HP HPE6-A78 Online Questions & Answers

  • Question 1:

    You have deployed a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs). One of the WLANs enforces 802.1X authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). When you test connecting the client to the WLAN, the test fails. You check ClearPass Access Tracker and cannot find a record of the authentication attempt. You ping from the MC to CPPM, and the ping is successful.

    What is a good next step for troubleshooting?

    A. Renew CPPM's RADIUS/EAP certificate.
    B. Check connectivity between CPPM and a backend directory server.
    C. Check CPPM Event Viewer.
    D. Reset the user credentials.

  • Question 2:

    You have a network with ArubaOS-Switches for which Aruba ClearPass Policy Manager (CPPM) is acting as a TACACS+ server to authenticate managers. CPPM assigns the admins a TACACS+ privilege level, either manager or operator. You are now adding ArubaOS-CX switches to the network. ClearPass admins want to use the same CPPM service and policies to authenticate managers on the new switches.

    What should you explain?

    A. This approach cannot work because the ArubaOS-CX switches do not accept standard TACACS+ privilege levels.
    B. This approach cannot work because the ArubaOS-CX switches do not support TACACS+.
    C. This approach will work, but will need to be adjusted later if you want to assign managers to the default auditors group.
    D. This approach will work to assign admins to the default "administrators" group, but not to the default "operators" group.

  • Question 3:

    What purpose does an initialization vector (IV) serve for encryption?

    A. It helps parties to negotiate the keys and algorithms used to secure data before data transmission.
    B. It makes encryption algorithms more secure by ensuring that same plaintext and key can produce different ciphertext.
    C. It enables programs to convert easily-remembered passphrases to keys of a correct length.
    D. It enables the conversion of asymmetric keys into keys that are suitable for symmetric encryption.

  • Question 4:

    A client is connected to a Mobility Controller (MC). These firewall rules apply to this client's role: ipv4 any any svc-dhcp permit ipv4 user 10.5.5.20 svc-dns permit ipv4 user 10.1.5.0 255.255.255.0 https permit ipv4 user 10.1.0.0 255.255.0.0 https deny_opt ipv4 user any any permit What correctly describes how the controller treats HTTPS packets to these two IP addresses, both of which are on the other side of the firewall:

    10.1.20.1

    10.5.5.20

    A. Both packets are denied.
    B. The first packet is permitted, and the second is denied.
    C. Both packets are permitted.
    D. The first packet is denied, and the second is permitted.

  • Question 5:

    A company has added a new user group. Users in the group try to connect to the WLAN and receive errors that the connection has no Internet access. The users cannot reach any resources. The first exhibit shows the record for one of the users who cannot connect. The second exhibit shows the role to which the ArubaOS device assigned the user's client.

    What is a likely problem?

    A. The ArubaOS device has a server derivation rule configured on it that has overridden the role sent by CPPM.
    B. The ArubaOS device does not have the correct RADIUS dictionaries installed on it to under-stand the Aruba-User-Role VSA.
    C. The role name that CPPM is sending does not match the role name configured on the Aru-baOS device.
    D. The clients rejected the server authentication on their side because they do not have the root CA for CPPM's RADIUS/EAP certificate.

  • Question 6:

    Which correctly describes one of HPE Aruba Networking ClearPass Policy Manager's (CPPM's) device profiling methods?

    A. CPPM can use Wireshark to actively probe devices, analyze their traffic patterns, and construct an endpoint profile.
    B. CPPM can use SNMP to configure Aruba switches and mobility devices to mirror client traffic to CPPM for analysis.
    C. CPPM can analyze settings such as TTL and time window size in endpoints' TCP traffic in order to fingerprint the OS.
    D. CPPM can analyze settings such as TCP/UDP ports used for HTTP, DHCP, and DNS in endpoints' traffic to fingerprint the OS.

  • Question 7:

    Which correctly describes a way to deploy certificates to end-user devices?

    A. ClearPass Onboard can help to deploy certificates to end-user devices, whether or not they are members of a Windows domain
    B. ClearPass Device Insight can automatically discover end-user devices and deploy the proper certificates to them
    C. ClearPass OnGuard can help to deploy certificates to end-user devices, whether or not they are members of a Windows domain
    D. in a Windows domain, domain group policy objects (GPOs) can automatically install computer, but not user certificates

  • Question 8:

    You have been instructed to look in an AOS Security Dashboard's client list. Your goal is to find clients that belong to the company and have connected to devices that might belong to hackers. Which client fits this description?

    A. MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Suspected Rogue
    B. MAC address: d8:50:e6:f3:6e:c5; Client Classification: Interfering; AP Classification: Neighbor
    C. MAC address: d8:50:e6:f3:6e:60; Client Classification: Interfering; AP Classification: Interfering
    D. MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Suspected Rogue

  • Question 9:

    Your Aruba Mobility Master-based solution has detected a rogue AP Among other information the ArubaOS Detected Radios page lists this Information for the AP SSID = PubllcWiFI BSSID = a8M27 12 34:56 Match method = Exact match Match type = Eth-GW-wired-Mac-Table The security team asks you to explain why this AP is classified as a rogue. What should you explain?

    A. The AP Is connected to your LAN because It is transmitting wireless traffic with your network's default gateway's MAC address as a source MAC Because it does not belong to the company, it is a rogue
    B. The ap has a BSSID mat matches authorized client MAC addresses. This indicates that the AP is spoofing the MAC address to gam unauthorized access to your company's wireless services, so It is a rogue
    C. The AP has been detected as launching a DoS attack against your company's default gateway. This qualities it as a rogue which needs to be contained with wireless association frames immediately
    D. The AP is spoofing a routers MAC address as its BSSID. This indicates mat, even though WIP cannot determine whether the AP is connected to your LAN. it is a rogue.

  • Question 10:

    What correctly describes the Pairwise Master Key (PMK) in thee specified wireless security protocol?

    A. In WPA3-Enterprise, the PMK is unique per session and derived using Simultaneous Authentication of Equals.
    B. In WPA3-Personal, the PMK is unique per session and derived using Simultaneous Authentication of Equals.
    C. In WPA3-Personal, the PMK is derived directly from the passphrase and is the same tor every session.
    D. In WPA3-Personal, the PMK is the same for each session and is communicated to clients that authenticate
