 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.

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:

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 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.

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

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 correct iteration for creating three EPGs in Cisco ACI using an Ansible task is found in option C. This task utilizes the aci_epg module, which is part of Ansible’s suite of modules for managing Cisco ACI environments. The task includes a loop that iterates over a list of EPG names, creating each one in turn. This approach is efficient for automating the creation of multiple EPGs, reducing the need for repetitive task definitions. References := For more information on automating Cisco Data Center solutions, including the use of Ansible for task automation, you can refer to the official Cisco documentation and training resources such as the Implementing Automation for Cisco Data Center Solutions (DCAUI) course.

 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.

The output shown in the exhibit is a list of distinguished names (DNs) for Cisco Unified Computing System (UCS) blades within specific chassis. The correct PowerTool commands to provide this output would be those that retrieve information about UCS blade servers and then select their distinguished names. The command Get-UcsBlade | Select-Object Dn retrieves all the UCS blade servers and then pipes them to the Select-Object cmdlet to display only their distinguished names, which matches the pattern seen in the exhibit. Similarly, Get-UcsRackUnit | Select-Object Dn could potentially provide a similar output if rack units are named in a similar fashion to blades within the system’s naming conventions. References :=

The top level in the ACI Management Information Tree is polUni. This is the top-level class for all policy definition and resolution objects within the Cisco ACI Policy Model. It serves as the root for policy namespace in the Management Information Tree12.

In Cisco’s ACI, the Management Information Tree (MIT) uses several attributes to uniquely identify managed objects. ‘RN’ stands for Relative Name, which is the name of an object within its parent’s context. ‘DN’ stands for Distinguished Name, which is a unique name that includes the full path in the MIT hierarchy.

Which code must be inserted into the red box to create this tenant? A. Tenant = NewTenant(name=‘Cisco’) B. tenant — Tenant(topMo, name-Cisco’) C. Tenant = Tenant(topMo, name=‘Cisco’) D. Tenant = Tenant(‘Cisco’)

Synchronous API calls are blocking, meaning they hold up code execution until a response is returned from the server. This can lead to perceived latency or performance lag in an application if not managed properly. In contrast, asynchronous API calls do not block code execution; they allow the program to continue running and handle the response once it’s available, typically through a callback function

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.

To access the REST API browser within Cisco UCS Director, one must enable the Developer menu from the Cisco UCS Director interface. After enabling this option, select ‘Orchestration’ and then choose ‘REST API Browser’. This allows users to interact with the various APIs provided by Cisco UCS Director for automation and orchestration purposes. References: Cisco UCS Director REST API Guide

The API Inspector in Cisco’s APIC is used to capture and display API requests made by the APIC GUI. It helps users learn or identify the sequence of API calls for specific operations performed in the APIC GUI. This tool is useful for developers who want to automate tasks using RESTful APIs by providing them with exact API calls that can be replicated in scripts or applications. References :=
