HP HP Certifications HPE6-A42 Questions & Answers

• Question 31:

  What is the difference between WPA and WPA2 encryption?

  A. WPA encryption uses symmetric keys, and WPA2 encryption uses asymmetric keys.

  B. WPA encryption acts at Layer 3, and WPA2 encryption acts at Layer 2.

  C. WPA encryption works only with preshared key (PSK) authentication, and WPA2 encryption works with both PSK and 802.1X.

  D. WPA encryption uses TKIP by default, and WPA2 encryption uses AES by default.

  Correct Answer: D

• Question 32:

  Refer to the exhibit.

  

  A network administrator needs to specify a RADIUS server for an employee WLAN on an Aruba solution. What must the administrator enter in the Shared key field?

  A. the password defined as the preshared key for the WLAN on the Mobility Master (MM) and on authorized wireless clients

  B. the password configured in a user account with administrative rights on the RADIUS server

  C. the password configured for RADIUS clients on the RADIUS server

  D. the password defined for authorized wireless clients on the RADIUS server and also distributed to authorized wireless clients

  Correct Answer: A

• Question 33:

  A network administrator uses a wireless intrusion detection system (WIDS) to detect 802.11 association floods. At which layer do these attacks occur?

  A. Layer 1

  B. Layer 2

  C. Layer 3

  D. Layer 7

  Correct Answer: B

• Question 34:

  Which task can an Aruba Spectrum Monitor (SM) perform?

  A. Analyze wireless traffic patterns at the application level.

  B. Optimize RF through the AP channel and transmit power plans.

  C. Analyze RF signals to determine the cause of non-802.11 interference.

  D. Help to detect rogue APs in the environment.

  Correct Answer: C

• Question 35:

  A company plans to deploy a Mobility Master (MM). The MM will manage 50 Mobility Controller (MC) appliances that will control a total of 680 APs, and 10 Virtual Mobility Controllers (VMCs) that will control a total of 160 APs.

  How many MM licenses does the company require?

  A. 60

  B. 210

  C. 900

  D. 960

  Correct Answer: C

  Starting with ArubaOS 8.0.1, the MM license is required to terminate devices (controllers or APs) on Mobility Master. If the Mobility Master does not have sufficient MM licenses and an AP fails to obtain a license, that AP can get an IP address and connect to its controller, but will not broadcast an SSID.

• Question 36:

  A network administrator reduces an AP radio transmit power from 18 dBm to 15 dBm. This is a loss of 3

  dBms.

  What is the current power as a percentage of the original power?

  A. 10%

  B. 33%

  C. 50%

  D. 83%

  Correct Answer: C

• Question 37:

  Which IEEE standard provides the highest transmission rates in the 2.4GHz frequency band?

  A. 802.11a

  B. 802.11ac

  C. 802.11g

  D. 802.11n

  Correct Answer: D

• Question 38:

  What is required for a WLAN that uses WPA2-Enterprise security?

  A. a Web server to host a login portal

  B. a shared password to secure access to the WLAN

  C. RADIUS server or servers

  D. a policy to allow unauthenticated users to receive RADIUS

  Correct Answer: C

• Question 39:

  Refer to the exhibit.

  

  A company has a Mobility Master (MM)-based solution with a guest WLAN. During the captive portal

  redirection, users who access a non-HTTPS Website see the error shown in the exhibit.

  How can a network administrator prevent this error?

  A. Enable automatic CPSec certificate deployment.

  B. Replace the default Mobility Master certificate with a certificate that has the correct hostname.

  C. Replace the default server certificate for mobility controllers with a certificate signed by a trusted CA.

  D. Reconfigure the guest WLAN to use EAP methods that rely on passwords rather than certificates.

  Correct Answer: C

• Question 40:

  What is one networking setting that a network administrator can configure for roles in an Aruba solution?

  A. DHCP pool

  B. ClientMatch rules

  C. source NAT

  D. bandwidth limit

  Correct Answer: D
