VXLAN, M-LAG, and CloudFabric Deployment typically account for 40-50% of exam questions. These technologies are central to modern Huawei data center solutions. However, all eight topics are important; gaps in foundational knowledge or O&M skills can cost you points even if you excel in the major areas.
During planning, you choose between VXLAN multicast and unicast modes based on network topology and business needs. Deployment applies M-LAG for redundancy and CloudFabric for orchestration, while virtualization principles guide how you segment workloads. Operations then monitors these technologies daily, troubleshoots faults, and manages upgrades. Understanding these connections helps you answer scenario questions more confidently.
Hands-on experience is valuable but not required to pass. Prioritize labs that let you configure VXLAN tunnels, set up M-LAG peer links, and deploy a small CloudFabric fabric. If you lack access to real hardware, detailed technical documentation and simulation tools can fill the gap. Focus on understanding the "why" behind each configuration step rather than memorizing commands.
Common errors include confusing VXLAN multicast and unicast modes, misunderstanding M-LAG peer link requirements, and overlooking O&M considerations during the planning phase. Many candidates also rush through scenario questions without fully analyzing the constraints. Take time to read each question carefully, identify what is being asked, and eliminate clearly wrong answers before selecting your response.
In the final week, shift from learning new material to reinforcing weak areas and building test-taking confidence. Review your practice test results, re-read explanations for questions you missed, and do a final full-length timed test. Avoid cramming new topics; instead, focus on scenario-based questions and ensure you understand the reasoning behind each correct answer. Get adequate sleep the night before your exam.
Which of the following technologies are open-source virtualization technologies? (Select All that Apply)
Virtualization technologies enable the creation of virtual machines (VMs) by abstracting hardware resources. Open-source technologies are freely available with accessible source code. Let's evaluate each option:
A . Hyper-V: Hyper-V is a hypervisor developed by Microsoft, integrated into Windows Server and available as a standalone product. It is proprietary, not open-source, as its source code is not publicly available. Not Open-Source.
B . Xen: Xen is an open-source hypervisor maintained by the Xen Project under the Linux Foundation. It supports multiple guest operating systems and is widely used in cloud environments (e.g., Citrix XenServer builds on it). Its source code is freely available. Open-Source.
C . FusionSphere: FusionSphere is Huawei's proprietary virtualization and cloud computing platform, based on OpenStack and other components. While it integrates open-source elements (e.g., KVM), FusionSphere itself is a commercial product, not fully open-source. Not Open-Source.
D . KVM (Kernel-based Virtual Machine): KVM is an open-source virtualization technology integrated into the Linux kernel. It turns Linux into a Type-1 hypervisor, and its source code is available under the GNU General Public License. It's widely used in Huawei's virtualization solutions. Open-Source.
Thus, B (Xen) and D (KVM) are open-source virtualization technologies.
To allow access to a VXLAN network, you need to configure service access points on devices. There are two access modes: Layer ? sub-interface and binding. (Enter the acronym in uppercase letters.)
VXLAN (Virtual Extensible LAN) is a network overlay technology that extends Layer 2 networks over a Layer 3 underlay, commonly implemented in Huawei's CloudFabric data center solutions. To enable access to a VXLAN network, service access points (e.g., interfaces or sub-interfaces) must be configured on devices such as switches or routers acting as VXLAN Tunnel Endpoints (VTEPs). The question mentions two access modes: 'Layer ? sub-interface' and 'binding,' with the task to fill in the layer acronym in uppercase letters.
Context Analysis: The missing layer is indicated by a '?' and is part of a sub-interface configuration. In networking, sub-interfaces are typically associated with Layer 3 (e.g., for VLAN tagging or VXLAN integration), where they handle IP routing or mapping to overlay networks.
Access Modes:
Layer 3 Sub-Interface: This mode involves configuring a sub-interface on a Layer 3 device (e.g., a router or Layer 3 switch) to terminate VXLAN tunnels and perform routing. The sub-interface is associated with a VNI (VXLAN Network Identifier) and often uses a Layer 3 protocol (e.g., BGP EVPN) to connect to the VXLAN overlay.
Binding: This likely refers to binding a VNI to a Bridge Domain (BD) or interface, a common practice in Huawei's VXLAN configuration to map the overlay network to a physical or logical port. This can occur at Layer 2 or Layer 3, but the sub-interface context suggests Layer 3 involvement.
The question's structure implies the layer number for the sub-interface mode, which is Layer 3 in VXLAN contexts for routing and gateway functions. Thus, the acronym (digit) to enter is 3.
Which of the following operations need to be performed before deployment in Easy mode? (Select All that Apply)
The Easy mode in Huawei's iMaster NCE-Fabric simplifies VXLAN fabric deployment with automated configuration. Certain pre-deployment steps are required. Let's evaluate each option:
A . Disable data synchronization upon going online for the first time: This is false. Data synchronization is typically enabled by default to ensure consistency; disabling it is not a standard pre-deployment step and is optional based on specific needs. FALSE.
B . Load the license: This is true. A valid license must be loaded into iMaster NCE-Fabric before deployment to unlock features, including Easy mode functionality. TRUE.
C . Pre-configure the access ports: This is true. Access ports on devices (e.g., server leaf nodes) need to be pre-configured (e.g., with VLANs or basic settings) to ensure connectivity before Easy mode automation begins. TRUE.
D . Configure an SSH fingerprint verification policy: This is false. SSH fingerprint verification is part of security configuration but is not a mandatory pre-deployment step for Easy mode; it can be set post-deployment or is automated. FALSE.
Thus, B (Load the license) and C (Pre-configure the access ports) are required operations before deployment in Easy mode.
Which of the following statements is false about M-LAG deployment?
M-LAG (Multi-Chassis Link Aggregation) on Huawei CE series switches enhances high availability and load balancing by making two switches appear as one. Let's evaluate each statement:
A . Multi-level M-LAG is mainly used to construct a large Layer 2 network in a DCN or directly connect DCNs at Layer 2: This is true. Multi-level M-LAG extends the topology across multiple layers or data centers, facilitating large Layer 2 domains, a common use case in Huawei DCNs. TRUE.
B . In multi-level M-LAG networking, you can manually configure the root bridge to prevent STP loops: This is true. Manual configuration of the root bridge (e.g., using STP priority) is supported to optimize path selection and prevent loops, especially in complex M-LAG setups. TRUE.
C . Multi-level M-LAG must be configured based on V-STP: This is false. While V-STP can be used to prevent loops, M-LAG does not require V-STP specifically. Standard STP, RSTP, or MSTP can also be configured, depending on the network design. The requirement is loop prevention, not a mandatory V-STP dependency. FALSE.
D . M-LAG networking can be classified into single-level M-LAG networking and multi-level M-LAG networking: This is true. Single-level M-LAG connects two switches directly to devices, while multi-level M-LAG extends across additional layers or devices, a recognized classification in Huawei documentation. TRUE.
Thus, C is the false statement because multi-level M-LAG does not mandate V-STP configuration.
Which of the following servers are built into iMaster NCE-Fabric to provide related services? (Select All that Apply)
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.
