While a system administrator is checking the TCP/IP connectivity between two systems with the traceroute command, the administrator found Fragmentation required messages in the traceroute output.
What is the likely reason for these messages?
Correct : C
The source system is using Jumbo Frames and the target is using the default MTU size. Fragmentation required messages can appear in traceroute output when the Maximum Transmission Unit (MTU) size of the source and target systems are different. In this case, the source system is using a larger MTU size (Jumbo Frames) than the target system (default MTU size). As a result, the router gateway must fragment the data packets in order for them to reach their destination. This is why the fragmentation required messages appear in the traceroute output.

Which logical volume Mirror Write Consistency policy should an AIX V7.2 administrator use to achieve the data consistency between mirrors?
Correct : C
The superstrict mirror write consistency policy is the most reliable policy for achieving data consistency between mirrors in AIX V7.2. This policy will maintain the data consistency between mirrors by writing the data to both mirrors before the write operation is acknowledged as complete.
