Oracle Exam 1Z0-083 Topic 8 Question 105 Discussion

Actual exam question for Oracle's 1Z0-083 exam

Question #: 105
Topic #: 8

Choose the best answer. Examine this configuration: 1. CDB1 is a container database. 2. DEFAULT_SHARING is METADAT

A3. APP_ROOT is an application root contained in CDB1. 4. APP_PDB1 is an application PDB contained in APP_ROOT. 5. COMPANYAPP is an application contained in APP_ROOT. 6. EMP is a common table created in APP_ROOT and all its application PDBs, created when version 1.0 of COMPANYAPP was installed. You execute these commands: $ sqlplus sys/ orac1e@localhost:1521/cdb1 as sysdba SQL> ALTER SYSTEM SET DEFAULT_SHARING=DATA; System altered. SQL> ALTER SESSION SET CONTAINER=app_root; Session altered. SQL> ALTER PLUGGABLE DATABASE APPLICATION companyapp BEGIN UPGRADE '1.0' TO '2.0'; pluggable database altered. SQL> ALTER TABLE emp ADD (sal NUMBER NOT NULL) ; Table altered. SQL> ALTER PLUGGABLE DATABASE APPLICATION companyapp END UPGRADE TO '2.0'; Pluggable database altered. SQL> ALTER SESSION SET CONTAINER=app_pdb1; Session altered. SQL> DESC emp; Name Null? Type --------------------------------------------------------------ENO NUMBER ENAME VARCHAR2 (20) SQL> SELECT * FROM emp; ENO ENAME ---------------------------------100 Alan 200 Ben SQL> ALTER PLUGGABLE DATABASE APPLICATION companyapp SYNC; What will be the outcome and why?

ASAL will be added to APP_PDB1.EMP, with 0 in columns of existing rows.

BSAL will be added to APP_PDB1.EMP, with NULLs in columns of existing rows.

CIt will return an error because the SYNC operation is not allowed when constraints are added to common objects.

DIt will return an error because EMP is not empty in APP_ROOT.

EIt will return an error because EMP.SAL is empty in APP_ROOT.

Hold on, why is the password 'orac1e' instead of 'oracle'? That's the real mystery here! Anyway, I think the answer is B, since that seems to be the most logical outcome based on the information provided.

Yes, it's common practice to use variations in passwords for security purposes.

I agree, it's probably a security measure to prevent easy access.

This question is a real brain-teaser! I'm going to go with option C, since the SYNC operation might not be allowed when you're adding a constraint to a common object. But I could be wrong, so I'm not too confident in my answer.

Yeah, option C does seem like the most logical answer. Constraints and synchronization can be tricky to handle.

I agree, option C seems like the safest choice. Constraints can definitely impact the SYNC operation.

I think option C is correct too. Adding constraints to common objects during a SYNC operation could cause an error.

I'm not sure about this one, but option C seems to make sense. Constraints can complicate things during synchronization.

Hmm, I'm not sure about this one. The question mentions that EMP is a common table, so I'm wondering if that might affect the outcome. I'll have to think about this a bit more.

I don't think so, the SYNC operation should still work even if constraints are added to common objects.

But what about the constraints on common objects? Could that affect the outcome?

I agree, because EMP is a common table, it makes sense that existing rows would have NULL values for the new column.

I think the answer is B) SAL will be added to APP_PDB1.EMP, with NULLs in columns of existing rows.

I think the answer is B. The ALTER TABLE command will add the SAL column to the EMP table in APP_PDB1, but since the table already has data, the new column will have NULL values for the existing rows.

Yes, because the existing rows in the EMP table will have NULL values for the new SAL column.
