iMaster NCE-FabricInsight uses telemetry for performance metric collection, offering advanced monitoring in Huawei's CloudFabric Solution. Let's evaluate each option:

A . Efficient transmission: This is true. Telemetry uses streaming data (e.g., gRPC) to reduce overhead compared to traditional polling, enabling efficient transmission of metrics. TRUE.

B . Quasi-real-time data collection: This is true. Telemetry provides near-real-time data (e.g., sub-second updates), improving responsiveness over periodic SNMP polling. TRUE.

C . Intelligent data analysis and automated troubleshooting: This is false. While FabricInsight performs intelligent analysis, automated troubleshooting is a feature of the broader iMaster NCE platform, not specifically a telemetry advantage. Telemetry enables data collection, not the automation itself. FALSE.

D . One-off subscription and continuous data push: This is true. Telemetry operates on a subscription model where a one-time setup leads to continuous data push from devices, reducing manual intervention. TRUE.

Thus, A, B, and D are advantages of telemetry-based performance metric collection.

Huawei's iMaster NCE-Fabric is an SDN controller for the CloudFabric Solution, providing network orchestration and management. It includes built-in servers to support its operations. Let's evaluate each option:

A . DNS server: This is false. iMaster NCE-Fabric does not include a built-in DNS server; it relies on external DNS services for name resolution, configured during deployment. FALSE.

B . RADIUS authentication server: This is false. RADIUS authentication is typically handled by external AAA servers; iMaster NCE-Fabric integrates with them but does not embed a RADIUS server. FALSE.

C . DHCP server: This is true. iMaster NCE-Fabric includes a built-in DHCP server to assign temporary IP addresses during Zero Touch Provisioning (ZTP) or initial device configuration. TRUE.

D . Version file server: This is true. A version file server is built into iMaster NCE-Fabric to store and deliver software images or configuration files for device upgrades and management. TRUE.

Thus, C (DHCP server) and D (Version file server) are built into iMaster NCE-Fabric.

Reliability in Huawei's CloudFabric data centers is enhanced through various mechanisms. Let's evaluate each option:

A . Power supply redundancy: This is true. Redundant power supplies (e.g., dual PSUs) ensure uninterrupted operation during power failures, a key reliability feature. TRUE.

B . M-LAG (Multi-Chassis Link Aggregation): This is true. M-LAG provides high availability by allowing active-active forwarding and failover between switches, enhancing network reliability. TRUE.

C . Monitor Link: This is false. Monitor Link is a Huawei feature for link status monitoring, not a direct reliability enhancement mechanism like redundancy or clustering. FALSE.

D . Controller cluster: This is true. A clustered SDN controller (e.g., iMaster NCE-Fabric) ensures high availability and failover, improving network management reliability. TRUE.

Thus, A, B, and D enhance DC reliability.

Microsegmentation in Huawei's data center networks (e.g., CloudFabric with SDN) divides Endpoint Groups (EPGs) to enforce fine-grained security policies. EPGs group endpoints (e.g., VMs) based on attributes. Let's evaluate each option:

A . Operating system: This is true. The OS type (e.g., Linux, Windows) can be used to segment EPGs, enabling policy enforcement based on OS-specific security needs. TRUE.

B . VM name: This is true. VM names can be used as identifiers for microsegmentation, allowing policies to target specific VMs. TRUE.

C . IP address: This is true. IP addresses are commonly used to define EPG boundaries, especially for network-based segmentation. TRUE.

D . MAC address: This is true. MAC addresses can segment EPGs, particularly for Layer 2-based policies or device-specific isolation. TRUE.

All options A, B, C, and D are valid conditions for microsegmentation to divide EPGs in Huawei's implementation.

OSPF (Open Shortest Path First) is a routing protocol used in the underlay network of Huawei's CloudFabric DCNs. Let's evaluate each statement:

A . Typically, the IP address of Loopback0 is configured as the VTEP IP address and the same IP address is planned for active-active leaf nodes in the same group: This is true. Loopback0 IP is commonly used as the VTEP IP for stability, and in active-active leaf node groups (e.g., M-LAG), the same IP can be configured with VRRP or anycast to ensure consistency. TRUE.

B . The network type of spine and leaf nodes can be set to P2P in order to accelerate convergence: This is true. Setting OSPF network type to Point-to-Point (P2P) on spine-leaf links reduces overhead (e.g., no DR/BDR election) and speeds up convergence, a recommended practice in Huawei DCNs. TRUE.

C . This routing design is recommended when the DC has more than 300 switches: This is false. OSPF is suitable for smaller to medium-sized DCNs (e.g., up to 200-300 switches). For larger networks (>300 switches), EBGP is preferred due to better scalability and reduced complexity. FALSE.

D . It is recommended that all devices be planned in Area 0: This is false. While a single Area 0 is possible for small DCNs, multi-area OSPF is recommended for larger networks to manage scalability and reduce routing table size, avoiding a flat Area 0 design. FALSE.

Thus, A and B are true statements about OSPF routing design in a DC underlay.

In Huawei's CloudFabric Solution, SecoManager (Security Manager) and iMaster NCE-Fabric (Network Controller) are components of the SDN ecosystem. SecoManager handles security policy management, while iMaster NCE-Fabric manages network orchestration.

Deployment: These components can be deployed independently but are designed to integrate seamlessly. Huawei's architecture supports automated interconnection after installation, leveraging northbound/southbound APIs or pre-configured integration workflows.

Interconnection: Manual interconnection is not required post-installation; the system automates the process once both are deployed and configured within the same management domain (e.g., via IP addressing and authentication).

The statement is FALSE (B) because interconnection is automated, not manual.

On Huawei CloudEngine (CE) series switches, VXLAN tunnel monitoring and troubleshooting involve specific commands to diagnose issues such as tunnel Down status or failed dynamic establishment. Let's evaluate each option:

A . Run the display vxlan statistics command to check the cause of the fault: This command provides statistics on VXLAN tunnel traffic, including packet drops, encapsulation/decapsulation counts, and errors. It helps identify issues like misconfiguration or network congestion, making it a valid troubleshooting tool. TRUE.

B . Run the display vxlan peer command to check the cause of the fault on the peer device of the tunnel: This command displays information about VXLAN peers, including their IP addresses, VNIs, and reachability status. Checking the peer device's status can reveal connectivity or configuration mismatches, aiding fault diagnosis. TRUE.

C . Run the display vxlan troubleshooting command to check the causes of at most the latest five failures to dynamically establish a VXLAN tunnel: This command logs and displays troubleshooting details, including the latest five failure reasons for dynamic tunnel setup (e.g., BGP EVPN issues or reachability problems). This is a standard feature on Huawei CE switches. TRUE.

D . Run the display vxlan troubleshooting command to check at most the latest five reasons why a VXLAN tunnel goes Down: This command also tracks reasons for tunnel Down events (e.g., underlay failure, peer unreachability), limited to the latest five incidents. This is consistent with Huawei's troubleshooting capabilities. TRUE.

All options A, B, C, and D are true, as they represent valid commands and approaches to troubleshoot VXLAN tunnel issues on Huawei CE switches.
