Which of the following is a characteristic of all non-relational databases?

Show Suggested Answer Hide Answer
Suggested Answer: C

The option that is part of logical database infrastructure security is perimeter network. Perimeter network, also known as DMZ (Demilitarized Zone), is a network segment that lies between an internal network and an external network, such as the internet. Perimeter network provides an additional layer of security for the internal network by isolating and protecting the servers or services that are exposed to the external network, such as web servers, email servers, database servers, etc. Perimeter network also helps prevent unauthorized access or attacks from the external network to the internal network by using firewalls, routers, proxies, etc. The other options are either part of physical database infrastructure security or not related to database infrastructure security at all. For example, surveillance is a method of monitoring and recording physical activities or events in a location or resource; biometric access is a device that uses biological characteristics to control access to a physical location or resource; cooling system is a device or system that regulates the temperature and humidity of a location or resource.Reference:CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.1 Given a scenario, implement database infrastructure security.

I thought non-relational meant no strict schema at all!

I definitely recall that non-relational databases can handle various data types, but I’m not sure if they all deal with unstructured data specifically.

I’m a bit confused about the term "logical record groupings." I feel like that might apply to some non-relational databases, but not all of them.

I remember practicing a question about database schemas, and I think non-relational ones don't follow a strict tabular schema like relational databases do.

I think non-relational databases are often associated with unstructured data, but I'm not completely sure if that's true for all of them.

I'm a bit confused on this one. I know non-relational databases are more flexible than SQL databases, but I'm not sure if unstructured data is the only defining characteristic. I'll have to review my notes to be sure.

I think the answer is B as well. Non-relational databases are known for being able to store and process unstructured data, which is a key differentiator from relational databases with their rigid table structures.

Hmm, I'm a little unsure about this one. I know non-relational databases are different from traditional SQL databases, but I can't quite remember all the key characteristics. I'll have to think this through carefully.

I'm pretty sure the answer is B - unstructured data. Non-relational databases like NoSQL are designed to handle unstructured data that doesn't fit neatly into rows and columns.

This is a good one. I know the `strpos()` function well, and the third parameter is just telling it to start the search at the 2nd character. I'm confident I can get the right answer here.

I see your point, Anika. But I think C) Logical record groupings is the correct answer because non-relational databases focus on organizing data in a more flexible way.
