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

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:

• Checksum: Checksum is a 16-bit field that is used to verify the integrity of the IP header. Checksum is calculated by the source device and verified by the destination device based on the values of all fields in the IP header. Checksum does not mitigate Layer 3 route loops because it does not limit the number of hops that a packet can traverse.

  
  

• Protocol: Protocol is an 8-bit field that indicates the type of payload carried by the IP datagram. Protocol identifies the upper-layer protocol that uses IP for data transmission, such as TCP Transmission Control Protocol (TCP) Transmission Control Protocol (TCP) is a connection-oriented transport layer protocol that provides reliable, ordered, and error-checked delivery of data between applications on different devices. TCP uses a three-way handshake to establish a connection between two endpoints, and uses sequence numbers, acknowledgments, and windowing to ensure data delivery and flow control. TCP also uses mechanisms such as retransmission, congestion avoidance, and fast recovery to handle packet loss and congestion. TCP segments data into smaller units called segments, which are encapsulated in IP datagrams and have a specific format that contains fields such as source port, destination port, sequence number, acknowledgment number, header length, flags, window size, checksum, urgent pointer, options, data, etc. TCP segments can be verified by using commands such as telnet, ftp, ssh, debug ip tcp transactions, etc ., UDP User Datagram Protocol (UDP) User Datagram Protocol (UDP) is a connectionless transport layer protocol that provides

  1. iP default-gateway 10.4.5.1

  2. ip route 0 0 0.070 10.4 5.1 vrf mgmt

  C. ip route 0.0 0 0/0 10.4.5.1

  D. default-gateway 10.4.5.1

  
  

  
  
  Answer: C

  
  

  
  Explanation:

  
  

  The command that is used to set a default route to 10.4.5.1 on an Aruba CX switch when in-band management using an SVI is being used is ip route 0.0 0 0/0 10.4.5.1. This command specifies the destination network address (0.0 0 0) and prefix length (/0) and the next-hop address (10.4.5.1) for reaching any network that is not directly connected to the switch. The default route applies to the default VRF Virtual Routing and Forwarding. VRF is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. VRFs are typically used to segment network traffic for security, privacy, or administrative purposes., which is used for in-band management traffic that goes through an SVI Switch Virtual Interface. SVI is a virtual interface on a switch that allows the switch to route packets between different VLANs on the same switch or different switches that are connected by a trunk link. An SVI is associated with a VLAN and has an IP address and subnet mask assigned to it12. References:

  Question: 177

  A hospital uses a lot of mobile equipment for the diagnosis and documentation of patient data.

  
  

  What Is the ideal access switch for this large hospital with distribution racks of over 400 ports in a single VSF stack?

  
  

  1. CX 6300

  2. OCX 6400

  3. OCX 6200

  4. OCX 6100

  
  

  
  
  Answer: A

  
  

  
  Explanation:

  
  

  The ideal access switch for a large hospital with distribution racks of over 400 ports in a single VSF stack is the CX 6300.

  
  

  This switch provides the following benefits:

  
  

• The CX 6300 supports up to 48 ports per switch and up to 10 switches per VSF stack, allowing for a total of 480 ports in a single stack. This meets the requirement of having over 400 ports in a single VSF stack.

  
  

• The CX 6300 supports high-performance switching with up to 960 Gbps of switching capacity and up to 714 Mpps of forwarding rate. This meets the requirement of having high throughput and low latency for mobile equipment and patient data.

  
  

• The CX 6300 supports advanced features such as dynamic segmentation, policy-based routing, and role-based access control. These features enhance the security and flexibility of the network by applying different policies and roles to different types of devices and users.

  
  

• The CX 6300 supports Aruba NetEdit, a network configuration and orchestration tool that simplifies the management and automation of the network. This reduces the complexity and human errors involved in network configuration and maintenance.

  
  

  The other options are not ideal because:

  
  

• OCX 6400: This switch is designed for data center applications and does not support VSF stacking. It also does not support dynamic segmentation or policy-based routing, which are useful for network security and flexibility.

  
  

• OCX 6200: This switch is designed for small to medium-sized businesses and does not support VSF stacking. It also has lower switching capacity and forwarding rate than the CX 6300, which may affect the performance of the network.

  
  

• OCX 6100: This switch is designed for edge applications and does not support VSF stacking. It also has lower switching capacity and forwarding rate than the CX 6300, which may affect the performance of the network.

  2. Template group

  3. Default group

  4. Ul group

  5. ESP group

  
  

  
  
  Answer: B,C

  
  

  
  Explanation:

  
  

  Aruba Central allows you to create device configuration groups that define common settings for devices within each group. You can create different types of groups depending on your network requirements and management preferences.

  
  

  Two types of groups that you can define in Aruba Central during group creation are:

  
  

• Template group: A template group allows you to create configuration templates using variables and expressions that can be applied to multiple devices or device groups. Template groups provide flexibility and scalability for managing large-scale deployments with similar configurations.

  
  

• Default group: A default group is automatically created when you add devices to Aruba Central for the first time. The default group contains basic configuration settings that are applied to all devices that are not assigned to any other group. You can modify or delete the default group as needed.

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: 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.
