NEW QUESTION # 19
How many IP assignable addresses are contained in 10.0.128.0/23?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Explanation
The IP address 10.0.128.0/23 is a Class A private address with a subnet mask of 255.255.254.0. This means that the network prefix is 10.0.128.0 and the host identifier is the last 9 bits of the address. To find the number of IP assignable addresses, we need to subtract 2 from the total number of possible hosts, which is29=512.
This is because the network address (10.0.128.0) and the broadcast address (10.0.129.255) are reserved and cannot be assigned to any host. Therefore, the number of IP assignable addresses is 512 - 2 =

NEW QUESTION # 21
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: B
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 # 22
Which protocols operate on the Management Plane? (Select two.)
- A. Address Resolution Protocol
- B. Transmission Control Protocol
- C. Spanning Tree Protocol
- D. Secure Shell
- E. Hypertext Transfer Protocol Secure
Answer: D,E
Explanation:
Explanation
The management plane is the logical path of all traffic related to the management of the device. Examples of protocols processed in the management plane are Simple Network Management Protocol (SNMP), Telnet, HTTP, Secure HTTP (HTTPS), and SSH. These management protocols are used for monitoring and for command-line interface (CLI) access12. Therefore, HTTPS and SSH are protocols that operate on the management plane, while the other options are not. TCP is a transport layer protocol that provides reliable data delivery for various applications, but it is not specific to the management plane3. ARP is a network layer protocol that resolves IP addresses to MAC addresses, but it is not used for device management4. STP is a data link layer protocol that prevents loops in switched networks, but it is not related to the management plane5.

NEW QUESTION # 24
Which protocol provides logical addressing used for routing messages across the network towards their destination?
- A. Transmission Control Protocol
- B. Wired Ethernet
- C. Link Layer Discovery Protocol
- D. Internet Protocol
Answer: D
Explanation:
Explanation
The protocol that provides logical addressing used for routing messages across the network towards their destination is the Internet Protocol (IP). IP is a network layer protocol that assigns a unique numerical identifier to each device on a network, called an IP address. IP addresses are used to identify the source and destination of data packets, and to determine the best path to deliver them. IP is a connectionless and best-effort protocol, meaning that it does not guarantee the delivery, order, or integrity of the packets. IP relies on other protocols, such as TCP, to provide reliable and orderly data transfer.
The other options are incorrect because:
B: Transmission Control Protocol (TCP) is a transport layer protocol that provides reliable and orderly data delivery by establishing a connection between devices and providing error-checking and retransmission mechanisms. TCP does not provide logical addressing or routing functions, but it uses IP addresses to identify the endpoints of a connection.
C: Wired Ethernet is a data link layer protocol that defines the physical and logical characteristics of a wired network, such as cable types, frame formats, and MAC addresses. MAC addresses are used to identify the physical devices on a network segment, but they are not used for routing messages across the network.
Ethernet does not provide logical addressing or routing functions, but it relies on IP to do so.
D: Link Layer Discovery Protocol (LLDP) is a data link layer protocol that allows devices to discover and advertise information about themselves and their neighbors on a network, such as device type, capabilities, port configuration, and VLAN membership. LLDP does not provide logical addressing or routing functions, but it can help network administrators to troubleshoot and optimize the network topology. References:

NEW QUESTION # 27
What is considered a Layer 2 component?
- A. Transceiver
- B. Router
- C. UTP cable
- D. Switch
Answer: D
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 # 28
Which characteristic allows switches to mitigate collisions?
- A. The switches have proprietary features that help eliminate collisions.
- B. The switches use L3 protocols that eliminate collisions.
- C. The switches' ports are independent collision domains.
- D. The switches support VLANs that segment the collision domains.
Answer: D
NEW QUESTION # 29
Which configurable switchport feature makes collisions impossible to occur?
- A. half-duplex
- B. full-duplex
- C. VLANs
- D. auto speed
Answer: B
Explanation:
Explanation
Full-duplex is a switchport feature that allows simultaneous transmission and reception of data on a link, without causing collisions. Collisions occur when two devices try to send data at the same time on a shared medium, such as a half-duplex link or a hub. Full-duplex eliminates the need for collision detection and avoidance mechanisms, such as CSMA/CD, and increases the effective bandwidth of the link. Full-duplex requires both ends of the link to support and be configured for full-duplex mode. If one end is configured for full-duplex and the other for half-duplex, the result is a duplex mismatch, which causes performance issues and errors. Auto speed is a switchport feature that allows the switch to negotiate the speed of the link with the connected device, such as 10 Mbps, 100 Mbps, or 1000 Mbps. VLANs are logical groups of devices that share the same broadcast domain, regardless of their physical location or connection. VLANs can reduce collisions by segmenting the network and limiting the scope of broadcasts. However, VLANs alone do not prevent collisions on a link, as they depend on the duplex mode of the switchport. Half-duplex is a switchport feature that allows only one direction of data transmission at a time on a link, either sending or receiving. Half-duplex requires collision detection and avoidance mechanisms, such as CSMA/CD, to coordinate the access to the shared medium. Half-duplex reduces the effective bandwidth of the link by half, as only one device can use the link at a time. Half-duplex can cause collisions if two devices try to send data at the same time on the same link. References:

NEW QUESTION # 30
What are the differences between Local-based and Server-based management? (Select two.)
- A. in local-based, the managed device is a client, while in server-based it is a server
- B. server-based management can monitor multiple devices at once, local-based cannot
- C. server-based management cannot talk to the device's control plane, local-based can
- D. local-based management requires an on-premises network management appliance
- E. local-based management can use the device's console port, server-based cannot
Answer: B,E
Explanation:
Explanation
Local-based management refers to managing a network device directly from the device itself, using tools such as console port, web interface, or command-line interface. Server-based management refers to managing a network device remotely from a centralized server, using tools such as Windows Admin Center, System Center, or Azure Arc123. The differences between these two types of management are:
* Local-based management can use the device's console port, which is a physical connection that allows access to the device even when the network is down or the device is not configured. Server-based management cannot use the console port, as it relies on network connectivity and protocols4.
* Server-based management can monitor multiple devices at once, using a single dashboard or interface that shows the status, performance, and configuration of all the devices in the network. Local-based management can only monitor one device at a time, using the device's own tools123.

NEW QUESTION # 31
How many addresses does the 255.255.252.0 provide?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Explanation
The subnet mask 255.255.252.0 is equivalent to the CIDR notation /22, which means that 22 bits are used for the network prefix and 10 bits are used for the host part. To calculate the number of addresses that this subnet mask provides, we can use the formula2n2, wherenis the number of bits in the host part. In this case,n=10, so the number of addresses is2102=10242=1022. The subtraction of 2 is because the first and the last addresses are reserved for the network identifier and the broadcast address, respectively. Therefore, the subnet mask
255.255.252.0 provides 1022 usable addresses for hosts, plus 2 reserved addresses, for a total of 1024 addresses.References:IP Subnet Calculator,How many host addresses are available on the network ... - ITExamAnswers
NEW QUESTION # 32
Refer to Exhibit.
The PCs are not able to successfully establish bidirectional communication. What change must you deploy to enable the communication between PC-1 and PC-2?
- A. change PC-2's default gateway to 172.16.31.254
- B. change PC-1's IP address to 172.16.30.10
- C. change the Router's 1/1/1 interface IP to 172.16.30.254
- D. change PC-1 's default gateway to 172.16.30.2
Answer: A
Explanation:
Explanation
The PCs are not able to successfully establish bidirectional communication because they are on different subnets and their default gateways are not configured correctly. The default gateway is the IP address of the router interface that connects to the same subnet as the PC. The default gateway allows the PC to send packets to destinations outside its own subnet. In this case, PC-1 and PC-2 are on the 172.16.30.0/24 and
172.16.31.0/24 subnets respectively, and the router interfaces are 172.16.30.254 and 172.16.31.254 respectively. Therefore, the correct default gateway for PC-1 is 172.16.30.254 and the correct default gateway for PC-2 is 172.16.31.254. Changing PC-2's default gateway to 172.16.31.254 will enable the communication between PC-1 and PC-212 References:
