Huawei HCIP-Data Center Network V1.0 Sample Questions (Q11-Q16):

NEW QUESTION # 11
Which of the following statements is false about M-LAG deployment?

  • A. M-LAG networking can be classified into single-level M-LAG networking and multi-level M-LAG networking.
  • B. In multi-level M-LAG networking, you can manually configure the root bridge to prevent STP loops.
  • C. Multi-level M-LAG must be configured based on V-STP.
  • D. Multi-level M-LAG is mainly used to construct a large Layer 2 network in a DCN or directly connect DCNs at Layer 2.

Answer: C

Explanation:
M-LAG (Multi-Chassis Link Aggregation) on Huawei CE series switches enhances high availability and load balancing by making two switches appear as one. Let's evaluate each statement:
A . Multi-level M-LAG is mainly used to construct a large Layer 2 network in a DCN or directly connect DCNs at Layer 2: This is true. Multi-level M-LAG extends the topology across multiple layers or data centers, facilitating large Layer 2 domains, a common use case in Huawei DCNs. TRUE.
B . In multi-level M-LAG networking, you can manually configure the root bridge to prevent STP loops: This is true. Manual configuration of the root bridge (e.g., using STP priority) is supported to optimize path selection and prevent loops, especially in complex M-LAG setups. TRUE.
C . Multi-level M-LAG must be configured based on V-STP: This is false. While V-STP can be used to prevent loops, M-LAG does not require V-STP specifically. Standard STP, RSTP, or MSTP can also be configured, depending on the network design. The requirement is loop prevention, not a mandatory V-STP dependency. FALSE.
D . M-LAG networking can be classified into single-level M-LAG networking and multi-level M-LAG networking: This is true. Single-level M-LAG connects two switches directly to devices, while multi-level M-LAG extends across additional layers or devices, a recognized classification in Huawei documentation. TRUE.
Thus, C is the false statement because multi-level M-LAG does not mandate V-STP configuration.


NEW QUESTION # 12
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 with a 24-bit mask are recommended for use as interconnection IP addresses.
  • C. IP addresses must be contiguous. The routes with contiguous IP addresses can be summarized easily on a hierarchical network.
  • D. IP address allocation should be simple and easy to manage, reflect network layers, and simplify network management and network expansion.

Answer: A,D

Explanation:
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.


NEW QUESTION # 13
In EVPN, Type 5 routes are used only by hosts on a VXLAN network to access external networks.

  • A. FALSE
  • B. TRUE

Answer: A

Explanation:
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.


NEW QUESTION # 14
Which of the following is not an advantage of link aggregation on CE series switches?

  • A. Increased bandwidth
  • B. Load balancing supported
  • C. Improved forwarding performance of switches
  • D. Improved reliability

Answer: C

Explanation:
Link aggregation, often implemented using Link Aggregation Control Protocol (LACP) on Huawei CloudEngine (CE) series switches, combines multiple physical links into a single logical link to enhance network performance and resilience. The primary advantages include:
Load Balancing Supported (B): Link aggregation distributes traffic across multiple links based on hashing algorithms (e.g., source/destination IP or MAC), improving load distribution and preventing any single link from becoming a bottleneck.
Increased Bandwidth (C): By aggregating multiple links (e.g., 1 Gbps ports into a 4 Gbps logical link), the total available bandwidth increases proportionally to the number of links.
Improved Reliability (D): If one link fails, traffic is automatically redistributed to the remaining links, ensuring continuous connectivity and high availability.
However, Improved Forwarding Performance of Switches (A) is not a direct advantage. Forwarding performance relates to the switch's internal packet processing capabilities (e.g., ASIC performance, forwarding table size), which link aggregation does not inherently enhance. While it optimizes link utilization, it doesn't improve the switch's intrinsic forwarding rate or reduce latency at the hardware level. This aligns with Huawei's CE series switch documentation, where link aggregation is described as enhancing bandwidth and reliability, not the switch's core forwarding engine.


NEW QUESTION # 15
Which of the following O&M functions are supported in Huawei CloudFabric Solution? (Select All that Apply)

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

Answer: A,B,D

Explanation:
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.
