The correct answer is that the tablet and printer will connect but only at Bluetooth 2.1 capabilities. This is because Bluetooth is designed with full backward compatibility across versions, meaning a Bluetooth 5.0 host can discover, pair, and communicate with a legacy Bluetooth 2.1 peripheral, but the entire link must negotiate down to the lowest common denominator—the older device’s supported feature set. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding that backward compatibility does not mean the newer device’s enhanced range, speed, or data throughput will be available; instead, the connection is limited by the older version’s specifications. A common trap is assuming the devices won’t connect at all or that the newer device will somehow “upgrade” the older one. To remember this, think of it like a highway: a sports car (Bluetooth 5.0) can drive on an old dirt road (Bluetooth 2.1), but it must slow down to the road’s speed limit.
220-1101 Mobile Device Connection Methods Practice Question
This 220-1201 practice question tests your understanding of mobile device connection methods. 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 deploying a fleet of tablets for field workers who need to print invoices on a Bluetooth printer. The tablets are Android-based and support Bluetooth 5.0. The printer is an older model supporting Bluetooth 2.1. Which of the following is true about the compatibility between these devices?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The tablet and printer will connect but only at Bluetooth 2.1 capabilities.
Bluetooth is backward compatible, so a Bluetooth 5.0 device can connect to a Bluetooth 2.1 device, but it will operate at the lower version's capabilities. This tests knowledge of Bluetooth version compatibility and that features like range and speed are limited by the older device.
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.
✗
The tablet will not be able to pair with the printer due to version mismatch.
Why it's wrong here
Bluetooth is backward compatible; pairing is possible between different versions.
✗
The connection will operate at Bluetooth 5.0 speeds and range.
Why it's wrong here
The connection operates at the lowest common version, so Bluetooth 2.1's limitations apply.
✓
The tablet and printer will connect but only at Bluetooth 2.1 capabilities.
Why this is correct
Backward compatibility ensures they connect, but the older device's version dictates the connection parameters.
Related concept
Static NAT maps one inside address to one outside address.
✗
The printer must be upgraded to Bluetooth 4.0 to work with the tablet.
Why it's wrong here
No upgrade is needed; Bluetooth 2.1 devices work with newer versions.
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.
