HPE7-A01 exam questions

1. Question 1

   Single answer

   Which feature supported by SNMPv3 provides an advantage over SNMPv2c?

   • A

     Transport mapping

   • B

     Community strings

   • C

     GetBulk

   • D

     Encryption

   Reveal answer

   Correct answer

   • D

     Encryption

   Explanation

   Encryption is a feature supported by SNMPv3 that provides an advantage over SNMPv2c. Encryption protects the confidentiality and integrity of SNMP messages by encrypting them with a secret key. SNMPv2c does not support encryption and relies on community strings for authentication and authorization, which are transmitted in clear text and can be easily intercepted or spoofed. Transport mapping, community strings, and GetBulk are features that are common to both SNMPv2c and SNMPv3. https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/snmp/snmp.htm https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/snmp/snmpv3.htm

2. Question 2

   Multiple answer

   Two AOS-CX switches are configured with VSX at the the Access-Aggregation layer where servers attach to them An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.

   What is correct about access from the servers to the Core? (Select two.)

   

   • A

     Server 1 can access the core layer via the keepalrve link

   • B

     Server 2 can access the core layer via the keepalive link

   • C

     Server 2 cannot access the core layer.

   • D

     Server 1 can access the core layer via both uplinks

   • E

     Server 1 and Server 2 can communicate with each other via the core layer

   • F

     Server 1 can access the core layer on only one uplink

   Reveal answer

   Correct answer

   • D

     Server 1 can access the core layer via both uplinks

   • E

     Server 1 and Server 2 can communicate with each other via the core layer

   Explanation

   These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question. https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-

5. Question 4

   Ordering

   What is the order of operations tor Key Management service for a wireless client roaming from AP1 to AP2?

   

   • A

     Cache the client's information

   • B

     Client Associates and authenticates to AP1

   • C

     Generate Parawise Master Key keys for AP1's neighbors

   • D

     Get AP1 neighbour AP list

   • E

     Share Parawise Master Key along with VLAN and User Role to target APs

   Reveal answer

   Correct order

   1. 1 B

      Client Associates and authenticates to AP1

   2. 2 A

      Cache the client's information

   3. 3 C

      Generate Parawise Master Key keys for AP1's neighbors

   4. 4 D

      Get AP1 neighbour AP list

   5. 5 E

      Share Parawise Master Key along with VLAN and User Role to target APs

6. Question 5

   Single answer

   Your manufacturing client is having installers deploy seventy headless scanners and fifty IP cameras in their warehouse These new devices do not support 802 1X authentication.

   How can HPE Aruba reduce the IT administration overhead associated with this deployment while maintaining a secure environment using MPSK?

   • A

     Have the installers generate keys with ClearPass Self Service Registration.

   • B

     Have the MPSK gateway derive the unique pre-shared keys based on the MAC OUI.

   • C

     Use MPSK Local to automatically provide unique pre-shared keys for devices.

   • D

     MPSK Local will allow the cameras to share a key and the scanners to share a different key

   Reveal answer

   Correct answer

   • C

     Use MPSK Local to automatically provide unique pre-shared keys for devices.

   Explanation

   MPSK Local is a feature that can reduce the IT administration overhead associated with deploying devices that do not support 802.1X authentication while maintaining a secure environment. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require manual intervention by the installers or the MPSK gateway, or they do not provide unique pre-shared keys for devices. https://www.arubanetworks.com/techdocs/AOS-CX_10_08/UG/bk01-ch05.html https://www.arubanetworks.com/techdocs/AOS-CX_10_08/UG/bk01-ch06.html
