質問 # 21
Linux consists of the user space and kernel space. Which of the following functions are included in the kernel space? (Select All that Apply)
正解：A、B、D
解説：
In Linux, the operating system is divided into user space (where applications run) and kernel space (where the OS core functions execute with privileged access to hardware). Let's evaluate each function:
A . The NIC Driver Sends Data Frames: Network Interface Card (NIC) drivers operate in kernel space, managing hardware interactions like sending and receiving data frames. This is a low-level task requiring direct hardware access, handled by the kernel's network stack. Included in Kernel Space.
B . Data Encapsulation: Data encapsulation (e.g., adding headers in the TCP/IP stack) occurs in the kernel's network subsystem (e.g., via the protocol stack like IP or TCP). This process prepares packets for transmission and is a kernel-space function. Included in Kernel Space.
C . Bit Stream Transmission: This refers to the physical transmission of bits over the network, managed by the NIC hardware and its driver in kernel space. The kernel coordinates with the NIC to send bit streams, making this a kernel-space function. Included in Kernel Space.
D . Data Encryption: Encryption (e.g., via OpenSSL or application-level VPNs) typically occurs in user space, where applications or libraries handle cryptographic operations. While the kernel supports encryption (e.g., IPsec in the network stack), the actual encryption logic is often offloaded to user-space tools, not a core kernel function in standard contexts. Not Typically in Kernel Space.
Thus, A, B, and C are functions included in the kernel space, aligning with Linux architecture in Huawei's DCN context.
質問 # 22
The figure shows an incomplete VXLAN packet format.
Which of the following positions should the VXLAN header be inserted into so that the packet format is complete?
正解：C
解説：
VXLAN (Virtual Extensible LAN) is a tunneling protocol that encapsulates Layer 2 Ethernet frames within UDP packets to extend VLANs across Layer 3 networks, commonly used in Huawei's CloudFabric data center solutions. The provided figure illustrates an incomplete VXLAN packet format with the following sequence:
Outer Ethernet Header (Position 1): Encapsulates the packet for transport over the physical network.
Outer IP Header (Position 2): Defines the source and destination IP addresses for the tunnel endpoints.
UDP Header (Position 3): Carries the VXLAN traffic over UDP port 4789.
Inner Ethernet Header (Position 4): The original Layer 2 frame from the VM or endpoint.
Inner IP Header (Position 5): The original IP header of the encapsulated payload.
Payload (Position 6): The data being transported.
The VXLAN header, which includes a 24-bit VXLAN Network Identifier (VNI) to identify the virtual network, must be inserted to complete the encapsulation. In a standard VXLAN packet format:
The VXLAN header follows the UDP header and precedes the inner Ethernet header. This is because the VXLAN header is part of the encapsulation layer, providing the VNI to map the inner frame to the correct overlay network.
The sequence is: Outer Ethernet Header → Outer IP Header → UDP Header → VXLAN Header → Inner Ethernet Header → Inner IP Header → Payload.
In the figure, the positions are numbered as follows:
1: Outer Ethernet Header
2: Outer IP Header
3: UDP Header
4: Inner Ethernet Header
The VXLAN header should be inserted after the UDP header (Position 3) and before the Inner Ethernet Header (Position 4). However, the question asks for the position where the VXLAN header should be "inserted into," implying the point of insertion relative to the existing headers. Since the inner Ethernet header (Position 4) is where the encapsulated data begins, the VXLAN header must be placed just before it, which corresponds to inserting it at the transition from the UDP header to the inner headers. Thus, the correct position is D (2) if interpreted as the logical insertion point after the UDP header, but based on the numbering, it aligns with the need to place it before Position 4. Correcting for the figure's intent, the VXLAN header insertion logically occurs at the boundary before Position 4, but the options suggest a mislabeling. Given standard VXLAN documentation, the VXLAN header follows UDP (Position 3), and the closest insertion point before the inner headers is misinterpreted in numbering. Re-evaluating the figure, Position 2 (after Outer IP Header) is incorrect, and Position 3 (after UDP) is not listed separately. The correct technical insertion is after UDP, but the best fit per options is D (2) as a misnumbered reference to the UDP-to-inner transition. However, standard correction yields after UDP (not directly an option), but strictly, it's after 3. Given options, D (2) is the intended answer based on misaligned numbering.
Corrected answer: After re-evaluating the standard VXLAN packet structure and the figure's
質問 # 23
Which of the following components is not required to provide necessary computing, storage, and network resources for VMs during VM creation?
正解：C
解説：
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.
質問 # 24
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)
正解：A、D
解説：
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.
質問 # 25
In the VPC interworking scenario, traffic is checked and filtered only by the firewall in the source or destination VPC.
正解：B
解説：
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.
