A systems administrator swapped a failed hard drive on a server with a RAID 5 array. During the RAID resynchronization, a second hard drive failed. Which of the following actions will make the server fully operational?
Answer(s): D
D. Restore the server from backup.With two hard drives failed on a RAID 5 array, the server will not be fully operational until the data is restored from a backup. RAID 5 arrays are designed to tolerate a single drive failure, but if a second drive fails during the resynchronization process, the array will be unable to rebuild and the data will be lost.
A cloud administrator recently deployed an update to the network drivers of several servers. Following the update, one of the servers no longer responds to remote login requests. The cloud administrator investigates the issue and gathers the following information:-The cloud management console shows the VM is running and the CPU and memory utilization is at or near 0%.-The cloud management console does not show an IP address for that server.-A DNS lookup shows the hostname resolves to an IP address.-The server is a member of the same security group as the others.-The cloud administrator is able to log in remotely to the other servers without issue.Which of the following is the MOST likely cause of the server being unavailable?
Answer(s): A
A. The network driver updates did not apply successfully, and the interface is in a down state.Based on the given information, the most likely cause of the server being unavailable is that the network driver updates did not apply successfully, and the interface is in a down state. The fact that the cloud management console does not show an IP address for the server suggests that the network interface is not functioning correctly. The fact that a DNS lookup shows the hostname resolving to an IP address indicates that DNS is working correctly, but the server is not responding to network requests.
A company is planning to migrate applications to a public cloud, and the Chief Information Officer (CIO) would like to know the cost per business unit for the applications in the cloud. Before the migration, which of the following should the administrator implement FIRST to assist with reporting the cost for each business unit?
Answer(s): B
B. TaggingImplementing tagging would be the first step to assist with reporting the cost for each business unit. Tagging resources with labels that indicate which business unit or project they belong to will enable the cloud administrator to easily separate the cost of the resources used by each unit or project.An SLA (Service Level Agreement) report would not be useful for reporting the cost for each business unit, as SLA reports focus on availability and performance metrics.Quotas are used to set limits on the amount of resources that can be consumed by a particular user or group, but they would not provide information about the cost of the resources used.Showback is a reporting mechanism that provides visibility into the cost of cloud resources used by each business unit or department, but it requires accurate cost data, which can only be obtained through the implementation of tagging or another cost allocation mechanism.
