NEW QUESTION 32
Which kind of scaling is supported by virtual machines in Oracle Cloud Infrastructure Compute service?
- A. Scaling up or down, and scaling in or out
- B. Only scaling in
- C. Only scaling out
- D. Only scaling up or down
Answer: A
Explanation:
Explanation
To change the shape of an OCI Instance
You can change the shape of a virtual machine (VM) instance without having to rebuild your instances or redeploy your applications. This lets you scale up your Compute resources for increased performance, or scale down to reduce cost.
Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
As load increases, instances are automatically provisioned: the instance pool scales out. As load decreases, instances are automatically removed: the instance pool scales in.
NEW QUESTION 33
What does compute instance horizontal scaling mean?
- A. adding additional compute instances
- B. changing compute instance size
- C. backing up data to object storage
- D. stopping/starting the instance
Answer: A

NEW QUESTION 47
You have a mission-critical application which requires to be globally available at all times.
Which deployment strategy should you adopt?
- A. Use multiple Fault Domains in any Availability Domain in multiple Regions.
- B. Use multiple Availability Domains In one Region.
- C. Use multiple Fault Domains In each Availability Domain in each Region.
- D. Use multiple Fault Domains In one Region.
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure is hosted in regions and availability domains. A region is a localized geographic area, and an availability domain is one or more data centers located within a region. A region is composed of one or more availability domains.
Regions are independent of other regions and can be separated by vast distances-across countries or even continents.
Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously.
Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
Fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains.
NEW QUESTION 48
Which statement is correct regarding the oracle cloud infrastructure Compute services?
- A. You cannot attach a block volume to a compute instance
- B. When you stop a compute instance, all data on the boot volume is lost
- C. You can attach a maximum of one public to each compute instance
- D. You can launch either virtual machines or bare metal instances
Answer: D
Explanation:
Explanation
Oracle Cloud Infrastructure offers both bare metal and virtual machine instances:
Bare Metal: A bare metal compute instance gives you dedicated physical server access for highest performance and strong isolation.
Virtual Machine: A virtual machine (VM) is an independent computing environment that runs on top of physical bare metal hardware. The virtualization makes it possible to run multiple VMs that are isolated from each other. VMs are ideal for running applications that do not require the performance and resources (CPU, memory, network bandwidth, storage) of an entire physical machine.
An Oracle Cloud Infrastructure VM compute instance runs on the same hardware as a bare metal instance, leveraging the same cloud-optimized hardware, firmware, software stack, and networking infrastructure.

___________________ is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud.
- A. Oracle Cloud Infrastructure Container Engine for Deployment
- B. Oracle Cloud Infrastructure Container Engine for Kubernetes
- C. Oracle Cloud Infrastructure Container Engine for Docker
- D. Oracle Cloud Infrastructure Container Engine for Containerization
Answer: B

Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.
You can access Container Engine for Kubernetes to define and create Kubernetes clusters using the Console and the REST API. You can access the clusters you create using the Kubernetes command line (kubectl), the Kubernetes Dashboard, and the Kubernetes API.
Container Engine for Kubernetes is integrated with Oracle Cloud Infrastructure Identity and Access Management (IAM), which provides easy authentication with native Oracle Cloud Infrastructure identity functionality.
