True or False? When assessing the performance of an existing system, the metrics developed should reflect resource demands during key processing periods of the organization. |
True |
|
|
|
A(n) ______ consists of virtual devices. |
virtual network |
A virtual network is a computer network that consists, at least in part, of virtual network links. A virtual network link is a link that does not consist of a physical (wired or wireless) connection between two computing devices but is implemented using methods of network virtualization.
|
|
|
What network-level address is assigned to a vNIC? a. WWN b. MAC c. IP d. pNIC |
b. MAC |
Media access control address (MAC address)
|
|
|
True or False? A clone and a snapshot are essentially the same thing. |
False |
A clone is a new VM that is a copy of the original. A snapshot is a backup of a point in time for that VM, the snapshot allows you to restore to a point in time to the same VM.
|
|
|
______ are software devices that provide logical connections for vNICs to the virtual network. |
Vswitches or virtual switches |
|
|
|
A trunk line carries traffic from more than one virtual network element. What is added to frames to identify the source VLAN of the frame? a. VM tagging b. VLAN tagging c. vswitch d. IDWWN |
b. VLAN tagging |
VLAN, otherwise known as Virtual LAN, is a type of local area network innovation that enables administrators to break up physical connectivity from logical network connectivity. |
|
|
True or False? A process VM is limited to only the resources defined in its configuration. |
True |
|
|
|
A(n) ______ is a preconfigured baseline that contains a standard model configuration with which you can create new VMs. |
VM template |
|
|
|
What is the file format associated with vdisks? a. NTFS b. NFS c. VHS d. VHD |
d. VHD |
VHD (Virtual Hard Disk) |
|
|
True or False? Virtualizing a physical disk breaks it into extents, which can span two or more physical disk drives. |
True |
|
|
|
Which vdisk file format method uses a parent image for original data content and a child image for any changes made to the data? a. Differencing hard disk b. Dynamic hard disk c. Fixed hard disk d. Linked hard disk |
a. Differencing hard disk |
|
|
|
A(n) ______ is a logical partition created within a physical storage area network. |
vdisk or virtual disk |
A logical partition, commonly called an LPAR, is a subset of a computer's hardware resources, virtualized as a separate computer. In effect, a physical machine can be partitioned into multiple logical partitions, each hosting a separate operating system. |
|
|
True or False? A VSAN is a collection of specific ports on SAN switches. |
True |
virtual storage area network (VSAN) |
|
|
The purpose of______ an SAN is to limit access to data resources to only selected authorized users |
zoning |
Zoning is a fabric-based service in a storage area network (SAN) that groups together hosts and storage nodes that require communication. The essential requirement for performing zoning is that the nodes can communicate only if they are members of the same zone. Nodes can also be members of multiple zones, permitting flexibility while using the method.

|
What type of data backup captures only the data that has changed since the last full backup? a. Differential b. Incremental c. Reverse delta d. Periodic |
a. Differential |
