Question 1

How does the use of storage tiering affect the performance of virtual machines?

Accepted Answer

Storage tiering is an example of a data center storage technology that can further increase performance by dividing storage devices into tiers based on access speed. A virtual machine manager can then dynamically move VMs that require a lot of disk I/O to higher speed storage tiers running on fast devices such as SSD drives.

Question 3

What are frames, and how are MAC addresses used to receive a frame on the network?

Accepted Answer

Both physical and virtual network adapters transfer data between network computers in packets of data bits called frames. In addition to data, frames include a Media Access Control (MAC address used to identify the sender and receiver. Network adapters receive frames by "listening" to network transmissions and checking each frame's MAC address. When a network adapter "sees" a frame with its MAC address, it transfers data bits from that frame into memory and then notifies the OS that the frame has been received. The OS then transfers data from the network adapter to an application, based on the information in the frame.

Question 4

How is the iSCSI connection process typically made secure?

Accepted Answer

A)  The Challenge Handshake Authentication Protocol is used to create a secure connection by encrypting the logon using a secret key. 
B)  The Password Authentication Protocol is used to pass authentication data, after which the connection is secured by symmetric encryption. 
C)  The RADIUS authentication protocol is utilized to log in to a RADIUS server that authenticates both parties, after which encryption is enabled. 
D)  The Kerberos protocol is used to facilitate the use of LDAP logins for authentication to the iSCSI target, after which the communication is secured via IPsec.
