GET /v1/memberships/me

Answer

GET /v1/rooms/me

Question 2

When using the NX-API on Cisco NX-OS, which HTTP method is used to send CLI commands in JSON format?

Accepted Answer

POST. NX-API uses POST requests to the /ins endpoint with a JSON body containing the CLI commands and the type (cli_show or cli_conf).

Answer

PUT

Answer

GET

Answer

PATCH

Question 3

In Cisco DNA Center, which API category includes the ability to deploy a configuration template to devices?

Accepted Answer

Change your network. The 'Change your network' category includes template deployment, plug and play, and other configuration changes.

Answer

Run your network

Answer

Know your network

Answer

Platform

Question 4

Which Meraki API response header provides information for paginating through a large result set?

Accepted Answer

Link. Meraki uses the Link header (LinkHeader) with 'next' and 'prev' URLs, or alternatively the startingAfter/endingBefore parameters. The Link header is standard for pagination.

Answer

Content-Range

Answer

X-RateLimit-Remaining

Answer

Retry-After

Question 5

A developer is building an application that interacts with the Webex API to create rooms and send messages. The application needs to receive real-time notifications when a new message is posted in any room. Which TWO actions should the developer take? (Choose two.)

Accepted Answer

Provide a target URL where the webhook sends the notification. Option B is correct because Webex webhooks require the developer to supply a targetUrl — an HTTPS endpoint on their own publicly reachable service — where Webex will POST the notification payload when the subscribed event fires. Option D is correct because real-time notification of a new message is delivered by registering a webhook whose event is 'created' and whose resource is 'messages' (i.e., message.created), which is exactly the trigger Webex uses for newly posted messages. Option A is wrong because polling GET /v1/messages every second is inefficient, rate-limit prone, and not a real-time push mechanism. Option C is wrong because roomId is a filter/query parameter for listing messages, not a mechanism for receiving notifications. Option E is wrong because 'seen' is not a valid message event for this purpose and the payload described does not register a message-created subscription.

Answer

Poll the GET /v1/messages endpoint every second

Answer

Use the 'roomId' parameter to filter messages

Answer

Send a POST request to /v1/webhooks with 'resource: messages' and 'event: seen'

Question 6

A network engineer is using Cisco DNA Center to automate network changes. Which THREE operations are part of the 'Change your network' API category? (Choose three.)

Accepted Answer

Create and assign a site to a device. The 'Change your network' API category in Cisco DNA Center includes operations that actively modify the network state. Creating and assigning a site to a device is a configuration change that associates a physical location with a device, which directly alters the network's logical topology and is part of the site management workflow under this API category.

Answer

Run a command on a device via Command Runner

Answer

Retrieve the list of network devices

Question 7

A developer is working with the Meraki Dashboard API to manage SSIDs. Which TWO statements about pagination are correct? (Choose two.)

Accepted Answer

The 'endingBefore' parameter is used to go to the previous page. Meraki uses the Link header with 'prev' and 'next' URLs for pagination. Additionally, the startingAfter and endingBefore query parameters allow manual pagination.

Answer

Pagination is handled automatically by the client library; no action required

Answer

The 'page' query parameter is used to specify page number

Answer

The Link header contains a 'last' URL for the final page

Question 8

A network engineer wants to retrieve a list of all network devices from Cisco DNA Center using REST API. Which URL and HTTP method should be used?

Accepted Answer

GET /dna/intent/api/v1/network-device. Cisco DNA Center provides the GET /dna/intent/api/v1/network-device endpoint to list all network devices.

Answer

POST /dna/intent/api/v1/network-device

Answer

GET /dna/system/api/v1/auth/token

Answer

GET /dna/intent/api/v1/topology/l2/{vlanID}

Question 9

An administrator is configuring a Cisco Meraki Dashboard API integration. After receiving a 429 HTTP response, what header should be examined to determine when the request can be retried?

Accepted Answer

Retry-After. Meraki's rate limit returns a 429 status with a Retry-After header indicating the number of seconds to wait before retrying.

Answer

X-RateLimit-Reset

Answer

X-Cisco-Meraki-API-Key

Answer

Location

Question 10

A developer wants to create a new room in Cisco Webex using the API. Which HTTP request is appropriate?

Accepted Answer

POST /v1/rooms. Creating a new Webex room is a resource-creation operation, which maps to HTTP POST against the /v1/rooms collection. POST /v1/rooms with a JSON body containing the title creates the room and returns its details. This follows standard REST semantics.

Answer

GET /v1/rooms

Answer

PUT /v1/rooms

Answer

DELETE /v1/rooms

Question 11

An application uses Cisco DNA Center APIs and needs to receive notifications when a new device is added. Which DNA Center API category should be used to set up event-driven notifications?

Accepted Answer

Platform. The Platform API category in Cisco DNA Center provides the necessary endpoints for subscribing to event notifications, including the ability to create webhook subscriptions for events such as new device additions. This category includes the Event Management and Notification APIs that allow applications to receive real-time updates. The other categories focus on network operations, not event-driven integration.

Answer

Change your network

Answer

Know your network

Answer

Run your network

Question 12

A Meraki dashboard API request to list networks returns a paginated response. The engineer notices a Link header in the response. What does this header typically contain?

Accepted Answer

A URL to the next page of results. Meraki uses Link headers for pagination, providing URLs for the next and previous pages.

Answer

The rate limit remaining

Answer

The total number of resources

Answer

An error message

Question 13

An engineer is developing an EEM applet on a Cisco IOS XE device to run a CLI command when a specific syslog message appears. Which event trigger should be used?

Accepted Answer

event syslog pattern. The syslog pattern event trigger allows matching a specific syslog message pattern.

Answer

event interface

Answer

event timer

Answer

event cli match

Question 14

A developer wants to use the Cisco Webex API to send a message to a specific person by email. Which parameter should be used in the POST /v1/messages request?

Accepted Answer

toPersonEmail. To send a message to a person, use the toPersonEmail parameter instead of roomId.

Answer

personId

Answer

recipientEmail

Answer

roomId

Question 15

An application needs to retrieve all network clients from a specific Meraki network. The API response may be paginated. Which query parameters can be used to implement cursor-based pagination with the Meraki Dashboard API?

Accepted Answer

startingAfter and endingBefore. Meraki supports cursor-based pagination using startingAfter and endingBefore parameters.

Answer

offset and limit

Answer

page and perPage

Answer

nextToken and previousToken
