Huawei HCIP-Data Center Network V1.0 Sample Questions (Q41-Q46):
NEW QUESTION # 41
In the VPC interworking scenario, traffic is checked and filtered only by the firewall in the source or destination VPC.
Answer: A
Explanation:
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.
NEW QUESTION # 42
Which of the following statements are true about the Easy mode? (Select All that Apply)
Answer: A,C,D
Explanation:
The Easy mode in Huawei's iMaster NCE-Fabric simplifies network deployment for basic VXLAN fabrics. Let's evaluate each statement:
A . This mode has low networking requirements: This is true. Easy mode is designed for simple topologies (e.g., small spine-leaf networks) with minimal configuration complexity. TRUE.
B . iMaster NCE-Fabric automatically generates configuration script files: This is true. Easy mode automates script generation based on user inputs, reducing manual effort. TRUE.
C . On iMaster NCE-Fabric, you need to manually create and configure fabric resource pools, managed devices, device groups, device roles, tenants, and VPCs one by one in the Configuration Wizard menu: This is false. Easy mode automates these tasks, minimizing manual configuration compared to advanced modes. FALSE.
D . Layer 2 and Layer 3 basic services in a VPC are orchestrated on the Easy page: This is true. Easy mode supports automated orchestration of L2 (e.g., BDs) and L3 (e.g., gateways) services within a VPC. TRUE.
Thus, A, B, and D are true statements about Easy mode.
NEW QUESTION # 43
Which of the following statements are false about heartbeat link faults in an M-LAG? (Select All that Apply)
Answer: A,D
Explanation:
In Huawei's M-LAG (Multi-Chassis Link Aggregation), the heartbeat link (or peer-link) ensures communication between member devices. A fault in this link can impact M-LAG operation. Let's evaluate each statement:
A . The fault that two master devices exist cannot be detected in the case of a peer-link fault: This is false. A peer-link fault can be detected, and mechanisms like dual-master detection (e.g., via Inter-Chassis Communication Link or ICC) can identify if both devices assume master roles, triggering corrective actions. FALSE.
B . An alarm is triggered: This is true. A peer-link fault generates an alarm to notify administrators, as it's a critical failure in M-LAG operation, per Huawei's fault management system. TRUE.
C . The fault protection mechanism is triggered: This is true. Huawei M-LAG includes protection mechanisms (e.g., failover to backup links or shutdown of conflicting interfaces) to mitigate peer-link faults and maintain service continuity. TRUE.
D . Services are affected: This is false. With proper configuration (e.g., redundant links or fast failover), services should not be affected by a peer-link fault, as M-LAG is designed for high availability. Impact depends on redundancy, but the design goal is uninterrupted service. FALSE.
Thus, A and D are false statements because dual-master faults can be detected, and services are not necessarily affected with adequate redundancy.
NEW QUESTION # 44
To allow access to a VXLAN network, you need to configure service access points on devices. There are two access modes: Layer ? sub-interface and binding. (Enter the acronym in uppercase letters.)
Answer:
Explanation:
3
Explanation:
VXLAN (Virtual Extensible LAN) is a network overlay technology that extends Layer 2 networks over a Layer 3 underlay, commonly implemented in Huawei's CloudFabric data center solutions. To enable access to a VXLAN network, service access points (e.g., interfaces or sub-interfaces) must be configured on devices such as switches or routers acting as VXLAN Tunnel Endpoints (VTEPs). The question mentions two access modes: "Layer ? sub-interface" and "binding," with the task to fill in the layer acronym in uppercase letters.
Context Analysis: The missing layer is indicated by a "?" and is part of a sub-interface configuration. In networking, sub-interfaces are typically associated with Layer 3 (e.g., for VLAN tagging or VXLAN integration), where they handle IP routing or mapping to overlay networks.
Access Modes:
Layer 3 Sub-Interface: This mode involves configuring a sub-interface on a Layer 3 device (e.g., a router or Layer 3 switch) to terminate VXLAN tunnels and perform routing. The sub-interface is associated with a VNI (VXLAN Network Identifier) and often uses a Layer 3 protocol (e.g., BGP EVPN) to connect to the VXLAN overlay.
Binding: This likely refers to binding a VNI to a Bridge Domain (BD) or interface, a common practice in Huawei's VXLAN configuration to map the overlay network to a physical or logical port. This can occur at Layer 2 or Layer 3, but the sub-interface context suggests Layer 3 involvement.
The question's structure implies the layer number for the sub-interface mode, which is Layer 3 in VXLAN contexts for routing and gateway functions. Thus, the acronym (digit) to enter is 3.
NEW QUESTION # 45
Which of the following statements are true about common storage types used by enterprises?
Answer: C,D
Explanation:
Comprehensive and Detailed in Depth
A . FTP servers are typically used for file storage.
This is correct. FTP (File Transfer Protocol) servers are indeed a common way to store and share files. They are widely used for basic file storage and transfer needs.
B . Object storage devices are typically disk arrays.
This is incorrect. Object storage devices are not typically disk arrays in the traditional sense. Object storage is designed for massive amounts of unstructured data. While they use disks for persistence, they present data as objects with metadata, rather than as blocks or files. Object storage solutions often use distributed systems across many servers, not just a single array.
C . Block storage applies to databases that require high I/O.
This is correct. Block storage is ideal for applications that demand high I/O performance, such as databases. Block storage provides raw, unformatted data blocks, giving applications direct control and low latency.
D . Block storage typically applies to remote backup storage.
This is partially true, but not the typical primary use case. While block storage can be used for remote backups, it is generally considered less efficient and more expensive than object storage for this purpose. Object storage is better suited for large, unstructured backup datasets. Block storage is better for applications that need fast read/write speeds, such as databases and virtual machines.
Therefore, the correct answers are A and C.
Reference to Huawei Data Center Network documents:
Huawei storage product documentation detailing block storage (e.g., OceanStor Dorado), file storage, and object storage (e.g., OceanStor Pacific) characteristics and use cases.
Huawei white papers on data center storage architectures, which compare and contrast different storage types.
Huawei HCIP-Storage training materials, which will have very detailed information regarding each of the storage types, and their use cases.
