Answer:
b) Plus sign
Explanation:
The plus sign or addition operator (+) accomplishes concatenation. This is a greatly used in the Java's output Statement to combine values coming from different data types into a formatted output
consider the code snippet below which uses concatenation to output information about an individual
public class Name {
public static void main(String[] args) {
int age =18;
String name = "John";
System.out.println("His name is "+name +" and his age is "+age);
}
}
The + operator has been used to concatenate the int value age and the String value stored in name to the output
The decimal form of the 11001101.00111001.10101001.01000010 binary ip address is 205.57.169.66.
An IP address is a binary number with 32 bits. The 32 bits are divided into four octets, which are groupings of 8 bits each. An IP address, however, is shown as a dotted decimal number (for example: 205.57. 32.9).
Memory regions are given binary addresses by the computer system. But in order to access a memory location, the system utilises a certain number of bits. We can address two memory regions with 1 bit. We can address 4 memory locations with 2 bits and 8 memory locations with 3 bits.
The 4 sets of 8 bits in each of the 4 directions are simply written down to create the 32-bit binary IP address.

The answer is IPS (Intrusion Prevention Systems)
The Intrusion Prevention Systems and Intrusion Detection Systems (IDS) are two security technologies that secure networks and are very similar in how they work. The IDS detects unauthorized user activities, attacks, and network compromises, and also alerts. The IPS, on the other hand, as mentioned, is very similar to the IDS, except that in addition to detecting and alerting, it can also takes action to prevent breaches.
Answer:
b. nslookup Serv2.csmpub.local and then nslookup IPAddress returned from the first nslookup.
Explanation:
That's the best command to use when one wants to verify whether PTR record exists for a Serv2.csmpub.local host
