What component of a blade enclosure is a printed circuit board with server blades on one side connected to other components such as networking interfaces on the other side?

  • Midplane

  • Frontplane

  • Backplane

  • Hybrid plane

Correct answer: Midplane

Midplanes are often used in blade servers, where the server blades reside on one side and the peripheral components such as power, networking, and other I/O reside on the other. Midplanes are also used in networking and telecommunications equipment, where one side of the blade connects system processing components and the other side of the blade connects network interface cards.

170.

TCP is a connection oriented protocol. A TCP session is established and confirmed between two communicating devices before transmitting data by completing a 3-step handshake. What is the second step in the handshake?

  • SYN ACK

  • ACK

  • SYN

  • SYN NACK

Correct answer: SYN ACK

When the server receives the SYN packet from the first step in the handshake, it responds and returns a SYN ACK confirmation receipt, which has two sequence numbers. The sequence numbers indicate that the server correctly acknowledged the client’s packet, and that it is sending its own to be acknowledged as well.

171.

What storage speed factor refers to how often a disk can perform input/output operations?

  • IOPS

  • IOPM

  • IOPH

  • IOPO

Correct answer: IOPS

Input/output operations per second (IOPS) is used to measure the performance of a storage device. IOPS indicates how many input or output operations a device can perform in one second.

Input/output operations per minute, hour, and operation (IOPM, IOPH, and IOPO) are fabricated terms.

172.

Which Windows administrator command is used most frequently for troubleshooting DHCP server issues?

  • ipconfig /all

  • arp -a

  • iplookup /all

  • ipconfig /resolve

Correct answer: ipconfig /all

The ipconfig (short for IP Configuration) is a basic and informative Windows network command-line command. It is used to display the TCP/IP network configuration of a computer, which assists in troubleshooting network connectivity and IP address resolution issues.

173.

What is the name of the assigned router on a LAN through which hosts send traffic leaving the LAN to the internet?

  • Default gateway

  • Primary router

  • Edge gateway

  • Primary gateway

Correct answer: Default gateway

A default gateway makes it possible for devices in one network to communicate with devices in another network. If a computer requests a web page, the request goes through the default gateway before exiting the local network to reach the internet. A default gateway is an intermediate device between the local network and the internet.

An edge gateway typically connects IoT devices to the cloud.

Primary router and gateway are fabricated terms.

174.

A rack-mounted server is a computer designed to be installed in a frame called a rack. The rack contains multiple mounting slots called bays, and each bay holds a hardware unit secured in place with screws. Rack-mounted servers are smaller and more space-efficient than standalone or tower servers.

Blade-centered is a fabricated term that seems like what blade servers might be called.

177.

Edge devices are the first point of contact for users and could be compromised. What type of central authentication authority is used to forward edge device authentication requests?

  • RADIUS

  • HTTPS

  • NAC

  • DHCP

Correct answer: RADIUS

Remote Authentication Dial-In User Service (RADIUS) is a protocol and software that enables edge devices to communicate with a central server to authenticate users and authorize their access to the requested system or service. RADIUS maintains user profiles in a central database that all remote servers can share. This provides better security because policies are applied at a single administered network point.

178.

Which layer of the OSI model is responsible for managing bridges, switches, and network interface cards?

  • Data link

  • Session

  • Transport

  • Physical

 Correct answer: Data link

The data link layer is responsible for the node-to-node delivery of the message. The main function of this layer is to make sure data transfer is error-free from one node to another over the physical layer. When a packet arrives in a network, it is the responsibility of the data link layer to transmit it to the destination host using its MAC address.
