What is the primary function of the DU in 5G architecture?

  1. To provide user plane connectivity

  2. To provide control plane connectivity

  3. To manage radio resources

  4. To handle mobility management

Show answer
Correct Option: C
Explanation:

The DU is responsible for managing radio resources, such as allocating and scheduling spectrum, and performing interference management.

Which of the following is NOT a component of the 5G DU architecture?

  1. Central Unit (CU)

  2. Distributed Unit (DU)

  3. Radio Unit (RU)

  4. Core Network (CN)

Show answer
Correct Option: D
Explanation:

The Core Network is not a component of the 5G DU architecture. It is a separate network that provides connectivity between different parts of the 5G network.

Correct Option: D
Explanation:

A distributed DU architecture in 5G offers reduced latency, increased capacity, and improved coverage.

What is the term used to describe the interface between the CU and the DU in 5G?

  1. F1 interface

  2. E1 interface

  3. N1 interface

  4. X2 interface

Show answer
Correct Option: A
Explanation:

The F1 interface is used to connect the CU and the DU in 5G.

Which of the following is NOT a type of DU deployment model in 5G?

  1. Centralized DU

  2. Distributed DU

Beamforming RU is not a type of RU in 5G.

What is the term used to describe the interface between the RU and the DU in 5G?

  1. F1 interface

  2. E1 interface

  3. N1 interface

  4. X2 interface

Show answer
Correct Option: B
Explanation:

The E1 interface is used to connect the RU and the DU in 5G.

Which of the following is NOT a benefit of using a distributed DU architecture in 5G?

  1. Reduced latency

  2. Increased capacity

Show answer
Correct Option: D
Explanation:

Increased complexity is not a benefit of using a distributed DU architecture in 5G.

What is the term used to describe the interface between the CU and the CN in 5G?

  1. F1 interface

  2. E1 interface

  3. N1 interface

  4. X2 interface

Show answer
Correct Option: C
Explanation:

The N1 interface is used to connect the CU and the CN in 5G.

Which of the following is NOT a function of the CU in 5G architecture?

  1. Radio resource management

  2. Mobility management

  3. Packet processing

  4. User plane data forwarding

Show answer
Correct Option: D
Explanation:

User plane data forwarding is not a function of the CU in 5G architecture.

What is the term used to describe the interface between the DU and the CN in 5G?

  1. F1 interface

  2. E1 interface

  3. N1 interface

  4. X2 interface

Show answer
Correct Option: D
Explanation:

The X2 interface is used to connect the DU and the CN in 5G.

Which of the following is NOT a type of DU in 5G?

  1. Centralized DU

  2. Distributed DU

  3. Hybrid DU

  4. Virtualized DU

Show answer
Correct Option: A
Explanation:

Centralized DU is not a type of DU in 5G.

What is the term used to describe the interface between the RU and the CN in 5G?

  1. F1 interface

  2. E1 interface

  3. N1 interface
