Exam 11: HCIE-Storage

An MSCS Two-Node Cluster Interconnects with Disk Arrays via the iSCSI Protocol in a Multipathing Environment and Multipathing Software installed on Each Node. You build the cluster configuration using the wizard and part of the description shows that the quorum disk and resource disk can not be online. The following statement is correct regarding this scenario:

After the smart migration configuration is complete, you add the LUN ID and data volume ID of the source LUN at the start of the migration to 1 and 2 respectively, and specify the LUN ID of the target LUN.  And data volume ID named 3 and 4. When the migration is complete, the LUN ID and data volume ID of the source LUN and the target LUN are:

Which of the following is a description of the WORM feature of OceanStor V3: (Multiple choice)

Info Replicator supports copying the data at the same time, the basic attributes of the home directory, extended attributes, ACL (access control list). WORM (write-once-read-many) and CIFS / NFS share configuration information is also a wealth island from the end. When a disaster occurs, master and slave sites can quickly take over the business after the switch.

In a Huawei N8500 cluster system VCS Error information is stored in which of the following log files? (Multiple choice)

Huawei OceanStor storage controller BBUs are both in a fault alarm. Which description is correct for the upper application?

WMware backup transfer mode NBD SSL refers to the backup agent through the TCP / IP network to read the backup data, VSA and ESX between encrypted transmission.

A bank using the Oceanstor 9000 (v100R001) has officially started on-line operation and into the maintenance phase, maintenance engineer Zhang will be responsible for this. During the maintenance work, the need for periodic inspection of the health of the storage system, which of the following is the method of operation Zhang should. (Multiple choice)

The peak write bandwidth for an application is 10MB / S, with an average write latency of 200KB / s and an average write IO size of 4KB (bandwidth utilization of 70%). If you need to use OceanStor V3 storage array to implement data disaster recovery and set it as asynchronous replication mode, you need the minimum network-wide bandwidth:

The MTTR indicator is used to describe the average continuous time of the failure of a product during operational use or testing.

The CIFS share cifs_share_001 is configured through the OceanStor deviceManager management interface of OceanStor 9000, and the configured share properties are as follows: (1) share named cifs_dir_001 (2) read-only access (3) Using local authentication user mode, user name cifsuser001, password Password @ 123; One of the front-end IP addresses of the OceanStor 9000 storage system is 96.69.35.7. Which of the following descriptions is correct?

in an OceanStor V3 series storage array, all the snapshots of a LUN occupy not more space than that of the LUN.

In the Huawei OceanStor system, the size of the file system block is a measure of the size of the accessed file system block. The size of the block is designed according to the size of the data block. Different size of the file system block selects the corresponding file system block, according to the size of the data block. If the business scenario is the media, for large file archiving or stagger I / O backup scenarios, it is recommended to choose the default 64KB disk block size.

Which Huawei OceanStor V3 storage system prefetch strategy is correct?

N8000 clustered NAS system to provide file system sharing services, surface VxFS file system and roll features the correct statement:

Client server resources are limited but there is sufficient network bandwidth.  What kind of deduplication strategy should be used if the client data needs to be backed up to the physical tape?

In a Huawei OceanStor 9000 V100R001C30, in order to experiment with the video surveillance functions of multiple Huawei OceanStor 9000 product you need to install UniformView software.  Which of the following statements is wrong?

Client A is installed on the Oracle client, and now it has to visit the remote database host B. What should you modify on the host A or B for this? (Multiple choice)

Which technology enhances performance of Huawei OceanStor 9000 application? (Multiple choice.)

In a clustered environment, data is placed on the shared storage, and identities between peers are equal and have the same access to the data. It is required that the clusterware have a control mechanism for concurrent access to such peer permissions. In Oracle RAC, you use the _____ mechanism to do multiple node-to-node collisions control of access.
