The correct answer is C . Duplicate user creation during a grid migration is commonly tied to identity mismatch. Slack must be able to match migrating users to the correct enterprise identity, and the most important identifier in this context is the user's email address. Ensuring that users' Slack email addresses match their SSO identity reduces the chance that Slack treats the same person as separate accounts during migration. Option A is incorrect because promoting guests to full members does not solve identity matching and may increase access risk. Option B is wrong because requiring login with an existing email and password does not address SSO alignment and is not the best migration control. Option D is also incorrect because usernames are not the primary identity-matching control for Enterprise Grid migration. The consultant should focus on pre-migration identity hygiene: validate email addresses, align with SSO, resolve duplicate or stale accounts, and coordinate with identity administrators before migration execution.

The correct answer is D. A strong Slack learning plan must be tailored to the client's current Slack maturity, audience size, admin/user mix, geographic distribution, and language needs. The client's current use of Slack determines whether training should focus on basic navigation, behavior change, migration differences, advanced workflows, or admin operations. The number of Admins and Users affects scale, delivery method, scheduling, and whether enablement should include live training, videos, office hours, documentation, champions, or self-serve resources. Time zones and languages are critical for global rollout planning because a single live session may exclude entire regions or reduce training effectiveness. Option A incorrectly includes the brand of video conferencing tool, which is not a primary design consideration. Option B includes cloud storage, which may be relevant for integrations but not core learning-plan tailoring. Option C again overweights video conferencing brand and omits time zones/languages. The consultant should design enablement around user population, Slack maturity, and accessibility across regions.

The correct answers are A and B . Before launch, Enterprise Grid admins should make sure the essential app ecosystem is ready and governed. Installing and pre-approving a list of trusted apps gives users immediate access to approved productivity tools and reduces friction at launch. Establishing an app approval process is equally important because it defines how future app requests will be submitted, reviewed, approved, restricted, or rejected. Option C is useful as part of enablement, but the question asks which app rollout best practices should be completed before launch, and policy/process readiness comes first. Option D may apply when migrating an existing Slack environment with installed apps, but it is not the universal best answer for app rollout. Option E is valuable for ongoing app governance, but usage tracking and business-owner documentation are lifecycle practices, not the two most immediate pre-launch requirements. App launch readiness requires both approved apps and a clear approval model.

The correct answer is D . During discovery, the consultant must understand the client's current collaboration model and the pain points behind the business issue. The problem is not simply that shipments and announcements exist; the issue is that employees are not reliably informed. That points to gaps in communication workflows, channel strategy, announcement practices, operational visibility, and collaboration behavior. Option A is useful background, but the survey has already identified symptoms. The consultant now needs to understand why those symptoms occur. Option B is too narrow because shipment schedules alone will not explain broader employee communication breakdowns. Option C is unfocused and may produce irrelevant project noise. Option D is the strongest because it investigates the collaboration patterns that Slack is meant to improve: how teams communicate today, where information gets lost, who owns announcements, which channels exist, and how frontline or operational updates are distributed.

The correct answer is B . The client wants to replace email and mandatory meetings with Slack channel updates, but they are concerned employees may miss important information. An org-wide default channel that is required is the best match because it ensures employees are automatically placed into the channel and cannot treat the channel as merely optional. This supports broad communication reach and reduces the risk of employees missing periodic updates. Option A is insufficient because an optional default channel does not fully address the concern that employees may miss updates. Option C, a multi-workspace public channel, may distribute communication across workspaces, but it does not by itself guarantee that all relevant employees are included or required to remain. Option D is close but less precise; the tested Slack channel type is specifically an org-wide default channel marked required. For enterprise communications, channel strategy must balance visibility, membership enforcement, and message discipline. A required org-wide default channel provides the strongest controlled communication path.
