NEW QUESTION # 110
gRPC (Google Remote Procedure Call)is a language-neutral, platform-neutral, and open-source remote RPC system that supportsunary RPCs and streaming RPCs.
Which of the following service methodsare NOT supportedby gRPC?

A. rpc Cancel(CancelArgs) returns(CancelReply) {};
B. rpc Subscribe(SubsArgs) stream returns(SubsReply) {};
C. rpc dataPublish(stream serviceArgs) returns(stream serviceArgs) {};
D. rpc stream LotsOfGreetings(HelloRequest) returns (HelloResponse) {};

Answer: C,D

Explanation:
Comprehensive and Detailed Explanation:
#gRPC supports four types of RPCs:
Unary RPC# Client sendsonerequest, server respondsonce.
Server streaming RPC# Server sendsmultiple responses.
Client streaming RPC# Client sendsmultiple requests.
Bidirectional streaming RPC#Bothsides exchange multiple messages.
#Why B and C Are Incorrect:
#(B) Incorrect# The method rpc dataPublish(stream serviceArgs) returns(stream serviceArgs) {} violates gRPC syntax.
#(C) Incorrect# rpc stream LotsOfGreetings(HelloRequest) returns (HelloResponse) {} containsincorrect stream positioning.

NEW QUESTION # 111
The on-premise mode is recommended for controller deployment on small and midsize campus networks.

A. FALSE
B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed
On-premise mode refers to deploying the Huawei iMaster NCE-Campus controller within the enterprise network instead of using a cloud-based solution.
✔ Best suited for small and midsize campus networks that require:
Greater control over data security
Local network automation
No reliance on cloud connectivity
Since on-premise mode is recommended for small and midsize campus networks, the statement is TRUE.

NEW QUESTION # 112
Which of the following statements about static VXLAN tunnel configuration are correct?

A. One NVE interface must be created for each VXLAN tunnel, and the source and destination IP addresses must be specified for the NVE interface. Therefore, the number of NVE interfaces is the same as the number of VXLAN tunnels on the VTEP.
B. One NVE interface must be created for each BD. If there are multiple BDs, multiple NVE interfaces must be created.
C. On an NVE interface, the destination address of a VXLAN tunnel is specified based on the address in the ingress replication list. You can create one NVE interface for multiple VXLAN tunnels.
D. An NVE interface can be associated with multiple VNIs. Therefore, you can create one NVE interface when there are multiple BDs.

Answer: C,D

Explanation:
Understanding VXLAN and NVE Interfaces
VXLAN (Virtual Extensible LAN) allows for Layer 2 network extension over Layer 3 infrastructure.
# Key VXLAN Components:
* NVE (Network Virtualization Edge) Interface # VXLAN tunnels are created using one or more NVE interfaces.
* BD (Bridge Domain) # Logical grouping of VXLAN traffic.
* VNI (VXLAN Network Identifier) # 24-bit unique ID for traffic segmentation.
# Analysis of Each Option:
# A. One NVE interface can be used for multiple VXLAN tunnels if ingress replication is used.
* Correct: VXLAN tunnels can be dynamically learned using BGP EVPN, meaning multiple tunnels can use the same NVE interface.
# B. An NVE interface can be associated with multiple VNIs, allowing multiple BDs on one NVE.
* Correct: Each NVE interface can carry multiple VNIs, reducing the need for separate interfaces.
# C. One NVE interface must be created per VXLAN tunnel.
* Incorrect: Multiple VXLAN tunnels can share a single NVE interface.
# D. One NVE must be created for each BD.
* Incorrect: One NVE can support multiple BDs.
# Real-World Application:
* Cloud Data Centers: VXLAN enables multi-tenant network segmentation.
* Campus Networks: Simplifies Layer 2/Layer 3 connectivity across sites.

B. The Solicited-Node address on the router interface is automatically generated and can have multiple.
C. This is a specific address that is used for resolution in ARPv6 The MAC address.
D. If the Solicited-Node address is not configured , the router automatically generates one on each interface.

Answer: B
