What are two advantages of static routing over dynamic routing? (Choose two.)

• Static routing is more secure because it does not advertise over the network.

• Static routing scales well with expanding networks.

• Static routing requires very little knowledge of the network for correct implementation.

• Static routing uses fewer router resources than dynamic routing.

• Static routing is relatively easy to configure for large networks.

Which protocol can be used to monitor the network?

• AAA

• SNMP

• DHCP

• RADIUS

A network engineer is troubleshooting a newly deployed wireless network that is using the latest 802.11 standards. When users access high bandwidth services such as streaming video, the wireless network performance is poor. To improve performance the network engineer decides to configure a 5 Ghz frequency band SSID and train users to use that SSID for streaming media services. Why might this solution improve the wireless network performance for that type of service?

• The 5 GHz band has a greater range and is therefore likely to be interference-free.

• Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services.

• The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.

• The only users that can switch to the 5 GHz band will be those with the latest wireless NICs, which will reduce usage.

On which two routers would a default static route be configured? (Choose two.)

• stub router connection to the rest of the corporate or campus network

• any router where a backup route to dynamic routing is needed for reliability

• edge router connection to the ISP

• any /router running an IOS prior to 12.0

• the router that serves as the gateway of last resort

A technician is about to install and configure a wireless network at a small branch office. What is the first security measure the technician should apply immediately upon powering up the wireless router?

• Configure encryption on the wireless router and the connected wireless devices.

• Disable the wireless network SSID broadcast.

• Change the default user-name and password of the wireless router.

• Enable MAC address filtering on the wireless router.

Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227?

• Drop the packet.

• Send the packet out the Serial0/0/0 interface.

• Send the packet out the GigabitEthernet0/0 interface.

• Send the packet out the GigabitEthernet0/1 interface.

An administrator issues the ipv6 route 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::1 100 command on a router. What administrative distance is assigned to this route?

• 0

• 1

• 32

• 100

A router has used the OSPF protocol to learn a route to the 172.16.32.0/19 network. Which command will implement a backup floating static route to this network?

• ip route 172.16.0.0 255.255.240.0 S0/0/0 200

• ip route 172.16.32.0 255.255.224.0 S0/0/0 200

• ip route 172.16.0.0 255.255.224.0 S0/0/0 100

• ip route 172.16.32.0 255.255.0.0 S0/0/0 100

Refer to the exhibit. How was the host route 2001:DB8:CAFE:4::1/128 installed in the routing table?

• The route was automatically installed when an IP address was configured on an active interface.

• The route was dynamically learned from another router.

• The route was manually entered by an administrator.

• The route was dynamically created by router R1.

Refer to the exhibit. The Branch Router has an OSPF neighbor relationship with the HQ router over the 198.51.0.4/30 network. The 198.51.0.8/30 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/1/1 100 was issued on Branch and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up?

• Add the next hop neighbor address of 198.51.0.8.

• Change the administrative distance to 1.

• Change the destination network to 198.51.0.5.

• Change the administrative distance to 120.
