Nokia 5G RAN Network Operations Expert Sample Questions:
1. For security segmentation, NOC personnel typically do not connect directly from their workstations to production AirScale base stations. Instead, they first authenticate to an intermediate, hardened host. What is this intermediate host commonly called?
A) Jump server / bastion host
B) Load balancer
C) DNS server
D) Edge router
2. Which AirScale management tool allows an engineer to connect directly to a single base station for local-level configuration viewing and diagnostics, as opposed to network-wide centralized management?
A) NetAct PM Reports
B) NetAct CM Editor
C) BTS Site Manager (local Element Manager)
D) SON Network Optimizer
3. A NOC engineer needs to recover a base station from a state where its parameter settings have been corrupted, but the underlying software load is functioning correctly. Which type of backup would be most directly applicable to resolving this specific issue?
A) A software backup only, since configuration data is always embedded within the software image itself
B) A configuration backup, since it contains the parameter data needed to restore the element's settings without requiring a software reinstallation
C) An alarm history export, since it contains the parameter values needed for restoration
D) A PM counter export, since it records the configuration state at each reporting interval
4. Before activating a newly downloaded software package on a base station, why is it important to verify software compatibility with the unit's current hardware and configuration?
A) Because software compatibility checks are only relevant for 2G equipment and do not apply to 5G base stations
B) Because activating an incompatible software package can result in activation failure, degraded functionality, or the unit failing to return to normal operation, even if the automatic fallback eventually recovers it
C) Because compatibility checks automatically update the site's physical inventory records
D) Because compatibility verification eliminates the need for any post-activation monitoring
5. What is the primary purpose of the Xn interface in a 5G RAN architecture?
A) It is used exclusively for software downloads from NetAct to the base station
B) It connects the RF unit to the baseband unit within a single base station
C) It connects the gNB to the core network for user authentication only
D) It provides direct communication between gNBs to support functions such as handover signaling and data forwarding during mobility
