N10-009 Online Practice Questions and Answers

Correct Answer: A

See the step by step complete solution below. 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

Building A:

uk.co.certification.simulator.questionpool.PList@180bf167 Building B:

Between Buildings:

Connection to 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): uk.co.certification.simulator.questionpool.PList@8dcd0d6 Security Settings: Key or Passphrase: Wireless Mode and Channel: Wired Speed and Duplex: Save Configuration: 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: uk.co.certification.simulator.questionpool.PList@4f9b9863 Permit General Outbound Traffic: Deny All Other Traffic: 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 PERMIT 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.

Correct Answer: D

A split-tunnel VPN allows some traffic to be routed through the VPN while other traffic goes directly to the internet. This setup offers several advantages, with a primary one being cost-effectiveness due to cloud-based traffic not consuming

company bandwidth.

Bandwidth Utilization: Split-tunnel VPNs reduce the amount of traffic passing through the company's network, freeing up bandwidth for other uses. Performance: By allowing internet-bound traffic to bypass the VPN, it can reduce latency and

improve the performance for users accessing cloud services directly. Cost Savings: Reduced load on the company's VPN infrastructure can lead to lower costs in terms of both hardware and bandwidth.

Certification All-in-One uide: Provides detailed information on VPN setups, including the cost-effectiveness of split-tunnel VPNs. By allowing cloud-based traffic to flow outside the company's network, a split-tunnel VPN optimizes

resource usage and enhances the overall network performance without incurring extra costs for bandwidth.

Correct Answer: D

In a data center that practices hot aisle/cold aisle ventilation, equipment should be installed so that the exhaust faces the rear of the rack. This setup ensures that hot air is expelled into the hot aisle, maintaining proper airflow and cooling

efficiency. Hot Aisle/Cold Aisle Configuration: Equipment intake should face the cold aisle where cool air is supplied, and exhaust should face the hot aisle where hot air is expelled. Cooling Efficiency: Proper orientation of equipment helps

maintain an efficient cooling environment by segregating hot and cold air, preventing overheating and improving energy efficiency.

Correct Answer: B

When installing multiple Power over Ethernet (PoE) devices like security cameras, it is crucial to ensure that the total power requirement does not exceed the power budget of the PoE switch. Each PoE switch has a maximum power capacity,

and exceeding this capacity can cause some devices to fail to receive power. PoE Standards: PoE switches conform to standards such as IEEE 802.3af (PoE) and 802.3at (PoE+), each with specific power limits per port and total power

capacity.

Power Calculation: Adding up the power requirements of all connected PoE devices can help determine if the total power budget of the switch is exceeded. Symptoms: When the power budget is exceeded, some devices, typically those

farthest from the switch or connected last, may not power up or function correctly.

Correct Answer: C

A captive portal is a web page that users must view and interact with before being granted access to a network. It is commonly used in guest networks to enforce terms of use agreements. When a user connects to the network, they are redirected to this portal where they must accept the terms of use before proceeding. This method ensures that users are aware of and agree to the network's policies, making it the best choice for this scenario. References: CompTIA Network
