Identify two permitted uses of external InfiniBand connections to a Database Machine.
A.
To connect an ExaLogicElastic CloudMachine
B.
To monitor the InfiniBand network using Enterprise Manager
C.
To connect an external tape library
D.
To use a bonded client access network
E.
To use a bonded management network
Explanation:
A:Combining the Oracle Exalogic Elastic Cloud withthe Oracle Exadata Database
Machine for SAPNetWeaver
The InfiniBand fabric that spans Exalogic and Exadata
components provides the following key ways of
simplifying and accelerating SAP NetWeaver installations running on Exalogic
Note:A highspecialized database networking protocols connects all the components inside
anExadata Database Machine. External connectivity to the Exadata Database Machineis provided
through standard 1 Gigabit and 10 GigabMultiple X3even larger configurations.
Instead of B it should be C.
External Tape Library through Infiniband isn’t supported, only Backup Appliance is supported through Infiniband – hence C option is obsolete.
C is correct.
The correct answer is A & C. External tape library is supported connected to Infiniband.
Miles is right! Infiniband external connectivity ports can be used for media servers for tape backup. So correct ones will be A & C.
A, C
I agree with Manish Nashikkar. IB external connectivity can be between DM and Media Servers or Backup Appliance, can’t between DM and Tape Library.

A is right. ExaLogic and Exadata can be connected via InfinitBand
B is wrong. You do not need to have external IB connection to monitor IB
C is right. You use IB connection for fast backup/restore with tape library
D is wrong. IB is internal, private interconnect
E is wrong.
So A. C. are correct.
