Answer:
A PC such as a notebook computer.The evil twin gets the encrypted frame from the affected host,A VPN encrypts a frame with its own VPN key.
Explanation:
The evil twin after initial association when the victim client will establish a secure wireless connection with the victim client. The connection uses a key client-EF for encryption such that when the host transmits an encrypted frame it is transmitted to the evil twin. A VPN is an encrypted virtual private network used to access networks that are not trusted. The client encrypts a frame with a VPN key (Key Client-Server) which it shares with the server. The frame is further encrypted by the key it shares with the evil twin (Victim Client-ET) The evil twin will then receive a double encrypted frame. However, it will only be able to decrypt the Victim Client-ET key but not the VPN key hence it will not be able to read the message sent through the frame.
Answer:
Option (A) is the right answer.
Explanation:
According to the scenario, the user system is giving the error of invalid certificate while other users on the same network do not report any error, which means that there is some problem in a particular system.
Date and time can also be one of the main cause of this error because wrong date and time creates problem in surfing many websites by giving certificate error.
Hence the most appropriate answer is option (A).
While other option are wrong because of the following reasons:
- UEFI boot mode is mainly used in booting the operating system and has no connection with network.
- Logon time is also wrong because if the problem is with the login server, it can not give certificate error.
- User access control is also not correct because it is used to control the access of the user.
Answer:
A. Define boundaries
C. Deny access
D. Delay access
Explanation:
A barrier is a material or structure used to prevent or block access. Barriers can either be natural or structural and are used for many purposes usually for security reasons. The following are functions of barriers either natural or structural:
- Define areas of boundaries
- Delay or slow access. Example is the use of speed bumps to slow down vehicles.
- Provide access to entrances such as the use of gates
- Deny access to unauthorized personnel and allowing authorized personnel.

Answer:
return instruction used to return a value from a function.
Explanation:
Function is a block of statement which perform the special task.
Syntax for define a function:
type name(parameter_1, parameter_2,...)
{
statement;
return variable;
}
In the syntax, type define the return type of the function. It can be int, float, double and also array as well. Function can return the array as well.
return is the instruction which is used to return the value or can use as a termination of function.
For return the value, we can use variable name which store the value or use direct value.
