Free Nokia Bell Labs 5G Networking Exam BL0-200 Exam Practice Test

Ethernet Virtual Private Networks enables :

• Network virtualization in data centers
  
• Enables dynamic traffic engineering services
  
• Segment routing-traffic engineering
  
• Exposes the full topology to the SON Controller
  

In an SDN network the traffic engineering is:

• typically conducted by operators on a yearly or quarterly basis
  
• conducted near real-time, on a granular second or minute basis
  
• conducted offline
  
• conducted by the operators upon the appearance of a problem
  

Which transport network segment is between the gNB radio and DU function?

• Longhaul
  
• Midhaul
  
• Backhaul
  
• Fronthaul

• Core
  
• UE
  
• 5G RAN
  
• Cloud
  

Frequency synchronization can be distributed via Synchronous Ethernet. Please select true statement for SynchE.

• SynchE is a layer 2 - link layer
  
• The stability of the recovered frequency depends on the network load
  
• SynchE must be supported at all intermediate nodes on the synchronization path
  
• SynchE is transported in OTN frames

Which of the following is NOT a functionality of Network Slice Selection Function (NSSF)?

• Takes care of mapping slice specific identifiers.
  
• Determines the candidate AMFs to be used to serve the UE.
  
• Selects the slices to which the UE can connect.
  
• Provides policies directly to the UPF for implementation, in the form of slices.
  

Which of the following Is a functionality of the User Plane Function (UPF)?

• Connects to external networks via N8 reference point
  
• Sends traffic usage reporting to the SMF for charging
  
• Enforces policies received from NSSAI and applies them as slices.
  
• Acts as the interconnection point with Non-3GPP Access networks
