 ## Exercises
 
-::::{dropdown} Challenge Title
+::::{dropdown} Which of the following statements are True/False?
+:open:
+
+a. 2i2c-managed hubs are only available via a single cloud provider.  
+b. A hub can be accessed and used by anyone who knows its URL.  
+c. Software environments are inflexible and irreproducible.  
+d. 2i2c provides operations support for your hub.
+
+:::{dropdown} Solution
+a. False – Hubs are built entirely with open source and community-driven tooling. The Right to Replicate gives communities the right to replicate their infrastructure in its entirety elsewhere.  
+b. False – Hub Champions can control who can access the hub through GitHub or other authentication methods.  
+c. False – Software environments are managed by Hub Champions and automatically deployed with containerisation, allowing for scalability across the cloud and reproducible user environments.  
+d. True – 2i2c engineers maintain service availability, uptime and operational upgrades. Hub Champions are responsible for hub configuration and management to support their user community.

+- What domain of expertise does your community have?
+- How large is your community? Do they work alone or do they need to collaborate together?
+- Does your community work with large datasets?
+- Does your community need access to intense computational power?
+- Where applicable, are the needs for collaboration, large datasets, and/or computational power consistent across your whole community?
+- What are the main software applications your community uses to conduct their work? 
+- How familiar is your user community with version control using git/GitHub?
+
+Prepare to summarise and share with the rest of the workshop.

+
+::::{dropdown} In which of the following ways should a Hub Champion support their users?
 :open:
 
-Challenge content
+a. Providing community guidance on best research software practices for users of your hub.  
+b. Troubleshooting and supporting common user issues.  
+c. Communicating infrastructure level requests and incidents to 2i2c.  
+d. Overseeing user access policy to the hub.
 
 :::{dropdown} Solution
