An application team notices high latency when their cloud-based fraud detection AI queries the legacy mainframe database on-premises.
How does a "Hybrid Cloud" architecture pattern using IBM Cloud Satellite specifically address this "Physics of Data" problem?
- A . It forces the mainframe to move to the public cloud.
- B . It allows the fraud detection AI service (e.g., OpenShift workloads) to be deployed physically close to the data (in the on-prem data center) via a Satellite Location, eliminating the network hop while still being managed as a cloud service.
- C . It compresses the database to make it smaller.
- D . It increases the speed of light to reduce network latency.
A "Digital Bank" (Consumer) wants to launch a new feature using a third-party "Identity Verification" SaaS (Provider).
Both parties are target clients of IBM Cloud for Financial Services.
What shared architectural component connects them securely?
- A . IBM Cloud Transit Gateway / Private Backbone: The SaaS provider exposes their service via private endpoints (like VPE/Private Path), allowing the bank to consume the service entirely over the IBM private network without traversing the public internet.
- B . The Public Internet: They connect via standard public APIs.
- C . Email: Data is exchanged via encrypted ZIP files.
- D . Physical Cables: The bank runs a cable to the SaaS provider’s office.
The "Revised Payment Services Directive" (PSD2) mandates that banks provide third-party providers (TPPs) access to customer account data via secure APIs.
Which technical architecture component is most critical for meeting this specific regulatory standard while maintaining security?
- A . A read-only replica of the core database exposed directly to the public internet.
- B . A block storage volume shared via NFS.
- C . A bare metal server running a legacy monolithic application.
- D . An API Gateway with strong authentication (OIDC/OAuth) and rate limiting.
A bank is designing a new "Open Banking" platform to allow third-party fintechs to retrieve customer account data via APIs, as mandated by new government regulations (e.g., PSD2).
This initiative introduces a conflict between two opposing industry challenges.
Which pair correctly identifies this conflict? (Choose 2.)
- A . The mandate to open up data interfaces (Open Banking / Interoperability).
- B . The need to stop using computers and return to paper ledgers.
- C . The mandate to protect customer data privacy and prevent unauthorized access (Security / Zero Trust).
- D . The need to reduce the number of customers to save money.
- E . The need to increase the physical size of data centers.
A DevOps team is attempting to migrate a monolithic application to a microservices architecture on IBM Cloud. During the "strangler fig" modernization process, they encounter intermittent connection failures between the new cloud-native microservices and the legacy on-prem database.
Review the latency metrics captured during troubleshooting:
Source: "app-microservice-us-south"
Destination: "db-legacy-on-prem"
Round_Trip_Time_Avg: "65ms"
Application_Timeout_Setting: "50ms"
Connection_Type: "Site-to-Site VPN"
Based on these dependency metrics, what is the primary technical barrier to this modernization effort?
- A . The microservice is running on an incompatible operating system.
- B . The database is rejecting connections because the source IP is from a public cloud range.
- C . The application timeout is set too low for the physical distance and connectivity method (VPN) being used.
- D . The Site-to-Site VPN is encrypting the traffic, which corrupts the database queries.
"Vendor Lock-in Risk" is a systemic concern for financial regulators (like the EBA or PRA) who require banks to have an "Exit Strategy."
How does the use of Red Hat OpenShift on IBM Cloud mitigate this specific portability risk?
- A . Data Formats: OpenShift converts all data into a format readable only by IBM DB2.
- B . Proprietary APIs: OpenShift uses secret APIs that only work on IBM hardware.
- C . Contractual Lock-in: IBM requires a 10-year contract for OpenShift.
- D . Container Abstraction: OpenShift provides a consistent, portable container platform based on open-source Kubernetes. Applications built for OpenShift on IBM Cloud can be moved to OpenShift on-premises or another cloud provider with minimal refactoring, ensuring the bank is not technically locked into a proprietary IBM runtime.
A partner is attempting to submit their application for validation but is being rejected.
Review the assessment feedback:
Status: "Rejected"
Control_ID: "CRYPTO-01"
Requirement: "Customer Managed Keys (KYOK)"
Finding: "Application uses default provider-managed encryption keys for the database."
What specific action must the partner take to meet the validation requirement and resolve this finding?
- A . Change the status in the report to "Approved" manually.
- B . Delete the database and store data in a flat text file.
- C . Reconfigure the application’s database to use Hyper Protect Crypto Services (HPCS) for root key management, enabling the KYOK model required by the framework.
- D . Provide a written letter promising to encrypt the data next year.
A user is trying to add a colleague to the IBM Cloud support portal to allow them to open tickets.
Does the support tier level (Basic vs. Premium) affect who within the client’s organization is allowed to open a case?
- A . Yes: On Premium plans, only the CEO can open tickets.
- B . Yes: Developers are blocked from support on all plans.
- C . No: Access to the Support Center is controlled by IAM Access Policies (e.g., the "Editor" or "Administrator" role on the Support service). Any user with the correct IAM permission can open a case, regardless of whether the account is Basic or Premium.
- D . Yes: On Basic plans, only the Account Owner can open tickets.
A bank needs to decommission a sensitive dataset stored in the cloud to meet the "Right to Erasure" (GDPR) or simply to retire an asset. They face the risk of "Data Remanence" (data lingering on physical media).
Using IBM Cloud Hyper Protect Crypto Services (HPCS), what is the most effective mitigation strategy to ensure the data is unrecoverable ("Crypto-Shredding")?
- A . Overwrite the disk 7 times: Requesting IBM to manually wipe the physical platters.
- B . Delete the Master Key (CRK): By destroying the Customer Root Key in the HSM, all data encrypted by that key (and its associated DEKs) becomes instantly and permanently mathematically unreadable, regardless of where the encrypted bits reside.
- C . Format the volume: Reformatting the file system.
- D . Delete the file from the OS: Running rm -rf on the server.
Which IBM Cloud monitoring tool is capable of ingesting "Network Flow Logs" and "Activity Tracker Events" to provide a correlated view of a security incident?
- A . IBM Cloud Secrets Manager: Manages keys.
- B . IBM Cloud Internet Services: Manages edge traffic.
- C . IBM Cloud Direct Link: Manages physical connections.
- D . IBM Cloud Security and Compliance Center (SCC) (Workload Protection/Threat Detection module): While primarily for posture, the advanced Threat Detection capabilities (often powered by Sysdig Secure technology integrated into the platform) can analyze runtime events and network flows to detect anomalies.
