A developer is implementing a webhook receiver and wants to verify the HMAC signature. The developer has the secret token and the raw request body. What should the developer do to verify the signature?

Compute SHA256 of the secret token and the body concatenated, then compare to the header.

Compare the 'X-Mist-Signature' header directly to the secret token.

Decode the 'X-Mist-Signature' header using base64 and compare it to the secret token.

Compute HMAC-SHA256 with the secret token as the key and the raw body as the message, then compare the hex digest to the 'X-Mist-Signature' header.

A company's webhook endpoint experienced a prolonged outage, and the team later discovered that many events were not delivered. They want to recover the missed events. What should they do?

Enable the 'Store and Forward' option in the webhook settings.

Contact Juniper support to request a replay of the missed webhooks.

Reconfigure the webhook with a longer retry interval to ensure delivery.

Use the Mist API to query historical events for the period of the outage.

What is the primary purpose of webhooks in Juniper Mist?

To store historical event data for long-term analytics within the Mist cloud

To authenticate users accessing the Mist portal

To provide real-time event notifications to external systems without continuous polling

To allow external systems to poll Mist for event data on a scheduled basis

How does Mist help ensure that a webhook request received by an external system is authentic?

By requiring the external system to send a username and password with each request

By using a static IP address that is pre-approved by the receiver

By using a secret token to generate an HMAC signature that is included in the request

By encrypting the payload with the receiver's public key
