Which two statements are true about Oracle Cloud Infrastructure Compute Service? (Choose two.)
Which two statements are true about Oracle Cloud Infrastructure Compute Service? (Choose two.)
Oracle Cloud Infrastructure Compute Service allows you to launch both virtual and bare metal instances using the same LaunchInstance API. Additionally, you can share custom images across tenancies and regions using the image import/export functionality. Therefore, the correct statements are that you can launch a virtual or bare metal instance using the same LaunchInstance API and you can share custom images across tenancies and regions.
Which five are the required parameters to launch an instance in Oracle Cloud Infrastructure? (Choose five)
To launch an instance in Oracle Cloud Infrastructure, five required parameters must be specified. These are: subnet, Availability Domain, Virtual Cloud Network, instance shape, and image operating system. These parameters are essential to define the network environment, resource allocation, and the software to be used for the instance. Host name and private IP address are not mandatory as defaults can be assigned during instance creation.
Which DNS resource record type is used to point a host name to an IPv4 address?
The DNS resource record type used to point a host name to an IPv4 address is the 'A' record. The 'A' record maps a domain name to its corresponding IPv4 address, allowing the domain name to be translated into the IP address necessary for routing the data packets over the internet.
Which three can you achieve by using Terraform? (Choose three.)
Terraform is capable of creating resources in the right order without regard to the order in the Terraform plan file, as it automatically determines dependencies. It can also automatically re-provision resources that are tainted or whose configuration has changed. Additionally, Terraform can generate a plan after translating a deployed infrastructure to ensure what changes would be made on the next apply. It does not automatically destroy all resources in tenancy or continuously maintain configuration files in instances.
Your application front end consists of several Oracle Cloud Infrastructure compute instances behind a load balancer. You have configured the load balancer to perform health checks on these instances.
What will happen if an instance fails to pass the configured health checks?
When an instance fails to pass the configured health checks, the load balancer will stop sending traffic to that instance. This ensures that only healthy instances receive traffic, thereby providing high availability and reliability to the application. The load balancer does not automatically replace, terminate, or permanently remove the instance from the backend set; it simply stops sending traffic to it until it passes the health checks again.
