NEW QUESTION 46
What purpose does an Oracle Cloud Infrastructure (OCI) Dynamic Routing Gateway Serve?
- A. Enables OCI Compute instances to be reached from internet
- B. Enables OCI Compute Instance to privately connect to OCI Object Storage
- C. Enable OCI Compute instances to connect to the internal
- D. Enables OCI Compute instance to connect to on-promises environments
Answer: D
Explanation:
Explanation
You can think of a Dynamic Routing Gateway (DRG) as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region.
For example, if you use an IPSec VPN or Oracle Cloud Infrastructure FastConnect (or both) to connect your on-premises network to your VCN, that private IPv4 address traffic goes through a DRG that you create and attach to your VCN. For scenarios for using a DRG to connect a VCN to your on-premises network, see Networking Scenarios. For important details about routing to your on-premises network, see Routing Details for Connections to Your On-Premises Network.
Also, if you decide to peer your VCN with a VCN in another region, your VCN's DRG routes traffic to the other VCN over a private backbone that connects the regions (without traffic traversing the internet). For information about connecting VCNs in different regions, see Remote VCN Peering (Across Regions).

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 55
Which option provides the best performance for running OLTP workloads in Oracle Cloud Infrastructure?
- A. OCI Dedicated Virtual Host
- B. OCI Virtual Machine Instance
- C. OCI Exadata DB Systems
- D. OCI Autonomous Data Warehouse
Answer: C
Explanation:
ExplanationOn an Exadata DB system, all databases share dedicated storage servers which include flash storage. By default, the databases are given equal priority with respect to these resources. The Exadata storage management software uses a first come, first served approach for query processing. If a database executes a major query that overloads I/O resources, overall system performance can be slowed down.
The I/O Resource Management (IORM) allows you to assign priorities to your databases to ensure critical queries are processed first when workloads exceed their resource allocations. You assign priorities by creating directives that specify the number of shares for each database. The number of shares corresponds to a percentage of resources given to that database when I/O resources are stressed.
Directives work together with an overall optimization objective you set for managing the resources. The following objectives are available:
1) Auto - Recommended. IORM determines the optimization objective and continuously and dynamically determines the optimal settings, based on the workloads observed, and resource plans enabled.
2) Balanced - For critical OLTP and DSS workloads. This setting balances low disk latency and high throughput. This setting limits disk utilization of large I/Os to a lesser extent than low latency to achieve a balance between good latency and good throughput.
3) High throughput - For critical DSS workloads that require high throughput.
4) Low latency - For critical OLTP workloads. This setting provides the lowest possible latency by significantly limiting disk utilization.

NEW QUESTION 62
Which Oracle Cloud Infrastructure (OCI) service is best suited for running serverless apps?
- A. Oracle Functions
- B. Audit
- C. Virtual Cloud Network
- D. Streaming
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.
Oracle Functions is based on Fn Project. Fn Project is an open source, container native, serverless platform that can be run anywhere - any cloud or on-premises. Fn Project is easy to use, extensible, and performant.
You can download and install the open source distribution of Fn Project, develop and test a function locally, and then use the same tooling to deploy that function to Oracle Functions.
You can access Oracle Functions using the Console, a CLI, and a REST API. You can invoke the functions you deploy to Oracle Functions using the CLI or by making signed HTTP requests.

What is a key benefit of Oracle Cloud Infrastructure (OCI) Virtual Machine DB Systems?
- A. No need to create database Indices
- B. Support for RAC DB systems
- C. Automated disaster recovery
- D. Automated backups to OCI Block Volume
Answer: B
Explanation:
Explanation
There are two types of DB systems on virtual machines:
* A 1-node virtual machine DB system consists of one virtual machine.
* A 2-node virtual machine DB system consists of two virtual machines. (RAC) A virtual machine DB system database uses Oracle Cloud Infrastructure block storage instead of local storage.
You specify a storage size when you launch the DB system, and you can scale up the storage as needed at any time.
For 1-node virtual machine DB systems, Oracle Cloud Infrastructure provides have a "fast provisioning" option that allows you to create your DB system using Logical Volume Manager as your storage management software.
Oracle Cloud Infrastructure offers single-node DB systems on either bare metal or virtual machines, and
2-node RAC DB systems on virtual machines. If you need to provision a DB system for development or testing purposes, then a special fast provisioning single-node virtual machine system is available.
You can manage these systems by using the Console, the API, the Oracle Cloud Infrastructure CLI, the Database CLI (DBCLI), Enterprise Manager, Enterprise Manager Express, or SQL Developer.
NEW QUESTION 67
What does compute instance vertical scaling mean?
- A. Changing to a large or smaller shape
- B. Providing Fault tolerance
- C. Adding additional compute instances
- D. Enabling Disaster recovery
Answer: A
Explanation:
Explanation
Changing the Shape of an Instance (Horizontal Scaling)
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 (vertical scaling)
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.
