IBM Cloud Professional Architect v6 C1000-172 Exam Questions

Answer : B

An IBM Cloud Virtual Private Endpoint (VPE) provides a connection point from a Virtual Private Cloud (VPC) to other IBM Cloud services. This allows secure, private communication between resources within a VPC and IBM Cloud services without traversing the public internet, enhancing security and performance.

What is a Virtual Private Endpoint? VPE is a mechanism that enables private connections from a VPC to supported IBM Cloud services such as databases, object storage, and others. It eliminates the need for public IP addresses and reduces the exposure to potential attacks over the public internet.

Why This Option Describes VPE: It clearly explains that VPE is for connecting VPC resources to other IBM Cloud services, fitting the purpose of secure, internal cloud communication.

Comparison with Other Options:

A (Classic to microservices), C (VPC to on-premises), D (Classic to on-premises): None accurately describe the function of a Virtual Private Endpoint in IBM Cloud.

Answer : C

IBM Cloud follows the FedRAMP (Federal Risk and Authorization Management Program) to ensure its services meet the security and compliance standards of the US government.

FedRAMP: It is a U.S. government-wide program that provides a standardized approach to security assessment, authorization, and continuous monitoring for cloud products and services. FedRAMP authorization is mandatory for any cloud services used by federal agencies, ensuring they meet strict security requirements.

IBM Cloud Compliance: IBM Cloud adheres to FedRAMP standards to provide its services to government agencies, ensuring that its cloud solutions meet stringent security and compliance requirements, as documented in IBM's FedRAMP Certification.

Why Other Options are Incorrect:

A . CIS (Center for Internet Security) and B. NIST (National Institute of Standards and Technology) are frameworks and standards organizations but not specific programs like FedRAMP.

D . FIPS (Federal Information Processing Standards) defines security and interoperability standards but does not pertain to the overall authorization of cloud services.

Answer : A

The feature of Cloud Internet Services (CIS) being discussed is Security.

CIS Security Features: IBM Cloud Internet Services provides robust security measures to protect internet-facing applications from a variety of attacks, including Distributed Denial of Service (DDoS), data theft, and bot attacks. These services are crucial for securing applications and data in the cloud.

Protection Mechanisms: CIS integrates multiple layers of security features, such as Web Application Firewall (WAF), DDoS protection, and threat intelligence, which work together to secure applications from cyber threats.

Reference from IBM Cloud Professional Architect Materials:

The IBM Cloud Internet Services documentation highlights the focus on security to protect applications from DDoS attacks, data breaches, and other threats.

Other options are incorrect:

B . Performance relates to speed and efficiency, not protection.

C . Reliability deals with system uptime and consistency.

D . Scalability is about handling increased load, not security.

Answer : C

IBM Cloud Transit Gateway provides the ability to provision and define connections between resources on the IBM Cloud network.

IBM Cloud Transit Gateway: This service allows you to connect multiple Virtual Private Clouds (VPCs) and on-premises networks to a central gateway. It simplifies network management by providing a single entry point for interconnecting multiple resources across the IBM Cloud.

Connectivity Between Resources: By creating connections through the Transit Gateway, an organization can establish a scalable and flexible network architecture that integrates various cloud resources.

Reference from IBM Cloud Professional Architect Materials:

According to IBM documentation on IBM Cloud Transit Gateway, it provides centralized management and provisioning of connections across different IBM Cloud environments.

Other options are incorrect:

A . Client designates which traffic remains within the private IBM Cloud backbone is not specifically managed by the Transit Gateway.

B . Provides private interconnectivity for on-premises workloads and the designated VPC is more related to Direct Link.

D . Provides a decentralized hub for better regional connectivity and load balancing is incorrect since Transit Gateway is a centralized solution.

Answer : C

A security feature of IBM Cloud VPN for virtual private cloud (VPC) service is Perfect Forward Secrecy (PFS).

Perfect Forward Secrecy (PFS): PFS ensures that the compromise of one session key does not compromise the confidentiality of past sessions. It provides additional security for encrypted communications by generating unique keys for each session, making it a critical feature for VPN services.

IBM Cloud VPN for VPC: This service utilizes PFS to secure communication between the cloud environment and external networks, ensuring high levels of data protection and encryption.

Reference from IBM Cloud Professional Architect Materials:

The IBM documentation on IBM Cloud VPN describes PFS as a fundamental security feature for protecting data transmitted over the network.

Other options are incorrect:

A . Passive Peer Detection is not a security feature.

B . RSA key exchange is a cryptographic algorithm but does not describe a VPN-specific security feature.

D . Post-shared key is not a relevant term.

Answer : D

The likely reason IBM Log Analysis is missing the Red Hat OpenShift on IBM Cloud instance logs is that the logging agents were not created and deployed to this OpenShift instance.

IBM Log Analysis with Sysdig: To collect logs from a Red Hat OpenShift cluster, specific logging agents must be deployed on the cluster. These agents are responsible for forwarding logs to the IBM Log Analysis service.

Missing Logs Due to Missing Agents: If the agents are not deployed, the service will not capture logs from the cluster, resulting in missing log data from that instance.

Reference from IBM Cloud Professional Architect Materials:

IBM documentation on Setting up Log Analysis explains the requirement of deploying logging agents to the respective resources to ensure log collection.

Other options are incorrect:

A . The developer needs at least editor IAM role does not affect the log capture.

B . The administrator needs at least reader access does not address the missing agents.

C . The instance running in a different region does not prevent log capture if agents are configured correctly.

Answer : B

Client-managed encryption allows clients to have full control over the encryption keys used to protect their block storage volumes, file shares, and custom images on IBM Cloud. This option ensures that only the client has access to the keys and, therefore, to the data.

Benefits of Client-Managed Encryption: Clients retain control over key management, including generation, rotation, and deletion, ensuring compliance with security policies and regulatory requirements.

Comparison with Other Options:

A (Provider-managed encryption): Managed by IBM, not by the client.

C (IBM-managed encryption): Similar to provider-managed, where IBM controls the keys.

D (Custom encryption): Not a specific term used in IBM Cloud documentation for this feature.
