- A
Local Area Network (LAN)
Why wrong: A LAN is confined to a single building or campus and cannot connect locations across different states.
- B
Metropolitan Area Network (MAN)
Why wrong: A MAN covers a city-sized area, but New York, Los Angeles, and Chicago are far apart, exceeding a MAN's range.
- C
Wide Area Network (WAN)
A WAN is designed to connect multiple sites over large geographic distances, such as across the country, and can use leased lines for high bandwidth.
- D
Personal Area Network (PAN)
Why wrong: A PAN covers only a few meters and is not applicable for inter-city connections.

220-1201 Network Types Practice Question
This 220-1201 practice question tests your understanding of network 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 large corporation needs to connect its headquarters in New York to a regional office in Los Angeles, as well as to a data center in Chicago, using dedicated leased lines. The network must support high bandwidth for video conferencing and data transfers. Which network topology best describes this setup?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
✓
Wide Area Network (WAN)
A Wide Area Network (WAN) is the correct topology because it connects geographically dispersed locations—New York, Los Angeles, and Chicago—over a large geographical area using dedicated leased lines (e.g., T1/E1, T3, or MPLS circuits). WANs are specifically designed to provide high-bandwidth, reliable connectivity for applications like video conferencing and data transfers across cities or countries, which matches the requirement for dedicated leased lines spanning multiple states.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
A PAN covers only a few meters and is not applicable for inter-city connections.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse a MAN with a WAN because both cover multiple locations, but a MAN is limited to a single metropolitan area (e.g., connecting buildings in Los Angeles), whereas the question explicitly involves three cities across the U.S., which requires a WAN.
Detailed technical explanation
How to think about this question
Dedicated leased lines in a WAN often use point-to-point protocols like HDLC or PPP, with Layer 2 encapsulation such as Frame Relay or MPLS for traffic engineering. In real-world deployments, organizations may use Carrier Ethernet or SD-WAN over leased lines to dynamically route traffic, but the fundamental topology remains a WAN because the links traverse public or private carrier infrastructure across state boundaries, requiring routing protocols like BGP or OSPF to manage connectivity between sites.
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.
TExam Day Tips
- 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 220-1201 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.
