Answer: A,D

NEW QUESTION # 26
A Network Operator is configuring VLANs on an HPE Aruba Networking CX switch to separate traffic for the Engineering (VLAN 10) and Sales (VLAN 20) departments. A user in the Engineering department connects their laptop to a port assigned to VLAN 20.
What will happen when the Engineering user's laptop sends a broadcast frame, such as an ARP request?

00:50:56:8d:1a:2b 1/1/1 Dynamic
00:50:56:8d:3c:4d 1/1/1 Dynamic
00:50:56:8d:5e:6f 1/1/2 Dynamic
How does a Layer 2 switch build this table?

• A. By downloading the table from the default gateway via ARP.

NEW QUESTION # 31
A retail store chain customer is replacing 1,479 AOS-S switches with HPE Aruba Networking CX
6000 switches. The customer is interested in utilizing ZTP to provision the new switches. Still, they are concerned about when the switch starts the ZTP process and whether the ZTP may change configurations on the switches already deployed. What would address this concern?

• A. If the ZTP operation detects that the switch configuration is different from the factory default configuration, the ZTP operation ends.
• B. If the ZTP operation detects that the switch has already been added to Aruba Networking Central, the ZTP operation ends.
• C. If the ZTP operation detects that ztp force-provisioning is set, software and configuration are automatically deployed, and the ZTP operation starts.
• D. If the ZTP operation detects that the DHCP option provided by the TFTP server already has the switch serial number assigned as a configuration file, the ZTP operation ends.

Answer: A

Explanation:
ZTP on HPE Aruba Networking CX switches runs only when the device is in its factory default state. If the switch detects that its configuration has already been modified from the factory default, the ZTP process stops, ensuring that ZTP does not overwrite or change configurations on switches that are already deployed.

NEW QUESTION # 32
A network technician wants to capture traffic from a user's PC connected to port 1/1/5 and send a copy of that traffic to their own laptop, connected to port 1/1/24, for analysis with a protocol analyzer like Wireshark.

• A. `ip helper-address`
• B. `loop-protect`
• C. `port-mirroring`
• D. `flow-control`

Answer: C

NEW QUESTION # 33
A Network Operator is troubleshooting a connectivity issue where a client (192.168.10.100) in VLAN 10 cannot ping a server (192.168.20.200) in VLAN 20. The operator checks the routing table on the core switch and confirms it has connected routes for both VLANs. The operator then checks the ARP table on the core switch.
The operator runs `show arp` on the core switch that acts as the gateway for both VLANs.
show arp vlan 20
IP Address MAC Address Port Type
-
192.168.20.1 00:d8:2f:1a:b3:c4 vlan20 Local
192.168.20.200 Incomplete Dynamic
Based on this output, what is the most direct cause of the communication failure?

• A. The client at 192.168.10.100 has an incorrect default gateway configured.
• B. The core switch's VLAN 20 interface is administratively down.
• C. The server at 192.168.20.200 is not responding to ARP requests from the core switch.
• D. The core switch does not have a route to the 192.168.20.0/24 network.

Answer: C

NEW QUESTION # 34
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 VSF on the CX 6200 and a lag for CX 6200 and 2530.
• B. Create a single domain VSF for CX 6200 and 2530.
• C. Create a lag on the 2530 to connect to both CX 6200 switches.
• D. Create VSF on the CX 6200 and use stacking with the 2530.

Answer: A

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.

NEW QUESTION # 35
Based on the example below:

What happens to the member status state if member 1 reboots?

• A. Member 2 becomes Standby
• B. Member 2 becomes Conductor
• C. Member 3 becomes Conductor
• D. Member 3 becomes Standby

Answer: B

Explanation:
The output shows member 1 is the Conductor and member 2 is the Standby. If the Conductor (member 1) reboots, the Standby takes over the control-plane role to maintain stack operation, so member 2 becomes the Conductor.

NEW QUESTION # 36
A Junior Network Engineer is comparing FTP and SFTP for managing switch configurations.
What are the key differences between FTP and SFTP? (Select all that apply.)

• A. SFTP runs over an SSH session, while FTP runs as its own distinct protocol.

• E. SFTP is an extension of FTP that adds a layer of SSL/TLS encryption.

Answer: A,C

• A. Cat5
• B. Cat5e
• C. Cat6
• D. Cat3

Answer: B
