NEW QUESTION # 75
You are testing a Captive Portal for wired guest access and are seeing the self-signed certificate warning below.
Which statement is true?
Answer: A
Explanation:
The correct answer is A. A public CA signed certificate should be deployed. The browser warning appears because the captive portal is presenting a self-signed certificate that the client device does not trust. For guest access, client devices are usually unmanaged and cannot be expected to already trust an internal or self-signed certificate authority. HPE Aruba Networking documentation for captive portal deployments recommends that production environments obtain and install a certificate issued for the site or domain by a well-known Certificate Authority. This avoids browser trust warnings and gives guest users confidence that they are connecting to the correct portal. Option B is incorrect because disabling HTTPS and using HTTP would reduce security and expose portal traffic. Option C may work only for managed devices where the self-signed or private CA can be pushed into the trust store, but that is not practical for open wired guest access. Option D can be valid for internal managed users, but for guests, a public trusted CA certificate is the best answer.
NEW QUESTION # 76
A technician installed a new 550 series access point, which is cabled back to a CX 6000 series switch. However, there are no lights on the AP. What could cause this?
Answer: D
Explanation:
The 550 series access point requires Power over Ethernet from the switch to power on. If PoE is disabled on the CX 6000 switch interface, the access point will not receive power, resulting in no indicator lights.
NEW QUESTION # 77
A network operator is troubleshooting an application that sends a large amount of data using UDP. Users are complaining that the data is arriving corrupted. The operator states that UDP itself cannot fix this.
Why is this statement correct?
Answer: C
NEW QUESTION # 78
What is modulated to transmit data over a multi-mode cable?
Answer: D
Explanation:
The correct answer is B. Light. Multi-mode cable refers to multi-mode fiber-optic cabling. In fiber-optic transmission, data is carried using light through the fiber core. HPE Aruba Networking's transceiver documentation explains that multimode fibers have thicker fiber cores and can transport light in multiple modes. The same HPE Aruba Networking transceiver guidance discusses optical transceivers transmitting light pulses and managing light loss across fiber-optic cabling. Therefore, in the context of multi-mode fiber, the signal being modulated to represent data is light. Option A is incorrect because radio is used in wireless transmission, not fiber-optic cabling. Option C is incorrect because voltage is associated with electrical copper cabling, such as twisted-pair Ethernet, rather than optical fiber. Option D is incorrect because pressure is not used as the signaling method for standard Ethernet fiber links. This question is focused on Layer 1 media behavior, and multi-mode fiber is a Physical Layer medium that transports optical signals between network transceivers.
NEW QUESTION # 79
You have configured the following on a Core-1 HPE Aruba Networking CX switch for primary and secondary ISP connectivity:
Core-1(config)# ip route 0.0.0.0/0 10.1.251.2
Core-1(config)# ip route 0.0.0.0/0 10.1.252.2 distance 10
The default route via 10.1.251.2 stopped working, and no failover happened. The ISP reported a broken fiber on the path of an upstream device.
In what condition should the route fail over to the 10.1.252.2 router?
Answer: C
Explanation:
The correct answer is D. When 10.1.251.2 is no longer in the routing table. The configuration shows two static default routes to the same destination, 0.0.0.0/0. The first route uses the default administrative distance, while the second route has a higher administrative distance of 10, making it a floating static route. HPE Aruba Networking AOS-CX documentation for static routing states that the distance option sets the administrative distance associated with a static route, with a default of 1 and a range of 1-255. Because lower administrative distance is preferred, the route through 10.1.251.2 remains active as long as it is valid in the routing table. The backup route through 10.1.252.2 becomes active only when the preferred route is removed or no longer installed. A remote upstream fiber break might not remove the directly reachable next hop from the routing table, which explains why failover did not occur. BFD tracking could improve failure detection, but the condition for this configured floating static route to take over is loss of the primary route from the routing table.
