H13-624_V5.5 Practice Questions

A.  

Generally, the low watermark for storing dirty data in the cache should not be too low. The recommended value is 20%.

B.  

Generally, the high watermark of the cache should not be too high, and the difference between the high and low watermarks should not be too small.

C.  

If the high watermark of the cache is too high, I/O fluctuation and latency increase will occur usually when the current I/O traffic bursts.

D.  

If the high watermark of the cache is too high, the write performance will be affected. If the low watermark of the cache is too low, the read performance will be affected.

A.  

The running status of the HyperMetro pair is "Normal". The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B continues providing services.

B.  

The running status of the HyperMetro pair is "To be synchronized". The arbitration result is that the volume in equipment room A continues providing services and that in equipment room B stops providing services.

C.  

The running status of the HyperMetro pair is "Normal". The arbitration result is that the volumes in equipment rooms A and B continue providing services.

D.  

The running status of the HyperMetro pair is "To be synchronized". The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B stops providing services.

A.  

This technology uses digital signatures to verify firmware integrity and prevent firmware and operating systems from being tampered with.

B.  

After a device is powered on, the initial startup module starts, and verification is performed level by level. If the verification is successful, the device starts.

C.  

During secure boot, the RSA engine verifies the status of the software signature certificate and then verifies the Grub signature public key.

D.  

In the overall startup process, Grub needs to be verified and loaded first. After the loading is complete, the Grub signature public key is verified.

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.

A.  

Post-process compression means that data is first written to storage media and then read for compression.

B.  

During inline deduplication, the system divides data into blocks and then calculates fingerprints for the blocks.

C.  

During similarity-based deduplication in the background, the system does not divide data into blocks and can directly calculate similar fingerprints.

D.  

Backup storage supports deduplication and compression of file systems.
