Pass the Cisco CCNP Data Center 300-635 Questions and answers with CertsForce

In the NXAPI-CLI JSON-RPC interface on Cisco Nexus switches, the ‘cli’ command is used to execute non-configuration CLI commands, which is equivalent to a POST operation in this context. Therefore, option A is correct. References:

Official documentation from Cisco regarding NXAPI.

The API GET request to the ACI APIC is used to read information from a managed object (B) and an object class (D), which represents specific types of managed objects within ACI’s object model. It does not create new interfaces (A) and the response format (C, E) cannot be determined from the URL alone. References: Cisco Data Center Automation

 The code snippet is intended to configure VLAN 10 in Cisco UCS. After creating the VLAN object and adding it with handle.add_mo(newvlan), it is essential to commit the changes to the UCS Manager for them to take effect. This is done by invoking handle.commit(). Without this step, the changes will not be saved, and VLAN 10 will not be configured.

The Cisco Data Center Network Manager (DCNM) REST API provides a robust platform for automating various tasks in the data center. Two of its capabilities include:

A: The DCNM REST API uses the dcnm-token header for requests authentication after initial basic authentication. This token-based authentication is more secure as it reduces the need to repeatedly send credentials over the network.

E: The DCNM REST API is organized into different management areas such as Classic LAN, LAN Fabric, Media Controller, and SAN Management. This categorization allows for targeted automation and management within specific domains of the data center network.

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 Python code in the exhibit is using the Cobra SDK to interact with Cisco’s Application Centric Infrastructure (ACI). The code performs the following actions:

It logs into the ACI fabric using credentials provided.

It creates a new Virtual Routing and Forwarding (VRF) instance named “DevNet_VRF” within a tenant named “DevNet_Tenant”.

It creates a new Bridge Domain (BD) named “DevNet_BD” within the same tenant and associates it with the previously created VRF.

It defines a subnet within this Bridge Domain with the network address “10.10.10.1/24”, which is labeled as “DevNet_Subnet”.

An Application Profile (AppProfile) named “DevNet_App” is created within the tenant.

An Endpoint Group (EPG) named “DevNet_EPG” is created and associated with both the AppProfile (“DevNet_App”) and BridgeDomain (“DevNet_BD”).

Therefore, options B and C are correct: B. This action creates an EPG called “DevNet_EPG” inside an AppProfile called “DevNet_App” located in an ACI tenant called “DevNet_Tenant”. The EPG is linked to a BridgeDomain called “DevNet_BD”. C. This action creates a subnet called “DevNet_Subnet” inside VRF “DevNet_VRF” located in an ACI tenant called “DevNet_Tenant” and sets its network address to “10.10.10.1/24”.

The -brief command in the Cisco bigmuddy-network-telemetry-collector is used to display only the message headers. This command provides a concise view of the telemetry data streamed from XR routers, which is useful for quick inspections or debugging purposes without the need for full message details1.

 The DCNM API is REST-based, allowing third parties to test and develop application software. It supports a wide range of operations that can also be performed using the DCNM GUI, which uses these REST APIs to render the GUI itself. This means that the same tasks available through the API can be accessed and managed through the graphical user interface, providing flexibility in how network administrators interact with DCNM23.

To isolate a new package from the main code base, creating a new virtual environment is the best practice. This allows for the installation and testing of the new package without affecting the existing code or dependencies. Performing a pip install of the new package within this isolated environment ensures that any potential issues or conflicts are contained. References :=
