Question 3

On a campus network, which of the following problems may occur when you manually create a static VXLAN tunnel?

A. Remote MAC addresses can be learned by the VTEP only through data flooding.

B. Although the static VXLAN tunnel mode supports the distributed gateway scenario, the configuration involves a heavy workload and is complex to adjust.

C. A static VXLAN tunnel also uses corresponding protocols on the control plane, which consumes device resources.

D. If N devices need to establish static VXLAN tunnels, a maximum of N(N -1)/2 tunnels need to be manually configured, which involves a heavy workload.

Question 8

In a scenario where SR Policies are dynamically established through the controller, which of the following statements about the SR Policy solution architecture is incorrect?

A. The controller uses NETCONF to deliver configurations such as service interfaces and routing policies.

B. The controller uses telemetry to deliver information such as SRv6 SIDs to construct SID entries.

C. The controller uses BGP-LS to collect tunnel topology information and computes SR Policy paths.

D. The controller uses BGP IPv6 SR Policy to deliver SR Policy information, such as the color, headend, and endpoint information.

Question 9

In an MPLS VPN network, two-layer MPLS labels are added into data packets before they are transmitted over the public network. Which of the following statements regarding data packet processing are correct?

A. The penultimate-hop device receives a packet with an outer label.

B. The egress PE sends the data packet to the correct VPN based on the inner label.

C. The IP data packet received by egress LSR is without labels.

D. The penultimate hop removes the outer label before forwarding the data packet to a peer egress PE.

Question 10

Which of the following statements about OPS (Open Programmability System) application scenarios is incorrect?

A. The OPS can be used to automatically check the health status of devices.

B. The OPS can reduce the impact of the network environment in some cases. For example, when collected information is transmitted to a server, the Python script can be used to temporarily store the execution result to the device when the network is disconnected. After the network is reconnected, the execution result is transmitted to the server.

C. When the OPS is used to automatically deploy unconfigured devices, a Python script is used to obtain the IP addresses of the software and configuration file server and download the system software and configuration file.

D. To enable a network device to automatically send a configuration file to the server after the device configuration is saved, users can use the maintenance assistant to create a timer trigger condition and periodically run the Python script.
