Exam Professional Cloud Architect topic 1 question 31 discussion

it should be A .. helm is needed for "Deploy application bundles using dynamic templates" Load Balancing should be part of GKE Already

D. Google Kubernetes Engine, Jenkins, and Cloud Load Balancing

1. Open-source technology: Kubernetes Engine, Jenkins, and Helm. 2. Dynamically scale compute capacity: Kubernetes Engine provides autoscaling to adjust the number of nodes based on demand. 3. Support continuous software delivery: Jenkins enables CI/CD pipelines for automated building, testing, and deployment of applications. 4. Run multiple segregated copies: Kubernetes Engine allows deploying multiple instances of the application in isolated environments (namespaces) within the same cluster. 5. Deploy application bundles using dynamic templates: Helm uses charts (templates) to define, install, and upgrade Kubernetes applications. 6. Route network traffic based on URL: Kubernetes Engine's service objects and ingress controllers can route traffic to specific services based on URLs and other criteria.

Based on: "Be based on open-source technology for cloud portability", I go for A, because it is more portable, as compare to D.

Choose A

Yes, Kubernetes can route network traffic to specific services based on URL using Ingress and Ingress controllers Answer is A

Load Balancer is required as per point 6. Jenkins satisfies point 3. D is correct

D is correct

Option A (GKE, Jenkins, Helm) meets most requirements except for explicit URL-based routing, though Kubernetes Ingress (which can be managed through Helm charts) implicitly covers this. Option D (GKE, Jenkins, Cloud Load Balancing) directly meets every requirement, including URL-based routing without needing to infer capabilities or integrate additional tools beyond the scope of what's listed. Jenkins supports continuous delivery, GKE supports dynamic scaling, segregated application stacks, and cloud portability. Cloud Load Balancing directly addresses the URL-based routing requirement.

D is OK

1. Be based on open-source technology for cloud portability: GKE 2. Dynamically scale compute capacity based on demand: GKE 3. Support continuous software delivery: Jenkins 4. Run multiple segregated copies of the same application stack: GKE 5. Deploy application bundles using dynamic templates -> Jenkins 6. Route network traffic to specific services based on URL -> Only HTTPs load balancer can meet this requirement: Next best is Cloud balancing (that can be either Network or HTTPs), So D makes sense to me.

D - Correct

I thought that answer A was correct but after researching HELM I think now the option D is correct. Helm is not a cloud service on its own, and it is not built into Google Kubernetes Engine (GKE). Helm is an open-source package manager for Kubernetes that simplifies the deployment and management of applications on Kubernetes clusters. Here's a brief overview: Helm: Helm allows you to define, install, and upgrade even the most complex Kubernetes applications using packages called charts. A Helm chart includes pre-configured Kubernetes resources that define the structure of an application. Helm provides a convenient way to package, version, and deploy applications on Kubernetes.

Kubernetes natively supports routing to different services based on URLs via the ingress gateway regardless of wether a LB is used...

The correct answer is A, you can route network traffic to specific services based on URL using Google Kubernetes Engine (GKE) using Ingress

Correct should be D, Focus on this part of the question "what cloud technologies he can use to meet them", And Now coming to options ,B,C are self explanatory now coming to A Because Helm is not a Cloud Technology first, its just a package Manager for Kubernetes, and Even if you say Loadbalncing is part of GKE , actually whatever ingress you create for path based , It does create a load Balancer , and ultimately LOad Balancer is Definitely important, now coming to Templating I Feel there can be many tools we can use ex: Kustomize can be one of them but that is completly something User can decide and even create some customised way to templatize the deployment using YAML or shell or any other language .

Correct answer is D - Don't get confused with this option "Deploy application bundles using dynamic templates". In this option, they have mentioned as "Deploy applications". In GKE app deployment, can be configured using YAML files. Helm is not a highly preferred tool and that won't be a recommedation from Google. Answer is D
