Free Practice Questions for IBM C1000-142 Exam

SSL (Secure Socket Layer) allows information to travel from browser to server and back again using a secured transmission tunnel to combat eavesdropping. Verification amount depends on the style of SSL certificate involved. You can manage your SSL certificates in the IBM Cloud® console. Within the IBM Cloud console, all SSL certificates ordered through IBM Cloud can be managed from the SSL Orders screen. This screen tracks all orders, including the common name, certificate type, and expiration date of the certificate but does not contain any certificate-specific details such as the certificate itself or the Private Key. From this screen, current and expired SSL certificates can be renewed under their pre-existing terms, and fulfillment emails can be requested to receive the SSL certificate details if they are lost. All requests that are made from the SSL Orders screen are routed to the appropriate certificate authority for the SSL certificate, which fulfills the requests as necessary. Because IBM Cloud does not possess the SSL certificate details, IBM Cloud is unable to provide any additional information about the certificate.

Correct Answer : True Software as a service (SaaS) is a service model, where you use the software applications over the Internet provided by cloud provider, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure, and they also handle any maintenance, such as software upgrades and security patching. Examples : Gmail, Google DOC Organizations are using SaaS (Software-as-a-Service) to avoid the need for ongoing upgrades, maintenance, and patching, in SaaS model, cloud provider offer compete software as a service over the internet to users (Example- Google Doc, Gmail). In this model, Software or Application are centrally hosted and delivered over the internet under licensed on a subscription.

IBM Cloud Developers are responsible for writing code to create and maintain cloud applications.

Explanation

Correct Answer : Metro : The name of a city where 1 or more data centers are located. A metro might have a multizone region, such as Dallas, or might have a single zone region, such as Mexico City. If you create a cluster in a multizone region, the Kubernetes master and worker nodes can be spread across zones for high availability. In-Correct Answers: Geography : An organizational grouping that is based on geographic continents. Note : District & Urban site are not valid options for IBM Cloud - these are added for distraction.

Hybrid Cloud combines public cloud, private cloud and on-premises infrastructure to create a single, flexible, cost-optimal IT infrastructure. Hybrid Cloud model best suits where security and regulatory compliance required. Use Cases : Security and regulatory compliance: We can reserve sensitive data and highly regulated workloads behind-the firewall in private cloud and can use more economical public cloud resources for less-sensitive workloads and data. Resource optimization, and cost savings: We can manage predictable capacity workload on private cloud and can migrate unpredictable workloads to public cloud to scale up quickly and automatically. Cloud Scaling : A business has on-premise infrastructure that can handle a certain amount of user load. The hybrid allows them to scale up in response to a larger load then automatically de-provision resources when they no longer need them. Multicloud: Composite cloud are applications that are spread across multiple cloud environments. If a business has on-premise architecture that allows them to run three components of their app but the system gets bogged down in busier times, such as holidays, they take advantage of the multicloud architecture by composing their application across multiple cloud environments. In-Correct Answers - Full control over hardware and software choices : In Private cloud, customer have full control over IT infrastructure, They are free to purchase the hardware and software as per their choice. They can customize(configure) servers and software as needed. - Greater visibility into security and access control, In Private Cloud, all workloads run behind the customers’ own firewall. - Greater elasticity and scalability: With public cloud, a customer can add capacity in response to unexpended surges in traffic, without purchasing and installing new hardware. [Exam Tips] : You can expect few questions from here in your exam, so before appearing for exam, you should be aware of use cases of private, public and hybrid cloud.

Explanation

Continuous Integration checks that the application is not broken whenever new commits are integrated into the main branch; prevents significant drift, competing changes, and merge conflicts.

IBM Cloud Internet Services provides reliability, performance, and security for Internet facing applications, websites, and services. One of the services Cloud Internet Services provides is a global load balancer. This service enables traffic to be distributed across multiple servers located in multiple regions. Using Cloudflare, Cloud Internet Services (CIS) provides Domain Name Service (DNS), Global Load Balancer (GLB), DDoS protection, Web Application Firewall (WAF), Transport Layer Security (TLS), Rate Limiting, Smart Routing, and Caching.

IBM Cloud Transit Gateway helps you connect and manage your IBM Cloud Virtual Private Cloud (VPC) networks. Note : A virtual private cloud (VPC) is a private cloud within a public cloud.
