BL0-100 無料問題集「Nokia Bell Labs 5G Foundation」

（A）This network function supports authentication for 3GPP and non-3GPP accesses.

（B）This network function provides registration and discovery functionality to enable other network functions/ services to discover and communicate with each other.

（C）This network function is part of data repositories in the Common Data Layer and in opposition to the UDR, it stores non-standardized unstructured data.

（D）This network function stores or retrieves subscriptions, profiles and authentication data to or from the data repositories. It offers services to the AMF, SMF, NEF and AUSF using the Service Based Interface.

（A）NFV overload control

（B）SDN intrusion control

（C）IoT attack prevention

（D）Security Operation Center

（A）More micro, small and ultra-small cells

（B）Integration of 4G and Wi-Fi radio in 5G access

（C）5G Home box can provide 5G wireless access

（D）Support of wireless backhauling

（A）Cloud software platform

（B）Cloud orchestration

（C）Cloud infrastructure software

（D）Software defined network

（A）Increased throughput per user

（B）Increased transmission robustness with transmit diversity

（C）Reduced latency

（D）Increased spectral density

（A）Increasing the throughput is enough. There is no need to change the network end-to-end.

（B）Increasing the access throughput might be worthwhile but applications that support a higher bit rate should also be a consideration.

（C）Increasing throughput is not enough. A faster and automated transport network, a distributed cloud where applications would run depending on their latency and reliability requirements, a core network that automatically handles any type of access, and a security framework to guarantee the security in every layer of the network are also needed.

（D）The network consists of many layers that include access, transport, core, cloud, and all of the applications running in the cloud. Increasing throughput in access is not enough. The bit rate needs to be increased in all of the other layers as well.

（A）Distributed Unit

（B）Optical Unit

（C）Centralized Unit

（D）Radio Unit
