Which two HTTP code series relate to errors? (Choose two.
Correct : A, C
HTTP status codes are divided into five classes:
1xx (Informational): Request received, continuing process
2xx (Success): The action was successfully received, understood, and accepted
3xx (Redirection): Further action must be taken to complete the request
4xx (Client Error): The request contains bad syntax or cannot be fulfilled
5xx (Server Error): The server failed to fulfill an apparently valid request
Thus, the series that relate to errors are:
400 series (Client Error)
500 series (Server Error)

How do XML and JSON compare regarding functionality?
Correct : B
JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are both used for data interchange but have different characteristics:
Human Readability: JSON is often considered more human-readable because it is more concise and closely resembles the structure of programming languages like JavaScript.
Support for Arrays: JSON natively supports arrays, making it straightforward to represent lists of values. XML can represent arrays, but it does not do so natively and requires additional markup to represent arrays.
Data Mapping: XML provides extensive support for mapping data structures, including attributes and mixed content, making it suitable for complex data structures.
Data Types: JSON is lighter and provides sufficient data types for many applications (strings, numbers, objects, arrays, booleans, and null), whereas XML can be more verbose and supports a broader range of data types.
