What is the benefit of bonding the client access network configuration?
A.
Improved performance
B.
Improved reliability
C.
Both improved performance and reliability
D.
A Single Client Access Name (SCAN)
E.
Improved monitoring
Explanation:
The network ports can be connected directly between the components or the ports
can be bonded
together to form a logical interface. The bonded ports can be configured for load balancing, fault
tolerance, and better network utilization

I think correct answer should be B. help?
C is the correct one as it provides Failover and Load Balancing.
B is correct answer
How do you know?
B – active/passive configuration provides fault tolerance and high availability.
c
c
it says “client access network configuration” not infiniband
The correct answer is B.
Client access network: This required network connects the database servers to your existing client network and is used for client access to the database servers. Applications access the database through this network using SCAN and Oracle RAC VIP addresses. Database servers support channel bonding to provide higher bandwidth or availability for client connections to the database. Oracle recommends channel bonding for the client access network. Channel bonding on Oracle Exadata Database Machine X2-2 bonds NET1 and NET2.
C is right.
The network port on a database server used for the client access network can be bonded with another network on the database server to provide higher bandwidth or availability for client connections to the database.
Bonding here is configured with “ACTIVE-BACKUP” configuration for client network. Due to which it provides Availability. In such configuration only one slave remains active and another becomes active only when first has failed. Hence it provides Reliability rather than Performance.
Due to above said fact option B is correct.
C is right and L. Zhu is right. The Oracle PDFs (search for text provided from L. Zhu).

B: Improve Reliability
According to “Exadata Datbase Machine Administration Workshop Student Guide – Volume 1” (D73668GC21) X3/X4 follow the explanation:
“A bonded client access network interface can provide protection if a network interface fails. However, using bonded interfaces may require additional configuration in the customer’s network.
It should be B. Although in our X4-2 we made changes and aggregated it for higher bandwidth
https://docs.oracle.com/cd/E50790_01/doc/doc.121/e51950/network.htm#DBMIN195
When channel bonding is configured for the client access network during initial configuration, the Linux bonding module is configured for active-backup mode (mode=1). If a different bonding policy is preferred, then you may reconfigure the bonding module after initial configuration. For configuration details, refer to the Linux Ethernet Bonding Driver HOWTO in the /usr/share/doc/kernel-doc-2.6.18/Documentation/networking/bonding.txt directory on any Oracle Exadata Database Machine database server.
Note:
When using a bonded network configuration, you must provide a network switch capable of supporting the chosen bonding mode. For example, if mode 4 is configured (IEEE 802.3ad Dynamic link aggregation), then you must supply and configure the network switch capable of supporting this bonding mode. Requirements for specific bonding policies are documented in the Linux Ethernet Bonding Driver HOWTO.
Go with C, the following documentation:
http://docs.oracle.com/cd/E50790_01/doc/doc.121/e51950/network.htm#sthref109
states “Database servers support channel bonding to provide higher bandwidth or availability for client connections to the database.”
For my knowledge i will go fo C both improved performance and reliability.
