  2. Every backend server must accept packets addressed to the IP address of the virtual service.

  2. The number of nodes in a cluster has no effect on the availability as long as the sum of the available computing resources isequal.

  3. Failover clusters can be used to scale a single service beyond the capacity of a single cluster node.

  4. In regular cluster operation, not all resources are used.

  5. In case of the failure of any component, enough resources must remain to provide all cluster services.

  2. No actions are necessary as a load balancer cannot become a single point of failure.

  3. Two or more load balancers should be deployed as a cascade that passes packets from one to the other.

  4. Two load balancers should be deployed as a failover cluster.

  5. Load balancers are used for performance and scalability reasons only and cannot be used to archive high availability clusters.

Answer: D

Question No: 79 – (Topic 2)

Which of the following statements are true regarding a load balancer? (Choose TWO correct answers.)

  1. Failover clusters are not operational without at least one dedicated load balancer.

  2. All response packages sent from a backend server to a client must pass through the load balancer.

  3. The load balancer is usually deployed on one of the backend servers.

  4. Load balancers may be able to analyze traffic.

  5. All incoming connections to the cluster services are received by the load balancer.

Answer: D,E
