Question #1 - Topic 1

Click the Exhibit button and view the three exhibits.




A customer has determined that an access point (AP) HP A-WA2620E-AGN is not
communicating correctly with an A3000-10G-PoE+ wireless switch active controller. The
customer uses the port mirroring feature to examine all the packets transmitted and
received by the AP. The customer Ethernet analyzer is connected to gigabit port 1/0/2 and
is mirroring gigabit port 1/0/3. The HP A-WA2620E-AGN AP is receiving power from an
external POE source. If the AP sends a single broadcast DHCP request packet, how many
instances of the packet will the customer Ethernet trace capture and If the AP sends a
single broadcast DHCP request packet, how many instances of the packet will the
customer? Ethernet trace capture and display?

A. 0

B. 1

C. 2

D. 3

Question #2 - Topic 1

Click the Exhibit button and view the four exhibits.




You install your access point (AP) in the network shown in Exhibit 1 and configure the AP
to support an ESSID called dot1xaccess. The ESSID enforces 802.1X authentication to a
Windows Internet Authentication Service (IAS) server, for which the configuration is
displayed in Exhibits 2 and 3. A wireless user uses the test1 user name and password to
associate to the dot1xaccess ESSID. The user is granted access as shown in Exhibit 4.
You expected the user to receive an IP address in the 192.168.0.0/24 subnet (VLAN 1).
Instead, the user received an IP address in the 192.168.1.0/24 subnet (VLAN 2). Assuming
that the wireless switch controller is configured properly, what is the reason for this
occurrence?

A. The password entered by the wireless client during 802.1x authentication was not the correct password for the test1 user account.

B. The IAS server was not connected to a port assigned to desired VLAN (VLAN 1, subnet 192.168.0.0/24).

C. The wireless user must use credentials associated with a different group for 802.1X authentication to assign the user to the desired VLAN.

D. The IAS remote access policy "hpdot1xVLAN1" was not placed in first position in the IAS Server remote access policy list.

A customer has deployed an 802.1X SSID as shown in the exhibits. The customer is trying
to connect to SSID dot1_x., but the windows machine will not connect to the SSID. What is
one reason why this is happening?

A. The wireless client has not selected the correct network authentication method.

B. The wireless client has not correctly installed a user certificate on the pc.

C. The wireless client has selected the wrong security type for encryption.

D. The active controller is configured for EAP-TLS (Smart-Card).

Question #4 - Topic 1

A customer reports the performance of their HP A-WA2620E access point (AP) is
inadequate. While investigating the report, you determine that the AP is functioning in
MIMO 3x2 mode instead of MIMO 3x3 as desired. What is one possible cause of this
problem?

A. The AP is powered using 802.3af PoE.

B. The AP is configured to use a 40Mhz channel bandwidth.

C. The AP is not implementing the local switching feature.

D. The AP is powered using 802.3at PoE.

A university media course uses an auditorium that seats 400 students. Wireless access
points (APs) are installed to provide access to the school's video servers. Students running
802.11n clients are not seeing optimal bandwidth connection data rates. Based on the
exhibits, what is a solution to optimize 802.11n data rates?

A. Disable High Throughput (HT mode) on all radios.

B. Disable RTS/CTS capability on non-802.11n client NICs.

C. Configure Band Steering mode on radio 1 on all APs and radio 2 on AP3 and AP5.

D. Configure Greenfield mode on radio1 on all APs and radio 2 on AP3 and AP5.

Question #6 - Topic 1

Click the Task button.
A customer wants to verify that wireless traffic is being tunneled back from the access point
(AP) to the active controller. The customer takes a trace of the AP uplink port. A wireless
user (PC1) pings the Layer 3 switch and gets a reply. Based on the exhibits provided,
identify the correct IP address of the wireless user, the active controller, the Layer 3 switch,
and the AP.

Question #7 - Topic 1

Assume all access points (APs) are correctly configured. The HP A-WA2620E-AGN AP is
receiving power from an external PoE source. A wireless user associates to ESSID
HP_Openaccess. Based on the exhibits, what is the expected behavior of the wireless
user's traffic? (Select two.)

A. The wireless user is assigned to VLAN 1 but cannot communicate because the AP's uplink port is assigned to VLAN 2 only.

B. The wireless user's traffic is encrypted with Temporal Key Integrity Protocol (TKIP).

C. The wireless user is assigned to VLAN 2 because the AP's uplink port configuration takes precedence over other configurations.

D. The wireless user's traffic is encrypted with Advanced Encryption Standard (AES).

E. The wireless user is assigned to VLAN 1 and all traffic sent to the HP A-WA2620E-AGN AP is tunneled back to the A3000-10G-PoE+ wireless switch active controller.

Question #8 - Topic 1

A customer defined an essid "ESSID2". This should place associated wireless users in
VLAN 2 and also locally forward the traffic from the AP uplink. However, when the wireless
users associate to "ESSID2", they do not successfully receive an IP address in subnet
192.168.1.0/24 (VLAN 2). Based on the exhibits, what could explain this behavior?

A. The active controller port gig 1/0/1 is not part of VLAN 2.

B. The switch side port gig 1/0/11 is not part of VLAN 2.

C. The file apcfg.txt is not configured correctly.

D. The file apcfg.txt is not created on the active controller.

Question #9 - Topic 1

Which action does RF Manager take to quarantine a client?

A. It instructs the client's access point to place the client's traffic in a quarantine VLAN.

B. It instructs a sensor to send a forced disassociation message to the client's access point (AP) so that the AP forces the client to disconnect.

C. It instructs a sensor to send frames to interfere with the frames sent by the quarantined client.

D. It adds the client's MAC address to the access point's MAC lockout list, thereby blocking the client's traffic.

Question #10 - Topic 1

You deploy a wireless system in a hospital. The customer has very critical devices that
require as much redundancy installed as possible. You install two active controllers in a
1+1 hot backup configuration. While testing, you connect a client to AP1 and confirm that
you have all the network connectivity needed. However, when you power down the Master
active controller your client loses all network connectivity. What is a possible cause of this
problem?

A. The Master controller was not configured correctly for hot backup mode.

B. The AP was not configured correctly on the backup controller.

C. The Master controller never established a hot backup connection to the backup controller.

D. The Master controller and backup controller are on the same subnet.
