100
Name four different routing protocols
RIP EIGRP OSPF BGP
100
Name the 4 Protocol Data Units (PDUs) and their respective layers.
What are bits (1), frames (2), packets (3), and segments (4)
100
This protocol stops loops in switched networks
What is Spanning-Tree Protocol?
100
What are VLANs and give reasons to use them
isolate broadcast traffic
logically group hosts according to function
increase network security
100
What are the 3 serial encapsulations available on a Cisco router?
HDLC
PPP
Frame-Relay
200
These routes are the simplest type and never change
What are Static Routes
200
This process is used to determine if a destination network is local or not
What is ANDing of the subnet mask.
200
What happens when a switch receives a frame with an unknown destination MAC address?
The frame is flooded out all ports in the same vlan except the source port.
200
What is VTP and what are the benefits?
What is VLAN Trunking Protocol
VTP simplifies switch administration by allowing switches to automatically share VLAN configuration information.
VTP helps to limit configuration errors by keeping VLAN naming consistent across the VTP domain.
200
Which serial encapsulation supports authentication?
PPP
300
These are stored in the EIGRP Topology Table
What are the Successor and Feasible Successor routes
300
Write a static default route to the last valid host IP in the subnet 192.168.10.32/27
ip route 0.0.0.0 0.0.0.0 192.168.10.62
300
Configure an IP address on an SVI for vlan 1
int vlan 1
ip address 10.2.3.4 255.255.0.0
300
What are the 3 VTP Modes
What are Server (saved in NVRAM), Client (not saved), Transparent
300
What is inverse-arp used for?
Used in Frame-Relay to dynamically map an IP address to a DLCI.
400
What is administrative distance and what are the defaults for Connected, Static, RIP, EIGRP, OSPF?
Directly Connected: 0
Static Route: 1
RIP: 120
EIGRP: 90
OSPF: 110
400

Explain the discovery and routing process if A pings B in 5 steps. (Last one is a bonus).
1. A Arps for B's MAC Address 2. A sends ICMP ping packet to B's IP and MAC address 3. B Arps for A's MAC Address 4. B sends ICMP ping reply packet to A's IP and MAC address 5. (Bonus) A displays "!!!!!" :)
400
What is the CAM?
The memory location where the MAC address table is kept for fast lookups.
400
What are the 3 trunk negotiation modes?
Static Dynamic Desirable Dynamic Auto
400
How does a Frame Relay PVC differ from a point-to-point serial connection?
A point-to-point serial connection dedicates a connection between certain source and destination router. A Frame Relay PVC allows for virtual connections between a number of source and destination routers by multiplexing the connections over the serial link.
500
Explain Distance Vector vs Link State and how their metrics are calculated
Distance-vector protocols find the best path to a remote network by judging distance via number of hops. (RIP)
Link-state uses bandwidth and delay of the line to calculate metric (EIGRP, OSPF)
500

Write an extended ACL to deny telnet traffic from PC1 to PC2, but allow all other traffic. Apply this ACL to R2's FA0/1 interface in the correct direction.
access-list 100 deny tcp host 192.168.1.10 host 192.168.2.10 eq 23 access-list 100 permit ip any any interface fa0/1 ip access-group 100 in
500
In STP, which switch becomes the Root Bridge and which port on the other switches become the root port?
Lowest Priority/MAC becomes root bridge, closest port to root bridge becomes root port.
500
Explain Router-on-a-stick and what it is used for.
It is used for InterVLAN routing. Uses a trunk link between a switch and a router that has a subinterface for each vlan on the trunk.
500
What is LMI?
Local Management Interface - Used in Frame Relay to allow the ISP's DCE to advertise the available PVCs to the customer's DTE router.
