Which two resources reside exclusively in a single Oracle Cloud Infrastructure Availability Domain? (Choose two.)
Correct Answer: B,E
Question 17
Which of the following two tasks can be performed in the Oracle Cloud Infrastructure Console for Autonomous Data Warehouse?
Correct Answer: C,D
Explanation You can scale up/down your Autonomous Database to scale both in terms of compute (CPU) and storage only when needed, allows people to pay per use. Oracle allows you to scale compute and storage independently, no need to do it together. these scaling activities fully online (no downtime required) in Details page Autonomous Database in OCI console, click Scale Up/Down. Click on arrow to select a value for CPU Core Count or Storage (TB). Or Select auto scaling to allow the system to automatically use up to three times more CPU and IO resources to meet workload demand, compared to the database operating with auto scaling disabled.
Question 18
You need to transfer over 12 TB of data from on-premises to your cloud account. You started copying this data over the internet and noticed that it will take too long to complete. Without increasing the costs of your subscription, what is the recommended way to send this amount of data to your cloud account?
Correct Answer: A
Explanation References: Overview of Data Transfer ServiceOracle offers offline data transfer solutions that let you migrate data to Oracle Cloud Infrastructure. Moving data over the public internet is not always feasible due to high network costs, unreliable network connectivity, long transfer times, and security concerns. Our transfer solutions address these pain points, are easy to use, and provide significantly faster data upload compared to over-the-wire data transfer.https://docs.cloud.oracle.com/iaas/Content/DataTransfer/Concepts/overview.htm
Question 19
You are tasked with creating a highly available clustered application on Oracle Cloud Infrastructure consisting of three nodes. The round-trip latency between nodes must be less than 500 us (micro-seconds) and your cluster should be resilient to hardware failure. What is the recommended deployment strategy?
Correct Answer: D
Question 20
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?
Correct Answer: C
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.
