Structurally, a network includes a set of nodes interconnected by a set of transmission lines, and each connection is called a ________________.
- A.
Servers
- B.
Client
- C.
Link
- D.
Host
Correct Answer
C. LinkExplanation
In the context of client-server architecture, a server is a computer program running to serve the requests of other programs, the "clients". Thus, the "server" performs some computational task on behalf of "clients". The clients either run on the same computer or connect through the network. In most common use, a server (also called a host) is a physical computer (a hardware system) dedicated to running one or more such services (as a host), to serve the needs of users of the other computers on the network. Depending on the computing service that it offers it could be a database server, file server, mail server, print server, web server, or other.Rate this question:

- B.
HTTP (Hypertext Transfer Protocol)
- C.
LACP (Link Aggregation Control Protocol)
- D.
SMTP (Simple Mail Transfer Protocol)
Correct Answer
C. LACP (Link Aggregation Control Protocol)Explanation
Within the IEEE specification, the Link Aggregation Control Protocol (LACP) provides a method to control the bundling of several physical ports together to form a single logical channel. LACP allows a network device to negotiate an automatic bundling of links by sending LACP packets to the peer (a directly connected device that also implements LACP).Rate this question:

The TCP/IP reference model has 4 layers. Choose the correct layers.
- A.
Host-to-network layer; network or IP (Internet Protocol) layer; transport or TCP (Transmission Control Protocol) layer; application layer
- B.
Host-to-host layer; network or IP (Intranet Protocol) layer; transport or TCP (Transmission Control Protocol) layer; application layer
- C.
Network-to-network layer; network or IP (Internet Protocol) layer; transport or TCP (Transmission Control Protocol) layer; application layer
- D.
Network-to-host layer; FTP (File Transfer Protocol) layer; transport or TCP (Transmission Control Protocol) layer; application layer
Correct Answer
A. Host-to-network layer; network or IP (Internet Protocol) layer; transport or TCP (Transmission Control Protocol) layer; application layerExplanation
The TCP/IP reference model consists of four layers: the host-to-network layer, the network or IP (Internet Protocol) layer, the transport or TCP (Transmission Control Protocol) layer, and the application layer. Each layer has its own specific functions and responsibilities in the communication process. The host-to-network layer is responsible for the physical transmission of data between the host and the network. The network or IP layer handles the routing of data packets across different networks using IP addresses. The transport or TCP layer ensures reliable delivery of data between hosts using TCP. Finally, the application layer provides services and protocols for specific applications to communicate over the network.Rate this question:

The implementation of caching and replication DOES NOT lead to consistency problems. State true or false.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
There is one serious drawback to caching and replication that may adversely affect scalability.
