[All Databricks Certified Data Engineer Associate Questions]

A data engineer is running code in a Databricks Repo that is cloned from a central Git repository. A colleague of the data engineer informs them that changes have been made and synced to the central Git repository. The data engineer now needs to sync their Databricks Repo to get the changes from the central Git repository.

Which of the following Git operations does the data engineer need to run to accomplish this task?

AMerge

BPush

CPull

DCommit

EClone

Show Suggested Answer

Suggested Answer: D

To include a property indicating that a table contains personally identifiable information (PII), the TBLPROPERTIES keyword is used in SQL to add metadata to a table. The correct syntax to define a table property for PII is as follows:

CREATE TABLE customersInFrance

USING DELTA

TBLPROPERTIES ('PII' = 'true')

SELECT id,

firstName,

lastName

FROM customerLocations

WHERE country = 'FRANCE';

The TBLPROPERTIES ('PII' = 'true') line correctly sets a table property that tags the table as containing personally identifiable information. This is in accordance with organizational policies for handling sensitive information.

I thought Commit was for saving changes locally, not syncing.

No way, you just need to Pull, not Clone or Push.

Wait, isn't Merge also a valid option sometimes?

You need to run a Pull to sync changes.

I feel like Commit is about saving local changes, so it can't be the answer here.

I'm a bit confused; I thought Merge was for combining changes, not for syncing.

I remember practicing a similar question, and I think Pull is the right choice since it fetches and merges changes.

I think we need to use the Pull operation to get the latest changes from the central repository, but I'm not entirely sure.

Hmm, I'm not entirely sure about this one. I know Pull is used to fetch changes from a remote repository, but could Merge also be an option here? I'll have to think about this a bit more before deciding.

This is a classic Git scenario. The data engineer needs to pull the changes from the central repo to their local Databricks Repo. That's the most straightforward way to sync the two. I'm confident C. Pull is the right answer here.

I'm a bit confused here. Is it really that simple? Shouldn't the data engineer also consider merging the changes or something? I'm not sure, maybe I'm overthinking this. I'll go with C. Pull for now.

Okay, let me think this through. If the colleague has already made changes and synced them to the central repo, then the data engineer needs to pull those changes to their local repo. So I'm going to go with C. Pull.

Hmm, this seems straightforward. I think the answer is C. Pull would be the right operation to sync the local Databricks Repo with the changes in the central Git repository.

I'm a bit confused by the options here. I thought we needed to use the `renderAs` attribute, but some of these options mention `readerAs` and `contentype`. I'll have to double-check the Visualforce documentation to be sure.

E) Clone? What, is the data engineer going to create a whole new repo just to get the latest changes? That's like using a sledgehammer to crack a nut.

B) Push? Really? Who would push to the remote repo when they need to pull the changes? C) Pull is the only sensible option here.

Hmm, I was tempted to choose A) Merge, but that's usually for resolving conflicts, not just syncing. C) Pull is the correct answer, no doubt about it.
