PDF with 98 Questions

You hired a junior engineer to assist you with a large-scale network infrastructure project. The engineer has never worked on such a complex project before and wants to better understand the role that each stakeholder will play in the project.
What is the role of the Network Designer/Architect in this project?

  1. responsible 'or supporting, troubleshooting, and monitoring the wired/wireless infrastructure
  2. responsible for Investigating IDS/IPS Incidents and managing firewalls
  3. responsible for authoring the low-level design and creating the configuration to meet the technical requirements
  4. responsible for establishing security policy and selecting security controls for the infrastructure

Answer(s): C

Explanation:

The role of the Network Designer/Architect in a large-scale network infrastructure project is to develop a detailed technical design that meets the project's requirements. This involves authoring the low-level design documents, which include detailed network diagrams, device configurations, and implementation guidelines. The Network Designer/Architect must understand the technical specifications and business goals to create a solution that is not only technically sound but also aligned with the organization's objectives. This role is critical in ensuring that the network infrastructure is designed to be scalable, reliable, and secure, providing a solid foundation for the organization's operations.



when is o Mode Conditioning Patch Cable required?

  1. A1000Base-LX Transceiver is operated with 62.5/125 cables up to 500 m.
  2. A1000Base-SX Transceiver is operated with 62.5/125 cables up to 500 m.
  3. A10GBase-LXd Transceiver Is operated with 62.5/125 cables up to 2 km.
  4. A10GBase-lR Transceiver is operated with 62 5/125 cables up to 500 m

Answer(s): 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.



DRAG DROP (Drag and Drop is not supported)
You hired a junior engineer to assist you with a large-scale network infrastructure project. The engineer has never worked on such a complex project 'ants to better understand the role that each role that each stakeholder will play in the project.
March the stakeholder title to the responsibilities that would most likely apply to their role.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

CISO: responsible for establishing security policy and selecting security controls for the infrastructure. Network Design/Architecture: responsible for authoring the low-level design, and creating the configuration to meet the technical requirements.
Network Operations: responsible for supporting, troubleshooting, and monitoring the wired/wireless infrastructure.
Security Operations: responsible for investigating IDS/IPS incidents and managing firewalls.



What is the simple difference between a main distribution framework (MOF) closet and an intermediate distribution framework (IDF) closet?

  1. MOF is the point where traffic egresses the campus network, and IDFs distribute that connectivity throughout the building.
  2. MDFs always have larger rooms than IDFs.
  3. MDFs only connect to other MDFs. and IDFs only connect to other IDFs.
  4. MDF Is a term used in Europe whereas the Americas refer to all network closets as IDFs in their documentation.

Answer(s): 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.



Which is true with regard to device capabilities?

  1. Wi-Fi 6E supports 6 GHz for both indoor and outdoor deployments since it was ratified in April of 2020.
  2. Aruba recommends ao-50 devices per radio for a generic office deployment.
  3. You should determine If devices support 2 A GHz or 5 GHz. No consideration Is yet required for 6 GHz as It has yet to be ratified,
  4. Aruba's best practice is to use whatever the AP model supports as a maximum.

Answer(s): B

Explanation:

Aruba's recommendation for device density in a generic office environment is based on achieving optimal performance and user experience. The suggestion to support 30-50 devices per radio takes into account the typical bandwidth requirements, application usage, and performance expectations 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.
