Cisco 350-501 Exam With Confidence Using Practice Dumps

The configuration in Option A is correct for enabling dial-out telemetry streams using gRPC on devices with TLS disabled.

It uses model-driven telemetry (MDT), which is a new method of monitoring network devices. Unlike traditional methods that pull data from the device, MDT pushes data from the device to the collector.

In this configuration:

Telemetry is model-driven.

It specifies a destination group with an IP address and port number where the telemetry data will be sent.

The encoding is self-describing-gpb (Google Protocol Buffers).

The protocol used is TCP.

This setup ensures that telemetry data is sent to the specified collector without requiring TLS encryption.

 Enabling MPLS LDP IGP Synchronization ensures that the IGP advertises a route only if there is a corresponding label binding from LDP. This synchronization helps prevent blackholing traffic when there is a direct link failure in the network. When the B-C link failed, the IGP could find an alternate path via routers E and F, but without LDP synchronization, the labels for MPLS were not available on this new path, leading to traffic loss. By enabling LDP IGP Synchronization, routers will only use paths for which a complete set of labels exists, ensuring label forwarding occurs on the alternate path.

This configuration sets up policing rules for different protocols including CDP (Cisco Discovery Protocol) and ARP (Address Resolution Protocol), with specific rate limits for invalid packets as well as CDP and ARP protocols. References: Implementing and Operating Cisco Service Provider Network Core Technologies source documents or study guide
