HPE7-A07 Aruba Certified Campus Access Mobility Expert Written Exam Practice Test
Question 1
Exhibit.
Which wireless connection phase has Just been completed?
Answer : D
The wireless connection phase that has just been completed is L2 authentication and encryption. This phase includes processes such as the Extensible Authentication Protocol (EAP) exchange, RADIUS requests and responses, and the 4-way handshake which is characteristic of WPA2-AES encryption.
Question 2
A BGP routing table contains multiple routes to the same destination prefix.
Referring to the table below which route would be marked with a ">" symbol?
Answer : E
In BGP, the route marked with a '>' symbol is the best route that is chosen based on BGP attributes in the following order: highest weight (Cisco-specific), highest local preference, originated by BGP running on the local router, shortest AS path, lowest origin type, lowest MED, eBGP over iBGP, closest IGP neighbor, and lowest BGP router ID. Based on the table provided, Option E would be marked with a '>' symbol as it has the highest local preference of 100 which is a decisive factor in the BGP best path selection process.
Question 3
Which option shows the correct Banawidth Control for 1024 kbps down and 2048 Kops up for the SSID?
A)
B)
C)
D)
Answer : D
The correct Bandwidth Control settings for 1024 Kbps down and 2048 Kbps up for the SSID are shown in Option D. In Option D, the downstream is set at 1024 Kbps and the upstream at 2048 Kbps, both configured per user, which matches the requested configuration. This setup ensures that each user has a guaranteed bandwidth allocation of the specified rates when connected to the SSID, providing a controlled and predictable user experience.
Question 4
A customer is evaluating device profiles on a CX 6300 switch. The test device has the following attributes:
* MAC address = 81:cd:93:13:ab:31
* LLDP sys-desc = iotcontroller
The test device is being assigned to the ''lot-dev'' role However, the customer requires the "lot-prod'' role be applied.
Given the configuration, what is causing the "iot-dev" role to be applied to the device'?
Answer : D
In device profile configuration, the device role is often determined by matching attributes such as MAC address, LLDP system description, and CDP information against defined conditions. The test device is being assigned the 'iot-dev' role because its LLDP system description matches the 'iot-lldp' group configuration that is associated with the 'iot-dev' role.
Question 5
Exhibit.
After configuring VRRP between sw-1 and SW-2. you notice that both switches are showing as active. What could be the reason for this issue?
Answer : C
In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.
Question 6
Exhibit.
A university runs its own TV station in the city The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications in order to improve the bandwidth consumption. PlM sparse Mode and IGMP snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way While troubleshooting the network administrator saves the packet captures shown in the exhibit and concludes that all users even those not joining the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?
Answer : A
Dynamic Multicast Optimization (DMO) and Multicast Transmission Optimization are features that can help address issues with multicast traffic in wireless environments. DMO optimizes the way multicast traffic is transmitted over the air by converting multicast streams into unicast streams to the clients that need them. This reduces unnecessary traffic for clients that have not subscribed to the multicast group and can improve overall network performance. Multicast Transmission Optimization adjusts the transmission rate of multicast frames to ensure they are sent at optimal speeds, addressing the issue of multicast flow being received at slow speeds by all users.
Question 7
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.
