NEW QUESTION 34
Which of the following is a device that provides local communication between the datalogger and a computer?
- A. Short haul modem
- B. Controllerless modem
- C. Optical modem
- D. Acoustic modem
Answer: A
Explanation:
A short haul modem is a device that provides local communication between the datalogger and a computer
with an RS-232 serial port. It transmits data up to 6.5 miles over a four-wire unconditioned line (two twisted
pairs).
Answer option B is incorrect. An optical modem is a device that is used for converting a computer's electronic
signals into optical signals for transmission over optical fiber. It also converts optical signals from an optical
fiber cable back into electronic signals. It provides higher data transmission rates because it uses extremely
high capacity of the optical fiber cable for transmitting data.
Answer option C is incorrect. An acoustic modem provides wireless communication under water. The optimum
performance of a wireless acoustic modem system depends upon the speed of sound, water depth, existence
of thermocline zones, ambient noise, and seasonal change.
Answer option A is incorrect. A controllerless modem is a hardware-based modem that does not have the
physical communications port controller circuitry. It is also known as WinModem or software modem. A
controllerless modem is very inexpensive and can easily be upgraded with new software.

NEW QUESTION 39
Which of the following is a standard protocol for interfacing external application software with an information
server, commonly a Web server?
- A. IP
- B. DHCP
- C. CGI
- D. TCP
Answer: C
Explanation:
The Common Gateway Interface (CGI) is a standard protocol for interfacing external application software with
an information server, commonly a Web server. The task of such an information server is to respond to
requests (in the case of web servers, requests from client web browsers) by returning output. When a user
requests the name of an entry, the server will retrieve the source of that entry's page (if one exists), transform it
into HTML, and send the result.
Answer option A is incorrect. DHCP is a Dynamic Host Configuration Protocol that allocates unique (IP)
addresses dynamically so that they can be used when no longer needed. A DHCP server is set up in a DHCP
environment with the appropriate configuration parameters for the given network. The key parameters include
the range or "pool" of available IP addresses, correct subnet masks, gateway, and name server addresses.
Answer option B is incorrect. The Internet Protocol (IP) is a protocol used for communicating data across a
packet-switched inter-network using the Internet Protocol Suite, also referred to as TCP/IP.IP is the primary
protocol in the Internet Layer of the Internet Protocol Suite and has the task of delivering distinguished protocol
datagrams (packets) from the source host to the destination host solely based on their addresses. For this
purpose, the Internet Protocol defines addressing methods and structures for datagram encapsulation. The
first major version of addressing structure, now referred to as Internet Protocol Version 4 (IPv4), is still the
dominant protocol of the Internet, although the successor, Internet Protocol Version 6 (IPv6), is being deployed
actively worldwide.
Answer option D is incorrect. Transmission Control Protocol (TCP) is a reliable, connection-oriented protocol
operating at the transport layer of the OSI model. It provides a reliable packet delivery service encapsulated
within the Internet Protocol (IP). TCP guarantees the delivery of packets, ensures proper sequencing of data,
and provides a checksum feature that validates both the packet header and its data for accuracy. If the
network corrupts or loses a TCP packet during transmission, TCP is responsible for retransmitting the faulty
packet. It can transmit large amounts of data. Application layer protocols, such as HTTP and FTP, utilize the
services of TCP to transfer files between clients and servers.
NEW QUESTION 40
Which of the following policies is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly?
- A. Password policy
- B. Remote access policy
- C. Group policy
- D. Information protection policy
Answer: A
Explanation:
A password policy is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly. Password policies are account policies that are related to the users' accounts. Such policies are password-related settings that provide different constraints for the password's usage. Password policies can be configured to enforce users to provide passwords only in a specific way when they try to log on to their computers. These policies increase the effectiveness of the user's computers. Answer option C is incorrect. A group policy specifies how programs, network resources, and the operating system work for users and computers in an organization.
Answer option A is incorrect. An information protection policy ensures that information is appropriately protected from modification or disclosure.
Answer option B is incorrect. Remote access policy is a document that outlines and defines acceptable methods of remotely connecting to the internal network.
