When designing infrastructure for critical business applications, transactional databases, or virtual machines that require low-latency, why might you use Block storage instead of File storage?
- A . Block Storage LUNs can be used for file-based NFS shares
- B . Block Storage LUNs have data at rest encryption using in-house managed keys
- C . Block Storage LUNs can be connected to authorized devices through redundant multi-path I/O (MPIO) connections
- D . Block Storage LUNs can connect to authorized devices in another IBM Cloud datacenter
A PR company is looking to move Windows applications quickly without changing architecture. The company requires physical isolation with regulatory benefit and greater quality of service with control of the software stack.
Which IBM Cloud option would meet these requirements?
- A . Bare Metal Servers
- B . z16
- C . Power
- D . Virtual Servers
A
Explanation:
Bare Metal Servers on IBM Cloud provide the required physical isolation, regulatory benefits, and control over the software stack, making them ideal for moving Windows applications quickly without changing the architecture. Bare Metal Servers offer dedicated hardware resources, full control over the server environment, and the ability to configure and manage the software stack, meeting the company’s needs for physical isolation and performance.
Why Bare Metal Servers? They provide the highest level of performance, security, and customization, including control over the operating system and applications, which is essential for regulatory compliance and quality of service.
Physical Isolation: Bare Metal Servers are single-tenant servers, meaning they are not shared with other customers, providing physical isolation required for specific regulatory needs.
Comparison with Other Options:
z16 (B) and Power (C) are specialized platforms for different workloads, not necessarily suited for general-purpose Windows applications.
Virtual Servers (D): Provide virtualization but do not offer the same level of control and physical isolation as Bare Metal Servers.

A customer has a compute resource in their private datacenter which they need to securely connect to compute resources in the IBM Virtual Private Cloud.
How can this be achieved?
- A . Create a Security Group rule that explicitly blocks any other traffic
- B . Direct all commands via the ibmcloud CLI
- C . Use an IBM Cloud VPN for VPC
- D . Configure a Vyatta Secure Gateway at the VPC entry point
An IT administrator is responsible for selecting the appropriate storage tier for a new application running on IBM Cloud Power Virtual Servers. They need to consider the workload’s peak IOPS and the performance requirements. They are storing data for long-term archival purposes with a minimal I/O load and a peak IOPS requirement of 50.
Which storage tier should they choose?
- A . Tier 5 storage
- B . Tier 2 storage
- C . Tier 3 storage
- D . Tier 1 storage
A
Explanation:
For storing data for long-term archival purposes with a minimal I/O load and a peak IOPS requirement of 50, Tier 5 storage is the most appropriate choice.
Tier 5 Storage: This storage tier is designed for workloads with low performance and IOPS requirements, such as long-term data archival or infrequently accessed data. Tier 5 offers the lowest cost option and is ideal for scenarios where data is rarely accessed, and there is a minimal input/output operation per second (IOPS) requirement.
Workload Suitability: Given that the workload described involves minimal I/O load and a peak IOPS requirement of 50, Tier 5 provides an optimal balance between cost and the minimal performance needed for such an archival workload.
Reference from IBM Cloud Professional Architect Materials:
IBM documentation on IBM Cloud Storage Tiers indicates that Tier 5 storage is suitable for long-term data storage and archival, where performance requirements are minimal.
Other options are incorrect:
B. Tier 2 storage,
C. Tier 3 storage, and
D. Tier 1 storage provide higher performance than necessary for the described archival workload, resulting in potentially unnecessary costs.
Which approach must be used to access worker nodes in an IBM Cloud Red Hat OpenShift Kubernetes Service (ROKS)?
- A . SSH
- B . telnet
- C . IBM Cloud management console
- D . OpenStack API server
A customer RFP is requesting a solution to run a scalable, elastic, and managed analytics focused database with in-memory capabilities.
Which service should be included in the response?
- A . Analytics Engine
- B . DB2 Warehouse on Cloud
- C . Mongo Cluster Service
- D . SQL Query
Which IBM Cloud database service provides transactional support?
- A . Databases for MongoDB
- B . Databases for MySQL
- C . Cloudant
- D . Databases for PostgreSQL
Which service does IBM Cloud Pak for Data utilize to organize data through data classification and governance?
- A . Watson Health Catalog Service
- B . Watson Chat Catalog Service
- C . Watson Data Catalog Service
- D . Watson Knowledge Catalog Service
There is a request to architect a hybrid VMware solution in IBM Cloud to address failures in the on-premise data centers.
What additional VMware component would allow for seamless network access for workloads from the VMware Cluster on-premise to the VMware Cluster in IBM Cloud to facilitate resiliency into existing solutions?
- A . NSX-T
- B . HCX
- C . NCX
- D . NSX-C
Why does IBM Cloud Analytics Engine decouple compute and storage?
- A . Compute can be scaled but storage costs are fixed
- B . Storage can be scaled but not compute
- C . To achieve scale independently and control costs
- D . Compute can be scaled but not 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.
