Which two types of IP addresses does Oracle Clusterware 12c acquire from DHCP when it started up on a cluster node using Grid Naming Service (GNS)? (Choose two.)
A.
Single Client Access Name (SCAN) virtual IP addresses (VIPs)
B.
Grid Naming Service (GNS) VIPs
C.
ASM Listener VIPs
D.
High Available IP (HAIP) addresses uses for the cluster interconnect
E.
Intelligent Platform Management Interface (IPMI) IP addresses
Correct: A, C
Wrong B – To use GNS, you must specify a static IP address for the GNS VIP address
Wrong E – IPMI is optional
Could you explain about ASM lister VIPs? I’ve never read about it before…
@jipenlee
“ASM listener vips” I understood as simply node-VIP.
At node-vip local listener listen for RDBMS & GI connections. You can use e.g. asmcmd to copy files beetwen two ASM instances over network.
Look at table 5-1 (5.11): https://docs.oracle.com/database/121/CWLIN/networks.htm#CWLIN473
Node VIPs and SCAN require DHCP in GNS option. There is nothing about IPMI configuration.
But yes, IPMI IP addresses CAN be acquire from DHCP, so the correct answer shoud be:
A, C – if we accept ‘asm listener’ as GI listener (SCAN and GI-vips shoud assign address from DHCP)
A, E – if not. We can configure IPMI to use dhcp, but this is optional, not mandatory.
Yes, I understood your point, I will go for A,E
Correct A,E
To support dynamic IP address assignment for IPMI using DHCP, the Cluster Synchronization Services daemon requires direct communication with the local IPMI device during Cluster Synchronization Services startup to obtain the IP address of the IPMI device. (This is not true for HP-UX and Solaris platforms, however, which require that the IPMI device be assigned a static IP address.) This is accomplished using an IPMI probe command (OSD), which communicates with the IPMI device through an IPMI driver, which you must install on each cluster system.

No Never, GNS have to be static IP, it can’t be obtained from DHCP…

The GNS virtual IP address is a static IP address configured in the DNS.
