What happen when we connect Two PC with IP from Same subnets

Scenario 2nd : What happen when we connect Two PC with IP from Same subnets. PC1 -192.168.10.1/24 PC2 - 192.168.10.2 on a two different L2 Switch on different vlans which are connected via a LAN cable.
All ports are access ports
Interview Question : No More Info.
Pc1<SwA>------<SwB>PC2
Q.1 Will they communicate If yes what will be packet/frame flow.
Q.2 If not where will be the packet/frame drop. ? Why.
I need step by step if possible plz how the packet moves , vlan taggings n all internal works that happens behind .. plz
thnx in advnce ....

Hi Abhishesk,
The PCs should communicate each othet.
Since there is no trunk port involved, there is not tagging involved.
Since both the PCs are into the same subnet. PC1 will not need default gateway for the communication with PC2. So PC1 will start with sending ARP request for PC2 MAC address.
Since all the ports in SW1 are in same VLAN, the ARP should reach all ports including the switchport where SW2 is connected to.
Sw2 has got a complete different access port on ALL the switchports. Sw2 will receive the ARP from Sw1. Remember that there is no tagging for the frame. Hence Sw2 will again send the ARP packet to all the ports which belong to same VLAN wherein the packet is received. ie, Sw2 will send the ARP packet to all the ports in Sw2. PC2 will also get the the ARP.
The ARP reply will make it way back using the same logic.
Now both the PCs can start the actual packet exchange.

What happens when an iPod is synchronized with an iTunes library that is bigger than the available space on the iPod?

What happens when an iPod is synchronized with an iTunes library that is bigger than the available space on the iPod? I did this some time ago. On screen was shown available space somewhat less than 120 GB, but maybe somewhere between 10 and 20 GB more in the library. I had to get the iPod updated anyway, so I did proceed. However, afterwards the total content of the library was only about 110 GB. Now I wonder what did actually happen. Was the first sign only corrected for double copies of the same files or lost files or where files deleted from iTunes? And if files where deleted from iTunes, were they also deleted from my computer?

Same as you would if you bought a pc; copy everything from your old computer to your new one. Then you can just sync everything from the new computer, as you did with the old one.

What happens when i connect to itunes when ive used icloud since i first got my device?

Ive always used icloud but now i have ran out of storage i want to back up my devices using itunes, what will happen when i connect my device to itunes for ythe first time? I am using Windows 8.1 and have 3 apple devices (Ipod touch 5, ipad 2, an a ipad mini original)
Thanks in advance!

Yes - if you try to sync, then it will tell you that it is a new device and everything will be erased. When you sync, you are syncing with the data in the actual iTunes Library. You select which Apps, Music, Movies, TV, Photos, Books, etc. that you want to sync to your device in the Device Profile tabs that will display in iTunes when you hook up your device. Whatever you have selected will sync to your device.
If you have your Contacts, Notes, Calendars, etc. already checked to sync with iCloud (not backup, but the items that are tuned on under Settings>iCloud on both your device and your computer), then those will not get replaced.
If everything on your device is purchased from the iTunes Store, you can download it all to your computer by going to the appropriate tab in the iTunes Store, click on Purchased under the Quick Links section to the right, and then download anything that has a cloud next to it.
Here is a support article on syncing:

Time Machine backup created on Mac with a large hard disk. What happens when restore to MacBook Air with small SSD drive?

What if a Time Machine backup was created on a Mac with a large hard disk, e.g. 500GB iMac - and I buy a new MacBook Air with a small SSD hard disk e.g 128GB. What happens when I need to use the larger Time Machine file to set up the new MacBook Air? What happens to all those files that can't fit on the smaller SSD drive?

It is not the HD size, but rather the size of the data it contains. If you right-click your 500GB drive and select "Get Info" you can see how much is actually being used.
Naturally if you are using more space than the new drive has, then you have to make some choices about what you want to keep and what you want to keep archived.
I don't know what options are available but you may simply have to do a manual restore of files you want, in groups.

What happens when Ap has two different gain antennas

Hi all..
I have two question?
In a Warehouse, I have a high density of Access Point 1240, each AP have only the radio b/g active and each AP has two antennas. One antenna is 2.2 dBi and the other antenna is 5.2 dBi. This affect to the signal, or throughput?
The Ap is at around 82 feet high, is out of estandar. What happens if I reduce the transmit power?.Can the wifi client connect to the ap and work fine?
Thanks for your help

#Two differrent gain or antenna type(with or without RF overlap) works good for one client, when more than one client communicating to different antenna would yield poor performance. see the link below.
#dtpc and datarate would also drastically change based on the client connected antenna that is not discussed in the link.
#With one antenna there won't be diversity and yes there will be a performance hit when compared to having multiple antennas.
#Either use two similar model or one antenna, If you don't have two similar antenna model you can still connect one antenna and on AP's antenna diversity setting you can have either left or rigtht based on the antenna connected to the radio port on AP.

What happens when Sync "connects to" local server?

While setting up an account, one of the options is "Connect to." There is a drop-down with a default setting of "Firefox Sync Server." I believe the other option is something about setting up your info on a local server, but I can't find anything in the instructions about it.
I have a Western Digital network attached storage drive which looks just like extra drives to all my PCs. Can Firefox Sync save my data on a device attached to my LAN? If so, can I move the target for the existing account or do I have to make a new account?

HT1751 So what happens when the external hard drive with all of my iTunes media on it crashes??

I moved my iTunes media/library (as well as iPhoto) to an external hard drive many moons ago. It's been a great decision up until today, when the portable hard drive I was using decided to commit suicide. Is it possible to restore the lost media and library files from Time Machine, or are all of my music (and picture) files officially gone??? Help!!

If you have been doing the basics and backing up your computer, then they are not gone. They are in your backup.
Use your backup to put them back.

If I have two laptops connected to a single wireless hard drive, what happens when one laptop wants to go on a trip and the other one needs to stay home?

if I have two laptops connected to a single wireless hard drive (i.e. Time Capsule), what happens when one laptop wants to go on a trip and the other one needs to stay home? I'm afraid I know the answer, but I'm hoping Apple has a great solution to my problem.

What if this little piggy goes to market but this little piggy stays home?
The computer on a trip will do snapshot backups on the hard drive that will then be incorporated into the Time Machine backup once you get it back home. See
OS X Lion- About Time Machine's "local snapshots" on portable Macs
Open the Terminal in the Utilities folder and enter or paste the appropriate command line. Press RETURN and enter your admin password when prompted. It will not be echoed.
To turn them ON: sudo tmutil enablelocal
To turn them OFF: sudo tmutil disablelocal
Note that turning them OFF will also delete all existing snapshots.

When we do a failover to a Replica, what happened to the connected clients? Assuming that the Replica is located in a remote DR site with a different IP configuration.

When we do a failover to a Replica, what happened to the connected clients? Assuming that the Replica is located in a remote DR site with a different IP configuration.
Hi,
I need some guidance here, please.
I have some questions about replication:
When we do a failover to a Replica, what happened to the connected clients? Assuming that the Replica is located in a remote DR site with a different IP configuration.
Is possible to automate the failover process? Just like happens in a cluster.
What changes do I need to do in order to guarantee that my clients reach my replica? For example, I need to do a failover to my Exchange Server Replica and I need to minimize the downtime. The same applies for a DC or a SharePoint Server
  Thanks in advanced.

Hi efebo,
“The same applies for a DC ”
As for replicating virtualized DC (Personally,  I do not suggest to replicate DC , even though it can be replicate ), please refer to following link:
http://technet.microsoft.com/en-us/library/dn250021.aspx
"In short, Exchange does
not support the Hyper-V Replica feature. Exchange has a long history of supporting virtualisation from
Exchange 2003 onwards. It is fully supported to install Exchange
2007,
2010 or
2013 as a virtual machine on Hyper-V, but using the Hyper-V replica feature is not supported.
For details please refer to following link:
http://blogs.technet.com/b/rmilne/archive/2013/07/29/exchange-and-hyper-v-replica-support.aspx
I assuming that the "Remote DR site" and the primary site both have public IPs .
Based on my knowledge you can not access replica site VM  directly after a disaster , maybe you need to rebuild primary site and replicate VM back .

When I connect my iPad with usb to my mac the iPad gives me a "blinking" message asking to trust the computer. Problem is it does not give me enough time to select yes. What am I doing wrong? Help!

When I connect my iPad with usb to my mac the iPad gives me a "blinking" message asking to trust the computer. Problem is it does not give me enough time to select yes. What am I doing wrong? Help!

Everything that you sync to the iPad is done through iTunes or from downloading from the cloud if they are iTunes purchases or through iTunes Match, if subscribed.
It is also not possible to transfer music or certain other files though Bluetooth between other iPhones or Android devices. You can transfer between iOS devices, pictures through devices that are Airdrop capable.

Lost my iPod, remotely locked it through iCloud. What happens when the battery goes out?

Hello!
I lost my Ipod, but managed to locate and lock it remotely through Find my iPod and iCloud. It was located once, but hasn't been located again in the last four days. I think the battery may have run out. What happens when the battery is charged and the iPod turned back on? Does the lock and everything else that can be controlled with Find my iPod still apply?
Thank you!

Yes, because when you remotely lock the iPod via Find my iPod, the lock code is set as the lock code that you would use to unlock the iPod if you used a passcode normally. As long as the iPod is still connected to your Apple ID, Find my iPod should work as log as the iPod is connected to wifi.

When we connect two bw systems to one R/3 system?

Hi ,
When we connect two bw systems to one R/3 system,
could you please exlain what is the imact to SAP and BW in terms of query performance, batch performance,Develoment ,Quality system,security,BW Support.
Thanks in advance.
Regards,
kranthi

you can connect multiple BW to single R3 source system.
In the delta queue (RSA7 in source system), you have a field with the target system, so you don´t have problem if you have many target bw system, because the data selection is done by system field.
Challenge arises when you have multiple R3 feeding to single BW system and then you have to consolidate the master data say 0material fed from different source system R3 then you can consolidate data using consolidated infoobject.
The following components concatenate to the key of a consolidated InfoObject:
1)source system ID (two-character source system ID; permitted values are stored NW BI table RSSOURSYSTEM)
2)one blank character
3)backend object type (four-character backend object type; permitted values are stored BI table RSBWBEOTYP)
4)master data key value as stored in the source system
Note that the key of a consolidated InfoObject solely consists of non-integrated informations from the different source systems. Integration across source systems results from a (maybee repeatedly applied) data consolidation and cleasing process which unveils duplicate master data keys.
Hope it Helps

Hi,what happens when CTAS fails?
Will the table be created with as much data as it fetched before the error occurred.

Just try it and you will see:

Okay...so what do I do? After this it goes to "stopping services", but says it is unable to do that. Then when I open I-tunes it says that the part of the program where the computer connects to the ipod was not installed correctly. this is soooo frustrating. my brother's had an ipod shuffle for about 2 years so itunes was already installed. i was just trying to update it so my ipod video could be read.

Sorry no but here is some info anyway,
We increased MaxPermSize from 192 to 512
We also increased min and max JVM Heap size to 768 and 2048 respectively.
Since then I think we have not experienced this problem more than once.
We also have one server with the default parameters and it seems to work fine.
I believe that size, and number of simultaneous request/responses have an impact on this.
We will now install the latest updates and after that decide whether to start logging jvm activities or not.
Best regards
