The Huawei H12-893_V1.0 certification examination is an essential component of professional development, and passing this Huawei H12-893_V1.0 test can increase career options and a rise in salary. Nonetheless, getting ready for the HCIP-Data Center Network V1.0 (H12-893_V1.0) exam may be difficult, and many working professionals have trouble locating the Huawei H12-893_V1.0 practice questions they need to succeed in this endeavor.
NEW QUESTION # 14
VXLAN is a network virtualization technology that uses MAC-in-UDP encapsulation. What is the destination port number used during UDP encapsulation?
Answer: C
NEW QUESTION # 15
Which of the following technologies are Layer 4 load balancing technologies? (Select All that Apply)
Answer: A,B,C
Explanation:
Layer 4 load balancing operates at the transport layer (OSI Layer 4), using TCP/UDP protocols to distribute traffic based on information like IP addresses and port numbers, without inspecting the application-layer content (Layer 7). Let's evaluate each option:
A . Nginx: Nginx is a versatile web server and reverse proxy that supports both Layer 4 and Layer 7 load balancing. In its Layer 4 mode (e.g., with the stream module), it balances TCP/UDP traffic, making it a Layer 4 load balancing technology. This is widely used in Huawei's CloudFabric DCN solutions for traffic distribution. TRUE.
B . PPP (Point-to-Point Protocol): PPP is a Layer 2 protocol used for establishing direct connections between two nodes, typically in WAN scenarios (e.g., dial-up or VPNs). It does not perform load balancing at Layer 4 or any layer, as it's a point-to-point encapsulation protocol. FALSE.
C . LVS (Linux Virtual Server): LVS is a high-performance, open-source load balancing solution integrated into the Linux kernel. It operates at Layer 4, using techniques like NAT, IP tunneling, or direct routing to distribute TCP/UDP traffic across backend servers. It's a core Layer 4 technology in enterprise DCNs. TRUE.
D . HAProxy: HAProxy is a high-availability load balancer that supports both Layer 4 (TCP mode) and Layer 7 (HTTP mode). In TCP mode, it balances traffic based on Layer 4 attributes, making it a Layer 4 load balancing technology. It's commonly deployed in Huawei DCN environments. TRUE.
Thus, A (Nginx), C (LVS), and D (HAProxy) are Layer 4 load balancing technologies. PPP is not.
NEW QUESTION # 16
The underlay routing protocol has already converged, but one VTEP cannot establish EVPN sessions with another. Which prerequisite should be verified first?
Answer: D
Explanation:
Even with complete IP connectivity, EVPN requires operational MP-BGP neighbor relationships.
Without successful BGP session establishment, overlay routes cannot be exchanged, preventing endpoint discovery and VXLAN communication.
NEW QUESTION # 17
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 # 18
In Huawei CloudFabric Solution, OSPF or BGP can be used on the underlay network of a DC.
Answer: B
Explanation:
In Huawei's CloudFabric Solution, the underlay network provides the physical infrastructure for VXLAN overlays. Both OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol) are supported routing protocols:
OSPF: Suitable for smaller to medium-sized DCNs, offering fast convergence and simplicity.
BGP: Preferred for large-scale DCNs, providing scalability and multi-tenancy support (e.g., EBGP for inter-AS or iBGP for intra-DC).
Huawei documentation confirms flexibility in choosing OSPF or BGP based on network size and requirements. The statement is TRUE (A).
