Consider the following two code segments, which are both intended to determine the longest of the three strings "pea", "pear", and "pearl" that occur in String str. For example, if str has the value "the pear in the bowl", the code segments should both print "pear" and if str has the value "the pea and the pearl", the code segments should both print "pearl". Assume that str contains at least one instance of "pea".I.

if (str.indexOf("pea") >= 0)

{

System.out.println("pea");

}

else if (str.indexOf("pear") >= 0)

{

System.out.println("pear");

}

else if (str.indexOf("pearl") >= 0)

{

System.out.println("pearl");

}

II.

if (str.indexOf("pearl") >= 0)

{

System.out.println("pearl");

}

else if (str.indexOf("pear") >= 0)

{

System.out.println("pear");

}

else if (str.indexOf("pea") >= 0)

{

System.out.println("pea");

}

Which of the following best describes the output produced by code segment I and code segment II?

Both code segment I and code segment II produce correct output for all values of str.

Neither code segment I nor code segment II produce correct output for all values of str.

Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pear" but not "pearl".

Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pearl".

Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".

Answers

Answer 1
Answer:

Answer:

Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".

Explanation:

The main issue with the first code segment is the way how the if else if condition are arranged. The "pea" is checked at the earliest time in the first code segment and therefore so long as there is the "pea" exist in the string (regardless there is pear or pearl exist in the string as well), the if condition will become true and display "pea" to terminal. This is the reason why the code segment 1 only work for the values of str that contain "pea".

Which of the following statements is NOT true regarding the Security Configuration and Analysis (SCA) tool?a. It evaluates the current security state of computers in accordance with Microsoft security recommendations.
b. It allows an administrator to analyze a computer and compare its configuration settings with a baseline.
c. It can apply a baseline to force current computer settings to match the settings defined in the baseline.
d. It uses security templates to store the settings that make up baselines.

Answers

Answer: a. It evaluates the current security state of computers in accordance with Microsoft security recommendations

Explanation:

The Security Configuration and Analysis tool allows the configuration of local computers through the application of the settings in a security template to the local policy.

This allows an administrator to analyze a computer and compare its configuration settings with a baseline. The Security Configuration and Analysis (SCA) tool also uses security templates to store the settings that make up baselines.

Therefore, based on the options given, the correct option is A as the SCA tool doesn't evaluate the current security state of computers in accordance with Microsoft security recommendations.

At what layer in the TCP/IP protocol hierarchy could a firewall be placed to filter incoming traffic by means of:a) message content
b) source address
c) type of application​​

Answers

The most significant protocol at layer 3, often known as the network layer, is the Internet Protocol, or IP.The IP protocol, the industry standard for packet routing among interconnected networks, is the source of the Internet's name.  Thus, option C is correct.

What are the TCP/IP protocol hierarchy could a firewall?

Application-layer firewalls operate at the TCP/IP stack's application level (all browser traffic, or all telnet or ftp traffic, for example), and thus have the ability to intercept any packets going to or from an application. They stop different packets (usually dropping them without acknowledgment to the sender).

Firewalls are frequently positioned at a network's edge. An external interface is the one that is located outside the network, while an internal interface is the one that is located inside the firewall.

Therefore, The terms “unprotected” and “protected,” respectively, are sometimes used to describe these two interfaces.

What are computer languages?

The computer languages are Java and Python is in their conversion; the Java compiler converts Java source code into an intermediate code known as bytecode, whereas the Python interpreter converts Python source code into machine code line by line.

Curly braces are used in Java to define the beginning and end of each function and class definition, whereas indentation is used in Python to separate code into separate blocks.

Multiple inheritances is done partially through interfaces in Java, whereas Python continues to support both solitary and multiple inheritances.

Therefore, the correct option is b. Python.
