The client devices that connect to your network include a mix of dual-band 802.11n and 802.11ac, single-band 802.11b/g/n, and some 802.11a/g/n. Your access points are configured with the same SSID on both the 2.4 and 5 GHz bands. The APs are also configured to prioritize client connectivity to 5 GHz.
How does an AP perform band steering to encourage clients to use 5 GHz?
- A . When the client sends a probe request in the 2.4 GHz band, the AP may reply with information about the 5 GHz BSS.
- B . The AP may ignore the initial probe requests or 802.11 authentication requests sent in the 2.4 GHz band by dual-band clients
- C . The AP may allow an 802.11 association with the client in the 2.4 GHz band, then send unicast channel switch announcements to the client announcing the 5 GHz channel as the new channel.
- D . After receiving probe request frames from the same client in both bands, the AP may send an association request frame to the client in the 5 GHz band.
- E . The AP may allow an 802.11 association with the client in the 2.4 GHz band, then the AP may perform a transparent client handoff by transferring the client’s MAC address to the 5 GHz radio.
You were previously onsite at XYZ’s facility to conduct a pre-deployment RF site survey. The WLAN has been deployed according to your recommendations and you are onsite again to perform, a post-deployment validation survey.
When performing this type of post-deployment RF site survey voice over Wi-Fi, what is an action that must be performed?
- A . Spectrum analysis to locate and identify RF interference sources.
- B . Frequency-band hopping analysis to detect improper RF channel implementations.
- C . Protocol analysis to discover channel use on neighboring APs.
- D . Application analysis with an active phone call on an VoWiFi handset.
Select two components that should be mandatory in every remote access wireless security policy.
- A . Encrypted VPN
- B . 802.1X/EAP
- C . Personal firewall
- D . Captive portal
- E . Wireless stun gun
What is the difference between association frames and reassociation frames?
- A . Association frames are management frames, whereas reassociation frames are control frames.
- B . Association frames are used exclusively for roaming.
- C . Reassociation frames contain the BSSID of the original AP.
- D . Only association frames are used to join a BSS.
The basic service set identifier address can be found in which topologies? (Choose all that apply.)
- A . FHSS
- B . IBSS
- C . ESS
- D . HR-DSSS
- E . BSS
