Which two statements are correct about Juniper Mist subscriptions? (Choose two.)
- A. Subscriptions are not associated with a specific device serial number.
- B. Subscriptions are associated with a specific device serial number.
- C. If a device fails and is removed from the network, the subscription will automatically apply to the new device when added.
- D. If a device fails and is removed from the network, you must manually transfer the subscription to the new device before installing.
Answer: A,C
Explanation:
In theJuniper Mist Cloud licensing model, subscriptions represent service entitlements that enable specific features such asWireless Assurance,Wired Assurance,WAN Assurance,Marvis Virtual Network Assistant, andPremium Analytics. These subscriptions are managed at theorganization leveland are not permanently tied to individual hardware units.
According to theJuniper Mist Licensing and Subscription Management Guide, subscriptions are:
"Cloud-based entitlements associated with an organization, not bound to specific device serial numbers.
Devices draw from the subscription pool dynamically."
This design allows flexibility and simplifies device replacement or scaling:
* When a new device (for example, an access point or switch) is added to the organization, the subscription is automatically assignedto it from the available pool.
* If a device isremoved or fails, the subscription is automaticallyreleased and reassignedto a replacement unit-no manual transfer is required.
Therefore:
* Ais correct because subscriptions are not linked to a single device's serial number.
* Dis correct because subscriptions automatically reapply when replacement devices are onboarded.
OptionsBandCare incorrect because Juniper Mist subscriptions are organization-based, not hardware-bound, and require no manual reassignment after device failure or replacement.

- A. A DHCP lease must be obtained by the switch.
- B. The switch's clock must be synchronized with an NTP server.
- C. NETCONF must be configured on the switch.
- D. All user accounts must be configured on the switch.
Answer: A
Explanation:
A DHCP lease must be obtained by the switchbefore the ZTP process proceeds. Juniper documentation clarifies: "Ensure that a DHCP server is reachable. In addition to providing an IP address to the switch, your DHCP server must provide the following information: a default gateway, an NTP server, and a DNS server address..." The initial event in the ZTP workflow is the switch receiving a valid IP address via DHCP. Only after obtaining an address can the switch connect to the Mist cloud and proceed with zero-touch provisioning.
Other requirements, such as user account, NETCONF, or NTP sync, occur later or are handled automatically via cloud policy after onboarding.
