D338 Cloud Platform Solutions carries the banner number ITCL 3204 and is worth 3 competency units. It is a cloud system administration course: managing user access groups, implementing single sign on, deploying servers, and configuring virtual machines so they stay available, scale, perform and remain secure. D338 and ITCL 3204 are one requirement. Where an architecture course asks what you would design, this one asks what you would actually do, in what order, and what you would check afterward.
Administration is design that has to survive Monday
The gap between an architecture diagram and a running environment is filled with decisions nobody draws: how groups are named, who is allowed to create resources, what a virtual machine is sized at, what happens when it needs to be patched, and who notices when it stops. D338 lives in that gap. The course rewards writing that is operationally concrete, because a system administrator's plan is judged by whether somebody else could execute it.
Access groups are the first real lesson. Assigning permissions to individuals works for about a week and then becomes unmaintainable, which is why permissions attach to groups and people attach to groups. Getting the group model right means deciding what the groups represent: job function, project, environment, or some combination. A model built around functions survives reorganization far better than one built around named individuals or single projects.
Single sign on is worth understanding as a trust relationship rather than a convenience feature. One directory becomes the authority on identity and other systems agree to accept its word. The benefits follow from that: one place to disable an account, one place to enforce authentication requirements, one audit trail. So do the risks, since a compromised central identity now reaches everything that trusts it, which is why conditional requirements and strong authentication belong in the same conversation.
Virtual machine configuration is where availability, scale, performance and security stop being abstractions. Sizing is a performance and cost decision at the same time. Placement across fault domains is an availability decision. Image and patch strategy is a security decision that becomes an availability decision the moment a reboot is required. Naming each of those decisions and its tradeoff is the substance of most work in this course.
Outcomes are Competent or Not Competent at WGU, letter grades and an ordinary grade point average are absent, and the 3 competency units of D338 fall within a flat rate six month term.
Turning scored aspects into an administration plan
If your version of D338 is assessed by a performance assessment, the aspects your evaluator scores are the plan's sections. WGU requires a score of 2 in every aspect for a task to pass and judges each aspect on its own, so a thorough access model will not carry a thin section on virtual machine configuration.
Budget before drafting. Suppose a rubric of five scored aspects with a target near 1,750 words, which suits a document where configuration tables carry part of the load. Reserve 125 words for the organization and its workloads, and 95 for the close, leaving 1,530. The single heaviest aspect, usually the virtual machine deployment and its configuration for availability, scale, performance and security, takes 450 words, because it is really four decisions in one aspect. The four remaining aspects, typically covering group design, single sign on, server deployment approach and monitoring, take 270 each for 1,080. Adding 450 to 1,080 gives 1,530 exactly.
Use tables for anything that is a setting and prose for anything that is a decision. A table of group names, their members and their permissions communicates instantly. What it cannot do is explain why the model is built that way, and the reasoning is what the aspect scores.
Keep budget for verification. For each configuration you specify, one sentence saying how you would confirm it is in effect turns a plan into something operable, and it is nearly always the difference between a section that reads as competent and one that reads as theoretical.
Shape for a cloud administration plan
D338 deliverables usually set up and run an environment for a described organization. These proportions carry that plan.
| Section | What belongs there | Share |
|---|---|---|
| Environment and users | What is being run, who uses it, and what roles exist in the organization. | 11 percent |
| Group and access model | What the groups represent, their permissions, and how membership is granted and removed. | 18 percent |
| Single sign on | The identity authority, what trusts it, the sign in requirements, and the disable path. | 16 percent |
| Server deployment | How servers are built, from what image, and how a rebuild is repeated identically. | 15 percent |
| Virtual machine configuration | Sizing, placement, scaling behavior, patching and host level security, each with its tradeoff. | 24 percent |
| Monitoring and verification | What is watched, what alerts, and how each configuration is confirmed in effect. | 11 percent |
| Close | The part of the environment most likely to drift and how you would catch it. | 5 percent |
Documenting administrative decisions
The sourcing standard in an administration document is practical. Platform behavior comes from provider documentation, cited with a date, because defaults and limits change between releases. Practice recommendations come from published benchmarks and hardening guidance rather than from a forum answer, and naming the specific benchmark control is stronger than naming the benchmark.
Write settings so they are unambiguous. A configuration described as hardened tells a reader nothing. The same configuration described as built from a specific image, with a stated patch cadence, remote administrative access restricted to a named group, and host firewall rules limited to the ports the application needs, can be implemented and checked by someone else.
Where a decision involves cost, describe the driver rather than a price. Saying that a larger instance improves performance headroom at a continuous cost, while automatic scaling trades a slower response to demand spikes for lower steady spend, will still be true next year. A quoted rate will not.
Use the citation style your task specifies and cite at the point of the claim, including in table cells. Where you include a screenshot or configuration export as evidence, label it and say what it demonstrates, since an unlabeled artifact proves nothing to an evaluator working through a rubric.
What earns Competent, and what comes back
Competent work is executable. Groups have a stated logic and a joiner and leaver path. Single sign on names the authority and what happens when an account is disabled. Servers are built from something repeatable. Virtual machine settings each carry a reason and a tradeoff. And every configuration has a way to confirm it took effect.
Returns cluster in five places. Permissions are assigned to individuals rather than groups. Single sign on is described as a benefit rather than as a trust relationship with requirements attached. The four virtual machine properties are collapsed into one paragraph, so at least one of them goes unaddressed. Deployment is described manually, with no path to rebuilding the same server twice. Or monitoring is listed with no thresholds and no responder.
A quick check before submitting: for each of availability, scalability, performance and security, point at the specific setting in your plan that addresses it. If any of the four has no setting behind it, that is the part of the aspect an evaluator will find first.
Because revision and resubmission of a performance assessment carry no grade penalty at WGU, submit as soon as every aspect has a genuine answer. If your section also carries an objective assessment, that exam is proctored and our boundary is absolute: preparation only, with configuration reasoning drills, terminology work and a candid read of your preassessment result. We will not sit an assessment, we take no role once one begins, and we neither request portal credentials nor hold them.
Plan reads like theory?
Send the D338 rubric and your scenario. We rebuild it as an executable plan, with a group model, a sign in path and four separate virtual machine decisions.
Six mistakes that cost time in D338
- Permissions on individuals. Groups are the unit that survives staff changes. Say what each group represents and how membership moves.
- Single sign on as a convenience. It is a trust relationship. Name the authority, the requirements it enforces and the disable path.
- Collapsing the four virtual machine properties. Availability, scalability, performance and security each need their own setting and tradeoff.
- Manual server builds. If a server cannot be rebuilt identically, the environment cannot be recovered or audited.
- Settings with no verification. Say how you would confirm each configuration is actually in effect.
- Monitoring without thresholds. A metric with no threshold and no responder is a dashboard, not a control.

The assessments, one by one
The public catalog does not publish this course's PA/OA identity or task count. WGU Tutors publishes at most one PA manual per course and only from a WGU-controlled public rubric. Until that source exists, PA help begins from the student's real Course of Study and OA support remains preparation only.
