The snap list command lists all installed Snap packages on the system. Snap is a package management system that is used for installing and managing software packages in Linux. It shows information about the installed Snap packages, including the version, publisher, and whether the package is active.

The command iptables -F will remediate and help resolve the issue. The issue is caused by the firewall rules that block the access to the organization’s web page and other services. The output of dmesg | grep firewall shows that the kernel has dropped packets from the source IP address 192.168.1.100 to the destination port 80, which is the default port for HTTP. The command iptables -F will flush all the firewall rules and allow the traffic to pass through. This command will resolve the issue and restore the access to the web page and other services. The other options are incorrect because they either do not affect the firewall rules (ip route flush or ip addr flush) or do not exist (iptables -R). References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 18: Securing Linux Systems, page 543.

Using AD Query, the security gateway connects to the Active Directory Domain Controllers using Lightweight Directory Access Protocol (LDAP). LDAP is a protocol that provides access to directory services over a network. AD Query uses LDAP queries to retrieve information about users and groups from Active Directory Domain Controllers without installing any software on them. AD Query does not use Windows Management Instrumentation (WMI), Hypertext Transfer Protocol Secure (HTTPS), or Remote Desktop Protocol (RDP) to connect to Active Directory Domain Controllers. References: Check Point Certified Security Administrator (CCSA) R80.x Study Guide, Chapter 5: User Management and Authentication, page 69.

To ensure all files created in Q1 inherit the group ownership of finance, the chmod g+s command sets the group ID (SGID) on the directory, ensuring new files belong to the group of the directory. chown Finance Q1/ changes the group ownership of Q1 to Finance, allowing Finance group members access. These settings facilitate collaborative permissions as per CompTIA Linux+ recommendations for group-based file sharing. Reference: CompTIA Linux+ Study Guide.
