1Z0-997-20 Exam Question 46

An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two

A.Enabling auto scaling does not change the concurrency and parallelism settings

B.Auto scaling also scales IO throughput linearly along with CPU

C.The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling

D.The maximum CPU cores that will be automatically allocated for this database is 16 CPUs

Your security team has informed you that there are a number of malicious requests for your web application coming from a set of IP addresses originating from a country in Europe.
Which of the following methods can be used to mitigate these type of unauthorized requests?

A.Deny rules in Virtual Cloud Network Security Lists for the specific set of IP addresses.

B.Web Application Firewall policy using access control rules

C.Delete Internet Gateway from Virtual Cloud Network.

D.Deny rules in Virtual Cloud Network Security Group for the specific set of IP addresses.

1Z0-997-20 Exam Question 48

You are currently working for a public health care company based in the United Stats. Their existing patient records runs in an on-premises data center and the customer is sending tape backups offsite as part of their recovery planning.
You have developed an alternative archival solution using Oracle Cloud Infrastructure (OCI) that will save the company a significant amount of mom on a yearly basis. The solution involves storing data in an OCI Object Storage bucket After reviewing your solution with the customer global Compliance (GRC) team they have highlighted the following security requirements:
* All data less than 1 year old must be accessible within 2 hour.
* All data must be retained for at least 10 years and be accessible within 48 hours
* AH data must be encrypted at rest
* No data may be transmitted across the public Internet
Which two options meet the requirements outlined by the customer GRC team?

A.Provision a FastConnect link to the closest OCI region and configure a private peering virtual circuit.

B.Create an OCI Object Storage Standard tier bucket Configure a lifecycle policy to archive any object that Is older than 365 days

C.Create a VPN connection between your on premises data center and OCI. Create a Virtual Cloud Network (VCN) along with an OCI Service Gateway for OCI Object Storage.

D.Provision a FastConnect link to the closest OCI region and configure a public peering virtual circuit

E.Create an OCI Object Storage Standard tier bucket. Configure a lifecycle policy to delete any object that is older than 7 years

Correct Answer: B,D

Explanation
The Oracle Services Network is a conceptual network in Oracle Cloud Infrastructure that is reserved for Oracle services. These services have public IP addresses that you typically reach over the internet. However, you can access the Oracle Services Network without the traffic going over the internet. There are different ways, depending on which of your hosts need the access:
Hosts in your on-premises network:
- Private access through a VCN with FastConnect private peering or VPN Connect: The on-premises hosts use private IP addresses and reach the Oracle Services Network by way of the VCN and the VCN's service gateway.
- Public access with FastConnect public peering: The on-premises hosts use public IP addresses.
regarding which Fastconnect Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet. With FastConnect, that traffic goes over your private physical connection.
so Answer 4 will be the best answer that meets the customer requirement A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT is required to reach those specific services. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.
Object Lifecycle Management lets you automatically manage the archiving and deletion of objects. By using Object Lifecycle Management to manage your Object Storage and Archive Storage data, you can reduce your storage costs and the amount of time you spend managing data.

1Z0-997-20 Exam Question 49

You work for a bank as the lead Oracle Cloud Infrastructure architect. You designed a highly scalable solution for your company's banking application. The architecture includes a load balancer, application servers with autoscaling configuration based on CPU utilization, and an Autonomous Database with Transaction Processing workload type running in a Virtual Cloud Network (VCN).
During the peak utilization period, the application users complain that the application runs slow.
What are two possible reasons for the application running slow at times? (Choose two.)

A.Instance pool in autoscaling configuration for the application servers did not scale out due to service limit breach of the VM shapes used by the application servers.

B.Instance pool in autoscaling configuration for the application servers did not scale out due to compartment quota breach of the VM shapes used by the application servers.

C.The VCN does not have a Network Security Group configured to allow traffic from the load balancer to all the application servers in the backend set.

D.Instance pool in autoscaling configuration for the Autonomous Database did not scale out due to misconfigured scaling policy.

E.The load balancer is not configured correctly to send traffic to all the listeners of the application servers in the backend set.

1Z0-997-20 Exam Question 50

As part of planning the network design on Oracle Cloud Infrastructure, you have been asked to create an Oracle Cloud Infrastructure Virtual Cloud Network (VCN) with 3 subnets, one in each Availability Domain. Each subnet needs to have a minimum of 64 usable IP addresses.
What is the smallest subnet and VCN size you should use to implement this design? The requirements are static, so no growth is expected.

A./22 for the VCN; /25 for the subnets

B./23 for the VCN; /25 for the subnets

C./24 for the VCN; /24 for the subnets

D.122 for the VCN; 124 for the subnets
