질문 # 538
A new company is assigned a public /24 IP address block by the ISP. The company network is expected to have 1,000 IP-addressable devices. A network engineer is implementing a firewall at the internet edge for security. Which of the following actions should the engineer take to successfully implement IP addresses on the company network?

정답：D

설명：
Using RFC1918 private addressing internally provides enough IP space for 1,000 devices, and configuring NAT on the edge firewall allows those internal private IPs to share the assigned public
/24 for internet access while keeping the internal addressing non-public.


질문 # 539
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?

정답：B

설명：
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.
Reference:
CompTIA Network+ guide detailing security zones and their implementation in a corporate network (see page Ref 9 Basic Configuration Commands).


질문 # 540
An administrator purchases a hypervisor add-on that provides visibility of network traffic between virtual machines. Which of the following best describes this type of traffic?

정답：C

설명：
Traffic between virtual machines within the same environment is referred to as east-west traffic, representing lateral communication inside the network rather than traffic entering or leaving it.


질문 # 541
Which of the following is a cost-effective advantage of a split-tunnel VPN?

정답：C

설명：
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.
Network Reference:
CompTIA Network+ N10-007 Official Certification Guide: Covers VPN types, including split-tunnel configurations and their advantages.
Cisco Networking Academy: Discusses VPN technologies and the benefits of split-tunneling.
Network+ Certification All-in-One Exam Guide: 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.


질문 # 542
Which of the following internal routing protocols is best characterized as having fast convergence and being loop-free?

정답：B

설명：
OSPF is a link-state routing protocol known for its fast convergence and use of the Dijkstra algorithm to calculate the shortest loop-free path. It efficiently scales to large enterprise networks and avoids routing loops by maintaining a complete topology map.
