CompTIA Network+ N10-009 Exam Dumps

Comprehensive and Detailed Explanation:

If aping to 10.0.100.19 is unreachable, themost likely issueis that users areon the wrong subnetand cannot communicate with the server.

Breakdown of Options:

A. The users are on the wrong subnet.✅Correct answer.If users are ona different subnetwithout proper routing,they won't reach the server.

B. The DHCP server renewed the lease.– Wouldchange the client’sIP, but the server’sstatic IP should remain unchanged.

C. The IP address was not reserved.– DHCP reservations matter fordynamic IPs, but RDP serverstypically have static IPs.

D. The hostname was changed.– Would affectDNS resolution, butpinging the IP directly would still work.

The most likely reason an insurance brokerage would enforce VPN usage is to encrypt sensitive data in transit. VPNs (Virtual Private Networks) create a secure tunnel between the user's device and the corporate network, ensuring that data is encrypted and protected from interception.

Encryption: VPNs encrypt data, preventing unauthorized access and ensuring data privacy during transmission over public or unsecured networks.

Data Protection: Essential for industries handling sensitive information, such as insurance brokerages, to protect customer data and comply with regulatory requirements.

Security: Enhances overall network security by providing secure remote access for employees.

•A. Isolate smart devices to their own network segment: Network segmentation using VLANs or separate SSIDs ensures that smart devices (like speakers) are not on the same network as guests, preventing unauthorized control.

•E. Change the default credentials: Many IoT devices (e.g., smart speakers) come with default usernames and passwords. If these are not changed, unauthorized users can easily take control.

•Why not the other options?

•B. Configure IPS: IPS (Intrusion Prevention System) detects threats but cannot block specific guest actions on an IoT device.

•C. Install a new AP: A new access point does not solve the unauthorized control issue.

•D. Set up a syslog server: Helps with logging, but does not prevent unauthorized access.

•F. Configure GRE: Generic Routing Encapsulation (GRE) is used for VPN tunneling, which is irrelevant in this case.
