Pass the IBM IBM Cloud: Cloud Solutions C1000-172 Questions and answers with CertsForce

The most predominant aspect of an overall resiliency solution in IBM Cloud is "Addressing physical events." This refers to the ability to maintain service continuity and recover quickly from physical disruptions such as natural disasters (earthquakes, floods, fires, etc.). IBM Cloud provides multiple layers of resiliency, including geographic redundancy, data replication, backup, and disaster recovery services to ensure high availability and business continuity in the event of such physical events.

Physical Resiliency:IBM Cloud's strategy includes using multiple regions and availability zones to create a resilient infrastructure that can withstand physical events. By deploying applications across multiple zones and regions, the impact of a physical event is minimized.

Comprehensive Approach:Addressing physical events is part of a broader resiliency framework that also considers other types of failures (network, storage, etc.). Still, dealing with physical events like natural disasters is the most critical aspect of ensuring maximum protection and continuous operation.

Comparison with Other Options:

Storage requirements (A)andNetwork requirements (B)are important for overall performance but are not the primary aspect of resiliency.

Capture historical events (D)is related to logging and monitoring, not directly linked to resiliency from physical events.

To ensure that sensitive monitoring data does not travel across the public internet, a client canconfigure the monitoring instance and monitoring agents to only use private endpoints.

IBM Cloud Monitoring Private Endpoints: IBM Cloud Monitoring with Sysdig allows users to configure their monitoring instance and agents to communicate only over private endpoints. This configuration ensures that monitoring data remains within IBM’s private network, thus avoiding exposure to the public internet.

Private Endpoints for Data Security: Using private endpoints is crucial for clients who require that their sensitive data, such as monitoring metrics, never leave the secure IBM Cloud network, enhancing overall security.

References from IBM Cloud Professional Architect Materials:

IBM Cloud documentation on Configuring Private Endpoints for IBM Cloud Monitoring confirms that monitoring data can be restricted to private endpoints to avoid exposure to the public internet.

Other options are incorrect:

A. Encrypt all monitoring data with a user-controlled key from Key Protect or Hyper Protect Crypto Servicesdoes not prevent data from traveling across the public internet.

C. Ensure that all resources being monitored are in the same region as the IBM Cloud monitoring instanceis a good practice for performance but does not specifically ensure that data doesn’t travel over the public internet.

D. Use only private endpoints to store monitoring data in IBM Cloud Object Storageis related to storage, not monitoring data transmission.

Therefore, the correct answer isB. Configure the monitoring instance and monitoring agents to only use private endpoints.

To achieve a high availability strategy with a target of four nines (99.99%) for an IBM Kubernetes Services cluster, you need to deploy multiple worker nodes across at least three availability zones within a single region. This configuration ensures that even if one or two zones experience failures, the cluster remains operational, thus meeting the 99.99% uptime objective.

High Availability in IBM Cloud Kubernetes Service:Deploying worker nodes across multiple availability zones provides redundancy and fault tolerance. By having at least three zones, the Kubernetes cluster can tolerate failures in up to two zones while still maintaining functionality.

Comparison of Options:

A (Single worker node in a single zone):Insufficient for high availability as any zone failure would result in downtime.

B (Multiple nodes in a single zone):Provides redundancy but still vulnerable to zone-wide outages, not meeting 99.99% uptime.

C (Multiple nodes in at least three zones across multiple regions):While this offers high availability, it exceeds the requirements stated for achieving 99.99% within a single region.

In IBM Cloud, amonitoring agentproperly authenticates with the IBM Cloud Monitoring service by using aservice instance authorization. This approach allows secure interaction between the monitoring agent and the monitoring service by using identity and access management (IAM) policies and authorizations associated with a service instance.

Service instance authorizations grant specific permissions to services, enabling them to authenticate and interact with other services or resources securely. For IBM Cloud Monitoring, the agent uses the service instance authorization to send metrics to the monitoring service, ensuring that the communication is authenticated and authorized without relying on hard-coded credentials or API keys tied to individual users.

The service instance authorization method is recommended because it is aligned with best practices for securing services in cloud environments, offering a centralized and controlled way to manage permissions.
