Exam Professional Cloud Architect topic 1 question 157 discussion

Answer is D. Y'all not reading the fine details. The question is about aligning EACH client to their dedicated nodes (D), not to a node group (C). https://cloud.google.com/compute/docs/nodes/sole-tenant-nodes#default_affinity_labels The above reference clearly articulates the default affinity label for node group and node name. Unless we're thinking about growing each client to their own dedicated node groups (not in the current requirement), then the answer is not C, rather D. Compute Engine assigns two default affinity labels to each node: A label for the node group name: Key: compute.googleapis.com/node-group-name Value: Name of the node group. A label for the node name: Key: compute.googleapis.com/node-name Value: Name of the individual node.

D. Afinity should be set at node level, not node-group as every client has its own node in the group

affinity label only for dedicated nodes, not a node group. https://cloud.google.com/compute/docs/nodes/sole-tenant-nodes#default_affinity_labels

you cannot use node affinity labels based on the node group name.

Question already says node-group created "You created a sole-tenant node group and added a node for each client"

KV Affinity Label > Node template > Node Group > CE Question already said Node group is created. Then why tag it to node ?

Using node affinity labels based on the node group name when creating Compute Engine instances is the appropriate method to ensure workloads are hosted on the correct node group. This approach aligns with Google Cloud's recommended practices for provisioning sole-tenant VMs and provides the required isolation for client workloads.

D As per the documentation: https://cloud.google.com/compute/docs/nodes/provisioning-sole-tenant-vms#provision_a_sole-tenant_vm

D, the question ask “You created a sole-tenant node group and added a node for each client.”，so node affinity labels based on the node name is need it.

I had this question recently (end of jan 2023) and went with answer D. After doing some investigation, that seems to be the right answer to me.

Answer is D. Ref: you can't specify node affinity labels on a node group.>> https://cloud.google.com/compute/docs/nodes/sole-tenant-nodes#node_templates

D is the correct answer

D is ok

D is the correct answer, VMs must be associated to a specific node within the node-group, so you must use the node name label to provision the VM.

D is right, Node is right choice instead of node group

D : https://cloud.google.com/compute/docs/nodes/sole-tenant-nodes Node affinity labels are key-value pairs assigned to nodes, and are inherited from a node template. Affinity labels let you: Control how individual VM instances are assigned to nodes. Control how VM instances created from a template, such as those created by a managed instance group, are assigned to nodes. Group sensitive VM instances on specific nodes or node groups, separate from other VMs.

I go with C as I believe single-tenant node group meant for only one client
