How does requesting a synchronous API operation differ from requesting an asynchronous API operation?
Answer: D
D https://www.techtarget.com/whatis/definition/synchronous-asynchronous-API What is the difference between synchronous and asynchronous APIs? Synchronous and asynchronous APIs differ in the following ways: Synchronous APIs: With synchronous APIs, the expectation is that data will be returned immediately. An API is usually synchronous when data or service availability, resources and connectivity are high and low latency is a requirement. Asynchronous APIs: Asynchronous APIs are also known as async APIs. With an asynchronous process, the availability of a resource, service or data store may not be immediate. The API may have to wait for a backend response. These APIs may provide a callback notification to the requester when the requested resource is ready. Asynchronous requests are useful in maintaining an application's functionality rather than tying up its resources waiting on a request. An API may be asynchronous where data or service availability and connectivity is low or oversaturated with demand.

Which method should be used to safely store the API keys?
Answer: A
It's A Definitely please see https://developer.cisco.com/codeexchange/github/repo/cldeluna/creds_in_env/ "Environment Variables Set credentials and keys as environment variables that your script can access during runtime. In fact these can be set interactively (think CLI) and via a file as well (look for .env or .ini files in repositories and you now know what they are) For me, environment variables made the most sense"

Refer to the exhibit.
An administrator attempts to perform a GET using the Cisco IOS XE RESTCONF API to return the hostname of a device. The sequence diagram illustrates the HTTP messages observed. Which change to the API request resolves the issue?
Answer: B
with no special chars: A. Remove the -H ‘Accept: application/yang-data+json’ HTTP header because it is not required. B. Use -u cisco:cisco instead of -u ‘cisco:cisco’ C. Change the request method from -X “GET” to -X “POST” D. Add Content-Type HTTP header with ‘application/yang-data+json’ using -H ‘Content-Type: application/yang-data+json’

Which two statements describe the advantages of using a version control system? (Choose two.)
Answer: AC
A and C are correct. [..] If you have a team of developers working on a project, all writing new code or changing previously written code, losing those files could set you back weeks or months. Version control can protect your code by allowing changes to be checked in (through a process known as a code commit) to a hierarchical tree structure of folders with files in them. You often don’t know what a developer might need to change or has changed, but the version control system does. Each check-in is tagged with who made the change and what the person changed within the code. Instead of using inefficient techniques such as file locking, a version control system handles concurrent check-ins, allowing two programmers to commit code at the same time. [..] Another aspect of a version control system is the ability to branch and merge code built independently. This is very useful if you are writing code on a part of an application that could conflict with another part written by another team. Page 170 CCNA DevNet (DEVASC) - 200-901
