質問 # 11
Read this scenario thoroughly, and then answer each question that displays on the right side of the screen.
An architect proposes these products for a customer who wants a wireless and wired upgrade:
* Aruba 2930M switches at the access layer
* Aruba 5406R switches at the core
* Aruba AP-325s
* Aruba 7205 Mobility Controllers (MCs), deployed in a cluster
* Aruba Mobility Master (MM)
* Aruba ClearPass Cx000V
* Aruba AirWare
The architect also needs to propose a security plan for the solution. The customer has 900 employees and up to 30 guests a day. The customer wants to protect the internal perimeter of the network with authentication and simple access controls. The customer is most concerned about wireless security, but also wants to ensure that only trusted users connect on the wire. However, the customer also wants all wired traffic to be forwarded locally on access layer switches. The customer already has a third-party firewall that protects the data center.
The customer wants to use certificates to authenticate user devices, but is concerned about the complexity of deploying the solution. The architect should recommend a way to simplify. For the most part users connect company-issued laptops to the network. However, users can bring their own devices and connect them to the network. The customer does not know how many devices each user will connect, but expects about two or three per-user. DHCP logs indicate that the network supports a maximum of 2800 devices.
Refer to the provided scenario.
Which solution should the architect recommend on the 2930M switches to authenticate and control wired employee devices?
- A. 802.1X on edge ports and no tunneled node
- B. MAC-Auth on edge ports and no tunneled node
- C. Mac-Auth on edge ports and per-user tunneled node
- D. 802.1X on edge ports and per-user tunneled node
正解：B

質問 # 13
Refer to the exhibit.
The customer requires fast failover if any one link or core device fails. Which additional technology should the architect plan on the core VSF fabric to meet these criteria?
- A. BGP
- B. SmartLink
- C. VRRP
- D. OSPF graceful restart
正解：B
解説：
SmartLink is a technology that provides fast failover for access switches connected to the core VSF fabric. It detects link failures on the uplink ports and switches to the backup link within 50 ms. It also shuts down the primary link to prevent loops. SmartLink works with any routing protocol and does not require any additional configuration on the core switches. OSPF graceful restart is a feature that allows OSPF to continue forwarding traffic during a planned or unplanned restart of the routing process. However, it does not provide fast failover for link or device failures. BGP is a routing protocol that is mainly used for inter-domain routing and does not provide fast failover for link or device failures. VRRP is a protocol that provides redundancy for routers by creating a virtual router with a shared IP address. However, it does not provide fast failover for link or device failures.

For which scenario should an architect recommend Aruba Central Managed Portal (MSP)?
- A. for a service provider who needs to monitor multi-vendor environments
- B. for a service provider who needs to manage multiple customer networks
- C. for an enterprise with many branches that needs to manage services centrally
- D. for an enterprise that needs to manage data center services together with the network
正解：B
解説：
Aruba Central Managed Portal (MSP) is a cloud-based network management platform that enables service providers to centrally manage and monitor multiple tenant accounts from a single interface1. MSP mode is a multi-tenant operational mode that Aruba Central accounts can be converted into, provided these accounts have subscribed to the Aruba Central app2. MSP mode allows service providers to provision and manage tenant accounts, assign devices to tenant accounts, manage subscription keys and perform other functions such as configuring network profiles and viewing alerts3. MSP mode is suitable for the scenario where a service provider needs to manage multiple customer networks, as it simplifies tenant network operations using capabilities such as zero-touch setup, historical data reporting, PCI compliance monitoring, and troubleshooting2.

An architect needs to deliver an upgrade to an 802.11ac-based solution for a customer. The customer requires an active site survey for the new deployment. Which deliverable should the architect provide to the customer?
- A. a heat map with proposed AP locations and actual tested coverage
- B. a heat map with sources of RF interface, both 802.11 and non-802.11
- C. a heat map with existing AP locations and actual tested coverage
- D. the heat map with proposed AP locations and predictive coverage
正解：A
解説：
An active site survey is a method of measuring and validating the wireless coverage, capacity, and performance of a network in a specific environment. It involves deploying temporary APs in the proposed locations, collecting data using a survey tool, and analyzing the results to optimize the network design. A heat map is a graphical representation of the wireless signal strength, interference, noise, or other metrics in different areas of the site. A heat map with proposed AP locations and actual tested coverage is a deliverable that shows the customer the expected performance of the new 802.11ac-based solution, and allows the architect to fine-tune the AP placement, channel selection, transmit power, and antenna orientation. This deliverable also helps the customer to verify that the network meets their requirements for coverage, capacity, and quality of service. References:

質問 # 25
A customer has very high availability requirements for wireless services. The architect plans to implement clustering on several Aruba Mobility Controllers (MCs). Which benefit of this feature should the architect explain?
- A. Clustering provides wireless client load balancing and seamless failover for client sessions.
- B. Clustering provides high stability because one MC is active for all sessions and one is standby for all sessions.
- C. Clustering enables an AP with a failed MC to reconnect to a new AP after a short bootstrap.
- D. Clustering enables an AP with a failed MC to operate on its own briefly to ensure seamless connectivity.
正解：A
解説：
Clustering is a feature that allows multiple Aruba MCs to work together as a single logical entity to provide high availability, scalability, and mobility for wireless clients12. One of the main benefits of clustering is that it provides wireless client load balancing and seamless failover for client sessions. This means that:
Wireless clients are distributed evenly among the cluster members based on the available resources and the configured load balancing algorithm12. This helps to optimize the network performance and avoid congestion or bottlenecks.
Wireless clients remain connected to the same MC, called the Active AP Anchor Controller (A-AAC), throughout their roaming area within the cluster, regardless of which AP they are associated with12.
This ensures that the clients retain their IP address, subnet, and session information, and do not experience any disruption or delay in their connectivity or applications.
Wireless clients can seamlessly fail over to another MC, called the Standby AP Anchor Controller (S-AAC), in case of a failure or maintenance of their A-AAC12. The S-AAC takes over the client sessions and state information from the A-AAC without requiring any re-authentication or re-association from the clients. This minimizes the impact of the failure and provides high availability and resiliency for the wireless services.
Therefore, by explaining these benefits, the architect can demonstrate how clustering can meet the customer's high availability requirements for wireless services.
