1. 1In the HPE Aruba Networking spine-and-leaf reference design, what change increases east-west fabric capacity between existing leaf switches?

   1. A.Add spine switches to the fabricCorrect answer: A
   2. B.Add server access switches to the fabric
   3. C.Add VLANs to existing leaf switches
   4. D.Add VRFs to existing spine switches

   Explanation: "Spine switches are added to increase east-west fabric capacity between leaf switches." Additional spines increase interleaf fabric capacity; the other changes do not provide additional spine fabric capacity.

2. 2During staging, a CX 10000 is to receive its initial configuration automatically using ZTP. What state must the switch be in?

   1. A.A configuration with ZTP manually completed
   2. B.Factory default configurationCorrect answer: B
   3. C.A previously saved production configuration
   4. D.A running configuration copied from another switch

   Explanation: "The switch must be in the factory default configuration." ZTP requires the factory default state for this procedure.

3. 3An administrator configures a static IPv4 VXLAN on AOS-CX 10.13. Which command sets the remote VTEP address inside the VNI?

   1. A.no shutdown
   2. B.vtep-peerCorrect answer: B
   3. C.source ip
   4. D.vlan

   Explanation: "Define the IP address of the peer VTEP with the command vtep-peer." source ip sets the local tunnel source, vlan maps a VLAN, and no shutdown enables the interface.

4. 4A CX 10000 port LED flashes after initialization. Which two sources does the installation guide direct an engineer to check for the fault condition?

   1. A.The switch event log and show interface outputCorrect answer: A
   2. B.The show spanning-tree and show lacp interfaces output
   3. C.The show environment fan and show spanning-tree output
   4. D.The show lacp interfaces and show environment fan output

   Explanation: "Check the switch Event Log and show interface command output for indication of the fault condition." The event log and interface output help identify the port fault.

5. 5A network operator needs to see installed NAE agents and their individual status in the AOS-CX 10.13 Web UI. Where is that list shown?

   1. A.The Scripts panel of the Analytics Dashboard
   2. B.A single agent's time-series graph
   3. C.The Agents panel of the Analytics DashboardCorrect answer: C
   4. D.A single agent's Status panel

   Explanation: "The Agents panel in the Analytics Dashboard shows a list of the agents installed on the switch, along with the status of each agent." The dashboard's Agents panel lists installed agents and their status.

   Reference: AOS-CX 10.13 Network Analytics Engine Guide — Viewing a list of agents installed on a switch using the Web UI, page 34

6. 6An engineer tracks AOS-CX releases against the Fabric Composer 6.6 compatibility matrix. What does the matrix's Qualified label mean?

   1. A.The AOS-CX version is fully testedCorrect answer: A
   2. B.The AOS-CX version is no longer supported
   3. C.The AOS-CX version has not yet been tested
   4. D.The AOS-CX version is scheduled for mandatory removal

   Explanation: "Qualified = Fully tested." This is the stated release or compatibility requirement.

7. 7A data center uses storage traffic and ordinary lossy traffic on the same Ethernet link. Which DCB mechanism reserves bandwidth for the traffic classes?

   1. A.Data Center Bridging Exchange
   2. B.Explicit Congestion Notification
   3. C.Enhanced Transmission SelectionCorrect answer: C
   4. D.Priority-based Flow Control

   Explanation: "ETS: Enhanced Transmission Selection Defines bandwidth reservations for traffic classes so that lossless and lossy traffic can coexist on the same link." ETS supplies reservations, PFC controls pauses, DCBx exchanges settings, and ECN signals congestion.

8. 8A fabric leaf must originate and terminate VXLAN tunnels to remote peers. Which function supplies those overlay tunnel endpoints?

   1. A.The underlay OSPF area
   2. B.The VXLAN tunnel endpointCorrect answer: B
   3. C.The EVPN route distinguisher
   4. D.The BGP route reflector

   Explanation: "A VXLAN Tunnel End Point (VTEP) is the function within leaf switches that handles the origination and termination of point-to-point tunnels forming an overlay network." The VTEP terminates the data-plane tunnels; the other choices concern routing or identification.

9. 9A CX 10000 is staged for ZTP using a wired network connection. Which switch port should be connected to the appropriate network?

   1. A.USB-A auxiliary port
   2. B.A QSFP28 data port
   3. C.RJ-45 out-of-band management portCorrect answer: C
   4. D.RJ-45 serial console port

   Explanation: "Connect the switch to the network using the RJ-45 out-of-band management port and power on the switch (or power off, then power on the switch)." The documented ZTP procedure uses the out-of-band management port.

10. 10An AOS-CX 10.13 design calls for a single L2 VNI to map an existing VLAN. What constraint applies when configuring that mapping?

    1. A.The VNI must have an EVPN-enabled default VRF
    2. B.The VNI must have two VLANs mapped to it
    3. C.The VNI must have symmetric routing disabledCorrect answer: C
    4. D.The VNI must have symmetric routing enabled

    Explanation: "Only one VLAN can be associated with a VNI and the VNI must have symmetric routing disabled." The L2 mapping requires symmetric routing disabled and allows one VLAN per VNI.
