Which feature optimizes the work of load balancers on IBM Cloud?
B
Explanation:
Traffic Steering is a feature in IBM Cloud that optimizes the work of load balancers by directing traffic
to the most appropriate resources based on predefined criteria, such as geographic location,
resource availability, or other custom rules. This feature is crucial for optimizing application
performance, reducing latency, and ensuring high availability across different regions and data
centers.
IBM Cloud Load Balancer Overview: The IBM Cloud Load Balancer offers several advanced
capabilities, including Traffic Steering, which enables intelligent routing of client requests. Traffic
Steering can be configured to direct traffic to different backend servers or pools based on various
policies like weighted round-robin, geographic proximity, or failover conditions. This optimizes the
distribution of workloads and enhances the reliability and responsiveness of applications deployed
on the IBM Cloud.
Importance of Traffic Steering: Traffic Steering is particularly beneficial in scenarios involving multi-
region deployments. It ensures that user requests are served by the closest or most responsive data
center, thereby minimizing response times and improving the end-user experience. It also enables
flexible routing based on business logic or dynamic conditions, such as sudden surges in traffic or
failures in specific regions.
Global Load Balancer Role: While the Global Load Balancer (Option D) is used for distributing traffic
across multiple regions, Traffic Steering is a specific feature within the load balancing suite that
controls how traffic is managed. Traffic Steering complements the Global Load Balancer by providing
fine-grained control over traffic distribution strategies, enabling more efficient utilization of
resources.

Which supported use case is for IBM Cloud for VMware virtualized data center extension?
C
Explanation:
The use case for "Migration to the cloud" is most relevant when considering IBM Cloud for VMware
solutions, particularly in the context of virtualized data center extension. Here’s why:
Migration to the Cloud: IBM Cloud for VMware is designed to help organizations extend their on-
premises VMware environments into the IBM Cloud. This is achieved through hybrid cloud
architectures that leverage VMware's technology stack in a cloud environment. Migrating existing
workloads to the cloud without needing to refactor applications is one of the primary use cases for
IBM Cloud for VMware. This is particularly beneficial for businesses looking to transition to the cloud
while maintaining compatibility with their existing VMware tools and processes.
Supported Use Case Explanation: When extending a VMware-based data center to IBM Cloud, the
solution allows for a seamless "lift-and-shift" migration. Organizations can move their virtual
machines (VMs) and applications to the IBM Cloud without changing their underlying infrastructure.
This use case supports continuity, speed, and minimal disruption, which is why "Migration to the
cloud" is the correct answer.
Reference from IBM Cloud Professional Architect Materials:
According to IBM's documentation on IBM Cloud for VMware Solutions, one of the primary use cases
is the ability to extend data center capabilities by migrating VMware workloads to the IBM Cloud.
This extends existing investments in VMware technology while optimizing infrastructure by taking
advantage of IBM Cloud's global data centers and enterprise-grade security and scalability.
IBM Cloud for VMware is positioned as a solution to help businesses modernize their IT
infrastructure by moving to the cloud while avoiding the complexity of refactoring their existing
workloads and applications, aligning directly with the concept of "Migration to the cloud."
In contrast, the other options:
A . Manage security detection and response: This use case pertains more to IBM's security solutions
rather than specific to VMware cloud migration.
B . Modernize security with an open multicloud platform: This is a broader concept that is not
directly tied to VMware environments and their extension or migration.
D . Accelerate regulatory compliance: While this can be an outcome of using IBM Cloud, it is not a
specific use case for extending a VMware virtualized data center to the cloud.
Why does IBM Cloud Analytics Engine decouple compute and storage?
C
Explanation:
IBM Cloud Analytics Engine decouples compute and storage to provide independent scaling and cost
management capabilities. This approach allows organizations to scale compute resources (such as
CPU and memory) separately from storage resources, optimizing both performance and cost.
Independent Scaling: Decoupling compute and storage means that users can scale the computational
power (e.g., number of nodes, processing capabilities) independently of the storage capacity (e.g.,
data stored in IBM Cloud Object Storage). This is particularly useful in data analytics workloads where
the compute requirements may vary significantly over time, but the storage requirements remain
relatively constant.
Cost Control: By allowing compute and storage to be managed separately, users have greater
flexibility to control costs. For example, users can increase compute power temporarily to handle a
peak workload without the need to increase storage costs. Conversely, they can store large datasets
without paying for unused compute capacity. This decoupling leads to a more cost-effective and
efficient use of cloud resources.
Advantages in Cloud Environments: Decoupling compute and storage aligns with the best practices in
modern cloud environments, where elasticity, scalability, and cost efficiency are paramount. It allows
organizations to adapt quickly to changing business needs and workload demands, reducing
overhead and improving resource utilization.

Which statement best describes an IBM Cloud multizone region (MZR)?
D
Explanation:
An IBM Cloud multizone region (MZR) is designed to enhance the availability, reliability, and
resilience of cloud services. It consists of three or more separate, geographically dispersed zones
within a single region, which are interconnected through high-speed and low-latency networks.
Multiple Zones for High Availability: In a multizone region, each zone represents a separate data
center or availability zone with its own independent power, cooling, and networking. The multiple
zones are interconnected, allowing for failover capabilities. If one zone experiences a failure, services
can continue to operate in another zone within the same MZR, minimizing downtime and ensuring
business continuity.
Resilience and Disaster Recovery: MZRs are specifically designed to offer a higher level of fault
tolerance compared to single-zone regions. They provide geographic redundancy within the same
region, meaning that workloads can be replicated across different zones, thereby protecting against
zone-level failures.
Interconnected Yet Independent: While the zones within an MZR are interconnected for data
replication and low-latency communication, they are also physically and logically separated to
prevent a single point of failure from affecting multiple zones.
Comparison with Other Options:
Option A is partially correct but does not fully describe an MZR.
Option B is incorrect because a failure in one zone does not affect all other zones.
Option C is incorrect as it does not specify that an MZR consists of multiple zones within the same
geographical region.

A client is using IBM Cloud Schematics to build Infrastructure as Code using a declarative approach.
When using this approach, what does the declarative approach define?
B
Explanation:
In Infrastructure as Code (IaC) using IBM Cloud Schematics, a declarative approach defines the "end
state" or "desired state" of the infrastructure.
Declarative Approach: In the declarative model, you specify the final desired state of the
infrastructure you want, and the IaC tool (IBM Cloud Schematics in this case) takes the responsibility
of determining the sequence of steps necessary to achieve that state. This is opposed to an
imperative approach, where you explicitly define each step required to reach the desired outcome.
IBM Cloud Schematics: IBM Cloud Schematics is a tool that allows users to define their infrastructure
and services as code using Terraform. In a declarative approach, the user creates Terraform
configuration files that describe the desired state of all resources, like VMs, networks, databases, etc.
Schematics then reconciles the current state with the desired state by applying the appropriate
changes.
Reference from IBM Cloud Professional Architect Materials:
According to IBM documentation on IBM Cloud Schematics, it focuses on defining the desired state
(end state) of the resources. This is a fundamental concept of Infrastructure as Code (IaC) and the
declarative approach in cloud computing.
The other options do not accurately describe the declarative approach:
A . Future state is too vague and not a recognized term in the context of IaC.
C . Declarative state is not a defined term in the IaC context.
D . Start state refers to the initial configuration, not the desired outcome.

Which high availability strategy will result in a maximum of 4 nines (99.99%) of availability for an IBM
Kubernetes Services cluster?
D
Explanation:
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.
