The concept of providing on-demand network access to shared pools of configurable computing resources is known as _______.
- Big Data
- Cloud Computing
- IoT
- Quantum Computing
'Cloud Computing' is the concept of delivering on-demand access to a shared pool of computing resources over the internet. These resources can be easily configured and scaled to meet various computing needs.
The _______ field in an IPv4 header determines the priority of the packet.
- DSCP
- IP Address
- Protocol
- TTL
The 'DSCP' (Differentiated Services Code Point) field in an IPv4 header is used to determine the priority and class of service for the packet, allowing for quality of service (QoS) differentiation in IP networks.
A company wants to test its security posture from both inside and outside the organization without its IT team's prior knowledge. What type of penetration test should it conduct?
- Black Box
- Grey Box
- Red Team
- White Box
The company should conduct a 'Red Team' penetration test. A Red Team simulates real-world attacks, attempting to breach security measures with no prior knowledge. This type of test is comprehensive and helps identify vulnerabilities from both inside and outside the organization, providing valuable insights.

In data visualization, which type of chart is best suited for showing the distribution of a single continuous variable?
- Bar Chart
- Histogram
- Line Chart
- Pie Chart
A 'Histogram' is ideal for displaying the distribution of a single continuous variable. It divides the data into intervals or bins and shows the frequency or count of data points within each bin, giving insights into the data's distribution.
In which sorting algorithm are repeated swaps made to bring elements to their correct position, typically visualized like "bubbles" moving up in a fluid?
- Bubble Sort
- Insertion Sort
- Merge Sort
- Quick Sort
'Bubble Sort' is an elementary sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. The largest unsorted element "bubbles up" to its correct position.
