Data Storage Quiz

What does "capacity" refer to in the context of data storage?

• The speed of data retrieval

• The size of the container needed to store data

• The type of data being stored

• The number of users accessing the data

Answer explanation

In the context of data storage, 'capacity' refers to the size of the container needed to store data, not the speed of data retrieval, type of data, or number of users accessing the data.

In data storage, which of the following is the largest unit of data?

• Kilobytes (KB)

• Megabytes (MB)

• Terabytes (TB)

• Gigabytes (GB)

Answer explanation

In data storage, the largest unit of data is Terabytes (TB), which is greater than Kilobytes (KB), Megabytes (MB), and Gigabytes (GB).

Which factor most influences current capacity requirements?

• Data growth rate

• Data volume

• Data security

• Data accessibility

Answer explanation

Data growth rate is the factor that most influences current capacity requirements as it determines the rate at which data is being generated and stored, impacting the overall capacity needed.

How does the data retention period affect capacity requirements?

• It has no impact

• Longer retention requires more capacity

• Shorter retention requires more capacity

• It only affects data growth rate

Answer explanation

Longer retention periods require more capacity because more data needs to be stored for a longer duration.

What does "scalability" refer to in network storage?

• Speed of data retrieval

• The ability to adjust storage capacity as needed

• Type of data being stored

• Data security measures

Answer explanation

In network storage, scalability refers to the ability to adjust storage capacity as needed, allowing for flexibility and expansion based on requirements.

Which is an example of scalability in storage solutions?

• Adding more hard drives

• Limiting access to data

• Reducing data volume

• Ignoring data growth rate

Answer explanation

Adding more hard drives is an example of scalability in storage solutions as it allows for increased storage capacity without changing the entire system.

How does data retrieval speed impact operational efficiency?

• It has no effect

• Slower retrieval improves efficiency

• Faster retrieval improves efficiency

• It only affects user experience

Answer explanation

Faster retrieval improves efficiency

What does "user authentication" ensure in data accessibility?

• Swift decision-making

• Timely updates

• Only authorised individuals access data

• Global accessibility

Answer explanation

User authentication ensures that only authorised individuals can access data, enhancing data security and privacy.

What does the mobile accessibility of a network refer to?

• Global accessibility

• Access from smartphones and tablets

• Access control mechanisms

• Scalability features

Answer explanation

The mobile accessibility of a network refers to access from smartphones and tablets, making it easier for users to connect and interact with the network using their mobile devices.

What potential security concern is more common with on-premises (local) data storage?

• Geographical location issues

• Data privacy breaches

• Vendor lock-in

• Service Outages

Answer explanation

Geographical location issues are more common with on-premises data storage, posing potential security concerns related to physical access and disaster recovery.
