Which characteristic distinguishes Ansible from Chef?

• A.Ansible lacs redundancy support for the master server. Chef runs two masters in an active/active mode.
• B.Ansible uses Ruby to manage configurations. Chef uses YAML to manage configurations.
• C.Ansible pushes the configuration to the client. Chef client pulls the configuration from the server.
• D.The Ansible server can run on Linux, Unix or Windows. The Chef server must run on Linux or Unix.

Correct Answer: C

Explanation
The established keyword is only applicable to TCP access list entries to match TCP segments that have the ACK and/or RST control bit set (regardless of the source and destination ports), which assumes that a TCP connection has already been established in one direction only. Let's see an example below:

Suppose you only want to allow the hosts inside your company to telnet to an outside server but not vice versa, you can simply use an "established" access-list like this: access-list 100 permit tcp any any established access-list 101 permit tcp any any eq telnet ! interface S0/0 ip access-group 100 in ip access-group 101 out
