Which of the following redudancy protocols is most suitable for a dual-homed network?
STP
RRPP
Smart Link
VRRP
Common network management features include
SNMP
Mirroring
cluster and stack
NTP
IEEE 802.10 inserts a VLAN tag (....) in the Ethernet frame header.
Before the source MAC field
After the source MAC field

After the destination MAC field
The Tag Control Information (TCl) field comprises the following elements
TPID
Priority
CFI
VLAN ID
IP voice deployment includes

Voice packet identification
Digital/analog conversion
IRF provides link and node redundancy.
True
False
The default Hold timer of GVRP is
5 centiseconds
10 centiseconds
20 centiseconds
60 centiseconds
The protocol-based VLAN feature is available only on (...) ports.
Access port
Trunk Port
Hybrid port
All types of port above
Which of the following statements are TRUE about MVRP?
MVRP provides a generic framework for devices in a switched LAN to register and de-register attribute values with one other
MVRP is a physical entity.
MVRP has four timers: Periodic, Join, Leave and LeaveAll timer.
The Multiple VLAN Registration Protocol (MVRP) is an MRP application, used to advertise and learn VLAN configuration for devices.
The MVRP registration mode of a port can be Normal, Fixed, or Forbidden. If you want to configure MVRP registration mode for a port, what the link type of the port must be?
Access
Hybrid
Trunk
Access, Hybrid or Trunk
Which of the following statements are TRUE about a trunk port?
The trunk ports of a switch can connect only to switches.
A trunk port does not change the VLAN tag of any incoming VLAN tagged frame.
Atrunk port always sends a frame out with its VLAN tag unchanged, regardless of whether the VLAN ID of the frame is the same as the PVID of the trunk port or not.
To change a trunk port into a hybrid port, you must configure the port as an access port first.
Available VLAN assignment methods include?
Port-based VLAN assignment
Protocol-based VLAN assignment
IP-based VLAN assignment
IP subnet-based VLAN assignment
Which of the following statements are TRUE about Private VLANs ?
The Private VLAN function is implemented by using hybrid ports and the shared VLAN learning mechanism.
Secondary VLANs are isolated at Layer 2, and cannot communicate with one another.
Secondary VLANs are isolated at Layer 3, and cannot communicate with one another.
The shared VLAN mechanism refers to synchronizing the MAC address entries from the secondary VLANs to the Private VLAN, with the outgoing port unchanged.
Which of the following statements are true about the relationship between a super VLAN and its sub-VLANs
Asuper VLAN has only a Layer 3 interface, and it does not contain any physical ports.
Asuper VLAN represents a set of sub-VLANs and provides Layer 3 forwarding services for these sub-VLANs.
Asub-VLAN contains only physical ports, and you cannot create a VLAN interface for a sub-VLAN.
Asuper VLAN interface enables Layer 3 communication for its sub-VLANs.
Asuper VLAN interface is UP only if any of its sub-VLAN has an UP physical port.
STP port roles include?
Root port
Designated port
Backup Port
Alternate port
In spanning tree calculation, the priority vector includes
Root ID
Root Path Cost
Forwarding Delay
Bridge ID
Port ID
A spanning tree calculation process includes
Root bridge election
Root port calculation
Designated port calculation
Alternate port calculation
STP limitations include
STP cannot remove loops.
STP cannot implement load sharing between VLANs.
STP does not provide fast convergence.
STP convergence mechanisms are not flexible.
What are the differences between RSTP and STP?
RSTP has less port states
RSTP has more port roles
They use different BPDU formats and sending modes
RSTP delivers rapid convergence upon topclogy changes
RSTP mechanisms include
Edge port mechanism
Root port rapid convergence mechanism
Designated port rapid convergence mechanism
Backup port rapid convergence mechanism
The default STP priority of switches is?
0
4096
32768
61440
Which of the following statements about the edge port are correct?
Edge ports can directly transition to the forwarding state immediately.
You can configure a port that connect two switches as an edge port.
An edge port transitions to a non-edge port when it receives a BPDU.
The edge port does not trigger any topology change when it transitions to the forwarding state
Which of the following statements about MSTP is correct?
MSTP generates multiple spanning trees based on instances.
An instance can contain one or more VLANs, and each VLAN can map only to one instance.
MSTP implement load sharing for traffic among instances.
MSTP is defined in IEEE 802.1s.
Which of the following parameters do the switches in the same MST region have?
Region name
Revision level
VLAN-to-instance mappings
Switch name
