Subnetting & IP Routing Basics
This is a 32-bit number used in networking to define the network portion of an IP address and distinguish it from the host portion.
What is a subnet mask?
The destination IP, next hop, and interface are all part of this.
What is a routing table?
RIP is this type of routing protocol.
What is a distance vector protocol?
A VLAN is a __ grouping of devices within a network.
What is a logical?
This firewall inspects individual packets without remembering past traffic.
What is a stateless firewall?
The IP address used to send traffic when the network route is unknown.
What is the default gateway?
This type of route connects two hosts on the same network.
What is a directly connected route?
OSPF belongs to this routing protocol type
What is a link state protocol?
This allows multiple VLANs to use a single physical link.
What is trunking?
This Linux firewall tool offers a simple way to manage rules.
What is UFW (Uncomplicated Firewall)?
This command shows the routing table on a Windows machine.
What is route print?
This type of route is used when no specific route matches.
What is a default route?
This protocol calculates the best path using bandwidth, delay, and load
What is EIGRP?
The VLAN that carries untagged traffic on a trunk.
The VLAN that carries untagged traffic on a trunk.
NAT that maps multiple private IPs to one public IP using ports.
What is PAT (Port Address Translation)?
This value decreases as packets move through routers to prevent infinite loops (IPv4)
What is TTL (Time To Live)?
This field in the routing table tells the router where to send the packet next.
What is the next hop?
This protocol connects different Autonomous Systems (ASes)
What is BGP?
This setup uses subinterfaces on one router port to route between VLANs.
What is router-on-a-stick?
The rule that blocks all traffic unless explicitly allowed.
What is the default deny rule?
This kind of route is used to send packets to a single IP address only
What is a host route? (e.g., /32 in IPv4)
This is the trust level a router assigns to different routing protocols.
What is administrative distance (AD)?
The time routers take to agree on updated route information.
What is convergence?
This interface lets VLANs communicate without needing an external router.
What is an SVI (Switched Virtual Interface)?
This firewall keeps track of active sessions using a state table.
hat is a stateful firewall?
