問題 #148
A technician is planning an equipement installation into a rack in a data center that practices hot aisle/cold aise ventilation. Which of the following directions should the equipement exhaust face when installed in the rack?

• A. Front
• B. Top
• C. Sides
• D. Rear

答案：D

解題說明：
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.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Discusses data center design principles, including hot aisle/cold aisle configurations.
* Cisco Data Center Design Guide: Provides best practices for data center layout and equipment installation.
* Network+ Certification All-in-One Exam Guide: Covers data center environmental controls and ventilation strategies.

問題 #149
A user connects to a corporate VPN via a web browser and is able to use TLS to access the internal financial system to input a time card. Which of the following best describes how the VPN is being used?

• A. Client-to-site
• B. Clientless
• C. Site-to-site
• D. Full tunnel

答案：B

問題 #150
Before using a guest network, an administrator requires users to accept the terms of use Which of the following is the best way to accomplish this goal?

• A. Captive portal
• B. Autonomous access point
• C. WPA2 encryption
• D. Pre-shared key

答案：A

解題說明：
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+ Exam Objectives and official study guides.

問題 #151
A user is unable to navigate to a website because the provided URL is not resolving to the correct IP address.
Other users are able to navigate to the intended website without issue. Which of the following is most likely causing this issue?

• A. Hosts file
• B. Nameserver record
• C. Self-signed certificate
• D. IP helper ANS

答案：A

解題說明：
* Role of the Hosts File:
* The hosts file is a local file on a computer that maps hostnames to IP addresses. It can be used to override DNS resolution by providing a static mapping of a hostname to an IP address.
* Common Issues with the Hosts File:
* If an incorrect IP address is mapped to a hostname in the hosts file, it can cause the computer to resolve the hostname to the wrong IP address. This can lead to navigation issues for specific websites while other users, relying on DNS, do not face the same problem.
* Why Other Options are Less Likely:
* Self-signed certificate:Relates to SSL/TLS and would cause a security warning, not a navigation failure.
* Nameserver record:Affects all users, not just one.
* IP helper:Used to forward DHCP requests and is unrelated to DNS resolution issues.
* Troubleshooting Steps:
* Check the hosts file on the affected user's computer (C:\Windows\System32\drivers\etc\hostson Windows or/etc/hostson Unix/Linux).
* Look for entries that map the problematic hostname to an incorrect IP address and correct or remove them.
