NEW QUESTION # 61
Which three are true aboutprivileges and roles?

A. A user has all object privileges for every object in their schema by default.
B. System prilgese always set prilge for an entire database.
C. PUBIIC can be revoked from a user.
D. PUBLIC acts as a default role granted to every user in a database.
E. All roles are owned by the sYs schema.
F. A role can contain a combination of several privileges and roles.
G. A role is owned by the user who created it.

Answer: A,D,F

Explanation:
In Oracle Database 12c, the following are true about privileges and roles:
* Option B: PUBLIC acts as a default role granted to every user in a database.
* The PUBLIC role is a special role that is automatically granted to all users. It can be used to provide privileges to every user.
* Option C: A user has all object privileges for every object in their schema by default.
* By default, a user has all privileges on the objects they own, i.e., the objects in their schema.
* Option D: A role can contain a combination of several privileges and roles.
* Roles are designed to group together privileges and other roles, making it easier to manage and assign security settings to users.
Options A, E, F, and G are incorrect because:
* Option A: System privileges can be set for specific schemas or objects, not always for the entire database.
* Option E: Roles are not "owned" by users in the traditional sense of ownership; they are managed by the database and can be granted to any user.
* Option F: Not all roles are owned by the SYS schema; roles are a database security concept and do not have an "owner".
* Option G: The PUBLIC role is not something that can be revoked from a user; it is a default role that exists for all users.

NEW QUESTION # 70
Which three statements are true about indexes and their administration in an Oracle database?

A. An INVISIBLE index is not maintained when Data Manipulation Language (DML) is performed on its underlying table.
B. A descending index is a type of function-based index
C. A UNIQUE and non-unique index can be created on the same table column
D. An index can be created as part of a CREATE TABLE statement.
E. If a query filters on an indexed column then it will always be used during execution of the query
F. A DROP INDEX statement always prevents updates to the table during the drop operation

Answer: B,C,D

Explanation:
A . This statement is incorrect. An INVISIBLE index is maintained during DML operations just like a VISIBLE index. The difference is that an INVISIBLE index is not used by the optimizer unless explicitly hinted. B. This statement is correct. When creating a table, you can define indexes on one or more columns as part of the table definition. C. This statement is incorrect. While a DROP INDEX statement will drop the index, it does not always prevent updates to the table. If the index is marked as unusable or is an invisible index, for example, updates can still be performed. D. This statement is correct. It is possible to have both a UNIQUE index and a non-unique index on the same column. The UNIQUE index enforces the uniqueness of column values, while the non-unique index does not. E. This statement is correct to some extent. Descending indexes are not function-based indexes per se, but they are indexes on which the data is sorted in descending order, as opposed to the default ascending order. However, descending indexes are conceptually related to function-based indexes because they alter the way the indexed data is stored. F. This statement is incorrect. The use of an index in query execution depends on the optimizer's decision, which is based on statistics and the cost associated with using the index. There are situations where the optimizer may choose a full table scan even if there is an index on the filter column.
Reference can be found in the Oracle Database Concepts Guide and the SQL Language Reference documentation, which detail the behavior of indexes and how they are managed within the Oracle database.

Answer: C

Explanation:
To calculate the length of employment, you would compare the current date to the HIRE_DATE and calculate the difference in years.
A . This is the correct answer. The expression calculates the number of days between the current date (SYSDATE) and the HIRE_DATE, then divides by 365 to convert it to years, and checks if it is greater than 5.
B . SYSTIMESTAMP includes a time component including fractional seconds and time zone information, making this comparison incorrect.
C . There are typos in this option (CUARENT_DATE should be CURRENT_DATE and hire_data should be hire_date). Even with the correct function and column names, CURRENT_DATE returns the current date in the session time zone, not in years.
D . There are typos in this option (SYSNAYW should be SYSDATE). Additionally, dividing by 12 incorrectly assumes that a month is equivalent to a year.
E . This is a repetition of option D with the same issues.
F . There are typos in this option (CUNACV_DATE should be CURRENT_DATE and hire_data should be hire_date). Additionally, dividing by 12 incorrectly assumes that a month is equivalent to a year.
