Question 1

In an MPLS VPN network, which of the following operations can "ensure that the PE device correctly associates with the corresponding VPN instance after receiving a VPNv4 route"?

A. Configure routing policies on the PE device to import VPNv4 routes to the corresponding VPN instance. B. Configure a VPN instance on the P device to pass routing association information. C. No configuration is required; the PE device automatically associates with the VPN instance. D. Configure the BGP protocol on the CE device and specify the VPN instance.

Question 2

In MPLS VPN network troubleshooting, if "the PE device has learned the remote CE route, but the local CE device still cannot ping the remote CE", which of the following troubleshooting steps should be performed first?

A. Check if the operating system of the remote CE device is running normally. B. Check if the IP address of the VPN instance interface on the local PE device is on the same network segment as the CE device. C. Check if the MPLS LSP is established on the P device. D. Check if the BGP VPNv4 neighbor between PE devices is established normally.

Question 4

In Huawei's SD-WAN solution, for the scenario of " branch multi-link (MPLS + Internet + 5G) load balancing", which of the following technologies can "dynamically adjust the traffic allocation ratio according to the real-time bandwidth utilization of the link"?

A. All traffic is prioritized to use the MPLS link; other links are only used as cold backups. B. Allocate traffic according to a fixed ratio (e.g., 40% MPLS, 30% Internet, 30% 5G), without adjusting for bandwidth changes. C. Randomly allocate traffic to each link, without considering bandwidth utilization. D. Dynamic load balancing based on link bandwidth utilization (reducing traffic on links with high utilization and increasing traffic on links with low utilization).

Question 5

For the "branch multi-link access" scenario, which of the following functions of Huawei's SD-WAN solution can achieve load balancing and redundancy backup of the links? (Multiple choice)

A. Rapid link failure switching (detecting failures in milliseconds and switching to backup links) B. No link health check; manual link switching is required after a failure . C. Traffic sharing based on bandwidth ratio (e.g., Internet links handle 70% of the traffic, MPLS links handle 30%). D. All traffic flows through a single link, with other links left idle as cold backups. E. Link health checks (such as ICMP ping, TCP probes to monitor link status in real time)

Question 6

In Huawei's SD-WAN solution, which of the following technologies can "achieve full interconnection communication between multiple branches without manually creating tunnels between each pair of branches"?

A. Direct communication between branches is prohibited; access to headquarters is permitted only. B. All inter-branch communication is relayed through headquarters, increasing latency. C. Manually creating point-to-point tunnels for each pair of branches is complex to configure. D. SD-WAN Fully Interconnected Automatic Tunneling Technology (Dynamically Discover Branches and Establish Tunnels)

Question 10

When OSPF is deployed on a wide area network (such as an inter-carrier link), which of the following configurations can improve the adaptability and stability of the OSPF network? (Multiple choice)

A. Adjust OSPF hello/dead times (e.g., change the hello time to 30 seconds to adapt to high latency in wide area networks). B. Divide OSPF into reasonable areas (e.g., divide cross-regional links into backbone areas Area 0). C. Without configuring OSPF authentication, any device can access the OSPF domain . D. Using the default hello/dead times (10s/40s) is not suitable for wide area network latency. E. Enable OSPF authentication (such as zone authentication to prevent fake LSA injection).
