Controller interconnection with external systems can be mandatory or optional depending on functionality. Let&#8217;s evaluate each option:<br\/>A . Interconnection with FabricInsight: This is optional. FabricInsight is an analytics and assurance tool that enhances visibility and troubleshooting but is not required for basic controller operations in the computing scenario. OPTIONAL.<br\/>B . Interconnection with the authentication server: This is mandatory. Authentication servers (e.g., RADIUS, TACACS+) are essential for securing access to the controller and managed devices, a core requirement in computing scenarios. NOT OPTIONAL.<br\/>C . Interconnection with eSight: This is optional. eSight is a network management platform that provides additional monitoring and management capabilities, but it is not necessary for core controller functionality. OPTIONAL.<br\/>D . Interconnection with the VMM (Virtual Machine Manager): This is mandatory. Interconnection with a VMM (e.g., FusionCompute, OpenStack) is required to manage virtualized computing resources and orchestrate network services in the computing scenario.

The method of data collection is critical for network monitoring.<br\/>SNMP Usage: Simple Network Management Protocol (SNMP) is a traditional method for collecting alarms and logs from network devices. However, Huawei&#8217;s modern SDN controllers, including iMaster NCE-Fabric, primarily use telemetry (e.g., gRPC, NETCONF) for real-time data collection from physical devices and vSwitches. Telemetry provides higher efficiency and granularity compared to SNMP.<br\/>CloudFabric Approach: The solution leverages telemetry-based data collection, as documented in FabricInsight and iMaster NCE-Fabric guides, to gather alarms, logs, and performance metrics. SNMP may be supported as a legacy option but is not the primary method in this context.<br\/>The statement is FALSE (B) because iMaster NCE-Fabric predominantly uses telemetry, not SNMP, for collecting alarms and logs.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(3,this)' id='btn-3' value='See Answer'  \/><input type='hidden' id='questionType3' value='radio' class=''><\/div><div class='watu-question' id='question-4'><div class='question-content'><p><strong>NO.30<\/strong> A VXLAN tunnel is identified by a pair of VTEP IP addresses.

This pair ensures the tunnel is specific to the communication path between the two VTEPs.<br\/>Tunnel Establishment: During setup, VTEPs exchange information to learn each other&#8217;s IP addresses. This can occur manually (static configuration) or dynamically (e.g., via BGP EVPN). The underlay network must provide Layer 3 reachability between the VTEP IP addresses, typically using routing protocols (e.g., OSPF, BGP) to ensure IP connectivity.<br\/>Reachability Condition: If the local and remote VTEP IP addresses are reachable at Layer 3, the tunnel can be established, allowing encapsulation and decapsulation of VXLAN traffic.

Within a CloudFabric network, VXLAN encapsulation is used to transport traffic across the fabric, enabling overlay networking for VMs. TRUE.<br\/>B . Inter-VPC traffic must pass through the firewall: This is false. Inter-VPC (Virtual Private Cloud) traffic can be routed directly between VPCs using a gateway or router (e.g., with EVPN Type 5 routes) without necessarily passing through a firewall, depending on security policies. Firewalls are optional for inter-VPC traffic, not mandatory. FALSE.<br\/>C . Traffic between VAS devices and service leaf nodes is VLAN encapsulated: This is true. Value-Added Services (VAS) devices (e.g., load balancers) often connect to service leaf nodes using VLAN encapsulation, especially in traditional or hybrid deployments. TRUE.<br\/>D . Traffic between vSwitches on virtual servers and server leaf nodes is VLAN encapsulated: This is true. Traffic from virtual switches (vSwitches) on hypervisors to physical server leaf nodes typically uses VLAN encapsulation over the physical NICs, before VXLAN overlay if applicable. TRUE.<br\/>Thus, B is the false statement because inter-VPC traffic does not always require a firewall.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(5,this)' id='btn-5' value='See Answer'  \/><input type='hidden' id='questionType5' value='radio' class=''><\/div><div class='watu-question' id='question-6'><div class='question-content'><p><strong>NO.32<\/strong> Which of the following statements is false about VXLAN tunnel establishment?<\/p>\n<\/div><input type='hidden' name='question_id[]' value='16690' \/><div class='watu-questions-wrap '><input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='64489' \/><div class='watu-question-choice'><input type='radio' name='answer-16690[]' id='answer-id-64489' class='answer answer-6 js-answer-label answerof-16690' value='64489' \/>&nbsp;<label for='answer-id-64489' id='answer-label-64489' class='js-answer-label answer label-6'><span class='answer'>A VXLAN tunnel is identified by a pair of VTEPs.<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='64490' \/><div class='watu-question-choice'><input type='radio' name='answer-16690[]' id='answer-id-64490' class='answer answer-6 js-answer-label answerof-16690' value='64490' \/>&nbsp;<label for='answer-id-64490' id='answer-label-64490' class='js-answer-label answer label-6'><span class='answer'>After a tunnel is established, if one end of the tunnel goes Down, the other end may not go Down.<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='64491' \/><div class='watu-question-choice'><input type='radio' name='answer-16690[]' id='answer-id-64491' class='answer answer-6 js-answer-label answerof-16690' value='64491' \/>&nbsp;<label for='answer-id-64491' id='answer-label-64491' class='js-answer-label answer label-6'><span class='answer'>For a static tunnel, you need to manually configure the local and remote VNIs.<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='64492' \/><div class='watu-question-choice'><input type='radio' name='answer-16690[]' id='answer-id-64492' class='answer answer-6 php-answer-label answerof-16690' value='64492' \/>&nbsp;<label for='answer-id-64492' id='answer-label-64492' class='php-answer-label answer label-6'><span class='answer'>Dynamic tunnels depend on EVPN Type 5 routes to transmit information.<\/span><\/label><\/div>\n<\/div><div class='show-question-feedback' style='display:none;'>VXLAN (Virtual Extensible LAN) tunnels are used to encapsulate Layer 2 traffic over a Layer 3 network, a key component in Huawei&#8217;s CloudFabric data center solutions. Let&#8217;s evaluate each statement:<br\/>A . A VXLAN tunnel is identified by a pair of VTEPs: This is true. A VXLAN tunnel is identified by the pair of VXLAN Tunnel Endpoint (VTEP) IP addresses (local and remote), along with the VNI (VXLAN Network Identifier). This ensures unique tunnel identification. TRUE.<br\/>B . After a tunnel is established, if one end of the tunnel goes Down, the other end may not go Down: This is true. VXLAN tunnels are unidirectional, and the status of one end does not automatically affect the other unless the underlay network connectivity (e.g., Layer 3 reachability) is lost. The remote VTEP may remain operational if it can still encapsulate\/decapsulate traffic. TRUE.<br\/>C . For a static tunnel, you need to manually configure the local and remote VNIs: This is true. In a static VXLAN tunnel, administrators must manually configure the VNI and VTEP IP addresses on both ends, as there is no dynamic control plane (e.g., BGP EVPN) to automate the process. TRUE.<br\/>D . Dynamic tunnels depend on EVPN Type 5 routes to transmit information: This is false. Dynamic VXLAN tunnels rely on BGP EVPN as the control plane, but Type 5 routes (IP Prefix routes) are specifically used for advertising host IP routes and external network routes, not for general tunnel establishment. Dynamic tunnel setup primarily uses Type 2 (MAC\/IP Advertisement) and Type 3 (Multicast) routes to exchange VNI and VTEP information. Type 5 routes are relevant for Layer 3 routing, not the initial tunnel setup.

Let&#8217;s evaluate each function:<br\/>A . The NIC Driver Sends Data Frames: Network Interface Card (NIC) drivers operate in kernel space, managing hardware interactions like sending and receiving data frames. This is a low-level task requiring direct hardware access, handled by the kernel&#8217;s network stack. Included in Kernel Space.<br\/>B . Data Encapsulation: Data encapsulation (e.g., adding headers in the TCP\/IP stack) occurs in the kernel&#8217;s network subsystem (e.g., via the protocol stack like IP or TCP). This process prepares packets for transmission and is a kernel-space function. Included in Kernel Space.<br\/>C . Bit Stream Transmission: This refers to the physical transmission of bits over the network, managed by the NIC hardware and its driver in kernel space. The kernel coordinates with the NIC to send bit streams, making this a kernel-space function. Included in Kernel Space.<br\/>D . Data Encryption: Encryption (e.g., via OpenSSL or application-level VPNs) typically occurs in user space, where applications or libraries handle cryptographic operations. While the kernel supports encryption (e.g., IPsec in the network stack), the actual encryption logic is often offloaded to user-space tools, not a core kernel function in standard contexts. Not Typically in Kernel Space.<br\/>Thus, A, B, and C are functions included in the kernel space, aligning with Linux architecture in Huawei&#8217;s DCN context.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(8,this)' id='btn-8' value='See Answer'  \/><input type='hidden' id='questionType8' value='checkbox' class=''><\/div><div class='watu-question' id='question-9'><div class='question-content'><p><strong>NO.35<\/strong> BGP EVPN defines several types of BGP EVPN routes by extending BGP.

FTP servers are typically used for file storage.<br\/>This is correct. FTP (File Transfer Protocol) servers are indeed a common way to store and share files. They are widely used for basic file storage and transfer needs.<br\/>B . Object storage devices are typically disk arrays.<br\/>This is incorrect. Object storage devices are not typically disk arrays in the traditional sense. Object storage is designed for massive amounts of unstructured data. While they use disks for persistence, they present data as objects with metadata, rather than as blocks or files. Object storage solutions often use distributed systems across many servers, not just a single array.<br\/>C . Block storage applies to databases that require high I\/O.<br\/>This is correct. Block storage is ideal for applications that demand high I\/O performance, such as databases. Block storage provides raw, unformatted data blocks, giving applications direct control and low latency.<br\/>D . Block storage typically applies to remote backup storage.<br\/>This is partially true, but not the typical primary use case. While block storage can be used for remote backups, it is generally considered less efficient and more expensive than object storage for this purpose. Object storage is better suited for large, unstructured backup datasets. Block storage is better for applications that need fast read\/write speeds, such as databases and virtual machines.<br\/>Therefore, the correct answers are A and C.<br\/>Reference to Huawei Data Center Network documents:<br\/>Huawei storage product documentation detailing block storage (e.g., OceanStor Dorado), file storage, and object storage (e.g., OceanStor Pacific) characteristics and use cases.<br\/>Huawei white papers on data center storage architectures, which compare and contrast different storage types.<br\/>Huawei HCIP-Storage training materials, which will have very detailed information regarding each of the storage types, and their use cases.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(10,this)' id='btn-10' value='See Answer'  \/><input type='hidden' id='questionType10' value='checkbox' class=''><\/div><div class='watu-question' id='question-11'><div class='question-content'><p><strong>NO.37<\/strong> Which of the following are the application scenarios of Huawei CloudFabric Solution?

Leaf nodes can serve different roles:<br\/>Border Leaf Node: Connects the DCN to external networks or other domains, handling Layer 3 routing.<br\/>Service Leaf Node: Connects to internal services (e.g., servers, VMs), often handling Layer 2\/Layer 3 traffic.<br\/>In practice, a single physical device can be configured to perform both roles (border and service) if it has the necessary interfaces and routing capabilities. Huawei&#8217;s CloudFabric documentation supports this flexibility, allowing a leaf switch to act as both a border and service node based on configuration (e.g., using VRFs or VXLAN gateways). This reduces hardware costs and simplifies deployment in smaller DCNs.<br\/>The statement is TRUE (A) because the border leaf and service leaf roles can be deployed on the same device in a spine-leaf architecture.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(14,this)' id='btn-14' value='See Answer'  \/><input type='hidden' id='questionType14' value='radio' class=''><\/div><div class='watu-question' id='question-15'><div class='question-content'><p><strong>NO.41<\/strong> In the DCN architecture, spine nodes connect various network devices to the VXLAN network.<\/p>\n<\/div><input type='hidden' name='question_id[]' value='16699' \/><div class='watu-questions-wrap '><input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='64520' \/><div class='watu-question-choice'><input type='radio' name='answer-16699[]' id='answer-id-64520' class='answer answer-15 php-answer-label answerof-16699' value='64520' \/>&nbsp;<label for='answer-id-64520' id='answer-label-64520' class='php-answer-label answer label-15'><span class='answer'>TRUE<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='64521' \/><div class='watu-question-choice'><input type='radio' name='answer-16699[]' id='answer-id-64521' class='answer answer-15 js-answer-label answerof-16699' value='64521' \/>&nbsp;<label for='answer-id-64521' id='answer-label-64521' class='js-answer-label answer label-15'><span class='answer'>FALSE<\/span><\/label><\/div>\n<\/div><div class='show-question-feedback' style='display:none;'>In Huawei&#8217;s Data Center Network (DCN) architecture, particularly with the CloudFabric solution, the spine-leaf topology is a common design for scalable and efficient data centers. VXLAN (Virtual Extensible LAN) is used to create overlay networks, enabling large-scale multi-tenancy and flexible workload placement.<br\/>Spine Nodes&#8217; Role: In this architecture, spine nodes act as the backbone, interconnecting leaf nodes (which connect to servers, storage, or other endpoints) and facilitating high-speed, non-blocking communication. Spine nodes typically handle Layer 3 routing and serve as VXLAN tunnel endpoints (VTEPs) or connect to devices that do, integrating the physical underlay with the VXLAN overlay network.<br\/>Connection to VXLAN: Spine nodes ensure that traffic from various network devices (via leaf nodes) is routed efficiently across the VXLAN fabric. They provide the high-bandwidth, low-latency backbone required for east-west traffic in modern data centers, supporting VXLAN encapsulation and decapsulation indirectly or directly depending on the deployment.<br\/>Thus, the statement is TRUE (A) because spine nodes play a critical role in connecting the underlay network (various devices via leaf nodes) to the VXLAN overlay, as per Huawei&#8217;s DCN design principles.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(15,this)' id='btn-15' value='See Answer'  \/><input type='hidden' id='questionType15' value='radio' class=''><\/div><div class='watu-question' id='question-16'><div class='question-content'><p><strong>NO.42<\/strong> Which of the following are advantages of iMaster NCE-FabricInsight&#8217;s telemetry-based performance metric collection?

In loose mode, inconsistencies in Type 1 (key) configurations are still critical, as they can affect M-LAG operation. According to Huawei M-LAG Configuration Guide, when Type 1 configurations are inconsistent in loose mode, the system may place the member interface on the backup device into an Error-Down state and generate an alarm to alert administrators. This ensures that critical issues are flagged, even in loose mode, to prevent loops or packet loss.<br\/>Conclusion: True.<br\/>Option B: If Type 1 configurations of the two M-LAG member devices are inconsistent, certain problems may occur, such as loops and long-period packet loss when the status is normal.<br\/>Evaluation: This statement is true. Type 1 configurations are essential for M-LAG operation, and inconsistencies can lead to severe network issues. For example, mismatched LACP settings or VLAN mappings can create loops or cause packet loss, as noted in Arista M-LAG Documentation. These problems can persist even when the system appears normal, making consistency checks critical for troubleshooting and O&amp;M.<br\/>Conclusion: True.<br\/>Option C: If Type 2 configurations of the two M-LAG member devices are inconsistent, the M-LAG running status may be abnormal. Compared with Type 1 configuration problems, Type 2 configuration problems are more likely to be detected and have less impact on the network.<br\/>Evaluation: This statement is true. Type 2 (common) configurations, such as QoS or STP settings, are less critical but can still affect network performance. According to Huawei M-LAG Best Practices, Type 2 inconsistencies are often detected during consistency checks but have a lower impact on M-LAG operation compared to Type 1 issues. They are also more likely to be flagged during monitoring, as they are less severe and easier to resolve.<br\/>Conclusion: True.<br\/>Option D: If Type 2 configurations of the two M-LAG member devices are inconsistent, an alarm that indicates key and common configuration inconsistencies is generated.<br\/>Evaluation: This statement is false. While Type 2 (common) configuration inconsistencies are detected during consistency checks, they do not typically trigger alarms, especially alarms that specifically indicate both key and common configuration inconsistencies. According to Huawei M-LAG Configuration Guide and Arista M-LAG Documentation, Type 2 inconsistencies may be logged or reported in system logs but are not severe enough to generate critical alarms unless they significantly impact network operation. Alarms are more commonly associated with Type 1 (key) configuration inconsistencies, as they pose a higher risk to M-LAG functionality.<br\/>Conclusion: False.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(17,this)' id='btn-17' value='See Answer'  \/><input type='hidden' id='questionType17' value='radio' class=''><\/div><div class='watu-question' id='question-18'><div class='question-content'><p><strong>NO.44<\/strong> Which of the following can be deployed to enhance DC reliability?

The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model: This is a possible cause. Some Huawei switch models (e.g., CE series) require a service loopback interface as the VTEP source IP. If omitted or misconfigured based on the model, external connectivity fails. POSSIBLE CAUSE.<br\/>C . No firewall security policy is configured when host traffic passes through the firewall: This is a possible cause. If a firewall is in the path (e.g., between tenant VPC and external network), a missing security policy (e.g., allowing outbound traffic) blocks access. POSSIBLE CAUSE.<br\/>D . The MAC address of the NVE interface on the VXLAN network is not manually specified: This is not a possible cause. The Network Virtualization Edge (NVE) interface in VXLAN does not require a manually specified MAC address; it uses the switch&#8217;s system MAC or auto-generates one. iMaster NCE-Fabric typically handles this automatically, and manual specification is neither required nor a common fault point for external access issues. NOT A POSSIBLE CAUSE.<br\/>Thus, D is not a possible cause of the fault.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(20,this)' id='btn-20' value='See Answer'  \/><input type='hidden' id='questionType20' value='radio' class=''><\/div><div class='watu-question' id='question-21'><div class='question-content'><p><strong>NO.47<\/strong> When an SDN controller cluster is deployed in Huawei CloudFabric Solution, which of the following network planes are divided based on carried services?

Let&#8217;s evaluate each statement:<br\/>A . A VXLAN tunnel endpoint that performs encapsulation is called a VNI: This is incorrect. A VXLAN Tunnel Endpoint (VTEP) is the device (physical or virtual) that performs encapsulation and decapsulation. The VNI (VXLAN Network Identifier) is a 24-bit field in the VXLAN header that identifies the virtual network, not the endpoint. FALSE.<br\/>B . VXLAN uses ECMP of the underlay network to improve network forwarding performance: Equal-Cost Multi-Path (ECMP) routing in the underlay network allows VXLAN to distribute traffic across multiple paths, enhancing load balancing and performance. This is a standard feature in Huawei&#8217;s VXLAN implementations. TRUE.<br\/>C . A VXLAN network is built based on UDP: VXLAN encapsulates Ethernet frames within UDP packets (using port 4789), making it a UDP-based overlay protocol. This is a core characteristic of VXLAN. TRUE.<br\/>D . VXLAN expands the number of subnets to 16 million and supports multi-tenancy: With a 24-bit VNI, VXLAN supports up to 16 million (2^24) unique network identifiers, enabling extensive subnet segmentation and multi-tenancy, a key advantage over traditional VLANs (4096 limit).

Its logical architecture consists of two primary modules:<br\/>VRM (Virtualization Resource Management): VRM is the management module responsible for centralized control, resource allocation, and monitoring of virtual machines, hosts, and clusters. It provides the user interface and orchestration capabilities for administrators to manage the virtualized environment.<br\/>CNA (Compute Node Agent): CNA runs on physical hosts and handles the execution of virtualization tasks, such as VM creation, resource scheduling, and communication with the underlying hypervisor (typically KVM in Huawei&#8217;s implementation). It acts as the compute node agent interfacing with the hardware.<br\/>Together, VRM and CNA form the core logical architecture of FusionCompute, with VRM managing the environment and CNA executing the compute tasks.
