Many college students and recent grads destroy their resumes by accompanying them with halfhearted or downright terrible cover letters. While some employers don't bother reading cover letters, most do. And they will quickly eliminate you if you make these cover letter mistakes
How it advances our lives and helps us in so many ways
Answer:
A small company is requesting a quote to refresh its wireless network. The company currently runs 60 autonomous APs and has plans to increase wireless density by 50% in the near future. The requirements state that the chosen solution should significantly decrease the management overhead of the current wireless network. The following should be recommended by the vendor in response to the quote request:
B. The use of autonomous APs with a wireless controller.
Explanation:
- The option A and D are not correct as the use of lightweight APs are not required here because they are already using autonomous APs which are fulfilling their needs.
- The option B is correct as the use of autonomous APs with a wireless controller will allow them to decrease the management overhead as the wireless controller is used to manage the Access points in larger quantities.
- The option C is incorrect as the load balancers are used to increase the capacity and reliability of applications as they distribute the traffic over number of servers so it is unable to decrease the management overhead.
Answer:
Test B.
Explanation:
Test A - 95% effective with 10% false positive rate.
Test B -90% effective with 5% false positive rate.
Test A and B are independent methods.
One of the tests is carried out on a person and turns out to be positive.
To calculate the effectiveness of the test,
Test A = Effectiveness in percentage divided by the false positive rate.
95/10 = 9.5
Test B = Effectiveness in percentage divided by the false positive rate.
90/5 = 18.
Test B has a higher effective rate than Test A.
Therefore Test B is more indicative of a positive result than Test A.
Answer:
1. Changing the IP address
2. Selecting Ethernet Ports
3. Rename the Pointers
4. Renaming the Second Disk Drive
5. Hostnames must be unique
6. Rename the VM name
Explanation:
When we clone the VM, we have to make sure that Cloned VM should have unique system information and network addresses in and out of guest OS.
If UUID’s of all cloned VM's are different then DHCP will get separate ip addresses for those. Suppose if the IP addresses are static or If the IP address was hardcoded then it has to be changed to new IP address manually. If this is not done then it will cause duplicate IP’s and will cause networking issues.
When Cloned VM is created then the ethernet port has to be chosen correctly to make sure that LAN networking is correct.
You should specify the disk capacity. If you choose disk capacity as single file then it will create one vmdk file. So, specify the correct disk capacity, If you did not choose the disk file as single file then you may end up having multiple .vmdk files. So in that case you need to rename the pointers of copy of vmdk files.
Rename the Second Disk Drive. For example : You may find two VM files with VM Copy.vmdk, So you have to rename second disk to VM Copy-1.vmdk or any other name.
The cloned VM copies the parent virtual machine and it also includes the VM name. To avoid problems caused by having VM's with duplicate names on the network, give the VM in the cloned VM a unique name.
You have to make sure that hostnames are different as well. Hostname resolution will lead to conflict if its same on both VM's.
