An existing vSphere 4 environment will be upgraded to vSphere 5.x. The current implementation utilizes ESXi 4.1 and the new implementation will use ESXi 5.x.
In which two ways will the new ESXi 5.x implementation differ from the ESXi 4.1 implementation? (Choose two.)
A.
VMware ESXi 5.x provides a host-based firewall.
B.
VMware ESXi 5.x can boot from additional local sources such as a USB drive.
C.
VMware ESXi 5.x can be managed from a web browser.
D.
VMware ESXi 5.x can support virtual machines with larger hard drive configurations.
Are A, C and D not correct for this?
Can someone explain?
all I can say is B, the ESXi 4.1 could boot from a usb.
ESXi 4 does not have a firewall,ESX 4 does.Besides ESXi 5 does have a firewall, but it is not host-based firewall, it’s more for the virtualization layer, the virtual
machines, and the virtual networking layer

B can’t be correct, I have IBM issue thumbdrives with ESXi 4.1 installed on them.
B & D are the correct answer (more or less)
(A) is out as host-based firewall exists (security profile) on both ESXi 4.x and 5.x
(C) the level of web-management done on ESXi 4.x is more or less the same on ESXi 5.x
(B) VMWare is trying to emphasize on the certification (Blue Print) the idea that USB/SD drive-based installation if (fully) supported on ESXi 5.x meaning that you can perform either Fresh or Upgrade installation manually or via scripted-method. ESXi 4.x fresh installation did work on USB, but scripted installation was not supported on USB.
I don’t understand how D can be correct…

Both ESXi 4.1 and 5.0 support VMDKs up to 2 TB – 512 bytes?
Yes, but you can use physical RDM in Vshpere 5 to map hard drives up to 64TB. So D is ok.
However, I think A is better answer than B. There is firewall in ESX 4 (based on IP tables), but there was no firewall in ESXi 4.1. It’s a new feature in version 5.

•ESXi 5.x has a new firewall engine that is not based on iptables
ESXi 4.x VMware ESXi does not support web access at this time. ESXi 5.x The vSphere Web Client provides a browser-based alternative to the traditional vSphere Client, enabling you to connect by browser to an ESXi host directly or indirectly through a vCenter Server
How about C and D?
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2005377
Answer A is correct:
per this KB: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003634
ESXi 4.0/ESXi 4.1 does not include a firewall because it runs a limited set of well-known services and prevents the addition of further services. With such restrictions, the factors that necessitate a firewall are significantly reduced. As such, no firewall is integrated in to ESXi.
D should be right as well per this KB:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2005099
ESXi can boot from a disk larger than 2TB if the system firmware and the firmware on any add-in card that you are using support it. For more information, see the vendor documentation.
The key word in this question is “implementation”. A boot source and a storage layout is implementation related. I agree with B and D after picking the question apart.
C,D
Web client
Rdm physical mode can be 64 TB in 5.1, and only 2 TB on esx4.x
Agreed.
A – wrong because it says HOST-BASED firewall
B – wrong because you can have USB booting on ESXi 4.1 (see http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1020655)
C – you have the web client, which you didn’t before.
D – see http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=3371739
quote “Note: As of ESXi 5.0, support for LUNs larger then 2TB is available with both VMFS5 datastores and Physical-mode RDMs. However, virtual disks used in virtual machines and Virtual-mode RDMs are still limited to 2TB – 512 bytes. For more information, see vSphere 5 FAQ: VMFS-5 (2003813).”

Ref: Whats new in VMware vSphere ESXi 5
“Host UEFI boot support.vSphere 5.0 supports booting ESXi hosts from the Unified Extensible Firmware Interface (UEFI). With UEFI you can boot systems from hard drives, CD-ROM drives, or USB media. Booting over the network requires the legacy BIOS firmware and is not available with UEFI.”

Explanation:
Option A is incorrect, ESXi have a internal firewall.
Page 36 from Vsphere Security – ESXi 5.0.pdf
ESXi Firewall Configuration
ESXi includes a firewall between the management interface and the network. The firewall is enabled by default.
Option B is correct.
Page 28 from vsphere-esxi-vcenter-server-50-installation-setup-guide.pdf
* USB devices. Supported for installing ESXi 5.0. For a list of supported USB devices, see the VMware Compatibility Guide at http://www.vmware.com/resources/compatibility
Option C is incorrect, ESXi have local command-line but is necessary enable it.

Option D is correct. See all Maximum configuration for ESX 4 and ESX5 document.
Some example:

Max CPU – 8
ESX 5
Max CPU – 32
DIFFER is the key here!
A. Is not changed
B. Is not changed
C. Is a difference between 4.1x and 5.x
