質問 # 69
In AOS 10. which session-based ACL below will only allow ping from any wired station to wireless clients but will not allow ping from wireless clients to wired stations"? The wired host ingress traffic arrives on a trusted port.
- A. ip access-list session pingFromWired any user any permit
- B. ip access-list session pingFromWired user any svc-icmp deny any any svc-icmp permit
- C. ip access-list session pingFromWired any any svc-icmp deny any user svc-icmp permit
- D. ip access-list session pingFromWired any any svc-icmp permit user any svc-icmp deny
正解：C
解説：
Explanation
A session-based ACL is applied to traffic entering or leaving a port or VLAN based on the direction of the session initiation. To allow ping from any wired station to wireless clients but not vice versa, a session-based ACL should be used to deny icmp echo traffic from any source to any destination, and then permit icmp echo-reply traffic from any source to user destination. The user role represents wireless clients in AOS 10.

質問 # 70
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 issue?
- A. The AP is using a directional antenna.
- B. The AP is an outdoor access point.
- C. The AP is configured in Mesh mode
- D. The AP is a remote access point.
正解：A
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 # 71
A customer just upgraded aggregation layer switches and noticed traffic dropping for 120 seconds after the aggregation layer came online again.
What is the best way to avoid having this traffic dropped given the topology below?
- A. Configure the linkup delay timer to 240 seconds to double the amount of lime for the initial phase to sync
- B. Configure the linkup delay timer to include LAGs 101 and 102, which will allow time for routing adjacencies lo form and to learn upstream routes
- C. Configure the linkup delay timer to 120 seconds, which will allow the right amount of time for the initial phase to sync
- D. Configure the linkup delay timer to exclude LAGS 101 and 102, which will allow time for routing adjacencies to form and to learn upstream routes
正解：B
解説：
The reason is that the linkup delay timer is a feature that delays bringing downstream VSX links up, following a VSX device reboot or an ISL flap. The linkup delay timer has two phases: initial synchronization phase and link-up delay phase.
The initial synchronization phase is the download phase where the rebooted node learns all the LACP+MAC+ARP+STP database entries from its VSX peer through ISLP. The initial synchronization timer, which is not configurable, is the required time to download the database information from the peer.
The link-up delay phase is the duration for installing the downloaded entries to the ASIC, establishing router adjacencies with core nodes and learning upstream routes. The link-up delay timer default value is
180 seconds. Depending on the network size, ARP/routing tables size, you might be required to set the timer to a higher value (maximum 600 seconds).
When both VSX devices reboot, the link-up delay timer is not used.
Therefore, by configuring the linkup delay timer to include LAGs 101 and 102, which are part of the same VSX device as LAG 201, you can ensure that both devices have enough time to synchronize their databases and form routing adjacencies before bringing down their downstream links.

質問 # 73
A customer has a large number of food-producing machines
* All machines are connected via Aruba CX6200 switches in VLANs 100.110. and 120
* Several external technicians are maintaining this special equipment
What are the correct commands to ensure that no rogue DHCP server will impact the network?
- A.
- B.
- C.
- D.
正解：C
解説：
Explanation
Option A shows the correct commands to ensure that no rogue DHCP server will impact the network. The commands include the following steps:
* Enable DHCP snooping on the switch. DHCP snooping is a feature that prevents rogue DHCP servers from offering IP addresses to clients by filtering DHCP messages based on trusted and untrusted ports1.
* Configure VLANs 100, 110, and 120 as DHCP snooping VLANs. This means that DHCP snooping will be applied to these VLANs and any untrusted DHCP messages received on these VLANs will be dropped1.
* Configure LAG 1 as a trusted port for DHCP snooping. This means that any DHCP messages received on LAG 1 will be allowed and not filtered by DHCP snooping. LAG 1 is assumed to be connected to a legitimate DHCP server or a router that relays DHCP requests to a legitimate DHCP server1.
Option B is incorrect because it does not enable DHCP snooping on the switch or configure VLANs 100, 110, and 120 as DHCP snooping VLANs. Option C is incorrect because it does not configure LAG 1 as a trusted port for DHCP snooping. Option D is incorrect because it does not enable DHCP snooping on the switch or configure LAG 1 as a trusted port for DHCP snooping. References: 1

質問 # 74
What is a primary benefit of BSS coloring?
- A. BSS color tags are applied to WI-Fi channels and can reduce the threshold tor interference
- B. BSS color tags improve security by identifying rogue APS and tagging them as threats.
- C. BSS color tags are applied on the wireless controllers and can reduce the threshold for interference_
- D. BSS color tags improve performance by allowing APS on the same channel to be farther apart
正解：A
解説：
BSS coloring is a mechanism that allows Wi-Fi 6 devices to mark each frame with a color code that identifies the BSS (Basic Service Set) it belongs to. This helps differentiate between frames from different BSSs that share the same channel and avoid unnecessary collisions and backoffs.
BSS coloring also introduces an adaptive threshold for interference, which means that Wi-Fi 6 devices can adjust the signal strength value that determines whether a channel is busy or not based on the current network environment. This allows for more efficient use of spectrum and higher throughput in dense scenarios.

A customer is using Aruba Cloud Guest, but visitors keep complaining that the captive portal page keeps coming up after devices go to sleep Which solution should be enabled to deal with this issue?
- A. MAC Caching under the splash page
- B. MAC Caching under the WLAN
- C. MAC Caching under the user-role
- D. Wireless Caching under the splash page
正解：A
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.
質問 # 76
For an Aruba AOS10 AP in mixed mode, which factors can be used to determine the forwarding role assigned to a client? (Select two.)
- A. Client IP address
- B. 802.1X authentication result
- C. Client MAC address
- D. Client SSID
- E. Client VLAN
正解：A、D
解説：
Client IP address: This factor can be used to determine if the client is on the same VLAN as the AP or not. If the client IP address is on the same VLAN as the AP, then the client traffic is bridged locally. If the client IP address is on a different VLAN than the AP, then the client traffic is forwarded to the gateway cluster through a secure tunnel.
Client VLAN: This factor can be used to determine if the client belongs to a specific VLAN or not.
If the client belongs to a specific VLAN, then the client traffic is forwarded to that VLAN based on its IP address and security profile.
質問 # 77
You are deploying a bonded 40 MHz wide channel What is the difference in the noise floor perceived by a client using this bonded channel as compared to an unbonded 20MHz wide channel?
- A. 2dB
- B. 8dB
- C. 4dB
- D. 3dB
正解：D
解説：
The difference in the noise floor perceived by a client using a bonded 40 MHz wide channel as compared to an unbonded 20 MHz wide channel is 3 dB. The noise floor is the level of background noise in a given frequency band. When two adjacent channels are bonded, the noise floor increases by 3 dB because the bandwidth is doubled and more noise is captured. The other options are incorrect because they do not reflect the correct relationship between bandwidth and noise floor.

質問 # 78
You are deploying Aruba CX 6300's with the customers requirement to only allow one (1) VoIP phone and one (1) device.
The following local role gets assigned to the phone port-access rote VoIP device-traffic-class voice What set of commands best fits this requirement?
- A. interface 1/1/1
aaa authentication port-access client-limit 1
aaa authentication port-access auth-mode device-mode - B. interface 1/1/1
aaa authentication port-access client-limit multi-domain 2
aaa authentication port-access auth-mode multi-domain - C. interface 1/1/1
aaa authentication port-access auth-mode multi-domain - D. interface 1/1/1
aaa authentication port-access client-limit 2
aaa authentication port-access auth-mode client-mode
正解：B
解説：
Aruba CX 6300 switches support various features to control the port access for different types of devices, such as client mode, device mode, and multidomain mode. These features can help limit the number of clients that can connect to a port and prevent unauthorized devices from accessing the network.
This is because option C shows how to configure the client limit and the auth-mode for a specific port using the interface command and the aaa authentication port-access command. The client limit specifies the maximum number of clients that can connect to a port. The auth-mode specifies the authentication mode for the port. In this case, option C sets both parameters to multi-domain mode, which allows only one voice device and one data device to be authenticated on a port.

質問 # 80
What is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches?
- A. Switch authentication and local forwarding of the voice traffic
- B. Switch authentication and user-based tunneling of the voice traffic.
- C. Controller authentication and port-based tunneling of all traffic
- D. Central authentication and port-based tunneling of the voice traffic.
正解：A
解説：
Explanation
This is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches. Dynamic segmentation is a feature that allows AOS-CX switches to tunnel user traffic to a controller or another switch based on user roles and policies. For voice traffic, it is recommended to use switch authentication and local forwarding, which means the voice devices are authenticated by the switch and their traffic is forwarded locally without tunneling. This reduces latency and jitter for voice traffic and improves voice quality. The other options are incorrect because they either use central authentication or tunneling, which are not optimal for voice traffic. References:

- A. UCC Service
- B. LLDP-MED
- C. SRTP
- D. CSMA
正解：A
解説：
The capability that enables plug-and-play provisioning of access points in an HPE Aruba network is the UCC Service. The UCC Service is a cloud-based service that allows the access points to automatically discover and connect to the Aruba Central management platform without any manual intervention. The UCC Service also provides zero-touch configuration, firmware updates, and monitoring for the access points.
質問 # 82
You are are doing tests in your lab and with the following equipment specifications:
* AP1 has a radio that generates a 16 dBm signal.
* AP2 has a radio that generates a 13 dBm signal.
* AP1 has an antenna with a gain of 8 dBi.
* AP2 has an antenna with a gain of 12 dBi. The antenna cable for AP1 has a 4 dB loss. The antenna cable for AP2 has a 3 dB loss.
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for AP1?
- A. 40 dBm
- B. 15 dBm
- C. -9 dBm
- D. 20 dBm
正解：D
解説：
The Equivalent Isotropic Radiated Power (EIRP) is the measured radiated power of an antenna in a specific direction. It is also called Equivalent Isotropic Radiated Power. It is the output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna. It is represented in dB2. The formula for EIRP is:
EIRP=PT−Lc+Ga
where PT is the output power of the transmitter in dBm, Lc is the cable and connector loss in dB, and Ga is the antenna gain in dBi.
For AP1, the EIRP can be calculated as:
EIRP=16−4+8=20 dBm
Therefore, the answer B is correct.
質問 # 83
What is a primary benefit of BSS coloring?
- A. BSS color tags improve security by identifying rogue APs and removing them from the network.
- B. BSS color tags improve performance by allowing clients on the same channel to share airtime.
- C. BSS color tags are applied to client devices and can reduce the threshold for interference
- D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
正解：C
解説：
This is the correct definition of BSS coloring and its primary benefit. BSS coloring is a mechanism that assigns a color code to each BSS (Basic Service Set), which consists of an AP and its associated clients.
The color code is added to the PHY header of each frame transmitted by the AP or the client.
BSS coloring helps reduce co-channel interference by allowing devices to differentiate between frames from their own BSS and frames from neighboring BSSs that use the same channel.
Devices can then adjust their threshold for interference based on the color code and decide whether to transmit or defer based on the channel status. The other options are incorrect because they either describe different mechanisms or benefits of BSS coloring or use incorrect terms.

What should you use?
- A. Multiple Pre-Shared Keys (MPSK) with WPA3-AES
- B. Clearpass with WPA3-AES
- C. Clearpass with WPA3-PSK
- D. Multiple Pre-Shared Keys (MPSK) Local
正解：D
解説：
MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support
802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

質問 # 86
Your manufacturing client is deploying two hundred wireless IP cameras and fifty headless scanners in their warehouse. These new devices do not support 802.1X authentication.
How can HPE Aruba enhance security for these new IP cameras in this environment?
- A. MPSK provides for each device in the WLAN to have its own unique pre-shared Key.
- B. Use MPSK Local to automatically provide unique pre-shared Keys for devices.
- C. Aruba ClearPass performs the 802.1X authentication and installs a certificate.
- D. MPSK Local will allow the cameras to share a rey and the scanners to share a different
正解：A
解説：
The best option to enhance security for the new IP cameras and scanners in this environment is C. MPSK provides for each device in the WLAN to have its own unique pre-shared key.
MPSK stands for Multi Pre-Shared Key, and it is a feature that allows different devices to connect to the same SSID with different pre-shared keys. This improves the security and scalability of the network, as each device can have its own key and role without requiring 802.1X authentication or an external policy engine.MPSK can be configured either locally on the AP or centrally on Aruba Central12.
The other options are incorrect because:
* A. MPSK Local is a feature that allows the user to configure 24 PSKs per SSID locally on the device.
These local PSKs would serve as an extension of the base MPSK functionality.However, MPSK Local is not suitable for this scenario, as it can only support up to 24 devices per SSID, while the client has
250 devices1.
* B. Aruba ClearPass is a network access control solution that can perform 802.1X authentication and install certificates for devices.However, this option is not feasible for this scenario, as the new IP cameras and scanners do not support 802.1X authentication3.
* D. MPSK Local will not allow the cameras to share a key and the scanners to share a different key.
MPSK Local will assign a different key to each device, regardless of their type.Moreover, MPSK Local
* can only support up to 24 devices per SSID, while the client has 250 devices1.
質問 # 87
A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server. The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What statements are correct regarding the ERSPAN session that needs to be established on an AOS-CX switch? (Select two)
- A. The encapsulation protocol used is GRE.
- B. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
- C. On the source AOS-CX switch, the destination specified is the administrators desktop
- D. The encapsulation protocol used is VXLAN.
- E. The encapsulation protocol is UDP.
正解：A、C
解説：
These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator's desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc. The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.
