MENDIX ADVANCED CERTIFICATION 2 FINAL
REVIEW 2026 FULL ANSWERS
◉ The Communication between the Mendix Runtime and Database
Server:
A. Always takes a distinct form when using a mobile device instead
of a desktop device to access an app.
B. Needs to be manually triggered by the Mendix developer at all
times.
C. Includes communication between the supported database servers
using JDBC.
D. Is fully based on proprietary protocols and can never be examined
in case of issues Answer: C. Includes communication between the
supported database servers using JDBC.
◉ What is NOT an advantage of using the database source option
versus the XPath option?
A. The database source option can be used to specify constraints that
span entities.
B. The database source option does not require understanding of
XPath.
C. Constraints can be specified much easier and with a lot of
guidance by the Modeler.
,D. The database source option is also available on pages that need to
be available in offline mode. Answer: A. The database source option
can be used to specify constraints that span entities.
◉ When you want to show a list of shipped orders, will the Database
data source generate a different request than the XPath data source
option?
A. Yes, when using the database data source, data will always be
retrieved from the local device.
B. No, the database data source will always lead to the same request
as the XPath data source.
C. Yes, the database data source relies on a different request protocol
than the XPath data source.
D. No, Mendix Runtime will analyze the data source, and will try to
parse it in the same request Answer: B. No, the database data source
will always lead to the same request as the XPath data source.
◉ Which of the following is not a possible source of data for a
microflow?
A. An object retrieved from the database using a retrieve action.
B. A variable passed as input parameter by another microflow.
C. A page passed as input parameter by another microflow.
D. An object received as input parameter from another microflow.
Answer: C. A page passed as input parameter by another microflow.
, ◉ True or false: by association will always be an in-memory retrieve.
A. False, if objects aren't available in memory, a retrieve by
association will automatically result in a database retrieve.
B. True, technically, a retrieve by association cannot result in a query
on the database.
C. True, associated objects are always available in memory, therefore
it is always an in-memory retrieve.
D. False, a retrieve by association will always retrieve the objects
from the database directly, to maintain data consistency. Answer: A.
False, if objects aren't available in memory, a retrieve by association
will automatically result in a database retrieve.
◉ Is there ever a reason to retrieve an object from database instead
of over association?
A. Yes, retrieving from the database makes sure that all the
configured entity access rules are applied.
B. Yes, in cases where constraints other than a single association are
applicable or where stored database values are required.
C. No, by retrieving over association the object will be retrieved from
the object cache (if available), which improves performance.
D. No, retrieving from database will exhibit the same behavior as
retrieving over association if the object is retrievable over
association. Answer: B. Yes, in cases where constraints other than a
single association are applicable or where stored database values
are required.
