350-601 Security Practice Question
An engineer needs to secure the management plane on a Cisco Nexus 9000 switch. Which feature should be configured to restrict access to the switch's management interface based on source IP?
⚠ Common exam trap
Cisco often tests the distinction between data-plane security features (DHCP snooping, port security) and control-plane security mechanisms (CoPP), leading candidates to mistakenly choose a Layer 2 feature for a management plane access restriction question.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a management CoPP policy to rate-limit and permit only specific source IPs.
A management Control Plane Policing (CoPP) policy on a Cisco Nexus 9000 switch allows the engineer to explicitly permit or deny traffic destined to the management interface based on source IP addresses. CoPP applies QoS policies to control plane traffic, effectively restricting management plane access by rate-limiting or dropping packets from unauthorized sources before they reach the CPU.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable DHCP snooping on the management VLAN.
Why it's wrong here
DHCP snooping is for DHCP spoofing.
- ✗
Enable port security on the management interface.
Why it's wrong here
Port security is for end-user ports.
- ✗
Configure AAA to require two-factor authentication.
Why it's wrong here
AAA provides authentication but not source IP filtering.
- ✓
Configure a management CoPP policy to rate-limit and permit only specific source IPs.
Why this is correct
CoPP can filter management traffic to the switch.
