A company is considering implementing IBM Cloud for its resiliency solution. They want to ensure
maximum protection against natural disasters and are looking for a redundant infrastructure with
multiple layers of resiliency.
What is the most predominant aspect of the overall resiliency solution in IBM Cloud?
C
Explanation:
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) and Network 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.

How does a monitoring agent properly authenticate with the IBM Cloud Monitoring service it is
sending metrics to?
C
Explanation:
In IBM Cloud, a monitoring agent properly authenticates with the IBM Cloud Monitoring service by
using a service 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.
