CCNA Practice Quiz: 200-125 Quiz 29

1. A switch running the STA is in the learning state. A message arrives at the switch destined for a different network segment. Which of the following best describes what the switch will do?

• It places the source address and segment in its database, and forwards the message.
• It places the source address and segment in its database, but does not forward the message.
• It does not record address or segment information. However, the message is forwarded.
• It does not record address or segment information. It does not forward the message.

2. A switch running the STA is in the listening state. A message arrives at the switch destined for a different network segment. Which of the following best describes what the switch will do?

• It does not record address or segment information. However, the message is forwarded.
• It places the source address and segment in its database, and forwards the message.
• It places the source address and segment in its database, but does not forward the message.
• It does not record address or segment information. It does not forward the message.

3. Multiple VLANs have been created on a switched internetwork. How will these VLANs affect the function of the Spanning Tree protocol?

• The creation of VLANs disables the Spanning Tree protocol.
• Each port within a VLAN belongs to a separate Spanning Tree.
• All of the VLANs belong to a single Spanning Tree.
• A separate Spanning Tree exists for each VLAN.

4. Which of the following best describes OSPF?
 

• OSPF is a classful distance vector routing protocol.
• OSPF is a classless distance vector routing protocol.
• OSPF is a classful link-state routing protocol.
• OSPF is a classless link-state routing protocol.

5. How are routing tables created by link-state routing protocols?

• The administrator initially configures each route, then they are exchanged with neighbor routers.
• Routing tables are received from neighbor routers and consolidated into the local router.
• Replacement routing tables are periodically received from the Designated Border Router.
• The SPF algorithm is applied to the topological database to create a routing table.

6. How do link-state routing protocols determine the topology of the network?

• Redundant paths are built between routers for fault tolerance.
• Each router initially exchanges LSP messages which are used to build a topological database.
• The administrator plans the hierarchical design then statically configures each routing entry.
• The Spanning Tree protocol is enabled by default to prevent looping.

7. You have a Catalyst 2950 switch with three defined VLANs: VLAN 1, VLAN 3, and VLAN 5. You connect the switch to another switch using the Fa0/1 interface, and use the switchport mode trunk command for Fa0/1.

Assuming the other switch has the default configuration, what will now pass through Fa0/1 on the switch?

• Only traffic in all default VLANs, but not for VLAN 3 or VLAN 5
• No traffic will be sent
• Only traffic in VLAN 1
• Traffic for all VLANs defined on the switch

8. You have a Layer 3 switch that is capable of interVLAN routing. What process must you complete to allow interVLAN routing on a Layer 3 switch interface?

• Configure spanning tree protocol (STP) to prevent interVLAN looping
• Implement a three-tier network design with access-layer, distribution-layer, and core-layer switches
• Configure the interface as a switch virtual interface
• Configure link-state routing, such as OSPF or EIGRP

9. If an HSRP group has a router in active state and a router in standby state, what is the result when additional routers are added to the same group?

• They are alternate HSRP routers.
• They are additional HSRP backup routers.
• They are additional HSRP member routers.
• They are HSRP fail-over routers.

10. Which effect does the standby 2 priority 110 interface configuration command have?

• The interface will participate in HSRP.
• The group priority is increased above the default.
• The priority is decreased below the default.
• The interface will participate in HSRP group 110.
