Which three are true about an application container?

Question

Options

• AIt always contains multiple applications.
• BTwo or more application PDBs in the same application container can share access to tables.
• CIt can have new application PDBs created by copying PDB$SEED.
• DTwo or more application PDBs in the same application container can be given exclusive access to
• EIt always has a new application PDBs created by copying PDB$SEED.
• FIt always contains a single application.

• A
  6% (2)
• B
  82% (28)
• E
  9% (3)
• F
  3% (1)

Explanation

B is correct because application containers support data-linked and metadata-linked common objects - tables defined at the application root can be shared across all application PDBs within the same container, which is a core feature of this architecture.

C is correct because creating new application PDBs by copying PDB$SEED is a valid method - the word "can" is key here. Application PDBs can also be created from an application seed, making this a true but non-exclusive option.

D is correct because application PDBs can also have local, exclusively-owned objects (not all objects need to be shared). A PDB can hold tables inaccessible to sibling PDBs in the same container.

A is wrong because an application container can have only one application PDB, or even just an application root with no PDBs yet - "always multiple" is too absolute.

E is wrong for the same reason C is right - swapping "can" for "always" breaks it. Application PDBs can also be seeded from an application seed, not exclusively from PDB$SEED.

F is wrong because an application container is not strictly limited to housing a single application definition; the statement is misleadingly absolute and conflates the container structure with application count.

Memory tip: Focus on the word "can" vs "always." Options with "always" (A, E, F) are traps - application containers are flexible, not rigidly constrained to one creation method or one application count.
