The key here is performing the task without affecting any of the other services.
C. Create a new service object for TELNET and set the maximum session TTL: By creating a new service object specifically for TELNET and setting the maximum session TTL, you can control the idle session timeout for Telnet connections established through the SSL VPN.
D. Create a new firewall policy and place it above the existing SSLVPN policy for the SSL VPN traffic, and set the new TELNET service object in the policy: Creating a new firewall policy and placing it above the existing SSLVPN policy allows you to apply the new TELNET service object with the modified session TTL, ensuring that the idle session timeout does not occur after 90 minutes.
- Not A - Changing the maximum TTL value for TELNET will affect every other policy that references the TELNET service
- Not B - Changing the session TTL on the SSLVPN policy will impact other services referenced in the policy.
