Question 16

You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?

A.Terminate the VM.Standard2.24 instance and do not preserve the boot volume
B.Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks
C.Terminate the VM.Standard2.24 instance and preserve the boot volume
D.Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes

Question 17

You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?

A.The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.
B.The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.
C.The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.
D.The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.

Question 18

Which two choices are true for Autonomous Data Warehouse (ADW)? (Choose two.)

A.Billing stops only when the ADW is terminated
B.Billing stops for both CPU usage and storage usage when ADW is stopped
C.Billing for compute stops when ADW is stopped
D.Billing for storage continues when ADW is stopped

Question 19

You deployed a web server in Oracle Cloud Infrastructure using an ephemeral public IP. After a few changes in your web server configuration, you rebooted the server and a new public IP was associated to your instance.
What should you do to prevent this from happening again?

A.Create a reserved public IP and associate it with the security list that your complete instance is using
B.Create a reserved public IP and associate it with the subnet of your compute instance
C.Create a reserved public IP and associate it with the VNIC of your compute instance
D.Create a reserved public IP and associate it with the hosts file of your web server

Correct Answer: C

Explanation
A public IP address is an IPv4 address that is reachable from the internet. If a resource in your tenancy needs to be directly reachable from the internet, it must have a public IP address. Depending on the type of resource, there might be other requirements.
There are two types of public IPs:
Ephemeral: Think of it as temporary and existing for the lifetime of the instance.
Reserved: Think of it as persistent and existing beyond the lifetime of the instance it's assigned to. You can unassign it and then reassign it to another instance whenever you like. Exception: reserved public IPs on public load balancers.
To create a new reserved public IP in your pool
Confirm you're viewing the region and compartment where you want to create the reserved public IP.
Open the navigation menu. Under Core Infrastructure, go to Networking and click Public IPs.
Click Create Reserved Public IP.
Enter the following:
Name: An optional friendly name for the reserved public IP. The name doesn't have to be unique, and you can change it later. Avoid entering confidential information.
Compartment: Leave as is.
Tags:Optionally, you can apply tags. If you have permissions to create a resource, you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure if you should apply tags, skip this option (you can apply tags later) or ask your administrator.
Click Create Reserved Public IP.
To assign a reserved public IP to a private IP
Prerequisite: The private IP must not have an ephemeral or reserved public IP already assigned to it. If it does, first delete the ephemeral public IP, or unassign the reserved public IP.
Confirm you're viewing the compartment that contains the instance with the private IP you're interested in.
Open the navigation menu. Under Core Infrastructure, go to Compute and click Instances.
Click the instance to view its details.
Under Resources, click Attached VNICs.
The primary VNIC and any secondary VNICs attached to the instance are displayed.
Click the VNIC you're interested in.
Under Resources, click IP Addresses.
The VNIC's primary private IP and any secondary private IPs are displayed.
For the private IP you're interested in, click the Actions icon (three dots), and then click Edit.
In the Public IP Address section, for Public IP Type, select the radio button for Reserved Public IP.
Enter the following:
Compartment: The compartment that contains the reserved public IP you want to assign.
Reserved Public IP: The reserved public IP you want to assign. You have three choices:
Create a new reserved public IP. You may optionally provide a friendly name for it. The name doesn't have to be unique, and you can change it later. Avoid entering confidential information.
Assign a reserved public IP that is currently unassigned.
Move a reserved public IP from another private IP.
Click Update.

Question 20

You are designing a networking infrastructure in multiple Oracle Cloud Infrastructure regions and require connectivity between workloads in each region. You have created a dynamic routing gateway (DRG) and a remote peering connection. However, your workloads are unable to communicate with each other.
What are two reasons for this? (Choose two.)

A.An internet gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the internet gateway
B.The route table associated with subnets in each VCN do not have a route rule defined to forward the traffic to their respective DRGs.
C.The security lists associated with subnets in each virtual cloud network (VCN) do not have the appropriate ingress rules.
D.Identity and Access Management (IAM) policies have not been defined to allow connectivity across the two VCNs in different regions.
E.A local peering gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the local peering gateway.
