Alteryx full mock exam
12 questions sampled across all 4 modules. Timed like the real thing: answer everything, then review the explanations.
How do you see the data mid-workflow?
- Run and export
- Click the connection between two tools
- Open the source file
- Add a Browse tool only
Answer: Click the connection between two tools — Any connection shows a preview and record count.
Which is the most important thing to check after a Join?
- Field order
- The record count
- Colours
- Tool position
Answer: The record count — A changed record count is the usual sign of a fan-out or lost rows.
Your workflow duplicated all its data on the second run. Cause?
- A Join issue
- Output set to Append to existing
- Wrong delimiter
- A Browse tool
Answer: Output set to Append to existing — Use delete-and-append or overwrite when reruns are possible.
Which type should hold a currency amount?
- Double
- Fixed Decimal
- Float
- V_String
Answer: Fixed Decimal — Floating point accumulates rounding error across many rows.
[Revenue] - [Discount] returns null on some rows because:
- Wrong type
- Discount is null on those rows
- The field is too small
- Formula order
Answer: Discount is null on those rows — Guard with IsNull or use Data Cleansing.
Why attach a Browse to the Filter F output?
- To improve speed
- To see what was excluded and verify the condition
- It is required
- To sort the data
Answer: To see what was excluded and verify the condition — Silent over-filtering is a common defect.
Which anchor holds rows that matched on both sides?
- L
- J
- R
- All three
Answer: J — J is the inner join result.
Union set to "by position" with differently ordered columns:
- Errors
- Silently puts values in the wrong fields
- Matches by name anyway
- Drops the file
Answer: Silently puts values in the wrong fields — Use by name unless you have a specific reason.
Your Cross Tab columns are in the wrong order because:
- A bug
- Cross Tab sorts new columns alphabetically
- Wrong aggregation
- Missing Sort tool
Answer: Cross Tab sorts new columns alphabetically — Prefix with a number before pivoting.
How do you test a workflow without running one branch?
- Delete the tools
- Disable the container holding them
- Add a Filter
- Comment them out
Answer: Disable the container holding them — Disabling skips everything inside on the next run.
A field holds "widget, bolt, nut" and you need one row each. Use:
- RegEx Match
- Text to Columns, split to rows
- Cross Tab
- Append Fields
Answer: Text to Columns, split to rows — Splitting to rows is the option people overlook.
To produce one CSV per region in a single run:
- One workflow per region
- Take File/Table Name From Field on the Output tool
- A Union tool
- A container per region
Answer: Take File/Table Name From Field on the Output tool — The field value becomes the file name.
