NEW QUESTION # 31
What is a characteristic of IPv4 addresses?

A. Has zero compression rule
B. It is 32 bits long
C. 12 hex-digit notation
D. It is 128 bits long

Answer: B

Explanation:
Explanation
IPv4 or Internet Protocol version 4 is the fourth version of the Internet Protocol that is used to identify and communicate with devices on the Internet. IPv4 uses a 32-bit address space, which means that each IPv4 address consists of 32 binary digits or bits. These bits can be expressed in different notations, such as decimal, hexadecimal, or binary. The most common notation is the dot-decimal notation, which divides the 32 bits into four groups of eight bits, called octets, and separates them by periods. For example, the IPv4 address
172.16.254.1 is equivalent to the binary address 10101100.00010000.11111110.00000001. The 32-bit address space of IPv4 allows for 2^32or 4,294,967,296 possible addresses, but some of them are reserved for special purposes, such as private networks or multicast addresses12345 References: https://en.wikipedia.org/wiki/Internet_Protocol_version_4

NEW QUESTION # 34
Given the 172.16.0.0 255.255.255.0 IP segment, how many IP addresses can be assigned to host and network devices?

A. 0
B. 1
C. 2
D. 3

Answer: A

Explanation:
Explanation
Given the IP segment 172.16.0.0 255.255.255.0, we can calculate the number of IP addresses that can be assigned to host and network devices using the following formula:
Number of IP addresses=232n2
wherenis the number of bits in the network prefix, which is also the number of ones in the subnet mask. In this case, the subnet mask is 255.255.255.0, which in binary is 11111111.11111111.11111111.00000000.
Therefore,n=24. Plugging this into the formula, we get:
Number of IP addresses=232242=282=2562=254
However, this number includes the network address (172.16.0.0) and the broadcast address (172.16.0.255), which cannot be assigned to host and network devices. Therefore, we need to subtract 2 more from the result, which gives us:
Number of IP addresses=2542=252
This means that there are 252 IP addresses that can be assigned to host and network devices in the IP segment
172.16.0.0 255.255.255.0. The answer option that is closest to this number is A, 126.

NEW QUESTION # 35
Which accurately describes the 051 Model?

A. It is a reference model that describes how data communications occur on a network.
B. It is a reference model that is used to convert binary bits into analog signals.
C. It is a reference model that explains how data is created by the application layer.
D. It is a reference model that describes data flow over the network using four layers.

Answer: A

Explanation:
Explanation
The 051 Model is a reference model that describes how data communications occur on a network using five layers: physical, data link, network, transport, and application. The 051 Model is based on the OSI Model, which has seven layers, but it simplifies the presentation and session layers into the application layer. The 051 Model is used to understand the functions and interactions of different network components, such as devices, protocols, and services. Each layer of the 051 Model has a specific role and responsibility in the data communication process, as follows:
* The physical layer defines the electrical and mechanical characteristics of the transmission medium, such as cables, connectors, and signals. It also determines how data is encoded into bits and transmitted over the medium.
* The data link layer defines the rules and methods for accessing and sharing the transmission medium among multiple devices. It also provides error detection and correction mechanisms to ensure reliable data delivery.
* The network layer defines the logical addressing and routing schemes for data packets across different networks. It also provides congestion control and fragmentation/reassembly functions to optimize network performance.
* The transport layer defines the end-to-end communication and reliability services for data segments between applications. It also provides flow control and multiplexing/demultiplexing functions to manage data streams.
* The application layer defines the protocols and services that enable user applications to exchange data over the network. It also provides functions such as encryption, authentication, and compression to enhance data security and efficiency.

NEW QUESTION # 38
What is the binary equivalent of the Hexadecimal number 17?

A. 0
B. 1
C. 2
D. 3

Answer: C

Explanation:
Explanation
To convert a hexadecimal number to a binary number, we need to follow these steps:
* Write down the hexadecimal number and assign a power of 16 to each digit, starting from the rightmost with 16^0.
* Convert each hexadecimal digit to its decimal equivalent by multiplying it with its power of 16.
* Add all the decimal values to get the decimal equivalent of the hexadecimal number.
* Divide the decimal number by 2 repeatedly and write down the remainders from bottom to top.
* The binary number is the sequence of remainders obtained in the previous step.
Let's apply these steps to the hexadecimal number 17:
* 17 = 1 × 16^1 + 7 × 16^0
* 17 = 16 + 7
* 17 = 23 in decimal
* 23 / 2 = 11 with remainder 1
* 11 / 2 = 5 with remainder 1
* 5 / 2 = 2 with remainder 1
* 2 / 2 = 1 with remainder 0
* 1 / 2 = 0 with remainder 1
* The binary number is 10111
Therefore, the binary equivalent of the hexadecimal number 17 is 10111 (option B).

NEW QUESTION # 42
Which condition allows 5Ghz channels to avoid Adjacent Channel Interference?

A. transmit at high power levels
B. transmit at 40 MHz bandwidth
C. transmit at 20 MHz bandwidth
D. transmit at low power levels

Answer: B

Explanation:
Explanation
Adjacent Channel Interference (ACI) is a type of interference that occurs when two or more wireless devices use channels that are close to each other in the same frequency band. ACI reduces the signal quality and throughput of the wireless devices, as they have to compete for the same spectrum and deal with the noise from the neighboring channels12 The 5 GHz band has more non-overlapping channels than the 2.4 GHz band, which means that there is less chance of ACI in the 5 GHz band. However, ACI can still occur in the 5 GHz band if the wireless devices use wider channel bandwidths, such as 40 MHz or 80 MHz, which are supported by 802.11n and 802.11ac standards. Wider channel bandwidths can increase the data rate and performance of the wireless devices, but they also occupy more spectrum and reduce the number of available channels134 Therefore, one condition that allows 5 GHz channels to avoid ACI is to transmit at 20 MHz bandwidth, which is the narrowest channel bandwidth supported by 802.11a/n/ac standards. By transmitting at 20 MHz bandwidth, the wireless devices can use more non-overlapping channels in the 5 GHz band and minimize the impact of ACI. However, this alsomeans that the wireless devices will have lower data rates and performance than using wider channel bandwidths134 Another condition that can help avoid ACI in the 5 GHz band is to use channel bonding, which is a technique that combines two or more adjacent channels into one wider channel. Channel bonding can increase the data rate and performance of the wireless devices, but it also requires careful planning and coordination to avoid overlapping with other wireless devices. Channel bonding can be done with 40 MHz or 80 MHz channel bandwidths, but not with 20 MHz channel bandwidths134 References:

NEW QUESTION # 44
What is considered a Layer 2 component?

A. Switch
B. Transceiver
C. Router
D. UTP cable

Answer: A

Explanation:
Explanation
A switch is a device that operates at the data link layer (Layer 2) of the OSI model. It is responsible for forwarding frames based on the MAC addresses of the source and destination devices. A switch can also perform media access control, VLAN tagging, QoS, and other Layer 2 functions. A router, on the other hand, operates at the network layer (Layer 3) and routes packets based on their IP addresses. A transceiver is a device that converts electrical signals to optical signals and vice versa, and operates at the physical layer (Layer 1). A UTP cable is a type of twisted pair cable that is also used at the physical layer to transmit data.

NEW QUESTION # 47
Which commands can you use to save the switch configuration changes, so they survive a switch reboot?
(Select two.)

A. write memory
B. save memory
C. store memory
D. copy running-config checkpoint startup-config
E. copy running-config checkpoint backup

Answer: A,B

Explanation:
Explanation
To save the switch configuration changes, so they survive a switch reboot, you can use either the write memory or the save memory command. Both commands perform the same function, which is to copy the running configuration to the startup configuration. The running configuration is the current active configuration in the switch's RAM, while the startup configuration is the configuration that is loaded when the switch boots up. By saving the configuration changes to the startup configuration, you ensure that they are preserved after a reboot12. The other commands are not valid for saving the configuration changes. The copy running-config checkpoint backup and copy running-config checkpoint startup-config commands are used to create checkpoints, which are snapshots of the running configuration that can be used to roll back changes in case of errors3. The store memory command does not exist in Aruba switches.
