Question: 164

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


Answer: A


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.

Question: 165


When would you bond multiple 20MHz wide 802.11 channels?


  1. To decrease the Signal to Noise Ratio (SNR)

  2. To increase throughput between the client and AP

  3. To provision highly available AP groups

  4. To utilize high gain omni-directional antennas


Answer: B


Explanation:


Bonding multiple 20MHz wide 802.11 channels is a technique to create a wider bandwidth channel that supports higher data rate transmissions. It can increase the throughput between the client and AP by using more spectrum resources and reducing interference.

Question: 166


What is indicated by a solid amber radio status LED on an Aruba AP?


  1. Not enough PoE is provided from the switch to power both radios of the AP

  2. The radio is working in mesh mode

  3. The radio is working the 5 GHz band only.

  4. The radio is enabled in monitor or spectrum analysis mode


Answer: A

Explanation:


On an Aruba AP, a solid amber radio status LED indicates: A. Not enough PoE is provided from the switch to power both radios of the AP


When the radio status LED on an Aruba AP shows a solid amber color, it typically signifies that the PoE (Power over Ethernet) supplied by the switch is insufficient to power both radios of the AP (usually the 2.4 GHz and 5 GHz bands). This may require checking the PoE budget of the switch or using a higher-powered PoE source.


Other options, such as the radio working in mesh mode, operating only in the 5 GHz band, or being enabled in monitor or spectrum analysis mode, typically do not result in the LED showing a solid amber color.


Question: 167


What does WPA3-Personal use as the source to generate a different Pairwise Master Key (PMK) each time a station connects to the wireless network?


  1. Session-specific information (MACs and nonces)

  2. Opportunistic Wireless Encryption (OWE)

  3. Simultaneous Authentication of Equals (SAE)

  4. Key Encryption Key (KEK)


Answer: C Question: 168

Which flew in a Layer 3 IPv4 packet header is used to mitigate Layer 3 route loops?


  1. Checksum

  2. Time To Live

  3. Protocol

  4. Destination IP


Answer: B


Explanation:


The field in a Layer 3 IPv4 packet header that is used to mitigate Layer 3 route loops is Time To Live (TTL). TTL is an 8-bit field that indicates the maximum number of hops that a packet can traverse before being discarded. TTL is set by the source device and decremented by one by each router that forwards the packet. If TTL reaches zero, the packet is dropped and an ICMP Internet Control Message Protocol (ICMP) Internet Control Message Protocol (ICMP) is a network protocol that provides error reporting and diagnostic functions for IP networks. ICMP is used to send messages such as echo requests and replies (ping), destination unreachable, time exceeded, parameter problem, source quench, redirect, etc. ICMP messages are encapsulated in IP datagrams and have a specific format that contains fields such as type, code, checksum, identifier, sequence number, data, etc. ICMP messages can be verified by using commands such as ping,


traceroute, debug ip icmp, etc. message is sent back to the source device. TTL is used to mitigate Layer 3 route loops because it prevents packets from circulating indefinitely in a looped network topology. TTL also helps to conserve network resources and avoid congestion caused by looped packets.

The other options are not fields in a Layer 3 IPv4 packet header because:

Question: 179


What can be done to dynamically set the PoE Priority on a switch port when deploying IP cameras APs. and other PoE devices?


  1. Enable Quick PoE on the switch modules

  2. Enable profiling for device provisioning

  3. Configure PoE power management to Class-based Mode

  4. Configure PoE power management to Dynamic Mode

Answer: C Question: 180

Please match the use case to the appropriate authentication technology



wrong Answer: C Explanation:

Based on the information provided, here are the matches for the use case to the appropriate authentication technology:


ClearPass Policy Manager:


Authenticate users on corporate-owned Chromebook devices using 802.1X and context gathered from the network devices that they log into.


Validate devices exist in a Mobile Device Management (MDM) database before authenticating BYOD users with corporate Active Directory using certificates.


Cloud Authentication and Policy:


Add certificates to Android devices with the Aruba Onboard Application in the Google Play store that will be used for wireless authentication.

Leverage unbound Multi Pre-Shared Keys (MPSK) managed by Aruba Central to the end-users and client devices. The ClearPass Policy Manager is a comprehensive network access control (NAC) and policy management platform

that can authenticate devices using 802.1X, as well as integrate with MDM systems for device validation. The Cloud

Authentication and Policy is likely referring to cloud-based services such as Aruba Central, which can manage MPSK and distribute certificates for device authentication.


Question: 181


Make sure the interfaces are all ON.


Which configuration script will achieve the task?


  1. 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

  2. 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

  3. 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

  4. 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


Answer: C


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.

Question: 182


Based on the "snow ip route" output on an AruDaCX 8400. what type of route is "10.1 20 0/24, vrf default via

10.1.12.2. [1/0]"?


  1. local

  2. static

  3. OSPF

  4. connected


Answer: B


Explanation:


A static route is a route that is manually configured on a router or switch and does not change unless it is modified by an administrator. Static routes are used to specify how traffic should reach specific destinations that are not directly connected to the device or that are not reachable by dynamic routing protocols. In Aruba CX switches, static routes can be configured using the ip route command in global configuration mode. Based on the âshow ip routeâ output on an Aruba CX 8400 switch, the route â10.1 20 0/24, vrf default via 10.1.12.2, [1/0]â is a static route because it has an administrative distance of 1 and a metric of 0, which are typical values for static routes.
