1NHN Cloud organizes its infrastructure into Regions and Availability Zones. What is the primary purpose of deploying resources across multiple Availability Zones in the same Region?

A.To reduce inter-region data transfer costs

B.To achieve fault isolation so that a failure in one zone does not affect resources in another

C.To increase the total number of IP addresses available to a project

D.To allow resources to share the same private network without VPC peering

Explanation: Availability Zones are physically separated data center facilities within a Region with independent power, cooling, and networking. Spreading resources across AZs ensures that a hardware or facility failure in one zone does not impact workloads running in another, providing high availability. Data transfer costs and IP address pools are separate concerns, and AZs do not eliminate the need for VPC configuration.

2Which NHN Cloud service lets you create and manage virtual servers (virtual machines) in the cloud?

A.NHN Kubernetes Service (NKS)

B.Object Storage

C.Instance

D.RDS for MySQL

Explanation: The NHN Cloud Instance service (under the Compute category) provides virtual machine creation and management. NKS is a managed Kubernetes container service, Object Storage provides S3-compatible blob storage, and RDS for MySQL is a managed relational database service.

3When creating an NHN Cloud Instance, which component defines the allowed inbound and outbound traffic rules at the virtual machine level?

A.Network ACL

B.Security Group

C.Route Table

D.Floating IP

Explanation: Security Groups in NHN Cloud act as virtual firewalls attached to instances, controlling allowed inbound and outbound traffic by protocol, port range, and source/destination CIDR. Route Tables control traffic routing within subnets. Floating IPs provide external IP addresses. Network ACLs operate at the subnet level in some cloud providers but are distinct from Security Groups.

4An NHN Cloud Instance needs to communicate with the public internet but currently only has a private IP. Which networking resource do you assign to enable outbound and inbound public internet access for that specific instance?

A.Network ACL rule allowing port 80

B.VPC peering connection to the default VPC

C.Floating IP

D.Internet Gateway attachment on the subnet

Explanation: A Floating IP is a public IP address that can be associated with a specific NHN Cloud Instance, enabling direct inbound and outbound internet communication. Without a Floating IP the instance is reachable only within the VPC. Route Tables, ACLs, and VPC peering do not by themselves provide public internet connectivity to an individual instance.

5NHN Cloud's Virtual Private Cloud (VPC) allows you to create an isolated network. What is the maximum number of VPCs you can create per project in the default resource policy?

A.1

B.3

C.5

D.10

Explanation: NHN Cloud's default resource policy allows up to 3 VPCs per project (per region). If additional VPCs are needed, a service limit increase can be requested through NHN Cloud support. Understanding default quotas is important for designing architectures that stay within the default limits or plan quota increases.

6You deploy multiple Instances across different subnets in a VPC and want to distribute HTTP(S) traffic evenly among them. Which NHN Cloud service should you use?

A.Floating IP

B.Load Balancer

C.NAT Gateway

D.VPN Gateway

Explanation: NHN Cloud's Load Balancer service distributes incoming network traffic across multiple backend instances using configurable listeners and algorithms such as round-robin. A Floating IP maps to a single instance. NAT Gateway provides outbound internet access for private instances. VPN Gateway connects on-premises networks to the VPC.

7NHN Cloud Load Balancer supports two main routing modes. Which option correctly describes Layer 7 (L7) routing in the NHN Cloud Load Balancer?

A.Routes traffic based purely on IP address and TCP port

B.Routes traffic based on HTTP host headers, URL paths, or other application-layer attributes

C.Encrypts all traffic between the load balancer and backend instances using IPSec

D.Provides DNS-based traffic distribution across multiple Regions

Explanation: Layer 7 routing in NHN Cloud Load Balancer operates at the application layer, allowing rules based on HTTP host headers, URL paths, and similar application attributes. Layer 4 routing uses IP and TCP/UDP port information only. IPSec encryption is a separate feature, and DNS-based global load balancing is a different service.

8Which NHN Cloud storage service is an S3-compatible object storage designed for storing large volumes of unstructured data such as images, videos, and backups?

A.Block Storage

B.NAS (Network Attached Storage)

C.Object Storage

D.Instance local disk

Explanation: NHN Cloud Object Storage is an S3-compatible service for storing and retrieving unstructured data objects such as images, videos, logs, and backups at scale. Block Storage provides persistent block-level volumes attached to instances. NAS provides file-system-level shared network storage. Instance local disk is ephemeral storage directly on the physical host.

9A developer wants to access NHN Cloud Object Storage directly from application code using the AWS S3 SDK. What endpoint compatibility feature makes this possible?

A.NHN Cloud Object Storage supports only the proprietary NHN API

B.NHN Cloud Object Storage is compatible with the AWS S3 API, enabling AWS SDK usage with a custom endpoint

C.NHN Cloud Object Storage uses FTP for programmatic access

D.Object Storage can only be accessed through the NHN Cloud console

Explanation: NHN Cloud Object Storage is S3-compatible, meaning it exposes an API interface compatible with Amazon S3. Applications written with the AWS SDK can connect to NHN Cloud Object Storage by specifying the NHN Cloud Object Storage endpoint URL. This lowers migration effort and allows reuse of existing S3 tooling.

10NHN Cloud Block Storage provides persistent storage volumes. What happens to data stored on a Block Storage volume when the associated Instance is terminated?

A.Data is automatically replicated to Object Storage for archival

B.The volume is deleted together with the instance by default

C.The volume persists independently and can be reattached to a new instance

D.Data is permanently erased immediately upon instance stop

Explanation: NHN Cloud Block Storage volumes are persistent and exist independently of the instance lifecycle. When an instance is terminated, the attached Block Storage volume continues to exist and can be reattached to another instance. This is different from the instance's local (ephemeral) disk, which is lost when the instance is deleted.

NHN Cloud Associate Study Tips from Top Performers

1Master the VPC networking model: VPCs contain Subnets per AZ, Floating IPs attach to individual instances for public access, NAT Gateway enables private instances to reach the internet outbound, and VPC Peering is non-transitive

2Understand the difference between Object Storage (S3/Swift-compatible, pay-per-use, S3 lifecycle) and Block Storage (provisioned volume, exclusive to one instance, snapshotable) and NAS (NFS shared file system for multi-instance concurrent access)

3Know NHN Cloud's IAM structure: Organization contains Projects; NHN Cloud members use NHN Cloud accounts; IAM members are organization-managed; Infrastructure ADMIN controls compute/network/storage; Project ADMIN manages members and services

4Practice NKS cluster operations: creating a cluster requires Infrastructure ADMIN or NKS ADMIN role; download kubeconfig to use kubectl; LoadBalancer Service type auto-provisions an NHN Cloud Load Balancer; PVCs provision Block Storage volumes

5Understand RDS HA: automated backups have configurable retention period; HA mode maintains a standby replica; EasyCache Redis HA promotes standby when master fails; read replicas handle read scaling

6Learn Gamebase's scope: authentication (social login, guest, account mapping), in-app purchases, push notifications, operation console (bans, coupons), and game analytics (DAU, MAU, retention)

7Security Groups in NHN Cloud are stateful (return traffic automatically allowed); using another Security Group as the source rule source automatically allows all instances in that group without IP changes

8NHN Cloud is built on OpenStack — the Terraform OpenStack provider can manage NHN Cloud resources using custom endpoints
