Quick Answer
The correct match is satellite with uses geostationary or LEO orbit because satellite broadband relies on radio frequency (RF) transmission to and from orbiting satellites, rather than terrestrial cabling. DSL operates over twisted-pair telephone lines, cable broadband uses coaxial cable, fiber broadband transmits light through optical fibers, and 4G LTE depends on cellular towers. On the ENCOR 350-401 exam, this drag-and-drop task tests your ability to distinguish physical-layer transport media for WAN access technologies, a common topic in the network fundamentals section. A frequent trap is confusing cable with DSL, since both use copper, but cable employs coaxial while DSL uses telephone-grade twisted pair. For a quick memory tip, think of the first letter of each technology: DSL uses copper phone lines (D for dial tone), Cable uses coaxial (C for coax), Fiber uses glass (F for filament), LTE uses cellular (L for long-range), and Satellite uses space (S for sky).
CCNP WAN Technologies Practice Question
This 350-401 practice question tests your understanding of wan technologies. 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.
Drag and drop each broadband type on the left to its matching technology on the right.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DSL: Uses telephone copper pairs
DSL uses telephone lines, Cable uses coaxial, Fiber uses optical, 4G LTE uses cellular, Satellite uses RF to orbit.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-401 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

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. Drag and drop each broadband type on the left to its matching technology on the right.
easy- ✓ P1.DSL: Uses telephone line with ADSL or VDSL
- ✓ P2.Cable: Uses coaxial cable with DOCSIS
- ✓ P3.Fiber: Uses optical fiber with GPON
- ✓ P4.4G LTE: Uses cellular radio with OFDMA
- ✓ P5.Satellite: Uses geostationary satellite with high latency
Why P1: DSL uses telephone lines with frequencies above voice. Cable uses coaxial cable with DOCSIS. Fiber uses optical fiber with GPON or active Ethernet. 4G LTE uses cellular radio. Satellite uses geostationary or LEO satellites.
