NEW QUESTION # 36
Which search type in Search Configurations provides linguistic and fuzzy search capabilities?
- A. Standard
- B. List
- C. Oracle Text
Answer: C
Explanation:
Explanation
Search Configurations is a feature that allows developers to define how end users can search for data in an application. There are three types of search configurations: Standard, List, and Oracle Text. Oracle Text is a search type that provides linguistic and fuzzy search capabilities by using an Oracle Text index on a table column or view column. Linguistic search enables end users to search for data based on language-specific rules and preferences, such as stemming, stopwords, synonyms, etc. Fuzzy search enables end users to search for data based on approximate matches that account for spelling errors, typos, OCR errors, etc. Verified References: [Managing Search Configurations - Oracle Help Center], [Oracle Text User's Guide]
NEW QUESTION # 37
There is a validation of type Item is numeric on the P1_SALARY item. When the page is submitted, this or message is displayed both in the notification and below the item: What will cause the validation error to appear only in the Notification area?
- A. Setting the value Required to Yes on P1_SALARY
- B. Setting Display Location to Inline in Notification
- C. Removing P1_SALARY from the validation Associated Item
Answer: C
Explanation:
Explanation
A validation is a rule that checks the data entered by end users before processing it. A validation of type Item is numeric checks if a page item value is a valid number. When the page is submitted, if the validation fails, an error message is displayed both in the notification area (atthe top of the page) and below the item (next to the item label). To cause the validation error to appear only in the notification area, you need to remove P1_SALARY from the validation Associated Item attribute. The Associated Item attribute specifies which page item is associated with the validation and where to display the error message if the validation fails.
Setting the value Required to Yes on P1_SALARY or setting Display Location to Inline in Notification will not affect the validation error display. Verified References: [Creating Validations - Oracle Help Center],

NEW QUESTION # 38
Which three of the following statements are TRUE about Data Synchronization?
- A. You must trigger Data Synchronization manually
- B. Helps in Providing efficient reporting on large data sets coming from a REST service
- C. APEX can create the local table based on the visible columns in the REST Data Source Data Profile.
- D. Data Synchronization enables developers to automatically sync the contents of a local table with the data from a REST service.
Answer: B,C,D
Explanation:
Explanation
Data Synchronization enables developers to automatically sync the contents of a local table with the data from a REST service. APEX invokes the REST service defined in the REST Data Source, downloads all data and synchronizes it to a local table6. Data Synchronization has several benefits, such as:
APEX can create the local table based on the visible columns in the REST Data Source Data Profile. Since the table is physically available in the database schema, developers can add indexes, change physical properties, or even add more columns6.
Data Synchronization helps in providing efficient reporting on large data sets coming from a REST service. Some REST services can return large amounts of result data that include pagination. If a reporting requirement needs larger data sets, this would lead to multiple HTTP requests and poorer response times. Also, no indexes or other database features can be used to speed up reporting queries. In this case, synchronizing the remote data to a local table and having the reports working on local tables can improve performance and user experience6.
Data Synchronization can also collect data from REST services for consumption by PL/SQL packages or other logic. If data from the REST service is replicated to local tables, developers will be able to perform all sorts of processing and also generate different types of reports6.
You do not have to trigger Data Synchronization manually, as you can also schedule it to run periodically using a DBMS_SCHEDULER expression6.
NEW QUESTION # 39
Which authentication scheme type supports authentication with social networks and enterprise identity providers that support OpenID Connect or OAuth2 standards?
- A. HTTP Header Variable
- B. Open Door Credentials
- C. SAML Sign-In
- D. Social Sign-In
Answer: D
Explanation:
Explanation
An authentication scheme is a rule that determines if a user is authorized to access a specific component or feature of an application, such as a page, region, button, item, etc. An authentication scheme type defines how users are authenticated when they access an application. The authentication scheme type that supports authentication with social networks and enterprise identity providers that support OpenID Connect or OAuth2 standards is Social Sign-In. Social Sign-In supports authentication with Google, Facebook, and other social networks that support these standards. The other authentication scheme types do not support authentication with social networks or enterprise identity providers. They are:
HTTP Header Variable: Authenticate users externally by storing the username in a HTTP Header variable set by the web server.
SAML Sign-In: Delegates authentication to the Security Assertion Markup Language (SAML) Sign In authentication scheme.
Open Door Credentials: Enable anyone to access your application using a built-in login page that captures a user name. Verified References: [Understanding Preconfigured Authentication Schemes - Oracle Help Center], [Social Sign-In - Oracle Help Center]
