質問 # 37
BGP EVPN defines several types of BGP EVPN routes by extending BGP. Type ? routes are used to advertise host IP routes and external network routes. (Enter only digits.)
正解：
解説：
5
Explanation:
BGP EVPN (Ethernet VPN) extends BGP to provide control plane functionality for VXLAN overlays, including in Huawei's data center networks. EVPN defines several route types to advertise different types of information:
Type 1: Auto-discovery routes for EVPN instances.
Type 2: MAC/IP Advertisement routes for host reachability.
Type 3: Inclusive Multicast Ethernet Tag routes for multicast traffic.
Type 4: Ethernet Segment routes for multi-homing.
Type 5: IP Prefix routes for advertising host IP routes and external network routes, enabling inter-subnet and external connectivity.
The question specifies routes used to advertise "host IP routes and external network routes," which aligns with Type 5 routes. These routes carry IP prefix information and a Layer 3 VNI, facilitating Layer 3 routing within the EVPN domain or to external networks. Thus, the answer is 5.
質問 # 38
A VXLAN tunnel is identified by a pair of VTEP IP addresses. During VXLAN tunnel establishment, the local and remote VTEPs attempt to obtain each other's IP addresses. If the VTEP IP addresses are reachable to each other at Layer 3, a VXLAN tunnel can be established.
正解：B
解説：
VXLAN (Virtual Extensible LAN) tunnels are used to encapsulate Layer 2 traffic over a Layer 3 network, a key feature in Huawei's data center solutions. The endpoints of a VXLAN tunnel are VXLAN Tunnel Endpoints (VTEPs), identified by their IP addresses.
Tunnel Identification: A VXLAN tunnel is uniquely identified by the pair of VTEP IP addresses (local and remote), along with the VNI (VXLAN Network Identifier). This pair ensures the tunnel is specific to the communication path between the two VTEPs.
Tunnel Establishment: During setup, VTEPs exchange information to learn each other'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.
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. This is a fundamental requirement in Huawei's VXLAN implementation.
The statement is TRUE (A) because a VXLAN tunnel's identification and establishment depend on reachable VTEP IP address pairs at Layer 3.
質問 # 39
A tenant requires communication only within its own virtual network despite sharing the same VXLAN infrastructure with multiple business units. Which identifier uniquely distinguishes VXLAN segments?
正解：B
解説：
The VXLAN Network Identifier (VNI) provides up to approximately 16 million isolated Layer 2 segments. VLAN IDs are limited to 4094 usable values and therefore offer much smaller scalability than VXLAN VNIs.
質問 # 40
The FusionCompute logical architecture consists of two modules: ___ and CNA. (Enter the acronym in uppercase letters.)
正解：
解説：
VRM
Explanation:
FusionCompute is Huawei's virtualization platform, part of the FusionSphere ecosystem, designed for managing virtualized resources in data centers. Its logical architecture consists of two primary modules:
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.
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's implementation). It acts as the compute node agent interfacing with the hardware.
Together, VRM and CNA form the core logical architecture of FusionCompute, with VRM managing the environment and CNA executing the compute tasks. The answer, per Huawei's documentation, is VRM.
質問 # 41
A hypervisor virtualizes the following physical resources: memory, and input/output (I/O) resources. (Enter the acronym in uppercase letters.)
正解：
解説：
CPU
Explanation:
A hypervisor is a software layer that creates and manages virtual machines (VMs) by abstracting physical resources from the underlying hardware. The question specifies that the hypervisor virtualizes "memory" and "input/output (I/O) resources," and the task is to provide the missing resource acronym in uppercase letters. In virtualization contexts, including Huawei's FusionCompute or OpenStack with KVM, the primary physical resources virtualized by a hypervisor are:
CPU: The central processing unit (CPU) is virtualized to allocate processing power to VMs, enabling multi-tenancy and workload isolation.
Memory: Virtualized to provide RAM allocation to VMs, abstracted via memory management units (MMUs).
I/O Resources: Input/output resources (e.g., NICs, disks) are virtualized to allow VMs to communicate and store data, often through virtual NICs (vNICs) or virtual disks.
The question lists "memory" and "I/O resources" explicitly, implying the missing resource is CPU, as it completes the standard triad of virtualized resources in hypervisor design. Thus, the answer is CPU.
