• Question 313:

  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?

  A. Restart the RAID resynchronization process

  B. Perform a P2V migration of the server

  C. Swap the failed hard drive with a fresh one

  D. Restore the server from backup

  Correct Answer: D

  RAID 5 is a disk array configuration that uses parity to provide fault tolerance and data recovery. RAID 5 can tolerate the failure of one disk, but not two or more disks. If a second disk fails during the resynchronization process, the data on the RAID 5 array will be lost and unrecoverable. The only way to make the server fully operational is to restore the data from a backup source.

• Question 314:

  A systems administrator is informed that a database server containing PHI and PII is unencrypted. The environment does not support VM encryption, nor does it have a key management system. The server needs to be able to be rebooted for patching without manual intervention.

  Which of the following will BEST resolve this issue?

  A. Ensure all database queries are encrypted

  B. Create an IPSec tunnel between the database server and its clients

  C. Enable protocol encryption between the storage and the hypervisor

  D. Enable volume encryption on the storage

  E. Enable OS encryption

  Correct Answer: D

  Volume encryption is a type of encryption that protects data at the storage level by encrypting an entire disk or partition. Volume encryption can provide strong security for data at rest, as it prevents unauthorized access to the data even if the storage device is lost, stolen, or compromised. Volume encryption can also support automatic booting without manual intervention, as it can use a pre-boot authentication mechanism that does not require user input. Enabling volume encryption on the storage is the best way to resolve the issue of having an unencrypted database server containing PHI and PII, as it can protect the sensitive data without relying on VM encryption or a key management system.

Users are now reporting that when they browse to the website, they receive a message indicating the service is unavailable. The cloud administrator logs into the server, runs a netstat command, and notices the following relevant output:

  

  Which of the following actions should the cloud administrator take to resolve the issue?

  A. Assign a new IP address of 192.168.100.10 to the web server

  B. Modify the firewall on 72.135.10.100 to allow only UDP

  C. Configure the WAF to filter requests from 17.3.130.3

  D. Update the gateway on the web server to use 72.135.10.1

  Correct Answer: D

  Updating the gateway on the web server to use 72.135.10.1 is the best action to take to resolve the issue of the web server being unavailable after being deployed in a public IaaS provider and assigned the public IP address of 72.135.10.100. Updating the gateway can ensure that the web server can communicate with the Internet and other networks by using the correct router or device that connects the web server's network to other networks. Updating the gateway can also improve performance and reliability, as it can avoid any routing errors or conflicts that may prevent the web server from responding to remote login requests.

• Question 316:

  A systems administrator is troubleshooting performance issues with a Windows VDI environment. Users have reported that VDI performance is very slow at the start of the work day, but the performance is fine during the rest of the day.

  Which of the following is the MOST likely cause of the issue?

  A. Disk I/O limits

  B. Affinity rule

  C. CPU oversubscription

  D. RAM usage

  Correct Answer: C

• Question 317:

  A cloud administrator is switching hosting companies and using the same script that was previously used to deploy VMs in the new cloud. The script is returning errors that the command was not found.

  Which of the following is the MOST likely cause of the script failure?

  A. Account mismatches

  B. IP address changes

  C. API version incompatibility

  D. Server name changes

  Correct Answer: C

  An application programming interface (API) is a set of rules or protocols that defines how different systems or applications can communicate or interact with each other. An API version is a specific iteration or release of an API that may have different features or functionalities than previous or subsequent versions. API version incompatibility is the most likely cause of the script failure when switching hosting companies and using the same script that was previously used to deploy VMs in the new cloud, as it can result in errors or failures when trying to execute commands or functions that are not supported or recognized by the new cloud provider's API version. The issue can be resolved by updating or modifying the script to match the new cloud provider's API version. References: CompTIA Cloud+ Certification Exam Objectives, page 13, section 2.5
