A 1500 byte MTU has 8 bytes of Preamble and SOF. It also has 4 bytes of FCS, this makes 1512 bytes for the full frame. In CSMA/CD environments, there is a requirement of 8 bytes of silence between the end of one frame and the start of the next. This is 1520 bytes. Correct answer is C.
if default MTU size is 1500… everything above 1500 can cause an Error.
For me even anything above MTU 1472 causes an error. ping -f -l 1472 ip
C correct. 100% sure
C is correct! this is explanation: http://www.cisco.com/c/en/us/support/docs/switches/catalyst-4000-series-switches/29805-175.html

NEW QUESTION 297
Which two VLANs are reserved for system use only? (Choose two.)
A. 1
B. 4095
C. 4096
D. 0
E. 1001
Answer: BD
Explanation:
The VLANs 0 and 4095 are reserved by the IEEE 802.1Q standard and you cannot create, delete, or modify them so they are the correct answers.
Note:
– VLAN 0 and 4095 are reserved for system use only. You cannot see or use these VLANs.
– VLAN 1 and VLANs 1002-1005 are default VLANs. Default VLANs are created automatically and cannot be configured or deleted by users.
– VLAN 2 to 1001 are normal VLANs. You can create, use and delete them.
– VLAN 1002 to 1005 are normal VLANs too but Cisco reserved for FDDI an Token Ring.

standard frame is 1500 bytes. Baby Jumbo Frames are anything SLIGHTLY larger than 1500, up to 1600 bytes. Jumbo Frames are between 1600 and 9000 bytes. Super Jumbo frames are lager than 9000 bytes of payload. So, to answer this question: Just look at which MTU setting is slightly larger than 1500 MTUs, and that would be D) 1518
standard MTU is 1500, which causes the payload size to be 1518 (because of 18byte header + CRC) which is standard (up to 1522 when using 802.1q for vlan tagging). so 1500 would be fine = 1518 payload. 1600 would cause ~1618 payload (not a baby giant). 1518 would become ~ 1536 which is within baby giant range and would likely cause an error if the receiving end is not configured for this frame size (which it likely isnt). im not sure what error would be thrown for a 1618 sized payload, but according to most sources baby giants < 1601 so i imagine it wouldnt be a baby giant error.
best answer is D
This is a tricky question. It says what MTU causes a baby giant and not what Ethernet frame size. If the MTU is 1518 and we add another 18 for header and CRC, it will give us a total of 1536 bytes which is a baby giant. On the other hand, if the MTU is 1600, then the Ethernet frame size would be 1618 bytes which is already considered a jumbo?
See explanation here https://www.cisco.com/c/en/us/support/docs/switches/catalyst-4000-series-switches/29805-175.html
Standard Ethernet frame MTU is 1500 bytes. This does not include the Ethernet header and Cyclic Redundancy Check (CRC) trailer, which is 18 bytes in length, to make the total Ethernet frame size of 1518. In this document, MTU size or packet size refers only to Ethernet payload. Ethernet frame size refers to the whole Ethernet frame, including the header and the trailer. Baby giant frames refer to Ethernet frame size up to 1600 bytes, and jumbo frame refers to Ethernet frame size up to 9216 bytes.
Hi all,
Passed my exam today (barely… 841/832)… this question was on it.
Dec 4, 2017
I honestly had no idea what it was but made the best guess at 518..and i was right. so… that’s good, lol.
