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 a Wireless 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.
Corrected Setup:
* 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)
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.
Configuration for Wireless Range Extender:
* 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
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:
* WPA2 or WPA2 - 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 select WPA2, enter a strong passphrase in the "Key or Passphrase" field.
* If you select WPA2 - 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 to to 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.
Suggested Additional Settings:
* 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.
Firewall Configuration Adjustments:
* Correct the Network Typo:
* Ensure that the subnet 192.169.0.1/24 is corrected to 192.168.0.1/24.
* 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
Here is how your updated firewall settings should look:
Rule Name
Source
Destination
Service
Action
DNS Rule
192.168.0.1/24
ANY
DNS
PERMIT
HTTPS Outbound
192.168.0.1/24
ANY
HTTPS
PERMIT
Management
ANY
192.168.0.1/24
SSH

HTTPS Inbound
ANY
192.168.0.1/24
HTTPS
DENY
HTTP Inbound
ANY
192.168.0.1/24
HTTP
DENY
General Outbound
192.168.0.1/24
ANY
ANY
PERMIT
Block All
ANY
ANY
ANY
DENY
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 # 131
Which of the following devices can operate in multiple layers of the OSI model?

A. Switch
B. Transceiver
C. Modem
D. Hub

Answer: A

Explanation:
* Understanding Switches:
* Layer 2 (Data Link Layer):Traditional switches operate primarily at Layer 2, where they use MAC addresses to forward frames within a local network.
* Layer 3 (Network Layer):Layer 3 switches, also known as multilayer switches, can perform
* routing functions using IP addresses to forward packets between different networks.
* Capabilities of Multilayer Switches:
* VLANs and Inter-VLAN Routing:Multilayer switches can handle VLAN (Virtual Local Area Network) configurations and perform inter-VLAN routing, enabling communication between different VLANs.
* Routing Protocols:They can run routing protocols like OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol) to manage traffic between networks.
* Comparison with Other Devices:
* Hub:Operates only at Layer 1 (Physical Layer) and simply repeats incoming signals to all ports.
* Transceiver:Also operates at Layer 1, converting electrical signals to optical signals and vice versa.
* Modem:Primarily operates at Layer 1 and Layer 2, modulating and demodulating signals for transmission over different types of media.
* Practical Application:
* Multilayer switches are commonly used in enterprise networks to optimize performance and manage complex routing and switching requirements within a single device.

A. Ifconfig
B. Dig
C. nmap
D. Ping

Answer: C

NEW QUESTION # 133
A network administrator wants to implement security zones in the corporate network to control access to only individuals inside of the corporation. Which of the following security zones is the best solution?

A. Extranet
B. Public
C. Trusted
D. VPN

Answer: C

Explanation:
* Introduction to Security Zones:
* Security zones are logical segments within a network designed to enforce security policies and control access. They help in segregating and securing different parts of the network.
* Types of Security Zones:
* Trusted Zone: This is the most secure zone, typically used for internal corporate networks where only trusted users have access.
* Extranet: This zone allows controlled access to external partners, vendors, or customers.
* VPN (Virtual Private Network): While VPNs are used to create secure connections over the internet, they are not a security zone themselves.
* Public Zone: This zone is the least secure and is typically used for public-facing services accessible by anyone.
* Trusted Zone Implementation:
* The trusted zone is configured to include internal corporate users and resources. Access controls, firewalls, and other security measures ensure that only authorized personnel can access this zone.
* Internal network segments, such as the finance department, HR, and other critical functions, are usually placed in the trusted zone.
* Example Configuration:
* Firewall Rules: Set up rules to allow traffic only from internal IP addresses.
* Access Control Lists (ACLs): Implement ACLs on routers and switches to restrict access based on IP addresses and other criteria.
* Segmentation: Use VLANs and subnetting to segment and isolate the trusted zone from other zones.
* Explanation of the Options:
* A. Extranet: Suitable for external partners, not for internal-only access.
* B. Trusted: The correct answer, as it provides controlled access to internal corporate users.
* C. VPN: A method for secure remote access, not a security zone itself.
* D. Public: Suitable for public access, not for internal corporate users.
* Conclusion:
* Implementing a trusted zone is the best solution for controlling access within a corporate network. It ensures that only trusted internal users can access sensitive resources, enhancing network security.
