IBM C1000-172 IBM Cloud Professional Architect v6 Exam Practice Test

Answer : B, D

The capabilities of IBM Cloud Block Storage for VPC are:

Stores Volume Data Redundantly Across Multiple Physical Disks in an Availability Zone: IBM Cloud Block Storage is designed to provide redundancy and durability by storing data across multiple physical disks within the same availability zone. This ensures data availability and protection against disk failures.

Provides Primary Boot Volumes and Secondary Data Volumes: Block Storage in IBM Cloud VPC can be used as both primary boot volumes for the operating system and secondary data volumes for storing additional data.

Reference from IBM Cloud Professional Architect Materials:

IBM documentation on IBM Cloud Block Storage for VPC outlines these capabilities, including redundant data storage and support for both boot and data volumes.

Other options are incorrect:

A . Provides a highly available, durable, and secure platform for storing unstructured data describes object storage, not block storage.

C . Provides storage in a separate zone is incorrect; storage is typically within the same zone as compute resources.

E . Provides fast, flexible network-attached, NFS-based storage describes a different type of storage.

Therefore, the correct answers are B. Stores volume data redundantly across multiple physical disks in an availability zone and D. Provides primary boot volumes and secondary data volumes.

Answer : C

Instance Groups are used to allow provisioning of a large number of virtual server instances at the same time when using IBM Cloud Virtual Private Cloud (VPC).

IBM Cloud VPC Instance Groups: Instance Groups provide a way to manage a group of identical virtual server instances within a VPC. They support auto-scaling, load balancing, and rolling updates, making it easier to manage a large number of instances.

Use Case for Large Deployments: When an organization needs to deploy multiple instances simultaneously, Instance Groups simplify the process by providing a template and scaling policies.

Reference from IBM Cloud Professional Architect Materials:

IBM documentation on Instance Groups for VPC describes how they are used for managing large-scale deployments.

Other options are incorrect:

A . Instance Models refer to the types or configurations of instances, not to mass provisioning.

B . Instance Replication Policies do not exist in this context.

D . Instance Scaling Policies manage scaling but are not used for the initial provisioning of multiple instances.

Answer : D

The likely reason IBM Log Analysis is missing the Red Hat OpenShift on IBM Cloud instance logs is that the logging agents were not created and deployed to this OpenShift instance.

IBM Log Analysis with Sysdig: To collect logs from a Red Hat OpenShift cluster, specific logging agents must be deployed on the cluster. These agents are responsible for forwarding logs to the IBM Log Analysis service.

Missing Logs Due to Missing Agents: If the agents are not deployed, the service will not capture logs from the cluster, resulting in missing log data from that instance.

Reference from IBM Cloud Professional Architect Materials:

IBM documentation on Setting up Log Analysis explains the requirement of deploying logging agents to the respective resources to ensure log collection.

Other options are incorrect:

A . The developer needs at least editor IAM role does not affect the log capture.

B . The administrator needs at least reader access does not address the missing agents.

C . The instance running in a different region does not prevent log capture if agents are configured correctly.

Answer : A

IBM API Connect offers both authentication and authorization capabilities to secure APIs using OAuth and OpenID.

IBM API Connect Security Features: IBM API Connect provides built-in capabilities for managing OAuth and OpenID Connect authentication and authorization flows. It allows users to define security policies that enforce these protocols to protect APIs.

Use of OAuth and OpenID: API Connect enables organizations to create user registries, apply security policies, and manage tokens for OAuth 2.0 and OpenID Connect, providing end-to-end security management for APIs.

Reference from IBM Cloud Professional Architect Materials:

IBM documentation on API Security in IBM API Connect confirms that API Connect handles both authentication and authorization for securing APIs.

Other options are incorrect:

B . IBM API Connect APIs must be secured by a third party is false; API Connect itself provides these capabilities.

C . IBM API Connect is providing authentication, but authorization can be provided by IAM is incorrect because API Connect manages both.

D . IBM API Connect creates user registries, but OAuth isn't allowed is incorrect; OAuth is fully supported.

Answer : C

IBM Cloud Transit Gateway provides the ability to provision and define connections between resources on the IBM Cloud network.

IBM Cloud Transit Gateway: This service allows you to connect multiple Virtual Private Clouds (VPCs) and on-premises networks to a central gateway. It simplifies network management by providing a single entry point for interconnecting multiple resources across the IBM Cloud.

Connectivity Between Resources: By creating connections through the Transit Gateway, an organization can establish a scalable and flexible network architecture that integrates various cloud resources.

Reference from IBM Cloud Professional Architect Materials:

According to IBM documentation on IBM Cloud Transit Gateway, it provides centralized management and provisioning of connections across different IBM Cloud environments.

Other options are incorrect:

A . Client designates which traffic remains within the private IBM Cloud backbone is not specifically managed by the Transit Gateway.

B . Provides private interconnectivity for on-premises workloads and the designated VPC is more related to Direct Link.

D . Provides a decentralized hub for better regional connectivity and load balancing is incorrect since Transit Gateway is a centralized solution.

Answer : A

IBM Cloud Analytics Engine supports several programming languages for developing big data analytics. The correct answer is Java, Scala, Python, and R.

IBM Cloud Analytics Engine: This service provides a fully managed Apache Spark service designed to handle big data analytics. Apache Spark, the core engine behind IBM Cloud Analytics Engine, supports multiple programming languages like Java, Scala, Python, and R to build, test, and deploy big data applications.

Supported Languages: According to the IBM Cloud Analytics Engine documentation, developers can use Java, Scala, Python, and R to interact with Spark. This flexibility allows data scientists and engineers to use the language they are most comfortable with or that best suits their project requirements.

Why Other Options are Incorrect:

B . Scala, Python, and R is incomplete as it omits Java.

C . Python and R only is incorrect since it excludes both Java and Scala.

D . C, C++, Java, Scala, Python, and R is incorrect because C and C++ are not supported by Apache Spark in this context.

Answer : C

IBM Cloud Transit Gateway provides network connectivity between different IBM Cloud Virtual Private Clouds (VPCs). It allows for secure, scalable, and efficient communication between resources deployed in separate VPCs, whether they are within the same region or across different regions.

How Transit Gateway Works: It acts as a central hub that facilitates the routing of traffic between multiple VPCs without the need to configure individual VPC peering connections. This simplifies network management, improves scalability, and enhances security by maintaining a single point of control.

Benefits of Transit Gateway: This service supports both private and public connectivity options and allows for routing policies that can be customized according to business needs. It also provides seamless integration with other IBM Cloud services and third-party networks.

Comparison of Other Options:

Domain Name System (A): Not used for network connectivity between VPCs.

Direct Link (B): Used for dedicated, high-speed connections from on-premises to IBM Cloud but not between VPCs.

Power Edge Router (D): Not an IBM Cloud service for inter-VPC connectivity.
