What is the process of wrapping high layer data with lower layer data called?
- A.
Re-Wrapping
- B.
Passing
- C.
Encapsulation
- D.
Vectorization
Correct Answer
C. EncapsulationExplanation
Encapsulation is the process of wrapping high layer data with lower layer data. It is a technique used in object-oriented programming to hide the internal details of an object and provide a controlled interface to access and manipulate the data. By encapsulating data, we can ensure data integrity and prevent direct access to the internal state of an object. This helps in maintaining code modularity, reusability, and security.Rate this question:

What is another term used for one-way network communication capability?
- A.
Duplex
- B.
Half-Duplex
- C.
Simplex
- D.
Full-Duplex
Correct Answer
C. SimplexExplanation
Simplex is another term used for one-way network communication capability. In simplex communication, data flows in only one direction, from the sender to the receiver. This means that the receiver can only receive data and cannot send any response back to the sender. It is commonly used in scenarios where only one party needs to transmit information, such as in broadcasting or monitoring systems. Unlike duplex communication, which allows for two-way communication, simplex communication is unidirectional.Rate this question:

What is the host ID given the CIDR IP Address 192.168.205.15/24?
- A.
0.15
- B.
192.168.205.15
- C.
.205.15
- D.
168.205.15
Correct Answer
A. 0.15Explanation
The host ID given the CIDR IP Address 192.168.205.15/24 is 0.15. In CIDR notation, the "/24" indicates that the first 24 bits of the IP address are the network portion, leaving the last 8 bits for the host portion. Therefore, the host ID is the last octet of the IP address, which is 0.15.Rate this question:

What TCP/IP protocol relies on Echo Reply packets to test connectivity between hosts?
- A.
FTP
- B.
IGRP
- C.
ICMP
- D.
TCP
Correct Answer
C. ICMPExplanation
ICMP (Internet Control Message Protocol) relies on Echo Reply packets to test connectivity between hosts. ICMP is responsible for reporting errors and providing diagnostic information in IP networks. Echo Reply packets are used in a process called "ping" to verify if a host is reachable and measure the round-trip time for packets to travel between hosts. ICMP is not a transport layer protocol like TCP, but rather a network layer protocol that operates within the TCP/IP suite. FTP (File Transfer Protocol) and IGRP (Interior Gateway Routing Protocol) are unrelated to testing connectivity using Echo Reply packets.Rate this question:

What TCP/IP protocol is used to inform routers of available multicast groups?
- A.
OSPF
- B.
EIGRP
- C.
IGMP
- D.
IGRP
Correct Answer
C. IGMPExplanation
IGMP (Internet Group Management Protocol) is the correct answer because it is the TCP/IP protocol used to inform routers of available multicast groups. IGMP allows hosts to join or leave multicast groups and informs routers which hosts are interested in receiving multicast traffic. OSPF (Open Shortest Path First), EIGRP (Enhanced Interior Gateway Routing Protocol), and IGRP (Interior Gateway Routing Protocol) are all routing protocols used for different purposes and do not specifically deal with multicast group information.Rate this question:
