1 | Is reliable delivery required by all applications? |
Answer: | No. |
2 | Does UDP provide segmentation/reassembly services? |
Answer: | No. |
3 | What is the purpose of the Destination Port field in the UDP packet header? |
Answer: | It enables the receiving host to properly route incoming packets to the appropriate Session Layer protocol. |
4 | Does UDP provide notification of dropped packets? |
Answer: | Notification is optional and is supported only in certain situations. |
5 | Is the segmentation process controlled by TCP or the ULP? |
Answer: | TCP performs segmentation and controls the process. |
6 | Why is the TCP flow-control mechanism called a sliding window? |
Answer: | Because the advertised receive buffer size is allowed to fluctuate dynamically. |
7 | What is the formula for calculating the bandwidth-delay product? |
Answer: | Bandwidth * Round-Trip Time (RTT) |
| |
8 | Does TCP guarantee in-order delivery? |
| |
Answer: | Yes. |
9 | What is the purpose of the TCP ISN? |
Answer: | To synchronize the data byte counter in the responding host's TCB with the data byte counter in the initiating host's TCB. |
10 | Is the segmentation process controlled by FC-2 or the ULP? |
| |
Answer: | FC-2 performs segmentation, but the ULP controls the process. |
11 | Which two fields in the PLOGI ELS facilitate negotiation of end-to-end delivery mechanisms in modern FC-SANs? |
Answer: | The Common Service Parameters field and the Class 3 Service Parameters field. |
12 | How is the missing frame error recovery behavior of an FC node determined? |
Answer: | The Exchange Error Policy is specified by the Exchange originator on a per-Exchange basis via the Abort Sequence Condition bits of the F_CTL field of the FC header of the first frame of each new Exchange. |
13 | After completing PLOGI with the switch, what does each initiator N_Port do? |
Answer: | Each initiator N_Port queries the FCNS and then performs PLOGI with each target N_Port discovered via the FCNS. |
