Which of the following statements are true about the Easy mode? (Select All that Apply)
Answer : A, B, D
The Easy mode in Huawei's iMaster NCE-Fabric simplifies network deployment for basic VXLAN fabrics. Let's evaluate each statement:
A . This mode has low networking requirements: This is true. Easy mode is designed for simple topologies (e.g., small spine-leaf networks) with minimal configuration complexity. TRUE.
B . iMaster NCE-Fabric automatically generates configuration script files: This is true. Easy mode automates script generation based on user inputs, reducing manual effort. TRUE.
C . On iMaster NCE-Fabric, you need to manually create and configure fabric resource pools, managed devices, device groups, device roles, tenants, and VPCs one by one in the Configuration Wizard menu: This is false. Easy mode automates these tasks, minimizing manual configuration compared to advanced modes. FALSE.
D . Layer 2 and Layer 3 basic services in a VPC are orchestrated on the Easy page: This is true. Easy mode supports automated orchestration of L2 (e.g., BDs) and L3 (e.g., gateways) services within a VPC. TRUE.
Thus, A, B, and D are true statements about Easy mode.
When an SDN controller cluster is deployed in Huawei CloudFabric Solution, which of the following network planes are divided based on carried services? (Select All that Apply)
Answer : B, C, D
In Huawei's CloudFabric Solution, the iMaster NCE-Fabric SDN controller cluster separates network planes based on carried services to ensure scalability and security. Let's evaluate each option:
A . BGP microservice plane: This is not a standard plane in Huawei's SDN architecture. BGP is used in the underlay/overlay but not defined as a separate microservice plane for the controller. FALSE.
B . Southbound service plane: This is true. The southbound plane carries configuration and control data to network devices (e.g., via NETCONF, BGP-EVPN), a critical service plane in SDN. TRUE.
C . Northbound management plane: This is true. The northbound plane provides APIs for management applications and orchestration (e.g., OpenStack integration), handling service requests. TRUE.
D . Internal communication plane: This is true. This plane facilitates communication between controller cluster nodes for synchronization and high availability. TRUE.
Thus, B (Southbound service plane), C (Northbound management plane), and D (Internal communication plane) are the network planes divided based on carried services.
Which of the following nodes connects computing resources such as virtual and physical servers to a VXLAN fabric?
Answer : B
In Huawei's spine-leaf VXLAN fabric (e.g., CloudFabric), nodes have specific roles:
A . DCI leaf: Data Center Interconnect (DCI) leaf nodes connect different data centers, not internal computing resources. Incorrect.
B . Server leaf: Server leaf nodes connect computing resources (virtual servers via hypervisors, physical servers) to the VXLAN fabric, handling access traffic. This is the correct role for connecting servers. Correct.
C . Border leaf: Border leaf nodes connect the DCN to external networks, not internal computing resources. Incorrect.
D . Service leaf: Service leaf nodes connect to value-added services (e.g., firewalls), not directly to computing resources like servers. Incorrect.
Thus, the answer is B (Server leaf).
Which of the following technologies are open-source virtualization technologies? (Select All that Apply)
Answer : B, D
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.
In the CloudFabric Solution, SecoManager and iMaster NCE-Fabric are deployed independently. After SecoManager is installed, it needs to be manually interconnected with iMaster NCE-Fabric.
Answer : B
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.
Which of the following components is not required to provide necessary computing, storage, and network resources for VMs during VM creation?
Answer : C
This question pertains to OpenStack, a common virtualization platform in Huawei's HCIP-Data Center Network curriculum, where components collaborate to create and manage virtual machines (VMs). Let's analyze each component's role in providing computing, storage, and network resources during VM creation:
A . Nova: Nova is the compute service in OpenStack, responsible for managing VM lifecycles, including provisioning CPU and memory resources. It's essential for providing computing resources during VM creation. Required.
B . Neutron: Neutron is the networking service, handling virtual network creation, IP allocation, and connectivity (e.g., VXLAN or VLAN) for VMs. It's critical for providing network resources during VM creation. Required.
C . Ceilometer: Ceilometer is the telemetry service, used for monitoring, metering, and collecting usage data (e.g., CPU utilization, disk I/O) of VMs. While useful for billing or optimization, it does not directly provide computing, storage, or network resources during VM creation. Not Required.
D . Cinder: Cinder is the block storage service, providing persistent storage volumes for VMs (e.g., for OS disks or data). It's essential for providing storage resources during VM creation if a volume is attached. Required.
Thus, C (Ceilometer) is not required to provision the core resources (computing, storage, network) for VM creation, as its role is monitoring, not resource allocation.
In ZTP networking, which of the following addresses can be delivered by a DHCP server? (Select All that Apply)
Answer : A, C, D
Zero Touch Provisioning (ZTP) in Huawei's CloudFabric automates device setup using DHCP. Let's evaluate each option:
A . Default gateway address: This is true. DHCP can deliver the default gateway address to configure routing for the device. TRUE.
B . SFTP server address: This is false. SFTP server addresses are not standard DHCP options; they may be configured manually or via other protocols (e.g., TFTP for boot files). FALSE.
C . DNS server address: This is true. DHCP can provide DNS server addresses (Option 6) for name resolution during ZTP. TRUE.
D . Temporary management IP address: This is true. DHCP assigns temporary IPs (e.g., Option 50) for management during initial provisioning in ZTP. TRUE.
Thus, A, C, and D can be delivered by a DHCP server in ZTP.
