質問 # 89
Which integration capability does gRPC provide?
正解：D
解説：
gRPC provides efficient integration by using protocol buffers to serialize and deserialize structured data over the network. In network programmability and telemetry designs, gRPC is commonly used as the transport framework for streaming model-driven telemetry or for remote procedure calls between collectors, controllers, and network devices. Protocol buffers define compact structured messages that are faster and less ambiguous than parsing text output. This makes gRPC suitable for high-volume telemetry and programmatic device interaction. LDAP is a directory and authentication-related protocol, not the integration mechanism provided by gRPC. XMPP is associated with messaging and presence systems, not gRPC data serialization.
Graph API is not a gRPC feature. The operational value of gRPC is that it provides a modern RPC framework with efficient message encoding, service definitions, and support for secure transport through TLS when implemented by the platform. Reference topics: gRPC, protocol buffers, model-driven telemetry, network programmability, structured data serialization. It improves controller interoperability.
質問 # 90
A network architect Is enabling TV services In the LAN. The source will be streaming to the 239.1.1.1 group IP address. Dense mode Is not allowed In the network. Multicast has already been enabled on all network devices In the LAN segment. Which action must the architect take to finalize the design?
正解：A
質問 # 91
A network engineer must design a multicast solution based on these requirements:
* interactive communication
* must not use source trees
* users must register
* 100 multicast sources
Which solution must the company choose?
正解：D
解説：
BIDIR-PIM is the correct multicast solution for interactive many-to-many communication with many sources when source trees must not be used. Bidirectional PIM is specifically designed for applications where receivers can also be senders and where the number of sources can grow without creating per-source multicast state throughout the network. Instead of building shortest-path trees for each source, BIDIR-PIM uses a shared tree rooted at the rendezvous point and forwards traffic bidirectionally along that tree. This reduces multicast routing-table growth and control-plane churn in environments with many active sources. PIM dense mode is not appropriate because it floods and prunes traffic and is inefficient at scale. Any-source multicast with PIM-SM may create source trees, which violates the requirement. MSDP is used to exchange source information between PIM-SM domains and is not itself the forwarding mode for this campus or WAN multicast design. Reference topics: BIDIR-PIM, many-to-many multicast, shared tree, multicast source scaling, PIM design.
