Switching
This switching method checks the first 64 bytes of a frame before forwarding.
Fragment-Free
The default VLAN on Cisco switches.
VLAN 1
This routing protocol uses hop count as its metric.
RIP
What is the CIDR notation for 255.255.255.0?
/24
This Layer 3 protocol provides logical addressing and fragmentation.
IP (Internet Protocol)
What protocol is used to prevent loops in a Layer 2 network?
What is the protocol number?
Spanning Tree Protocol (STP)
802.1D
What is the IEEE standard for VLAN tagging?
802.1Q
What metric is OSPF based on?
bandwidth
What number of subnets is created with a /28 mask in a Class C network?
16
OSPF and EIGRP use this type of packet to discover and maintain neighbor relationships.
Hello packets
The type of memory where a switch stores its "running-config."
RAM
Which VLAN that isolates unused switch ports for security?
Dead VLAN
Why is EIGRP known as "balanced hybrid"?
It combines link-state protocol and distance vector protocol advantages.
What is the first usable address in the subnet 192.168.1.64/26?
192.168.1.65
This protocol sends "Destination Unreachable" and is used by the ping command.
ICMP (Internet Control Message Protocol)
The unique identifier a switch uses to forward frames.
MAC address
The type of port that carries traffic for multiple VLANs.
Trunk port
BGP is an example of what type of routing protocol?
Distance Vector
_______ is the term for borrowing bits from the host portion of an IP address.
Subnetting
What protocol resolves Layer 3 IP addresses to Layer 2 MAC addresses using broadcasts?
ARP (Address Resolution Protocol)
When the destination hardware address is not listed in the switch's MAC address, the frame is ______ out of all the active ports, except for the interface where the frame is recieved.
flooded / broadcast
What protocol is used by Cisco devices to share VLAN information?
VTP
What table stores only the best paths to networks?
What table tracks adjacent routers?
What table contains all possible routes for a protocol like EIGRP?
Routing Table
Neighbor Table
Topology Table
What technique allows different subnet sizes in one network?
VLSM (Variable Length Subnet Mask)
What exterior gateway protocol uses paths to route between autonomous systems?
What link-state protocol uses areas and calculates cost based on interface bandwidth?
What distance-vector protocol has a max hop count of 15 and sends full routing table updates?
What Cisco-proprietary hybrid protocol uses DUAL algorithm and maintains neighbor/topology tables?
BGP (Border Gateway Protocol)
OSPF (Open Shortest Path First)
RIP (Routing Information Protocol)
EIGRP (Enhanced Interior Gateway Routing Protocol)
