- A. Dynamic Routing Gateway
- B. Internet Gateway
- C. Data Transfer appliance
- D. Data Safe
Answer: C
Explanation:
Explanation
APPLIANCE-BASED DATA TRANSFER
You send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.
This solution supports data transfer when you are migrating a large volume of data and when using disks is not a practical alternative. You do not need to write any code or purchase any hardware. Oracle supplies the transfer appliance and software required to manage the transfer.
https://docs.cloud.oracle.com/en-us/iaas/Content/DataTransfer/Concepts/overview.htm Oracle Cloud Infrastructure Data Transfer Appliance securely moves terabytes or petabytes data between on-premise data centers and the cloud. The service reduces data migration times from weeks or months to just hours and is available for data import to the cloud and data export from the cloud.

Explanation
When you create an instance, the instance is automatically attached to a virtual network interface card (VNIC) in the cloud network's subnet and given a private IP address from the subnet's CIDR. You can let the IP address be automatically assigned, or you can specify a particular address of your choice. The private IP address lets instances within the cloud network communicate with each other.
NEW QUESTION 61
A customer wants to use Oracle Cloud Infrastructure (OCI) storing application backups which can be stored for months, but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement?
- A. Object Storage (standard)
- B. File Storage
- C. Block Volume
- D. Archive Storage
Answer: A
Explanation:
Explanation
Oracle Cloud Infrastructure offers two distinct storage class tiers to address the need for both performant, frequently accessed "hot" storage, and less frequently accessed "cold" storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible.
Use Object Storage for data to which you need fast, immediate, and frequent access. Data accessibility and performance justifies a higher price to store data in the Object Storage tier.
Use Archive Storage for data to which you seldom or rarely access, but that must be retained and preserved for long periods of time. The cost efficiency of the Archive Storage tier offsets the long lead time required to access the data.
Unlike Object Storage, Archive Storage data retrieval is not instantaneous.

Answer: A,C,F
Explanation:
Explanation
DATA ENCRYPTION
Protect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements for cryptographic algorithms and key management The Oracle Cloud Infrastructure Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption.
By default all volumes and their backups are encrypted using the Oracle-provided encryption keys. Each time a volume is cloned or restored from a backup the volume is assigned a new unique encryption key.
The File Storage service encrypts all file system and snapshot data at rest. By default all file systems are encrypted using Oracle-managed encryption keys. You have the option to encrypt all of your file systems using the keys that you own and manage using the Vault service.
Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own data encryption key. Data encryption keys are always encrypted with a master encryption key that is assigned to the bucket. Encryption is enabled by default and cannot be turned off. By default, Oracle manages the master encryption key.

NEW QUESTION 67
Your company has deployed a business critical application in Oracle Cloud Infrastructure. What should you do to ensure that your application has the highest level of resilience and availability?
- A. Deploy the application across multiple Availability Domains and Subnets
- B. Deploy the application across multiple Regions and Availability Domains
- C. Deploy the application across multiple Virtual Cloud Networks
- D. Deploy the application across multiple Availability Domains and Fault Domains
Answer: B
Explanation:
Explanation
To design a high availability architecture, three key elements should be considered- redundancy, monitoring, and failover:
1) Redundancy means that multiple components can perform the same task. The problem of a single point of failure is eliminated because redundant components can take over a task performed by a component that has failed.
2) Monitoring means checking whether or not a component is working properly.
3) Failover is the process by which a secondary component becomes primary when the primary component fails.
The best practices introduced here focus on these three key elements. Although high availability can be achieved at many different levels, including the application level and the cloud infrastructure level, here we will focus on the cloud infrastructure level.
An Oracle Cloud Infrastructure region is a localized geographic area composed of one or more availability domains, each composed of three fault domains. High availability is ensured by a redundancy of fault domains within the availability domains.
An availability domain is one or more data centers located within a region. Availability domains are isolated from each other, fault tolerant, and unlikely to fail simultaneously. Because availability domains do not share physical infrastructure, such as power or cooling, or the internal availability domain network, a failure that impacts one availability domain is unlikely to impact the availability of others.
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. As a result, an unexpected hardware failure or a Compute hardware maintenance that affects one fault domain does not affect instances in other fault domains.
You can optionally specify the fault domain for a new instance at launch time, or you can let the system select one for you.
All the availability domains in a region are connected to each other by a low-latency, high bandwidth network.
This predictable, encrypted interconnection between availability domains provides the building blocks for both high availability and disaster recovery.
NEW QUESTION 68

What cloud model can be used to host this application?
- A. Platform as a Service (PaaS)
- B. Software as a Service (SaaS)
- C. Anything as a Service (XaaS)
- D. Infrastructure as a Service (IaaS)
Answer: B
NEW QUESTION 69
Which Oracle cloud infrastructure capability can be used to protect against power failures within an availability Domain?
- A. Top of Rack Switch
- B. Services Cells
- C. Fault Domains
- D. Data Plane
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.
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.
NEW QUESTION 70
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.
