Q1. Examine the output of the asmcmd and srvctl commands: 

$ asmcmd showclustermode 

ASM cluster : Flex mode enabled $ srvctl status asm –detail ASM is running on host01, 

host03 ASM is enabled. 

$ srvctl config asm 

ASM home: /u01/app/12.1.0/grid 

Password file: +DATA/orapwASM 

ASM listener: LISTENER 

ASM instance count: 2 

Cluster ASM listener: ASMNET1LSNR_ASM Then you execute this command: 

$ srvctl relocate asm – currentnode host03 –targetnode host02 

Which three statements are true regarding the execution of this command based on the 

output shown? 

A. It fails because an ASM instance is not configured to run on HOST02. 

B. It succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03. 

C. It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnectedto the ASM instance on HOST02. 

D. It fails because the ASM instance has not been shut down first on HOST03. 

E. It succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut downuntil all connected clients disconnected. 

F. It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnectedto the ASM instance on HOST01. 

Answer: C,E,F 

Q2. Which three statements are true about Oracle Enterprise Manager Topology Viewer? 

A. It displays which listeners listen on behalf of which instances. 

B. It displays the relationship between targets of different target types in a cluster. 

C. It displays the status of all cluster components. 

D. It displays the status of Pluggable Databases (PDBs) in a multitenant container database (CDB). 

E. It displays the relationship between clustered ASM and cluster databases if the database is stored in ASM. 

F. It displays the type of network used by RAC database instance. 

Answer: A,C,D

B. a cluster file system 

C. a shared NFS file system 

D. the DATA disk group 

E. a local file system with the same path name on each cluster node

B. CRM is available for new logins on one CDB1 isntance. 

C. The srvctl start service command automatically opens PDB_1 if not already opened.
