NEW QUESTION # 54
You are updating your Exadata X9M-2 Elastic Database Machine with 6 database servers and 12 High Capacity Storage Servers. You will be using patchmgr to apply updates across the entire machine while still maintaining database availability.
Assuming you are driving patchmgr from an external server, which statement is true about the execution phase?

A. patchmgr cannot apply updates in a rolling manner, you must manually apply patches with the dbnodeudpate and cellupdate tools if high availability is required.
B. patchmgr must be invoked with the -rolling argument. Each component type must be upgraded independently of the other.
C. patchmgr must be invoked with the -rolling argument with all database and storage servers listed in a single input file.
D. patchmgr will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption.

Answer: B

NEW QUESTION # 55
You are planning the monitoring configuration for your Exadata X9M Database Machine.
Which three components are monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins?

A. Oracle clusterware on the database server
B. the Power Distribution Units (PDUs)
C. the storage server ILOM
D. the RDMA over Converged Ethernet (RoCE) switches
E. ASM instances
F. Hybrid Columnar Compression (HCC) ratios on Extended (XT) storage servers

Answer: A,E,F

Explanation:
Exadata-specific Enterprise Manager Plug-Ins are used to monitor different components of the Exadata Database Machine.
1. ASM instances: The Automatic Storage Management (ASM) instances can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the storage space, disk usage, and performance of the ASM instances.
2. Hybrid Columnar Compression (HCC) ratios on Extended (XT) storage servers: The HCC ratios on Extended (XT) storage servers can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the compression ratios and performance of the storage servers.
3. Oracle clusterware on the database server: The Oracle clusterware on the database server can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the health and performance of the clusterware.

NEW QUESTION # 56
An Exadata storage server physical disk on an X9M-2 high-capacity full rack entered the predictive failure state. Which two steps must you perform to replace this failed physical disk?

A. Identify the griddisks located on the failed physical disk and drop them from the associated ASM diskgroups.
B. Add the griddisks back into the ASM diskgroup they used to be a member of.
C. Create a new celldisk and new griddisks on the replaced physical disk.
D. Verify that the griddisks located on the physical disk have been successfully dropped from the associated ASM diskgroups.
E. Replace the failed physical disk.
F. Rebalance the data on the effected griddisks before performing a manual drop command.

Answer: A,E

Explanation:
Once the physical disk has been replaced, you will need to create a new celldisk and griddisks on the replaced physical disk. After the griddisks have been dropped from the associated ASM diskgroups, you can then add the griddisks back into the ASM diskgroup they used to be a member of and rebalance the data on the effected griddisks. Finally, you should verify that the griddisks located on the physical disk have been successfully dropped from the associated ASM diskgroups.
