Quick Answer
The answer is fiber-optic internet. This is the correct choice because fiber-optic technology transmits data as light pulses through glass strands, inherently providing symmetrical speeds—meaning identical upload and download rates—which is essential for cloud applications that demand fast, bidirectional data flow for tasks like real-time collaboration, backups, and VoIP. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of internet connection types and their suitability for business environments; a common trap is assuming cable broadband is sufficient due to its high download speeds, but its asymmetrical design (slower uploads) makes it a poor fit for cloud-centric workloads. Remember the memory tip: “Fiber is for flow—symmetrical both ways; cable is for catch—fast down, slow up.”
This 220-1201 practice question tests your understanding of internet connection types. 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 small business is moving to a new office that already has a fiber-optic termination point installed. They need the fastest symmetrical speeds for cloud-based applications. Which internet connection type should they choose?
DSL
Why wrong: DSL uses phone lines and offers much lower speeds than fiber.
Cable broadband
Why wrong: Cable broadband has asymmetrical speeds, with slower uploads than fiber.
Fiber-optic
Fiber provides symmetrical high-speed connections, perfect for cloud applications.
Satellite
Why wrong: Satellite has high latency and lower speeds, unsuitable for cloud-based work.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Fiber-optic
Fiber-optic internet provides symmetrical upload and download speeds, ideal for cloud applications. Cable broadband offers high download speeds but slower uploads, while DSL and satellite are slower and often asymmetrical. Fiber is the best fit when the infrastructure is already in place.
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
For each option: why learners choose it and why it is or isn't the right answer here.
DSL
Why it's wrong here
DSL uses phone lines and offers much lower speeds than fiber.
Cable broadband
Why it's wrong here
Cable broadband has asymmetrical speeds, with slower uploads than fiber.
Fiber-optic
Why this is correct
Fiber provides symmetrical high-speed connections, perfect for cloud applications.
Related concept
Static NAT maps one inside address to one outside address.
Satellite
Why it's wrong here
Satellite has high latency and lower speeds, unsuitable for cloud-based work.
Common exam traps
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
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.
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
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 220-1201 NAT questions on configuration and troubleshooting.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is moving to a new building that has no existing internet infrastructure. They need the highest possible download speeds with low latency for cloud applications. Which connection type should they choose?
hardWhy D: Fiber optic internet provides the highest speeds and lowest latency among common connection types, making it ideal for cloud applications. While installation may require new cabling, it offers symmetrical speeds and minimal signal degradation over long distances.
Variation 2. An IT manager is comparing cable broadband and fiber-optic for a new office. They need the lowest possible latency for real-time financial trading applications. Which connection type should they choose, and why?
hardWhy D: Fiber-optic offers the lowest latency due to light transmission and dedicated bandwidth, essential for real-time trading. Cable broadband has higher latency due to shared bandwidth and signal conversion. Fiber's physical properties make it superior for latency-sensitive applications.
