Scenario: An administrator configured link aggregation on two switch ports that are connected to the XenServer network interface card (NIC) bond. NO network flow is possible on the NIC bond.
How can the administrator resolve this networking issue?
A. Remove the NIC bond.
B. Change the NIC bond to active/active.
C. Configure link aggregation with failover.
D. Remove link aggregation from the switch ports.
E. Ensure that the IP address is correct on the NIC bond.
Scenario: An administrator is able to connect on some ports of a XenServer and NOT connect on others. The XenServer responds by indicating that some of the ports are blocked. The interface in question is the first Ethernet NIC.
Which two commands should the administrator run from the XenServer console to find out if any ports are blocked? (Choose two.)
A. ip addr -r
B. ethtool -Al
C. netreport -r
D. iptables -nL
E. tcpdump -i eth0
Scenario: An administrator of a pool of XenServers has discovered that NOT all XenServers are showing the same time in the event logs. NTP is configured and enabled on all XenServers. The servers are in the same location and use the same NTP server.
From the console of each XenServer, which command should the administrator type to determine if the date and time zone of each server is causing the issue?
A. date
B. time
C. timeutil
D. tzselect
Scenario: An administrator needs to restore a virtual machine from a snapshot. All virtual machines on the XenServer host are stored on a NFS storage repository.
Which two methods can the administrator take to restore the virtual machine? (Choose two.)
A. Use the xe snapshot-revert command.
B. Restore the NFS share from a previous snapshot.
C. Restore the virtual machine using the XenCenter snapshot module.
D. Use the XenServer console's "restore virtual machine metadata" function.
The development team requires that a virtual machine be restored to the state it was on the previous day, but will need parallel access to the current state of the virtual machine.
What can an administrator do to meet the requirements of the scenario?
A. Revert the virtual machine back to the previous snapshot and start it.
B. Create a new virtual machine from the previous snapshot and start it.
C. Make a copy of the virtual machine, revert it to the previous snapshot and start it.
D. Take a snapshot of the current state of the virtual machine and revert it to the previous snapshot.
Scenario: A new email virus threat has been publicly announced, but virus definitions are NOT yet available for protection. An administrator manages the virtual machine hosting the mail server of the company. There are NO redundant mail servers available and mail flow CANNOT be interrupted.
What can the administrator do as a preventive tactic?
A. Preserve the virtual machine by exporting it to an external drive.
B. Enable high availablity to ensure the virtual machine remains online.
C. Make a copy of the virtual machine in case the original gets infected.
D. Perform an online backup by taking a snapshot of the virtual machine.
Scenario: An administrator is in the process of updating a database server on a virtual machine and would like to preserve its current state in case something goes wrong. The virtual machine is being used in a production environment and needs to remain online.
What can the administrator do to meet the requirements of the scenario?
A. Preserve the virtual machine by exporting it to an external drive.
B. Enable high availablity to ensure the virtual machine remains online.
C. Perform an online backup by taking a snapshot of the virtual machine.
D. Make a copy of the virtual machine in case the original needs to be deleted.
Scenario: An administrator of a XenServer pool needs to ensure that virtual machines will be available in the event of a disaster. A backup XenServer implementation is in place in another location; however, there is NO replication available.
In preparation for disaster recovery, which step should the administrator perform?
A. Run the vm-export command.
B. Run the vm-migrate command.
C. Take a snapshot of the virtual machines.
D. Install backup agents on the virtual machines.
Scenario: An administrator is making changes to a stand-alone XenServer host and has taken it offline. The virtual machines on that host will be restored to another host.
The administrator needs to the virtual machines to meet the requirements of the scenario. (Choose the correct option to complete the sentence.)
A. copy
B. export
C. protect
D. migrate
An administrator needs to back up the metadata of a XenServer pool on a scheduled basis to replicate to the Disaster Recovery site.
Which two steps must the administrator take to backup the pool? (Choose two.)
A. Open XenCenter.
B. Open the XenServer console.
C. Configure scheduled snapshots.
D. Select Backup, Restore and Update.
E. Select Resource Pool Configuration.
