  Answers to Practice Test Questions

 4.  B.  The term DevOps is used to describe the framework responsible for assisting in 

network automation. It is usually written in conjunction with network operations, but it is 

considered a development function using the DevOps framework. The term NetOps refers 

to the network operation team’s responsibility. The term SysOps is used to describe the 

control of network systems such as DNS, Active Directory (AD), and DHCP, just to name 

a few. The term SecOps refers to the security operation as it pertains to the network.

 5.  A.  The management methodology that is commonly used by developers for network 

automation is Lean and Agile. Agile focuses on an adaptive approach for simultaneous 

workflows, such as the configuration of a default route on several routers. The Waterfall 

management methodology is used for projects in a linear process that does not allow for 

going back to a prior phase. The Kanban management methodology is used to improve 

existing processes. Scrum is primarily focused on getting more work done more quickly.

 6.  D.  After a network automation script is released to production, the very next process 

should be to monitor its effects on the network. This step should already be considered 

with pre-built metrics so that you can positively conclude its intended function. The 

testing step should have been done prior to the deployment phase. The building phase is 

done when you are ready to test a completed configuration change. The planning phase 

is the first phase before anything is put into motion; it is where you have determined the 

metrics for the project, which determines if the changes are successful.

 7.  B.  The YAML Ain’t Markup Language (YAML) markup language uses mapping to define 

keys and values as pairs. Definition is not a term used with YAML; therefore, option A 

is an invalid answer. Lists are keys with multiple values in the form of a list. Keys are 

categories that contain a value in the key-value pair.

 8.  A.  A YAML file will always begin with three dashes. This is how you know you are 

working with a YAML file structure. Files that start with a hashbang preprocessor are 

normally scripts, and the hashbang describes to the operating system which command 

interpreter to use. A file that has its content contained between curly braces or square 

braces is normally a JSON file.

 9.  D.  Extensible Markup Language (XML) was adopted from HyperText Markup Language 

(HTML) as a storage method for systems to interchange data. YAML Ain’t Markup 

Language (YAML) is a white space structured file that is also used to store data for the 

interchange of information. JavaScript Object Notation (JSON) is another structured 

storage method for data and was originally created for use with JavaScript and gained 

popularity with other languages. Comma-separated values (CSV) is a flat data storage 

method that is popular when lists of information must be passed from system to system.

 10.  A.  YAML Ain’t Markup Language (YAML) is a white space structured file that is also 

used to store data for the interchange of information. JavaScript Object Notation (JSON) 

is structured with curly and square brackets. Extensible Markup Language (XML) was 

adopted from HyperText Markup Language (HTML), which uses opening and closing 

tags. Comma-separated values (CSV) is a flat data storage method that uses commas to 

delimit the fields of information held on each line.
