Consolidating Multi-Project Monitoring in One Stackdriver Dashboard
You need to monitor resources that are distributed over different projects in Google Cloud Platform. You want to consolidate reporting under the same Stackdriver Monitoring dashboard. What should you do?
Community Insight
The question tests whether you understand that Stackdriver workspaces aggregate multiple projects, with the trap being that Groups (option D) are meant for organizing resources within a project, not for linking projects together.
When GCP resources span multiple projects, consolidating reporting requires a single Stackdriver (Google Cloud Monitoring) account—now called a workspace—into which every project is linked. The question establishes that option C is correct because one Stackdriver account can monitor any number of GCP projects under one set of dashboards.
Option D is the most common wrong pick: learners assume adding other project names as Group criteria unifies monitoring, but Groups filter resources by labels and metadata within a workspace—they do not attach additional projects to a Stackdriver account.

Why the Answer Is Correct
Option C is correct because a single Stackdriver (Google Cloud Monitoring) account, technically a workspace hosted by one project, can monitor any number of GCP projects once those projects are linked as monitored projects. Linking them places all their metrics, dashboards, and alerting policies under one account, which is exactly the consolidation of reporting under one dashboard the question asks for. This is Google's documented best practice for multi-project monitoring, and commenters such as leba cited the Stackdriver Monitoring documentation confirming that one workspace can watch many projects. Multiple community members independently arrived at C, including Buruguduystunstugudunstu and HansKloss611.Why the Other Options Are Wrong
Option A confuses networking with monitoring: Shared VPC connects project networks but does not itself aggregate Stackdriver data, and merely linking Stackdriver to one project without linking the others leaves their metrics uncollected. Option B is needlessly complex and wrong—creating a separate account per project produces siloed reporting, and a Stackdriver Account Editor service account in every project does not merge dashboards into one view. Option D fails because Groups are resource-grouping constructs built from criteria like instance names or labels within a workspace; as sahedge reported, adding two projects as group criteria did not work for them, and Agents89 noted that groups are for resource grouping, not project linking. kipsnak also observed that Stackdriver branding is now Google Cloud Monitoring and multi-project aggregation is done via a multi-project workspace—which is still option C in substance.Community Comment Notes
Commenters largely converged on C, with coldpar stating "C is correct not D" and ReyBan sharing the official link for adding monitored projects to a workspace. sahedge, with the most-liked comment, explained that D is incorrect because "Groups are used to define alerts on set of resources" and that project-based group criteria failed in practice. The sole dissent came from bryanchew, who argued D is needed because a workspace requires a hosting project—but that hosting-project requirement is satisfied by the single account in option C, so it does not make D correct. kipsnak helpfully warned that the Stackdriver name is legacy, yet the underlying multi-project workspace behavior still maps to option C.Official Reference
Exam Strategy
On consolidation questions, look for the option that creates ONE central object and attaches the rest to it; multi-object or per-object options almost always fragment reporting instead of unifying it. Remember that Shared VPC solves networking, not monitoring aggregation.
Frequently Asked Questions
Why is adding projects as a Group criterion (option D) wrong?
Groups filter resources inside an existing workspace using labels and metadata criteria; they cannot attach new projects to a Stackdriver account, so other projects' metrics would still go uncollected.
Does Shared VPC help consolidate Stackdriver dashboards across projects?
No. Shared VPC links project networks for traffic, not monitoring data; dashboards consolidate only when the projects are linked as monitored projects in one workspace.
