Question #6
All ODN parts in POL are passive optical components?
- A . TRUE
- B . FALSE
Correct Answer: A
A
Explanation:
In a Passive Optical LAN (POL), the Optical Distribution Network (ODN) consists entirely of passive optical components such as splitters, connectors, and fibers. These components do not require external power, making them fully passive.
The ODN in POL follows Point-to-Multipoint (P2MP) architecture using passive splitters, ensuring signal distribution without electrical conversion. Since no active components are present in the ODN, it remains maintenance-free and energy-efficient.

DC908 does not support co-deployment with IT devices in the same rack.
- A . TRUE
- B . FALSE
Correct Answer: B
B
Explanation:
The DC908 is designed for DCI with IT compatibility. HCSA-Sales-Transmission & Access confirms it supports co-deployment with IT devices in the same rack, featuring a 2U form factor, front-to-rear airflow, and rack-standard dimensions (e.g., 19-inch ETSI). The statement’s negation is incorrect, making it FALSE.

Question #8
PON is short for Passive Optical Network. It is a point-to-point (P2P) access mode.
- A . TRUE
- B . FALSE
Correct Answer: B
B
Explanation:
PON is Passive Optical Network, but it uses a point-to-multipoint (P2MP) topology, not P2P, per HCSA-Sales-Transmission & Access. P2P dedicates a fiber per user, while PON shares via splitters, making the statement FALSE.

Question #10
Which of the following challenges are Campus Networks facing?
- A . Hard to expand/upgrade cabling system
- B . Restriction of 100m makes network complex
- C . Devices are too large
- D . Chimney networks hard to maintain
Correct Answer: A, D
A, D
Explanation:
Campus networks today face several key challenges:
✅ Hard to expand/upgrade cabling system C Traditional Ethernet-based campus networks require
extensive copper cabling, which is difficult to expand and upgrade, leading to higher costs and complexity.
✅ Chimney networks hard to maintain C Many legacy campus networks operate in a chimney-style architecture (vertical silos of network systems), making it difficult to manage and integrate different services.
❌ Restriction of 100m makes network complex C While Ethernet has a 100m distance limit, modern fiber-based Passive Optical LAN (POL) solutions overcome this restriction, making this less of a challenge today.
❌ Devices are too large C Modern networking equipment is compact and modular, making device size less of a concern in today’s campus networks.
Thus, the correct answers are A and D.
