Services & Virtualization
This service translates human-readable domain names into IP adresses
What is DNS
This command-line tool is used to test basic connectivity between two hosts
what is ping?
This is a wireless site survey perfromed without visiting the physical site, using blueprins and software instead.
What is a predictive analysis
This subnet mast corresponds to a CIDR notation of /26
what is 255.255.255.192
This layer is responsible for routing packets across different networks using logical addressing like IP.
What is the Network Layer (Layer 3)
This cloud service model provides the consumer with the most control, including the OS and storage (E.g., AWS EC2)
What is IaaS
This tool is used to find the distance to a break in a fiber optic cable.
What is an OTDR
This feature allows a wireless client to stay connected while moving from one Access point to another
What is Roaming
This is the decimal value of an 8-bit octet where all bits are set to 1
What is 255
Unlike TCP, this transport layer protocol is connection less and does not guarantee delivery.
What is UDP
This network service automatically assigns IP addresses, subnet mask, and gateways to clients.
What is DHCP
This harware tool is used to "trace" a cable from a wall jack back to a messy patch panel by using a tone generator.
What is a Tone Generator and Probe?
This 802.11 standard was the first to operate exclusively in the 5 GHz range and supported speeds up to 54 Mbps.
What is 802.11a
This Ip address, 127.0.0.1 is used by a host to test its own network stack
What is the loopback adress
This is the Protocol data Unit (PDU) found at layer 2 of the OSI model.
What is a frame
This cloud model is a combination of both private and public cloud infrastructures.
What is Hybrid Cloud?
This Windows command shows the path a packet takes to reach it destination, listing every router along the way.
What is tracert
This tech allows a wireless access point to use multiple antennas to transmit an receive data simultaneously.
What is MIMO
If a device cannot reach a HCP server, it may self-assign an address in the 169.254.0.0/16 range, known as this.
What is APIPA
This PDU is associated with Layer 4 (transport) When using the TCP Protocol
What is a segment
This type of hypervisor runs directly on the "bare metal" hardware without an underlying OS.
What is a Type 1 Hypervisor?
this is a small hardware plug used to trick a NIC into thinking it has a physical link for diagnostic purpouses.
What is a loopback plug?
This wireless frequency band ofers 11 channels in the US (3 non-ovrlapping) but suffers from high interface
What is the 2.4 GHz Band
This is the private IP address range for Class B networks according to RFC 1918
What is 172.16.0.0 to 172.31.255.255
This Protocol operates on port 443 and provides encrypted communication for web traffic
What is HTTPS
