Anetwork engineer is attempting to design-in resiliency characteristics for an enterprise network’s vpn services.
if the engineer wants to ensure some resilience against zero-day vulnerabilities exploited
against the vpn implementation, which of the following decisions would best support this
objective?
a. implement a reverse proxy for vpn traffic that is defended and monitored by the organization’s soc with near-real-time alerting to administrators.
b. subscribe to a managed service provider capable of supporting the mitigation of advanced ddos attacks on the enterprise’s pool of vpn concentrators.
c. distribute the vpn concentrators across multiple systems at different physical sites to ensure some backup services are available in the event of primary site loss.
d. employ a second vpn layer concurrently where the other layer’s cryptographic implementation is sourced from a different vendor.

Felicia wants to become a head surgeon by december 2013. she designs the career milestones that she would need to complete her goal. by june 2013, she was not licensed. which best describes what she should do?

1. the program must provide following functions to extract some statistics. note that the data_list parameter specified in these functions may be the same for all functions or different for different functions—that is your choice. a skeleton file is provided on mirmir. a) open_file()prompts the user to enter a year number for the data file. the program will check whether the year is between 1990 and 2015 (both inclusive). if year number is valid, the program will try to open data file with file name ‘year.txt’, where is the year. appropriate error message should be shown if the data file cannot be opened or if the year number is invalid. this function will loop until it receives proper input and successfully opens the file. it returns a file pointer and year. i. hint: use string concatenation to construct the file name b) read_file(fp)has one parameter, a file pointer read. this function returns a list of your choosing containing data you need for other parts of this project. c) find_average(data_list) takes a list of data (of some organization of your choosing) and returns the average salary. the function does not print anything. hints: i. this is not the average of the last column of data. it is not mathematically valid to find an average by finding the average of averages—for example, in this case there are many more in the lowest category than in the highest category. ii. how many wage earners are considered in finding the average (denominator)

What is a point-in-time measurement of system performance?
