Question 51

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?

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

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

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

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

Question 52

After having configured the edge switch uplink as requested your colleague says that they have failed to ping the core You ask your colleague to verify the connection is plugged in and the switch is powered on They confirm that both are correct You attempt to ping the core switch and confirm that the ping is failing.

Knowing the nature of this deployment, what commands might you use to troubleshoot this issued

Ping 10.11 1 - ping the core to attempt to verify connectivity Show trunk - to verify if the LAG interface was correctly added to the switch Show spanning tree - to check for spanning-tree blocked states Show port-access clients interface all - to view any port-access blocking states or failed authentication attempts on all interfaces Show run interface vlan20 - to double check the layer 3 svi configuration is correct for l_3 connectivity Show lldp neighors - to verify whether you are able to see the Core as an L2 neighbor to verify if the correct links are plugged in to the correct ports

diagnostic diag cable-diag 1/1/51 diag cable-diag 1/1/52 - to view diagnostic information for the physical link to get a status on any interruptions to Layer 1 connectivity, show ip route - to verify that the default gateway is present in the routing table show ip ospf - to check whether there is a layer 3 routing protocol enabled show ip dns - to view whether there is a valid dns source

Ping 10.1.1.1 - ping the core to attempt to verify connectivity show lacp agg - to verify which link aggregations are currently configured using which physical ports show lacp int - to verify the LACP status and whether any links are blocking in your topology show lldp neighors - to verify whether you are able to see the Core as an L2 neighbor to verify if the correct links are plugged in to the correct ports show run interface 1/1/51.1/1/52-to ensure the physical interfaces are no-shut and members of the lag show run interface lag 1 - to ensure the correct vlan trunking configuration is applied to the logical interface show run int vlan 20 - to ensure you have the L3 SVI no shut and configured in the correct subnet

Show run - to view the running configuration of the switch Show run | begin 20 'vlan 20' - to ensure VLAN 20 was correctly added to the database show run | begin 20 'interface vlan 20' - to view the L3 SVI configuration Show run interface 1/1/51.1/1/52 - to ensure the physical interfaces are no shut and were added as members of LAG 1 Show run int lag 1 - to verify LACP mode active was configured to eliminate LACP blocking states

Question 54

You are in a meeting with a customer where you are asked to explain how the network redundancy feature VRRP works. What is the correct statement for this feature?

VRRP uses BPDUs for messaging

VRRP uses multicast for messaging

VRRP uses unicast for messaging

VRRP uses broadcast for messaging

Question 55

Describe the functionality of ARP.

Clients do not have an ARP cache and always ask for the default gateway.

ARP maps MAC addresses to switch ports.

ARP maps layer-3 IP addresses to layer-2 MAC addresses.

ARP uses multicast to build the ARP table.

Question 57

What does a wireless client do first when its countdown timer reaches zero and it receives a Transmit Opportunity (TXOP)?

It immediately sends its Data Frames and receives an ACK from the AP.

It sends a CTS-to-self announcement to the ESP gateway.

It sends a CTS-to-self announcement to the AP and all other clients.

It sends a reassociation request frame to the AP and sends its Data Frames.

Question 58

What is an advantage of using Layer 2 MAC authentication?

MAC allow lists are easily maintained over time.

No setup is required on the client.

It matches user names to MAC address.

MAC identifiers are hard to spoof.

Question 59

The customer requires two Aruba CX 6200F 48G switches to be connected to each other with a distance of 80m/252ft between wiring closets. Switches need to have reservation for VSF expansion with ring topology in each cabinet.

What is a valid configuration for a redundant link-aggregation port configuration?

Ports 1/1/49 and 1/1/50 with SFP28 for LAG

Ports 1/1/47 and 1/1/48 for LAG

Ports 1/1/1 and 1/1/2 for LAG

Ports 1/1/51 and 1/1/52 with SFP+ for LAG
