Pass the Huawei HCIE-Data Center H12-921_V1.0 Questions and answers with CertsForce

Analysis: Bandwidth and latency-sensitive services are generally deployed in edge DCs, such as VR video, cloud gaming, security, and face recognition. Edge DCs are characterized by --- small scale: The network scale of a single edge DC is limited, and there are generally 1~2 groups of leaf devices to provide a small number of computing services. Based on cost considerations, B and D are excluded because the service is sensitive to bandwidth and latency and has a small amount of computation, which is consistent with the edge DC

Resolution: ABC These three options are failures at the protocol layer, while option D is failures at the overlay layer.

Analysis: Ironic is responsible for the management of bare metal services.

Parse:

Resolution: The DHCP Agent is a dynamically assigned IP address L3 Agent: Provides Layer 3 network functions and network address translation functions, allowing tenants' virtual machines to communicate with external networks. In a real-world deployment environment, multiple L3 Agents are typically required to run at the same time. DHCP Agent: Provides dynamic host configuration services to tenant networks, and is mainly used to dynamically assign IP addresses to virtual machines in tenant networks . Plug-in Agent: The plug-in agent needs to be deployed on each host running the hypervisor and provides local virtual switch configuration, depending on the specific plug-in type used. Common agents include ML2 plug-in agents, OpenSwitch agents, and Linux Bridge agents .

Resolution: Both AB and D are block storage.
