問題 #59
In ZTP networking, which of the following addresses can be delivered by a DHCP server? (Select All that Apply)

A. Temporary management IP address
B. Default gateway address
C. SFTP server address
D. DNS server address

答案：A,B,D

解題說明：
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.

問題 #60
In EVPN, Type 5 routes are used only by hosts on a VXLAN network to access external networks.

A. FALSE
B. TRUE

答案：A

解題說明：
EVPN (Ethernet VPN) is a control plane technology used with VXLAN to provide Layer 2 and Layer 3 services in data center networks, including Huawei's implementations. EVPN routes are categorized into types, with Type 5 routes (IP Prefix routes) serving a specific purpose:
Type 5 Routes: These routes advertise IP prefixes and are used for inter-subnet routing, allowing communication between different VXLAN Virtual Network Identifiers (VNIs) or between VXLAN networks and external networks. They carry a Layer 3 VNI and IP prefix information, enabling routers or gateways to perform Layer 3 forwarding.
Usage Scope: Type 5 routes are not limited to hosts on a VXLAN network accessing external networks. They are also used by network devices (e.g., gateways, routers) within the EVPN domain to facilitate routing between subnets, including intra-VXLAN communication. For example, a centralized gateway or distributed gateway can use Type 5 routes to route traffic within the data center or to external networks, not just host-initiated access.
The statement is FALSE (B) because Type 5 routes are not exclusively for hosts on a VXLAN network to access external networks; they support broader Layer 3 routing functions across the EVPN domain.

問題 #61
Fill in blank
The FusionCompute logical architecture consists of two modules: ___ and CNA. (Enter the acronym in uppercase letters.)

答案：

解題說明：
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.

問題 #62
Which of the following statements are true about IP address planning for a DC? (Select All that Apply)

A. Service addresses refer to the IP addresses of servers, hosts, and gateways.
B. IP addresses must be contiguous. The routes with contiguous IP addresses can be summarized easily on a hierarchical network.
C. IP address allocation should be simple and easy to manage, reflect network layers, and simplify network management and network expansion.
D. IP addresses with a 24-bit mask are recommended for use as interconnection IP addresses.

答案：A,C

解題說明：
IP address planning is critical in Huawei's CloudFabric data center networks to ensure scalability and efficiency. Let's evaluate each statement:
A . Service addresses refer to the IP addresses of servers, hosts, and gateways: This is true. Service addresses are assigned to endpoints (servers, hosts) and gateways, distinguishing them from management or interconnection IPs in DC planning. TRUE.
B . IP addresses with a 24-bit mask are recommended for use as interconnection IP addresses: This is false. A 24-bit mask (/24) is typically used for service subnets, while interconnection IPs (e.g., between spine and leaf) often use smaller masks (e.g., /31 or /30) to conserve addresses and align with point-to-point links. FALSE.
C . IP addresses must be contiguous. The routes with contiguous IP addresses can be summarized easily on a hierarchical network: This is false. Contiguity is desirable for summarization but not mandatory; non-contiguous blocks can still be managed with proper routing design (e.g., using BGP). FALSE.
D . IP address allocation should be simple and easy to manage, reflect network layers, and simplify network management and network expansion: This is true. Huawei recommends structured allocation (e.g., by layer or function) to streamline management and support future growth. TRUE.
Thus, A and D are true statements about IP address planning.

問題 #63
Which of the following O&M functions are supported in Huawei CloudFabric Solution? (Select All that Apply)

A. Visualization of entries (MAC/IP) on logical routers and switches
B. Single-path detection
C. Network connectivity detection, such as IP ping and MAC ping
D. Multi-path detection

答案：A,C,D

解題說明：
Huawei's CloudFabric Solution, managed by iMaster NCE-Fabric, provides robust Operations and Maintenance (O&M) capabilities. Let's evaluate each option:
A . Multi-path detection: This is true. CloudFabric supports multi-path detection (e.g., using ECMP) to verify load balancing and path diversity in the network. TRUE.
B . Network connectivity detection, such as IP ping and MAC ping: This is true. Tools like IP ping and MAC ping are supported for troubleshooting connectivity between devices and endpoints. TRUE.
C . Single-path detection: This is false. While multi-path detection is supported, single-path detection is not a distinct O&M function; connectivity checks typically involve multiple paths or end-to-end verification. FALSE.
D . Visualization of entries (MAC/IP) on logical routers and switches: This is true. CloudFabric provides visualization of MAC and IP entries on logical network elements, aiding in network management and troubleshooting. TRUE.
Thus, A, B, and D are supported O&M functions.
