Discuss Snowflake ARA-C01 Exam Topic 1 Question 52

Which feature provides the capability to define an alternate cluster key for a table with an existing cluster key?

AExternal table

BMaterialized view

CSearch optimization

DResult cache

Suggested Answer: B

A materialized view is a feature that provides the capability to define an alternate cluster key for a table with an existing cluster key. A materialized view is a pre-computed result set that is stored in Snowflake and can be queried like a regular table. A materialized view can have a different cluster key than the base table, which can improve the performance and efficiency of queries on the materialized view. A materialized view can also support aggregations, joins, and filters on the base table data.A materialized view is automatically refreshed when the underlying data in the base table changes, as long as the AUTO_REFRESH parameter is set to true1.

Not sure about that, seems too good to be true!

Robt 10 months ago

Wait, can you really change the cluster key like that?

Lucia 10 months ago

I thought it was C, search optimization.

Aliza 10 months ago

Agreed, B is the right answer!

Cherry 11 months ago

It's definitely B, materialized view!

Marta 11 months ago

Result cache seems unrelated to cluster keys, but I could be wrong. I should have reviewed that section more thoroughly!

Olive 11 months ago

I feel like external tables could be the right choice, but I also have a nagging doubt about whether they actually support alternate cluster keys.

Lashon 11 months ago

I remember practicing a question about cluster keys, and I think search optimization was mentioned, but I can't recall if it applies here.

Yuette 11 months ago

I think the answer might be related to materialized views, but I'm not entirely sure if they allow for alternate cluster keys.

Hortencia 12 months ago

Ah, I think I've got it. The key here is that the question is asking about defining an alternate cluster key, not just a regular index. I'm going with B, materialized view.

Staci 12 months ago

I'm a bit confused on this one. I'm not sure which feature would specifically allow you to change the cluster key of an existing table. I'll have to review my notes.

Markus 12 months ago

I'm pretty confident the answer is B. Materialized views allow you to define an alternate index structure, which could include a different cluster key.

Clarinda 1 year ago

Okay, let me see. I know materialized views can provide an alternate way to access data, but I'm not sure if that's the right answer here.

Donte 1 year ago

Hmm, this seems like a tricky one. I'll need to think through the different database features and how they relate to cluster keys.

Gianna 1 year ago

I'm going to go with B) Materialized view. It's the only option that seems to fit the description of defining an alternate cluster key. Unless, of course, this is all just a clever ruse to make us look foolish. In which case, I'll just laugh it off and order another coffee.

User1: I think B) Materialized view is the right choice.

Raina 1 year ago

That makes sense, I see how search optimization could be the correct answer.

Nettie 1 year ago

I think the answer is C) Search optimization because it allows for defining alternate cluster keys for better performance.

Mel 1 year ago

C) Search optimization? Hmm, maybe they're trying to throw us off with that one. But I'm going with B) Materialized view. Sounds like the right feature for the job.

But external tables are used to load data from external sources, not for defining alternate cluster keys.

Dorothea 1 year ago

A) External table? Nah, that's for accessing data outside the database. This is clearly about managing the data structure within the database.

Laura 1 year ago

D) Result cache? Really? That's not even close. This question is testing our understanding of database features, not our ability to guess randomly.

A) External table

Raina 1 year ago

I disagree, I believe the answer is B) Materialized view.

Lashaun 1 year ago

I think the answer is B) Materialized view. It allows you to define a new index that can be used as an alternate cluster key.

Mee 1 year ago

I think it might be Search optimization, as it can help improve the performance of queries by optimizing the search process.

I agree, Materialized view allows you to define a new index as an alternate cluster key.

I'm not sure, but I think it could be A) External table.
