Compare mobile connection ports and physical plugs for A+
Short answer
At the A+ level the candidate should be able to look at a connector or port and identify which family it belongs to and recommend it for a simple task: charging, data sync, or connecting a wired peripheral. The focus is on physical match and reasonable expectation (e.g., USB-C is commonly used for modern charging and peripherals; Lightning is used on many Apple mobile devices).
Why it appears on the exam
- Identify which physical connector pictured matches the device in a scenario. - Given a user who needs wired file transfer from an older phone, choose microUSB vs. USB-C vs. Lightning. - Decide whether a given accessory cable is physically compatible with the device port in a short scenario.
Key concepts
Concept 1
Required terms
USB: A family of wired physical connectors commonly used for power, data, and peripherals on mobile devices and computers. USB-C: A reversible USB connector type that supports power delivery, data transfer, and alternate modes like video depending on device support. microUSB: A smaller USB connector previously common on phones and some peripherals for charging and data. miniUSB: An older, somewhat larger small USB connector used historically on cameras and older devices for data and power.
Example
A user has an older phone with a wide small connector; identify it as microUSB and recommend the matching cable.

How Compare mobile connection ports and physical plugs works
At the A+ level the candidate should be able to look at a connector or port and identify which family it belongs to and recommend it for a simple task: charging, data sync, or connecting a wired peripheral. The focus is on physical match and reasonable expectation (e.g., USB-C is commonly used for modern charging and peripherals; Lightning is used on many Apple mobile devices).
Example
A laptop with an oval reversible port likely uses USB-C; suggest a USB-C dock or cable if the user needs video or power (confirm device support outside scope).
Concept 3
Common confusion
- USB family vs. connector type: learners conflate USB as the protocol with specific connector forms like USB-C. - Reversibility: confusing USB-C and Lightning as functionally identical; Lightning is proprietary and USB-C capabilities vary by device. - MiniUSB vs microUSB size confusion; encourage side-by-side visual cues.
Example
An iPhone using a small reversible Lightning plug requires a Lightning cable for wired charging/data.
Concept 4
Core 1 (220-1201) question cues
Identify which physical connector pictured matches the device in a scenario; Given a user who needs wired file transfer from an older phone, choose microUSB vs. USB-C vs. Lightning; Decide whether a given accessory cable is physically compatible with the device port in a short scenario.
Example
A user has an older phone with a wide small connector; identify it as microUSB and recommend the matching cable.
Sample questions

Q1.In an A+ question, this detail appears: A laptop with an oval reversible port likely uses USB-C; suggest a USB-C dock or cable if the user needs video or power (confirm device support outside scope). Which option matches it?
Q2.For this A+ objective, the scenario says: A laptop with an oval reversible port likely uses USB-C; suggest a USB-C dock or cable if the user needs video or power (confirm device support outside scope). What is the best match?
Q3.An A+ support scenario describes this situation: A user has an older phone with a wide small connector; identify it as microUSB and recommend the matching cable. Which answer fits best?
