Question 7
when is o Mode Conditioning Patch Cable required?
- A. A1000Base-LX Transceiver is operated with 62.5/125 cables up to 500 m.
- B. A1000Base-SX Transceiver is operated with 62.5/125 cables up to 500 m.
- C. A10GBase-LXd Transceiver Is operated with 62.5/125 cables up to 2 km.
- D. A10GBase-lR Transceiver is operated with 62 5/125 cables up to 500 m
Answer:
A
Explanation:
Mode Conditioning Patch Cables (MCPs) are used in situations where long wavelength laser
transceivers, such as the 1000Base-LX, are deployed over multimode fiber types like the 62.5/125
µm. The 1000Base-LX transceivers are designed primarily for use with single-mode fiber, but they can
operate over multimode fiber using an MCP. The MCP is necessary because the core size of
multimode fiber (62.5/125 µm) is significantly larger than that of single-mode fiber, which can lead
to modal dispersion when a single-mode laser signal enters the multimode fiber. This dispersion can
degrade the signal quality over longer distances. The MCP mitigates this issue by aligning the single-
mode laser output from the transceiver to a specific launch point in the multimode fiber, thus
minimizing dispersion and allowing for effective data transmission over distances up to 500 meters.

Question 9
What is the simple difference between a main distribution framework (MOF) closet and an
intermediate distribution framework (IDF) closet?
- A. MOF is the point where traffic egresses the campus network, and IDFs distribute that connectivity throughout the building.
- B. MDFs always have larger rooms than IDFs.
- C. MDFs only connect to other MDFs. and IDFs only connect to other IDFs.
- D. MDF Is a term used in Europe whereas the Americas refer to all network closets as IDFs in their documentation.
Answer:
A
Explanation:
In network design, the Main Distribution Frame (MDF) and Intermediate Distribution Frame (IDF) are
critical components of the network infrastructure. The MDF is the primary hub of the network, often
where services from outside the campus or building enter and get distributed. It acts as a central
point for network distribution. On the other hand, IDFs are secondary hubs situated throughout the
building or campus, extending connectivity provided by the MDF to various endpoints or areas within
the building. The simple difference between them lies in their roles within the network
infrastructure: the MDF serves as the main point of network ingress and egress, while IDFs are used
to further distribute the network to specific locations or floors within the building.

in an office setting. This range is designed to ensure that the wireless network can adequately
support the number of devices without significant degradation in service quality. It balances the
need for connectivity with the practical limits of wireless technology, ensuring that each device
maintains a reliable connection and adequate throughput. This recommendation is part of Aruba's
best practices for network design and deployment, aimed at providing efficient and effective wireless
coverage in office environments.
Question 11
What is one use case for designing a 2-tier campus LAM instead of using a 3-tier?
- A. The campus has small buildings with only a few wiring closets.
- B. The network has grown beyond a few building aggregation points
- C. Access aggregation points are not scaling to meet traffic demands.
- D. Cross-campus traffic has grown beyond We capacity of a single collapsed core
Answer:
A
Explanation:
A 2-tier campus LAN architecture, consisting of the core and access layers, is typically suitable for
smaller campuses or networks with limited numbers of wiring closets. This simplified architecture
eliminates the need for a dedicated aggregation layer, which is more common in larger, more
complex network environments (the 3-tier architecture). In a small campus setting with only a few
wiring closets, a 2-tier design can provide sufficient performance and scalability, reducing complexity
and potentially lowering costs. This architecture allows for direct connectivity between the access
layer, where end devices connect to the network, and the core layer, which routes traffic to and from
the campus network. The use of a 2-tier architecture in such scenarios is driven by the network's size
and the simplicity of its requirements, making it an efficient and effective choice.
