Ans: You can create a new free cloud account. Or else you can go for Pay as you go option. To know more about the Pricing structure, Please check here
Q/A Related to the Service Model
Below are a few queries asked by our Trainees for this respective Topic
Q8. How maintenance (like backup etc) is getting handled in all cloud models.
Ans. Cloud Service Model: SaaS, PaaS, IaaS
- Infrastructure as a Service (IaaS): Infrastructure as a Service (IaaS) contains the basic building blocks for cloud IT and it provides access to networking features, compute (virtual or on dedicated hardware), and data storage space.
- Platform as a Service (PaaS): Platform as a Service (PaaS) removes the need for your organization to manage the underlying infrastructure (hardware and operating systems) and allows you to focus on the deployment and management of your applications.
- Software as a Service (SaaS): is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. In most cases, people referring to Software as a Service are referring to end-user applications.
For the PaaS & IaaS Service model, Backup is done by the customer (i.e You), its the customer responsibility to maintain Backups & for SaaS Model Backup is taken care by Oracle itself.
Note: To know more about Cloud Service Model, Check here
Q9. In the PaaS model, if the database is lost will Oracle take the responsibility to retrieve?
Ans. PaaS Model has two types of offerings, one is User managed & other is Autonomous Database
- For Autonomous Database, if data is lost because of cloud vendors (hardware failure highly unlikely) then Oracle will recover that, however, if the Data is deleted by mistake, or due to any human error, then its customer’s responsibility to restore.
- For User-Managed Database it is all the customer (yours) responsibility, only you need to maintain these.
Q/A: OCI (Gen2) vs OCI-C (Gen1)
Q10. Can you explain the difference between OCI Classic (OCI-C) and OCI?
Ans. OCI Classic is the old cloud offering which has older Generation Hardware & Storage, with this you can create Virtual Machine Instances
Whereas in OCI, the latest one, Oracle has offered NVME based flash Storage dedicated on the local server or network attached block volume. The Additional Service that comes in OCI is that you have Different types of Storage for Block Volume, you can choose, Standard, HIGH & DENSE.
More Importantly, you can go with OCI Bare Metal, you could go with just 52 OCPU’s in comparison to the fact that you had to take 250 OCPU’s in dedicated BareMetal in the classic cloud.
For the Other Storage Services concerned, it is more or less the same, you have Object Storage & Archive Storage in Both, these concepts remain the same even in OCI.
There are few things in OCI in terms of Service Offerings:
- Availability Domain: Availability Domain (AD) is one or more data centers located within a region. Your Data is protected within a region by means of using AD’s
- IAM(Identity & Access Management): In this, you will get the feature of Compartments.
- Audit Service
OCI Classic is a Generation 1 Cloud from Oracle whereas OCI is Generation 2 Cloud
Cloud At Customer (C@C) is based on OCI-C Model. To know more on OCI vs OCI-C, please check our blog
We have also Discussed Brief on Oracle Cloud at Customer (OCI-C)
We covered & discussed many Exam Dumps during the Live session. Check below one of Sample Quiz Question based on the above Slide
Note: If you know the answer for the above question, then leave a comment in the comment box below. Make sure you post the answer with the explanation why you think that it should be correct & others not.
Q/A: OCI Region, AD & FD
Then we covered about Region, Availability Domain (AD), Fault Domain (FD) in OCI.
Q11. What are the differences between Commercial vs Government Cloud?
Ans. There are two types of Cloud:
a) Government Cloud: Is dedicated to Government Organizations only (Federal compliant). Only government companies can access them with proper approvals, and this will be assigned by Oracle.
b) Commercial Cloud: Is not limited to one Organization but it is publicly available.
Q12. What is the importance of selecting the Region? Any Significance to choose?
Ans. Depending on in which region you want to keep your data, you select the appropriate Region
Q13. Can I change the Region in Tenancy?
Ans. Once a Service/Resource is created you can’t move that to another region but you can create new Service/Resource in another region by subscribing to that region. Check how to subscribe to another region here
Q14. Is it possible to assign two Regions in the same Tenancy?
Ans. As of 27th May 2019, There is a total of 7 Regions now (i.e. London Heathrow, Frankfurt, Ashburn, Phoenix, Canada, Tokyo, Seoul)
Yes, you subscribe to another region and create compute or database in different regions
Check for the Steps on how to subscribe to another region here
Q15. What is the point in setting the home Region when you can create resources in other Regions as well?
Ans. When you sign up for Oracle Free Trial Account, you will get home region by default and if you don’t change region at the time of resource creation then resources are created in that specific region.
Q16. I heard a latency issue if I am not selecting nearer one, what is that?
Ans. This is where edge service like DNS & Content Delivery Network (CDN) will comes handy.
Q17. If you are not subscribed to a Region, that means you cannot create Resources there?
Ans: Correct, your root user must go to Tenancy and subscribe to that region then the only non-admin user can create resources like compute, Network (VCN, Subnet, Route Table, etc) & Load Balancer in another region
- To know more on how to subscribe to a new region check here
Q18. Any additional charges in case we subscribe to another Region?
Ans: No charge for subscribing to another region but when you create Resource then it will be charged.
- Check Above questions for reference
Q19. How can users create Resources in another Region?
Ans: Users are global so you simply create a user and then admin user will subscribe to other regions, the localhost users can then create resources in other regions.
Q20. What would be the purpose of subscribing to another Region?
Ans: If you want to create a resource in a different region for failover to another region or you have users in another region too and they want to host their own application in that region then subscribing to another region fulfills all of the above needs.
Q21. Is any other interface to manage user, policy, group other than the console. In case we lost access to console temporarily?
Ans: Yes, as we can access the IAM with the help of Console, CLI & REST API. So, in case you lose access to console temporarily the other two methods i.e. CLI and REST API can be used to access the IAM components.
Availability Domain (AD)
Q22. How are costs distributed for 1 AD vs 3 AD, same for FD?
Ans. The cost will depend on the number of the machine running
If you have 1 machine in AD1 then you will charge for 1 machine & likewise, if you have 3 machines on all 3 AD’s & FD’s then it will charge for 3 machines.
Q23. Is there any distance define, how far will be one AD with another one?
Ans. Oracle doesn’t reveal the distance between 2 ADs but Predictable low latency & high speed encrypted interconnect between ADs
Q24. So basically AD is nothing but a Data Centre, correct?
Ans: Yes, you select AD when creating a compute or database.
Availability Domain represents a data centers located within a region. The Availability Domains within the same region are connected to each other by a low latency, high bandwidth network, which makes it possible for you to provide high-availability connectivity to the internet and on-premises, and to build replicated systems in multiple availability domains for both high-availability and disaster recovery.

Fault Domain (FD)
Q25. If I had created one server and it had gone one of the fault domain, and if any issue comes on that FD, then my server or compute will automatic failover to other FD or what?
Ans. No, it will not recover automatically. You’ll have to have a backup on another FD or AD.
We’ll cover this in the HA & DR module of our [1Z0-932] Oracle Cloud Infrastructure Architect Training
Q26. FD (Fault Domain) is logical or it is a Physical server?
Ans. A fault domain is a Physical Server which is a logical grouping of hardware and infrastructure within an Availability Domain, Provides a higher degree of protection from unexpected hardware failures or computer hardware maintenance.
Q27. Suppose I don’t want HA for my setup, and I want to put in one FD (Fault Domain), if Oracle wants to patch that FD and need a bounce, then Oracle need to take off my server right?
Ans. Yes, for scheduled maintenance on the server, Oracle will notify about the server not being available for the specified time. You must check all services after Server is back after maintenance.
We have discussed many Services in OCI including Database
Q28. Under Database, I can choose bare metal, VM and Exadata (1st option) in that option we have DB instance available for my prod and in that in case of any DB corruption and with help of gold policy backup. Will I able to retrieve the Database or Oracle will take care completely?
Ans. Under Bare Metal, Exadata & User Managed Services, you have to take backup & recovery, so in that case, you will have to take care of the backups & Recovery, Oracle will not take care of Backup & Recovery. We will cover this in detail in our Module 7.
Q29. What is CASB and how is it related to OCI?
Ans. CASB stands for Cloud Access Security Broker to alert any security violations. This is the security monitoring tool, you can secure OCI with the help of CASB.
CASB is part of our Cloud Security Course 1Z0-933 Certification
Q30. What do you mean by Cloud Marketplace?
Ans: From the marketplace you get pre-defined VMs / Compute images. We cover this topic in detail in our 1Z0-932 Training under Module 4 i.e Compute.
In our course, you will get the 1Z0-932 Certification Quiz question’s under every respective Module, that will help you to clear the 1Z0-932 certification.
