Strategies to help you tackle Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration
Oracle Restart is correct because it is the component specifically designed for standalone (non-clustered) servers to provide automatic restart capabilities for Oracle databases, listeners, and ASM instances. Cluster Ready Services (CRS) and Oracle Clusterware are components used in clustered RAC environments, not standalone configurations. Grid Naming Service (GNS) is used for Dynamic Host Configuration Protocol (DHCP) and dynamic DNS resolution in cluster environments, not for restart management.
3 IP addresses is correct because Oracle recommends configuring three IP addresses for SCAN to provide optimal load balancing and high availability. The SCAN name resolves to three IP addresses in DNS (or GNS), and each address is assigned to a SCAN listener on different nodes in the cluster. While SCAN can technically work with 1 or 2 addresses, 3 is the recommended best practice for production environments. Having only 1 or 2 addresses reduces availability and load balancing capabilities.
3 failure groups is correct because HIGH redundancy in ASM requires a minimum of 3 failure groups to maintain three-way mirroring. HIGH redundancy maintains three copies of each extent, with each copy placed in a different failure group. This configuration can tolerate the loss of two failure groups while maintaining data availability. EXTERNAL redundancy requires 1 failure group, and NORMAL redundancy requires 2 failure groups, but HIGH redundancy specifically needs at least 3 failure groups.
GV$SESSION is correct because this global view shows session information across all instances in the cluster, including the MACHINE column which identifies which node the connection came through. By analyzing the distribution of sessions across instances, you can identify load balancing issues. While V$LISTENER and GV$LISTENER_ENDPOINT provide listener configuration information, they don't show active connection distribution. V$LISTENER_NETWORK is not a standard Oracle view. GV$SESSION provides the comprehensive session-level data needed to analyze connection distribution patterns.
Private interconnect network is correct because it is absolutely mandatory for RAC cluster operations. The private interconnect is used for Cache Fusion (transferring data blocks between instances), cluster heartbeat communications, and cluster synchronization services. Without a properly configured private interconnect, the cluster cannot function. The public network is used for client connections but isn't sufficient alone. ASM network is an optional separate network for ASM traffic in newer versions. SCAN is a naming convention that uses the public network, not a separate network type.
