Huawei HCIP-Data Center Network V1.0 Sample Questions (Q41-Q46):

NEW QUESTION # 41
Which of the following statements are true about IP address planning for a DC? (Select All that Apply)

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

Answer: B,C

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 # 42
In the computing scenario of Huawei CloudFabric Solution, which of the following services are optional for controller interconnection? (Select All that Apply)

A. Interconnection with the authentication server
B. Interconnection with the VMM
C. Interconnection with FabricInsight
D. Interconnection with eSight

Answer: C,D

Explanation:
In Huawei's CloudFabric Solution, the iMaster NCE-Fabric controller manages the network in computing scenarios (e.g., virtualized environments). Controller interconnection with external systems can be mandatory or optional depending on functionality. Let's evaluate each option:
A . Interconnection with FabricInsight: This is optional. FabricInsight is an analytics and assurance tool that enhances visibility and troubleshooting but is not required for basic controller operations in the computing scenario. OPTIONAL.
B . Interconnection with the authentication server: This is mandatory. Authentication servers (e.g., RADIUS, TACACS+) are essential for securing access to the controller and managed devices, a core requirement in computing scenarios. NOT OPTIONAL.
C . Interconnection with eSight: This is optional. eSight is a network management platform that provides additional monitoring and management capabilities, but it is not necessary for core controller functionality. OPTIONAL.
D . Interconnection with the VMM (Virtual Machine Manager): This is mandatory. Interconnection with a VMM (e.g., FusionCompute, OpenStack) is required to manage virtualized computing resources and orchestrate network services in the computing scenario. NOT OPTIONAL.
Thus, A (Interconnection with FabricInsight) and C (Interconnection with eSight) are optional services for controller interconnection.

NEW QUESTION # 43
Which of the following is not included in the physical architecture of a server?

A. OS
B. Hardware
C. VMmonitor
D. Application

Answer: D

Explanation:
The physical architecture of a server refers to the tangible and low-level components that constitute the server itself, distinct from logical or software layers. Let's evaluate each option:
A . Application: Applications are software running on top of an operating system or virtual machine, not part of the server's physical architecture. They belong to the logical or user layer, not the physical structure. Not Included.
B . VMmonitor (Hypervisor): Assuming "VMmonitor" refers to a hypervisor (e.g., KVM or Xen), it's a software layer, but in Type-1 hypervisor scenarios, it runs directly on hardware, managing VMs. In Huawei's context, it's considered part of the server's operational architecture when deployed physically. Included.
C . OS (Operating System): The OS (e.g., Linux, Windows) runs directly on server hardware or within a VM. In bare-metal servers, it's a core component of the physical deployment. Included.
D . Hardware: Hardware (e.g., CPU, RAM, NICs, disks) is the foundational physical architecture of a server, providing the physical resources for all operations. Included.
Thus, A (Application) is not part of the physical architecture, as it's a higher-level software entity, not a physical component.

NEW QUESTION # 44
A hypervisor virtualizes the following physical resources: memory, and input/output (I/O) resources. (Enter the acronym in uppercase letters.)

Answer:

Explanation:
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.

NEW QUESTION # 45
Which of the following O&M functions are supported in Huawei CloudFabric Solution? (Select All that Apply)

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

Answer: A,B,C

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.
