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?
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Answer:
C
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?
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Answer:
D
Explanation:
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
Answer:
BD
Explanation:
:
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?
- A. Option A
- B. Option B
- C. Option C
- D. Option D

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.

Question 12
Refer to the exhibit.
How many YANG models does the NETCONF <get> operation interact with?
- A. one
- B. two
- C. three
- D. four
Answer:
B
Explanation:
:
The get operation tag is at the beginning of the document. It interacted only with NTP and its related
services. There get operation interacted only with one model.
Question 13
Which statement describe the difference between OpenConfig and native YANG data models?
- A. Native models are designed to be independent of the underlying platform and are developed by vendors and standards bodies, such as the IETF.
- B. Native models are developed by individual developers and designed to apply configurations on platforms.
- C. OpenConfig models are developed by vendors and designed to integrate to features or configurations that are relevant only to that platform.
- D. Native models are developed by vendors and designed to integrate to features or configurations that are relevant only to that platform.
