The WORM feature adds WORM attributes to the ordinary file system, so that files in the file system can only be read but not written.
- A . True
- B . False
A company deployed a set of Huawei all-flash storage, and the host business accessed the storage through multiple Ethernet links. The operation and maintenance engineer found that when the Ethernet port used for the front-end business of the storage failed, the host business would be interrupted.
Which of the following planning items would not have avoided the problem in the scenario?
- A . Planning VLAN-based IP drift
- B . Planning IP drift based on bound ports
- C . Planning IP drift based on logical ports
- D . Planning IP drift based on Ethernet ports
In order to ensure business continuity, a securities company plans to establish a disaster recovery architecture with three centers in two locations. The purpose is to ensure that when a disaster such as a circuit failure or fire occurs in the production center, the business can be quickly switched in the disaster recovery center to maximize the protection of the continuous operation of the business system.
Currently, the company has deployed production data centers, disaster recovery centers in the same city, and disaster recovery centers in different locations. The general situation is as follows:
(1) Production center in location A: Windows/Linux operating system, database, etc.
(2) Disaster recovery center in location A: 100 km from the production center;
(3) C remote disaster recovery center: 1000 km away from the production center.
The customer requires that the RPO between data centers in the same city is 0, RTO is 0, and the remote disaster recovery center is used as a data-level disaster recovery center, and the data recovery RPO is less than 10 minutes.
Which of the following descriptions of the project’s construction of two locations and three centers are correct? (Multiple choice)
- A . Because the customer requires RPO < 10 minutes, the primary data LUN can be initially synchronized to the secondary LUN in full, and then synchronized to the secondary LUN periodically.
- B . WDM equipment needs to be deployed between data centers in the same city
- C . The storage capacity and LUN configuration planning of the disaster recovery center in the same city should be kept consistent with that of the production center to provide better dual-active performance.
- D . To meet customer RPO and RTO requirements, the three data centers need to adopt a parallel replication (synchronous + synchronous) architecture
A company implements continuous data protection for the file system of important applications. When it is necessary to roll back the file system snapshot, the application shared mount of the source file system must be canceled.
- A . True
- B . False
When BCManager creates a protection group and sets protection for a LUN, the LUN cannot be viewed on the interface. What could be the reason? (Multiple choice)
- A . There is a problem with the remote replication configuration
- B . Storage initiator configuration
- C . There is a problem with the storage LUN configuration
- D . There is a problem with the BCManager software configuration
Fault analysis, also known as fault diagnosis, is the process of collecting and analyzing data in order to determine the cause of a fault and how to prevent it from happening again.
- A . True
- B . False
In the 3DC solution of active-active + remote replication, active-active + integrated backup, and ring 3DC solution (active-active + asynchronous replication), there is no concept of disaster recovery center in the same city. The two data centers of active-active can provide services to the outside world at the same time.
- A . True
- B . False
Which of the following options are correct regarding backup strategy planning principles? (Multiple choice)
- A . Use incremental backup to shorten backup time or reduce backup bandwidth
- B . Avoid performing backups during periods of large backup data flows.
- C . If there are a large number of small files, it is recommended to use volume backup
- D . Avoid peak business hours
