A data architect needs to efficiently prepare a data model for a meeting in an hour.
The data source to be used contains five date fields. The app needs to display sales trends and compare the current year to date (CYTD) to last year to date (LYTD). The app is NOT going to be published. It will only be used for this meeting and a single user's ad-hoc analysis.
What should the data architect do to meet these requirements?

• A.Create a canonical calendar
• B.Use the data manager
• C.Create five master calendars
• D.Load a calendar island

Refer to the exhibit.

The Section Access security table for an app is shown User ABC\PPP opens a Qlik Sense app with a table using the field called LEVEL on one of the table columns What is the result?

• A.The user gets a "Field not found" error
• B.The table is removed from the user interface
• C.The user gets an "Invalid visualization" error
• D.The table is displayed without the LEVEL column

A data architect needs to load large amounts of data from a database which is continuously updated New records are added, and existing records get updated and deleted. Each record has a LastModified field All existing records are exported into a QVD file. The data architect wants to load the records into Qlik Sense efficiently.
Which steps should the data architect take to meet these requirements?

• A.1. Use a partial load to load new and updated data from the database.
  2. Load the existing data from the QVD without the updated rows that have just been loaded from the database. Concatenate with the new and updated records.
  3. Use the Peek function to remove the deleted rows.
• B.1. Load the existing data from the QVD.
  2. Load new and updated data from the database. Concatenate with the table loaded from the QVD.
  3. Create a separate table for the deleted rows and use a WHERE NOT EXISTS to remove these records.
• C.1. Load the new and updated data from the database
  2. Load the existing data from the QVD without the updated rows that have just been loaded from the database. Concatenate with the new and updated records.
  3. Load all records from the key field from the database and use an Inner Join on the previous table.
• D.1. Load the existing data from the QVD.
  2. Load the new and updated data from the database without the rows that have just been loaded from the QVD. Concatenate with data from the QVD.
  3. Load all records from the key field from the database and use an Inner Join on the previous table.

Users of a published app report incomplete visualizations. The data architect checks the app multiple times and cannot replicate the error. The error affects only one team What is the most likely cause?

• A.The affected users were NOT added to the Section Access table
• B.A security rule has been applied to the sheet object
• C.Section access restricts too many records
• D.An Omit field has been applied

A data architect needs to create an app to analyze 30-day re-admissions at a hospital.
* The medical record system does NOT calculate re-admission data
* The business rule to follow: if a patient is admitted to a hospital within 30 days after being discharged from a previous hospital stay, that event should be captured in the app with a flag called "30-day Re-admission"
* Data being used from the patient record includes hospital account ID, patient ID, admission dater and discharge dateWhich action should the data architect perform first to meet these requirements?

• A.Sequence patient records by hospital account ID and patient ID using the Peek function
• B.Calculate the days since previous discharge using admission date and discharge date
• C.Order patient records by patient ID and admission date
• D.Sequence patient records by patient ID using the Peek function
