Which data type is used to define policy in Access Assurance?
- A. TCP port numbers
- B. ASN
- C. User identity and role
- D. VLAN priority bits
Answer: C
Explanation:
Policies in Access Assurance are defined based on user identity and role, allowing dynamic segmentation.

NEW QUESTION # 47
Which Mist solution provides port-level insights for connected wired clients?
- A. Secure Edge
- B. Wired Assurance
- C. Port Authentication Manager
- D. Access Assurance
Answer: B
Explanation:
Wired Assurance delivers real-time port-level analytics for wired clients, allowing visibility into traffic, errors, and power usage. It is not involved in access control or security.
NEW QUESTION # 48
What happens if Access Assurance fails to authenticate a client?
- A. Guest fallback policy can be applied
- B. Client is given full access by default
- C. Client is always disconnected
- D. Static IP is assigned
Answer: A
Explanation:
If Access Assurance fails to authenticate a client, it can apply a fallback policy (e.g., limited guest access) based on predefined rules. This ensures continuity with restricted access.
NEW QUESTION # 49
In SD-WAN, which component is responsible for establishing secure tunnels across WAN links?
- A. Apstra Agent
- B. WAN Edge device
- C. Top-of-rack switch
