Oracle Cloud Infrastructure 2019 Developer Associate — Question 66

An instance is launched with a primary VNIC that is created during instance launch.
Which two operations are true when you add secondary VNICs to an existing instance? (Choose two.)

Answer options

• A. You can remove the primary VNIC after the secondary VNIC's attachment is complete.
• B. You can remove the secondary VNIC later if it is not needed.
• C. The primary and secondary VNIC association should be within the same Availability Domain.
• D. It is not possible to connect two VNICs to an instance.

Correct answer: B, C

Explanation

Option B is correct because secondary VNICs can be detached if they are no longer needed. Option C is also correct as both primary and secondary VNICs must be in the same Availability Domain to function properly. Option A is incorrect because the primary VNIC cannot be removed after adding secondary VNICs, and Option D is wrong since it is indeed possible to connect multiple VNICs to an instance.
