Cameras are the best tool for remotely monitoring who is accessing a secure data center. They provide real-time visual verification of individuals entering and exiting the facility and can be monitored remotely to ensure security protocols are followed. Access control vestibules, employee training, and biometrics are also important for security but do not offer the same continuous, visual monitoring capability that cameras do. Cameras also serve as a deterrent to unauthorized access and can provide forensic evidence in the event of a security breach​​.

• The question asks about the best method to use for the network team to receive UPS status notifications after a critical power issue. The UPS is an uninterruptible power supply that provides backup power to the network devices in case of a power outage or surge1.
• The answer is traps, which are unsolicited messages that are sent from an agent to a manager to notify about an event or a condition that requires attention2. Traps can be used to alert the network team about the UPS status changes, such as battery level, load, temperature, or power failure3.
• MB, NetFlow, and Syslog are not the correct answers, because they are not the best methods to use for the UPS status notifications. MB stands for megabyte, which is a unit of data storage4. NetFlow is a protocol that collects and analyzes network traffic data. Syslog is a standard for logging and monitoring system events. These methods are not designed to send alerts about the UPS status changes, and they may not be reliable or timely in case of a critical power issue. References:

QoS stands for Quality of Service, which is a feature that allows you to prioritize network traffic based on the type of traffic, such as voice, video, data, or gaming. QoS can help improve the performance and reliability of critical applications by allocating more bandwidth and lower latency to them, while reducing the impact of less important or non-essential traffic1.

VPN stands for Virtual Private Network, which is a technology that creates a secure and encrypted connection between two or more devices over the Internet. VPN can help protect your privacy and data from hackers, ISPs, and government surveillance, as well as access geo-restricted content and services2.

CDN stands for Content Delivery Network, which is a network of servers that deliver web content to users based on their geographic location, the origin of the content, and the performance of the network. CDN can help improve the speed and availability of web content, such as images, videos, and scripts, by caching them on servers closer to the users3.

TTL stands for Time To Live, which is a value that determines how long a packet can stay in a network before it is discarded or returned. TTL can help prevent network congestion and loops by limiting the lifespan of packets that are lost, corrupted, or delayed4.

NIC Teaming, also known as load balancing and failover (LBFO), allows multiple network adapters on a computer to be placed into a team for the following purposes: (https://www.bing.com/search?q=what+is+nic+teaming+used+for%3F &form=QBLH&sp=-1&pq=what+is+nic+teaming+used+for&sc=10-28&qs=n&sk=&cvid=13882A9A9B584D8099F4ABCAD034E821&ghsh=0&ghacc=0&ghpl=)
