To increase fault-tolerance, the security administrator for Corp has installed an active/passive firewall cluster where the seco

nd firewall is held in reserve in case of primary firewall failure. Stateful firewall inspection is being used in the firewall implementation. There have been numerous reports of dropped connections with external clients. Which of the following is MOST likely the cause of this problem?
(A) All packets are traversing the passive firewall causing the connections to be dropped.
(B) The heartbeat between the firewalls is not enabled.
(C) Inbound packets are traversing the active firewall and return traffic is being sent through the passive firewall.
(D) All packets are traversing the active firewall causing the connections to be dropped.

What is a thermal reservoir?
Mekhanik [1.2K]

Answer:

Explanation:

Thermal reservoir:

   It is the body which have infinite amount of heat capacity and store large amount of heat.The temperature of thermal reservoir is constant and does not change with time.The temperature of thermal reservoir is not change even heat is going out from reservoir or heat going inside the reservoir.The temperature of thermal reservoir remains constant and does not depend on the surroundings.

A three-story school has interior column bays that are spaced 25 ft apart in both directions. If the loading on the flat roof is
Lady_Fox [76]

Answer:

Explanation:

Floor Load:

Lo= 50psf

At= 25x25 = 625 square feet

L= Lo(0.25 +15/\sqrt{KuAt)}

L=50(0.25+15/\sqrt{(4)(625)}= 13.1psf

%reduction= 13.1/50 = 26%

Fr= 3[(13.1psf)(25ft)(25ft)+(20psf)(25ft)(25ft)]= 62k

A motorist is driving his car at 60km/hr when he observes that a traffic light 250m ahead turns red. The traffic light is
Alecsey [184]

Explanation:

Okay soo-

Given-

u = 60 km/hr = 60×1000/3600=50/3 m/s

t = 20 s

s = 250 m

a = ?

v = ?

Solution -

Here, acceleration is uniform.

(a) According to 2nd kinematics equation,

s = ut + ½at^2

250 = 50/3 ×20 + 0.5×a×20×20

250-1000/3=200a

(750-1000)/3=200a

a = -250/(3×200)

a = -5/12

a = 0.4167 m/s^2

The required uniform acceleration of the car is 0.4167 m/s^2.

(b) According to 1st kinematics equation

v = u + at

v = 50/3 + (-5/12)×20

v = 50/3-25/3

v = 25/3

v = 8.33 m/s

The speed of the car as it passes the traffic light is 8.33 m/s.

Good luck!

a television set having apower rating of 120w and electric lawnmower of power rating 1kw are both connected to a 250v supply if
Soloha48 [4]

Answer:

<u>Television </u>

Power = 120 w

p.d = 240 v

I = p / v

I = 120 / 240 = 0.5

Fuse can be used 3A

<u>lawnmower</u>

Power = 1000w

p.d = 240 v

I = 1000/ 240 = 4.16

Fuse can be used = 5A

Steel bar A of 5 mm diameter is subject to a stress of 500 MPa. Aluminum bar B of 10 mm diameter is subject to a stress of 150 M
weqwewe [10]

Answer:

aluminum bar carrying a higher load than steel bar

Explanation:

Given data;

steel abr

diameter = 5 mm

stress = 500 MPa

aluminium bar

diameter = 10 mm

stress = 150 MPa

we know

stress = laod/area

for steel bar

500 = \frac{P}{\frac{\pi}{4} 5^2}

solving for P

P = 9817.47 N

for Aluminium bar

150 = \frac{P}{\frac{\pi}{4} 10^2}

solving for P

P = 11790 N

aluminum bar carrying a higher load than steel bar
