Answer:
print("What year of high school are you in?")
grade = input()
grade = grade.lower()
if grade == "freshman":
print("You are in grade: 9")
elif grade == "sophomore":
print("You are in grade: 10")
elif grade == "junior":
print("You are in grade: 11")
elif grade == "senior":
print("You are in grade: 12")
else:
print("Not in high school")
Explanation:
The first line prints the question. "grade = input()" stores the answer the user will type in the terminal into the variable 'grade'.
grade.lower():
The third line lowercases the entire string ("FreshMan" would turn to "freshman"). Python is case-sensitive.
Then, test the string to see if it matches freshman, sophomore, junior, or senior. If the input string matches print the statement inside the if block. The last statement is the else. It prints if nothing else matches.
A host has an address of 100.55.177.99/16. what is the broadcast address for the subnet?
The broadcast address for the 24 subnet is 31 since 192.168.19.24 is the 24 subnet and 32 is the following subnet. Only 192.168.19.26 is the right response.
An IP address is split in half using a subnet mask. The host (computer) is identified by one part, and the network to which it belongs is identified by the other. Examine an IP address and its structure to have a better understanding of how IP addresses and subnet masks operate. The "host address" field of an IP address is typically set to 1, which is the default for routers and the majority of contemporary computer systems, to create broadcast addresses. In some outdated systems, the broadcast address is created by setting the host portion to 0 and they may not be able to use the "1" form.

Which of the following functions are performed by the OSI Transport layer?
a. Control media access, logical topology, and device identification
b. Data segmentation and reassembly
c. End-to-end flow control Format packets for delivery through the media
d. Reliable message delivery Consistent data formatting between dissimilar systems
e. Path identification and selection
Option B is correct. Data segmentation and reassembly. The Transport Layer offers dependable data transmission services to the upper layers by facilitating transparent data flow between end users.
Through flow control, segmentation and de segmentation, and error management, the transport layer manages the dependability of a specific link. Segmenting and reassembling user data is the transport layer's primary duty. In order to account for packet loss or duplication during transmission through the network layer, the transport layer keeps track of these segments if asked. Error correction and data segmentation and de segmentation before and after data is carried across the network are functions performed by the transport layer. Additionally, this layer is in charge of flow control and ensuring that segmented data is delivered over the network in the proper order.

Which of the following is true about half-duplex mode?
a. It requires switches with dedicated switch ports.
b. The device can send and receive at the same time.
c. Collision detection is turned on.
d. Collision detection is turned off.
option c is true It is activated to detect collisions. Only one way at a time can be sent or received by the gadget. This communication must be used by all hub-connected devices.
When a collision is detected in a collision-detection system, the transmitting devices will suspend communications for an undetermined period of time before attempting to communicate again. This random pause is intended to prevent both devices from trying to re-transmit at once and colliding once more. When two or more devices attempt to send a frame at the same time over half-duplex Ethernet (full-duplex will be discussed below), collisions take place. Each device delays (backs-off) for a random period of time before retrying when frames clash since the frame must be retried. When two devices connected to the same Ethernet network attempt to send data at precisely the same time on a half-duplex Ethernet network, a collision occurs.

what are two actions performed by a cisco switch? (choose two.)
The two actions performed by a cisco switch are: a) building a MAC address table utilizing the source MAC addresses of frames b) using the target MAC address to forward frames using the MAC address table.
A Cisco switch has two modes: forwarding and blocking. Based on the information it possesses, the switch will choose the optimal route for the data to travel when forwarding traffic. This guarantees that data packets are transported fast and effectively to their designated recipient.
If the cisco switch must block traffic, it will do so in accordance with predetermined standards. This can be used to ensure that only authorized users have access to specific network resources or to stop malicious traffic from reaching its target.
A device on a network can only be identified by its MAC address. The switch uses this information to decide where to send data packets. The switch will pass a packet delivered to a given MAC address to the appropriate port so that it can be received by the desired device.
