Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding IGMP (Internet Group Management Protocol):
* IGMP is used in multicast networking to manage membership of devices in multicast groups.
* Key parameters in the configuration provided:
* Interface IP Address: 192.168.1.1
* IGMP Version: 2
* Query Interval (Configured): 60 seconds
* Maximum Query Response Time: 10 seconds
* Querier Address: 192.168.1.1
2. Analysis of Each Statement:
Option A: The IP address of the interface is 192.168.1.1.
* Correct (True Statement).
* The configuration clearly shows that the IP address of the interface is 192.168.1.1.
Option B: The maximum response time to Query messages is 10s.
* Correct (True Statement).
* The configuration explicitly mentions: Value of maximum query response time for IGMP: 10 s.
Option C: The interval for sending Group-Specific Query messages is 60s.
* Incorrect (False Statement).
* The 60-second value refers to the query interval, which is the time interval between general queries sent by the querier.
* The interval for group-specific queries is not specified in this configuration. It is determined dynamically based on the multicast environment and is usually shorter than the general query interval.
Option D: The IGMP version is IGMPv2.
* Correct (True Statement).
* The configuration specifies: Current IGMP version is 2.
3. Why Option C is False:
* The 60-second value is for general query interval, not group-specific query interval.
* The statement misinterprets the configuration, making it false.
4. Summary:
* Correct Answer C (The interval for sending Group-Specific Query messages is 60s).
