The output of the show LACP interfaces shows the following:
What is causing this issue?
- A . The AP is configured with LACP active.
- B . Each AP interface is connected to a routed-only interface on different networks.
- C . Spanning tree and loop protect are enabled on both AP uplink ports.
- D . e0 is connected to a smart rate interface, and e is connected to a non-smart rate interface.
Your company needs to run BGP in a multi-homed configuration to two ISPs, advertising a block of public address space you own.
Which AS number would be an example of a suitable number?
- A . 64813
- B . 63472
- C . 65535
- D . 65218
B
Explanation:
For BGP in a multi-homed configuration advertising public IP blocks, the AS number should be a valid public AS number allocated by the regional internet registry (RIR). Numbers in the private AS range (64512C65534) are not suitable for public Internet announcements.
63472 falls in the public AS range (16-bit AS numbers below 64512).
64813, 65535, and 65218 are in the private or reserved range.
Therefore, 63472 is an example of a suitable public AS number.

With the given output from an HPE Aruba Networking CX 6300:
Which statement about the output above is true?
- A . The accepted AS paths are defined in the aspath-list.
- B . The defined route-map is used in BGP with neighbor remote-as export.
- C . The advertised AS paths are configured in an IP prefix-list.
- D . The route-map with aspath-list intended for iBGP peers.
A
Explanation:
The output indicates the use of an aspath-list within a route-map, which is used to filter or match accepted AS paths in BGP. The aspath-list defines which AS paths are accepted, controlling route advertisement or acceptance.
The route-map is applied to neighbor configurations to filter routes based on AS paths.
Prefix-lists filter IP prefixes, not AS paths.
Neighbor remote-as export is not a valid command.
Therefore, the aspath-list is correctly used to define accepted AS paths.

What statement about the output above is correct?
- A . The port-access role was configured with gateway-role visitor.
- B . The downloadable role was configured for gateway-role visitor.
- C . The client authenticated using dot1x.
- D . The secondary tunnel endpoint IP is 10.10.10.151
Refer to the exhibit.
Based on the output above, what is required to associate the GBP policy with a user role?
- A . Configure a user role called GBP-EMPLOYEE instead of EMPLOYEE
- B . Associate the port-access role to the GBP role using the role ID
- C . Update the port-access GBP policies to reference the EMPLOYEE role
- D . Update the entries in the class maps to reference the EMPLOYEE role
Refer to the exhibit:
A senior network architect has created the configuration above. You are implementing the setup in Building A and
C. The actual fiber distance between the building locations is 200m / 656ft utilizing OM4 cabling.
What needs to be changed in the configuration based on the actual environmental conditions to complete the installation and 7 other CX 6300 VSF stack connections in the future?
- A . Replace the 25GR optics with 10SR
- B . Replace the 25GR optics with 25LR
- C . Replace the 25GR optics with 10LR
- D . Replace the 25GR optics with 25SR
D
Explanation:
The configuration involves connecting two buildings over fiber using OM4 cabling with a distance of 200 meters. The current optics in use are 25GR (25 Gigabit Rate) optics.
For multimode fiber such as OM4, SR (Short Reach) optics are suitable for distances up to 300 meters.
In contrast, LR (Long Reach) optics are typically designed for single-mode fiber and longer distances.
Therefore, to properly support the 200m OM4 fiber link, 25SR optics should be used instead of 25GR (which are often long-reach optics).
10SR and 10LR refer to 10Gbps optics, which do not meet the 25Gbps requirement.
25LR optics are for single-mode fiber and longer distances, not multimode.

A manufacturing company depends on FTP, email, and RDP services, which are accessed locally. On Monday morning, RDP sessions are not responsive when users on the employee WLAN download their email and large files from the FTP server simultaneously. The network administrator concludes that the mobility gateway’s uplinks are congested when that happens.
Which would be the best option the network engineer can propose in the implementation plan to improve RDP responsiveness?
- A . Update the employee user role with an ACL on position 3 that puts RDP traffic to a high-priority queue and all other traffic to a low-priority queue
- B . Change the employee WLAN from tunneled to bridged so that the bottleneck in the mobility gateways is removed
- C . Set the WMM voice DSCP value on the employee WLAN to 56 and enable the RDP application layer gateway
- D . Update the spanning-tree configuration from enabled to disabled on the gateway’s link aggregation to increase the available bandwidth and avoid congestion
How does an HPE Aruba Networking CX VSX solution make the hardware replacement of a single switch a non-disruptive operation for Layer 2 configurations?
- A . By the utilization of any of the four reserved ranges as system-MAC addresses.
- B . By the VSX-sync option for synchronization of the system-MAC.
- C . By entering the primary switch system-MAC on the secondary switch.
- D . By allowing the system MAC in the ServiceOS to be changed to the original system MAC.
D
Explanation:
In HPE Aruba CX VSX, the hardware replacement of a single switch is non-disruptive for Layer 2 configurations because the system MAC address in the ServiceOS can be changed to the original system MAC address. This ensures consistent MAC address usage, avoiding disruptions in Layer 2 forwarding and preventing MAC flapping in the network.
Options involving VSX-sync or reserved system MAC ranges do not specifically address hardware replacement scenarios as effectively.
Changing the ServiceOS system MAC to match the original maintains Layer 2 stability during switch replacement.

A database administrator has reported intermittent connectivity issues with a SQL server hosted in the data center and has provided you with the source and destination IP addresses.
Which troubleshooting methodology would be the most suitable to start with?
- A . Spot the difference
- B . Follow the path
- C . Divide and conquer
- D . Top-down/Bottom-up
B
Explanation:
Comprehensive Detailed Explanation
When troubleshooting intermittent connectivity issues with known source and destination IPs, the Follow the path methodology is most suitable. This involves tracing the packet flow from source to destination step-by-step, checking each device or segment for failures.
Spot the difference compares configurations, which is less targeted here.
Divide and conquer isolates sections but follow the path is more direct for connectivity.
Top-down/bottom-up is more general troubleshooting.

While troubleshooting a scenario in which the customer has added two new line cards on an HPE Aruba Networking CX 6400 switch, the LEDs on the line card do not show light on the first card.
Which troubleshooting methodology should you use to isolate the problem?
- A . Spot the difference by comparing the switch configurations.
- B . Divide and conquer by swapping the line cards in their slot.
- C . Follow the path and check the connectivity from the access switch to the CX 6400.
- D . Replace the configuration using the previous checkpoint on the switch.
B
Explanation:
When line card LEDs do not light up, and the cards are newly installed, the best troubleshooting methodology is Divide and conquer by swapping the line cards. This method isolates the problem by testing hardware in different slots or known working units.
Spot the difference involves comparing configurations, which does not directly isolate hardware failure.
Follow the path is more suited for connectivity issues.
Replace configuration relates to software or config problems.
Hardware issues are best isolated by physically swapping components.
