Simulare examen final 2

A technician is troubleshooting a slow WLAN and decides to use the split-the-traffic approach. Which two parameters would have to be configured to do this? (Choose two.)

• Configure the 5 GHz band for streaming multimedia and time sensitive traffic.

• Configure the security mode to WPA Personal TKIP/AES for one network and WPA2 Personal AES for the other network

• Configure the 2.4 GHz band for basic internet traffic that is not time sensitive.

• Configure the security mode to WPA Personal TKIP/AES for both networks.

• Configure a common SSID for both split networks.

A company has just switched to a new ISP. The ISP has completed and checked the connection from its site to the company. However, employees at the company are not able to access the internet. What should be done or checked?

• Verify that the static route to the server is present in the routing table.

• Check the configuration on the floating static route and adjust the AD.

• Ensure that the old default route has been removed from the company edge routers.

• Create a floating static route to that network.

Which information does a switch use to populate the MAC address table?

• the destination MAC address and the incoming port

• the destination MAC address and the outgoing port

• the source and destination MAC addresses and the incoming port

• the source and destination MAC addresses and the outgoing port

• the source MAC address and the incoming port

Refer to the exhibit. A network administrator is reviewing the configuration of switch S1. Which protocol has been implemented to group multiple physical ports into one logical link?

• PAgP

• DTP

• LACP

• STP

Which type of static route is configured with a greater administrative distance to provide a backup route to a route learned from a dynamic routing protocol?

• floating static route

• default static route

• summary static route

• standard static route

Answer explanation

Explain: There are four basic types of static routes. Floating static routes are backup routes that are placed into the routing table if a primary route is lost. A summary static route aggregates several routes into one, reducing the of the routing table. Standard static routes are manually entered routes into the routing table. Default static routes create a gateway of last resort.

What action takes place when a frame entering a switch has a unicast destination MAC address appearing in the MAC address table?

• The switch updates the refresh timer for the entry.

• The switch forwards the frame out of the specified port.

• The switch purges the entire MAC address table.

• The switch replaces the old entry and uses the more current port.

The exhibit shows two PCs called PC A and PC B, two routes called R1 and R2, and two switches. PC A has the address 172.16.1.1/24 and is connected to a switch and into an interface on R1 that has the IP address 172.16.1.254. PC B has the address 172.16.2.1/24 and is connected to a switch that is connected to another interface on R1 with the IP address 172.16.2.254. The serial interface on R1 has the address 172.16.3.1 and is connected to the serial interface on R2 that has the address 172.16.3.2/24. R2 is connected to the internet cloud. Which command will create a static route on R2 in order to reach PC B?

• R2(config)# ip route 172.16.2.1 255.255.255.0 172.16.3.1

• R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.2.254

• R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.3.1

• R2(config)# ip route 172.16.3.0 255.255.255.0 172.16.2.254

Answer explanation

Explain: The correct syntax is:
router(config)# ip route destination-network destination-mask {next-hop-ip-address | exit-interface}
If the local exit interface instead of the next-hop IP address is used then the route will be displayed as a directly connected route instead of a static route in the routing table. Because the network to be reached is 172.16.2.0 and the next-hop IP address is 172.16.3.1, the command is R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.3.1

What protocol or technology allows data to transmit over redundant switch links?

• EtherChannel

• DTP

• STP

• VTP

Refer to the exhibit. Which three hosts will receive ARP requests from host A, assuming that port Fa0/4 on both switches is configured to carry traffic for multiple VLANs? (Choose three.)

• host C

• host D

• host F

• host E

• host G

Answer explanation

Explain: ARP requests are sent out as broadcasts. That means the ARP request is sent only throughout a specific VLAN. VLAN 1 hosts will only hear ARP requests from hosts on VLAN 1. VLAN 2 hosts will only hear ARP requests from hosts on VLAN 2.

Refer to the exhibit. The network administrator configures both switches as displayed. However, host C is unable to ping host D and host E is unable to ping host F. What action should the administrator take to enable this communication?

• Associate hosts A and B with VLAN 10 instead of VLAN 1.

• Configure either trunk port in the dynamic desirable mode.

• Include a router in the topology.

• Remove the native VLAN from the trunk.

• Add the switchport nonegotiate command to the configuration of SW2.
