NEW QUESTION # 75
You are running a microservice-based application in Kubernetes. Each service has its own HPA configured for scaling. How can you ensure that the scaling decisions for different services are coordinated to prevent resource contention?
Answer: A,D
Explanation:
Both resource quotas and a custom controller can help prevent resource contention. Resource quotas limit the resources each service can consume, preventing one service from monopolizing resources- A custom controller can monitor resource usage across all services and make coordinated scaling decisions to avoid over-provisioning and resource exhaustion.
NEW QUESTION # 76
A request for 500 mebibytes of ephemeral storage must be specified in a YAML file. How should this be written?
Answer: D
Explanation:
In Kubernetes, resource quantities must be expressed using specific, well-defined units. When requesting ephemeral storage, Kubernetes follows the same quantity format rules as other resources such as memory.
These rules distinguish between binary units (base-2) and decimal units (base-10), and the correct unit must be used to avoid configuration errors or unintended resource allocation.
The term mebibyte (MiB) is a binary unit equal to 2²# bytes (1,048,576 bytes). Kubernetes represents mebibytes using the suffix Mi with a capital "M" and lowercase "i". Therefore, a request for 500 mebibytes of ephemeral storage must be written as 500Mi, making option A the correct answer.
Option B, 500mi, is incorrect because Kubernetes resource units are case-sensitive. The lowercase mi is not a valid unit and will be rejected by the API server. Option C, 500m, is also incorrect because the suffix m represents millicpu when used with CPU resources and has no meaning for storage quantities. Using m for ephemeral storage would result in a validation error. Option D, 0.5M, is incorrect because M represents a decimal megabyte (10# bytes), not a mebibyte, and Kubernetes best practices require binary units for memory-based resources like ephemeral storage.
Ephemeral storage requests are typically defined under the container's resources.requests.ephemeral-storage field. Correctly specifying the unit ensures that the scheduler can accurately account for node storage capacity and enforce eviction thresholds when necessary.
In summary, Kubernetes requires precise, case-sensitive units for resource specifications. Since the question explicitly asks for 500 mebibytes, the only valid and correct representation is 500Mi, which aligns exactly with Kubernetes resource quantity conventions.
NEW QUESTION # 77
Which are the two primary modes for Service discovery within a Kubernetes cluster?
Answer: C
Explanation:
Kubernetes supports two primary built-in modes of Service discovery for workloads: environment variables and DNS, making A correct.
Environment variables: When a Pod is created, kubelet can inject environment variables for Services that exist in the same namespace at the time the Pod starts. These variables include the Service host and port (for example, MY_SERVICE_HOST and MY_SERVICE_PORT). This approach is simple but has limitations: values are captured at Pod creation time and don't automatically update if Services change, and it can become cluttered in namespaces with many Services.
DNS-based discovery: This is the most common and flexible method. Kubernetes cluster DNS (usually CoreDNS) provides names like service-name.namespace.svc.cluster.local. Clients resolve the name and connect to the Service, which then routes to backend Pods. DNS scales better, is dynamic with endpoint updates, supports headless Services for per-Pod discovery, and is the default pattern for microservice communication.
The other options are not Kubernetes service discovery modes. Labels and selectors are used internally to relate Services to Pods, but they are not what application code uses for discovery (apps typically don't query selectors; they call DNS names). LDAP and RADIUS are identity/authentication protocols, not service discovery. DHCP is for IP assignment on networks, not for Kubernetes Service discovery.
Operationally, DNS is central: many applications assume name-based connectivity. If CoreDNS is misconfigured or overloaded, service-to-service calls may fail even if Pods and Services are otherwise healthy. Environment-variable discovery can still work for some legacy apps, but modern cloud-native practice strongly prefers DNS (and sometimes service meshes on top of it). The key exam concept is: Kubernetes provides service discovery via env vars and DNS.
NEW QUESTION # 78
You are deploying a multi-container pod with each container requiring different resource limits. What Kubernetes resource allows you to define these individual limits?
Answer: D
Explanation:
The 'PodSpec' allows you to define resources for each container within the pod- You can specify 'requests' and 'limits' for CPU and memory resources, ensuring that each container receives the appropriate resources- ResourceQuota and LimitRange are used for enforcing resource usage limits across multiple pods, not within a single.
NEW QUESTION # 79
Let's assume that an organization needs to process large amounts of data in bursts, on a cloud- based Kubernetes cluster. For instance: each Monday morning, they need to run a batch of 1000 compute jobs of 1 hour each, and these jobs must be completed by Monday night. What's going to be the most cost-effective method?
Answer: C
