This DA0-001 practice question tests your understanding of visualizing data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An analyst creates a pie chart showing market share of four companies: A (45%), B (30%), C (15%), D (10%). A stakeholder complains that it is difficult to compare C and D. Which alternative chart should the analyst recommend?
Horizontal bar chart
Horizontal bar chart allows easy length comparison between categories.
Line chart
Why wrong: Line chart is for trends, not for comparing discrete categories.
Stacked bar chart
Why wrong: Stacked bar shows part-to-whole like pie, still hard to compare subcomponents.
Scatter plot
Why wrong: Scatter plot is for relationships, not for comparing category values.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Horizontal bar chart
A bar chart allows easier comparison of individual values, especially when differences are small. The pie chart's reliance on angles makes small slices hard to compare. Options A, B, and D are not as effective for comparing discrete values.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Horizontal bar chart
Why this is correct
Horizontal bar chart allows easy length comparison between categories.
Related concept
Static NAT maps one inside address to one outside address.
Line chart
Why it's wrong here
Line chart is for trends, not for comparing discrete categories.
Stacked bar chart
Why it's wrong here
Stacked bar shows part-to-whole like pie, still hard to compare subcomponents.
Scatter plot
Why it's wrong here
Scatter plot is for relationships, not for comparing category values.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
Stacked bar shows part-to-whole like pie, still hard to compare subcomponents.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DA0-001 NAT questions on configuration and troubleshooting.
