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'm going with B) Unstructured data. That's the key characteristic that sets non-relational databases apart from their relational counterparts.

Haha, this one's a real head-scratcher! I bet the correct answer is something like 'all of the above, and also the kitchen sink'.

Hmm, I was thinking it was D) Tabular schema, but now I'm second-guessing myself. Non-relational databases are known for their flexible data models, right?

Non-relational databases can have flexible data models, so D) Tabular schema is not always a characteristic.

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.

I disagree, I believe it's B) Unstructured data because non-relational databases can handle various data types.

I'm pretty sure it's B) Unstructured data. Non-relational databases are designed to handle data that doesn't fit neatly into rows and columns.

I think it's D) Tabular schema. Non-relational databases don't follow the traditional tabular structure.
