A company is integrating a cloud-based inventory system with an on-premises ERP using REST APIs. The integration will transmit sensitive pricing data. Which security measure is essential to protect the data in transit?

Relying on the cloud provider's network security alone

Using HTTPS with TLS 1.2 or higher for all API calls

Storing API keys in plain text in the integration configuration

Using HTTP with basic authentication

A company's integration between a cloud CRM and an on-premises ERP started failing after a recent update to the CRM's API. The error logs show HTTP 401 Unauthorized responses. The integration uses OAuth 2.0 with client credentials. What is the most likely cause and the first step to resolve it?

The client secret was rotated, and the integration is using an outdated secret; update the secret in the integration configuration

The integration's IP address is blocked by the CRM's firewall; whitelist the IP

The API endpoint URL changed; update the endpoint in the integration code

The ERP database is down; restart the database

What is the purpose of encrypting data in transit during system integration?

To speed up the data transfer process

To reduce the size of the data being transferred

To ensure data is stored securely on the receiving system

To protect data from unauthorized access while it is being transmitted

What is the primary role of an API in cloud service integration?

To define a set of rules and protocols for software components to communicate

To store data in a structured format for cloud applications

To secure network connections between cloud data centers

To provide a user interface for managing cloud resources

A retail company syncs product inventory between a cloud-based POS system and an on-premises warehouse management system (WMS). They are experiencing data inconsistencies, with some products showing different stock levels in each system. They need to implement a synchronization strategy that ensures eventual consistency and minimizes data loss. Which approach should they choose?

Make the WMS the master and overwrite the POS data with WMS data every hour

Use a shared database for both systems to read and write

Sync only when a sale occurs, pushing POS data to the WMS

Implement a bidirectional sync with conflict resolution based on timestamps, using a middleware queue
