False. It will appear the colour of the glass, but just a bit lighter. It’s like looking through floured water or a balloon
Answer: Cyber warfare is a real threat since being able to hack another computer especially a countries computer with lots of info in their weaknesses can lead to their downfall. Since they can even possibly if their skilled enough hack their entire data base system and leak it to the public and that wouldn't be good for them not in a single possible way. That's the reason it's dangerous not only that but also because they can access their servers; which can let them access anything online from the whole country including banking information military info which can let them know which area there gonna go to next equipment there gonna bring and where they're gonna launch missiles, bombs, even nukes if they decide to launch one. And being able to hijack the computer that launches the nukes can make the hacker launch the nuke to a different place or launch the nuke on the country trying to launch the nuke.

C. Unclustered index has the same ordering of data records as that of the data entries in the database
Explanation:
Indexes are used to split up queries in an SQL server or database management system DBMS.
There are two types of indexes namely clustered indexed and unclustered indexes.
Clustered indexes define the order in which data is stored in a table while unclustered index does not sort the order in a table.
In an unclustered index, the data table and the index are stored in different places, they are easy to maintain and update since they do not follow a particular order and there can be several indexes in a data file since the data table is stored differently from the index file.
So, all the other options except C are features of unclustered indexes since unclustered index does not have the same ordering of data records as that of the data entries in the database.
So, C is the answer.
