Question#1

UC has millions of case records with case history and SLA data. UC’s compliance team would like historical cases to be accessible for 10 years for Audit purpose.
What solution should a data architect recommend?

A. Archive Case data using Salesforce Archiving process

B. Purchase more data storage to support case object

C. Use a custom object to store archived case data.

D. Use a custom Big object to store archived case data.

Explanation:
The best solution to store historical cases for 10 years for audit purpose is to use a custom Big object to store archived case data. Big objects are a type of custom object that can store massive amounts of data on the Salesforce platform without affecting performance or storage limits. They also support point-and-click tools, triggers, and Apex code. Big objects can be used for archiving historical data that needs to be retained for compliance or analytics purposes3. Archiving case data using Salesforce Archiving process is not a good option because it only supports archiving cases that are closed for more than one year, and it does not allow customizing the archival criteria or accessing the archived data via Apex or APIs4. Purchasing more data storage to support case object is expensive and may impact performance. Using a custom object to store archived case data is not scalable and may consume a lot of storage space.

Question#2

Universal Containers has multiple systems all containing and maintaining customer data. Although point-to-point integrations are in place, customers are complaining about consistency in the data.
What solution should the data architect recommend?

A. Improve existing point-to-point integrations

B. Data cleanse each system

C. Perform a onetime synchronization to level set the built up inconsistencies

D. An MDM solution as the customer master, with centralized integrations to ensure consistency across all systems.

Explanation:
Master data management (MDM) is a solution that helps organizations manage their master data across multiple systems and ensure consistency and quality. An MDM solution can act as the customer master, with centralized integrations to other systems, to avoid data duplication and inconsistency.

Question#3

Get Cloudy Consulting needs to evaluate the completeness and consistency of contact information in Salesforce. Their sales reps often have incomplete information about their accounts and contacts. Additionally, they are not able to interpret the information in a consistent manner. Get Cloudy Consulting has identified certain ""key"" fields which are important to their sales reps.
What are two actions Get Cloudy Consulting can take to review their data for completeness and consistency? (Choose two.)

A. Run a report which shows the last time the key fields were updated.

B. Run one report per key field, grouped by that field, to understand its data variability.

C. Run a report that shows the percentage of blanks for the important fields.

D. Run a process that can fill in default values for blank fields.

Explanation:
Running a report that shows the last time the key fields were updated can help Get Cloudy Consulting identify stale or outdated data and prioritize data cleansing activities. Running a report that shows the percentage of blanks for the important fields can help Get Cloudy Consulting measure the completeness of their data and identify gaps or missing value

Question#4

Universal Containers has a custom object with millions of rows of data.
When executing SOQL queries, which three options prevent a query from being selective? (Choose three.)

A. Using leading % wildcards.

B. Using trailing % wildcards.

C. Performing large loads and deletions.

D. Using NOT and != operators.

E. Using a custom index on a deterministic formula field.

Explanation:
Using leading % wildcards, performing large loads and deletions, and using NOT and != operators are three options that prevent a query from being selective. These options can cause the query to scan a large number of records or indexes, which can negatively impact the performance and scalability of the query5. Using a custom index on a deterministic formula field, on the other hand, can improve the query selectivity by allowing the query to use the index instead of scanning all the records6.

Question#5

Low Value
Which strategy should a data architect recommend to configure customer type?

A. Lookup to a custom object with defined choices.

B. Single-select restricted picklist with defined choices.

C. Provide help text to guide users with defined choices.

D. Create a validation rule to limit entry to defined choices.

Explanation:
single-select restricted picklist with defined choices can be a way to configure customer type. The article states that picklists are fields that allow users to select one or more predefined values from a list, and restricted picklists ensure that users can only select from the defined values. This can help to limit the choices for customer type and ensure data quality.
