NEW QUESTION # 53
What is the primary goal for distributing resources across multiple Availability Domains in Oracle Cloud Infrastructure?
- A. To increase storage capability for a region
- B. To improve fault tolerance and high availability
- C. To segregate resources based on project or department
- D. To reduce latency for uses in different geographic locations
Answer: B
Explanation:
The primary goal for distributing resources across multiple availability domains in Oracle Cloud Infrastructure is to improve fault tolerance and high availability. An availability domain is one or more data centers located within a region that have fault-tolerant power and network connectivity. Availability domains are isolated from each other within a region, which provides protection from failures that affect multiple data centers at once. By distributing resources across multiple availability domains, users can ensure that their applications can continue to run even if one availability domain becomes unavailable.
NEW QUESTION # 54
You have a web application that receives 5X more traffic on the weekends than weekdays. You need to automatically match capacity to demand, while keeping the application up and running, and also saving cost.
Which Oracle Cloud Infrastructure (OCI) compute feature can be used to meet these requirements?
- A. Parallel Scaling
- B. Vertical Scaling
- C. Autoscaling
- D. Manual Scaling
Answer: C
Explanation:
Autoscaling is an Oracle Cloud Infrastructure (OCI) compute feature that automatically adjusts the number of compute instances in an instance pool based on performance metrics such as CPU utilization. Autoscaling can help you match capacity to demand, while keeping the application up and running, and also saving cost. You can configure autoscaling policies to scale up or down the instance pool based on predefined thresholds or schedules
NEW QUESTION # 55
What does compute instance vertical scaling mean?
- A. Adding additional compute instances
- B. Changing to a large or smaller shape
- C. Providing Fault tolerance
- D. Enabling Disaster recovery
Answer: B
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.

A compartment quota can specify the maximum number of resources, the allowed shapes and sizes, and the minimum performance levels for resources within a compartment.
NEW QUESTION # 59
Which TWO Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) firewall features can be used for controlling traffic?
(Choose all correct answers}
- A. Network Security Groups
- B. VCN Flow Logs
- C. Security Lists
- D. VNIC Metrics
- E. Network visualizer
Answer: A,C
Explanation:
Network Security Groups (NSGs) and Security Lists (SLs) are two virtual firewall features that can be used for controlling traffic in an OCI Virtual Cloud Network (VCN). NSGs and SLs allow you to create stateful network filtering rules that allow or deny network traffic based on source and destination IP addresses, ports, and protocols5 NSGs are a subsequent feature designed for application components that have different security postures. NSGs are a set of security rules that you can apply to a set of VNICs in a VCN. NSGs are associated with VNICs, not subnets. You can use NSGs to implement a network security policy at the level of individual VNICs or a group of VNICs. For example, you can use NSGs to control traffic between tiers of an application deployed in a VCN5 SLs are the original virtual firewall feature from the Networking service. SLs are a set of security rules that you apply to a subnet in a VCN. SLs are associated with subnets, not VNICs. You can use SLs to implement a network security policy at the level of the subnet. For example, you can use SLs to control traffic between subnets in a VCN5

NEW QUESTION # 65
You have a mission-critical application which requires to be globally available at all times.
Which deployment strategy should you adopt?
- A. Use multiple Availability Domains In one Region.
- B. Use multiple Fault Domains In one Region.
- C. Use multiple Fault Domains in any Availability Domain in multiple Regions.
- D. Use multiple Fault Domains In each Availability Domain in each Region.
Answer: D
Explanation:
Oracle Cloud Infrastructure is hosted in regions and availability domains. A region is a localized geographic area, and an availability domain is one or more data centers located within a region. A region is composed of one or more availability domains.
Regions are independent of other regions and can be separated by vast distances-across countries or even continents.
Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
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.

NEW QUESTION # 66
Which is a key benefit of using oracle cloud infrastructure autonomous data warehouse?
- A. Scale both CPU and Storage without downtime
- B. Apply database patches as they become available
- C. No username and password required
- D. Maintain root level acress to the underlying operating system
Answer: A
Explanation:
Oracle Autonomous Data Warehouse is a cloud data warehouse service that eliminates virtually all the complexities of operating a data warehouse and securing data. It automates provisioning, configuring, securing, tuning, scaling, patching, backing up, and repairing of the data warehouse. Unlike other "fully managed" cloud data warehouse solutions that only patch and update the service, it also features elastic, automated scaling, performance tuning, security, and a broad set of built-in capabilities that enable machine learning analysis, simple data loading, and data visualizations.
Data Warehouse uses continuous query optimization, table indexing, data summaries, and auto-tuning to ensure consistent high performance even as data volume and number of users grows. Autonomous scaling can temporarily increase compute and I/O by a factor of three to maintain performance. Unlike other cloud services which require downtime to scale, Autonomous Data Warehouse scales while the service continues to run.
