When you first purchase a notebook, make sure you have a RECOVERY CD. It enables the restoration of the notebook computer.

A recovery disc is a disc that enables to restore the computer to the same condition when it was bought.

Moreover, a recovery drive refers to a separate partition in the notebook that must contain the required files to restore the device if the system becomes unstable.

A recovery disc can be considered as a drive used to keep a backup of the files (e.g., images) and other types of restoration data.

which two statements about incoming and outgoing interfaces in firewall policies are true? (choose two.)
Ratling [72]

The statements that are true regarding incoming and outgoing interfaces in firewall policies are:

  • A zone can be chosen as the outgoing interface.
  • -Multiple interfaces can be selected as incoming and outgoing interfaces.

<h3>What is a firewall?</h3>

A firewall is a network security device used in computing that monitors and regulates incoming and outgoing network traffic in accordance with pre-established security rules. Typically, a firewall creates a wall between a trustworthy network and an unreliable network, like the Internet.

A firewall aids in defending your network from intruders. A firewall protects your network by operating as a continuous filter that constantly scans incoming data and blocks anything that appears to be suspicious.

Therefore, the statements that are true regarding incoming and outgoing interfaces in firewall policies are:

A zone can be chosen as the outgoing interface.

-Multiple interfaces can be selected as incoming and outgoing interfaces.

4. In this problem, we consider sending real-time voice from Host A to Host B over a packet-switchednetwork (VoIP). Host A conve
mina [271]

Answer:

The time elapsed is 0.017224 s

Solution:

As per the question:

Analog signal to digital bit stream conversion by Host A =64 kbps

Byte packets obtained by Host A = 56 bytes

Rate of transmission = 2 Mbps

Propagation delay = 10 ms = 0.01 s

Now,

Considering the packets' first bit, as its transmission is only after the generation of all the bits in the packet.

Time taken to generate and convert all the bits into digital signal is given by;

t = \frac{Total\ No.\ of\ packets}{A/D\ bit\ stream\ conversion}

t = \frac{56\times 8}{64\times 10^{3}}          (Since, 1 byte = 8 bits)

t = 7 ms = 0.007 s

Time Required for transmission of the packet, t':

t' = \frac{Total\ No.\ of\ packets}{Transmission\ rate}

t' = \frac{56\times 8}{2\times 10^{6}} = 2.24\times 10^{- 4} s

Now, the time elapse between the bit creation and its decoding is given by:

t + t'  + propagation delay= 0.007 + 2.24\times 10^{- 4} s + 0.01= 0.017224 s
