NEW QUESTION # 10
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?
- A. Both routes will be suppressed until the path conflict has been resolved.
- B. The router will prefer the E1 path.
- C. The router will use Doth paths equally utilizing ECMP.
- D. The router will prefer the E2 path.
Answer: B
Explanation:
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.
NEW QUESTION # 11
A customer is running out of IP addresses in a network segment. What will happen If they add an additional IPsubnet to the same VLAN?
- A. Broadcasts for me two subnets win arrive on all ports in the same VLAN
- B. Users can reach each other and establish PTP traffic without passing an L3 point in the same VLAN
- C. This would result in a single SVI using two subinterfaces.
- D. IGMP will not work in both of the subnets in the same VLAN
Answer: B
Explanation:
Adding an additional IP subnet to the same VLAN means that devices configured with either subnet can communicate at Layer 2 without the need for routing. This is because they are on the same VLAN and thus in the same broadcast domain. However, to communicate between subnets, an L3 device or inter-VLAN routing would be required.
NEW QUESTION # 12
Refer to the exhibit.
Which statement is true?
- A. The client performed passive scanning
- B. The client is failing 802.1X authentication
- C. The client used an incorrect passphrase
- D. The client is using BSS Fast Transition
Answer: B
Explanation:
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.
NEW QUESTION # 13
What directly affects the MCS used by wireless stations? (Select two.)
- A. SNR
- B. retry rate
- C. channel utilization
- D. number of connected clients
- E. frequency band
Answer: A,E
Explanation:
The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal-to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.
NEW QUESTION # 14
A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile cased on best practices. Why do they have an equal split of their 120 APs across the primary and secondary gateway clusters?
- A. The primary gateway cluster is a heterogeneous cluster with six nodes.
- B. The secondary gateway cluster is a homogeneous cluster with six nodes.
- C. The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled
- D. The primary and secondary gateway clusters are up. and the cluster preemption is enabled
Answer: C
Explanation:
When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.
NEW QUESTION # 15
A customer is deploying a new warehouse with AP-634 APs inthe unitedStates with mobile devices that can operate in the 6GHz spectrum All testing and RF analyses were performed during the POC using AP-635 APs In a different location During the deployment, they noticed fewer 6GHz channels were broadcasting in the air.
Why would the AP-634 deployment have a lesser amount of broadcasting channels?
- A. The AP-634 APs do not have an advanced subscription.
- B. The AP-635 APs received different allowable 6GHz channels from the AFC service versus the AP-634 APs due to the POC running in a different location.
- C. The AP-634 AP's persona was configured in the Central group as Standard Power.
- D. The AP-634 APs cannot broadcast an 6Gnz channels due to regulatory restrictions.
Answer: B
Explanation:
In the United States, the operation in the 6GHz band for Wi-Fi devices such as the AP-634 and AP-635 is regulated by the Automated Frequency Coordination (AFC) system, which determines the channels that can be used based on the location. Since the Proof of Concept (POC) was conducted in a different location using AP-635 APs, the allowable channels identified by the AFC service for that location would be different than the channels allowed for the actual deployment location of the AP-634 APs. This would result in a different set of broadcasting channels being available for use in the new warehouse deployment.
NEW QUESTION # 16
in a WLAN network with a tunneled SSID. you see the following events in HPE Aruba Networking Central:
The customer asks you to investigate log messages What should you tell them?
- A. This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18
:Od. You should upgrade the client WLAN driver. - B. This indicates a security issue. The client with a MAC address ending with 37 18;0d Is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network.
- C. There is a roaming issue Enable Fast Roaming 802.11r and OKC to resolve the issue.
- D. This is normal, expected behavior. No further actions are needed.
Answer: D
Explanation:
The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.
NEW QUESTION # 17
You are testing the use of the automated port-access role configuration process using RadSec authentication over VXLAN. During your testing you observed that the RadSec connection will fan during the digital certificate exchange What would be the cause of this Issue?
- A. The RADIUS TCP packets are Being dropped and the TLS tunnel is not established.
- B. The RadSec server was defined on the switch using an IPv6 address that was unreachable
- C. Tracking mode was set to "dead-only", and the RadSec server was marked as unreachable.
- D. The switch is configured to establish a TLS connection with a proxy server, not the radius server.
Answer: A
Explanation:
During the testing of RadSec authentication over VXLAN, if the RadSec connection fails during the digital certificate exchange, it typically indicates an issue with the establishment of the TLS tunnel, which is required for RadSec's secure communication. The failure of TLS tunnel establishment can occur due to RADIUS TCP packets being dropped, preventing the secure exchange of digital certificates necessary for RadSec authentication. The other options, such as IPv6 address reachability, tracking mode settings, and proxy server misconfiguration, are not directly related to the failure of the TLS tunnel establishment during the certificate exchange process
NEW QUESTION # 18
Exhibit.
Which user role will be assigned when a voice client tries to connect for the first time, but the RADIUS server is unavailable?
- A. PRE_AUTH
- B. CRIT1CAL_V0ICE
- C. CRITICAl_AUTH
- D. DEFAULT_AUTH
Answer: B
Explanation:
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.
NEW QUESTION # 19
Your customer added third-party USB dongles to the USB ports of their AOS 10 access points. The customer uses AP-615 and AP-635 Each AP is connected with a Cat 6A cable to a CX 6300F Class 4 PoE switch All APs are in the same group in HPE Aruba Networking Central and share the same configuration However, many of the dongles do not come up.
Which option will solve this issue?
- A. Perform a "poe disable" followed by a "poe enable" for the switch ports which connect to the APs so that the APs reboot.
- B. Create two separate service profiles in the loT tab of the Central configuration settings.
- C. Move the AP-635 access points to a different group in Central to configure the dongles separately from the AP-615.
- D. Replace the Class a PoE switches with Class 6 PoE switches.
Answer: D
Explanation:
USB dongles often require additional power, which may exceed the power delivery capabilities of Class 4 PoE switches. Aruba AP-615 and AP-635 are designed to work with USB dongles that require additional power for proper operation. Since the Cat 6A cable can support higher power levels, replacing the Class 4 PoE switches with Class 6 PoE switches, which can deliver higher power, should resolve the issue with the dongles not powering up.
NEW QUESTION # 20
Exhibit.
Which statement is true given the following CLI output from a CX 6300?
- A. There are no active fabric clients on the CX switch with RD 172.16.10.1
- B. A wired client with IP address 10.203 1.100 is on a remote CX 6300 in the fabric with loopback IP address 172.21.11.2.
- C. The overlay loopbacK addresses are advertised in the faerie with 2d-bit subnet masks
- D. A wired client with IP address 10 203 1 100 has a host route that is not being properly advertised
Answer: B
Explanation:
The CLI output provided shows routing information from a CX 6300 switch. The output under "VRF: default" shows various IP routes, including a route for 10.203.1.100/32 with a next hop of 172.21.11.2. This indicates that the route to the client with IP address 10.203.1.100 is known in the network and is reachable via another device in the fabric, which has the loopback IP address 172.21.11.2. Since the route is present in the routing table, it means that the client is known and active within the fabric network.

MU-MIMO allows multiple users to receive multiple data streams simultaneously, improving the overall efficiency of the network, especially in dense environments where VoIP applications need consistent and reliable connectivity.
NEW QUESTION # 24
The ACME company has an AOS-CX 6200 VSF switch slack with an uplink over subscription ratio of 9.6:1.
They have indicated that their low-priority TCP traffic has been flagged with a DSCP marking coloring them yellow.
Refer to the exhibit.
They are considering adding two more nodes to thestack without adding any additional uplinks due to existing wiring constraints.One of their architects has suggested adding the following configuration:
What would be the impact of applying the acmethreshold profile as shown? (Select two.)
- A. Yellow-flagged TCP traffic egressing LAG1 will be subject to drop probability
- B. VoIP packets egressing any queue on LAG1 will more likely be protected from uplink over-utilization
- C. All upper-layer protocol traffic egressing LAG1 will be subject to drop probability.
- D. Only VoIP packets egressing queue 5 on LAG1 will likely be protected from uplink over-utilization.
- E. All TCP traffic egressing LAG1 wail be subject to drop probability
Answer: A,C
Explanation:
Applying the 'acmethreshold' profile as shown in the exhibit would set a minimum and maximum threshold for queue 0, which affects the drop probability for traffic that exceeds these thresholds. The yellow marking indicates a medium drop precedence, so yellow-flagged traffic would be more likely to be dropped when congestion occurs, and the uplink is over-utilized. This action is intended to protect higher-priority traffic, such as VoIP, by giving it a lower probability of being dropped.

NEW QUESTION # 27
You are troubleshooting a WLAN deployment with APs and gateways set up with an 802.1X tunneled SSIO.
End-users are complaining that they can't connect to die enterprise SSID. Which possible AP tunnel states could be the cause of the Issue? (Select two.)
- A. SM_STATE_SURVIVING
- B. SM_STATE_CONNECTED
- C. SM_STATE_CONNECTING
- D. SM_STATE_SURVIVED
- E. SM_STATE_RE KEYING
Answer: C,E
Explanation:
When troubleshooting a WLAN with 802.1X tunneled SSID issues, AP tunnel states indicate the status of the connection between the AP and the gateway/controller. The states 'SM_STATE_REKEYING' and
'SM_STATE_CONNECTING' could indicate transitional states where the connection has not been fully established, hence users might face issues connecting to the SSID. 'SM_STATE_REKEYING' implies that the AP is in the process of re-establishing encryption keys, while 'SM_STATE_CONNECTING' indicates that the AP is trying to establish a connection with the controller or gateway. These states could lead to temporary connectivity issues until the state transitions to 'SM_STATE_CONNECTED'.
NEW QUESTION # 28

Reviewing the settings above, watch change is needed to align with best practices?
- A. Disable 802 11r.
- B. increase 5Gnz TX power range Min/Max.
- C. Disable 802 11k.
- D. increase 5 GHz wireless coverage tuning to Aggressive.
Answer: B
Explanation:
To address connectivity issues when students are working outdoors, increasing the transmission (TX) power range for the 5GHz radios can help improve signal strength and coverage. The setting shown indicates a conservative approach to power settings, which might not provide sufficient coverage for outdoor areas. By increasing the power range, you can extend the wireless signal reach, which aligns with best practices for outdoor wireless coverage.
NEW QUESTION # 29
Which statements accurately describe OSPF Graceful Restart (when the restarting router is able to Keep its forwarding tables across the restart)? (Select two.)
- A. You must ensure your VSF stack has a secondary member when acting as a GR helper
- B. OSPF Routers listen for Grace-LSAs on each network segment where there is an OSFP adjacency.
- C. Bidirectional Forwarding Detection for OSPF and GR are mutually exclusive features.
- D. VSF Failover and Graceful-Restart require a VSF secondary member in the VSF stack
- E. The GR helper role is supported on AOX-CX 6100 switches.
Answer: B,E
Explanation:
Graceful Restart (GR) allows a router to continue forwarding packets while it restarts its OSPF process. The GR helper role on AOS-CX switches supports routers during this process. OSPFrouters listen for Grace-LSAs to identify neighbors undergoing a graceful restart, maintaining adjacencies with those routers to allow uninterrupted forwarding.
