Answer 1

Expert Solution & Answer

Chapter 17, Problem 1MC

Program Description Answer

When instantiating a generic class, only reference type arguments are passed to the type parameters.

Hence, the correct answer is option “B”.

Expert Solution & Answer

Explanation of Solution

Reference types only:

Only non-primitive types can be substituted for type parameters when creating instances for generic class.
Reference types are non-primitive types.
The compiler autoboxes the primitive type values to reference types.

Explanation for incorrect options:

a. Primitive types only:

When creating instances for a generic class, only non-primitive types can be substituted for type parameters.

Hence, the option “A” is wrong.

c. Interface types only:

The type parameters can be specified as interface type but the arguments passed to type parameters at the time of instantiation, must be real types such as Integer, String, and so on.

Hence, the option “C” is wrong.

d. Primitive, reference, and interface types:

When creating instances for a generic class, only reference types can be substituted for type parameters.

Hence, the option “D” is wrong.

Objective: The objective of this assignment is to gain practice with pen testing a live web application running on a remote server. The live web application is a known vulnerable web application called DVWA (Damn Vulnerable Web Application) with security settings set to low. The web app is running on an AWS EC2 (Elastic Compute Cloud) instance running Ubuntu 22. Note: The point of this assignment is to step it up a notch, we learnt about different web application vulnerabilities and applied that knowledge, now we are going to pen test and enumerable the vulnerabilities of a web app + the underlying infrastructure it is running on. Before you begin please find out what your IP address is and place it in this sheet so that I can track who is doing what: IP Addresses.docx . Tasks: 1- Start by connecting to the target, I did not install a TLS certificate on purpose that is why you are going to connect via http and not via https: http://3.99.221.134/dvwa/login.php 2- Broken Authentication:…
