Answer:
- limitation and control of network ports, protocols and services.
- Continuous vulnerability assessment and remediation.
Explanation:
The TCP or transmission control protocol is a layer 4 protocol (transport), that reliably transports packets in sequential segments to an application in the destination computer, using the ip address and the port number of the application.
The ICMP sent during the TCP/ip activities, can render the network vulnerable to attacks. limitation and control of the network ports, protocols and services and continuous assessment would mitigate the vulnerability of the TCP/ip model.
Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.
Answer:
Step 1 : Create an Indicator Variable for metro cities using formula mentioned in formula bar.
Step 2: Filter the Data on Metro cities i.e. select only those cities with Metro Indicator 1.
Step 3: Paste this filtered data to a new sheet.
Step 4: Go to Data - Data Analysis - Regression
Step 5: Enter the range of Y-variable and X-variable as shown. Select Output range and click on residuals. It will give you Output Summary and the Predicted Values along with Residuals
