Questions # 1:

Which two components are required from the Cisco Intersight REST API Authentication? (Choose two.)

Options:

SHA256 hash of the message body and message headers

SHA256 hash of the message body, including empty message bodies

RSA private key with a key size of 2048

RSA private key with a key size of 1024

SHA384 hash of the message body, excluding empty message bodies

Answer

A, B

Explanation

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

Questions # 2:

Which two application isolation options are available when Kubernetes is deployed with the ACI CNI plug-in? (Choose two.)

Options:

Process Isolation

Namespace Isolation

Cluster Isolation

Server Isolation

VM Isolation

Answer

B, C

Explanation

Kubernetes deployed with the ACI CNI plug-in offers Namespace Isolation and Cluster Isolation. Namespace Isolation segregates resources within the same cluster using Kubernetes namespaces, while Cluster Isolation ensures complete separation between different clusters. References:

Questions # 3:

A set of automation scripts work with no issue from a local machine, but an experiment needs to take place with a new package found online.

How is this new package isolated from the main code base?

Options:

Add the new package to your requirements txt file.

Create a new virtual machine and perform a pip install of the new package

Perform a pip install of the new package when logged into your local machine as root

Create a new virtual environment and perform a pip install of the new package

Answer

Explanation

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 :=

Questions # 5:

Which two initial actions should be taken when exploring automation capabilities for ACI? (Choose Two)

Options:

Write scripts that leverage the Python Standard Library

Look for an open-source package or SDK

Use the API Inspector and test API Calls

Develop an open-source package or SDK

Use the ncclient command to explore the NETCONF capabilities

Answer

B, C

Explanation

When exploring automation capabilities for ACI, it’s beneficial to:

B. Look for an open-source package or SDK: These resources can simplify the process by providing pre-built functions and methods for common tasks.

C. Use the API Inspector and test API Calls: The API Inspector within ACI allows you to see the API calls that are made when you perform actions in the GUI, which is invaluable for understanding how to automate those actions.

Questions # 8:

What is a description of a Cisco UCS Director script module?

Options:

function to convert internal workflow tasks into Python scripts

place to store custom workflow scripts, jars, and custom lists of values for use in custom workflow

place to store external scripts that are not related to Cisco UCS Director

place to store imported scripts. Bash, and custom Python code for use in custom workflow tasks

Answer

Explanation

The Cisco UCS Director script module serves as a centralized repository within the UCS Director platform. It allows users to store custom scripts, Java archives (jars), and customized lists of values, which are crucial for creating or modifying workflows to automate tasks in a data center environment. By utilizing the script module, administrators can enhance workflow functionality with their own scripts or existing ones, thereby streamlining operations.

Question # 10

Which action fixes the code to access a child managed object?

Options:

Delete line 2.

Change dnQuery to classQuery in line 1.

Move line 2 to the last line.

Change parent to children in line 2.

Answer

Explanation

The code snippet is intended to access a child managed object within Cisco’s ACI. The current placement of line 2 (dnQuery.subtree = 'parent') specifies that the query should look at the parent objects, not the children. To fix the code so that it accesses a child managed object, line 2 should be moved to after line 3, where tenantMo is defined. This change will ensure that the subtree of tenantMo is set to ‘parent’, which means that when defaultBDmo is called in line 4, it will correctly reference a child managed object under tenantMo.
