Passleader has this question twice. First question has the answer same as given here, the 2nd Q has the answer as A+E (payload + reduce CPU overhead)...
If this is on the test I am going with A+E.
Do jumbo frames increase bandwidth?
Jumbo frames can also boost receive throughput by up to 40 percent, allowing a single virtual machine to receive traffic at rates up to 5.7Gbps.
One of the biggest issues with networking is that data of various sizes is
crammed into packets and sent across the medium. Each time this is done,
headers are created (more data to process), along with any filler needed, creating
additional overhead. To get around this, the concept of jumbo frames is used to
allow for very large Ethernet frames; by sending a lot of data at once, the
number of packets is reduced, and the data sent is less processor intensive
Why use jumbo frames?
The obvious advantage of using jumbo frames is more data is transferred in less packets. This means less protocol overhead, e.g., if one ACK were sent every 8 packets, that ACK is now acknowledging 72,000 bytes of data vs 12,000 bytes of data. This results in less network chatter.
Let’s assume we need to transfer 20 gigabytes (21,474,836,480 bytes) of data as quickly as possible. With a standard 1500 byte MTU that will take 14,316,558 packets, but with an MTU of 9000 we are sending 2,386,093 packets. That’s a difference of 11,930,465 packets.
That’s our advantage. Speed when sending large amounts of data.
I disagree. I think A and B are correct. Jumbo frames increase bandwidth since each frame carries more data per frame header, as there is more data per frame than a normal frame.

In this same page wikipedia said: "Jumbo frames have the potential to reduce overheads and CPU cycles[5]". Can you use more efficiently you bandwidth with jumboframes enabled? sure, but jumboframes can't increase your bandwitdh. So I think A and E.
