The OSI Model & Protocols
This layer is responsible for routing packets across different networks using logical addressing like IP
What is the Network Layer (Layer 3)?
The standard 8-pin connector used for most twisted pair Ethernet cables.
What is RJ-45
This IP address, 127.0.0.1 is used by hosts to test its own network stack.
What is the Loopback address.
This is the name given to the unique ID or name of a wireless network.
What is SSID?
This security device inspects incoming and outgoing traffic to block unauthorized access based on a set of rules.
What is a Firewall?
This protocol operates on Port 443 and provides encrypted communication for web traffic.
This cable type is required in air-handling spaces because it does not give off toxic fumes when burned.
What is Plenum-rated cables?
What is the Loopback address.
This technology allows wireless access point to use multiple antennas to transmit and receive data simulatneously.
What is MIMO.
This type of attack floods a network with traffic from multiple sources to make a service unavailable.
What is a DDoS (Distributed denial of service?)
Unlike TCP, this transport layer protocol is connectionless and does not guarantee delivery.
What is UDP?
This type of interference occurs when electrical signs from one wire pair leak into an adjacent pair.
What is crosstalk?
This is the total number pf bits in a single IPv6 address.
What is 128 bits?
This is a wireless site survey performed without visiting the physical site using blueprints and software instead.
What is predictive analysis?
This authentication protocol is commonly used for centralized "AAA".
What is RADIUS?
this protocol uses Port 143 to allow users to view and manipulate messages on a mail server without downloading them.
What is IMAP?
This small, square fiber connector is commonly referred to as the "Little connector"
What is an LC connector?
This subnet mask corresponds to a CIDR notation of /26.
What is 255.255.255.192?
This wireless frequency band offers 11 channels in the US but it suffers from high interference.
What is the 2.4 GHz band?
This social engineering tactic involves tricking a user into providing sensitive information via a fake email or website.
What is Phishing?
This is the protocol Data Unit (PDU) found at Layer 2 of the OSI model.
What is a Frame?
This specific phenomenon occurs when a signal loses strength as it travels over a long distance.
What is Attenuation?
This is the decimal value of an 8-bit octet where all bits are set to 1.
What is 255?
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 type of malware encrypts a user's data and demands payment for the decryption key
What is Ransomware?
