Which two statements are true concerning Oracle Enterprise Manager Cloud Control Cluster Database performance pages? (Choose two.)
A.
The Interconnects page shows the load contributed by database instances on the public network.
B.
The Interconnects page shows the load contributed by database instances on the private interconnect and the public network.
C.
The Interconnects page shows throughput contributed by individual sessions on the private interconnect.
D.
The Cluster Cache Coherency page shows which block classes are subject to intense global cache activity.
E.
The Cluster Cache Coherency page shows which instances are responsible for intense global cache activity.
D,E
I can’t find “Interconnects page”.
Correct B,D
B:
The Cluster Interconnects page helps determine the load added by individual instances and databases on the interconnect. Sometimes you can immediately identify interconnect delays that are due to applications outside Oracle.
You can use this page, shown in the following figure, to perform the following tasks:
View all interfaces that are configured across the cluster.
View statistics for the interfaces, such as absolute transfer rates and errors.
Determine the type of interfaces, such as private or public.
Determine whether the instance is using a public or private network.
Determine which database instance is currently using which interface.
Determine how much the instance is contributing to the transfer rate on the interface.
D:
Accessing the Cluster Cache Coherency Page
The Cluster Cache Coherency page contains summary charts for cache coherency metrics for the cluster.

You can use the Oracle Enterprise Manager Interconnects page to monitor the Oracle
Clusterware environment. The Interconnects page shows the public and private interfaces on
the cluster, the overall throughput on the private interconnect, individual throughput on each
of the network interfaces, error rates (if any), and the load contributed by database instances
on the interconnect.
I think D & E agree

I will go to B,D
E wrong
Cluster Cache Coherency page as per my understanding does not show instance related information, just block info (even in the image https://docs.oracle.com/database/121/TDPRC/img/GUID-06F9BD1E-CEC7-471F-B6BD-D204A32CFE3E-default.gif)
https://docs.oracle.com/database/121/TDPRC/racmon2.htm#TDPRC335
B right
so the other best option is this one
