NEW QUESTION 48
What is a component of a virtual private cloud on IBM Cloud?

• A. Public gateway
• B. Objects
• C. Acess keys

Answer: A

Explanation:
A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. You can subdivide a VPC with subnets, where each subnet can reach the public internet through an optional public gateway. You can assign an FIP to any instance to reach it from the internet, or the other way around. This is independent of whether the subnet is attached to a public gateway. Subnets within IBM Cloud VPC offer private connectivity; they can talk to each other over a private link, through the implicit router. Setting up routes isn't necessary.

• A. VPN Gateway
• B. IBM Cloud Direct Link Connect
• C. IBM Cloud Transit Gateway
• D. IBM Cloud Direct Link Dedicated

Answer: C

Explanation:
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.

NEW QUESTION 57
What is virtualization?

• A. Allows a virtual machine to run on a physical host
• B. Seeing into the future
• C. Uses hardware to create an abstraction layer over software
• D. Allows multiple virtual machines to run on a single physical host

Answer: D

Explanation:
Virtualization is a process that allows for more efficient utilization of physical computer hardware and is the foundation of cloud computing. Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer-processors, memory, storage and more-to be divided into multiple virtual computers, commonly called virtual machines (VMs). Each VM runs its own operating system (OS) and behaves like an independent computer, even though it is running on just a portion of the actual underlying computer hardware. Benefit of virtualization: Virtualization brings several benefits to data center operators and service providers: Resource efficiency: Before virtualization, each application server required its own dedicated physical CPU-IT staff would purchase and configure a separate server for each application they wanted to run. (IT preferred one application and one operating system (OS) per computer for reliability reasons.) Invariably, each physical server would be underused. In contrast, server virtualization lets you run several applications-each on its own VM with its own OS-on a single physical computer (typically an x86 server) without sacrificing reliability. This enables maximum utilization of the physical hardware's computing capacity. Easier management: Replacing physical computers with software-defined VMs makes it easier to use and manage policies written in software. This allows you to create automated IT service management workflows. For example, automated deployment and configuration tools enable administrators to define collections of virtual machines and applications as services, in software templates. This means that they can install those services repeatedly and consistently without cumbersome, time-consuming. and error-prone manual setup. Admins can use virtualization security policies to mandate certain security configurations based on the role of the virtual machine. Policies can even increase resource efficiency by retiring unused virtual machines to save on space and computing power. Minimal downtime: OS and application crashes can cause downtime and disrupt user productivity. Admins can run multiple redundant virtual machines alongside each other and failover between them when problems arise. Running multiple redundant physical servers is more expensive. Faster provisioning: Buying, installing, and configuring hardware for each application is time-consuming. Provided that the hardware is already in place, provisioning virtual machines to run all your applications is significantly faster. You can even automate it using management software and build it into existing workflows. [Exam Tips]: You can expect few questions from Virtualization and benefits of virtualization.

NEW QUESTION 63
Block Storage LUNs can be provisioned from 20 GB to 12 TB with which 2 options?

• A. Distributed
• B. Redundant
• C. Performance
• D. Scalable
• E. Endurance

Answer: A,D

Explanation:
Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Both endurance and performance options provide a range of storage sizes, and the only difference between them is how the Input/Output Operations per Second (IOPS) is delivered for a given storage volume. - Endurance provides pre-set IOPS tiers of 0.25, 2, 4, and 10 IOPS/GB. - Performance allows the user to set a custom level of IOPS beyond 10 IOPS/GB. Under the virtual private cloud (VPC), block storage does not have endurance or performance tiers. Instead, users can set pre-defined or choose custom IOPS when provisioning the storage. Use Cases : Block storage suitable for low latency workloads where consistently high speeds required. Features : - Offer volume size from 20 GB to 12 TB, - Provide encryption for data at rest - Provide IOPS upto 48,000 IOPS - Highly available and resilient.

 

NEW QUESTION 64
Which is NOT a characteristic of the cloud defined by NIST?

• A. On-demand self-service
• B. Broad network access
• C. Resource pooling
• D. Rapid elasticity
• E. Self diagnosis

Answer: E

Explanation:
Correct Answers : The Essential Characteristics of Cloud Computing according to NIST : On-demand self-service : A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access : Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Resource pooling: The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, and network bandwidth. Rapid elasticity: Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. Measured service : Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. Self diagnosis: It's self made option, added for distraction.

 

NEW QUESTION 65
Which of the following are types of Key Value Database?(Select Two)

• A. etcd
• B. Redis
• C. MongoDB
• D. PostgreSQL

Answer: A,B

Explanation:
etcd is an open source distributed key-value store used to hold and manage the critical information that distributed systems need to keep running. etcd's performance is heavily dependent upon storage disk speed, so it's highly recommended to use SSDs in etcd environments. Redis (for REmote DIctionary Server) is an open-source, in-memory, NoSQL key-value store that is used primarily as an application cache or quick-response database. Redis supports multiple data structures, built-in Lua scripting, multiple levels of on-disk persistence, and high availability. Redis is an in-memory data store and can function as a database, cache, or message broker. In-Correct Answers : MongoDB is an open source, non-relational database management system that uses flexible documents to process and store various forms of data. A NoSQL solution, MongoDB provides an elastic data model that enables users to store and query multivariate data types with ease. This not only simplifies database management for developers but also creates a highly scalable environment for applications and services. MongoDB uses documents or collections of documents as its basic unit of data. Formatted as JSON objects, these documents can store various types of data and be distributed across multiple systems. MongoDB offers a few capabilities that make it stand out from other database management systems, including load balancing, ad hoc database queries, and multi-language support. PostgreSQL, commonly pronounced "Post-GRES," is an open-source database that has a strong reputation for its reliability, flexibility, and support of open technical standards. PostgreSQL provides the ability to restore databases to a specific moment in time because it maintains a write-ahead log that logs every database change. PostgreSQL features built-in support for multiple procedural languages.

What is true regarding SSL certificates to be used to encrypt traffice between IBM cloud and public network using SSL/TLS?

• A. IBM Cloud Processes the SSL certification details for management purposes.
• B. SSL certificate can be managed through the IBM cloud console
• C. Bring Your Own Certificate should be managed by the SSL orders screen.
• D. Certificate must be ordered via IBM cloud

Answer: B

Explanation:
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.
