Where KCNA Candidates Lose Points: The Trap of Similar Looking StrategiesMost KCNA candidates do not lose points because they never studied deployments. They lose points because the exam quietly tests the gaps between strategies that look similar on the surface. You read the question, recognize the topic, pick the answer that feels right and move on. Later you discover the wording was pointing at a different strategy entirely. The good news is that these traps are predictable and once you see them clearly, they stop costing you marks. Here is where Linux Foundation KCNA Questions tend to separate prepared candidates from candidates who only memorized definitions.RollingUpdate Versus Recreate: The Overlap TrapThis pair is the first place Linux Foundation KCNA Practice Questions catch people. RollingUpdate is the Kubernetes default and it gradually replaces old pods with new ones while keeping some capacity available. Recreate does the opposite. It terminates the old version first, then

Hi,I have a scenario where there is a button on an interface and when user clicks the button,we are performing background tasks like write records ,updating status and asynchronous subprocess. When the user clicks on the button ,it took around 5 seconds for the screen to disappear(Case Status changes to next stage) but when we tested with activity chaining the nodes till when the data is written in the records ,it took 1.5 seconds for screen to disappear and the process to get completed.Can someone please let me know what is the importance of activity chaining now in Appian and how does it make the execution of the nodes faster?

We are facing an issue with the Receive Message Event in an Appian Cloud application.Our application sends approval request emails to both internal and external users.

This is sort of my issue….KB-1923 Repeated "You Are Already Editing" warnings in Interface and Rule Designers | Appian Community But I’m using Edge, not Chrome. The biggest challenge is on deployment.  Whenever Appian thinks an object is actively being edited in the destination environment, any deployment I do for that object causes the package to fail to deploy….. even though no one is really editing the object anymore. is the only solution here to “Use Chrome” and apply the KB fix?

Enhancement Request:We would like to request an enhancement to Appian Designer search functionality to support exact phrase matching when searching within object types.Currently, searching for a sentence or multi-word phrase returns results based on individual keywords, making it difficult to locate specific expressions, rules, interface text, constants, process models, or other objects containing an exact sentence.Requested Functionality:Provide an option for exact phrase matching, similar to common search engines. Support syntax such as: "Faculty Appointment Committee" (quoted phrase) An "Exact Match" checkbox/filter in the search interface. Return only objects that contain the exact phrase in the same word order.

Hello Appian Community,I'm currently investigating password visibility behavior in an Appian Cloud environment running version 26.6.The native Appian username/password login page displays a masked password field, but there is no visible eye icon or Show/Hide Password option.Interestingly, the password visibility option appears to be available during the password reset/change workflow, creating an inconsistent user experience.I reviewed the following areas in the Administration Console: Authentication → Sign-In Page: Provides identity provider configuration, but no password visibility setting. Branding → Sign-In and Tempo: Provides logo and appearance customization, but no password visibility setting. I would appreciate clarification on the following: Does Appian 26.6 support a native Show/Hide Password toggle on the initial login screen? Is there a supported configuration or feature flag to enable this functionality? Why might password visibility be available during password rese

Here is the scenario:1) We have 2 different Appian applications running on the same instance2) Our organization policy requires us to have a SAML configuration per application, so we have 23) Each of these SAML configurations is configured to "Create new users upon sign in"4) The SSO Team passes the application name in the SAML attributesAppian displays the sign-in page and prompts the user to select the SAML configuration to use. We created Authentication Group rules to put someone in the group associated with the SAML config according to the attribute described in #4 above, but it does not work. The user gets 401 Unauthorized.

Hi everyone, I’m facing an issue with transferring my Appian certifications, Academy Online achievements, and badges from my current organization account to my personal account. I have already reached out to multiple teams, including Appian Technical Support, Appian Community, Academy Online support, and the Certifications team. I was informed that the request would be resolved within two working days. However, it has been longer than that, and I have not received any proper response or update despite multiple follow-ups. Has anyone faced a similar issue before? If so, could you please guide me on how to get this resolved or whom to contact for faster support? Any help or suggestions would be greatly appreciated. Thank you in advance!

Appian 24.1 My project receives a JSON document that is somewhere between 50 - 100 KB in size normally. We jamb it into a Record Type (as a json string), read it from a process model, convert this to a CDT (hierarchy), pass it to an interface (a hierarchy of them really). So far, all that we have built runs fine. Now we had a case where the JSON document was over 1 MB. This threw an error when we tried to write it to a record type. Apparently, there is a record size limit of 1 MB within Appian for tables that sync to record types. So, now we are looking at redesigning the data storage. Clearly, we need to break up/normalize the data into a set of relational tables (vs just 1 table as we have today). But from there I seem to have some options and I don't know what is best Option 1 - Read the record types within the process model and rebuild the JSON object so it may be passed to the interfaces.This moves the max size question from the table row to the process model variable. Can it
