DENIUS [597]

Answer:

a. gpupdate /force

Explanation:

Based on the information provided within the question it can be said that if the administrator does not want to wait she can use the command gpupdate /force. This command allows the individual to update both the local Group Policy settings and Active Directory-based settings. This the force tag makes it so that the policy is immediately update.

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of

allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

You are a very small company that sells healthcare insurance plans. You estimate that the breach of your customer database will

lozanna [386]

Answer:

C. Accept the risk

Explanation:

The first option is close but might not be suitable for a small company considering it's cost.

The second option which is to spend fifty thousand dollars per year on a data loss prevention solution is projected to cost you more than the risk.

The third option isn't specific and lacks a course of action.

In the output at the command line from a router that reads - ip ospf message-digest-key 1 md5 CISCO-123 - what does the CISCO-12

11111nata11111 [884]

Answer: a) it is used as a password.

Explanation:

In order to be able to exchange routing information , CISCO routers use an authentication process, so when they send a message (a HELLO message for instance) the router that receives the message confirms that the message is authentic.

There are several types of authentication in OSPF, null, plain and MD5.

The difference between them is as follows:

1) null, implies that no password is included in the packet header, it's the default mode.

2) plain: In this type of authentication, the password is sent transparently from a router to his neighbor, as a plain text which makes it vulnerable to attacks from packet inspection software, like Sniffer.

3) MD5, is a more secure mode, in which the password is not sent directly, but a hash built based on the packet contents and the password itself instead.

MD5 (Message Digest 5) is the name of the algoritm used to build the hash that receiver will compare with the sent by the sender in order to confirm authentication.

The chosen password, is placed at the end of the command, after the type of authentication (MD5 in this case), which in this case is "CISCO-123".

Raymond has to send a number of large documents to his charterer accountant for filing his taxes. Which email etiquette should R

CaHeK987 [17]

Raymond should compress the files, and then at the very least ask what would be the appropriate time to email the attachment. It is important to practice good etiquette when using email. If you are sending an email that has attachments, always make sure to mention it in the body of the email. Raymond should also ZIP or compress his large attachments before sending them. This will make them easier to send.
