Unlock Your Cloud Architect Potential: IBM Cloud Professional Architect v6 C1000-172 Mastery

Correct : B

Volume Replication is a feature of IBM Cloud File Storage (Classic).

IBM Cloud File Storage (Classic): This service provides block-level storage that can be provisioned with different performance tiers. Volume replication allows for synchronous replication of data across different availability zones within a region, ensuring high availability and disaster recovery.

Advantages of Volume Replication: By replicating data, IBM Cloud File Storage (Classic) offers enhanced data durability and continuity in case of an outage or failure at a single storage site.

Reference from IBM Cloud Professional Architect Materials:

According to IBM's documentation on File Storage, volume replication is one of the key features for enabling high availability.

Other options are incorrect:

A . Adjustable Volumes is not a primary feature of the classic version.

C . Jumbo Frames relates to networking, not storage.

D . Fixed IOPS contradicts the flexible performance tiers of IBM Cloud File Storage (Classic).

Correct : D

IBM Cloud Internet Services (CIS) offers a high availability option using range and load balancers.

IBM Cloud Internet Services (CIS): CIS provides security, reliability, and performance for internet-facing applications by offering features like DDoS protection, global load balancing, and content delivery.

High Availability with Load Balancers: CIS uses global load balancing to distribute traffic across multiple servers or data centers, ensuring high availability and minimizing downtime. The range load balancers provide the flexibility to direct traffic efficiently.

Reference from IBM Cloud Professional Architect Materials:

As detailed in IBM's CIS documentation, one of the solutions provided is to ensure high availability through the use of load balancers.

Other options are incorrect:

A . Supporting multi-VLAN and NAT is related to network configuration.

B . Protecting public network, private network, and VLAN is more about network security.

C . Managing from API and portal with appliance GUI relates to management interfaces, not core CIS functionality.

Correct : 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.

Correct : A

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.

Correct : B

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.
