What is the correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1?
A. ip-route 10.2.10.0/24 172.16.1.1
B. ip route 10.2.10.0.255.255.255.0 172.16.1.1 description aruba
C. ip route 10.2.10.0/24.172.16.11
D. ip route-static 10.2 10.0.255.255.255.0 172.16.1.1
Explanation:
The correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1 is ip-route 10.2.10.0/24 172.16.1.1 . This command specifies the destination network address (10.2.10.0) and prefix length (/24) and the next-hop address (172.16.1 .1) for reaching that network from the switch. The other commands are either incorrect syntax or incorrect parameters for adding a static route.

Which authentication does Aruba's Captive Portal use?
A. Layer 3 authentication
B. MAC authentication
C. 802.1x authentication
D. Layer 2 authentication
Explanation:
Aruba’s Captive Portal uses Layer 3 authentication, which means that it intercepts the client’s HTTP requests and redirects them to a web page where the client can enter their credentials. The credentials are then verified by a RADIUS server or a local database before granting network access.

Where are wireless client roaming decisions made?
A. Client device
B. Virtual Controller
C. Joint decision made by the origination and destination APs
D. Aruba Central
Explanation:
Wireless client roaming decisions are made by the client device based on its own criteria, such as signal strength, noise level, data rate, etc. The network can influence the client’s roaming decision by providing information such as neighbor reports, load balancing, band steering, etc., but the final decision is up to the client.

Which statement about manual switch provisioning with Aruba Central is correct?
A. Manual provisioning does not require DHCP and requires DNS
B. Manual provisioning does not require DHCP and does not require DNS
C. Manual provisioning requires DHCP and does not require DNS
D. Manual provisioning requires DHCP and requires DNS
Explanation:
Manual provisioning is a method to add switches to Aruba Central without using DHCP or DNS. It requires the user to enter the switch serial number, MAC address, and activation code in Aruba Central, and then configure the switch with the same activation code and Aruba Central’s IP address.

A network technician is troubleshooting one new AP at a branch office that will not receive Its configuration from Aruba Central The other APs at the branch are working as expected The output of the 'show ap debug cloud-server command' shows that the "cloud conflg received" Is FALSE. After confirming the new AP has internet access, what would you check next?
A. Disable and enable activate to trigger provisioning refresh
B. Verify the AP can ping the device on arubanetworks.com
C. Verify the AP has a license assigned
D. Disable and enable Aruba Central to trigger configuration refresh
Explanation:
If the AP has internet access but does not receive its configuration from Aruba Central, one possible reason is that the AP does not have a license assigned in Aruba Central. A license is required for each AP to be managed by Aruba Central.

Which Protocol Data Unit (PDU) represents the data link layer PDU?
A. PDU1 - Signal
B. PDU2 - Frame
C. PDU3 - Packet
D. PDU4 - Segment
Explanation:
A frame is the data link layer PDU that encapsulates the network layer PDU (packet) with a header and a trailer that contain information such as source and destination MAC addresses, frame type, error detection, etc. A frame is transmitted over a physical medium such asEthernet, Wi-Fi, etc.

When using Aruba Central what can identify recommended steps to resolve network health issues and allows you to share detailed information with support personnel?
A. Overview Dashboard
B. OAlOps
C. Alerts and Events
D. Audit Trail
Explanation:
OAlOps is a feature of Aruba Central that uses artificial intelligence and machine learning to identify recommended steps to resolve network health issues and allows you to share detailed information with support personnel. OAlOps provides insights into network performance, root cause analysis, anomaly detection, proactive alerts, and automated remediation actions.OAlOps also integrates with Aruba User Experience Insight (UXI) sensors to measure and improve user experience across wired and wireless networks.

You have been asked to onboard a new Aruba 6300M in a customer deployment You are working remotely rather than on-site You have a colleague installing the switch The colleague has provided you with a remote console session to configure the edge switch You have been asked to configure a link aggregation going back to the cores using interfaces 1/1/51 and 1/1/52 The Senior Engineer of the project has asked you to configure the switch and 1Q uplink with these guidelines
1. Add VLAN 20 to the local VLAN database with name Mgmt
2. Add L3 SVl on VLAN 20 for Management using address 10 in the 10.1.1 0/24 subnet 3. Add LAG 1 using LACP mode active for the uplink
4 use vlan 20 as the native vlan on the LAG 5. Make sure the interfaces are all ON.
Which configuration script will achieve the task?
A. Edge1# conf t vlan 20 name Mgmt interface vlan 20 ip address 10.1.1.10/24 no shut interface lag 1 shut vlan access 20 lacp mode active Int 1/1/51.1/1/52 shut no routing lag 1 interface lag 1 no shut
B. Edgel# conf t vlan 20 name Mgmt interface vlan 20 ip address 10 1.1 10/24 no shut interface 1/1/51.1/1/52 shut vlan trunk native 20 vlan trunk allowed all lag 1 lacp mode active interface 1/1/51.1/1/52 no shut
C. Edgel# conf t vlan 20 name Mgmt interface vlan 20 ip address 10 1 1 10/24 no shut interface lag 1 shut vlan trunk native 20 vlan trunk allowed all lacp mode active Int 1/1/51.1/1/52 shut no routing lag 1 interface lag 1 no shut interface 1/1/51.1/1/52 no shut
D. conf t vlan 20 name Mgmt ip address 10 1 1.10/24 no shut interface lag 1 shut vlan trunk native 1 vlan trunk allowed all lacp mode active int 1/1/51.1/1/52 shut no routing interface lag 1 no shut interface 1/1/51.1/1/52 no shut
Explanation:
This configuration script will achieve the task as it follows the guidelines given by the Senior Engineer. It creates VLAN 20 with name Mgmt, adds L3 SVI on VLAN 20 with IP address 10.1.1.10/24, creates LAG 1 with LACP mode active for the uplink, uses VLAN 20 as the native VLAN on the LAG, and ensures that the interfaces are all ON.

What does a slow amber-flashing Stack-LED indicate?
A. One switch has a stacking failure.
B. A port has a stacking failure Stacking mode Is not selected
C. Stacking mode selected
D. Stacking is synchronizing Please wait
Explanation:
A slow amber-flashing Stack-LED indicates that stacking mode is selected on the switch. This means that the switch is ready to join a stack or form a new stack if no other switches are present.

When using the OSPF dynamic routing protocol on an Aruba CX switch, what must match on the neighboring devices to exchange routes?
A. Hello timers
B. DR configuration
C. ECMP method
D. BDR configuration
Explanation:
OSPF Open Shortest Path First. OSPF is a link-state routing protocol that uses a hierarchical structure to create a routing topology for IP networks. OSPF routers exchange routing information with their neighbors using Hello packets, which are sent periodically on each interface. To establish an adjacency Adjacency is a relationship formed between selected neighboring routers for the purpose of exchanging routing information., OSPF routers must agree on several parameters, including Hello timers, which specify how often Hello packets are sent on an interface. If the Hello timers do not match between neighboring routers, they will not form an adjacency and will not exchange routes.

When measuring signal strength, dBm is commonly used and 0 dBm corresponds to 1 mW power. What does -20 dBm correspond to?
A. .-1 mW
B. .01 mw
C. 10 mW
D. 1mW
Explanation:
dBm is a unit of power that measures the ratio of a given power level to 1 mW. The formula to convert dBm to mW is: P(mW) = 1mW * 10^(P(dBm)/10). Therefore, -20 dBm corresponds to 0.01 mW, as follows: P(mW) = 1mW * 10^(-20/10) = 0.01 mW
