A computer network that uses logical media to create connections between virtual machines is a[n] ______. a. private network b public network c. physical network d. virtual network |
d. virtual network |
|
|
|
A VLAN is a ______ LAN created on a physical network switch. |
Logical |
|
|
|
True or False? The two types of VPNs are remote-access and point-to-point. |
False |
Remote access and site-to-site |
|
|
A[n] ______ protocol protects a private communication stream between two endpoints. |
Tunneling |
In computer networks, a tunneling protocol allows a network user to access or provide a network service that the underlying network does not support or provide directly. |
|
|
True of False? Digital signatures identify the originator of a transmitted message. |
True |
A digital signature (not to be confused with a digital certificate) is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document. |
|
|
A virtual HBA incorporates what feature that permits each virtual server to have a unique WWN? a. IPsec b. NPIV c. SAN d. VMK |
b. NPIV |
N_Port ID virtualization (NPIV) is a technology that defines how multiple virtual servers can share a single physical Fibre Channel port identification (ID). |
|
|
The encryption protocol that applies two encryption methods, tunnel or transport, is _____. a. PPTP b. L2TP c. IPsec d. SSL |
c. IPsec |
Tunnel mode protects the internal routing information by encrypting the IP header of the original packet. The original packet is encapsulated by a another set of IP headers. The transport mode encrypts only the payload and ESP trailer; so the IP header of the original packet is not encrypted. |
|
|
A______ encryption protocol encodes only the payload in a data packet. |
transport |
|
|
|
True or False? A vswitch is a physical device. |
False |
VSwitch is short for Virtual Switch and represents networking entities connecting Virtual Machines in a virtual network at layer 2. |
|
|
What virtual network device is seen by the host operating system as a physical device installed on the host server? a. vrouter b. vswitch c. vNIC d. pNIC |
c. vNIC |
VNIC is a virtualized Network Interface Card, used by a Virtual Machine as its network interface. A VNIC is assigned a MAC address. Each MAC address corresponds with a single virtual NIC, which is used by a virtual machine. |
|
|
True or False? One of the ways a vNIC connects to a VM is a VMKernel connection. |
True |
The VMkernel is the kernel used by VMware ESX. It provides basic operating system services needed to support virtualization |
|
|
A[n]______ hypervisor is installed "bare metal." |
Type I |
|
|
|
A[n]______ virtual network interconnects VMs and the VMM. |
virtual device based |
Virtual Machine Manager (VMM) Virtual Machine (VM) |
|
|
True or False? A Type I hypervisor is installed on top of a server's operating system. |
False |
|
|
|
Which virtual network device allows physical and virtual machines to communicate within a virtual network? a. vrouter b. vNIC c. vswitch d. vbridge |
c. vswitch |
