OCI leverages advanced encryption that leads to fast performance, OCI does not over subscribe CPU, but only memory, and OCI hypervisor provides industry leading performance are WRONG.
However, OCI does back claims with SLAs and offers predictable pricing for all services.
NEW QUESTION 46
What does compute instance horizonal scaling mean?
- A. backing up data to object storage
- B. adding additional compute instances
- C. changing compute instance size
- D. stopping/starting the instance
Answer: B
Explanation:
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.

NEW QUESTION 52
Which Oracle Cloud Infrastructure service allows you to run code without provisioning any underlying infrastructure resources?
- A. Oracle Functions
- B. Oracle Container Engine for Kubernetes
- C. Storage Gateway
- D. Compute service
Answer: A
Explanation:
Explanation
Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.
The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.
NEW QUESTION 53
Which two are enabled by Oracle Cloud Infrastructure Fault Domains?
- A. Build replicated systems for disaster recovery
- B. To mitigate the risk of large scale events such as earthquakes
- C. Protect against planned hardware maintenance
- D. To meet requirements for legal jurisdictions
- E. Protect against unexpected hardware or power supply failures
Answer: C,E
Explanation:
Explanation
A 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.
To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain.
Use fault domains to do the following things:
Protect against unexpected hardware failures or power supply failures.
Protect against planned outages because of Compute hardware maintenance.
We can use fault domains to do the following things:
1) Protect against unexpected hardware failures or power supply failures.
2) Protect against planned outages because of Compute hardware maintenance

NEW QUESTION 62
Which statement is correct regarding the oracle cloud infrastructure Compute services?
- A. You can attach a maximum of one public to each compute instance
- B. When you stop a compute instance, all data on the boot volume is lost
- C. You can launch either virtual machines or bare metal instances
- D. You cannot attach a block volume to a compute instance
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure Compute lets you provision and manage compute hosts, known as instances You can launch instances as needed to meet your compute and application requirements. After you launch an instance, you can access it securely from your computer, restart it, attach and detach volumes, and terminate it when you're done with it. Any changes made to the instance's local drives are lost when you terminate it. Any saved changes to volumes attached to the instance are retained.
Oracle Cloud Infrastructure offers both bare metal and virtual machine instances:
1) Bare Metal: A bare metal compute instance gives you dedicated physical server access for highest performance and strong isolation.
2) 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.

NEW QUESTION 64
Which service is the most effective for moving large amounts of data from your on-premises to OCI?
- A. Dynamic Routing Gateway
- B. Data Transfer appliance
- C. Data Safe
- D. Internal Gateway
Answer: B
NEW QUESTION 65
Which kind of scaling is supported by virtual machines in Oracle Cloud Infrastructure Compute service?
- A. Only scaling in
- B. Scaling up or down, and scaling in or out
- C. Only scaling out
- D. Only scaling up or down
Answer: B
Explanation:
Explanation
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 66

NEW QUESTION 68
Which capability can be used to protect against unexpected hardware or power supply failures within an availability domain?
- A. Top of Rack Switches
- B. Compartments
- C. Fault Domains
- D. Power Distribution Units
Answer: C
Explanation:
Explanation
A 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.
