Section 3: Scheduling (11-16)

Based on the image.

The purpose of __________ is to ensure that PODs are hosted on particular nodes, in this way to ensure the large data processing POD ends up on the Node-1

• Scheduler

• Node Selector

• Node Affinity

• Affinity rules

"Defines the affinity rules for the Pod."

Which of the parameters set under "spec" in a POD definition for a Node Affinity configuration, does the above statement refer to?

(a)  

"Defines the node affinity rules"

Which of the parameters set under "spec" in a POD definition for a Node Affinity configuration, does the above statement refer to?

(a)  

"This is a list of node selector terms that must be satisfied for the affinity to apply."

Which of the parameters set under "spec" in a POD definition for a Node Affinity configuration, does the above statement refer to?

(a)  

"Defines the match expressions that must be satisfied on nodes"

Which of the parameters set under "spec" in a POD definition for a Node Affinity configuration, does the above statement refer to?

(a)  

"The name of the node label to be evaluated. In this case, the label is "size"."

Which of the parameters set under "spec" in a POD definition for a Node Affinity configuration, does the above statement refer to?

(a)  

"The comparison operator to use. In this case, "In" indicates that it should look for the value of the label within a list of values."

Which of the parameters set under "spec" in a POD definition for a Node Affinity configuration, does the above statement refer to?

(a)  

"The list of values that must be satisfied for the affinity to apply. In this example, the value "Large" indicates that it prefers to schedule the Pod on nodes that have a "size" label with the value "Large" "
