NHN Cloud Associate study plan

Map every NHN Cloud compute service (Instance, GPU Instance, Auto Scaling, Image, and Instance Template) to its console location and core purpose without consulting notes.

Provision a Linux Instance from scratch, including key pair creation, security group attachment, and block storage sizing, and record each decision in a build log.

Explain how Instance flavors (vCPU/memory ratios) and pricing models differ, and pick the right flavor for three stated workloads.

Describe the lifecycle of an Instance from creation through stop, termination, and deletion, noting which states still incur charges.

Configure an Auto Scaling group with a launch template, scaling policy, and health check, then trigger a scale-out event and capture the activity log.

Create a custom Image from a configured Instance and use it to launch a replacement Instance.

Compare NHN Cloud compute with at least one other public cloud you know, listing three terminology differences that could trip up an exam question.

Write down the default limits and quotas that apply to compute resources and how to request an increase.

Deploy a containerized application to NHN Cloud Container Registry and pull it from a Kubernetes cluster.

Create a Kubernetes cluster (or use NHN Kubernetes Service) and deploy a workload with a Service and an Ingress.

Explain the difference between a container registry, a managed Kubernetes service, and a serverless container option, and when to choose each.

Diagnose a failing pod using logs, events, and describe output, and document the fix.

Implement a rolling update and a rollback on your Kubernetes workload and record the revision history.

Configure horizontal pod autoscaling based on CPU and verify it scales under load.

Explain how container networking, service discovery, and load balancing interact in NHN Cloud.

Set up a private network for your cluster and confirm pods can reach an external endpoint through a NAT or egress path.

Build a VPC with public and private subnets, route tables, and an internet gateway, and prove traffic flows correctly from each subnet.

Configure security groups and network ACLs to allow only the intended ports, then verify blocked traffic is actually blocked.

Set up a load balancer in front of two instances and confirm health checks remove a failed node.

Explain floating IPs, NAT gateway behavior, and DNS resolution in NHN Cloud, and describe when each is required.

Create and attach block storage to an Instance, format and mount it, then detach and reattach it to confirm data persistence.

Configure object storage with a bucket, access policy, and lifecycle rule, and upload/download via both console and API.

Explain the trade-offs between block, file, and object storage, and choose the correct type for four given scenarios.

Set up a snapshot or backup schedule and restore from it to a fresh volume.

Provision a managed database instance, connect from an application in a private subnet, and confirm the security group path.

Perform a backup, restore to a new instance, and verify row counts match the source.

Explain read replicas, failover behavior, and maintenance windows, and describe how each affects application design.

Compare managed database offerings (relational vs. cache vs. search) and match each to a stated use case.

Complete two timed full-length practice sets and score at least 80% on each, reviewing every wrong answer.

Re-derive the five domains' key facts from memory using a blank sheet, then fill gaps from your notes.

Re-run one end-to-end scenario per domain in a single sitting to simulate exam-level recall under time pressure.

List your ten weakest facts and write a one-line mnemonic or rule for each.
