https://www.certsquestions.com/1Z0-771-pdf-dumps.html
 Use SSL/TLS for secure communication and implement custom authentication and authorization logic

Correct Answer: C

Explanation/Reference:

Option 1: Incorrect. OAuth 0 is primarily used for client applications to obtain authorization to access protected resources on

behalf of a user. It is not the recommended approach for handling authentication and authorization in a RESTful web service.

Option 2: Incorrect. Basic Authentication relies on sending a username and password in the request headers, which can be

easily intercepted. It is not the recommended approach for handling authentication in a RESTful web service. Additionally,

implementing custom authorization logic can be error-prone and difficult to maintain. Option 3: Correct. JSON Web Tokens

(JWT) provide a secure and stateless method for authenticating and authorizing requests in a RESTful web service. JWT allows

for the integrity and authenticity of messages to be verified and provides a way to securely transmit information between

parties. Option 4: Incorrect. SSL/TLS is used for securing communication between the client and server, but it does not handle

authentication or authorization. Implementing custom authentication and authorization logic can be error-prone and difficult to

maintain

solution guarantees that any changes to the master theme are reflected in the copied theme?

Option A : Refreshing the templates

Option B : Verifying the theme subscription
Option C : Subscribing the copied theme to the master theme and refreshing the theme
Option D : Copying the changes made in the master theme to the copied theme

Correct Answer: C

https://www.certsquestions.com/1Z0-771-pdf-dumps.html
Explanation/Reference:

A theme is a collection of templates and stylesheets that define the layout and appearance of an application. You can create a

custom theme for an application by using the Create Theme Wizard or by copying an existing theme. If you want to use a

custom theme for anotherapplication in the same workspace, you can copy the theme to that application by using the Copy

Theme option in Shared Components. However, if the master theme (the original theme) may still require changes, you need to

subscribe the copied theme to the master theme and refresh the theme whenever there are changes in the master theme. This

solution guarantees that any changes to the master theme are reflected in the copied theme by using a synchronization

process that updates templates and stylesheets based on their subscription status. Verified References: [Creating Themes -

QUESTION: 28

What is the best practice for incorporating parent-child tables in Oracle APEX?

Option A :
Use APEX Collection to store the parent and child data in memory

Option B : Use APEX_ITEM to create dynamic forms on the parent and child tables
Option C : Use APEX Master-Detail form to link the parent and child tables with cascading deletes and
updates
Option D : Use APEX Dynamic Action to create cascading select lists between the parent and child tables

Correct Answer: C

https://www.certsquestions.com/1Z0-771-pdf-dumps.html
Explanation/Reference:

Option 1: This option is incorrect because APEX Collection only stores data in memory and does not provide the ability to

update the source table. This approach may cause data inconsistency if the user does not manually synchronize the data.

Option 2: This option is incorrect because APEX_ITEM only generates HTML markup for the page. This approach requires

significant effort to establish a two-way data connection between APEX and the database. Moreover, it creates a non-generic

solution that requires custom code to handle the dynamic forms. Option 3: This option is correct because APEX Master-Detail

form automatically establishes a two-way data connection between the parent and child tables. It provides cascading deletes

and updates to ensure data consistency, and the Generic column attributes enable Dynamic Actions and validations. Moreover,

the built-in referential integrity ensures that only valid data is stored. Option 4: This option is incorrect because APEX Dynamic

Action requires custom code to establish the data connection between the parent and child tables. This approach creates a

non-generic solution that may not scale well with large datasets. Additionally, it does not provide cascading deletes and

updates that ensure data consistency.

QUESTION: 29

What are the three types of List of Values(LOV) you can create on a page?

Option A : Static LOV

Option B : Cascading LOV
Option C : Dynamic LOV
Option D : Popup LOV

Correct Answer: A,B,C

Explanation/Reference:

A list of values (LOV) is a definition that provides a set of display values and return values for a page item or a report column. A

LOV can be created at the application level as a shared component or at the page level as a local component. There are three

types of LOVs that you can create on a page: Static LOV: A static LOV is based on a fixed list of display values and return

values that you specify when you create the LOV. A static LOV does not change unless you edit it manually. Cascading LOV: A

cascading LOV is based on another parent LOV that determines the values of the child LOV. A cascading LOV changes

dynamically depending on the selection made in the parent LOV. Dynamic LOV: A dynamic LOV is based on a SQL query that

returns display values and return values from the database. A dynamic LOV changes dynamically depending on the data in the

database.

By creating a process on the same page and selecting a trigger type of 'Submit'.

Option C : By creating a process in Shared Components and selecting a trigger type of 'Page Process'
Option D : By creating a process in Shared Components and selecting a trigger type of 'After Submit -
Processes Before Regions'

Correct Answer: B

Explanation/Reference:

Option 1: Incorrect. Adding a process to the region of the page where the form is located will only execute the process when

the region is refreshed and not when the form is submitted. This is not best practice for handling form submission. Option 2:

Correct. The best way to create a process when submitting a form on a page is to create a process on the same page and

select a trigger type of 'Submit'. This will execute the process on form submission and is the recommended method for

handling form submission. Option 3: Incorrect. Creating a process in Shared Components and selecting a trigger type of 'Page

Process' is not the recommended way to handle form submission as it will only execute when the page is loaded, and not on

form submission. Option 4: Incorrect. Creating a process in Shared Components and selecting a trigger type of 'After Submit -

Processes Before Regions' is not the recommended way to handle form submission as it executes before the form is processed,

and is not the best practice for handling form submission.

QUESTION: 43

Which of the following statements accurately describes best practices when creating and managing a
workspace in Oracle APEX Cloud Developer Professional?

Option A : A workspace should be created for each application to ensure easy management and efficient
development
Option B : Workspaces should only be used for testing and development, production environment
shouldn't use workspace
Option C : A single workspace should be created to manage all applications in the organization for better
control and security
Option D : Workspaces should only be created by administrators, developers shouldn't be allowed to
create their own workspaces

Correct Answer: A

Explanation/Reference:

Option 1: This option is the correct answer because creating a workspace for each application allows for easy management,

efficient development, and enables developers to compartmentalize their work and test in isolation. It's best practice to create

a workspace for each application to enable the developers to create, modify, and test an application before promoting it to

production. Option 2: This option is incorrect because workspaces can be used for both testing/development and production

environments. It's not recommended to use workspaces for production environments but it's definitely possible to use them.

Option 3: This option is incorrect because creating a single workspace for all applications can lead to security and control

problems. It's best to compartmentalize the applications for ease of management Option 4: This option is incorrect because

developers are allowed to create their own workspaces. An organization's policies may require them to create a workspace, or

the developer might prefer to create a workspace to facilitate their development process. The policy for creating workspaces

should be established by an administrator and should be consistent with the organization's requirements and security policies.

QUESTION: 44

Which of the following techniques can be used to improve the performance of an Oracle APEX application?

Option A : Caching static data in shared components.

Option B : Increasing the number of database connections.

https://www.certsquestions.com/1Z0-771-pdf-dumps.html
 Option C : Enabling auto-submit behavior for all form items.
Option D : Embedding large amounts of data in session state.

Correct Answer: A

Explanation/Reference:

Option 1: Correct: Caching static data in shared components can improve the performance of an Oracle APEX application. By

storing static data, such as lookup tables or reference data, in the shared components of your application, you can reduce the

need for frequent database queries. This can result in faster page load times and improved overall performance. Option 2:

Incorrect: Increasing the number of database connections does not directly improve the performance of an Oracle APEX

application. The number of database connections should be configured based on the expected workload and the capacity of

your database server. Adjusting this parameter without considering the underlying system resources can actually degrade

performance. Option 3: Incorrect: Enabling auto-submit behavior for all form items can have a negative impact on the

performance of an Oracle APEX application. Auto-submit behavior causes a form item to submit its value to the server

whenever it is changed. This can result in a high volume of server requests and additional processing overhead, which can

degrade performance. Option 4: Incorrect: Embedding large amounts of data in session state can negatively impact the

performance of an Oracle APEX application. Storing large amounts of data in session state can consume significant server

memory and increase the response time for each request. It is recommended to only store necessary session data and offload

larger data to the database or other external storage.

QUESTION: 47

In Oracle APEX Cloud, what is the difference between a classic report and an interactive report?

Option A : A classic report is a read-only view of data while an interactive report allows users to
manipulate data directly in the report
Option B :
A classic report can only display data from one table while an interactive report can display data from
multiple tables

Option C : A classic report can be edited in Page Designer while an interactive report cannot
Option D : A classic report is faster to load than an interactive report

Correct Answer: A

Explanation/Reference:

Option 1: This is correct. A classic report is a simple read-only view of data while an interactive report allows users to

manipulate data directly in the report by adding filters, sorting columns, and editing data inline. This makes interactive reports

https://www.certsquestions.com/1Z0-771-pdf-dumps.html
more powerful and flexible than classic reports. Option 2: This is not correct. Both classic and interactive reports can display

data from multiple tables. The difference between them lies in the degree of user interactivity. Option 3: This is not correct.

Both classic and interactive reports can be edited in Page Designer. However, in the Interactive Report, you can edit the

attributes of the columns and create various report regions and chart types that work with the report Option 4: This is not

correct. Interactive reports generally take longer to load than classic reports because they involve more processing on the

server side. However, the added user interactivity provided by the interactive report typically justifies this extra processing

time.
