Move each protocol from the list on the left to its correct example on the right.
正解：
解説：
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.

A Cisco switch is not accessible from the network. You need to view its running configuration.
Which out-of-band method can you use to access it?
正解：B
解説：
When a Cisco switch is not accessible from the network, the recommended out-of-band method to access its running configuration is through the console port. Out-of-band management involves accessing the network device through a dedicated management channel that is not part of the data network. The console port provides direct access to the switch's Command Line Interface (CLI) without using the network, which is essential when the switch cannot be accessed remotely via the network12.

質問 # 55
A help desk technician receives a report that a user is experiencing network connectivity issues.
The help desk supervisor advises the technician to use a bottom-up troubleshooting method to determine the cause of the problem.
Which two potential issues would the technician check first using the bottom-up method?
(Choose two.)
正解：A、E
解説：
The bottom-up troubleshooting method begins at the physical layer, so the first checks focus on hardware and connectivity media. A failed network interface card and incorrect or damaged cables are both physical-layer problems that should be verified before moving up to configuration or service-related causes.
質問 # 56
Evaluate the graphic.
While making a configuration change to Router1, a junior technician accidentally reboots the router.
Which two statements are true about the impact to communication on the network while the router is temporarily offline? (Choose two.)
正解：A、D
解説：
Communication between different VLANs requires Router1, so without the router, no PC can reach the file server in VLAN 10. Devices in the same VLAN can still communicate at Layer 2 through the switch, so PC-A and PC-B can still communicate with each other.
質問 # 57
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.
正解：
解説：
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
* Explanation: 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)
* Explanation: 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
* Explanation: 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).
