OSI Model & Protocols
This protocol operates on Port 443 and provides encrypted communication for web traffic.
What is HTTPS?
This specific copper cable category can support 10Gbps speeds up to 100 meters.
What is Cat 6a?
This is the practice of limiting an interface's access to only specific, authorized MAC addresses.
This latest WPA standard introduced individualized data encryption and the DragonFly Key Exchange.
What is WPA3?
This device allows multiple VLANs to be managed and routed on a single switch without an external router.
What is a Layer 3 switch?
This protocol uses Port 22 to provide a secure, encrypted terminal connection to a remote device.
What is SSH?
This hardware device is used to connect multiple network segments and can be "managed" or "unmanaged."
What is a switch?
This social engineering tactic involves tricking a user into providing sensitive information via a fake email or website.
What is phishing?
This feature allows a wireless client to stay connected while moving from one Access point to another.
What is roaming?
This logical grouping of network users allows them to be separated as if they were on different physical switches.
What is a VLAN?
This is the Protocol Data Unit (PDU) found at Layer 2 of the OSI model.
What is a Frame?
This type of interference occurs when electrical signals from one wire pair leak into an adjacent pair.
What is crosstalk?
This security feature on a switch prevents unauthorized DHCP servers from handing out IP addresses?
What is DHCP snooping?
This is the name given to the unique ID or "name" of a wireless network.
What is the SSID?
this value in an IP is decremented by each router to prevent packets from looping forever.
What is TTL (Time To Live)?
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 security device inspects incoming and outgoing traffic to block unauthorized access based on a set of rules.
What is a firewall?
This wireless frequency band offers 11 channels in the US (3 non-overlapping) but suffers from high interferece.
What is the 2.4 GHz band?
This port mirroring feature on a switch allows you to copy all traffic from one port to another for analysis.
What is SPAN?
This PDU is associated with Layer 4 (Transport) when using the TCP protocol.
What is a Segment?
This specific phenomenon occurs when a signal loses strength as it travels over long distance.
What is Attenuation?
This VPN protocol uses a combination of AH and ESP to provide data integrity and confidentiality.
What is IPsec?
This technology allows a wireless access point to use multiply antennas to transmit and receive data simultneously.
What is MIMO?
This protocol is used by network devices to send error messages and operational information, such as "Destination Unreachable."
What is ICMP?
