After upgrading an ESXi host to vSphere 5.x from vSphere 4.x, which three actions must be taken? (Choose three.)
A.
Update any scripts that reference host SCSI devices.
B.
Configure ESXi host networking
C.
Configure licensing
D.
Reconnect managed hosts to vCenter Server
E.
Configure the ESXi firewall
Explanation:
"If vCenter Server manages the host, you must reconnect the host to vCenter Server by right-clicking the host in the vCenter Server inventory and selecting Connect."

I would have said C, D, E…as some services will be blocked by default after upgrade.
I dont know why SCSI host devices should be a problem.

I agree with you. But cannot find any supporting doc.

The host sdX devices might be renumbered after the upgrade. If necessary, update any scripts that
reference sdX devices. (SCSI)

The host firewall configuration is affected. When you migrate from ESX 4.x to ESXi 5.0, the ESX 4.x rule sets list is replaced by the new rule sets list in ESXi 5.0. However, the migration preserves the status of services (enabled/disabled) and the list of allowed IP addresses that were added by the ESX firewall configuration tool, esxcfg-firewall. Customized firewall rules that were created in ESX 4.x. are not preserved after the upgrade. Custom ports that were opened by using the ESX 4.x esxcfg-firewall command do not remain open after the upgrade to ESXi 5.0.

I agree – The host firewall is affected therefore it must be reconfigured (E)

After you upgrade or migrate a host, take the following actions:
View the upgrade logs. You can use the vSphere Client to export the log files.
If vCenter Server manages the host, you must reconnect the host to vCenter Server by right-clicking the host in the vCenter Server inventory and selecting Connect.
When the upgrade is complete, ESXi is in evaluation mode. The evaluation mode period is 60 days. You must reapply your license or assign an upgraded license to your product within 60 days after the upgrade. Use the License Portal and the vSphere Client to configure licensing. See
On the VMware Web site, log in to your account page to access the license portal. From the license portal, upgrade your ESXi license. Use the vSphere Client to assign the upgraded license key to the host.
The host sdX devices might be renumbered after the upgrade. If necessary, update any scripts that reference sdX devices.
After the upgrade, convert any ESX 3.x-style /adv/Disk/MaskLUNs LUN masks to the claim rule format. Run the esxcli storage core claimrule convert command in the vSphere Command-Line Interface (vCLI). This command converts the /adv/Disk/MaskLUNs advanced configuration entry in /etc/vmware/esx.conf to claim rules with MASK_PATH as the plug-in.

D is correct, if the server was in the vSphere cluster, but it does not say that in the question. Therefore, I voted for A, C, and E as Firewall is definitely different in ESX 4 vs. ESXi 5.
