An N8500 clustered NAS system is equipped with six engine nodes and four S5500T storage arrays. Each engine node provides eight service network ports. How many IP addresses must be configured for the N8500?
A. 103
B. 104
C. 105
D. 106
If the internal link is faulty in an N8500 clustered NAS storage system, which of the following items can be skipped during troubleshooting?
A. The heartbeat network between engines
B. The network between an engine and a disk enclosure
C. The Fibre Channel network between an engine and a storage unit
D. The network between a storage unit controller enclosure and a storage unit disk enclosure
Which of the following statements about the Global Cache technology employed by the WushanFS are correct? (Select three.)
A. Global Cache enables the memory space on all storage servers to form a unified memory resources pool logically.
B. Data cached on a node cannot be hit by the read/write service of another node.
C. Global Cache helps improve the sharing of memory resources among nodes.
D. The WushanFS uses the distributed lock mechanism to implement global management of cached data. The same service data is cached only on one node. Another node that needs to access the service data can apply for a lock to obtain the cached data.
Which of the following statements about the characteristics of the file system snapshot feature provided by an N8500 clustered NAS system are incorrect? (Select two.)
A. A snapshot and the file system each use independent storage space to ensure data reliability.
B. A file system snapshot is a view identical with the file system.
C. File system snapshots are readable, writable, and independent of the file system.
D. You can create multiple snapshots for a file system. However, you cannot create a snapshot for an existing snapshot.
In the cluster communication architecture employed by an NS500 clustered NAS system, modules such as the resource agent, HAD, GAB, and Low Latency Transport (LLT) must collaborate to implement cluster communication. Which of the following statements about the work mechanisms of these modules are correct? (Select three)
A. The agent monitors the resources of each system and provides the status information for the HAD of each machine.
B. If a cluster node is abnormal or faulty, the HAD takes correct actions, for example, performing a failover.
C. The GAB implements a point-to-point communication mechanism. The master node sends the other cluster nodes the information that needs to be synchronized.
D. LLT is a MAC-layer protocol unrelated to IP layer.
Which are the characteristics of the OceanStor 9000 M node? (Select two.)
A. 2U
B. Up to 12 service disk slots
C. Applicable to scenarios requiring large capacity
D. Standard configuration:2 x 6-core CPUs
Which of the following service ports are provided by an N8500 clustered NAS system? (Select two.)
A. GE
B. 10GE
C. Fibre Channel
D. SAS
Which of the following components comprise the Storage Foundation of an N8500 clustered NASsystem? (Select two)
A. VxVM
B. VCS
C. VxFS
D. SFS
InfiniBand is used for communication between servers, between a server and a storage device, and between a server and a network.
A. True
B. False
Which of the following statements about the InfoLink feature of the OceanStor 9000 are correct? (Select two.)
A. If clients attempt to access the OceanStor 9000 using domain names, the InfoLink license must be activated.
B. If clients attempt to access the OceanStor 9000 using domain names, a DNS server must be configured.
C. If a node becomes faulty, the system provides the failover function. This function does not need the InfoLink license to be activated.
D. After the InfoLink license is activated, the system balances loads based on round robin, CPU usage, number of node connections, node throughput, and comprehensive node loads.
