IBM Cloud Transit Gateway provisions and defines connections between resources on the IBM Cloud network, providing private interconnectivity between IBM Cloud data centers worldwide. IBM Cloud Transit Gateway provides a central hub for connectivity, making it easier to provision and manage your networks. With IBM Cloud Transit Gateway, you can create a single transit gateway or multiple transit gateways to connect IBM Cloud VPCs. You can also connect your IBM Cloud classic infrastructure to a transit gateway to provide seamless communication with classic infrastructure resources. Any new resource that you connect to a transit gateway is automatically made available to every other resource connected to it. All data remains within the private IBM Cloud backbone and is optimized for performance. IBM Cloud Transit Gateway supports local and global routing between VPCs and the IBM Cloud classic infrastructure. Connections to and from an IBM Cloud Transit Gateway on the IBM private network are not shown to the public internet. This arrangement reduces public egress and VPN costs and reduces security threats. IBM Cloud Transit Gateway is a fully redundant, fault-tolerant service with no single point of failure within IBM Cloud multizone regions. In-Correct Answer : The following offerings help you interconnect a VPC with an on-premises network VPN can securely connect your virtual private cloud to another private network. You can use VPN to set up an IPsec site-to-site tunnel between your VPC and your on-premises private network or another VPC IBM Cloud Direct Link Connect provides connectivity between your on-premises and IBM Cloud VPC networks through a supported service provider. A service provider connection is useful if your data center is in a physical location that can't reach a dedicated colocation facility, or if your data needs don't warrant a 5 Gbps+ connection. Connect service providers are often used to facilitate multicloud connectivity (public clouds from multiple vendors) through their network. Connect service providers offer layer 2 connectivity, layer 3 connectivity, or both. Work with your service provider to understand their offerings and requirements. IBM Cloud Direct Link Dedicated provides low-latency, high-throughput connections between IBM Cloud VPC networks direct to a service provider-managed WAN, or a client-managed cloud backbone. You can optimize egress traffic from your VPC network and reduce your egress costs. If you can’t connect at an IBM Cloud data center, or don’t need more than 5 Gbps of bandwidth on a Virtual Network Connection, you can use IBM Cloud Direct Link Connect to connect to IBM Cloud through a supported service provider. [Exam tips]: Remember IBM Cloud Transit Gateway used to connect internal VPCs(VPC-to-VPC). IBM Cloud provides connectivity from an external source into a customer's IBM Cloud private network. IBM Cloud Transit Gateway provides connectivity between resources within a customer's IBM Cloud private network.

Virtualization is a process that allows for more efficient utilization of physical computer hardware and is the foundation of cloud computing.

Types of virtualization:

CPU (central processing unit) virtualization is the fundamental technology that makes hypervisors, virtual machines, and operating systems possible. It allows a single CPU to be divided into multiple virtual CPUs for use by multiple VMs.

Application virtualization runs application software without installing it directly on the user’s OS. This differs from complete desktop virtualization (mentioned above) because only the application runs in a virtual environment—the OS on the end user’s device runs as usual. There are three types of application virtualization:

Local application virtualization: The entire application runs on the endpoint device but runs in a runtime environment instead of on the native hardware.

Application streaming: The application lives on a server which sends small components of the software to run on the end user's device when needed.

Server-based application virtualization The application runs entirely on a server that sends only its user interface to the client device.

Data center virtualization abstracts most of a data center’s hardware into software, effectively enabling an administrator to divide a single physical data center into multiple virtual data centers for different clients.

Each client can access its own infrastructure as a service (IaaS), which would run on the same underlying physical hardware. Virtual data centers offer an easy on-ramp into cloud-based computing, letting a company quickly set up a complete data center environment without purchasing infrastructure hardware.

DevOps is an approach to lean and agile software delivery that promotes closer collaboration between lines of business, development and IT operations.

Containers are lightweight and portable executable units (images) of software. They supply portability between different platforms and clouds. Containers are self-contained units that are designed to hold applications as well as all libraries and dependencies that the application requires. Containers can be run on physical computers or in the cloud.

Containers do not have an operating system of their own. Instead, they access the operating system of the device they are running on using a hypervisor. This allows them to be more light-weight, easier to provision, and much smaller than traditional virtual machines.

Virtual machine is a virtual re-presentation of physical computer, you can understand it as a computer inside a computer. Each individual virtual machine behaves exactly as though it were its own computer. It has its own operating system, memory, storage, and compute and is totally unaware of other virtual machines that could be running on the same host.

How do containers differ from a traditional VM?

Traditional virtualization leverages a hypervisor to virtualize physical hardware. Each VM contains:

- A guest operating system (OS)

- A virtual copy of the hardware that the OS requires to run

- An application and its associated libraries and dependencies

- Containers, on the other hand, virtualize the operating system. Each container only contains:

- The application

- Its libraries

- Its dependencies

IBM Cloud® Identity and Access Management (IAM) provides secure access control that enable developers to do all sorts of useful things. For example, if an organization’s corporate security policies require that IBM Cloud credentials always be encrypted and rotated every week, developers can use IAM to securely provide credentials that write to the Cloudant Service.

IAM policy enables a subject to access a resource. There are three primary values in a policy: a subject, roles, and resources.

Multi Cloud is a combination of two or more cloud services from different cloud providers. In-Correct Answers : Private Cloud : The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community Cloud : The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Public Cloud : The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. Hybrid Cloud : The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

IBM Cloud Paks are: Portable and can run anywhere: The portability of hybrid cloud solutions built with IBM Cloud Paks means that they are built to run on any hybrid cloud environment.

Correct Answer:

Explanation

An ACL lists rules that define which source IP addresses can access a particular subnet in a VPC. Access control list rules are prioritized and determined in sequence. ACLs manage ingress and egress traffic for a subnet. It is stateless, meaning that the traffic rules must be specific, separate, and explicit. Each ACL has rules that are based on the following: - Source IP - Source port - Destination IP - Destination port - Protocol Every VPC will have a default ACL to control ingress and egress traffic but by default, all traffic is allowed in and out. These ACLs can be modified or customized and attached to the subnets. A subnet is only able to have one ACL attached to it, but you can attach an ACL to multiple subnets.

IBM Cloud® for VMware Solutions Shared uses VMware Cloud Director to enable you to extend your VMs to the cloud with ultimate capacity and scalability, while paying only for what is consumed. With IBM managing the infrastructure up to the hypervisor, you don’t need to worry about providing updates and patching, and instead can focus on application innovation. Use Cases : Development and test, Temporary workload migration, Cost-effective disaster recovery. Note : RTO is the maximum amount of time the organization can afford to be without access to the data or application. In other words, how quickly the customer needs to recover the data and application. RPO is the amount of data an organization can afford to lose and effectively dictates how frequently they need to back up their data to avoid losing more.

Block and file storage are common in traditional data centers but can often struggle with scale, performance and distributed characteristics of cloud. Thus, of the three, object storage has thus become the most common mode of storage in the cloud given that it is highly distributed (and thus resilient), it leverages commodity hardware, data can be accessed easily over HTTP, and scale is not only essentially limitless but performance scales linearly as the cluster grows.

Application virtualization: Application virtualization runs application software without installing it directly on the user’s OS. This differs from complete desktop virtualization (mentioned above) because only the application runs in a virtual environment—the OS on the end user’s device runs as usual. There are three types of application virtualization:

Local application virtualization: The entire application runs on the endpoint device but runs in a runtime environment instead of on the native hardware.

Application streaming: The application lives on a server which sends small components of the software to run on the end user's device when needed.

Server-based application virtualization : The application runs entirely on a server that sends only its user interface to the client device.

Question 31: 

Which statement is true regarding serverless computing?

A. Users are charged a low hourly rate during idle time for the serverless computing service

B. Implementations differ across service providers, and capabilities vary, including supported runtimes, authentication, scaling and monitoring

C. Serverless application are generally long-running (days or weeks) and maintain state or information across requests

D. Serverless is not well-suited for event processing or IOT

Answer: B

Explanation

Serverless computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto-scalable so Its can handle extremely active traffic periods. Serverless computing does-not means there are no physical servers utilized, Of course there are servers, but we don't have to manage them, in background cloud provider manage( provisioning, scheduling, scaling, patching and more) for us, This gives developers more time to develop and optimize their front-end application code and business logic. And with serverless, customers never pay for idle capacity. They pay only for the resources required to run their applications, and only when those applications are running. Serverless is a polyglot environment, enabling developers to code in any language or framework - Java, Python, node.js - with which they're comfortable. Because serverless scales up and down on demand in response to workload, it offers significant cost savings for spiky workloads. But it does not offer the same savings for workloads characterized by predictable, steady or long-running processes; in these cases a traditional server environment might be simpler and more cost-effective. Serverless Implementations differ across service providers, and capabilities vary, including supported runtimes, authentication, scaling and monitoring. Serverless architectures are well-suited for event-driven, IOT and stream-processing workloads most notably open source Apache Kafka event streaming platform. Benefits: - Pay only for the time for our code will run. - Developer don't have to take care of servers or infrastructure, Its maintain by cloud provider, so they can focus more in development and business logic. - API Management & Integrated event sources. - Serverless scales up and down on demand in response to workload

SSL (Secure Socket Layer) allows information to travel from browser to server and back again using a secured transmission tunnel to combat eavesdropping. Veri?cation amount depends on the style of SSL certi?cate 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.
