220-1201 Mobile Device Accessories Practice Question
This 220-1201 practice question tests your understanding of mobile device accessories. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 setting up a new tablet for a field worker who needs to capture signatures from customers. The tablet has a standard USB-C port. Which accessory is most appropriate for this task?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A capacitive stylus with a fine tip.
A stylus with a fine tip is ideal for capturing signatures accurately on a touchscreen. Capacitive styluses are common for this purpose. The correct answer is a capacitive stylus, as it provides precision.
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.
✗
A Bluetooth keyboard for typing notes.
Why it's wrong here
A keyboard is not suitable for signature capture; it is for text input.
✓
A capacitive stylus with a fine tip.
Why this is correct
This is correct; a stylus provides the precision needed for signatures.
Related concept
Static NAT maps one inside address to one outside address.
✗
A USB-C to HDMI adapter for external display.
Why it's wrong here
An HDMI adapter is for video output, not input; it does not help with signatures.
✗
A screen protector to prevent scratches.
Why it's wrong here
A screen protector protects the screen but does not aid in signature capture.
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.
Trap categories for this question
Command / output trap
An HDMI adapter is for video output, not input; it does not help with signatures.
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.
