Hi,
Can anyone tell me if I have picked the correct TRUE statements ..
From the pairs of terms given below, choose the option that offers, in the correct order, the most appropriate pair for the blanks in the following statement.
_______DHCP_ is a protocol that enables network devices to share a pool of IP addresses. This protocol operates at the __________Application__ layer of the OSI model.
A
DNS network
B
DNS session
C
DHCP network
D
DHCP application
E
SMTP application
F
SMTP session
I believe the correct answer to be D
Select two true answers from
A
The ISM band is the name given to a band of radio frequencies running
from exactly 2.4 MHz to exactly 2.4835 MHz. No - GHz
B
Channels 6, 8 and 10 are non-overlapping 802.11g Wi-Fi channels. No
C
A wireless node with a single transmit/receive antenna is unable to use the CSMA/CD protocol.
D
Wireless network management overheads are increased when nodes operate at the fringes of the wireless range.
E
Channel bonding, frame aggregation and block acknowledgement are
methods used toincreasenetwork efficiency in 802.11g networks.
F
SISO stands for Standard Interrupt Signal Order. I guess not :-0(
I feel that D and E are true !
Can you please comment
Thank you :-)
To determine if the statement from the pairs of terms is correct, we need to evaluate the options.
For the first blank, the correct term is "DHCP," which stands for Dynamic Host Configuration Protocol. DHCP is indeed a protocol that enables network devices to share a pool of IP addresses. So, you have picked the correct option for the first blank.
For the second blank, the correct term is "Application layer" of the OSI model. The Application layer is responsible for providing network services to user applications. Among the given options, "DHCP application" is the correct choice, as DHCP operates at the Application layer. Therefore, you have picked the correct option for the second blank.
Regarding the second part of your question about selecting the true statements from options A to F, let's evaluate them one by one:
A - The ISM band is the name given to a band of radio frequencies running from exactly 2.4 MHz to exactly 2.4835 MHz. This statement is incorrect because the frequencies in the ISM band range from 2.4 GHz to 2.4835 GHz, not MHz.
B - Channels 6, 8, and 10 are non-overlapping 802.11g Wi-Fi channels. This statement is incorrect because channels 6 and 10 overlap. Only channels 1, 6, and 11 are non-overlapping in the 2.4 GHz band.
C - A wireless node with a single transmit/receive antenna is unable to use the CSMA/CD protocol. This statement is true. CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is used in wired Ethernet networks, not wireless networks.
D - Wireless network management overheads are increased when nodes operate at the fringes of the wireless range. This statement is true. When nodes operate at the fringes of the wireless range, the signal quality decreases, leading to increased management overhead for maintaining the connection.
E - Channel bonding, frame aggregation, and block acknowledgement are methods used to increase network efficiency in 802.11g networks. This statement is true. Channel bonding, frame aggregation, and block acknowledgment are techniques used in 802.11g to increase the speed and efficiency of wireless networks.
F - SISO stands for Standard Interrupt Signal Order. This statement is false. SISO stands for Single Input Single Output and refers to wireless systems with one antenna for transmitting and receiving.
Based on the evaluation, the correct true statements are C and D. So, your selection of D and E as true statements is incorrect. The correct options are C and D.
I hope this explanation helps!
