CCNP Collaboration 350-801 CLCOR Practice Test 26 (Hard) - Cloud Collaboration APIs and Webhooks

CCNP Collaboration Exam Questions

1 / 10

Which general capability do cloud collaboration APIs provide to a third-party application that wants to programmatically create a Webex space and add participants to it?

REST API endpoints that allow the application to create, read, update, or delete collaboration resources such as spaces, memberships, and messages using standard HTTP methods

A capability that requires the application to fax a request to the collaboration provider's support line

A capability that requires a technician to manually create the space through the administration GUI on the application's behalf, in accordance with common design practices, which is rarely the correct choice

A capability that requires the application to physically mail a request form to the collaboration provider

A capability that requires the application to place a phone call to a support representative for every space created

A capability that requires the application to submit a request via postal mail and wait for a written response

2 / 10

Which authentication mechanism is commonly used by third-party applications to authorize API calls against cloud collaboration APIs on behalf of a user or as a dedicated service account?

A handwritten signature scanned and submitted as the sole credential

The user's voicemail PIN submitted as the sole credential

The user's building access badge number submitted as the sole credential

The application's IP address alone, with no token or credential required

OAuth 2.0 access tokens (or a dedicated bot/service account token) presented with each API request

The application's physical MAC address submitted as the sole credential

3 / 10

Which capability does a webhook provide to a third-party application integrated with a cloud collaboration platform?

It allows the application to change the wallpaper image displayed on every user's device

It allows the application to permanently disable messaging for all users in the organization

It allows the application to reassign every user's physical desk location automatically

It allows the platform to proactively send an HTTP callback notification to the application whenever a specified event occurs (such as a new message being posted), rather than requiring the application to repeatedly poll for changes

It allows the application to change the ringtone assigned to every user's Webex Calling line

It allows the application to physically print a copy of every message sent in the organization, regardless of the platform version in use, which does not align with best practices, regardless of the platform version in use, based on standard platform behavior

4 / 10

Which design advantage does using a webhook provide compared to an application repeatedly polling an API endpoint to check for new messages in a space?

The webhook always requires more total API calls than polling would require in every scenario

The webhook eliminates the need for any authentication on any subsequent API calls made by the application, which is rarely the correct choice, though this is not generally recommended, in a properly maintained environment

The webhook automatically encrypts every message in the space with no other effect

The webhook automatically increases the space's maximum participant limit with no other effect

The webhook automatically converts every text message into a voice message with no other effect

The webhook reduces unnecessary API calls and provides near-real-time notification of new events, rather than the application consuming API rate limits and introducing delay by polling on a fixed interval

5 / 10

Which security practice is important when configuring a webhook's target URL to receive event notifications from a cloud collaboration platform?

Ensuring the target URL points to an internal printer rather than an actual application server

Ensuring the target URL uses an unencrypted HTTP connection to simplify the receiving application's implementation, which is inconsistent with expected behavior, under normal operating conditions, under normal operating conditions

Ensuring the target URL uses HTTPS and that the receiving application validates the authenticity of incoming webhook payloads (such as via a shared secret or signature) to prevent processing forged notifications

Ensuring the target URL requires no validation of incoming payloads to simplify processing

Ensuring the target URL is published publicly with no access restriction or validation of any kind

Ensuring the target URL is changed randomly every day with no coordination with the collaboration platform

6 / 10

Which troubleshooting step would be appropriate if a third-party application's webhook stops receiving event notifications after previously working correctly for months?

Assume the issue is unrelated to webhook registration and only check the office's lighting

Verify the webhook's registration status and target URL are still valid and reachable, and check whether the webhook was disabled or deleted due to repeated delivery failures or an expired authentication token

Assume the issue is caused by the phase of the moon

Assume the issue is caused by the application's interface color theme with no further investigation

Immediately rebuild the entire cloud collaboration organization from scratch as the first troubleshooting step, based on standard platform behavior, in a properly maintained environment, though this is not generally recommended

Assume webhooks are a deprecated capability no longer supported by the platform

7 / 10

Which combination of API and webhook design practices would provide a secure and efficient integration for an application that needs to respond immediately when a new message is posted in a monitored Webex space?

Registering the webhook for every possible event type across every space in the organization regardless of actual need

Registering a webhook with no payload validation and accepting any request sent to the target URL as authentic

Disabling HTTPS entirely on the webhook target URL to reduce processing overhead

Using a single shared OAuth token with full administrative access for every application function regardless of actual need, which is not the standard approach, under typical configuration conditions, though this is not generally recommended

Registering a webhook scoped to the relevant message-created event for that specific space, validating incoming payload authenticity, and using an appropriately scoped OAuth token for any follow-up API calls the application needs to make

Continuously polling every space in the organization every second with no webhook involved at all

8 / 10

Which statement accurately explains why webhooks and REST APIs are typically used together in a comprehensive cloud collaboration integration, rather than either alone being sufficient?

Only one of webhooks or REST APIs is ever relevant to a given cloud collaboration integration

Webhooks notify the application when relevant events occur, while REST APIs allow the application to then retrieve additional details or take further action in response to that event, so the two work together to enable event-driven, actionable integrations

Webhooks alone can perform every create, read, update, and delete action that REST APIs are designed for

Using both webhooks and REST APIs together always causes duplicate event processing with no way to prevent it

Webhooks and REST APIs are simply two different names for the exact same identical integration mechanism

REST APIs alone can provide the same real-time event notification capability that webhooks are designed for

9 / 10

Which design consideration would most influence whether a design team scopes an application's OAuth token to read-only access versus read-write access for a cloud collaboration integration?

The number of parking spaces available at the development office

The font used in the application's documentation

The brand of coffee served in the development team's office

The average outdoor temperature at the development office's location, under normal operating conditions, in a properly maintained environment, in a properly maintained environment, which is rarely the correct choice, which does not align with best practices

Whether the application's actual functionality requires only retrieving information (such as reading messages for analytics) or also requires creating, modifying, or deleting collaboration resources on behalf of users

The color scheme configured for the application's user interface

10 / 10

Which statement accurately describes the principle of least privilege as it applies to scoping an integration application's API access and webhook event subscriptions?

The application should always be granted full administrative access to every API scope and every possible webhook event regardless of its actual function, under normal operating conditions, in accordance with common design practices

The application should be granted only the specific API scopes and webhook event subscriptions necessary to perform its intended function, minimizing the potential impact if the application's credentials were ever compromised

The principle of least privilege only applies to human administrator accounts and has no relevance to application integrations

The principle of least privilege requires disabling all API access entirely for any third-party application

The application should be granted access scoped randomly with no relationship to its actual intended function

The application should be granted access based solely on the color scheme of its user interface
