Explanation

NAT Configuration Explanation

In a standard NAT pool configuration, the inside local addresses (private, untranslated) are defined by the ACL or source network - typically the 10.1.1.0/27 subnet - and these are translated to the inside global addresses from the NAT pool, which is the 209.165.201.0/27 subnet. This confirms A (inside source addresses are translated to 209.165.201.0/27) and E (10.1.1.0/27 is the inside local address range) as correct.

Why the distractors are wrong:

• B is incorrect because a NAT pool with an ACL performs dynamic NAT (many-to-many), not one-to-one static NAT
• C is wrong because 10.1.1.0/27 is the inside local range, not the inside global range - the pool (209.165.201.0/27) serves as the inside global addresses
• D is incorrect because 209.165.201.0/27 is the inside global address pool, not the outside local range; outside local/global addresses refer to the destination, not the source

Memory Tip: Use the NAT address table: Inside Local → Inside Global (your private IPs get translated to the pool). "Local = original, Global = translated" - the ACL defines local, the pool defines global.
