You are testing a VoWLAN deployment, and your communication measurements show a certain amount of lost packets. What would be an acceptable packet error rate value to still provide acceptable call quality?
B. No more than 1% PER max should be acceptable
C. No more than 4% PER max should be acceptable
D. No more than 8% PER max should be acceptable
E. No more than 12% PER max should be acceptable
You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise floor was approximately -94 dBm on this floor of the building. The phone's documentation does not specify a recommended RSSI or SNR value for best performance. Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas you are monitoring and where VoWiFi service is desired?
B. 72 dBm
C. 67 dBm
D. 62 dBm
E. 58 dBm
What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags? (Choose 2)
shorter transmit range of passive tags as compared to active tags.
B. Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized
with the AP for proper location of the tagged asset.
C. With passive tags, AP transmit gain should be increased to supply extra power for near-field coupling
or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.
D. Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the
tag interrogator to communicate tag information to the infrastructure's location tracking server/database.
E. Active tags transmit directly to the APs and may not require 802.11 authentication and association to
pass data traffic to the RTLS engine.
F. When tracking assets with passive RFID tags, some APs should be moved, or additional APs be added,
to provide more accurate triangulation and location services.
At a university, the WLAN has been successfully deployed for ubiquitous access for faculty, students, and guests. Many student computer labs are available throughout the campus with wired network connectivity, but there are also a few smaller lab areas and workstations where Ethernet cabling is not available. For student wireless use, the students must authenticate against RADIUS/Active Directory using PEAP. Also, the network administrators at this university would like administrative access to these workstations when they are not in use by students so that the administrators can manage group policies, update OS patches, and perform other routine software maintenance. What deployment options are available and recommended for both student use and remote administration of these workstations? (Choose 2)
to access network services required by network administrators in this scenario.
B. Machine authentication accounts should be enabled to provide persistent machine network connectivity
when student users are not associated.
C. The WLAN infrastructure vendor is responsible for providing proprietary client connectivity options to
facilitate device connectivity without user interaction.
D. These workstations should be Ethernet-connected to a wireless client bridge, which will maintain network
connectivity independent of student connectivity status.
E. These stations should be deployed with dual WLAN adapters. One adapter would be used for consistent
network connectivity for administrative purposes and the second adapter should be used for student access.
What are some advantages of designing guest access as it is shown in the exhibit?
corporate users and guests
B. Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN
C. The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller
D. Enhances performance of web proxy servers in the DMZ for guest Internet traffic
E. Allows simple and secure guest collaboration (file/print sharing) with corporate users
ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped VoWiFi calls and leading to data connectivity and throughput problems.
What steps should ABC Manufacturing take to most effectively remedy this problem?
B. Solution 2
C. Solution 3
D. Solution 4
In this question, you will compare the mobility processes of a network that supports WPA2-Personal and WPA2-Enterprise. Assume the use of a 15-character ASCII passphrase for WPA2-Personal and EAP-TTLS/MSCHAPv2 with WPA2-Enterprise. Also, assume that proprietary roaming protocols are not supported. When a device transitions from one BSS to another within the same ESS, what steps must be performed in the WPA2-Enterprise transition that are not performed in the WPA2-Personal transition? (Choose 2)
B. 802.11 Reassociation
C. 802.1X authentication
D. 4-Way Handshake
E. Transfer of PMK from AAA server to authenticator
F. Conversion of passphrase to PMK
You captured the wireless frame shown in the exhibit during a post-deployment verification site survey. What can you tell the customer about this network?
value should not be set to 0.
B. This is a voice control packet, and the configuration looks normal, as voice control may or may not have
a DSCP tag.
C. This is a video stream packet, and the configuration looks normal, as DSCP is always set to 0 when
802.11e QoS is specified at Layer 2.
D. This is a voice RTP packet, and its marking was downgraded from Voice to Video which is a sign of
During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame displayed in the exhibit from the location where problems are reported. This frame is typical of those that were captured by the analyzer. What does this frame reveal about the RF network in this area?
B. Contention Free is in place in this network, which may starve some non-QoS stations from access
C. Multipath or excessive collisions seem to be an issue in this area
D. The AP seems to be too far to provide enough coverage to this area
E. Stations are using null data frames as protection mechanisms to reserve the medium
F. The station that sent this frame is causing a DoS attack by using extended Duration values
Excessive uplink RTP frame retransmissions can result in ____________. (Choose 3)
B. Lowering of the data transmission rate by the transmitting station
C. MOS scores in excess of 5
D. Head-of-Line blocking at the receiver
E. Shortened battery life of a transmitting station
F. Increased jitter in a VoWiFi connection
A. There should be 0% error in a VoWLAN type of deployment
A. 75 dBm
