Question 51

Organizations are sometimes faced with the need to locate cluster members in different geographic locations that are distant from each other. A typical example is replicated data centers whose location is widely separated for disaster recovery purposes. What are the restrictions of this solution?

  1. There are two restrictions: 1. The synchronization network must guarantee no more than 100ms latency and no more than 5% packet loss. 2. The synchronization network may only include switches and hubs.
  2. There is one restriction: The synchronization network must guarantee no more than 150 ms latency (ITU Standard G.114).
  3. There is one restriction: The synchronization network must guarantee no more than 100 ms latency.
  4. There are no restrictions.

Question 52

You have a High Availability ClusterXL configuration. Machines are not synchronized. What happens to connections on failover?

  1. Open connections are lost but can be reestablished.
  2. It is not possible to configure High Availability that is not synchronized.
  3. Connections cannot be established until cluster members are fully synchronized.
  4. Open connections are lost but are automatically recovered whenever the failed machine recovers.

Question 53

When using ClusterXL in Load Sharing, what is the default sharing method based on?

  1. IPs
  2. IPs, SPIs
  3. IPs, Ports
  4. IPs, Ports, SPIs

Question 54

If ClusterXL Load Sharing is enabled with state synchronization enabled, what will happen if one member goes down?

  1. The processing of all connections handled by the faulty machine is immediately taken over by the other member(s).
  2. The processing of all connections handled by the faulty machine is dropped, so all connections need to be re-established through the other machine(s).
  3. There is no state synchronization on Load Sharing, only on High Availability.
  4. The connections are dropped as Load Sharing does not support High Availability.

Question 55

What is a Sticky Connection?

  1. A Sticky Connection is one in which a reply packet returns through the same gateway as the original packet.
  2. A Sticky Connection is a connection that remains the same.
  3. A Sticky Connection is a VPN connection that remains up until you manually bring it down.
  4. A Sticky Connection is a connection that always chooses the same gateway to set up the initial connection.
