질문 # 75
In the VPC interworking scenario, traffic is checked and filtered only by the firewall in the source or destination VPC.

정답：B

설명：
In Huawei's CloudFabric Solution, Virtual Private Clouds (VPCs) enable isolated network environments, and interworking scenarios involve traffic between VPCs. The statement claims that traffic is checked and filtered only by the firewall in the source or destination VPC. Let's evaluate:
VPC Interworking: Traffic between VPCs can be routed via a gateway (e.g., a Layer 3 gateway or centralized router) and may involve multiple security checkpoints depending on the design.
Firewalls can be deployed in the source VPC, destination VPC, or a centralized location (e.g., a service chain or border gateway).
Firewall Role: The statement implies exclusivity (only one firewall), but in practice, traffic may be filtered by firewalls at both ends, a centralized firewall, or additional security devices (e.g., VAS nodes) in the path. For example, inter-VPC traffic might pass through a firewall in the source VPC for egress filtering and another in the destination VPC for ingress filtering, or a shared firewall in a hub- and-spoke model. Huawei's security architecture (e.g., with SecoManager) supports distributed or centralized filtering, not limited to a single VPC's firewall.
The statement is FALSE (B) because traffic is not restricted to being checked and filtered only by the firewall in the source or destination VPC; multiple firewalls or security devices may be involved.


질문 # 76
In the DCN architecture, spine nodes connect various network devices to the VXLAN network.

정답：A

설명：
In Huawei's Data Center Network (DCN) architecture, particularly with the CloudFabric solution, the spine-leaf topology is a common design for scalable and efficient data centers. VXLAN (Virtual Extensible LAN) is used to create overlay networks, enabling large-scale multi-tenancy and flexible workload placement.
Spine Nodes' Role: In this architecture, spine nodes act as the backbone, interconnecting leaf nodes (which connect to servers, storage, or other endpoints) and facilitating high-speed, non-blocking communication. Spine nodes typically handle Layer 3 routing and serve as VXLAN tunnel endpoints (VTEPs) or connect to devices that do, integrating the physical underlay with the VXLAN overlay network.
Connection to VXLAN: Spine nodes ensure that traffic from various network devices (via leaf nodes) is routed efficiently across the VXLAN fabric. They provide the high-bandwidth, low-latency backbone required for east-west traffic in modern data centers, supporting VXLAN encapsulation and decapsulation indirectly or directly depending on the deployment.
Thus, the statement is TRUE (A) because spine nodes play a critical role in connecting the underlay network (various devices via leaf nodes) to the VXLAN overlay, as per Huawei's DCN design principles.


질문 # 77
Which underlay characteristic is most important for ensuring reliable VXLAN overlay communication across a spine-leaf fabric?

정답：D

설명：
VXLAN relies entirely on an IP underlay. Every VTEP must reach every other VTEP through stable IP routing. Layer 2 mechanisms such as STP or native VLAN settings are not primary overlay requirements.


질문 # 78
Which of the following statements are true about IP address planning for a DC? (Select All that Apply)

정답：A,D

설명：
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.


질문 # 79
Which of the following statements are true about a routing design that employs OSPF on the underlay network of a DC? (Select All that Apply)

정답：B,C

설명：
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.
