IBM C1000-172 Exam Questions

For data with unpredictable usage patterns, the architect should select the Smart Tier storage class.

Smart Tier Storage Class: This is designed for workloads with changing or unpredictable access patterns. It automatically moves data between different cost-performance tiers based on access patterns, providing cost-efficiency and optimal performance without requiring manual intervention.

Unpredictable Usage Patterns: Smart Tier is particularly beneficial when the usage patterns of data are not consistent, as it dynamically adjusts the storage tier to ensure the most efficient use of resources.

Reference from IBM Cloud Professional Architect Materials:

IBM's documentation on IBM Cloud Object Storage Classes describes Smart Tier as the recommended choice for data with unpredictable access patterns.

Other options are incorrect:

A . Standard is for frequently accessed data.

C . Vault and D. Cold Vault are for infrequently accessed data, not suitable for unpredictable usage.

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.

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.

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.

File Storage (Classic) on IBM Cloud allows users to adjust the performance as needed by choosing different tiers or adjusting the input/output operations per second (IOPS). This flexibility makes it suitable for workloads with varying performance requirements, such as databases, analytics, or content management systems, where the storage performance can be adjusted to match the workload demand.

Performance Adjustability: Users can choose between various performance levels or make adjustments to IOPS, allowing them to balance cost and performance based on current needs.

Why File Storage (Classic)? This flexibility makes File Storage (Classic) suitable for dynamic workloads that require changes in performance over time, such as during peak usage periods.

Comparison with Other Options:

Protects against data in transit failures (B) is not a primary feature of File Storage.

Scalable during provisioning (C) is partially correct, but 'adjusting performance' is more precise.

Asynchronous reads and writes (D) are general file system features, not unique to IBM Cloud File Storage.
