3)
After carefully examining the network diagram above, select the correct statement regarding broadcast and collision domains:
- There is one broadcast domain and seven collision domains.

What would the result be when the following commands are executed on a Cisco Catalyst switch:
TechTarget-SW1 (config-if)# switchport port-security
TechTarget-SW1 (config-if)# switchport port-security mac-address sticky
TechTarget-SW1 (config-if)# switchport port-security mac-address sticky
- The MAC address learned dynamically is saved in the switch's running-configuration.
- The MAC address learned dynamically is saved in the switch's startup-configuration.
- The MAC address learned dynamically is saved permanently in the VLAN database.
- The statically configured MAC address is saved in the switch's running-configuration when frames from that address are received.
- The first MAC address "seen" on the specific port is allowed to access the network until the port-security timer expires.
5)
What actions does the Dynamic Host Configuration Protocol (DHCP) server take when there is an IP address conflict as shown above?
- The DHCP server will automatically resolve all conflicts after their lease is over.
- The IP addresses are removed from the DHCP pool until the conflicts are resolved.
- The IP addresses detected by gratuitous Address Resolution Protocol are removed from the pool.
- The IP addresses detected by ping are removed from the pool.
- The DHCP server needs to be restarted in order to automatically clear all conflicts.
6)
Which of the following options are used in standard access lists?
- Destination address and subnet mask
- Source address and subnet mask
- Destination address and wildcard mask
- Source address and wildcard mask
7)
Which of the following commands is used to verify the encapsulation type on a frame relay link?
- show frame-relay lmi
- show frame-relay
- show interfaces
- show frame-relay pvc
- show frame-relay map
8)
In the network diagram above, which path will packets take when travelling from host 192.168.50.126 to host 192.168.50.5?
- Packets will travel from R3 to R2 to R1.
- Packets will travel from R1 to R3 to R2.
- Packets will travel from R3 to R1 and return back to R3.
- Packets will travel from R3 to R1 and from R3 to R2 to R1.
- Packets will travel from R1 to R2 and back.
9)
One of the routers in your company has just received information about network 172.16.10.0/24 from multiple sources. Which of the below will the router consider as the most reliable source for network 172.16.10.0/24?
- An EIGRP update for network 172.16.10.0/24
- An OSPF update for network 172.16.10.0/24
- A static route to network 172.16.10.0/24
- A default route with a next hop address of 172.16.0.1
- A directly connected interface with an IP address of 172.16.10.254/24
- None of the above. The router will discard the update.

Your manager has requested you indicate which of the above ports will be Spanning Tree Protocol (STP)-designated ports:
- Switch V1, Port Fa0/0; Switch V3, Port Fa0/0; Switch V3, Port Fa0/24
- Switch V1, Port Fa0/24; Switch V2, Port Fa0/0; Switch V2, Port Fa0/24
