Nokia Certified Network Associate – SR OS Network Administration — Question 21

A routed-VPLS is connected to an IES interface. The VPLS service MTU is 1400 bytes and the IES interface IP-MTU is 1500 bytes. Which of the following statements is TRUE?

Answer options

• A. Any IP packet larger than 1386 bytes will be fragmented.
• B. Any IP packet larger than 1400 bytes will be fragmented.
• C. Any IP packet larger than 1414 bytes will be fragmented.
• D. Any IP packet larger than 1500 bytes will be fragmented.

Correct answer: B

Explanation

The correct answer is B because the VPLS service MTU of 1400 bytes dictates the maximum size of packets that can be transmitted without fragmentation. Any packet exceeding this size will require fragmentation. The other options incorrectly reference sizes that do not align with the established MTU limits.
