Answer:

d.) black-box testing

Explanation:

Software testing can be regarded as procedures/process engage in the verification of a system, it helps in detection of failure in the software, then after knowing the defect , then it can be corrected. Black Box Testing can be regarded as a type of software testing method whereby internal structure as well as design of the item under test is not known by one testing it. In this testing internal structure of code/ program is unknown when testing the software, it is very useful in checking functionality of a particular application. Some of the black box testing techniques commonly used are; Equivalence Partitioning, Cause effect graphing as well as Boundary value analysis. It should be noted that the purpose of black-box testing is to isolate the behavior of a given component of software.

Two routers, R1 and R2, connect using an Ethernet over MPLS service The service provides point-to-point service between these tw
liberstina [14]

Answer: b) R1 will connect to a physical Ethernet link, with the other end of the cable connected to a device at the WAN service provider point of presence.

.d) R1 will forward data link frames to R2 using an Ethernet header/trailer.

Explanation:

Here we have to understand what is MLPS. MLPS is a protocol which identifies the shortest route for the transfer of messages between routers instead of the longest route.

Here we are given a WAN which is a wide area network. Using layer 2 Ethernet service the frames are transmitted across the routers within the WAN.

Option A is incorrect as as connecting the other end of the cable to the R2 would reduce the functionality of the WAN.  Option C is incorrect as HDLC header trailer has no effect.

Option B and D are correct as Ethernet header/ trailer has the same size every frame and to maintain the functionality of the WAN one end must be connected to point of presence(PoP).

lions [1.4K]

Answer:

0.119

Explanation:

50 independent fair games

Mean will be 50/2 = 25

Standard deviation of the loosing probability is :

\sqrt{50*0.5*0.5} * 10 = 33.536

we have to loose 33 times out of 50 games.

To find the approximate probability we use z- value table.

z value =  \frac{33-25}{3.35}

z - value = 2.2659

Looking at the z-value table we get 0.119.

4.22 lab*: program: automobile service invoice(1) output a menu of automotive services and the corresponding cost of each servic
azamat

To write the code for this exercise, we must be familiar with Python's computational language.

The attachment contains the code.

As a result, the Python code can be written as follows:

0 service1 cost

0 service2 cost

print("Services at Davey's Auto Shop")

print("Oil change: $35; Tire rotation: $19; Car wash: $7; Car wax: $12;"

input = service1 ("Select first service: ")

product2 = input ("Select second service: ")

If "Oil change" is service 1, then

35 service1 cost

Tire rotation: elif service1 == true

cost1 service1 = 19

"Car wash," if service1 is true:

cost service1 = 7

"Car wax" if service1 is true:

cost service1 = 12

if (service1) == "-":

service 1 equals "No service"

0 service1 cost

When service2 equals "Oil change,"

35 service2 cost

Tire rotation: elif service2 == true

cost2 service2 = 19

"Car wash" if service2 is true:

cost2 service2 = 7

"Car wax" if service2 is true:

cost2 service2 = 12
