1 Which two concepts describe test-driven development? (Choose two.)

• User acceptance testers develop the test requirements.

• It enables code refactoring.

• Tests are created when code is ready for release

• Implementation is driven by incremental testing of release candidates

• Write a test before writing code

A developer is attempting to retrieve all the messages from a Cisco Webex space. The server responds by sending the first 1,000 messages. The developer must make additional requests to retrieve the rest of the messages. Which API constraint is described in this scenario?

• payload limiting

• throttling

• pagination

• rate limiting

Refer to the exhibit. A collaboration engineer has developed a script to automate the gathering of information by providing the email address of the individual.When the engineer tests the script, a 401 error is received. Which command fixes the script?

• Add ג€Authorizationג€: ג€Bearer <WEBEX_TOKEN>ג€ to the headers.

• Add ג€Authenticationג€: ג€Basic <WEBEX_TOKEN>ג€ in the base_url after ג€https://ג€.

• Add ג€<Authorization>:<password>@ג€ in the base_url after ג€https://ג€.

Refer to the exhibit. An engineer writes a Python script that uses two different API calls to query Cisco DNA Center for the number of interfaces on a device. The engineer notices that the two API calls produce different results. Why are fewer interfaces returned for the same device when the 'get_all_interfaces' API call is used?

• times out

• rate limit

• pagination

• invalid password

A developer creates a web application that receives a username and password and uses them to sync the credentials to other services through HTTPS. API keys to services are part of the configuration files of the application, but the credentials to the database that stores the synchronization logs are obtained through an external vault service. What is the security issue in this scenario?

• Communication between the application and the services is not encrypted.

• The database credentials should be stored in the configuration files so that they are secured on the same server.

• The API keys are stored in the configuration files but should be stored in the vault service

• The synchronization logs should be encrypted and not stored in a relational database

Which HTTP code group is issued when a request is received successfully, understood, and processed?

• 2xx

• 3xx

• 4xx

• 5xx
