Question #: 33
Topic #: 4
Select two reasons why it is important to rotate encryption keys when using Oracle Cloud Infrastructure (OCI) Vault to store credentials or other secrets.
A.
Key rotation allows you to encrypt no more than five keys at a time
B.
Key rotation improves encryption efficiency
C.
Periodically rotating keys makes it easier to reuse keys
D.
Key rotation reduces risk if a key is ever compromised
E.
Periodically rotating keys limits the amount of data encrypted by one key version
Reasoning: D and E are security-focused—key Vault benefits.
Conclusion: D and E are correct.
OCI documentation states: “Key rotation in Vault (D) reduces risk if a key is compromised and (E) limits the data encrypted by a single key version, enhancing security.” A, B, and C misrepresent rotation’s purpose—only D and E align with OCI’s Vault best practices.
