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.

Explanation:

The correct matching of the MFA factors to their examples is as follows:

Entering a one-time security code sent to your device after logging in: Possession

Holding your phone to your face to be recognized: Inherence

Specifying your user name and password to log on to a service: Knowledge

Here’s why each factor matches the example:

Possession: This factor is something the user has, like a mobile device. A one-time security code sent to this device falls under this category.

Inherence: This factor is something the user is, such as a biometric characteristic. Facial recognition using a phone is an example of this factor.

Knowledge: This factor is something the user knows, like a password or PIN.

Multi-Factor Authentication (MFA) enhances security by requiring two or more of these factors to verify a user’s identity before granting access.

Entering a one-time security code sent to your device after logging in.

Factor: Possession

This factor relates to something you have, such as a device that receives a security code.

Holding your phone to your face to be recognized.

Factor: Inference (typically referred to as Inherence or Biometric)

This factor relates to something you are, such as biometric authentication like facial recognition.

Specifying your username and password to log on to a service.

Factor: Knowledge

This factor relates to something you know, such as a username and password.

Possession Factor: This involves something the user has in their possession. Receiving a one-time security code on a device (e.g., phone) is an example of this.

Inference Factor (Inherence/Biometric): This involves something inherent to the user, such as

biometric verification (e.g., facial recognition or fingerprint scanning).

Knowledge Factor: This involves something the user knows, such as login credentials (username and password).

Explanation:

Based on the image description provided, here are the cable types matched with the appropriate connection descriptions:

Connects Switch S1 to Router R1 Gi0/0/1 interface Cable Type: = Straight-through UTP Cable

Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit Cable Type: = Fiber Optic Cable

Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1 Cable Type: = Crossover UTP Cable

Connects Switch S3 to Server0 network interface card Cable Type: = Straight-through UTP Cable

The choices are based on standard networking practices where:

Straight-through UTP cables are typically used to connect a switch to a router or a network interface card.

Fiber optic cables are ideal for long-distance, high-speed data transmission, such as connections through an underground conduit.

Crossover UTP cables are used to connect similar devices, such as router-to-router connections.

These matches are consistent with the color-coded cables in the image: green for switch connections, yellow for router-to-router connections within the same rack, and blue for inter-rack connections. The use of these cables follows the Ethernet cabling standards.

Connects Switch S1 to Router R1 Gi0/0/1 interface:

Cable Type: Straight-through UTP Cable

A straight-through UTP cable is typically used to connect different types of devices, such as a switch to a router.

Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit:

Cable Type: Fiber Optic Cable

Fiber optic cables are used for long-distance connections, such as those through an underground conduit between buildings.

Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1:

Cable Type: Crossover UTP Cable

A crossover UTP cable is typically used to connect similar devices directly, such as router to router connections.

Connects Switch S3 to Server0 network interface card:

Cable Type: Straight-through UTP Cable

A straight-through UTP cable is typically used to connect a switch to an end device, such as a server.

Straight-through UTP Cable: Used to connect different devices (e.g., switch to router, switch to server).

Crossover UTP Cable: Used to connect similar devices directly (e.g., router to router, switch to switch).

Fiber Optic Cable: Used for long-distance and high-speed connections, often between buildings or data centers.

Explanation:

The two interfaces are administratively shut down:

False: The output does not show any "shutdown" command under the interfaces, which would indicate that they are administratively shut down. Therefore, they are likely in their default state, which is administratively up.

The two interfaces have default IP addresses assigned:

False: The output does not show any IP address configuration. In the default state, interfaces do not have IP addresses assigned unless explicitly configured.

The two interfaces can communicate over Layer 2:

True: By default, interfaces on a switch are Layer 2 interfaces capable of forwarding Ethernet frames. As there is no configuration provided that changes this, it can be assumed they can communicate over Layer 2.

Interface Status: The absence of the "shutdown" command means the interfaces are not administratively shut down.

IP Address Assignment: There is no evidence in the output that IP addresses have been assigned to the interfaces, which would typically be shown as "ip address" entries.

Layer 2 Communication: Switch interfaces in their default state operate at Layer 2, enabling them to forward Ethernet frames and participate in Layer 2 communication.

Explanation:

To capture packets sent to and received from the URL https://www.companypro.net:7100/api using

Wireshark, you would use the following filter options:

Protocol: tcp

Filter Type: port

Port Number: 7100

This filter setup in Wireshark will display all TCP packets that are sent to or received from port 7100, which is the port specified in the URL for the API service. Since HTTPS typically uses TCP as the transport layer protocol, filtering by TCP and the specific port number will help isolate the relevant packets for troubleshooting the app’s data download issues.

tcp: The app is using HTTPS, which relies on the TCP protocol for communication.

port: The specific port number used by the application, which in this case is 7100.

7100: This is the port specified in the URL (https://www.companypro.net:7100/api).

This filter will capture all TCP traffic on port 7100, allowing you to analyze the packets related to the application’s data download.
