Multiple choice

What is the primary objective of network slicing in 5G?

  1. To improve network performance

  2. To reduce network costs

  3. To increase network security

  4. To enhance network flexibility
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Network slicing in 5G aims to enhance network flexibility by allowing multiple logical networks to coexist on a single physical infrastructure, enabling customized network services for different applications and use cases.

Multiple choice

Which of the following is NOT a key characteristic of 5G network slicing?

  1. Isolation

  2. Multi-tenancy

  3. Scalability

  4. Aggregation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Aggregation is not a key characteristic of 5G network slicing. Isolation, multi-tenancy, and scalability are the primary characteristics that define network slicing in 5G.

Multiple choice

Which component of the 5G network architecture is responsible for managing and coordinating network slices?

  1. Network Slice Manager (NSM)

  2. Slice Controller (SC)

  3. Slice Orchestrator (SO)

  4. Slice Broker (SB)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Network Slice Manager (NSM) is the central entity responsible for managing and coordinating network slices in a 5G network. It interacts with other network components to create, modify, and terminate slices, ensuring their proper operation and resource allocation.

Multiple choice

What is the primary function of a Slice Controller (SC) in 5G network slicing?

  1. Managing slice resources

  2. Configuring network elements

  3. Enforcing slice policies

  4. Monitoring slice performance
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The primary function of a Slice Controller (SC) in 5G network slicing is to enforce slice policies. It ensures that each slice adheres to its defined parameters, such as bandwidth, latency, and security requirements, by configuring and controlling network resources accordingly.

Multiple choice

Which of the following is NOT a type of network slice isolation in 5G?

  1. Logical isolation

  2. Physical isolation

  3. Temporal isolation

  4. Resource isolation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Temporal isolation is not a type of network slice isolation in 5G. Logical isolation, physical isolation, and resource isolation are the primary isolation mechanisms used to ensure the separation and protection of different network slices.

Multiple choice

Which of the following is NOT a benefit of using network slicing in 5G?
