Oracle Cloud Infrastructure 2022 Foundations Associate Sample Questions (Q129-Q134):

NEW QUESTION # 129
What does compute instance horizonal scaling mean?

• A. backing up data to object storage
• B. stopping/starting the instance
• C. changing compute instance size
• D. adding additional compute instances

Answer: D Explanation:
Cloud Horizontal Scaling refers to provisioning additional servers to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean adding additional instances instead of moving to a larger instance size.
Cloud Vertical Scaling refers to adding more CPU or memory to an existing server, or replacing one server with a more powerful server.
Reference:
https://cloudcheckr.com/cloud-cost-management/cloud-vs-data-center-what-is-scalability-in-cloud-computing/ Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.

With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool - Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.
NEW QUESTION # 130

NEW QUESTION # 131
A customer wants to deploy a customized e commerce Web application using multiple virtual machines, block storage, databases, load balancer and web application firewall.
What cloud model can be used to host this application?

• A. Anything as a Service (XaaS)
• B. Infrastructure as a Service (IaaS)
• C. Software as a Service (SaaS)
• D. Platform as a Service (PaaS)

Answer: B Explanation:
https://www.oracle.com/cloud/what-is-iaas/
What Is IaaS?
Infrastructure as a service (IaaS) is a type of cloud service model in which computing resources are hosted in the cloud. Businesses can use the IaaS model to shift some or all of their use of on-premises or colocated data center infrastructure to the cloud, where it is owned and managed by a cloud provider. These infrastructure elements can include compute, network, and storage hardware as well as other components and software.
In the IaaS model, the cloud provider owns and operates the hardware and software and also owns or leases the data center. When you have an IaaS solution, you rent the resources like compute or storage, provision them when needed, and pay for the resources your organization consumes. For some resources such as compute, you'll pay for the resources you use. For others such as storage, you'll pay for capacity.
How Does IaaS Work?
In a typical IaaS model, a business-which can be of any size-consumes services like compute, storage, and databases from a cloud provider. The cloud provider offers those services by hosting hardware and software in the cloud. The business will no longer need to purchase and manage its own equipment, or space to host the equipment, and the cost will shift to a pay-as-you-go model. When the business needs less, it pays for less. And when it grows, it can provision additional computing resources and other technologies in minutes.
In contrast, in a traditional on-premises scenario, a business manages and maintains its own data center. The business must invest in servers, storage, software, and other technologies, and hire an IT staff or contractors to purchase, manage, and upgrade all the equipment and licenses. The data center has to be built to meet peak demand, even though sometimes workloads decline and those resources stand idle. Conversely, if the business grows quickly, the IT department might struggle to keep up.
NEW QUESTION # 132
What two statements regarding the Virtual Cloud Network (VCN) are true?

• A. VCN is a regional resource that span across all the Availability Domains in a Region.
• B. A single VCN can contain both private and public Subnets.
• C. You can only create one VCN per region.
• D. VCN is a global resource that span across all the Regions
• E. The VCN is the IPSec-based connection with a remote on premises location.

Answer: A,B Explanation:
When you work with Oracle Cloud Infrastructure, one of the first steps is to set up a virtual cloud network (VCN) for your cloud resources.
VIRTUAL CLOUD NETWORK (VCN) :
A virtual, private network that you set up in Oracle data centers. It closely resembles a traditional network, with firewall rules and specific types of communication gateways that you can choose to use. A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice. See Allowed VCN Size and Address Ranges. The terms virtual cloud network, VCN, and cloud network are used interchangeably in this documentation. For more information, see VCNs and Subnets.
SUBNETS :
Subdivisions you define in a VCN (for example, 10.0.0.0/24 and 10.0.1.0/24). Subnets contain virtual network interface cards (VNICs), which attach to instances. Each subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. You can designate a subnet to exist either in a single availability domainavailability domain or across an entire region (regional subnets are recommended). Subnets act as a unit of configuration within the VCN: All VNICs in a given subnet use the same route table, security lists, and DHCP options (see the definitions that follow). You can designate a subnet as either public or private when you create it. Private means VNICs in the subnet can't have public IP addresses. Public means VNICs in the subnet can have public IP addresses at your discretion. See Access to the Internet.
NEW QUESTION # 133

Answer: D,E
NEW QUESTION # 134
...... It is well known that Oracle certification plays a big part in the IT field and obtaining it means you have access to the big companies and recognized by the authority. But the reality is that the 1z0-1085-22 Braindumps torrents are very difficult and the pass rate of 1z0-1085-22 practice test is low. So choosing our exam training materials are very necessary to every candidate. 1z0-1085-22 New Braindumps: https://www.actualtestpdf.com/Oracle/1z0-1085-22-practice-exam-dumps.html
