NEW QUESTION # 42
How can an administrator verify that an Aruba switch is forwarding traffic correctly?

• A. show interfaces
• B. show running-config
• C. show vlan
• D. show ip route

Answer: A

Explanation:
The show interfaces command is the most appropriate tool to verify if an Aruba switch is forwarding traffic correctly. It provides detailed statistics about each interface, including:
Interface status (whether the port is up or down)
Traffic statistics (input/output bytes, packets, errors, discards, etc.) Link status (e.g., whether the link is physically operational) Traffic flow (whether data is being transmitted or received on the port) This allows the administrator to check if traffic is being forwarded on the interfaces and identify any issues, such as errors or drops, that might indicate a problem with forwarding traffic.

NEW QUESTION # 44
A Solutions Architect is designing a routing solution for a branch office. The office has a core switch that needs to be configured to route between the local user VLAN (VLAN 10) and a server VLAN (VLAN
20). Additionally, all traffic destined for the internet must be forwarded to a primary firewall at
10.255.255.1. For redundancy, a secondary, floating static route should be configured to forward traffic to a backup firewall at 10.255.255.5 only if the primary path fails.
Initial State:
* The switch is in its factory default state, connected via the console.
* VLANs 10 and 20 are already created.
Required Configuration:
* Enable IP routing on the switch.
* Configure an SVI for VLAN 10 with IP address 192.168.10.1/24.
* Configure an SVI for VLAN 20 with IP address 192.168.20.1/24.
* Configure the primary default route to 10.255.255.1.
* Configure the backup default route to 10.255.255.5 with an administrative distance of 10.
Which configuration set correctly implements this routing design?

• A. ip routing
  interface vlan 10
  ip address 192.168.10.1/24
  interface vlan 20
  ip address 192.168.20.1/24
  ip route 0.0.0.0/0 10.255.255.1
  ip route 0.0.0.0/0 10.255.255.5 10
• B. ip routing
  interface vlan 10
  ip address 192.168.10.1/24
  interface vlan 20
  ip address 192.168.20.1/24
  ip route 0.0.0.0/0 10.255.255.1 preference 1

NEW QUESTION # 47
A customer is about to connect a new CX 6200 switch using ports 1/1/47 and 1/1/48 to an existing 5406R in a VSF configuration. The VSF is already configured with the following settings:
trunk 1/A24, 2/A24 trk2
trk2
vlan tagged 100,200,300
vlan untagged 50
What needs to be configured on the new CX 6200 switch?

• A. !
  interface lag 27
  lacp mode static
  vlan trunk allowed 50,100,200,300
  vlan trunk native tagged 50
  !
• B. !
  interface lag 27
  vlan trunk allowed 50,100,200,300
  vlan trunk native 50
  !
• C. !
  interface lag 27
  lacp mode static
  vlan trunk allowed 50,100,200,300
  vlan trunk native untagged 50
  !
• D. !
  interface lag 27
  vlan trunk allowed 100,200,300
  vlan trunk native 50
  !

Answer: B

Explanation:
The existing 5406R uses a trunk that carries VLANs 100/200/300 tagged and VLAN 50 untagged.
On the CX 6200, the corresponding LAG must be configured as a VLAN trunk with VLAN 50 as the native (untagged) VLAN and with VLANs 50, 100, 200, and 300 permitted on the trunk so the untagged VLAN and the tagged VLANs are all carried across the link.

NEW QUESTION # 48
A network is configured with two 2930F switches as the aggregation layer. Each 2930F switch has ten connections. The network has twenty 2530 access switches connected to both aggregation switches with 1Gb RJ45. Your task is to replace the aggregation switches with CX
6200 models. In this scenario, which configuration would provide redundancy using two ports on the access switches to the aggregation layer?

• A. Create a lag on the 2530 to connect to both CX 6200 switches.
• B. Create VSF on the CX 6200 and use stacking with the 2530.
• C. Create VSF on the CX 6200 and a lag for CX 6200 and 2530.
• D. Create a single domain VSF for CX 6200 and 2530.

Answer: C

Explanation:
By forming a VSF stack with the two CX 6200 switches, they operate as a single logical switch.
This allows each 2530 access switch to build one LACP LAG using two uplink ports -- one to each CX 6200 member -- while still being treated as a single aggregated connection, providing link and switch redundancy.
