Cisco 300-635 - Automating Cisco Data Center Solutions (DCAUTO)

The Python code Vrf(fvTenant(uniMo, 'CustA'), 'CustA_VRF) creates a VRF in an ACI tenant using the Cobra SDK. The Vrf class is instantiated with a parent fvTenant object and the name of the VRF.

The EEM script in the exhibit is designed to monitor for specific syslog messages. If any of the patterns specified (“copy bootflash:* running-config”, “copy run start”, or “Hello”) occur within a 120-second window, the script will trigger the reload of module 1 on the Cisco Nexus 9000 switch. This action is based on the occurrence of any one of the patterns, not all, which aligns with option B. References:

Simple Network Management Protocol (SNMP) traditionally operates on a pull model where the management system periodically polls or requests information from network devices at set intervals. In contrast, model-driven telemetry is designed to use a push model where information is sent by network devices to the management system proactively when certain conditions are met or at set intervals without waiting for an explicit request from the management system. References := Cisco IOS XE Model-Driven Telemetry

 The ucs_vlans module is part of the Ansible collection for Cisco UCS (Unified Computing System) and is used to manage VLANs on Cisco UCS Manager. When working with Cisco UCS, VLANs are a crucial aspect of network segmentation and management. The ucs_vlans module allows users to configure VLAN settings such as the VLAN ID, name, and state. It also supports advanced features like fabric configuration and multicast policies.

Cisco Intersight REST API requires a secure authentication process that involves creating a SHA256 hash of the message body and headers. This ensures that the message integrity is maintained and verifies that the message has not been tampered with during transit. Even if the message body is empty, a SHA256 hash is still required. Additionally, the use of RSA private keys enhances security, but the specific key size requirement was not mentioned in the provided resources6

The command telemetry_receiver.py --ip-address -port  is used to start a Python network telemetry collector. This command specifies the IP address and port where the telemetry receiver will listen for incoming telemetry data from network devices

The Cobra SDK is used for automating tasks within Cisco’s Application Policy Infrastructure Controller (APIC). To create a new tenant named ‘Cisco’, the correct code is Tenant = Tenant(topMo, name='Cisco'). This line of code initializes a new instance of the Tenant class, with topMo as the parent managed object and ‘Cisco’ as the name of the tenant. This effectively instructs the APIC to create a new tenant with the given name.
