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

Answer : B

The IBM Cloud services that can help in building a solution for collecting, transforming, and analyzing data from different formats are Event Streams and App Connect.

IBM Event Streams: This is an Apache Kafka-based messaging service designed to handle real-time data streaming and ingestion. It can collect and distribute data from various sources, making it suitable for scenarios involving data from multiple sources or formats.

IBM App Connect: App Connect provides integration capabilities that allow for data transformation, mapping, and filtration, enabling the unification of data formats before processing. It helps in creating rules to transform data according to the desired structure.

Reference from IBM Cloud Professional Architect Materials:

IBM documentation on Event Streams and App Connect describes how these services can work together to handle and transform data from multiple sources for real-time analytics and integration.

Other options are incorrect:

A . API Connect and Aspera focus on API management and high-speed data transfer, respectively.

C . Event Streams and Aspera are not geared towards data transformation and integration.

D . App Connect and Datastax do not provide the necessary data streaming and collection capabilities.

Answer : C

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.

Answer : B

The Global Routing option of IBM Cloud Direct Link offers private network connectivity to IBM Cloud services across multiple regions.

IBM Cloud Direct Link: This service provides dedicated private network connectivity from your on-premises environment to the IBM Cloud. The Global Routing option allows data to be transmitted securely across multiple IBM Cloud regions, ensuring low latency and high-speed connectivity for global deployments.

Global Connectivity: With the Global Routing option enabled, organizations can connect to IBM Cloud services in multiple regions without needing separate connections for each region, simplifying network management and improving performance.

Other options are incorrect:

A . Public Routing option does not provide private network connectivity.

C . Semi Private Routing option is not a recognized option.

D . Private Routing option offers connectivity within a single region rather than multiple regions.

Answer : A

IBM Cloud Hyper Protect Crypto Services is built on FIPS 140-2 Level 3-certified hardware.

FIPS 140-2 Level 3 Certification: This level of certification ensures that the hardware used by IBM Cloud Hyper Protect Crypto Services provides a high degree of security, including physical tamper-resistance and the use of strong encryption protocols.

IBM Hyper Protect Crypto Services: These services leverage Hardware Security Modules (HSMs) that meet the FIPS 140-2 Level 3 certification. The HSMs provide a secure environment for key management and cryptographic operations, which is critical for meeting stringent regulatory and compliance requirements.

Reference from IBM Cloud Professional Architect Materials:

Detailed information on IBM Cloud Hyper Protect Crypto Services and its use of FIPS 140-2 Level 3-certified hardware can be found in IBM documentation on IBM Cloud Hyper Protect Crypto Services.

Other options are incorrect:

B . NIST 140-2 Level 5-certified hardware and D. NIST 140-2 Level 2-certified hardware are not valid terms.

C . FIPS 140-2 Level 4-certified hardware would be a higher certification level than is currently used.

Answer : B

The IBM Gateway Appliance provides Network Address Translation (NAT) capability.

IBM Gateway Appliance: It offers advanced network capabilities, including Network Address Translation (NAT). This feature allows for the mapping of private IP addresses to a single public IP address or multiple public IP addresses, enabling private IP addresses within an organization's internal network to be hidden from the external world, thereby enhancing security.

Why Other Options are Incorrect:

A . Wide Area Network and D. Local Area Network refer to types of networks, not specific functionalities of the IBM Gateway Appliance.

C . Offline upload is unrelated to the gateway appliance's networking capabilities.

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.

Answer : D

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.
