Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. What are the 3 trunk encap modes?
Isl - dot1q - negotiate (default)
Root - designated - alternate - and backup
Sends a test tone on the transmit pair. If a device is detected - CDP is used to narrow down the power class.
Globally

2. What is an end to end vlan?
Arp for local subnet - if on different subnet - will arp for dgw
A VLAN that spans the entire fabric
1-enable AAA on switch - 2-define RADIUS servers - 3-define authentication method - 4-enable 802.1x on switch - 5-conf. 802.1x ports - 6-allow hosts
Port stays up - packets from violating MACs dropped - no logging

3. What is differentiated services model QOS?
Protects STP when a physical malfunction only allows traffic in 1 direction - even though the link shows as up (cisco proprietary)
Each network device handles packets individually with no advance reservations
By an ARP access list that defines the permitted bindings
Between any type of interface as long as the interface can have an L3 address assigned

4. How do IP phones communicate with each other?
Multicasts to 224.0.0.18 (VRRP)
Once the CCM gives them the parameters - they use RTP
Distribution layer
Auto mode

5. What is the STP forward delay timer?
Data goes over native vlan - voice goes over specified VLAN - voice QOS is 802.1p
A point to point port type but the neighboring device runs traditional 802.1D STP
The time that a port spends in both listening and learning states . Default 15 seconds
1500B

6. How does L3 QOS classification happen?
They should be an unconditional Etherchannel because the WLC can't negotiate a channel.
If three are missed in a row - the neighbor is considered down and the data for that neighbor is aged
The TOS field in the header is used. 2 methods 3 bits or 6 bits
The time interval that a switch stores a DBPU before discarding it. Default 20 seconds

7. On what scope is DAI enabled?
The topology is pre-populated by downloading the topology DB into the FIB and dynamically updated. Called Cisco Express Forwarding
Every switch and router in a network must be configured with appropriate QoS features and policies
Per VLAN

Disabled - init - listen - speak - standby - active
MST attributes must be manually entereed on each switch in the region. They don' t propagate like VTP.

10. What is the LACP priority range?
If a unidirectional link is detected - the port continues normally - but the port is marked as undetermined and a syslog is generated
1-65535 (def 32768) lower priority - higher probability

Both layer 2 switching and IVR
The campus network's backbone

15. What are the 3 trunk switchport modes?
Listens to the first packet going to router and away from the router. If it can switch in both directions - it learns a shortcut path so subsequent packets can be switched without the RP
When each AP stands alone within the larger network.
Trunk - dynamic auto - dynamic desireable (default)
Missed beacons - dropped packets (max retry) - weak signal (data rate switches down) - an AP periodicallytries to find a stronger signal

16. What is the traditional MLS view of switching?
Globally or per-port
Makes use of the DHCP snooping database and static ip source binding entries. If enabled - switch will test addresses

18. How do you show HSRP status
No
2 seconds
Show standby
MAC addresses are learned from the source MAC of incoming frames. If the destination address is unknown - the frame is flooded out all except the receiving port.

19. How do you configure IP source guard for hosts that don't use DHCP?
Packets are discarded due to an ACL or policy action
802.1x with EAP over LAN (EAPOL)
By creating a static IP binding
Each network device handles packets individually with no advance reservations

20. What does UDLD do?

21. How do VRRP routers handle preemption?
Each network device handles packets individually with no advance reservations
On by default
To the virtual port-channel interface
Within a single MST region - an IST instances runs to work out a loop free topology between links where CST meets the region boundary and all switches in the region. It runs at the boundary.

22. Where is UDLD enabled?
FIB
All fiber-optic links between switches (must be enabled on both ends)
LACP port priority

26. What are the steps of RSTP convergence?
1 to 64
Limits the number if dhcp requests on a port
Each network device handles packets individually with no advance reservations
1- root bridge is elected - 2-the state of eery switch port in the STP domain must be brought from blocking state to the appropriate state

27. What address does HSRP send hello packets to?
224.0.0.2 (all routers)
Sends a voltage across the receive pairs to detect a 25k ohm resistance
Real-time Transport Protocol
Aggregation - high L3 throughput - security and policy based connectivity functions through access lists and packet filters - QoS - scalable high-speed links

Transmits keystrokes from phone and commands from CCM
A TCN BDPU is sent out of the switch's root port. The switch will continue sending TCN's every hello interval until ack'd by upstream neighbor. The root bridge will send a Config BDPU to all switches
Port stays up - but packets from violating MACs are dropped. Switch logs violating packets
63 kbps

34. What are the 2 choices for VLANs with IPT?

Gets assistance from other NSF-aware neighbors. NSF features need to be built into the routing protocols on router needing and providing assistance
Tracks of BDPUs on nondesignated ports. When those BDPUs stop coming - the port is put into loop-inconsistent state and blocks

38. What does the version number indicate when looking at CEF entries?

44. What must you be sure of if AP cells overlap?

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183

45. How is an instance defined?
The station can transmit immediately and wait for an ack
