Which of the following is the height of 1U of space in a server rack?
1U of space in a server rack is defined as 1.75 inches (4.4 cm) in height. This is the standardized measurement used to ensure compatibility and consistency across different server racks and rack-mounted equipment.
A server technician is replacing a web server in an organization. The new server has two integrated NICs. Which of the following describes how the NICs should be configured for fault protection?
A server with two integrated NICs should have the NICs placed into a team with two MAC addresses for fault protection. NIC teaming (or bonding) allows the NICs to work together as a single logical interface, providing both redundancy and increased bandwidth. If one NIC fails, the other can continue to handle network traffic, ensuring continuous operation. Additionally, having two MAC addresses helps in maintaining proper network communication and load balancing, which are crucial for fault tolerance.
Which of the following provides two-factor authentication?
Two-factor authentication (2FA) involves combining two different types of factors from the following categories: something you know (knowledge), something you have (possession), and something you are (inheritance). A bank card is something you have, and a PIN is something you know, making the combination of both two-factor authentication. Username and password both fall under something you know and thus do not qualify as 2FA. Fingerprint and iris scan both fall under something you are, making them a single factor. Key and proximity badge both represent something you have, also making them a single factor. Therefore, the correct choice is Bank card and PIN.
A server technician is performing a server installation. This server must be able to resolve host names for users running a variety of client operating systems. At a minimum, which of the following services should be enabled on the new server? (Select TWO).
To resolve host names for users running a variety of client operating systems, the services required are DNS and WINS. DNS (Domain Name System) is critical for resolving host names to IP addresses, which is essential for almost all modern network devices and operating systems. WINS (Windows Internet Name Service) is needed for network environments where older Windows systems require name resolution of NetBIOS names to IP addresses. Though WINS is not as commonly used today, it remains a requirement for full compatibility with legacy systems.
A technician is troubleshooting an issue with a new server, which is unable to download OS patches from the Internet. The technician reviews the following configuration:
Ethernet Adapter Local Area Connection:
Connection-specific DNS Suffix . : comptia.org
Link-local IPv6 Address . . . . : fe80::c95:3f59:1a01:c050%11
IPv4 Address . . . . . . . . . . : 192.168.10.20
Subnet Mask . . . . . . . . . . : 255.255.255.128
Default Gateway . . . . . . . . : 192.168.10.129
Which of the following is the reason that the server is unable to connect to the Internet?
The server has an incorrect default gateway. The default gateway of 192.168.10.129 does not fall within the subnet range of the given IP address 192.168.10.20 with the subnet mask 255.255.255.128. The correct default gateway should be an address that falls within this IP range, such as 192.168.10.1.
