S & R Final Part 9

Which three pairs of trunking modes will establish a functional trunk link between two Cisco switches? (Choose three.)

-dynamic desirable - dynamic desirable -dynamic desirable - trunk -dynamic desirable - dynamic auto

A technician is configuring a router for a small company with multiple WLANs and doesn't need the complexity of a dynamic routing protocol. What should be done or checked?

Create static routes to all internal networks and a default route to the internet.

What mitigation plan is best for thwarting a DoS attack that is creating a MAC address table overflow?

Enable port security.

What protocol or technology defines a group of routers, one of them defined as active and another one as standby?

HSRP

Refer to the exhibit. After attempting to enter the configuration that is shown in router RTA, an administrator receives an error and users on VLAN 20 report that they are unable to reach users on VLAN 30. What is causing the problem?

RTA is using the same subnet for VLAN 20 and VLAN 30.

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

A network administrator of a small advertising company is configuring WLAN security by using the WPA2 PSK method. Which credential do office users need in order to connect their laptops to the WLAN?

a user passphrase

Refer to the exhibit. What are the possible port roles for ports A, B, C, and D in this RSTP-enabled network?

alternate, designated, root, root

A company is deploying a wireless network in the distribution facility in a Boston suburb. The warehouse is quite large and it requires multiple access points to be used. Because some of the company devices still operate at 2.4GHz, the network administrator decides to deploy the 802.11g standard. Which channel assignments on the multiple access points will make sure that the wireless channels are not overlapping?

channels 1, 6, and 11

Refer to the exhibit. Which static route would an IT technician enter to create a backup route to the 172.16.1.0 network that is only used if the primary RIP learned route fails?

ip route 172.16.1.0 255.255.255.0 s0/0/0 121
