Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q44-Q49):

NEW QUESTION # 44
What is the core metric type in Prometheus used to represent a single numerical value that can go up and down?

A. Gauge
B. Summary
C. Histogram
D. Counter

Answer: A

Explanation:
In Prometheus, a Gauge represents a single numerical value that can increase and decrease over time, which makes D the correct answer. Gauges are used for values like current memory usage, number of in-flight requests, queue depth, temperature, or CPU usage-anything that can move up and down.
This contrasts with a Counter, which is strictly monotonically increasing (it only goes up, except for resets when a process restarts). Counters are ideal for cumulative totals like total HTTP requests served, total errors, or bytes transmitted. Histograms and Summaries are used to capture distributions (often latency distributions), providing bucketed counts (histogram) or quantile approximations (summary), and are not the "single value that goes up and down" primitive the question asks for.
In Kubernetes observability, metrics are a primary signal for understanding system health and performance.
Prometheus is widely used to scrape metrics from Kubernetes components (kubelet, API server, controller- manager), cluster add-ons, and applications. Gauges are common for resource utilization metrics and for instantaneous states, such as container_memory_working_set_bytes or go_goroutines.
When you build alerting and dashboards, selecting the right metric type matters. For example, if you want to alert on the current memory usage, a gauge is appropriate. If you want to compute request rates, you typically use counters with Prometheus functions like rate() to derive per-second rates. Histograms and summaries are used when you need latency percentiles or distribution analysis.
So, for "a single numerical value that can go up and down," the correct Prometheus metric type is Gauge (D).

NEW QUESTION # 45
Why are ServiceAccounts used in Kubernetes when assigning Role-Based Access Control (RBAC) permissions to Pods?

A. They let Pods authenticate to the API server securely without personal user credentials.
B. They are designed to provide a secure mechanism for storing application credentials inside Pods.
C. They are used to authenticate Pods by creating special user identities for administrators to manage.
D. They automatically assign Pods high-level cluster-admin permissions for accessing resources.

Answer: A

Explanation:
ServiceAccounts provide Pods with a dedicated, non-human identity that allows them to authenticate securely to the Kubernetes API server without relying on personal user credentials, enabling controlled and auditable access through RBAC.

NEW QUESTION # 46
What is the goal of load balancing?

A. To automatically measure and compare request performance across instances of an application.
B. To move and reschedule application instances across nodes in the cluster for efficiency.
C. To distribute traffic between different application versions as part of a deployment strategy.
D. To distribute requests evenly across instances of an application to improve availability and reliability.

Answer: D

Explanation:
The goal of load balancing is to distribute incoming requests evenly across multiple instances of an application, improving availability, reliability, and overall system performance by avoiding overload on any single instance.

NEW QUESTION # 47
Which of the following will view the snapshot of previously terminated ruby container logs from Pod web-1?

A. kubectl logs -c ruby web-1
B. kubectl logs -p ruby web-1
C. kubectl logs -p -c web-1 ruby
D. kubectl logs -p -c ruby web-1

Answer: D

NEW QUESTION # 48
What is the main purpose of a DaemonSet?

A. A DaemonSet ensures that the kubelet is constantly up and running.
B. A DaemonSet ensures that a process (agent) runs on every node.
C. A DaemonSet ensures that there are as many pods running as specified in the replicas field.
D. A DaemonSet ensures that all (or certain) nodes run a copy of a Pod.

Answer: D

Explanation:
The correct answer is A. A DaemonSet is a workload controller whose job is to ensure that a specific Pod runs on all nodes (or on a selected subset of nodes) in the cluster. This is fundamentally different from Deployments/ReplicaSets, which aim to maintain a certain replica count regardless of node count. With a DaemonSet, the number of Pods is implicitly tied to the number of eligible nodes: add a node, and the DaemonSet automatically schedules a Pod there; remove a node, and its Pod goes away.
DaemonSets are commonly used for node-level services and background agents: log collectors, node monitoring agents, storage daemons, CNI components, or security agents-anything where you want a presence on each node to interact with node resources. This aligns with option D's phrasing ("agent on every node"), but option A is the canonical definition and is slightly broader because it covers "all or certain nodes" (via node selectors/affinity/taints-tolerations) and the fact that the unit is a Pod.
Why the other options are wrong: DaemonSets do not "keep kubelet running" (B); kubelet is a node service managed by the OS. DaemonSets do not use a replicas field to maintain a specific count (C); that's Deployment/ReplicaSet behavior.
Operationally, DaemonSets matter for cluster operations because they provide consistent node coverage and automatically react to node pool scaling. They also require careful scheduling constraints so they land only where intended (e.g., only Linux nodes, only GPU nodes). But the main purpose remains: ensure a copy of a Pod runs on each relevant node-option A.
