Why would you want to use both host firewalls and network firewalls? you would not want to use both because a network firewall will cancel out a host firewall. you would only use network firewalls as a backup after the host firewall failed. multiple layers of defense must be considered regarding access to web servers or other servers exposed to the internet. all windows operating systems come equipped with both types of firewalls installed so most enterprises simply use both of them.

Python. primary u. s. interstate highways are numbered 1-99. odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. thus, the 405 services the 5, and the 290 services the 90. given a highway number, indicate whether it is a primary or auxiliary highway. if auxiliary, indicate what primary highway it serves. also indicate if the (primary) highway runs north/south or east/west.
