Quick Answer
The answer is an area chart, specifically a stacked area chart, because it is the best visualization for comparing the proportion of each error type to the total errors over time. This works because the stacked area chart fills the space between the line and the baseline, with each segment representing a part of the whole, allowing you to see both the trend of the total and how each category’s share changes across a continuous timeline. On the Splunk Core Certified Power User SPLK-1003 exam, this question tests your understanding of when to use area charts versus column, line, or pie charts—a common trap is choosing a pie chart, which shows proportions but cannot display change over time, or a line chart, which only shows magnitude, not proportion. Remember the memory tip: “Area stacks the parts to show how the whole grows or shrinks over time.”
This SPLK-1003 practice question tests your understanding of advanced visualization and lookups. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Which visualization type is best for comparing the proportion of each error type to the total errors over time?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Pie chart (with multiple series)
Why wrong: Pie chart is for a single point in time, not over time.
Column chart
Why wrong: Column chart can show proportions if stacked, but area chart is more suitable for time series.
Line chart
Why wrong: Line chart shows trends, not proportions.
Area chart
Stacked area chart effectively shows proportion over time.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Area chart
Option D is correct because an area chart (especially stacked) shows proportions over time. Option A (column) can be used but area is more common for proportion over time. Option B (line) does not show proportion. Option C (pie) is not time-based.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Pie chart (with multiple series)
Why it's wrong here
Pie chart is for a single point in time, not over time.
Column chart
Why it's wrong here
Column chart can show proportions if stacked, but area chart is more suitable for time series.
Line chart
Why it's wrong here
Line chart shows trends, not proportions.
Area chart
Why this is correct
Stacked area chart effectively shows proportion over time.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
OSPF neighbours must agree on key parameters.
Common exam traps
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Trap categories for this question
Command / output trap
Column chart can show proportions if stacked, but area chart is more suitable for time series.
Detailed technical explanation
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
A practitioner preparing for the SPLK-1003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
What to study next
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related SPLK-1003 OSPF questions on adjacency and route selection.
