HP HP Certifications HPE6-A84 Questions & Answers

  • Question 51:

    You need to install a certificate on a standalone Aruba Mobility Controller (MC). The MC will need to use the certificate for the Web UI and for implementing RadSec with Aruba ClearPass Policy Manager. You have been given a certificate with these settings:

    1.

    Subject: CN=mc41.site94.example.com

    2.

    No SANs

    3.

    Issuer: CN=ca41.example.com

    4.

    EKUs: Server Authentication, Client Authentication

    What issue does this certificate have for the purposes for which the certificate is intended?

    A. It has conflicting EKUs.

    B. It is issued by a private CA.

    C. It specifies domain info in the CN field instead of the DC field.

    D. It lacks a DNS SAN.

  • Question 52:

    Which element helps to lay the foundation for solid network security forensics?

    A. Enable BPDU protection and loop protection on edqe switch ports

    B. Enabling debug-level information for network infrastructure device logs

    C. Implementing 802.1X authentication on switch ports that connect to APs

    D. Ensuring that all network devices use a correct, consistent clock

  • Question 53:

    Refer to the scenario.

    This customer is enforcing 802.1X on AOS-CX switches to Aruba ClearPass Policy Manager (CPPM). The customer wants switches to download role settings from CPPM. The "reception-domain" role must have these settings:

    -- Assigns clients to VLAN 14 on switch 1, VLAN 24 on switch 2, and so on.

    -- Filters client traffic as follows:

    -- Clients are permitted full access to 10.1.5.0/24 and the Internet

    -- Clients are denied access to 10.1.0.0/16 The switch topology is shown here:

    How should you configure the VLAN setting for the reception role?

    A. Assign a consistent name to VLAN 14, 24, or 34 on each access layer switch and reference that name in the enforcement profile VLAN settings.

    B. Configure the enforcement profile as a downloadable role, but specify only the role name and leave the VLAN undefined. Then define a 'reception' role with the correct VLAN setting on each individual access layer switch.

    C. Assign a number-based ID to the access layer switches. Then use this variable in the enforcement profile VLAN settings: %(NAS-ID]4.

    D. Create a separate enforcement profile with a different VLAN ID for each switch. Add all profiles to the profile list in the appropriate enforcement policy rule.

  • Question 54:

    Refer to the scenario.

    A hospital has an AOS10 architecture that is managed by Aruba Central. The customer has deployed a pair of Aruba 9000 Series gateways with Security licenses at each clinic. The gateways implement IDS/IPS in IDS mode.

    The Security Dashboard shows these several recent events with the same signature, as shown below:

    Which step could give you valuable context about the incident?

    A. View firewall sessions on the APs and record the threat sources' type and OS.

    B. View the user-table on APs and record the threat sources' 802.11 settings.

    C. View the RAPIDS Security Dashboard and see if the threat sources are listed as rogues.

    D. Find the Central client profile for the threat sources and note their category and family.

  • Question 55:

    Refer to the scenario.

    # Introduction to the customer

    You are helping a company add Aruba ClearPass to their network, which uses Aruba network infrastructure devices.

    The company currently has a Windows domain and Windows CA. The Window CA issues certificates to domain computers, domain users, and servers such as domain controllers. An example of a certificate issued by the Windows CA is

    shown here.

    The company is in the process of adding Microsoft Endpoint Manager (Intune) to manage its mobile clients. The customer is maintaining the on-prem AD for now and uses Azure AD Connect to sync with Azure AD.

    # Requirements for issuing certificates to mobile clients

    The company wants to use ClearPass Onboard to deploy certificates automatically to mobile clients enrolled in Intune. During this process, Onboard should communicate with Azure AD to validate the clients. High availability should also be

    provided for this scenario; in other words, clients should be able to get certificates from Subscriber 2 if Subscriber 1 is down.

    The Intune admins intend to create certificate profiles that include a UPN SAN with the UPN of the user who enrolled the device.

    # Requirements for authenticating clients

    The customer requires all types of clients to connect and authenticate on the same corporate SSID.

    The company wants CPPM to use these authentication methods:

    1.

    EAP-TLS to authenticate users on mobile clients registered in Intune

    2.

    TEAR, with EAP-TLS as the inner method to authenticate Windows domain computers and the users on them To succeed, EAP-TLS (standalone or as a TEAP method) clients must meet these requirements:

    1.

    Their certificate is valid and is not revoked, as validated by OCSP

    2.

    The client's username matches an account in AD # Requirements for assigning clients to roles After authentication, the customer wants the CPPM to assign clients to ClearPass roles based on the following rules:

    1.

    Clients with certificates issued by Onboard are assigned the "mobile-onboarded" role

    2.

    Clients that have passed TEAP Method 1 are assigned the "domain-computer" role

    3.

    Clients in the AD group "Medical" are assigned the "medical-staff" role

    4.

    Clients in the AD group "Reception" are assigned to the "reception-staff" role The customer requires CPPM to assign authenticated clients to AOS firewall roles as follows:

    1.

    Assign medical staff on mobile-onboarded clients to the "medical-mobile" firewall role

    2.

    Assign other mobile-onboarded clients to the "mobile-other" firewall role

    3.

    Assign medical staff on domain computers to the "medical-domain" firewall role

    4.

    All reception staff on domain computers to the "reception-domain" firewall role

    5.

    All domain computers with no valid user logged in to the "computer-only" firewall role

    6.

    Deny other clients access # Other requirements Communications between ClearPass servers and on-prem AD domain controllers must be encrypted. # Network topology For the network infrastructure, this customer has Aruba APs and Aruba gateways, which are managed by Central. APs use tunneled WLANs, which tunnel traffic to the gateway cluster. The customer also has AOS-CX switches that are not

    managed by Central at this point.

    # ClearPass cluster IP addressing and hostnames A customer's ClearPass cluster has these IP addresses:

    1.

    Publisher = 10.47.47.5

    2.

    Subscriber 1 = 10.47.47.6

    3.

    Subscriber 2 = 10.47.47.7

    4.

    Virtual IP with Subscriber 1 and Subscriber 2 = 10.47.47.8

    The customer's DNS server has these entries

    1.

    cp.acnsxtest.com = 10.47.47.5

    2.

    cps1.acnsxtest.com = 10.47.47.6

    3.

    cps2.acnsxtest.com = 10.47.47.7

    4.

    radius.acnsxtest.com = 10.47.47.8

    5.

    onboard.acnsxtest.com = 10.47.47.8

    The customer has now decided that it needs CPPM to assign certain mobile-onboarded devices to a "nurse-call" AOS user role. These are mobile-onboarded devices that are communicating with IP address 10.1.18.12 using port 4343.

    What are the prerequisites for fulfilling this requirement?

    A. Setting up traffic classes and role mapping rules within Central's global settings

    B. Creating server-based role assignment rules on APs that apply roles to clients based on traffic destinations

    C. Creating server-based role assignment rules on gateways that apply roles to clients based on traffic destinations

    D. Creating a tag on Central to select the proper destination connection and integrating CPPM with Device Insight

  • Question 56:

    Refer to the scenario.

    A customer has an AOS10 architecture that is managed by Aruba Central. Aruba infrastructure devices authenticate clients to an Aruba ClearPass cluster.

    In Aruba Central, you are examining network traffic flows on a wireless IoT device that is categorized as "Raspberry Pi" clients. You see SSH traffic. You then check several more wireless IoT clients and see that they are sending SSH also. You want a fast way to find a list of all the IoT clients that have used SSH.

    What step can you take?

    A. Create and apply a Central client profile tag that selects the SSH application and the clients' category.

    B. Run a search for SSH traffic and loT client IDs in Aruba ClearPass Policy Manager's (CPPM's) accounting information.

    C. Use Central's Live Events monitoring tool to detect which clients meet the desired criteria.

    D. Use Central's Gateway IDS/IPS Security Dashboard to search for SSH events and sources.

  • Question 57:

    Refer to the scenario.

    A customer is using an AOS 10 architecture with Aruba APs and Aruba gateways (two per site). Admins have implemented auto-site clustering for gateways with the default gateway mode disabled. WLANs use tunneled mode to the gateways.

    The WLAN security is WPA3-Enterprise with authentication to an Aruba ClearPass Policy Manager (CPPM) cluster VIP. RADIUS communications use RADIUS, not RadSec.

    CPPM is using the service shown in the exhibits.

    Which step can you take to improve operations during a possible gateway failover event?

    A. Chanqe the WLANs to mixed-mode forwardinq so that vou can select multiple qatewav clusters.

    B. Set up qatewav clusters manually and set VRRP IP addresses for dynamic authorization.

    C. Use auto-group clustering instead of auto-site clustering for the gateways.

    D. Enable default gateway mode for the gateway clusters.

  • Question 58:

    A customer needs you to configure Aruba ClearPass Policy Manager (CPPM) to authenticate domain users on domain computers. Domain users, domain computers, and domain controllers receive certificates from a Windows CA. CPPM should validate these certificates and verify that the users and computers have accounts in Windows AD. The customer requires encryption for all communications between CPPM and the domain controllers.

    You have imported the root certificate for the Windows CA to the ClearPass CA Trust list.

    Which usages should you add to it based on these requirements?

    A. Radec and Aruba infrastructure

    B. EAP and AD/LDAP Server

    C. EAP and Radsec

    D. LDAP and Aruba infrastructure

  • Question 59:

    Refer to the exhibit.

    A customer requires protection against ARP poisoning in VLAN 4. Below are listed all settings for VLAN 4 and the VLAN 4 associated physical interfaces on the AOS-CX access layer switch:

    What is one issue with this configuration?

    A. ARP proxy is not enabled on VLAN 4.

    B. LAG 1 is configured as trusted for ARP inspection but should be untrusted.

    C. DHCP snooping is not enabled on VLAN 4.

    D. Edge ports are not configured as untrusted for ARP inspection.

  • Question 60:

    Refer to the scenario.

    A customer has an Aruba ClearPass cluster. The customer has AOS-CX switches that implement 802.1X authentication to ClearPass Policy Manager (CPPM).

    Switches are using local port-access policies.

    The customer wants to start tunneling wired clients that pass user authentication only to an Aruba gateway cluster. The gateway cluster should assign these clients to the "eth- internet" role. The gateway should also handle assigning clients to their VLAN, which is VLAN 20.

    The plan for the enforcement policy and profiles is shown below: The gateway cluster has two gateways with these IP addresses:

    Gateway 1

    1.

    VLAN 4085 (system IP) = 10.20.4.21

    2.

    VLAN 20 (users) = 10.20.20.1

    3.

    VLAN 4094 (WAN) = 198.51.100.14

    Gateway 2

    1.

    VLAN 4085 (system IP) = 10.20.4.22

    2.

    VLAN 20 (users) = 10.20.20.2

    3.

    VLAN 4094 (WAN) = 198.51.100.12

    VRRP on VLAN 20 = 10.20.20.254

    The customer requires high availability for the tunnels between the switches and the gateway cluster. If one gateway falls, the other gateway should take over its tunnels. Also, the switch should be able to discover the gateway cluster regardless of whether one of the gateways is in the cluster.

    You are setting up the UBT zone on an AOS-CX switch.

    Which IP addresses should you define in the zone?

    A. Primary controller = 10.20.4.21; backup controller = 10.20.4.22

    B. [Primary controller = 198.51.100.14; backup controller = 10.20.4.21

    C. Primary controller = 10 20 4 21: backup controller not defined

    D. Primary controller = 10.20.20.254; backup controller, not defined
