Which two statements are true about private IP objects? Each instance receives a primary private IP object and a secondary private IP object at launch. Secondary private IPs must be manually deleted when you terminate the mapped instance. You can add a secondary private IP to either the primary VNIC or a secondary VNIC of an instance after it's launched. A private IP can have a public IP assigned to it.
When changing the performance level of boot volumes, which two performance levels can you select? Lower cost Balanced High performance Ultra-high performance.
You want to make a point-in-time snapshot of the data on a block volume. Under which condition can you make a block volume backup? When it is attached to an instance or while it is detached OCI does not provide point-in-time backup of data on a block volume. Only when it is detached from all instances Only when it is attached to an instance.
When you create a block volume, what is its default performance level? Balanced Ultra-high performance Lower cost High performance.
What happens to traffic if there is no route rule that matches the network traffic you intend to route outside the VCN? It is sent over the NAT gateway. It is sent over the Internet gateway. It is sent over FastConnect. It is dropped. .

Which two statements are true? Object Y can be modified or deleted immediately. Object Y cannot be modified or deleted for the next 9 months. Object X cannot be modified or deleted for the next 2 months. Object X can be modified or deleted immediately. .
Which two conditions must be met for an instance to communicate directly with the Internet? Instance must be in a private subnet. Public subnet must have route tables without any security lists. Instance must have a public IP address. Instance's VCN must have an Internet gateway. .

You require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. Which storage service must you use? File Storage Vault Storage Object Storage Block Storage.
Which two statements are true about the OS Management service? If the OS Management service fails while updating a package, you must contact Oracle Support to identify the cause of failure. Actions such as installing or removing updates are synchronous and do not initiate work requests. It allows you to specify a date and time when a managed instance will be updated If a managed instance is terminated, the OS Management service will automatically remove it from the managed instance list.
An instance running in a development compartment needs to make API calls to other OCI services. How can you achieve this without configuring user credentials or setting up a configuration file? Create a dynamic group with matching rules to include your instance and write a policy for this dynamic group. Create a dynamic group with matching rules to include your instance. The requirement cannot be achieved by configuring user credentials or setting up a configuration file. Instances can automatically make calls to other OCI services; hence, no configuration is needed.
Which two statements are true about local VCN peering? It uses an Internet gateway. The two VCNs must have overlapping CIDRs. The VCNs can be in different Oracle Cloud Infrastructure tenancies but in the same region. You can use a single DRG for local peering. .

You cannot use multiple site-to-site connections between your on-premises network and virtual cloud network (VCN). It encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives. It provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). .
