What is one of the benefits of a Private Cloud compared to Public Cloud?
- A. Costs less to bring up and get started
- B. Accessibility which is managed by the cloud provider
- C. Greater ability to customize infrastructure
- D. Easier to manage external data
Answer: C
Explanation:
Private cloud (also known as an internal cloud or corporate cloud) is a cloud computing environment in which all hardware and software resources are dedicated exclusively to, and accessible only by, a single customer. Private cloud combines many of the benefits of cloud computing-including elasticity, scalability, and ease of service delivery-with the access control, security, and resource customization of on-premises infrastructure. Advantages of private cloud include the following: Full control over hardware and software choices. Private cloud customers are free to purchase the hardware and software they prefer, vs. the hardware and software the cloud provider offers. Freedom to customize hardware and software in any way. Private cloud customers can customize servers in any way they want and can customize software as needed with add-ons or through custom development. Greater visibility into security and access control, because all workloads run behind the customers' own firewall. Fully enforced compliance with regulatory standards. Private cloud customers aren't forced to rely on the industry and regulatory compliance offered by the cloud service provider.
NEW QUESTION 74
A client want to secure virtual server instance (VSI) as soon as it is provisioned in Virtual Private Cloud (VPC) environment and control the traffice that passes through the VSI. Which option will accomplish this?
- A. Order transit gateway with the VSI
- B. Configure security groups before ordering the VSI
- C. Configure security groups after ordering the VSI
- D. Order a load balancer with the VSI
Answer: C
Explanation:
You can use security groups to enact a set of IP filter rules that define how to handle incoming and outgoing traffic to both the public and private interfaces your instance. Use security groups when you order a virtual server. That way, your server is protected when it is first provisioned. Other Scenarios with solutions listed below : 1. Security scenario: Customers want granular control over traffic at an instance level (apart from network-level firewalls). However, at the same time, the costs of a shared hardware firewall can add up quickly if you need to protect multiple servers in different data centers. Solution: You do not incur extra charges for using security groups. You can use security groups for all virtual servers that need protection in any of our global data centers. 2. Security scenario: You want to avoid configuring firewall rules on each server separately. Instead, you want an easily manageable firewall solution that spans servers in different global data centers. Solution: Define N security groups for N different types of servers in your cloud workload. Manage all rules for a security group in one place. Manage the security group associations with the virtual servers.

- A. IBM Cloud Direct Link Dedicated
- B. VPN Gateway
- C. IBM Cloud Direct Link Connect
- D. IBM Cloud Transit Gateway
Answer: D
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 79
What is true regarding SSL certificates to be used to encrypt traffice between IBM cloud and public network using SSL/TLS?
- A. SSL certificate can be managed through the IBM cloud console
- B. Bring Your Own Certificate should be managed by the SSL orders screen.
- C. Certificate must be ordered via IBM cloud
- D. IBM Cloud Processes the SSL certification details for management purposes.
Answer: A
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.
NEW QUESTION 80
Which statement is true about the Block Storage?
- A. Block Storage can be attached to compute instance
- B. Block Storage stores data in variable sized blocks
- C. Block Storage is only supported for Linux instances
- D. Block Storage is not durable
Answer: A
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.
When data is moved to block storage, the underlying SAN technology breaks the data into separate, uniform-sized pieces, or blocks. Each block will be given a unique identifier. The SAN will then place those blocks onto the physical storage, distributing them across several disks, often making multiple copies.
When a user or application requests data from a block storage system, the underlying SAN technology reassembles the data blocks and presents the data to the user or application.
Block storage decouples data from user environments. It allows data to be spread and duplicated across multiple storage devices, enabling faster retrieval and higher resilience to disk failures.
Benefits:
Provides the lowest latency: Block storage provides the lowest latency for network-based storage versus local disk drives in the server, Provide IOPS up to 48,000 IOPS.
High performing: Block storage is highly available and independent of the clients that access it. It remains available and durable regardless of client outages.
High redundancy: Network-based block storage is considered to have a higher level of redundancy compared to local disk storage.
Endurance and Performance tiers: Block storage has two tiers from which to choose. Volumes can be created from 20 GB to 12 TB in size.
Eight authorized hosts: Block storage allows eight authorized hosts (can request up to 64) to connect via the multipath IO (MPIO) iSCSI connection.
Snapshots: Block storage allows point-in-time non-disruptive "snapshots," which can be replicated to a cross-regional data center as a duplicate volume.
Custom costs: Block storage allows monthly and hourly billing cycles.
Data-at-rest encryption: Block storage offers provider-managed encryption-at-rest. Note: Customer-managed encryption is not supported by IBM Classic Storage; however, customer-managed encryption keys can be stored Use Cases:
As you have learned, block storage has a high performance and is easily updatable. Therefore, many organizations use it for transactional databases.
Because of its high performance and reliability, block storage is a common solution for storing emails. Block storage suitable for low latency workloads where consistently high speeds required.

When an IBM Cloud Satellite location is established, it allows the user to run selected IBM Cloud services in that location.
NEW QUESTION 83
What is a key feature of Virtual Private Cloud?
- A. To run an isolated environment within a public cloud
- B. Applications are automatically deployed across 3 zones
- C. Network traffic between VSIs on the private network
- D. It is deploy on-premises for increased security
Answer: A
Explanation:
Virtual Private Cloud used to run an isolated environment within a public cloud. A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. A VPC gives an enterprise the ability to define and control a virtual network that is logically isolated from all other public cloud tenants, creating a private, secure place on the public cloud. - VPC provides security in two ways. At the instance level protection is provided through security groups. At the subnet level, protection is provided by access control lists. Site-to-site virtual private networks (VPN) can be configured. A public gateway is used to enable egress to the internet for all virtual server instances on the attached subnet. - VPC provides flexibility when customers securely connect to on premises or remote infrastructure. VPCs can be created in various regions around the world. Customers can select a private IP address or bring their own IP address for cloud applications. Using Direct Link helps create a dedicated connection between the cloud and on premises resources. This allows an organization to extend its network and provide a consistent connection without using the public internet. - Responsiveness VPC makes it possible to create responsive cloud applications. Instance profiles with elasticity are used when creating applications for workloads, horizontal scaling, performance monitoring, and load balancing services.

NEW QUESTION 86
Which of the following are types of Application virtualization? (Select Three)
- A. Server-based application virtualization
- B. Local application virtualization
- C. Application streaming
- D. CPU visualization
- E. Server-defined networking (SDN) visualization
Answer: A,B,C
Explanation:
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.
