Question No: 75

After verifying the initial network interfaces, which task does Exalogic Configuration Utility perform?

1. Set up passwordless SSH access for compute nodes

2. Distribute data to compute nodes

3. Copy all node-specific scripts to compute node

4. Verify passwordless SSH access for compute nodes

Answer: A

Question No: 76

How are cluster-level session replication enhacements enabled?

1. It is not necessary to configure these optimizations explicitly as the software is intelligent enough to detect the type it is executing on.

2. You create a new outbound enabled T3 network channel with SDP protocol enabled and this channel is then used as the replication channel.

3. You must set the -Dweblogic.replicationChannel=SDP system property in startWebLogic.sh

4. You must set the -Dweblogic.replicationChannel=InfiniBand system property in startWebLogic.sh

Answer: B

Question No: 77
