NEW QUESTION # 66
You are checking the interface details for an access point that cannot reach HPE Aruba Networking Central.
After reviewing the following output, which statement is true?
Interface 1/1/16 is down
Admin state is up
State information: Waiting for link
Link state: down for 5 seconds
Link transitions: 0
Description:
Hardware: Ethernet, MAC Address: 38:bd:7a:6d:73:7f
MTU 1500
Type 1GbT
Full-duplex
qos trust dscp
Speed 0 Mb/s
Auto-negotiation is on
Energy-Efficient Ethernet is disabled
Flow-control: off
Error-control: off
MDI mode: none
VLAN Mode: native-untagged
Native VLAN: 10
Allowed VLAN List: 10,20,30
Rate collection interval: 300 seconds
- A. Layer 2 QoS markings from the AP will be trusted.
- B. The interface has been administratively disabled.
- C. VLANs 10, 20, and 30 are 802.1Q tagged.
- D. The link on interface 1/1/16 is not established.
Answer: D
Explanation:
The correct answer is D. The link on interface 1/1/16 is not established. The output clearly states Interface 1/1
/16 is down, Admin state is up, and State information: Waiting for link. This means the port is enabled administratively, but the physical link is not up. HPE Aruba Networking AOS-CX show interface documentation displays these fields to show operational and administrative interface status, including examples where the interface is down while the admin state remains up. Option A is incorrect because the output says qos trust dscp, which trusts Layer 3 DSCP markings, not Layer 2 CoS markings. Option B is incorrect because Admin state is up; an administratively disabled interface would be shut down. Option C is incorrect because the output shows VLAN Mode: native-untagged and Native VLAN: 10; native VLAN 10 is untagged, while the allowed VLAN list shows VLANs permitted on the trunk. Since the port is waiting for link, the immediate verified issue is that the physical link is not established

NEW QUESTION # 70
A Network Technician is configuring an access layer switch (ALS) to connect to a core switch.
The connection uses two physical links that need to be bundled into a Link Aggregation Group (LAG) for increased bandwidth and redundancy. The LAG will function as a VLAN trunk to carry both Staff (VLAN 100) and Guest (VLAN 200) traffic. The technician must also enable RSTP for loop prevention.
Initial State:
* The switch is in its factory default state, connected via the console.
* The physical links are on ports 1/1/47 and 1/1/48.
Required Configuration:
* Create VLAN 100 and VLAN 200.
* Enable Rapid Spanning Tree Protocol (RSTP).
* Create LAG interface `lag 1`.
* Configure `lag 1` to use LACP (active mode).
* Add ports 1/1/47 and 1/1/48 to `lag 1`.
* Configure `lag 1` as a VLAN trunk, allowing VLANs 100 and 200.
* Enable the physical ports and the LAG interface.
Which configuration set correctly implements all the specified Layer 2 requirements?
- A. vlan 100
vlan 200

NEW QUESTION # 71
Which statement about out-of-band management is true?
- A. Provides better security and reliability than in-band management.
- B. Prone to congestion issues from user network traffic.
- C. Simpler to implement than in-band management.
- D. It shares the same network path as user data.
Answer: A
Explanation:
Out-of-band management uses a separate dedicated management network, isolated from production user traffic. This improves both security and reliability because management access remains available even if the main data network experiences congestion or failures.
NEW QUESTION # 72
What is a characteristic of a static route?
- A. Must be manually configured
- B. Responsive to network changes
- C. High processing overhead
- D. Automatically learned
Answer: A
Explanation:
The correct answer is A. Must be manually configured. HPE Aruba Networking AOS-CX documentation states that static routes are manually configured in the routing table. A static route defines a destination network and the next-hop address or exit interface that the switch should use to forward traffic. Static routes are useful in small, simple, or predictable networks because they are straightforward and do not require a dynamic routing protocol to exchange route information. Option B is incorrect because automatically learned routes are associated with dynamic routing protocols, such as OSPF or BGP, not static routing. Option C is incorrect because static routes usually have low processing overhead compared to dynamic routing protocols, since the switch does not need to run neighbor discovery, exchange routing updates, or calculate topology changes. Option D is incorrect because static routes do not automatically respond to network topology changes unless supported by an additional tracking mechanism or manually changed by an administrator.
Therefore, the defining characteristic of a static route is manual configuration.
NEW QUESTION # 73
Which is an example of half-duplex communication?
- A. Telephone system
- B. FM radio broadcast
- C. Fibre-optic pair
- D. Push-to-talk radio
Answer: D
Explanation:
Push-to-talk radios operate in half-duplex mode, allowing communication in only one direction at a time while the other party waits to respond.
NEW QUESTION # 74
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?
- A. When the default route graceful-restart timer expires.
- B. When the BFD session terminates on 10.1.251.2.
- C. When uplink-failure-detection enables the 10.1.252.2 route.
- D. When 10.1.251.2 is no longer in the routing table.
Answer: D
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.
NEW QUESTION # 75
A new firewall for the default gateway is connected to an HPE Aruba Networking CX 6300 switch. The security administrator has requested that you configure the Layer 3 switch without a bridged port.
How can this be done on an HPE Aruba Networking switch?
- A. interface 1/1/1
no routing
vlan access 1
ip address 10.10.10.1/29
no shutdown - B. interface 1/1/1
no routing
ip address 10.10.10.1/29
no shutdown - C. interface 1/1/1
routing
ip address 10.10.10.1/29
no shutdown - D. interface 1/1/1
routing
vlan access 1
ip address 10.10.10.1/29
no shutdown
Answer: C
Explanation:
The correct answer is D. To configure a physical interface as a Layer 3 routed port on an HPE Aruba Networking CX 6300 switch, the interface must be placed in routing mode and assigned an IP address directly. This creates a routed interface rather than a bridged Layer 2 port. HPE Aruba Networking AOS-CX examples show routed physical interfaces configured with routing, followed by an ip address, and then no shutdown. The same examples contrast this with Layer 2 ports, which use no routing and VLAN commands such as vlan access or vlan trunk. Option A is incorrect because no routing makes the interface a Layer 2 interface, so assigning an IP address directly is not the correct routed-port configuration. Options B and C are incorrect because vlan access 1 configures the port as a bridged access port. The requirement specifically says the switch should be configured without a bridged port, so the correct CX configuration is a routed physical interface using routing with the IP address configured directly on the port.

NEW QUESTION # 79
Which user group exists by default on an HPE Aruba Networking CX 6400 Series switch?
- A. reporting
- B. auditors
- C. read-only
- D. restricted
Answer: B
Explanation:
The correct answer is C. auditors. HPE Aruba Networking AOS-CX documentation for the 6200, 6300, and
6400 switch series identifies three built-in user groups: administrators, operators, and auditors. These built-in groups have fixed privileges. The administrators group has full privileges, including full CLI access, firmware upgrades, configuration viewing, configuration changes, and user account management. The operators group has no switch configuration privileges and is mainly limited to basic display-only access and viewing nonsensitive configuration information. The auditors group is restricted to audit-related functions. Since the question asks which user group exists by default on a CX 6400 Series switch, "auditors" is the only listed option that matches the HPE Aruba Networking AOS-CX built-in groups. The other options-read-only, restricted, and reporting-are not listed as default built-in AOS-CX user groups for the CX 6400 platform.
This makes option C the verified answer.

NEW QUESTION # 86
You have added the configuration below, but your auditor cannot execute 'view the software version' on the switch. What is the issue with the configuration you have applied?
- A. The first command in the permit CLI list was overwritten.
- B. The word audit is system-reserved and cannot be used.
- C. 'show version' is not a supported command for CX switches.
- D. The command "enable" needs to be included as the first entry.
Answer: A
Explanation:
Both permit statements use sequence number 10. On CX switches, entering another command with the same sequence number replaces the previous entry. As a result, the show version command was overwritten by the show run command.
