1Z0-1072-26 Networking Practice Question
When designing network security in OCI, you can use Security Lists and Network Security Groups (NSGs). Which TWO statements accurately compare or contrast them?
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 apply to all VNICs in a given subnet, while NSGs apply to a specifically selected set of VNICs.
Security Lists apply to all VNICs in a subnet, whereas NSGs are applied to a specific set of VNICs chosen by you. Both support stateful and stateless rules.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
You cannot use Security Lists and Network Security Groups together for the same VNIC.
Why it's wrong here
A VNIC can be associated with an NSG while its subnet has a Security List attached; rules are additive.
- ✓
Security Lists apply to all VNICs in a given subnet, while NSGs apply to a specifically selected set of VNICs.
Why this is correct
Security Lists are subnet-level constructs, while NSGs are VNIC-level constructs.
- ✓
Network Security Groups allow you to reference other NSGs as sources or destinations in rules.
Why this is correct
NSGs support security rules based on other NSGs, allowing tier-based security grouping (e.g., web tier to db tier).
- ✗
Security Lists can reference other Security Lists by OCID across different VCNs.
Why it's wrong here
Security Lists cannot reference other Security Lists across VCNs.
- ✗
Network Security Groups can only contain stateless rules, whereas Security Lists only contain stateful rules.
Why it's wrong here
Both Security Lists and NSGs support both stateful and stateless rules.
