The DNS server at your headquarters holds a standard primary zone for the abc domain. A branch office connected by a slow WAN li

nk holds a secondary zone for abc. Updates to the zone aren't frequent. How can you decrease the amount of WAN traffic caused by the secondary zone checking for zone updates?

Lasso: R example

To run Lasso Regression you can re-use the glmnet() function, but with the alpha parameter set to 1.

# Perform 10-fold cross-validation to select lambda --------------------------- lambdas_to_try <- 10^seq(-3, 5, length.out = 100) # Setting alpha = 1 implements lasso regression lasso_cv <- cv.glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = TRUE, nfolds = 10) # Plot cross-validation results plot(lasso_cv)

Best cross-validated lambda lambda_cv <- lasso_cv$lambda.min # Fit final model, get its sum of squared residuals and multiple R-squared model_cv <- glmnet(X, y, alpha = 1, lambda = lambda_cv, standardize = TRUE) y_hat_cv <- predict(model_cv, X) ssr_cv <- t(y - y_hat_cv) %*% (y - y_hat_cv) rsq_lasso_cv <- cor(y, y_hat_cv)^2 # See how increasing lambda shrinks the coefficients -------------------------- # Each line shows coefficients for one variables, for different lambdas. # The higher the lambda, the more the coefficients are shrinked towards zero. res <- glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = FALSE) plot(res, xvar = "lambda") legend("bottomright", lwd = 1, col = 1:6, legend = colnames(X), cex = .7)

What are some reasons DNS is necessary? Check all that apply. A. It maps local addresses to simple names without editing hosts f
dsp73
Domain Name Servers (DNS) are certainly necessary for easy access of resources across a network. The applicable options of the above are A and B - below are explanations as to why.

A: Computers generally are set to automatically obtain DNS information from the network they are connected to or can be pointed to a specific DNS server. This allows for records of where resources (network attach storage devices, other computers on local network, or even website server details) are located on a “master” kind of list so that the local machine’s host file does not have to be routinely updated to contain new addresses.

B: DNS, as explained partially by the answer to A, maintains a type-able or “human readable” domain name for the actual server’s IP address so we don’t have to memorize or keep a list of IPs for where we want to visit on the web (although, Google’s 8.8.8.8 IP address does make it easy). It shows an association between a name/domain name and an IP address so that we can enter something simple (Google.com) and the computer knows where to go (the server at IP address 8.8.8.8) so it can show you the content you want to see.

C: DNS would only simplify remote access if your were attempting LAN (Local Area Network) remote access of another computer on your network. DNS would not make it easier for remote access of a computer on the internet, as most DNS used in non-commercial settings are created and maintained by third-parties that will not put a specific record for one of your computers in it - not that you would want them to either, since it could lead to an open cyber attack.

D: Network throughput is a fancy phrase for network speed. It could be possible that different DNS servers could process requests faster than others, but it is not likely to increase network speed on the whole as navigating via IP or DNS records will be relatively the same speed.

Please identify three examples of how the United States is heteronormative
juin [17]

Answer:

Well, let's say you're out at a bar. A friend of yours sees a cute guy, but she's hesitant to make the first move because she assumes the guy would be turned off by that - because we're socialized to believe that women shouldn't approach men like that, lest they come off as desperate. That's heteronormativity.

When she finally gets the courage to go up and talk to him, he begins to call her infantilizing pet names (like honey, baby, and sweetheart) - which would be fine if they'd agreed upon it, but he's just assuming she's cool with it! That's heteronormativity.

When she begins to get uncomfortable by these names, she gets up and leaves. But the guy says something like, "Oh, come on! Women are so sensitive. What's your problem?" That's heteronormativity.

What sorts of routine, seemingly unimportant information would help you learn about or break into another company’s network?
tatuchka [14]

Answer and Explanation:

  • Reboot your Computer from which you need to break into.
  • With your remote Ethernet card embedded and the unprotected passageway will mate up in a flash. You likewise need to change the Service Set Identifier (SSID) on your Ethernet card to coordinate SSID on the system's passage. You can decide to physically constrain your DHCP settings to reestablish, however on the off chance that that gives you any trouble.we need to re-boot it.
  • The Third Man ran a sniffer program that caught the majority of the LAN traffic within this organization. It was transmitted through the remote passageway straight into the Third Man's PC. Passwords. Agreements. Email.
