NEW QUESTION # 183
A customer recently moved into a new office and notices that some wall plates are not working and are not properly labeled Which of the following tools would be best to identify the proper wiring in the IDF?
Answer: A
Explanation:
A toner and probe tool, also known as a tone generator and probe, is used to trace and identify individual cables within a bundle or to locate the termination points of cables in wiring closets and patch panels. It generates a tone that can be picked up by the probe, helping technicians quickly and accurately identify and label wall plates and wiring. This is the best tool for identifying proper wiring in the Intermediate Distribution Frame (IDF).
NEW QUESTION # 184
A network analyst is installing a wireless network in a corporate environment. Employees are required to use their domain identities and credentials to authenticate and connect to the WLAN. Which of the following actions should the analyst perform on the AP to fulfill the requirements?
Answer: C
Explanation:
WPA3-Enterprise provides strong security and supports authentication using domain identities through a RADIUS server and 802.1X authentication. This is the best choice for a corporate environment requiring user- based authentication.
WPA3-Enterprise Benefits:
Uses 802.1X with EAP (Extensible Authentication Protocol) to authenticate users via a directory service (e.g., Active Directory).
Eliminates shared passwords (PSK) for authentication.
Provides strong encryption and resistance to brute-force attacks.
Incorrect Options:
A: Enable MAC Security:
MAC filtering is not secure because MAC addresses can be spoofed.
B: Generate a PSK for Each User:
Pre-shared keys (PSK) are used in WPA-Personal, not in an enterprise setting.
Does not scale well in corporate environments.
C: Implement WPS:
Wi-Fi Protected Setup (WPS) is a vulnerable security method meant for home users.
Not suitable for enterprise authentication.

NEW QUESTION # 185
A network administrator has been taskedwith configuring a network for a newcorporate office. The office consists of twobuildings, separated by 50 feet with nophysical connectivity. The configuration mustmeet the following requirements:
. Devices in both buildings should be
able to access the Internet.
. Security insists that all Internet traffic
be inspected before entering the
network.
. Desktops should not see traffic
destined for other devices.
INSTRUCTIONS
Select the appropriate network device foreach location. If applicable, click on themagnifying glass next to any device whichmay require configuration updates and makeany necessary changes.
Not all devices will be used, but all locationsshould be filled.
If at any time you would like to bring backthe initial state of the simulation, please click the Reset All button.
Answer:
Explanation:
See the step by step complete solution below.
Explanation:
* Devices in both buildings should be able to access the Internet.
* Security insists that all Internet traffic be inspected before entering the network.
* Desktops should not see traffic destined for other devices.
Here is the corrected layout with explanation:
* Building A:
* Switch: Correctly placed to connect all desktops.
* Firewall: Correctly placed to inspect all incoming and outgoing traffic.
* Building B:
* Switch: Not needed. Instead, place aWireless Access Point (WAP)to provide wireless connectivity for laptops and mobile devices.
* Between Buildings:
* Wireless Range Extender: Correctly placed to provide connectivity between the buildings wirelessly.
* Connection to the Internet:
* Router: Correctly placed to connect to the Internet and route traffic between the buildings and the Internet.
* Firewall: The firewall should be placed between the router and the internal network to inspect all traffic before it enters the network.
* Top-left (Building A): Switch
* Bottom-left (Building A): Firewall (inspect traffic before it enters the network)
* Top-middle (Internet connection): Router
* Bottom-middle (between buildings): Wireless Range Extender
* Top-right (Building B): Wireless Access Point (WAP)
Corrected Setup:In this corrected setup, the WAP in Building B will connect wirelessly to the Wireless Range Extender, which is connected to the Router. The Router is connected to the Firewall to ensure all traffic is inspected before it enters the network.
* SSID: CORP
* Security Settings: WPA2 or WPA2 - Enterprise
* Key or Passphrase: [Enter a strong passphrase]
* Mode: [Set based on your network plan]
* Channel: [Set based on your network plan]
* Speed: Auto
* Duplex: Auto
Configuration for Wireless Range Extender:With these settings, both buildings will have secure access to the Internet, and all traffic will be inspected by the firewall before entering the network. Desktops and other devices will not see traffic intended for others, maintaining the required security and privacy.

To configure the wireless range extender for security, follow these steps:
* SSID (Service Set Identifier):
* Ensure the SSID is set to "CORP" as shown in the exhibit.
* Security Settings:
* WPA2orWPA2 - Enterprise: Choose one of these options for stronger security.
WPA2-Enterprise provides more robust security with centralized authentication, which is ideal for a corporate environment.
* Key or Passphrase:
* If you selectWPA2, enter a strong passphrase in the "Key or Passphrase" field.
* If you selectWPA2 - Enterprise, you will need to configure additional settings for authentication servers, such as RADIUS, which is not shown in the exhibit.
* Wireless Mode and Channel:
* Set the appropriate mode and channel based on your network design and the environment to avoid interference. These settings are not specified in the exhibit, so set them according to your network plan.
* Wired Speed and Duplex:
* Set the speed to "Auto" unless you have specific requirements for 100 or 1000 Mbps.
* Set the duplex to "Auto" unless you need to specify half or full duplex based on your network equipment.
* Save Configuration:
* After making the necessary changes, click the "Save" button to apply the settings.
Here is how the configuration should look after adjustments:
* SSID: CORP
* Security Settings: WPA2 or WPA2 - Enterprise
* Key or Passphrase: [Enter a strong passphrase]
* Mode: [Set based on your network plan]
* Channel: [Set based on your network plan]
* Speed: Auto
* Duplex: Auto
Once these settings are configured, your wireless range extender will provide secure connectivity for devices in both buildings.
Firewall setting toto ensure complete compliance with the requirements and best security practices, consider the following adjustments and additions:
* DNS Rule: This rule allows DNS traffic from the internal network to any destination, which is fine.
* HTTPS Outbound: This rule allows HTTPS traffic from the internal network (assuming
192.169.0.1/24 is a typo and should be 192.168.0.1/24) to any destination, which is also good for secure
* web browsing.
* Management: This rule allows SSH access to the firewall for management purposes, which is necessary for administrative tasks.
* HTTPS Inbound: This rule denies inbound HTTPS traffic to the internal network, which is good unless you have a web server that needs to be accessible from the internet.
* HTTP Inbound: This rule denies inbound HTTP traffic to the internal network, which is correct for security purposes.
* Permit General Outbound Traffic: Allow general outbound traffic for web access, email, etc.
* Block All Other Traffic: Ensure that all other traffic is blocked to prevent unauthorized access.
* Correct the Network Typo:
* Ensure that the subnet192.169.0.1/24is corrected to192.168.0.1/24.
* Permit General Outbound Traffic:
* Rule Name: General Outbound
* Source:192.168.0.1/24
* Destination:ANY
* Service:ANY
* Action:PERMIT
* Deny All Other Traffic:
* Rule Name: Block All
* Source:ANY
* Destination:ANY
* Service:ANY
* Action:DENY
Suggested Additional Settings:Firewall Configuration Adjustments:Here is how your updated firewall settings should look:
Rule Name
Source
Destination

These settings ensure that:
* Internal devices can access DNS and HTTPS services externally.
* Management access via SSH is permitted.
* Inbound HTTP and HTTPS traffic is denied unless otherwise specified.
* General outbound traffic is allowed.
* All other traffic is blocked by default, ensuring a secure environment.
Make sure to save the settings after making these adjustments.
NEW QUESTION # 186
A company is expanding to another floor in the same building. The network engineer configures a new switch with the same VLANs as the existing stack. When the network engineer connects the new switch to the existing stack, all users lose connectivity. Which of the following is the MOST likely reason?
Answer: A
Explanation:
This describes aSpanning Tree Protocol (STP) loop. If STP isn't correctly configured or a redundant link is added without STP protection, it causesbroadcast storms and network outages.
* A. Unused ports disabledwould not affect the entire network.
* B. Missing default gatewayon a switch doesn't cause total network loss.
* **C. Connecting a switch to an access port can cause VLAN mismatches, but not total connectivity loss unless a loop forms.
