An operations ticket reports: "Oracle VM Manager jobs time out against Server S3, but not S1 or S2." S3 remains reachable over SSH, its guests are serving requests, and its storage is healthy. What is the most informative next step?
Correct answer: B - Check S3's Agent service and Manager-to-Agent connectivity
A deployment team must reuse a production VM template to create test VMs in a different repository and on an isolated test network. The production template must remain unchanged. The disk destinations and VNIC network mappings need to be specified before copies are created. Choose the appropriate cloning workflow.
Correct answer: D - Use an advanced clone with a clone definition for the target disks and networks
During a failure test, an Oracle VM Server loses power abruptly. Its HA-enabled VM later boots on another member of the clustered pool from the shared repository. The application recovers, but its previous in-memory session is gone. Does this outcome show that live migration failed?
Correct answer: A - No; HA restarted the VM after host failure rather than preserving its running memory state
A supported Windows guest runs in HVM mode on Oracle VM 3.0. Profiling points to overhead in emulated disk and network devices, rather than a shortage of CPU or memory. The operating system must be retained, and supported Oracle VM paravirtualized drivers are available. Which change targets the measured bottleneck?
Correct answer: C - Install paravirtualized I/O drivers in the HVM guest
A DRS network policy monitors an active-passive bond made from two 1 Gbit/s NICs. The configured threshold is 60%. Throughout the relevant monitoring period, transmitted traffic is 720 Mbit/s and received traffic is 180 Mbit/s. How should the policy interpret this load?
Correct answer: B - 72% utilization; transmit traffic alone exceeds the threshold
After moving a VM's VNIC to a newly configured Oracle VM network, its static IP address and gateway still belong to VLAN 120. Packet capture on the host uplink shows that VM's traffic leaving with VLAN tag 130. Other VMs on VLAN 120 reach the same gateway. Identify the correction that restores the intended network path.
Correct answer: D - Map the VNIC to the Oracle VM network associated with VLAN 120
A recovery drill restores Oracle VM Manager's database successfully. However, the storage repository containing the guests' virtual disks was destroyed, and those disks were not backed up. A colleague expects Manager to rebuild their contents from its database. What is the flaw in that expectation?
Correct answer: A - Manager stores management information, not the contents of guest virtual disks
The overnight objective for a clustered server pool is to run the same workloads on fewer physical servers and power off the emptied hosts. Live migration and remote power control have been validated. The current DRS policy is balancing workload but leaving every host powered on. Which policy change matches the objective?
Correct answer: C - Replace DRS with DPM for that server pool
Server S3 has been discovered and added to the same pool as S1 and S2. An existing NFS repository works on S1 and S2 and is visible in Oracle VM Manager, but it is not available for VM deployment on S3. The export permits access from S3, and its network path is working. Which action makes the existing repository available to S3 without changing its contents?
Correct answer: C - Present the existing repository to S3
Two standalone Linux VMs have mounted the same shareable virtual disk read/write. The disk contains an ordinary ext3 filesystem, and neither guest uses cluster-aware storage coordination. Both applications now report filesystem errors. The disk image resides on a healthy OCFS2 repository. What is the immediate priority?
Correct answer: A - Stop writes and eliminate concurrent guest access before attempting offline filesystem repair
