be rendered unreadable by any means. Which combination of methods ensures compliance?
Why wrong: A full format does not securely erase data; it can be recovered with specialized tools.
B
Use a degausser on each drive and then shred them.
Degaussing erases magnetic media, and shredding physically destroys the drives, ensuring no data recovery is possible.
C
Overwrite each drive with zeros using a software tool.
Why wrong: While overwriting is effective, it may not be sufficient for all drives (e.g., SSDs with wear leveling) and is not as absolute as physical destruction.
D
Remove the drives and store them in a locked cabinet.
Why wrong: Storing drives does not destroy data; it only delays disposal and does not meet the destruction policy.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a degausser on each drive and then shred them.
For maximum security, physical destruction (shredding) is the most reliable method. Degaussing works for HDDs but not SSDs. Combining shredding with degaussing is redundant but ensures compliance. The correct answer involves physical destruction, as it renders the media completely unusable and data unrecoverable.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Perform a full format on each drive.
Why it's wrong here
A full format does not securely erase data; it can be recovered with specialized tools.
✓
Use a degausser on each drive and then shred them.
Why this is correct
Degaussing erases magnetic media, and shredding physically destroys the drives, ensuring no data recovery is possible.

Why it's wrong here
While overwriting is effective, it may not be sufficient for all drives (e.g., SSDs with wear leveling) and is not as absolute as physical destruction.
✗
Remove the drives and store them in a locked cabinet.
Why it's wrong here
Storing drives does not destroy data; it only delays disposal and does not meet the destruction policy.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
