Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Security lists and NSGs support rules for IPv6 traffic filtering.
OCI supports IPv6 addressing. You can assign IPv6 CIDR blocks (/56) to your VCN, assign IPv6 subnets (/64) to subnets, and configure security rules and route tables for IPv6 traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Security lists and NSGs support rules for IPv6 traffic filtering.
Why this is correct
Security rules can be configured for IPv6 CIDRs just like IPv4.
- ✓
Subnets within an IPv6-enabled VCN can be assigned /64 IPv6 prefixes.
Why this is correct
Subnets receive /64 IPv6 blocks from the VCN's IPv6 prefix.
- ✗
IPv6 is mandatory for all new VCN creation in OCI.
Why it's wrong here
IPv6 is completely optional; IPv4 is the default.
- ✗
IPv6 addresses in OCI require a NAT Gateway for outbound internet access.
Why it's wrong here
IPv6 uses direct routable GUA addresses; NAT is not required for IPv6 internet communication.
- ✓
You can assign an IPv6 GUA (Globally Unique Address) prefix of /56 to your VCN.
Why this is correct
VCNs support assigning an Oracle-provided /56 IPv6 prefix.
