Q1Domain Verified
When configuring a Vultr Kubernetes Engine (VKE) cluster for a highly available application, which of the following is the most critical consideration for the control plane's resilience?
Ensuring the node pool has a minimum of 3 worker nodes.
Utilizing Vultr's managed Kubernetes offering for automatic control plane replication.
Implementing a robust ingress controller with multiple replicas across different nodes.
Deploying the VKE cluster in a single Vultr region with multiple availability zones.
Q2Domain Verified
A user is experiencing slow application response times within their VKE cluster and suspects network latency. Which Vultr networking feature, when leveraged correctly, can significantly mitigate this issue for intra-cluster communication?
. B) Direct Connect to Vultr's backbone network.
Private networking between VKE nodes and other Vultr resources.
Vultr Load Balancers with global server load balancing (GSL
Vultr's Content Delivery Network (CDN) for static assets.
Q3Domain Verified
During a VKE cluster upgrade, a critical application deployed via a StatefulSet fails to restart due to persistent `CrashLoopBackOff` errors, even though the application logs indicate no obvious code issues. Which of the following VKE or Kubernetes concepts is most likely the root cause of this situation in a specialist context?
A misconfiguration in the PodDisruptionBudget (PDB) preventing graceful node drains.
The application's persistent volume claim (PVC) not being correctly detached from the old pod before the new one starts.
A lack of readiness probes, leading the kubelet to consider the pod healthy prematurely.
Insufficient memory allocated to the StatefulSet pods.
