CompTIA Network+ Certification Exam N10-009 Prüfungsfragen mit Lösungen (Q31-Q36):

31. Frage
A network engineer wants to implement a new IDS between the switch and a router connected to the LAN.
The engineer does not want to introduce any latency by placing the IDS in line with the gateway. The engineer does want to ensure that the IDS sees all packets without any loss. Which of the following is the best way for the engineer to implement the IDS?

A. Use a network tap.
B. Use a protocol analyzer.
C. Use a port mirror.
D. Use Nmap software.

Antwort: C

32. Frage
You are tasked with verifying the following requirements are met in order to ensure network security.
Requirements:
Datacenter
Ensure network is subnetted to allow all devices to communicate properly while minimizing address space usage Provide a dedicated server to resolve IP addresses and hostnames correctly and handle port 53 traffic Building A Ensure network is subnetted to allow all devices to communicate properly while minimizing address space usage Provide devices to support 5 additional different office users Add an additional mobile user Replace the Telnet server with a more secure solution Screened subnet Ensure network is subnetted to allow all devices to communicate properly while minimizing address space usage Provide a server to handle external 80/443 traffic Provide a server to handle port 20/21 traffic INSTRUCTIONS Drag and drop objects onto the appropriate locations. Objects can be used multiple times and not all placeholders need to be filled.
Available objects are located in both the Servers and Devices tabs of the Drag & Drop menu.

33. Frage
A network administrator configured a router interface as 10.0.0.95 255.255.255.240. The administrator discovers that the router is not routing packets to a web server with IP 10.0.0.81/28. Which of the following is the best explanation?

A. Thesubnet is in a private address space.
B. TheIP address spaceis a class A network.
C. Theweb server Is In adifferent subnet.
D. Therouter interface isa broadcast address.

Antwort: D

34. Frage
A network administrator needs to add 255 useable IP addresses to the network. A /24 is currently in use.
Which of the following prefixes would fulfill this need?

A. /29
B. /23
C. /25
D. /32

Antwort: B

Begründung:
A /23 subnet provides 512 total addresses, of which 510 are usable (subtracting 2 for network and broadcast addresses). This would satisfy the need for 255 additional addresses.

35. Frage
An IT manager needs to connect ten sites in a mesh network. Each needs to be secured with reduced provisioning time. Which of the following technologies will best meet this requirement?

A. VXLAN
B. VPN
C. SD-WAN
D. NFV

Antwort: C

Begründung:
* Definition of SD-WAN:
* Software-Defined Wide Area Network (SD-WAN) is a technology that simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. It allows for centralized management and enhanced security.
* Benefits of SD-WAN:
* Reduced Provisioning Time:SD-WAN enables quick and easy deployment of new sites with centralized control and automation.
* Security:Incorporates advanced security features such as encryption, secure tunneling, and integrated firewalls.
* Scalability:Easily scales to accommodate additional sites and bandwidth requirements.
* Comparison with Other Technologies:
* VXLAN (Virtual Extensible LAN):Primarily used for network virtualization within data centers.
* VPN (Virtual Private Network):Provides secure connections but does not offer the centralized management and provisioning efficiency of SD-WAN.
* NFV (Network Functions Virtualization):Virtualizes network services but does not specifically address WAN management and provisioning.
* Implementation:
* SD-WAN solutions are implemented by deploying edge devices at each site and connecting them to a central controller. This allows for dynamic routing, traffic management, and security policy enforcement.
References:
* CompTIA Network+ course materials and networking solution guides.
