HCIP-Storage V5.5 H13-624_V5.5 Exam Questions with Experts Answers Updated Recently

A.  

This technology requires CPU to process each MAC frame, which will consume a large number of CPU resources.

B.  

This technology allows to directly operate the hardware queue in the user mode, avoiding the context switching overhead.

C.  

This technology uses the polling mode, reducing the latency.

D.  

High latency overhead still exists using the technology, such as kernel mode interrupts, locks, system calls, and thread switching.

A.  

TRUE

B.  

FALSE

A.  

The protocol layer is responsible for protocol parsing and permission management. SAN and NAS are two sets of semantic logic. Therefore, different service entry components are used.

B.  

The space management layer uses the active-active high reliability mode to provide reliable data protection capabilities based on actual service scenarios of customers.

C.  

The software architecture consists of the following layers from top to bottom: protocol, data service, cache, file and block space management, and storage pool.

D.  

At the protocol layer, NFS/CIFS supports direct TCP offload engine (DT06), while ISCSI does not.

A.  

In the information collection phase, the engineer needs to collect basic information about applications and data, such as the impact of application configurations on data, data size, and read/write ratio.

B.  

In the test and application phase, the engineer needs to test the configurations to check whether the optimization objective is achieved. If yes, the engineer can put the system into use.

C.  

In the optimization analysis phase, the engineer needs to specify the performance optimization objective, find out the performance bottleneck, and identify the parts that play a key role in Improving the system performance.

D.  

In the optimization operation phase, the engineer needs to deploy DR for the service system, and needs to modify multiple configuration at a time during the optimization configuration.
