I thought all of them would work, surprised by C!

D looks fine to me, no errors there.

Wait, why would C cause an error?
JO

I agree, C is the one!

Option C will cause an error.

I’m leaning towards option E causing an error, but I can't quite remember why.
LE

I practiced a similar question, and I feel like option D should work since it joins on the IDs.

I'm not sure, but I remember something about aliases. Maybe option B is problematic?
SH

I think option C might cause an error because it references both tables but doesn't specify how they relate.

I've got a strategy here. Since the question is asking about two true statements, I'll methodically evaluate each option and eliminate the ones that are clearly false. That should help me narrow it down to the right answer.

Hmm, I'm a bit unsure about this one. The options all seem related to evaluating the supplier's quality capabilities, so I'll need to think through which one is the least relevant.

This is tricky, but I think the key is to remember that pairwise testing only requires us to cover all possible pairs of variable values, not every possible combination. So with 6 variables, 4 test cases should be sufficient to cover everything.

Okay, I think I've got this. The key is to configure the payment service for the cash and carry desk, so I'll go with option A.

The security test really emphasizes the need for an alternative path, so I might lean toward B too, but I feel uncertain about the details.

Hmm, I'm not sure about this one. I know Synapse has different components, but I'm not familiar with how they work with Cosmos DB. I'll have to think this through carefully.

Hey, at least they didn't throw in a table called 'sample3' just to mess with us. That would be too much, even for a certification exam!

User 3: I agree, the tables don't have the same columns.
JO

Yeah, that makes sense. Option D is the one that will cause an error.

User 2: I think option D will cause an error.
LO

User 1: Yeah, that would be too confusing.
RA

I agree, the error would occur because there is no 'data' column in sample2.
MA

I think option D will cause an error.
FE

Hmm, Option C is a bit tricky. Trying to select data where the IDs don't match? That's gotta be a problem.
FA
Fabiola

I'm going with Option E. Selecting from both tables where the IDs match, and including the data column. Looks good to me!
AN
Andree

I agree, Option D is the one that would cause an error. It's important to be specific when joining tables.
TA
Tarra

You're right, Option D would cause an error. It doesn't specify which id to match on between the two tables.
LE
Lenna

I think Option D would cause an error because it selects id and data from sample1 and sample2 without specifying which id to match on.
MA
Margarita
1 year ago
Option E is correct. It selects the id and data from sample1 where the id matches in sample2.
EL
Elina
1 year ago
Great choice! Option E is the correct SQL statement that will not cause an error.
LA
Lasandra
1 year ago
I agree. Option E is the only statement that includes both tables and the data column.
KE
Keith
1 year ago
That makes sense. Option E is the only one that joins the tables on the ID column.
CH
Chauncey

Option E is correct. It selects from both tables where the IDs match and includes the data column.
KA
Kattie

Hold up, I think Option D might be the one. Trying to select from both tables where the IDs match, but the data column doesn't exist in sample2.
AZ

User 2: Yeah, that makes sense. Option D is the one that will cause an error.
CH
Charlette

User 1: I think you're right, Option D will cause an error because data column doesn't exist in sample2.
VI
Vivan

Option A seems straightforward enough. Why would that cause an error?
ST
Stephaine

Option D is correct as it selects id and data columns from sample1 and sample2 where their ids match.
LA
Lanie
1 year ago
Option C will cause an error because it tries to select the data column from sample1 which does not exist.
RE
Reyes

Option B is also correct as it uses an alias for the table sample1.
HE
Herman

Option A is correct because it selects the id column from sample1 without any issues.
