NEW QUESTION # 51
Move each protocol from the list on the left to the correct TCP/IP model layer on the right.
Note: You will receive partial credit for each correct match.
Answer:
Explanation:
Explanation:
Here's how each protocol aligns with the correct TCP/IP model layer:
* TCP (Transmission Control Protocol): This protocol belongs to the Transport layer, which is responsible for providing communication between applications on different hosts1.
* IP (Internet Protocol): IP is part of the Internetwork layer, which is tasked with routing packets across network boundaries to their destination1.
* FTP (File Transfer Protocol): FTP operates at the Application layer, which supports application and end- user processes. It is used for transferring files over the network1.
* Ethernet: While not a protocol within the TCP/IP stack, Ethernet is associated with the Network Interface layer, which corresponds to the link layer of the TCP/IP model and is responsible for the physical transmission of data1.
The TCP/IP model layers are designed to work collaboratively to transmit data from one layer to another, with each layer having specific protocols that perform functions necessary for the data transmission process1.
* TCP:
* TCP Model Layer: Transport
* Explanation: The Transport layer is responsible for end-to-end communication and error handling. TCP (Transmission Control Protocol) operates at this layer to provide reliable, ordered, and error-checked delivery of data.
* IP:
* TCP Model Layer: Internetwork
* Explanation: The Internetwork layer, also known as the Internet layer, is responsible for logical addressing and routing. IP (Internet Protocol) operates at this layer to route packets across networks.
* FTP:
* TCP Model Layer: Application
* Explanation: The Application layer provides network services to applications. FTP (File Transfer Protocol) operates at this layer to transfer files between computers over a network.
* Ethernet:
* TCP Model Layer: Network
* Explanation: The Network layer, also known as the Link layer in the TCP/IP model, is responsible for physical addressing and access to the physical medium. Ethernet operates at this layer to provide the physical and data link functions.
* Transport Layer: This layer is responsible for providing communication services directly to the application processes running on different hosts. TCP is a core protocol in this layer.
* Internetwork Layer: This layer is responsible for logical addressing, routing, and packet forwarding.
IP is the primary protocol for this layer.
* Application Layer: This layer interfaces directly with application processes and provides common network services. FTP is an example of a protocol operating in this layer.
* Network Layer: In the TCP/IP model, this layer includes both the data link and physical layers of the OSI model. Ethernet is a protocol used in this layer to define network standards and communication protocols at the data link and physical levels.

NEW QUESTION # 52
A user reports that a company website is not available. The help desk technician issues a tracert command to determine if the server hosting the website is reachable over the network. The output of the command is shown as follows:
What can you tell from the command output?
Answer: B
Explanation:
The tracert command output shows the path taken to reach the destination IP address, 192.168.1.10. The command output indicates:
*Hops 1 and 2 are successfully reached.
*Hop 3 times out, meaning the router at hop 3 did not respond to the tracert request. However, this does not necessarily indicate a problem with forwarding packets, as some routers may be configured to block or not respond to ICMP requests.
*Hops 4 and 5 are successfully reached, with hop 5 being the destination IP 192.168.1.10, indicating that the server is reachable.
Thus, the correct answer is C. The server with the address 192.168.1.10 is reachable over the network.
References :=
*Cisco Traceroute Command
*Understanding Traceroute
The tracert command output indicates that the server with the address 192.168.1.10 is reachable over the network. The asterisk (*) at hop 3 suggests that the probe sent to that hop did not return a response, which could be due to a variety of reasons such as a firewall blocking ICMP packets or the router at that hop being configured not to respond to ICMP requests. However, since the subsequent hops (4 and 5) are showing response times, it means that the packets are indeed getting through and the server is reachable12.

NEW QUESTION # 53
Move each cloud computing service model from the list on the left to the correct example on the right Note: You will receive partial credit for each correct answer.
Answer:
Explanation:
Explanation:
* Three virtual machines are connected by a virtual network in the cloud.
* Model: IaaS (Infrastructure as a Service)
* Explanation: IaaS provides virtualized computing resources over the internet, including virtual machines, storage, and networks.
* Users access a web-based graphics design application in the cloud for a monthly fee.
* Model: SaaS (Software as a Service)
* Explanation: SaaS delivers software applications over the internet, typically on a subscription basis, accessible via a web browser.
* A company develops applications using cloud-based resources and tools.
* Model: PaaS (Platform as a Service)
* Explanation: PaaS provides a platform allowing customers to develop, run, and manage applications without dealing with the infrastructure.
* IaaS (Infrastructure as a Service): Provides virtualized hardware resources that customers can use to build their own computing environments.
* PaaS (Platform as a Service): Offers a platform with tools and services to develop, test, and deploy applications.
* SaaS (Software as a Service): Delivers fully functional applications over the internet that users can access and use without managing the underlying infrastructure.

NEW QUESTION # 54
A user initiates a trouble ticket stating that an external web page is not loading. You determine that other resources both internal and external are still reachable.
Which command can you use to help locate where the issue is in the network path to the external web page?
Answer: B
Explanation:
tracert traces each hop along the network path to the destination, revealing where the connection is failing.
NEW QUESTION # 55
You plan to use a network firewall to protect computers at a small office.
For each statement about firewalls, select True or False.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
* A firewall can direct all web traffic to a specific IP address.
* True: Firewalls can be configured to perform Network Address Translation (NAT) and port forwarding, which can direct all web traffic (typically on port 80 and 443) to a specific internal IP address.
* A firewall can block traffic to specific ports on internal computers.
* True: Firewalls can be configured with access control lists (ACLs) or rules to block traffic to specific ports on internal computers, enhancing security by restricting unwanted or harmful traffic.
* A firewall can prevent specific apps from running on a computer.
* False: Firewalls typically control traffic flow and do not prevent specific applications from running on a computer. Application control is usually managed by endpoint security software or application control systems.
* Directing Web Traffic: Firewalls can manage traffic redirection using NAT and port forwarding rules to route web traffic to designated servers or devices within the network.
* Blocking Specific Ports: Firewalls can enforce security policies by blocking or allowing traffic based on port numbers, ensuring that only permitted traffic reaches internal systems.
* Application Control: While firewalls manage network traffic, preventing applications from running typically requires software specifically designed for endpoint protection and application management.
