At standup, a dev mentions watching a recorded, anonymized playback of exactly how a specific user navigated and interacted with the site before encountering an error. What is this capability called?
Session replay reconstructs a recorded, typically anonymized playback of exactly how a specific user moved through and interacted with the site, letting a team directly observe the sequence of clicks and navigation leading up to an error rather than only seeing an aggregate count of how many users encountered it. This turns an abstract error metric into a concrete, observable sequence of events. It's especially valuable for reproducing and understanding a bug that's hard to describe from a support ticket alone.

During a design review, the team wants sensitive form fields, like a password or payment number, automatically excluded from a recorded session replay. Which capability supports this?
Automated sensitive-data masking in replays automatically excludes or obscures sensitive form field values, like a password or payment number, from being captured in the recorded session in the first place, rather than recording everything and relying on a manual redaction process afterward. This is an essential privacy and security safeguard for any tool capturing detailed user interaction data. Configuring this masking correctly, and verifying it actually catches every sensitive field, is a critical setup step before enabling session replay broadly.

In a code review, a dev notices a specific session replay was automatically flagged because it included several rapid, repeated clicks on a non-responsive element, a pattern known to indicate user frustration. What does this represent?
Rage-click detection automatically identifies a pattern of several rapid, repeated clicks on the same non-responsive element, a behavior strongly associated with user frustration, and flags the session for review without requiring someone to manually watch every recording to spot it. This surfaces a likely usability problem proactively rather than depending on a user to explicitly report it. It's one of several automated behavioral signals used to prioritize which recorded sessions are actually worth a team's limited review time.

An incident report shows a session replay tool captured and displayed a user's sensitive medical information typed into an unmasked custom form field that wasn't covered by the default masking rules. What practice would prevent this?
Explicitly auditing every custom field, especially one outside the tool's standard, commonly recognized patterns, catches sensitive content that default masking rules alone might miss. Assuming default rules automatically cover every custom field overestimates how comprehensive an out-of-the-box configuration really is for a specific, non-standard site. This proactive audit is an essential step before capturing session replay on any site with unusual or sensitive custom form fields.

During a PR review, a teammate asks why the team uses session replay instead of relying solely on aggregate analytics, like page views and click counts, to understand a usability problem. What is the reasoning?
Aggregate analytics, like a raw page view or click count, shows that something happened at scale but not the specific sequence or context behind any individual instance. Session replay fills that gap by showing exactly how a specific user actually interacted with the page leading up to a problem. The tradeoff is the added responsibility of properly masking sensitive data, since session replay captures far more detailed, potentially sensitive interaction data than an aggregate metric ever would.
What does the "FullStory Session Replay Vocabulary" vocabulary exercise cover?
This exercise tests real IT vocabulary related to fullstory session replay vocabulary through 5 multiple-choice questions, each built from realistic workplace sentences rather than abstract definitions.
