   A company has 300 users and a single public IP address. They currently use PAT with the interface address. Users are experiencing slow internet and some connections fail. The administrator suspects PAT port exhaustion. Which solution would best alleviate the issue without changing the ISP-assigned address?

   • AIncrease the NAT translation timeout to keep translations active longer.
   • BConfigure static NAT for the most active users.
   • CUse dynamic NAT without overload to spread connections across multiple addresses.
   • DAdd a second public IP address to the outside interface and use a NAT pool with overload.

   A company has 50 internal hosts that need to access the internet. The ISP has assigned a block of 10 public IP addresses (203.0.113.10–203.0.113.19). The administrator wants to allow all internal hosts to share these addresses dynamically, but only when they initiate outbound traffic. Which configuration is required?

   • ADefine a NAT pool and apply 'ip nat inside source pool <pool> overload' without an access list.
   • BConfigure 'ip nat inside source list 1 pool PUBLIC' and then assign the pool addresses to the inside interface.
   • CCreate an access list matching internal hosts, define a NAT pool with the public addresses, and apply 'ip nat inside source list <acl> pool <pool>' on the inside and outside interfaces.
   • DApply 'ip nat inside source static 203.0.113.10 203.0.113.19' to map the entire pool to one host.
