Question No : 1
Which Kubernetes resource assists with rolling updates during HA deployments?

A.ReplicaSet
B.Deployment
C.Secret
D.Ingress

正解:
Explanation:
Deployments manage rolling updates by gradually replacing old pod versions with new ones. This minimizes downtime and ensures Automation Suite services remain available during upgrades.

Question No : 2
How often should Velero snapshots be taken for critical Automation Suite clusters?

A.Weekly
B.Monthly
C.Based on RPO requirements
D.Only after upgrades

正解:
Explanation:
Snapshot frequency should align with the Recovery Point Objective (RPO) for your organization. The lower the RPO, the more frequently snapshots must be taken to minimize data loss.

Question No : 3
Which setting must be tuned for PostgreSQL in active/active DR?

A.Shared_buffers = 0
B.Autocommit = off
C.Replication slots and WAL archiving
D.SSL_mode = disable

正解:
Explanation:
For active/active setups, replication slots and Write-Ahead Log (WAL) archiving are crucial to keep replicas in sync. They enable real-time data flow between regions or nodes.

Question No : 4
How do multi-zone Kubernetes clusters help in HA?

A.Run pods as root
B.Enable high TTL routing
C.Spread workloads across availability zones
D.Use fewer service accounts

正解:
Explanation:
Running the Kubernetes cluster across multiple availability zones allows workloads to survive a zone-level failure. It improves fault isolation and contributes to high availability.

Question No : 5
Which Kubernetes CRDs must be restored during DR failover?

A.Deployments and DaemonSets only
B.All objects in kube-system
C.All resource types backed by Velero
D.ReplicaSets only

正解:
Explanation:
During DR, all CRDs (Custom Resource Definitions) and other objects backed up by Velero―including services, secrets, and PVCs―must be restored to replicate the original cluster state.

Question No : 6
What is a limitation of active/active DR in Automation Suite?

A.Cannot be used with Orchestrator
B.Requires low TTL DNS
C.Needs complex database replication
D.Doesn’t support TLS

正解:
Explanation:
Active/active DR involves running two active environments simultaneously, which demands complex synchronization of services and database replication. Without it, data inconsistency may occur.

Question No : 7
How can you test your active/passive DR configuration in Automation Suite?

A.Change hostnames on all nodes
B.Disable core pods manually
C.Simulate region failure and trigger restore on passive cluster
D.Pause Kubernetes API server

正解:
Explanation:
A proper DR test involves simulating a failure and restoring the suite on the passive cluster using Velero.
This validates snapshot integrity, cluster readiness, and failover procedures.

Question No : 8
What does Velero back up during a scheduled snapshot?

A.Node hardware stats
B.Kubernetes objects and persistent volumes
C.Helm installation logs
D.Docker layer cache

正解:
Explanation:
Velero backs up Kubernetes cluster objects (like deployments, services) and persistent volume data. It ensures Automation Suite state can be restored quickly in a DR event.

Question No : 9
In an HA setup, how is data integrity preserved for services like Orchestrator?

A.Using temporary in-memory storage
B.With persistent volumes and PostgreSQL replication
C.With local filesystem caching
D.By running multiple pods on the same node

正解:
Explanation:
Persistent volumes ensure data survives pod restarts, while PostgreSQL replication maintains transactional integrity. This approach guarantees consistent and reliable storage for key services like Orchestrator.

Question No : 10
Which Kubernetes mechanism helps maintain pod availability across multiple nodes?

A.InitContainers
B.StatefulSet
C.ReplicaSet
D.Admission Controller

正解:
Explanation:
ReplicaSets ensure a specified number of pod replicas are running at all times. They are essential for maintaining high availability by rescheduling pods when failures occur in multi-node setups.

Question No : 11
Which two benefits are gained by enabling HA in Automation Suite? (Select two)

A.Automated snapshot recovery
B.Zero downtime during node failure
C.Simplified node-to-pod network
D.Scalability and service resilience

正解:
Explanation:
HA provides continuous service availability even during infrastructure issues and allows services to scale across nodes. This improves Automation Suite’s fault tolerance and performance under load.

Question No : 12
Which condition must be met for DNS-based failover to work in DR?

A.Dedicated DHCP server
B.DNS records with TTL close to zero
C.NTP synchronization
D.Localhost DNS override

正解:
Explanation:
Short TTL values in DNS records ensure clients resolve the new active site faster during failover. This enables quick redirection to the disaster recovery site when the primary becomes unavailable.

Question No : 13
What is the benefit of using HAProxy in Automation Suite HA deployments?

A.Provides terminal access to pods
B.Acts as centralized monitoring
C.Load balancing across service endpoints
D.Maintains Docker image cache

正解:
Explanation:
HAProxy provides TCP/HTTP load balancing, routing requests to healthy service endpoints. In an HA Automation Suite setup, it ensures requests are always routed to responsive backend pods or nodes.

Question No : 14
Which of the following best describes an active/passive deployment?

A.Both clusters run in parallel
B.A backup cluster remains idle until activated
C.Only the active cluster receives updates
D.Users switch manually between clusters

正解:
Explanation:
In an active/passive setup, the passive cluster stays idle and only becomes active during disaster events.
It’s updated periodically through backups and is brought online through a failover process.

Question No : 15
Which two components must be synchronized between active/passive clusters for DR readiness? (Select two)

A.Velero backup repositories
B.Ingress rules
C.Kubernetes logs
D.CronJob objects

正解:
Explanation:
Backup repositories and Ingress configurations must be identical across clusters. This ensures that services can route traffic correctly after failover and that data restoration is accurate and complete.
