H12-893_V1.0 Exam Dumps : HCIP-Data Center Network V1.0

Zero Touch Provisioning (ZTP) in Huawei’s CloudFabric automates device setup using DHCP. Let’s evaluate each option:

A. Default gateway address:This is true. DHCP can deliver the default gateway address to configure routing for the device.TRUE.

B. SFTP server address:This is false. SFTP server addresses are not standard DHCP options; they may be configured manually or via other protocols (e.g., TFTP for boot files).FALSE.

C. DNS server address:This is true. DHCP can provide DNS server addresses (Option 6) for name resolution during ZTP.TRUE.

D. Temporary management IP address:This is true. DHCP assigns temporary IPs (e.g., Option 50) for management during initial provisioning in ZTP.TRUE.

Thus,A, C, and Dcan be delivered by a DHCP server in ZTP.References:Huawei CloudFabric Data Center Network Solution – ZTP Configuration; HCIP-Data Center Network Training – ZTP Process.

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 Dare true statements about IP address planning.References:Huawei CloudFabric Data Center Network Solution – IP Planning; HCIP-Data Center Network Training – Address Management.

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 isLayer 3in VXLAN contexts for routing and gateway functions. Thus, the acronym (digit) to enter is3.References:Huawei CloudFabric Data Center Network Solution – VXLAN Configuration Guide; HCIP-Data Center Network Training – VXLAN Access Methods.
