QUESTION 2
You have an application that requires a shared file system. Which of the following services would you use?
A. File Storage
B. Archive Storage
C. Object Storage
D. Block Volume
Correct Answer: A
Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file
system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container
instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle
Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN). Large Compute
clusters of thousands of instances can use the File Storage service for high-performance shared storage. Storage
provisioning is fully managed and automatic as your use scales from a single byte to exabytes without upfront
provisioning. The File Storage service supports the Network File System version 3.0 (NFSv3) protocol. The service
supports the Network Lock Manager (NLM) protocol for file locking functionality. Oracle Cloud Infrastructure File Storage
employs 5-way replicated storage, located in different fault domains, to provide redundancy for resilient data protection.
Data is protected with erasure encoding. The File Storage service uses the “eventual overwrite” method of data
eradication. Files are created in the file system with a unique encryption key. When you delete a single file, its
associated encryption key is eradicated, making the file inaccessible. When you delete an entire file system, the file
system is marked as inaccessible. The service systematically traverses deleted files and file systems, frees all the used
space, and eradicates all residual files. Use the File Storage service when your application or workload includes big
data and analytics, media processing, or content management, and you require Portable Operating System Interface
(POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is
designed to meet the needs of applications and users that need an enterprise file system across a wide range of use
cases, including the following:

QUESTION 5
Which two security capabilities are offered by Oracle Cloud Infrastructure?
A. Always-on data encryption for data-at-rest.
B. Certificate Management service
C. Captcha
D. Key Management service
E. Managed Active Directory service
Correct Answer: AD
Oracle Cloud Infrastructure\\’s security approach is based on seven core pillars. Each pillar has multiple solutions
designed to maximize the security and compliance of the platform and to help customers to improve their security
posture. High Availability: Offer fault-independent data centers that enable high-availability scale-out architectures and
are resilient against network attacks, ensuring constant uptime in the face of disaster and security attacks. Customer
Isolation: Allow customers to deploy their application and data assets in an environment that commits full isolation from
other tenants and Oracle\\’s staff. Data Encryption: Protect customer data-at-rest and in-transit in a way that allows
customers to meet their security and compliance requirements with respect to cryptographic algorithms and key
management. Security Controls: Offer customers effectively and easy-to-use application, platform, and network security
solutions that allow them to protect their workloads, have a secure application delivery using a global edge network,
constrain access to their services, and segregate operational responsibilities to reduce the risk associated with
malicious and accidental user actions. Visibility: Offer customers comprehensive log data and security analytics that
they can use to audit and monitor actions on their resources, allowing them to meet their audit requirements and reduce
security and operational risk. Secure Hybrid Cloud: Enable customers to use their existing security assets, such as user
accounts and policies, as well as third-party security solutions when accessing their cloud resources and securing their
data and application assets in the cloud. Verifiably Secure Infrastructure: Follow rigorous processes and use effective
security controls in all phases of cloud service development and operation. Demonstrate adherence to Oracle\\’s strict
security standards through third-party audits, certifications, and attestations. Help customers demonstrate compliance
readiness to internal security and compliance teams, their customers, auditors, and regulators. Reference:

QUESTION 6
Which pricing model is NOT supported by Oracle Cloud Infrastructure?
A. Reserved Infrastructure
B. Universal Credits – Monthly Flex
C. Bring your own license
D. Pay-as-you-go
Correct Answer: A
The available purchase models are:
Pay As You Go (PAYG):
Billed in arrears based on consumption. Recommended for organizations who are trying new services, rapid
prototyping, or for elastic scaling.
Monthly Flex:
Billed in advance with a 12-month minimum. Use monthly or forfeit that month\\’s credits.
Recommended for customers with predictable production workloads or large long-running applications, such as HR,
payroll, analytics, and more.
Monthly Flex maximizes cost reduction with predictable monthly spending, similar to your monthly phone plan. Delivers
faster time to market by offering customers the choice of using any IaaS and PaaS services.
Oracle\\’s current PaaS offering is “license-included PaaS.” It includes:
1.
Compute and compute support
2.
Automation
3.
License entitlement and license support
Bring your own license
BYOL stands for “bring your own license.” Previously, you could bring your own licenses to Oracle IaaS, but to get the
benefits of PaaS automation, you couldn\\’t leverage existing licenses. This has been changed. We\\’re offering Oracle
BYOL
to PaaS, enabling our customers to leverage their investment in existing on-premises licenses in their journey to the
cloud.
Oracle BYOL to PaaS includes:
1.
Compute and compute support
2.
Automation
3.
Customers bring their on-premises license entitlement and get license support via their existing on-premises support
contract.
4.
As customers leverage their existing on-premises license entitlement, they can move to the cloud at a lower cost.
Reference: https://www.oracle.com/in/cloud/bring-your-own-license/faq/universal-credit-pricing.html OCI doesn\\’t offer
Reserved instances. Enterprise users and technology vendors alike require cost predictability to plan their budgets and run their business. The cost of running applications, databases, and large workloads in the cloud can be extremely
difficult to forecast leading to unforeseen expenses. Not with Oracle Cloud. Oracle has simple rate structures that
eliminate the cost surprises associated with hard-to-estimate usage elements like data egress and storage performance.
Oracle also charges the same rates for all regions, so going global on Oracle Cloud means no hidden cost variances.
Thus, Oracle\\’s cloud will provide you with industry-leading price-performance and tremendous business value.

QUESTION 10
Which capability can be used to protect against unexpected hardware or power supply failures within an availability
domain?
A. Fault Domains
B. Compartments
C. Top of Rack Switches
D. Power Distribution Units
Correct Answer: A
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.
Usually, 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.
