質問 # 33
You are configuring Policy Based Routing (PBR) for a subnet that will be used to test a new default route for your network Traffic originating from 10.2.250.0/24 should use a new default route to 10.1.1.253. Other non-default routes for this subnet should not be affected by this change.
What are two parts of the solution for these requirements? (Select two.)
- A.
- B.
- C.
- D.
- E.
正解:C、E
解説:
Explanation
Two parts of the solution for these requirements are Option C and Option E.
Option C is a part of the solution because it defines a policy-based routing action list named route_test, which specifies the next hop IP address as 10.1.1.253 for the matching traffic. This is the new default route that the user wants to use for the subnet 10.2.250.0/24. The interface null parameter indicates that the traffic will be routed to the next hop without using a specific interface1.
Option E is a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 250, which has an IP address of 10.2.250.1/24. This is the subnet that the user wants to test the new default route for. The apply policy command enables policy-based routing on the interface and associates it with the action list2.
Option A is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify the next hop IP address as 10.1.1.253, which is the new default route that the user wants to use. Instead, it specifies a next hop IP address of 10.1.1.254, which is different from the requirement.
Option B is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify any next hop IP address at all, which is necessary for policy-based routing to work. Instead, it specifies an interface null parameter without any IP address, which is invalid.
Option D is not a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 200, which has an IP address of 10.2.200.1/24. This is not the subnet that the user wants to test the new default route for, but a different subnet that should not be affected by this change.
質問 # 34
With the Aruba CX switch configuration, what is the Active Gateway feature that is used for and is unique to VSX configuration?
- A. Sixteen different VMACs are supported total as shared.
- B. Sixteen different VMACS are supported for each IPV4 and IPV6 stack simultaneously
- C. copied over the ISL link for an optimized path.
- D. Active Gateway can once MSTP instances are created for VLAN load sharing.
正解:B
解説:
Explanation
The active gateway feature is used to provide active-active layer 3 default gateway for hosts on the same subnet. It allows the switch to convert multicast streams into unicast streams over the wireless link, which improves the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. The active gateway feature is unique to VSX configuration because it eliminates the need for VRRP and avoids traffic being pushed over the ISL link, which can cause latency in the network12.
The correct answer to the question is C. Sixteen different VMACs are supported for each IPv4 and IPv6 stack simultaneously. This means that you can have a maximum of eight VMACs for IPv4, and a maximum of eight VMACs for IPv6, on a VSX pair. Only 15 VMACs are supported on 6400 switch series2.
The other options are incorrect because:
A: Sixteen different VMACs are not supported total as shared. They are supported for each IPv4 and IPv6 stack separately.
B: Active gateway can be used without MSTP instances. MSTP is a protocol that allows multiple spanning tree instances to coexist on the same switch, but it does not affect how active gateway works.
D: Active gateway does not copy traffic over the ISL link for an optimized path. It avoids using the ISL link for routed traffic and uses the local switch interface MAC instead of the virtual MAC address (VMAC) for source address1.
質問 # 35
You are working on a network where the customer has a dedicated router with redundant Internet connections Tor outbound high-importance real-time audio streams from their datacenter All of this traffic.
* originates from a single subnet
* uses a unique range of UDP ports
* is required to be routed to the dedicated router
All other traffic should route normally The SVI for the subnet containing the servers originating the traffic is located on the core routing switch in the datacenter What should be configured?
- A. Configure a BGP link between the core routing switch and the dedicated router and route filtering.
- B. Configure a dedicated VRF on the core routing switch and make the dedicated router the default route.
- C. Configure a new OSPF area including both the core routing switch and the dedicated router
- D. Configure Policy Based Routing (PBR) on the core routing switch for the VRF with the servers' SVI
正解:D
解説:
Explanation
The reason is that PBR allows you to route packets based on policies that match certain criteria, such as source or destination IP addresses, ports, protocols, etc. PBR can also be used to set metrics, next-hop addresses, or tag traffic for different routes.
質問 # 36
you need to have different routing-table requirements With Aruba CX 6300 VSF configuration.
Assuming the correct layer-2 VLAN already exists, how would you create a new SVI for a separate routing table?
- A. Create a new VLAN. and attach the routing table to it
- B. Create a new routing table, and attach VLANS to it
- C. create a new VLAN, and attach the VRF to it.
- D. Create a new SVI and use attach command.
正解:D
解説:
Explanation
The correct answer is C. Create a new SVI and use attach command.
To create a new SVI for a separate routing table, you need to use the attach command to associate the SVI with a VRF (Virtual Routing and Forwarding) instance. A VRF is a logical entity that allows multiple routing tables to coexist on the same switch. Each VRF has its own set of interfaces, routing protocols, and routes that are isolated from other VRFs.
According to the AOS-CX Virtual Switching Framework (VSF) Guide1, one of the steps to configure VRF-aware VSF is:
Configure the VRFs on each member switch and assign the SVIs to the respective VRFs using the attach command. For example:
switch(config)# vrf red
switch(config-vrf)# exit
switch(config)# interface vlan 10
switch(config-if-vlan)# ip address 10.1.1.1/24
switch(config-if-vlan)# attach vrf red
The above commands create a VRF named red and assign VLAN 10 SVI to it. The SVI has an IP address of
10.1.1.1/24.
The other options are incorrect because:
A: You cannot attach a VRF to a VLAN directly. You need to create an SVI for the VLAN and then attach the VRF to the SVI.
B: You cannot create a new routing table manually. You need to create a VRF and then use routing protocols or static routes to populate the routing table for the VRF.
D: You cannot attach a routing table to a VLAN directly. You need to create an SVI for the VLAN and then attach a VRF that has a routing table associated with it.
質問 # 37
With the Aruba CX 6200 24G switch with uplinks or 1/1/25 and 1/1/26, how do you protect client ports from forming layer-2 loops?
- A. int 1/1/1-1/1/28. loop-protect
- B. int 1/1/1-1/1/24, loop-protect
- C. int 1/1/1-1/1/28. loop-guard
- D. int 1/1/1-1/1/24. loop-guard
正解:B
解説:
Explanation
The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.
質問 # 38
When configuring UBT on a switch what will happen when a gateway role is not specified?
- A. The switch will put the client on the access VLAN
- B. The gateway will send back the deny role to the client.
- C. The switch will assign the default deny role to the client.
- D. The gateway will assign a default role to the client
正解:A
解説:
According to the Aruba Documentation Portal1, user-based tunneling (UBT) is a feature that uses GRE to tunnel ingress traffic on a switch interface to a gateway for further processing. UBT enables a switch to provide a centralized security policy, using per-user authentication and access control to ensure consistent access and permissions.
Option A: The switch will put the client on the access VLAN
This is because option A shows how UBT works on an Aruba switch. When a device connects to the network, it is authenticated using either MAC Authentication or 802.1X and triggers an enforcement policy from ClearPass, which contains an enforcement profile with a user role configuration. The user role can be assigned locally on the switch or on ClearPass as part of an enforcement profile. The user role determines the VLAN that the device belongs to and the access policies that apply to it23.
Therefore, option A is correct.

質問 # 40
With the Aruba CX switch configuration, what is the Active Gateway feature that is used for and is unique to VSX configuration?
- A. VRID is set automatically as SVI vlan id
- B. VRRP and Active Gateway can be configured on a single VLAN for interoperability
- C. VRRP and Active gateway are mutually exclusive on a VLAN
- D. VRIDs need to be non-overlapping with VRRP
正解:C
解説:
Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network. If you have enabled active gateway, VRRP is not required3. Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches. The switch views the active gateway IP as a self IP address3. Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network3. Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.

- A. MAC Caching under the user-role
- B. MAC Caching under the splash page
- C. Wireless Caching under the splash page
- D. MAC Caching under the WLAN
正解:B
解説:
MAC Caching is a feature that allows a guest user to bypass the captive portal page after the first authentication based on their MAC address1 MAC Caching can be enabled under the splash page settings in Aruba Cloud Guest2 MAC Caching can improve the user experience and reduce the network overhead by eliminating the need for repeated authentication.

You are building a configuration in Central that will be used for a standardized network design for small sites for your company, you want to use GUI configuration for gateways and Aps, while template configuration for switches. You need to align with Aruba best practices.
Which set of actions will satisfy these requirements?
- A. Create one group in Central for switches a second group for APs. and a third group for gateways Create a unique site for each location, and assign devices to the appropriate site.
- B. Create one group in Central for switches and a second group for APs and gateways. Create a unique site for each location, and assign devices to the appropriate site.
- C. Create a single group in Central. Create a unique site for each location, and assign devices to the appropriate site.
- D. Create a single group in Central. Create a unique site for each type of device, and assign devices to the appropriate site.
正解:C
解説:
Explanation
This is because option C shows how to create a single group in Central with different configuration methods defined for each device type. For example, you can create a group with the name Group1, and within this group, you can enable template-based configuration method for switches and UI-based configuration method for Instant APs and Gateways. Aruba Central identifies both these groups under a single name (Group1). If a device type in the group is marked for template-based configuration method, the group name is prefixed with TG (TG Group1). You can use Group1 as the group ID for workflows such as user management, monitoring, reports, and audit trail2.

質問 # 44
Refer to the image.
Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7
- A. The AP is configured in Mesh mode
- B. The AP is an outdoor access point.
- C. The AP is a remote access point.
- D. The AP is using a directional antenna.
正解:D
解説:
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

質問 # 45
You need to drop excessive broadcast traffic on an ingress port or an ArubaOS-CX switch. What is the best feature to use for this task?
- A. DWRR queuing
- B. Strict queuing
- C. QoS shaping
- D. Rate limiting
正解:D
解説:
According to the Aruba Documentation Portal1, the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.
This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second. Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port

質問 # 46
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements. After the configuration was complete, it was noted that a user assigned with the auditors role did not have the appropriate level of access on the switch.
The user was not allowed to perform firmware upgrades and a privilege level of 15 was not assigned to their role. Which default management role should have been assigned for the user?
- A. administrators
- B. sysadmin
- C. config
- D. sysops
正解:D
解説:
Explanation
The correct answer is B. sysops.
The sysops user role is a predefined role that allows users to perform system operations on the switch, such as backup, restore, upgrade, or reboot. The sysops user role also has access to the PUT and POST methods for REST API, which can be used to modify the switch configuration. The sysops user role has a privilege level of
15, which is the highest level of access on the switch1.
The other options are incorrect because:
A: sysadmin: The sysadmin user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The sysadmin user role does not have access to the REST API methods, and cannot perform firmware upgrades1.
C: administrators: The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires1.
D: config: The config user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The config user role does not have access to the REST API methods, and cannot perform firmware upgrades1.
質問 # 47
The administrator notices that wired guest users that have exceeded their bandwidth limit are not being disconnected Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
An administrator has performed the following configuration
What is the most likely cause of this issue?
- A. There is a mismatch between the RADIUS secret on the switch and CPPM.
- B. There is a time difference between the switch and the ClearPass Policy Manager
- C. The SSL certificate for CPPM has not been added as a trust point on the switch
- D. Change of Authorization has not been globally enabled on the switch
正解:B
解説:
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated. Reference: https://www.arubanetworks.com/techdocs/ClearPass/6.7/PolicyManager/index.htm#CPPM_UserGuide/Admin/ChangeOfAuthorization.htm https://techhub.hpe.com/eginfolib/Aruba/OS-CX_10.04/5200-6692/GUID-9B8F6E8F-9C7A-4F0D-AE7B-9D8E6C5B6A7F.html
質問 # 48
A company deployed Dynamic Segmentation with their CX switches and Gateways After performing a security audit on their network, they discovered that the tunnels built between the CX switch and the Aruba Gateway are not encrypted. The company is concerned that bad actors could try to insert spoofed messages on the Gateway to disrupt communications or obtain information about the network.
Which action must the administrator perform to address this situation?
- A. Enable Secure Mode Enhanced
- B. Enable Enhanced security
- C. Enable Enhanced PAPI security
- D. Enable GRE security
正解:C
解説:
Explanation
PAPI is the protocol that is used to establish tunnels between the CX switch and the Aruba Gateway for Dynamic Segmentation1. By default, PAPI uses a simple checksum to verify the integrity of the messages, but it does not encrypt the payload2. This could expose the network to spoofing or replay attacks by malicious actors. To address this situation, the administrator must enable Enhanced PAPI security, which uses AES-256 encryption and HMAC-SHA1 authentication to protect the tunnel traffic2. Enhanced PAPI security can be enabled on the CX switch by using the command system papi enhanced-security enable3. This will ensure that the tunnels built between the CX switch and the Aruba Gateway are encrypted and authenticated.
質問 # 49
In an ArubaOS 10 architecture using an AP and a gateway, what happens when a client attempts to join the network and the WLAN is configured with OWE?
- A. Authentication information is not exchanged
- B. No encryption is applied.
- C. The Gateway will not respond.
- D. RADIUS protocol is utilized.
正解:A
解説:
Explanation
This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE. References:
