Which two number ranges are used to identify extended ACLs? (Choose two.)
- 100 - 199
- 2000 - 2699
- 1 - 99
- 1300 – 1999
- 101 - 200
- 1 - 100
Explanation: Cisco IOS uses specific number ranges to distinguish between different types of Access Control Lists (ACLs). Numbered extended IPv4 ACLs are identified by the range 100 to 199. For larger configurations, an expanded range of 2000 to 2699 is also reserved for extended ACLs.
These specific ranges instruct the router to accept extended ACL statements, which allow for more granular filtering by testing source and destination addresses, protocols, and port numbers. In contrast, the ranges 1 to 99 and 1300 to 1999 are reserved exclusively for standard IPv4 ACLs.
