Answer:

Option (D) is the right answer.

Explanation:

DHCP term used as a short form of dynamic host configuration protocol, which is used to assigns the IP address automatically according to the network.

According to the scenario, the system is getting the wrong IP address that resulting in internet disconnection which is a failure of the DHCP server because it is responsible for assigning the right IP address to the system.

Hence option (D) is the most appropriate answer.

While other options are wrong because of the following reasons:

Static IP is the type of IP address which is fix and doesn't change in the system after rebooting, hence it has no connection in the change of IP address.

If the DHCP server is working well there is no chance of interference from the surrounding device.

Network setting has no connection with computer power supply as SMPS is used to give power and boot system only.

IgorLugansk [536]

Answer: Online analytical processing

Explanation:

Online analytical processing(OLAP) is the method through which multi-dimension analytical queries can be resolved.User can attain selected query data as per their selection and then assess and analyze them from different view point.

It helps in viewing and reporting , planning ,performing analytical calculation, collecting data in data cubes etc.
Other options are incorrect because data adjacency, Ad hoc reporting ,data segregation and E-discovery are not the mechanism through which query and storage of data in data cubes take place.
Thus, the correct option is online analytical processing

A production line at a beverage company has installed a program that uses a series of statements that perform a specific task. T

MatroZZZ [7]

Since the program is set in such a way that the functions are called directly from the main function multiple times and there is no special mention of any class or object, the type of programming language used by the production line is a structured programming language.

<u>Explanation:</u>

In a structured programming language, all the tasks are performed by different functions.

There are no things such as classes, objects, and access specifiers in structured programming and importance are given to functions and sequences of actions to be taken.

Another name for structured programming is procedure-oriented programming. It follows a top-down approach.
