B.   Stores volume data redundantly across multiple physical disks in an availability zone


D.   Provides primary boot volumes and secondary data volumes

Answer DescriptionExplanation:

The capabilities of IBM Cloud Block Storage for VPC are:

Stores Volume Data Redundantly Across Multiple Physical Disks in an Availability Zone: IBM Cloud Block Storage is designed to provide redundancy and durability by storing data across multiple physical disks within the same availability zone. This ensures data availability and protection against disk failures.

Provides Primary Boot Volumes and Secondary Data Volumes: Block Storage in IBM Cloud VPC can be used as both primary boot volumes for the operating system and secondary data volumes for storing additional data.

References from IBM Cloud Professional Architect Materials:

IBM documentation on IBM Cloud Block Storage for VPC outlines these capabilities, including redundant data storage and support for both boot and data volumes.

Other options are incorrect:

A. Provides a highly available, durable, and secure platform for storing unstructured datadescribes object storage, not block storage.

C. Provides storage in a separate zoneis incorrect; storage is typically within the same zone as compute resources.

E. Provides fast, flexible network-attached, NFS-based storagedescribes a different type of storage.

Therefore, the correct answers areB. Stores volume data redundantly across multiple physical disks in an availability zoneandD. Provides primary boot volumes and secondary data volumes.

C.   FedRAMP

Answer DescriptionExplanation:

IBM Cloud follows theFedRAMP (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)andB. 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.

A.   Key management system for data encryption

Answer DescriptionExplanation:

IBM Key Protect is a cloud-based key management service that allows organizations to manage encryption keys used to protect their data across IBM Cloud services. The primary objective of IBM Key Protect is to securely generate, store, manage, and use cryptographic keys to protect sensitive data.

Key Management System:IBM Key Protect provides lifecycle management for keys, including creating, rotating, importing, and deleting keys. This service integrates with various IBM Cloud services to enable secure data encryption and protect data at rest and in transit.

Use Cases:It is designed for organizations that need to ensure compliance with data security regulations and protect their data using industry-standard encryption practices. It provides a centralized key management solution for cloud-native applications and workloads.

Comparison with Other Options:

Hardware security module (B)is a different type of secure key storage, which can be used alongside IBM Key Protect but is not its primary function.

Data analytics platform (C)andCloud-based data storage solution (D)are unrelated to key management and encryption.

B.   A connection point from a VPC to other IBM Cloud services

Answer DescriptionExplanation:

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.

B.   Akamai and Cloudflare

Answer DescriptionExplanation:

IBM Cloud offers two content delivery networks (CDNs): CDN and Cloud Internet Services (CIS). These two offerings are underpinned by the networks of Akamai and Cloudflare, respectively.

IBM Cloud CDN:IBM Cloud uses Akamai’s global network for its Content Delivery Network (CDN) service. Akamai is one of the largest and most trusted CDN providers globally, known for its expansive network that delivers content with low latency and high availability.

IBM Cloud Internet Services (CIS):This service is built on Cloudflare's global network and offers a suite of services, including a CDN, DDoS protection, web application firewall (WAF), and more. Cloudflare's network spans many data centers worldwide, optimizing traffic delivery and securing applications.

Comparison with Other Options:

Limelight and KeyCDN (A), CDN 77 and CloudFront (C), Cloudflare and Fastly (D):These are other CDN providers but do not represent the networks underpinning IBM Cloud's CDN offerings.
