CRT-450 Exam Question 191

The Job_application_ c custom object has a field that is a master-detail relationship to the Contact object, where the Contact object is the master.
As part of a feature implementation, a developer needs to retrieve a list containing all Contact records where the related Account Industry is 'Technology', while also retrieving the Contact's Job_Application__c records.
Based on the object's relationships, what is the most efficient statement to retrieve the list of Contacts?

CRT-450 Exam Question 192

A developer writes a trigger on the Account object on the before update event that increments a count field. A record triggered flow also increments the count field every time that an Account is created or updated.

which three statements are accurate about debug logs?
Choose 3 answers

A.Debug log levels are cumulative, where FINE log level includes all events logged at the DEBUG, INFO, WARN, and ERROR levels.

B.The maximum size of a debug log is 5 MB.

C.Only the 20 most recent debug logs for a user are kept.

D.Debug logs can be set for specific users, classes, and triggers.

E.System debug logs are retained for 24 hours.

Correct Answer: A,B,E

Debug logs are used to track events that occur in an org, such as database operations, Apex code execution, workflow processes, and API calls. Debug logs have different categories, levels, and filters that determine what information is logged and how much detail is included. Some of the statements about debug logs are:
* Debug log levels are cumulative, where FINE log level includes all events logged at the DEBUG, INFO, WARN, and ERROR levels. This means that setting a higher log level for a category will also log the events from the lower levels. For example, if the log level for Apex Code is FINE, then the debug log will include log messages generated by DML statements, inline SOQL or SOSL queries, the start and completion of any triggers, and the start and completion of any test method.
* The maximum size of a debug log is 5 MB. Debug logs that are larger than 5 MB are reduced in size by removing older log lines, such as log lines for earlier System.debug statements. The log lines can be removed from any location, not just the start of the debug log.
* System debug logs are retained for 24 hours. Monitoring debug logs are retained for seven days. System debug logs are generated when you have active user-based trace flags, when you run Apex tests, and when executed code or API requests include debugging parameters or headers. Monitoring debug logs are generated when you set debug log filters for specific users, classes, and triggers.
The other statements are not accurate because:
* Only the 20 most recent debug logs for a user are kept. This is not true, because the number of debug logs that are kept for a user depends on the log size and the retention period. For example, if a user has
10 debug logs that are each 1 MB in size, and another user has 10 debug logs that are each 500 KB in size, then the first user will have more debug logs retained than the second user, even if they both generated the same number of logs.
* Debug logs can be set for specific users, classes, and triggers. This is partially true, but not entirely. You can set debug log filters for specific users, classes, and triggers, but you cannot set debug log levels for them. Debug log levels are set at the org level, and they apply to all debug logs that are generated in the org.
