HP Aruba Certified Campus Access Mobility Expert Written HPE7-A07 Exam Practice Test
Question 1
You recently added ClearPass as an authentication server to an HPE Aruba Networking Central group. RADIUS authentication with Local User Roles (LUR) works fine Out the same access points cannot use Downloadable User Roles (DUR).
What should he corrected in this configuration to fa the issue with DUR?
Answer : B
For Downloadable User Roles (DUR) to function correctly with ClearPass, the Network Access Devices (NADs) need to be correctly defined in ClearPass under the 'Devices' tab. This ensures that ClearPass can identify and communicate with the NADs to deliver the appropriate user roles. If the NADs are not correctly defined, ClearPass will not be able to provide the DURs to the access points for enforcement. This is a common configuration step that is required to integrate ClearPass with network devices for advanced role-based access control.
Question 2
Your customer asked for help to apply an ACL for wireless guest users with the following criteria:
* Wi-Fi guests are on VLAN 555
* allow internet access
* only allow access to public DNS servers
* deny access to all internal networks except for any DHCP server
These session ACLs are already present in the CLI of the mobility gateway group:
You have access to the CLl. Which user role meets all the criteria?
A)
B)
C)
D)
Answer : A
Based on the criteria provided for wireless guest users, the correct user role configuration must allow internet access, only allow access to public DNS servers, deny access to all internal networks except for any DHCP server, and place the Wi-Fi guests on VLAN 555. The ACLs must permit services necessary for basic internet access (such as DNS and DHCP) and block access to internal networks.
Option A satisfies these criteria with the following configurations:
user-role 'WiFi-guest': This defines the role for Wi-Fi guests.
access-list session dhcp-acl: This applies the access list that likely permits DHCP, which is necessary for guests to obtain an IP address.
access-list session dns-acl: This applies the DNS access list, which likely restricts guests to using public DNS servers.
access-list session internal-networks: This applies the internal networks access list, which denies access to internal networks.
vlan 555: This sets the VLAN for Wi-Fi guests to 555.
Options B, C, and D are incorrect because they include access-list session allowall which would permit all traffic, contradicting the requirement to deny access to all internal networks.
Question 3
An OSPF router has learned a pain 10 an external network by Doth an E1 and an E2 advertisement Both routes have the same path cost Which path will the router prefer?
Answer : A
In OSPF, when a router learns about an external network through both E1 and E2 advertisements, and if both have the same path cost, the router will prefer the E1 path. This is because E1 routes consider both the external cost to reach the external network and the internal cost to reach the ASBR, providing a more comprehensive metric. E2 routes only consider the external cost and ignore the internal cost to the ASBR, which could potentially lead to suboptimal routing. Therefore, the router will choose the E1 path due to its more accurate representation of the total path cost.
Question 4
Refer to the exhibit.
Which statement is true?
Answer : C
The exhibit shows a series of 802.1X authentication steps with multiple 'Deauthentication' frames, which indicate that the client is not successfully completing the authentication process. Since the frames show repeated attempts at authentication followed by deauthentication, this suggests that the client is failing the 802.1X authentication process, which is required for network access in a WPA2/WPA3-Enterprise security environment.
Question 5
Exhibit.
Which user role will be assigned when a voice client tries to connect for the first time, but the RADIUS server is unavailable?
Answer : C
In the provided configuration for interface 1/1/7, there are roles specified for different scenarios concerning authentication. When a voice client attempts to connect and the RADIUS server is unreachable, the role that is assigned is the one specified as the 'critical-voice-role'. In this case, the 'CRITICAL_VOICE' role is configured to be assigned under such circumstances, ensuring that voice clients receive appropriate network access permissions even when the RADIUS server is not available to authenticate them.
Question 6
The ACME company has an AOS-CX 6200 switch stack with an uplink oversubscription ratio of 9.6:1. They are considering adding two more nodes to the stack without adding any additional uplinks due to cabling constraints One of their architects has expressed concerns that their critical UDP traffic from both wired and bridged AP clients will encounter packet drops. They have already applied the following configuration:
Which strategy will complement this solution to achieve their objective?
Answer : D
Given that the ACME company's concern is about UDP traffic potentially encountering packet drops due to uplink oversubscription, they need a strategy that prioritizes critical UDP traffic to minimize loss.
Option D, edge mark critical UDP traffic with AF42, is the correct answer. Assured Forwarding (AF) classes provide a way to assign different levels of delivery assurance for IP packets. AF42 is typically used for traffic that requires low latency and low loss, such as voice and video, which often use UDP. Marking critical UDP traffic with AF42 will help ensure that this traffic is treated with higher priority over the network.
Option A (edge mark lower priority TCP traffic with AF12) and Option C (edge mark lower priority TCP traffic with AF11) suggest marking lower priority TCP traffic, which does not directly address the concern for critical UDP traffic.
Option B (edge mark critical UDP Traffic with CS5) suggests using Class Selector 5 for critical UDP traffic, which is also a valid approach but does not match the existing configuration that is focused on Assured Forwarding (AF) classes.
Question 7
A customer is evaluating device profiles on a CX 6300 switch. The test device has the following attribute:
* MAC address=81:cd:93:13:ab:31
The test device needs to be assigned the "lot-prod'' role, in addition the "lot-default" role must be applied for any other device connected lo interface 1/1/1. This is a lab environment with no configuration of any external authentication server for the test.
Given the configuration example, what is required to meet this testing requirement?
Answer : B
The fallback role is used as a default role in the absence of a specified role or when an authentication server is not available. Given the scenario, where the test device with MAC address 81:cd:93:13:ab:31 needs to be assigned to 'iot-prod' and other devices to 'iot-default', and considering there is no external authentication server configured for the test, the appropriate action would be to set a global fallback role that applies to all devices connecting to the network. This ensures that any device that does not match the specific device profile will inherit the 'iot-default' role. Since the configuration for a specific MAC address (81:cd:93:xx:xx:xx) to associate with the 'iot-prod' role is already in place, setting the fallback role globally accommodates the requirement for other devices.
