Cisco CCIE Wireless Exam (V2.0) Sample Questions:

1. You are designing a wireless point-to-point connection between two buildings that are 5 miles (8 km) apart. Which statement is true regarding the design, considering that there is a lake between the two buildings?

A) A pair of workgroup bridges will need to be used to bridge Ethernet traffic over the air between buildings.
B) You need to be concerned with the even and odd Fresnel zones because they can result in signal cancellation or amplification.
C) Your concern should be the lake between the two buildings rather than the distance, because the water will absorb the signal.
D) You do not need to be concerned about multipath, reflection, scattering, or refraction because this is an outdoor design.
E) You need to simplify the design by putting a router on each building because wireless APs or bridges cannot carry 802.1Q traffic across the wireless link.

2. After a scheduled downtime of your 5508 WLC, you notice that only a handful of the 100 APs are rejoining the controller. All the APs are in the same subnet and use default settings. Cisco WLC debugs indicate that the APs are sending discovery and join requests. Only after shutting down all the switch ports that connect to the APs and turning five ports back on at a time can you rejoin all the APs. Why were the APs unable to rejoin the Cisco WLC, and how can you prevent this from happening in the future?

A) Having all the APs in the same VLAN created a Layer 3 broadcast storm, preventing the APs from receiving discovery and join responses from the Cisco WL You can prevent this by configuring the APs to send syslog messages to a unicast address, using the Cisco WLC CLI only.
B) Having all the APs in the same VLAN created a Layer 2 broadcast storm. You cannot prevented this from happening again.
C) Having all the APs in the same VLAN created a Layer 2 broadcast storm, preventing the APs from receiving discovery and join responses from the Cisco WLC. You can prevent this by configuring the APs to send syslog messages to a unicast address, using the Cisco WLC CLI only.
D) Having all the APs in the same VLAN created a Layer 2 broadcast storm, preventing the APs from receiving discovery and join responses from the Cisco WLC. You can prevent this by configuring the APs to send syslog messages to a multicast address, using the Cisco WLC CLI only.

3. When LAG is enabled, all ports participate in LAG by default. Which statement about LAG is true?

A) The failure of one link affects only management access, not traffic throughput.
B) If any single link fails, traffic will automatically migrate to the remaining links.
C) If only two switch ports are in the LAG group, and one switch port fails, then the other switch port will fail also.
D) If there are only two LAG connections, then all VLANs must be allowed.

4. Which of the below devices can cause unintentional RF jamming attacks against an 802.11 wireless network? (Choose two.)

A) Rogue Access Points
B) Radar
C) 900 Mhz cordless phones
D) Microwave Oven

5. Which three of these options are not valid ways to extend wireless coverage in an autonomous AP environment? (Choose three.)

A) Add additional APs in repeater mode.
B) Increase the transmitter power level.
C) Use both radios.
D) Add additional APs in access point mode.
E) Position the APs optimally.
F) Add additional APs in bridge mode.
G) Use QoS.
