Grading Rubric

Criterion	Strong (3)	Adequate (2)	Weak (1)
Identified misleading symptom	Tested git clone directly on the host; distinguished between SSH agent and network connectivity issues quickly	Investigated Ansible config and SSH settings first, then tested direct connectivity	Spent extended time comparing host configurations or Ansible task parameters
Found root cause in linux_ops domain	Found both the sudoers issue and the network block; correctly identified the network as the primary cause	Found the SSH agent issue but not the security group firewall rule	Assumed it was purely an Ansible configuration or SSH key problem
Remediated in networking domain	Updated security group, fixed sudoers, updated provisioning template	Fixed the security group but not the sudoers or provisioning template	Worked around it by using HTTPS git clone or copying the key manually
Cross-domain thinking	Explained the dual-issue nature: firewall was the primary block, sudoers was a secondary issue; proposed eliminating agent forwarding	Acknowledged both issues but treated them as equal weight	Treated it as a single-domain Ansible or SSH problem

Prerequisite Topic Packs

• ansible — needed for Domain A investigation (playbook tasks, SSH connection, become/sudo)
• ssh-deep-dive — needed for Domain B root cause (agent forwarding, SSH_AUTH_SOCK, sudo environment)
• linux-users-and-permissions — needed for Domain B (sudoers configuration, env_keep)
• firewalls — needed for Domain C remediation (security groups, egress rules)
• aws-networking — needed for Domain C (AWS security groups, VPC subnet routing)
