Answer:
A). Fault tolerance
Explanation:
The Microsoft Azure is described as the cloud computing service that is known for its flexibility, cost-effectiveness, and quick and easy compliance to fulfill the company's requirements.
As per the question, in order to ensure that 'some servers are available in case of a single Azure data center going offline for an increased time period', the recommendation must include the 'fault tolerance' ability of Azure services. Azure infrastructure has the ability to immediately react in case of a failure to restore the servers and its services. In case of hardware failure, crashing of hard-disks, or short-term availability problems with servers, Azure predicts and manages such failures effectively. Thus, <u>option A</u> is the correct answer.
Answer:
<u>The total time elapsed from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B is </u><u>25.11 ms</u>
Explanation:
Host A first converts the analog signal to a digital 64kbps stream and then groups it into 56-byte packets. The time taken for this can be calculated as:
time taken 1= 
= (56 x 8) bits / 64 x 10³ bits/s
= 7 x 10⁻³s
time taken 1= 7 ms
The transmission rate of the packet from Host A to Host B is 4 Mbps. The time taken to transfer the packets can be calculated as:
time taken 2= (56 x 8) bits / 4 x 10⁶ bits/s
= 1.12 x 10⁻⁴ s
time taken 2= 112 μs
The propagation delay is 18 ms.
To calculate the total time elapsed, we need to add up all the time taken at each individual stage.
<u />
<u> = Time taken 1 + Time taken 2 + Propagation Delay</u>
= 7 ms + 112 μs + 18 ms
= 0.025112 s
= 25.11 ms
Answer:
Putty
Explanation:
PuTTY is an SSH and telnet client for Windows and Unix platform. PuTTY is an open source terminal emulator, serial console and network file transfer application. It does not only support SSH and telnet, it also supports other network protocols like SCP, rlogin, and raw socket connection.
To make use of the SSH client on windows, you need to first download and then install the PuTTY software.
