300-410 Practice Question: Which IPv6 FHS feature uses a 'device tracking'…
Which IPv6 FHS feature uses a 'device tracking' database to maintain reachability information for hosts?
⚠ Common exam trap
Cisco often tests the distinction between features that maintain the database (Device Tracking) versus features that use the database (e.g., DHCPv6 Guard, RA Guard), so the trap here is assuming that any FHS feature that interacts with host information must be the one that maintains the tracking database.
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
✓
Device Tracking
Device Tracking is the correct answer because it is the IPv6 First Hop Security (FHS) feature that maintains a 'device tracking' database to monitor and store reachability information for hosts. This database tracks the IPv6 address, MAC address, and binding state of each host, enabling features like ND Inspection and DHCPv6 Guard to verify host reachability before forwarding 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.
- ✗
RA Guard
Why it's wrong here
RA Guard does not maintain a device tracking database; it filters RAs.
- ✗
DHCPv6 Guard
Why it's wrong here
DHCPv6 Guard filters DHCPv6 messages and does not maintain a device tracking database.
- ✓
Device Tracking
Why this is correct
Correct. Device Tracking maintains a database of IPv6 addresses and their reachability.
- ✗
PACL
Why it's wrong here
PACL (Port ACL) is not a specific IPv6 FHS feature; it is a general ACL applied to a port.

Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
