Quick Answer
The answer is SELECTEDVALUE and CONCATENATEX. SELECTEDVALUE returns the single selected year from a slicer or filter context, making it ideal for a dynamic title that displays the currently selected year, while CONCATENATEX allows you to combine multiple selected years into a single text string when more than one year is chosen. On the Microsoft Power BI Data Analyst PL-300 exam, this tests your understanding of scalar functions versus table functions and how to handle single versus multiple selections in report titles—a common trap is confusing SELECTEDVALUE with DISTINCT, which returns a table, not a scalar. Remember the memory tip: “SELECTEDVALUE for one, CONCATENATEX for none or many” to avoid picking SUM or CALCULATE, which are mathematical or filter modifiers, not text generators.
This PL-300 practice question tests your understanding of visualize and analyze the 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.
Which TWO DAX functions can be used to create a dynamic title that shows the currently selected year in a report, assuming a date table with a Year column?
SUM('Date'[Year])
Why wrong: SUM aggregates numbers, not suitable for text.
DISTINCT('Date'[Year])
Why wrong: Returns a table, not scalar.
CONCATENATEX(VALUES('Date'[Year]), 'Date'[Year], ", ")
Joins multiple selected years into a string.
SELECTEDVALUE('Date'[Year])
Returns the single selected year value.
CALCULATE(VALUES('Date'[Year]))
Why wrong: CALCULATE with VALUES returns a table, not scalar.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
CONCATENATEX(VALUES('Date'[Year]), 'Date'[Year], ", ")
Options A and C are correct. SELECTEDVALUE returns the single selected value from a column; if multiple values are selected, it returns blank or a default. CONCATENATEX can be used to combine multiple selected years into a string. Option B is wrong because CALCULATE does not return a text value. Option D is wrong because SUM is mathematical. Option E is wrong because DISTINCT returns a table, not a scalar.
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.
SUM('Date'[Year])
Why it's wrong here
SUM aggregates numbers, not suitable for text.
DISTINCT('Date'[Year])
Why it's wrong here
Returns a table, not scalar.
CONCATENATEX(VALUES('Date'[Year]), 'Date'[Year], ", ")
Why this is correct
Joins multiple selected years into a string.
Related concept
Static NAT maps one inside address to one outside address.
SELECTEDVALUE('Date'[Year])
Why this is correct
Returns the single selected year value.
Related concept
Static NAT maps one inside address to one outside address.
CALCULATE(VALUES('Date'[Year]))
Why it's wrong here
CALCULATE with VALUES returns a table, not scalar.
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.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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 PL-300 NAT questions on configuration and troubleshooting.
