Question #1
Which OSI Layers does IBM Cloud Direct Link utilize?
- A . Layers 2 and 3
- B . Layers 1 thru 7
- C . Layers 3 and 4
- D . Layers 1 and 2
Correct Answer: A
A
Explanation:
IBM Cloud Direct Link utilizes Layers 2 and 3 of the OSI model.
Layer 2 (Data Link Layer) and Layer 3 (Network Layer): IBM Cloud Direct Link provides private connectivity from an on-premises data center to the IBM Cloud through dedicated connections. At Layer 2, it provides direct network paths, while at Layer 3, it handles routing between networks.
Direct Link Functionality: Direct Link offers high-performance, secure connectivity options for hybrid cloud solutions, making it an essential service for enterprises that require a secure and efficient connection to the IBM Cloud.
Reference from IBM Cloud Professional Architect Materials:
The IBM Cloud Direct Link documentation specifies that it operates at OSI Layers 2 and 3 to provide dedicated connectivity options.
Other options are incorrect:
B. Layers 1 thru 7 encompasses all OSI layers, which is incorrect.
C. Layers 3 and 4 include the transport layer, which Direct Link does not utilize directly.
D. Layers 1 and 2 omits Layer 3, which is crucial for network routing.

Question #2
A global manufacturing company has multiple facilities across the world. It runs its business on dispersed IBM Power hardware and as part of a refresh program wants to consolidate its IT footprint.
Which benefit of IBM Power System Virtual Servers meets this use case?
- A . Disaster Recovery and Business Continuity
- B . Centralized IT Infrastructure Management
- C . Development and Testing Environments
- D . High-Performance Computing
Correct Answer: B
B
Explanation:
IBM Power System Virtual Servers offer centralized IT infrastructure management, which is beneficial for a global manufacturing company looking to consolidate its IT footprint. By moving workloads to IBM Power System Virtual Servers, the company can manage its global IT resources from a single platform, simplifying operations, reducing costs, and increasing operational efficiency.
Benefits of Centralized Management: Consolidating IT infrastructure under a single, centrally managed platform allows for more streamlined operations, consistent management practices, and a reduction in the complexity associated with managing multiple dispersed systems.
Why This Benefit Meets the Use Case: The company needs to consolidate its IT footprint, which requires reducing the number of disparate systems and consolidating management under a single pane of glass.
Comparison with Other Options:
A (Disaster Recovery): Relevant but not the primary benefit in this use case.
C (Development and Testing): Does not align with the need to consolidate IT infrastructure.
D (High-Performance Computing): Not the primary goal described in the use case.

Question #9
Which IBM Cloud service can be used to store and analyze data collected to identify the root causes of slowness?
- A . Databases for etcd
- B . Databases for Redis
- C . Databases for Elasticsearch
- D . Cloudant
Correct Answer: C
C
Explanation:
Elasticsearch is a powerful search and analytics engine commonly used to store, search, and analyze large volumes of data in real time. IBM Cloud’s "Databases for Elasticsearch" service is specifically designed for this purpose, allowing users to ingest, search, and analyze log data or other large datasets to identify root causes of slowness or performance issues.
Why Databases for Elasticsearch? Elasticsearch is ideal for storing and analyzing logs due to its ability to quickly index and query large amounts of data. It provides powerful search capabilities, aggregations, and visualization tools that are well-suited for identifying performance bottlenecks and troubleshooting.
Comparison with Other Options:
A (Databases for etcd): Not used for analytics or identifying performance issues.
B (Databases for Redis): Primarily an in-memory data store, not suitable for complex data analysis.
D (Cloudant): A NoSQL database service optimized for web and mobile applications, but not primarily for analyzing log data.
