Which command reverses the last commit without changing the index file or the working tree position?
Answer: C
C is correct: "git reset [ ] [ ] This form resets the current branch head to and possibly updates the index (resetting it to the tree of ) and the working tree depending on . If is omitted, defaults to --mixed. The must be one of the following: --soft Does not touch the index file or the working tree at all (but resets the head to , just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it." https://git-scm.com/docs/git-reset

A file in a local Git repository has been updated and issued the git add . command. The git diff command has been run to compare the changes to the previous commit, but nothing shows. Which action identifies the problem?
Answer: D
I would say D is correct. From both of these resourses I can conclude that: "git diff [ ] [--] [ …] This form is to view the changes you made relative to the index (staging area for the next commit). In other words, the differences are what you could tell Git to further add to the index but you still haven’t. You can stage these changes by using git-add[1]." "git diff [ ] --cached [--merge-base] [ ] [--] [ …] This form is to view the changes you staged for the next commit relative to the named . Typically you would want comparison with the latest commit, so if you do not give , it defaults to HEAD. If HEAD does not exist (e.g. unborn branches) and is not given, it shows all staged changes. --staged is a synonym of --cached." https://git-scm.com/docs/git-diff

Which protocol runs over TCP port 830?
Answer: A
DRAG DROP - Drag and drop the code from the bottom onto the box where the code is missing to authenticate with the Cisco DNA Center REST API by using basic authentication. Then generate a token for later use. Not all options are used.

Which solution reduces costs from MPLS, improves application performance, and simplifies operations?
Answer: B
A developer has experienced security issues with a previously developed application. The API offered by that application is open and without any constraints. During a recent attack, the application was overloaded with API requests. To address this issue, an API constraint is implemented to protect the application from future attacks or any sudden throttling. Which API constraint must the application developer implement in this situation?
Answer: B
What is the difference between YAML and JSON data structure?
Answer: B
B. YAML uses indentation; JSON uses brackets and braces YAML (YAML Ain't Markup Language) and JSON (JavaScript Object Notation) are both data serialization formats, which are used to store and transmit data. They both have similar functionality and are used for similar purposes, but there are some key differences between the two. One of the main differences between YAML and JSON is in their data structure. YAML uses indentation to indicate the structure of the data, while JSON uses brackets and braces. In YAML, indentation is used to indicate the level of nesting of elements and to indicate the beginning and end of an object or an array. In JSON, brackets are used to define the beginning and end of an array, and braces are used to define the beginning and end of an object.
