Virtual Networking
73. What do you know about virtual Networking?
Different VMs connected to a network, which are running on physical servers connected to them logically is called Virtual Networking.
74. What is Virtual Standard Switch?
For the communication of VMs on a single physical host, VSS is used. It works exactly like a physical switch.
75. What is Virtual Distributed Switch?
VDS is responsible for administration and management of a virtual network.
76. How many maximum number of ports are available for a host?
For a switch, there are 4096 ports available for a particular host.
77. What are the main advantages of a VDS?
Following are the advantages of a VDS:
- Monitoring
- Management and provisioning.
- Administration.
78. Why

Limit: Sets limit for CPU cycle.
Reservation: Defines the mode for CPU or memory for the starting up of VM.
82. What is the use of alarms?
Alarms are created using vSphere Web Client. These notify the occurrence of an event.
83. What do we use vRealize Operation (vROP)?
To monitor the virtual environment, vROP is used which enables to use the operations like capacity optimization, monitoring and performance analytics.
84. Which types of deployments can be used in the deployment of vCenter Server?
External and Internal deployments are the two types of deployments used for vCenter Server.
85. How can vCenter servers be secured?
Using Active Directory, specific roles can be assigned to the users of a vCenter Servers. This also helps to use the Virtual Environment in an efficient way.
86. What is the function of Storage vMotion?
The function of Storage vMotion is to move virtual disk of a VM from a datastore to another.
Advanced Questions:

Which two resources are important and need to be considered carefully while designing a vSphere Cloud?
Network and storage resources are important to be planned carefully for designing a v Sphere Cloud.
Can you name 4 operations that take place on VMKernel layer?
Following are the operations that take place on VMKernel Layer:
- IP Storage (NFS or iSCSI)
- Fault Tolerance.
- Virtual
What are the exact features of a distributed database? a) Is always connected to the internet b) Always requires more than three machines c) Users see the data in one global schema. d) Have to require the physical location of the data when an update is done
7.7.1 Data Owners 1. One whose going to access files, one who owns file, who requires his data to be secure. 2. Data owners are responsible for encrypting the data by generating private key. MMCOE, Department of Computer Engineering, 2015-2016 26 Regeneration of code based cloud storage 3.
Having root access on the Huawei Ascend M860 comes with great responsibility. It means that you will have full control over the Ascend smartphone root file system. That same root file system stores your critical system files and if you were to delete any, it could brick your device. As serious as that sounds, you can always backup your device using the internal SD card. Those of you looking to save some more space on the internal memory can connect an external SD card and backup using Titanium backup to that external drive.
Now, it is possible for virtual machines (VMs) to be created, deleted and migrated in a matter of seconds or minutes. That means keeping an up-to-date inventory of VMs is near impossible, with the distinct possibility they may not be backed up at all.
2.1 AWS Networking AWS provide a kind of networking services that also provide private network connections to the cloud, scalable DNS and tools to make logistically solitary networks. There are also have prevalent networking services comprise the Amazon Virtual Private Cloud (VPC) and Amazon Direct Connect. Amazon VPC generates a logically solitary set of Amazon EC2 for example which can be connected to current network using VPN connection. Amazon VPC generates a private cloud inside AWS, while deposition built-in security with security groups and network access control lists. When using Amazon EC2, VPC is free.
In order to access a UNIX system, and use it , you need to connect to the system. You can login: Locally Remotely Login Types In general, there are two ways: Command-line Login GUI Login Connecting Locally Connecting locally means, you are directly logging into the UNIX system. Network connectivity is not required.
Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
Forums: I have used the forums and looked around it a lot. I know how to navigate through the server 's forums and find and help out players on here. Also, the forum is a place where staff and players are able to interact with each other and communicate. It connects the players and knowing how to navigate and being able to help out on the forums is a big part of being a staff member. The forums is also a source of helping out players.
Virtual Private Network enables you to use internet to connect to machines while making sure that the connections are private. VPN is very convenient, but it is not necessary if you want remote clients to connect to you Linux or Unix server. Many people concerned about fast connections might then ask "how fast can a VPN go?" The simplest answer is that; a VPN can go as fast as other types of connection and can be faster if there is fast internet connection at both ends of the network. Actually VPN servers can be as fast as any other internet connections although there are several things that you should do to have faster VPN internet speeds.
Therefore, the database can be any type such as SQL, Not Only SQL (NOSQL), or other. Observation_4: The CSP needs to apply a virtualization technology on storage resources to serve CSUs’ demands efficiently. Therefore, a
There are different kinds of operating systems in the technology world. Microsoft makes Windows which is the most widely used operating system in the world. 90% of the world uses it. The most used after Microsoft is Apple which makes OSX. There is also Ubuntu and Unix.

For that reason, he was trying to sell his stock, but the board of Directors lent him $341 million, along with 2% interest rate.
In a relational database management system the data access is privileged which means that the database administrator has the authority of giving access of data to some particular users which makes the data secure. 3. Easy to use: This type of database uses tables which is better and easy to create and use. Disadvantages of RDBMS: 1. Slow:
