Cisco 200-901 Online Questions & Answers

• Question 291:

  Refer to the exhibit.

  

  An engineer must authorize a REST API call. The API password is "Cisco123!". Which Bash command must be placed in the code to authorize the call?

  A. mkdir API_PASSWORD=Cisco123!
  B. set API_PASSWORD=Cisco123!
  C. cp API_PASSWORD=Cisco123!
  D. export API_PASSWORD=Cisco123!
  D. export API_PASSWORD=Cisco123!

  ---

  Explanation Explanation/Reference:In the provided Python code, the API_PASSWORD is retrieved from the environment variable API_PASSWORD. To set this environment variable in a Bash shell, the correct command to use is export. This command sets the environment variable for the current shell session and any child processes. Bash Command: export API_PASSWORD=Cisco123! This command ensures that the environment variable API_PASSWORD is set to "Cisco123!" and can be accessed by the Python script.

• Question 292:

  Which response code family is returned when further action must be taken to complete the request?

  A. 2xx
  B. 3xx
  C. 4xx
  D. 5xx
  B. 3xx

• Question 293:

  DRAG DROP Refer to the exhibit.

  

  Drag and drop the variables from the left onto the item numbers on the right that match the missing assignments in the exhibit.

  Select and Place:

• Question 294:

  DRAG DROP

  Drag and drop characteristics from the left onto the infrastructure management methodologies on the right.

  Select and Place:

  Explanation/Reference:

• Question 295:

  Which service must be configured to provide time synchronization to the devices on a network to make it easier to correlate log events?

  A. DHCP
  B. SNMP
  C. NAT
  D. NTP
  D. NTP

  ---

  NTP is specifically designed for synchronizing the clocks of devices across networks. This ensures that log events across different devices have consistent timestamps, making it significantly easier to correlate and analyze them for security purposes, auditing, troubleshooting, and performance monitoring.

• Question 296:

  DRAG DROP

  Refer to the exhibit.

  

  Drag and drop the code from the bottom onto the box where the code is missing in the Python unittest to verify whether the function returns the correct values. Not all options are used.

  Select and Place:

• Question 297:

  What is a benefit of a CI/CD pipeline for infrastructure?

  A. removes manual errors
  B. enables manual steps
  C. removes the need for operations
  D. provides variety for deployments
  A. removes manual errors

• Question 298:

  What are two benefits of implementing common data structures when working with APIs in remote systems? (Choose two.)

  A. ensures that developers are limited to using one data schema type
  B. prevents multivendor interoperability
  C. improves security in RESTful web services
  D. enforces standardized data structures
  E. leverages code that is easily managed and reused
  D. enforces standardized data structures
  E. leverages code that is easily managed and reused

  ---

  Implementing common data structures when working with APIs in remote systems has several benefits. One benefit is that it enforces standardized data structures, which helps to ensure that data is consistently organized and easy to parse. This can make it easier for developers to work with the API and understand the data being returned. Another benefit of using common data structures is that it leverages code that is easily managed and reused. This can save time and resources, as developers do not have to spend as much time writing and debugging code. It can also improve the overall quality and reliability of the API, as the code is more likely to have been thoroughly tested and debugged.

• Question 299:

  Refer to the exhibit. A network engineer wants use API update information about device interfaces. The network devices are deployed in a Cisco DevNet Sandbox and have running interfaces. Which value is suitable as the headers variable?

  

  A. {'Content-Type': 'application/yang.data+yaml', 'Accept': 'application/yang.data+yaml'}
  B. {'Content-Type': 'application/yang.data+json', 'Accept': 'application/yang.data+json'}
  C. {'Content-Type': 'application/yang.data+utf8l', 'Accept': 'application/yang.data+utf8'}
  D. {'Content-Type': 'application/restconf.data+txt', 'Accept': 'application/restconf.data+txt'}
  B. {'Content-Type': 'application/yang.data+json', 'Accept': 'application/yang.data+json'}

• Question 300:

  What is a principle of a code review process?

  A. Changes are made after the code is submitted to source control.
  B. It must not prevent code from getting into production as quickly as possible.
  C. Naming standards must be consistent.
  D. A technical lead must sign off on the review.
  C. Naming standards must be consistent.

  ---

  One of the key principles of a code review process is to ensure that naming standards are consistent. This helps maintain code readability, understandability, and maintainability. Consistent naming conventions reduce the cognitive load for developers when reading and understanding the code, making it easier to manage and less prone to errors.
