QUESTION 149
Which of the following statements are false about direct TCP offload engine (DTOE) 1.0?
A. High latency overhead still exists using the technology, such as kernel mode interrupts, locks, system calls, and thread switching.
B. This technology uses the poling mode, reducing the latency.
C. This technology requires CPU to process each MAC frame, which will consume a large number of CPU resources.
D. This technology allows to directly operate the hardware queue in the user mode, avoiding the context switching overhead.

QUESTION 150
When delivering Huawei all-flash projects, Huawei engineers introduced the Hyper CDP feature of flash storage to customers. Which of the following statements are true about this feature?
A. Copies created using HyperCDP can be used for data analysis and application testing.
B. When an application server sends a request to write data to the source LUN after a Hyper CDP snapshot is created, the storage system uses the copy-on-write (cow) technology to save the new data to a new location in the storage pool and directs the source LUN’s pointer to the new location.
C. HyperCDP is a high-density snapshot and requires the system to construct file system objects. Therefore, the system memory usage is high.
D. HyperCDP snapshots cannot be directly mapped to hosts. To read data from a HyperCDP snapshot due to actual service requirements, the administrator needs to share the file system with the host so that the host can read the source file system data at the point in time when the HyperCDP snapshot was created.
Correct Answer: AD
