HTTP

NO.23 Examine the connections shown in the following image. Move the cable types on the right to the appropriate connection description on the left. You may use each cable type more than once or not at all.

NO.24 DRAG DROP
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.

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
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
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
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
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.

NO.28 Computers in a small office are unable to access companypro.net. You run the ipconfig command on one of the computers. The results are shown in the exhibit.
You need to determine if you can reach the router.

Which command should you use? Complete the command by selecting the correct options from each drop- down lists.

NO.29 Which command will display all the current operational settings configured on a Cisco router?

show protocols

show startup-config

show version

show running-config

NO.30 DRAG DROP
Move each protocol from the list on the left to its correct example on the right.

Explanation:
The correct matching of the protocols to their examples is as follows:
DHCP: Assign the reserved IP address 10.10.10.200 to a web server at your company.
DNS: Perform a query to translate companypro.net to an IP address.
ICMP: Perform a ping to ensure that a server is responding to network connections.
Here’s how each protocol corresponds to its example:
DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to devices on a network.
In this case, DHCP would be used to assign the reserved IP address 10.10.10.200 to a web server.
DNS (Domain Name System) is used to translate domain names into IP addresses. Therefore, to translate companypro.net to an IP address, DNS would be utilized.
ICMP (Internet Control Message Protocol) is used for sending error messages and operational information indicating success or failure when communicating with another IP address. An example of this is using the ping command to check if a server is responding to network connections.
These protocols are essential for the smooth operation of networks and the internet.
Perform a query to translate companypro.net to an IP address.
DNS (Domain Name System): DNS is used to resolve domain names to IP addresses.
Assign the reserved IP address 10.10.10.200 to a web server at your company.
DHCP (Dynamic Host Configuration Protocol): DHCP is used to assign IP addresses to devices on a network.
Perform a ping to ensure that a server is responding to network connections.
ICMP (Internet Control Message Protocol): ICMP is used by network devices to send error messages and operational information, and it is the protocol used by the ping command.
DNS (Domain Name System): DNS translates human-friendly domain names like “companypro.net” into IP addresses that computers use to identify each other on the network.
DHCP (Dynamic Host Configuration Protocol): DHCP automatically assigns IP addresses to devices on a network, ensuring that no two devices have the same IP address.
ICMP (Internet Control Message Protocol): ICMP is used for diagnostic or control purposes, and the ping command uses ICMP to test the reachability of a host on an IP network.

NO.31 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?

The router at hop 3 is not forwarding packets to the IP address 192.168.1.10.

The server address 192.168.1.10 is being blocked by a firewall on the router at hop 3.

The server with the address 192.168.1.10 is reachable over the network.

Requests to the web server at 192.168.1.10 are being delayed and time out.

NO.32 DRAG DROP
Move the MFA factors from the list on the left to their correct examples on the right. You may use each factor once, more than once, or not at all.
Note: You will receive partial credit for each correct selection.

NO.33 Which two statements are true about the IPv4 address of the default gateway configured on a host? (Choose 2.) Note: You will receive partial credit for each correct selection.

The IPv4 address of the default gateway must be the first host address in the subnet.

The same default gateway IPv4 address is configured on each host on the local network.

The default gateway is the Loopback0 interface IPv4 address of the router connected to the same local network as the host.

The default gateway is the IPv4 address of the router interface connected to the same local network as the host.

Hosts learn the default gateway IPv4 address through router advertisement messages.
