What is Private VLAN and Port Types ?
Private VLANs provide layer 2 isolation between ports within the same broadcast domain.
There are three types of PVLAN ports:
There are three types of PVLAN ports:
- Promiscuous :->A promiscuous port can communicate with all interfaces, including the isolated and community ports within a PVLAN.
- Isolated:-> An isolated port has complete Layer 2 separation from the other ports within the same PVLAN, but not from the promiscuous ports. PVLANs block all traffic to isolated ports except traffic from promiscuous ports. Traffic from isolated port is forwarded only to promiscuous ports.
- Community:-> Community ports communicate among themselves and with their promiscuous ports. These interfaces are separated at Layer 2 from all other interfaces in other communities or isolated ports within their PVLAN.
What is a Difference Between NAT and Proxy Server ?
Proxy Server:->
Proxy server An application-based translation of network access requests.Provision for local user authentication for access to untrusted network. Logging and control of port/protocol access may be possible. Normally used to connect two networks.
NAT :->
Network Address Application-based translation of requests for service or Translation (NAT) connection to an external network. No user authentication is possible, and port/protocol filtering is not usually performed here. Used to redirect requests through one interface. Requests for connection at outside interface must have originated from inside host or they are dropped.

What is DMZ ?
A computer host or small network inserted as a “neutral zone” between a company’s private network and the outside public network. The DMZ prevents outside users from getting direct access to a server that has company data. (The term comes from the geographic buffer zone that was set up between North
Korea and South Korea following the United Nations “police action” in the early 1950s.) A DMZ is an optional and more secure approach to a firewall and effectively acts as a proxy Server.

New Features and Improvements in VMware Workstation 10.0.1
New
Features and Improvements in VMware Workstation 10.0.1
VMware Workstation 10 delivers best-in-class Windows 8
support, and innovative
new features that transform the way technical professionals
work with virtual
machines, whether they reside on their PCs or on private
enterprise clouds.
*New Operating System
Support
Support has been
added for:
-Windows 8.1
-Windows 8.1 Enterprise
-Windows Server 2012 R2
-Ubuntu 13.10
As well as for the latest Fedora, CentOS, Red Hat and
OpenSUSE releases.
*VMware Hardware
Version 10
This version of VMware Workstation includes VMware hardware
Version 10 and is
compatible with vSphere 5.5. Hardware versions introduce new
virtual hardware
functionality and new features while enabling VMware to run
legacy operating
systems in our virtual machines. New features included in
this hardware
version:
*16 vCPUs
Virtual machines can now run with up to 16 virtual CPUs.
This enables very
processor intensive applications to be run in a virtual
machine.
Note: Running virtual machines with 16 vCPUs requires that
both your host
and guest operating system support 16 logical processors.
Your physical
machine must have at least 8 cores with hyper-threading
enabled to power
on a virtual machine with this configuration.
