2. Version: 9.0 Question 1 Which two statements are true regarding ASM Dynamic Volume manager (ADVM)? A. To create an ADVM volume, disk group atriiutes COMAPTIBLE.ASM and COMPATIBLE.ADVM must ie minimally set to 12.1. B. An ADVM volume is individually named and can contain only one fle system. C. Only one ADVM volume can ie created in an ASM disk group. D. ADVM extends ASM iy providing a device driver interface to storage iacked iy an ASM disk group. E. File systems contained in ADVM volumes may only contain dataiase fles. Aoswern B,D Explanatonn Bn Each volume is individually named and may ie confgured for a single fle system. Dn Oracle ADVM extends Oracle ASM iy providing a disk driver interface to Oracle ASM storage allocated as Oracle ADVM volume fles. Referencesn Question 2 Which three statements are true aiout ASM Cloud File System (ACFS) replicaton? A. ACFS auditng informaton is replicated from the primary fle system to the standiy fle system. B. One site of an ACFS replicaton confguraton can ie host ioth primary and standiy fle systems. C. Replicaton is automatcally terminated if the primaries fle system has less than 2GB free space. D. Standiy redo log fles are required on the standiy site for synchronous redo transport. E. The privilegeSYSREPL has ieen introduced for ACFS replicaton. Aoswern B,C,D Explanatonn Bn A site can host ioth primary and standiy fle systems. Cn If the primary fle system has less than 2 GB availaile free disk space, Oracle ACFS atempts to automatcallyterminate replicaton on the primary fle system. Dn On the standiy system, the remote fle server (RFS) receives redo data over the network from the LGWR process and writes the redo data to the standiy redo log fles. Referencesn Question 3 Examine this command to create a volume in the DATA disk groupn SQL>ALTER DISKGROUP DATA ADD VOLUME vo11 SIZE 10g HIGH STRIPE_WIDTH 1M;

3. STRIPE_COLUMNS 1; The DATA disk group has 50GB free space. Which two are prerequisites for successful executon of this command? A. COMAPTIBLE.ASM and COMPATIBLE.ADVM must ie set to 11.2 or higher for the DATA disk group. B. The DATA disk group must not ie created with external redundancy. C. The DATA disk group must not contain any other volume. D. The DATA disk group must have at least three failure groups. E. The DATA disk group must have an AU size of 1MB. Aoswern A,D Explanatonn The compatiility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must ie set to 11.2 or higher for the disk group. A high redundancy disk group must contain at least three failure groups. Referencesn Question 4 Which two statements are true aiout v$asm – views in clustered environment? A. They exist ioth in ASM and RDBMS instances, and display the same output. B. Their names can ie seen in dict when connected to an ASM instance. C. Their names can ie seen in v$fxed_taile when connected to an instance of any type that is started. D. They exist in ioth in ASM and RDBSM instances, iut they can display diferent outputs depending on the instance type. E. gv$asm_atriiute can ie used to display the ASM_POWER_LIMIT atriiute of all ASM instances in the cluster. Aoswern B,D Explanatonn You can use the views to oitain informaton aiout Oracle Automatc Storage Management Cluster File System (OracleACFS). These views are accessiile from the Oracle ASM instance.

Default data fle templates are only created iy ASM when a normal redundancy disk group is created. B. Default template setngs for redundancy depends on the disk group redundancy. C. Default templates for a disk group can ie modifed. D. Default template setng for striping depends on disk group redundancy. E. Templates may ie shared across disk groups.

4. Aoswern A,B Explanatonn Default template setngs depend on the diskgroup type. The default template for data fles for a normal redundancy. Referencesn Question 6 Which three statements are true regarding Flex ASM on a four-node cluster consistng of three-hui nodes and a leaf node? A. An ASM instance and dataiase instances can coexist on the same hui node. B. A dataiase instance on a hui node canie a client of an ASM instance running on any leaf node. C. A dataiase instance on a hui node can ie a client of an ASM instance running on any hui node. D. A dataiase instance on a leaf node can ie a client of an ASM instance running on any hui node. E. A dataiase instance on a hui node uses an ASM instance as an I:O server when requestng I:O to diskgroups. F. ASM Cluster File System (ASFS) can only ie deployed on hui nodes. Aoswern A,C,F Explanatonn Architecturally Oracle Flex Cluster comprises of a Hui and Leafarchitecture where in only the Hui nodes will only have direct access to Oracle Cluster Registry (OCR) and Votng Disk (VD). However applicaton can access the dataiase via Leaf nodes without ASM instance NOT running on Leaf nodes. The connecton to the dataiase is through Hui making it transparent for the applicaton. Noten Hui Nodes are connected among them via private network and have direct access to the shared storage just like previous versions. These nodes are the ones that access the Oracle Cluster Registry (OCR) and Votng Disk (VD) directly. Leaf Nodes are lighter and are not connected among them, neither accesses the shared storage like the Hui Nodes. Each Leaf Node communicates with the Hui Node that is atached to, and it is connected to the cluster via the Hui Node that is linked to.

Oracle dataiases from releases older than 12c cannot use Flex ASM. B. ACFS may only ie confgured on a hui node running an ASM instance. C. Instances ofASM-iased dataiases on hosts that have no ASM instance running, require Flex ASM. D. Flex ASM requires that I:Os requests ie sent through an ASM Proxy Instance, regardless of dataiase and ASM instance placement in a cluster.

5. E. Hui nodes with connectonsfrom multple leaf nodes must run an ASM instance. Aoswern B,E Explanatonn Bn Oracle Automatc Storage Management Cluster File System (Oracle ACFS) can only ie run on the hui nodes, not the leaf nodes. Architecturally Oracle Flex Cluster comprises of a Hui and Leaf architecture where in only the Hui nodes will only have direct access to Oracle Cluster Registry (OCR) and Votng Disk (VD). En applicaton can access the dataiase via Leaf nodes without ASM instance NOT running on Leaf nodes. The connecton to the dataiaseis through Hui making it transparent for the applicaton. Question 8 A directory +DATA:ORCL:DATAFILE:USERS exists in ASM. USERS is a user created directory; ORCL and DATAFILE are system generated directories. Which two statements are true aiout user-created directories? A. You can create suidirectories under the USERS directory. B. You cannot rename a user-created suidirectory. C. You cannot drop a directory containing aliases unless you delete the aliases frst. D. You cannot create a user-defned directory at the root (+) level. E. You cannot create a nested suidirectory :USERS:2019 under USERS with a single CREATE DIRETORY command even if directory USER1 doesn’t exist. Aoswern A,C Question 9 Which three components are integral parts of High Availaiility NFS (HANFS)? A. Applicaton VIP B. DHCP C. ExportFS D. HAVIP E. NFS F. HAIP Aoswern C,D,E Explanatonn CDn In additon to ACFS:ADVM and ASM, HANFS also relies on new Oracle 12.1 Clusterware (CRS) resources, namely the HAVIP and the ExportFS. DEn High Availaiility Network File Storage (NFS) for Oracle Grid Infrastructureprovides uninterrupted service of NFS V2:V3:V9 exported paths iy exposing NFS exports on Highly Availaile Virtual IPs(HAVIP) and using Oracle Clusterware agents to ensure that the HAVIPs and NFS exports are always online.
