Oracle 12cR1 Flex Cluster introduces a new topology, which allows for a higher level of scalability. Which four statements accurately describe the new topology's properties?

• A. Hub and Leaf topologies allow tightly and loosely coupled server membership
• B. Hub and Leaf topologies supportimplicit Server Pools.
• C. Hub servers do not support Oracle ASM.
• D. Leaf servers arelight-weight, no shared storage, no peer-to-peer communication and dedicatedtoapplication service.
• E. Leaf servers are standard as in previousversions.
• F. Oracle Flex Cluster 12cR1 supports bare metal and OVM serversincommon cluster

You are building a new 12c cluster to accommodate the upcoming projects.You arecurrently working with the networkadmin team to define the requirementsneeded. Currently, thenetworkteam wouldlike to get cleared on the protocols beingused by the various network interface needed. Which three statements about Clusterware communication are correct?

• A. For the publicnetwork, each network adapter needs tosupport only UDP, which provides lowlatency.This requirement holds true for both MicrosoftWindows and Linux/Unixenvironments
• B. For the public network, each network adapter must support TCP/IP. This requirement holds true for both Microsoft Windows and Linux/Unix environments
• C. For the private network,thenetworkadapters must use high-speed network adapters and switches that support TCP/IP. This requirement holds true inthe Microsoft Windows environment
• D. There is no mandatory requirement for the protocol being supported for bothprivate and public interfaces.Oracle RAC andClusterware aulomatically detect and support any current standard industry protocol
• E. For the private network, the interface must support the user datagram protocol (UDP) using high speed network adapters and switches that support TCP/IP. This holds true inthe Linux/Unix environment.

The customeris stillnot convinced about the advantages ofusing node VIPs.Whichis the most importantpoint that willconvince him about why VIPs are usedinOracle RAC 12cR1environments?

• A. Itis needed as whenever the node/interface/network related to the VIP fails, nothing happens and node VIP never fails to any other node and stays stable
• B. Thisis needed as whenever a node/interface/network related to the node VIP fails,clients that attempt to connect to the VIP address receive a rapid connection-refused errorinstead of waiting for TCP connecttimeout messages.This helps for a quicker failure detection and resolution
• C. Itisvery convenient as whenever a node/interface/network related to the node VIPfails,the VIP can fail to another node and the failed over VIP can start accepting connections from the new node avoiding connection failures
• D. Configuring VIP is optional and not neededinan Oracle RAC 12cR1 configuration.

You want to change an existingOracle Clusterware standard Cluster to an Oracle Flex Cluster Thereis Grid Naming Service (GNS) and Flex ASM configured right now.In what order do you need to take the following steps?
1.StopOracle Clusterware 2.Determine the current mode of thecluster 3.Ensure that the GNSisconfigured with a fixed VIP. 4.Change the mode of the cluster to be an Oracle Flex Cluster. 5.Use theOracle Automatic Storage Management Configuration Assistant (ASMCA) to
enable Oracle Flex ASMinthe cluster 6.Start Oracle Clusterware
