What is the difference between a tenancy and a compartment?
A tenancy is a unique customer account in Oracle Cloud Infrastructure. A compartment is a logical group of resources within a tenancy. Tenancies are isolated from each other, but compartments within a tenancy can share resources.
How do you design a VCN for a production environment?
To design a VCN for a production environment, you should consider the following factors:
Security: You should implement security best practices, such as using security lists and route tables to control traffic to and from resources in your VCN.
Performance:You should design your VCN to meet the performance requirements of your applications. This may involve using multiple availability domains and subnets.
Scalability: You should design your VCN to be scalable so that it can accommodate future growth.
What are the different network layers in OCI?
OCI supports the following network layers:
Default: The default network layer is the default network layer for VCNs.
Regional: The regional network layer provides a private network that spans all availability domains in a region.
Global: The global network layer provides a private network that spans all regions.
How do you configure a firewall in OCI?
To configure a firewall in OCI, you can use a security list or a network security group (NSG). Security lists are attached to subnets and NSGs are attached to resources.
To configure a security list, you create rules that specify which traffic is allowed to and from the subnet. To configure an NSG, you create rules that specify which traffic is allowed to and from the resource.
What are the different types of subnets in OCI?
OCI supports the following types of subnets:
Public: Public subnets are accessible from the public internet.
Private: Private subnets are not accessible from the public internet.
Regional: Regional subnets are available in all availability domains in a region.
Availability domain-specific: Availability domain-specific subnets are only available in a single availability domain.
What are the different storage options in OCI?
OCI offers the following storage options:
File Storage Service (FSS): FSS is a managed NFS file service that provides high-performance, scalable, and reliable file storage for applications.
Block Volume: Block Volume is a managed block storage service that provides persistent storage for compute instances.
Object Storage: Object Storage is a highly scalable and durable object storage service that can be used to store any type of data.
How do you choose the right storage option for a given workload?
To choose the right storage option for a given workload, you should consider the following factors:
Performance:
FSS is the best option for workloads that require high performance, such as database servers and application servers.
Block Volume is a good option for workloads that require persistent storage, such as compute instances and file servers. Object Storage is a good option for workloads that require highly scalable and durable storage, such as backups and archives.
Cost:
FSS is the most expensive storage option, followed by Block Volume and Object Storage.
Features:
FSS offers a variety of features, such as snapshots, clones, and backups.
Block Volume offers snapshots and backups.
Object Storage offers lifecycle management and versioning.
What is FSS and how do you use it?
FSS is a managed NFS file service that provides high-performance, scalable, and reliable file storage for applications. To use FSS, you create a file system and then mount it on your compute instances.
What is Block Volume and how do you use it?
Block Volume is a managed block storage service that provides persistent storage for compute instances. To use Block Volume, you create a volume and then attach it to your compute instance.
What is Object Storage and how do you use it?
Object Storage is a highly scalable and durable object storage service that can be used to store any type of data. To use Object Storage, you create a bucket and then upload objects to the bucket.
What are some best practices for OCI administration?
Here are some best practices for OCI administration:
Implement security best practices:
You should implement security best practices, such as using security lists and route tables to control traffic to and from resources in your VCN. You should also use strong passwords and enable two-factor authentication for all users.
Monitor your resources:
You should monitor your resources to ensure that they are performing
