Answer:

True.

Explanation:

If a firm puts servers that are internet facing directly on the internet then the servers are exposed to external attacks and these attacks can be from anywhere in the world.

The server becomes vulnerable or unsafe and attackers can attack and can manipulate or tamper the server code from anywhere in the world.

A switch that is configured to use the Spanning Tree Protocol will place a port in ____________ mode if sending traffic to it ma
Rashid [163]

Answer:

Blocking Mode    

Explanation:

Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called loops.

When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.

This affects the performance of the network as the result of broadcast packets flooding.

STP puts one port of the switch to forwarding mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to blocking mode and the one port that is left after this is placed in forward mode.

Spanning Tree Algorithm is used by STP to determine the optimal path  of switch to the network.

Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.

This information helps STP to eliminate the redundant paths.

So this is how STP allows only one active path to the destination while blocking all other paths to avoid switching loop.

Who would be a tippee for purposes of insider trading? a. a janitor who gathers information by reading files on corporate counse
vesna_86 [32]

Answer:

Option A is correct.

Explanation:

A janitor that collects data through reviewing reports on a business counsel's desk could be a tippee for insider trading activities.

Probably, the justification for insider trading remains wrong being that it offers each insider the undue benefit on and around the marketplace, gets the insider's preferences beyond them for which they assume the trustee responsibility, as well as enables the insider to unfairly manipulate the cost of the inventory of a business.

So, the following are the reason the other options are not correct according to the given scenario.

A router receives a packet and determines the outbound link for the packet. When the packet arrives, 2/3 of one other packet is
vlada-n [284]

Answer:

Queuing Delay is 0.08 seconds

Explanation:

The answer follows a formula that is relatively easy to use and is detailed below.

Queuing Delay = [(L - x) + (nL)] / R

where,

L is packet length given as 3,000 bytes

x is the currently transmitted packet given as 2/3 * 3,000 = 2,000

n is the number of packets waiting in the Que given as 5

R is the rate of transmission given as 4 Mbps (4 * 10^6 Bps)

We can simply plug in the above information in the equation for computing Queuing Delay.

Lets take the numerator first which would be [(3000 - 2000) + (5 * 3000)]

The numerator would be 16000 bytes. These are being transmitted at 4Mbps. So, 16000*4*5 = 320,000 "bits"

Queuing Delay= 320,000/4000000

Queuing Delay = 0.08 seconds.

As we can see, the formula is quite intuitive to use. You are simply taking the number of packets to be transmitting, incorporating the partially transmitted packet, multiplying by the number of packets and the rate of transmission and then dividing the product by the rate of transmission to compute what the delay in the Que is.
