In the Cluster Communication Architecture Employed by an N8500 Clustered

question 14

Multiple Choice

In the cluster communication architecture employed by an N8500 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.

Definitions:

Genes

Genes are units of heredity made up of DNA. They carry the information responsible for the development of organisms.

Carriers

Individuals who have one copy of a gene for a recessive trait and can pass that gene to their offspring, even if they do not exhibit the trait themselves.

Recessive Genes

Genes that are not dominant and can be masked by the presence of dominant genes, requiring two copies, one from each parent, for the trait to be expressed.

Meiosis

The form of cell division in which each pair of chromosomes splits and one member of each pair moves to the new cell. As a result, each new cell has 23 chromosomes.
