A financial services company is deploying a new data center fabric using Huawei CloudEngine switches. They require strict traffic segmentation between their trading, analytics, and corporate departments. The solution must support VM mobility and scale to thousands of tenants. The lead architect has chosen a VXLAN EVPN solution. Which EVPN route type is responsible for advertising the MAC and IP address bindings of hosts within the fabric?
A network automation engineer is tasked with creating a Python script to retrieve the operational state of all BGP peers on a Huawei NetEngine router. To ensure the script is robust and uses a structured data format, the engineer decides to use NETCONF and YANG. Which of the following Python code snippets correctly utilizes the `ncclient` library to perform a ` ` operation for BGP peer information?
A large enterprise has a multi-area OSPF network. To improve stability and reduce the size of the routing table in Area 1, a network administrator wants to prevent specific Type 5 LSAs originating from an ASBR in Area 2 from being propagated into Area 1. The ABR connecting Area 0 and Area 1 is R5. What is the most effective method to achieve this on R5?
In a Huawei CloudCampus solution, a network administrator needs to provide differentiated network access for employees, guests, and IoT devices on the same physical infrastructure. Employees require 802.1X authentication for secure access to corporate resources. Guests need a simple web-based login with time-limited access. IoT devices, which lack 802.1X supplicants, must be authenticated based on their hardware address. Which combination of authentication methods should be configured to meet all these requirements? (Select THREE)
A service provider is implementing Segment Routing over an MPLS data plane (SR-MPLS). An engineer is analyzing the label stack on a packet traversing the network. What does the Segment Routing Global Block (SRGB) represent in this context?
True or False: In a Huawei SD-WAN solution, the iMaster NCE-WAN controller uses BGP to distribute routing information and topology to the CPEs in the overlay network.
A DevOps team is adopting Infrastructure as Code (IaC) to manage their network of Huawei devices. They are using Ansible for configuration management. To ensure their playbooks are reliable and can be run multiple times without causing unintended changes, which core principle of Ansible must their tasks adhere to?
During the troubleshooting of an MPLS L3VPN, a network engineer discovers that customer routes learned by PE1 from CE1 are not being received by PE2. The engineer has verified that the IGP is stable, LDP sessions are established, and the MP-BGP session between PE1 and PE2 is up. What is the most likely cause of this issue? ```mermaid graph LR CE1---PE1 PE1---P1 P1---P2 P2---PE2 PE2---CE2 subgraph MPLS Core P1 P2 end subgraph Customer A CE1 CE2 end ```
A consultant is designing a large-scale BGP network and needs to reduce the number of iBGP sessions required. The network consists of 50 routers in a single Autonomous System (AS). Instead of a full mesh, the consultant proposes using two Route Reflectors (RRs) for redundancy. Which BGP attribute is used by the RRs to prevent routing loops when advertising routes learned from one client to another client?
A telecommunications company is upgrading its core network to support network slicing for 5G services. They are using Huawei NetEngine routers and the CloudWAN solution. To provide guaranteed bandwidth and low latency for a critical mobile broadband (eMBB) slice, which technology is most suitable for creating hard, isolated network pipes?
