Question 2

Which two actions do Python virtual environments allow users to perform? (Choose two.)

A: Simplify the CI/CD pipeline when checking a project into a version control system, such as Git.
B: Efficiently port code between different languages, such as JavaScript and Python.
C: Run and simulate other operating systems within a development environment.
D: Quickly create any Python environment for testing and debugging purposes.
E: Quickly create an isolated Python environment with module dependencies.

Correct Answer: DE

Question 3

What are two benefits of leveraging Ansible for automation of Cisco IOS XE Software? (Choose two.)

A: Ansible playbooks are packaged and installed on IOS XE devices for automatic execution when an IOS device reboots.
B: All IOS XE operating systems include Ansible playbooks for basic system administration tasks.
C: It is a device-independent method for automation and can be used with any type of device or operating system.
D: Ansible playbooks can be written from the IOS XE EXEC command line to configure the device itself.
E: It does not require any modules of software except SSH to be loaded on the network device.

Correct Answer: AC

Question 4

Refer to the exhibit. The task is to create a Python script to display an alert message when a Meraki MX Security Appliance goes down. The exhibit shows sample data that is received. Which Python snippet displays the device name and the time at which the switch went down?

Correct Answer: B

Question 5

Refer to the exhibit. The goal is to write a Python script to automatically send a message to an external messaging application when a rogue AP is detected on the network. The message should include the broadcast SSID that is in the alert.
A function called “send_to_application” is created, and this is the declaration:
send_to_application(message)
The exhibit also shows the data that is received by the application and stored in the variable return_val. Which Python code completes the task?

Correct Answer: A

For number in range value is required for the application to send the alert. Bssids are also included.

Question 6

Which two features are foundations of a software-defined network instead of a traditional network? (Choose two.)

A: control plane and data plane are tightly coupled
B: build upon a robust software stack
C: requires device by device-level configurations
D: automated through expressed intent to a software controller
E: requires significant physical hardware resources

Correct Answer: BD

In traditional networks, control plane and data plane are coupled tightly. It also requires device by device configurations and of course, it uses physical hardware resources to function. Whereas, SDN is based on a software stack. In Cisco SDNs are automated through expressed intent to a software controller.

Question 7

A new project called “device_status” must be stored in a central Git repository called “device_status” with the first file named “device_status.py”. The Git repository is created using the account python_programmer. Which set of commands inserts the project into Git?

Correct Answer: A

Question 8

What are two characteristics of synchronous calls to APIs? (Choose two.)

A: They can be used only with certain programming languages.
B: They make your application less portable, so asynchronous calls are preferred.
C: They can add perceived latency to your application if data is not received.
D: They block until a response is returned from the servers.
E: They do not block while waiting for the API to be processed.
