NEW QUESTION # 18
A Solutions Architect is diagnosing a network issue where a specific server is unreachable. The architect uses `traceroute` and the output stops at a particular router, which is the last responsive hop. The architect now wants to verify the complete routing table on that specific router to understand why it is not forwarding the traffic correctly.
1 10.1.1.1 (10.1.1.1) 1.123 ms 1.122 ms 1.121 ms
2 10.10.1.2 (10.10.1.2) 5.432 ms 5.433 ms 5.432 ms
3 * * *
4 * * *
The last responsive hop is 10.10.1.2.
Which command would the architect use on the router at 10.10.1.2 to validate its entire Layer 3 forwarding table?
- A. `show mac-address-table`
- B. `show lldp neighbor-info`
- C. `show interface brief`
- D. `show ip route`
Answer: D
NEW QUESTION # 19
A Network Operator is troubleshooting a user's report of being unable to access a specific external website, `corp.example.com`. The operator can successfully ping the website's IP address (198.51.100.10) from the user's gateway switch, confirming basic Layer 3 reachability.
The operator now suspects a DNS resolution issue.
The operator needs a command that will:
1. Use the switch's configured DNS servers.
2. Attempt to resolve the hostname `corp.example.com` to an IP address.
3. Display the resulting IP address if successful.
Which of the following commands is the correct tool to perform this DNS validation task directly from the switch?
- A. `show hosts`
- B. `ping corp.example.com`
- C. `traceroute corp.example.com`
- D. `show dns client`
Answer: B
NEW QUESTION # 20
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?
- A. The switch will drop the frame because the user is in the wrong VLAN.
- B. The frame will be received by all devices in both VLAN 10 and VLAN 20.
- C. The frame will only be received by other devices in VLAN 20.
- D. The frame will be forwarded to the default gateway for routing to VLAN 10.
Answer: C
NEW QUESTION # 21
Which of these is a configurable VLAN on a CX switch?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
VLAN IDs on CX switches follow the IEEE 802.1Q standard, which allows configurable VLAN IDs in the range from 1 to 4094. The value 3748 falls within this valid range.

- C. Private VLANs
- D. VLAN Tagging
Answer: B
NEW QUESTION # 26
A Solutions Architect is designing a new, highly resilient access layer using a stack of HPE Aruba Networking CX 6300 switches. To simplify management and provide seamless redundancy, the architect has decided to use the Virtual Switching Framework (VSF) to stack two switches together.
* Switch 1 (Future Commander): The architect is connected to this switch via the console.
* Switch 2 (Future Standby): Is in a factory default state.
* VSF Links: The switches will be connected in a ring topology using the dedicated VSF ports 1 and 2 on the rear of the switches.
* VSF Domain ID: 10
Which of the following command sets, when executed on Switch 1, correctly initiates the VSF formation process?
- A. switch(config)# vsf member 1 priority 200
switch(config)# vsf member 2 priority 100
switch(config)# vsf enable domain 10 - B. switch(config)# vsf enable domain 10
switch(config)# vsf renumber-to 1 - C. switch(config)# vsf member 1 link 1 1/1/49
switch(config)# vsf member 1 link 2 1/1/50
switch(config)# vsf enable domain 10 - D. switch(config)# vsf link 1 interface 1/1
switch(config)# vsf link 2 interface 1/2
switch(config)# vsf enable domain 10
Answer: C
NEW QUESTION # 27
When explaining the HPE Aruba Networking Virtual Switching features, which statement about VSX is true?
- A. The management plane is shared.
- B. The configuration can vary between two and ten members.
- C. The switch control plane operates independently.
- D. The switch member ID changes on members other than the primary.
Answer: C
Explanation:
In a VSX pair, each switch maintains its own independent control plane. This design avoids a single point of failure and allows both switches to continue operating and forwarding traffic even if the peer becomes unavailable.
NEW QUESTION # 28
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 # 29
A Network Technician is configuring a new AOS-CX switch to enable it to route traffic between different VLANs. The switch has several VLANs with IP addresses (SVIs) already configured.
Which single command must be enabled in the global configuration context to activate the switch's Layer 3 routing capabilities?
- A. `enable`
- B. `ip routing`
- C. `router ospf 1`

NEW QUESTION # 30
Which attributes are true about UDP? (Choose two.)
- A. supports retransmission
- B. connectionless
- C. used for latency-sensitive traffic
- D. requires an established connection
- E. uses sequence numbers
Answer: B,C
Explanation:
UDP is a connectionless protocol, meaning it does not establish or maintain a session before sending data. It is commonly used for latency-sensitive traffic where speed is prioritized over reliability, such as voice and video applications.
NEW QUESTION # 31
A CX 6200 VSF stack is the L3 gateway for a mid-sized company. Users are divided into three different subnets on VLANs: 100, 200, and 300. VLAN 50 contains a management network for access points, switches, and DHCP servers. How do the Access Points get an IP address using DHCP?
- A. As a response to the anycast DHCP query.
- B. As a response to the broadcast DHCP query.
- C. As a response to the multicast DHCP query.
- D. As a response to the unicast DHCP query
Answer: B
Explanation:
DHCP clients, such as access points, initially do not know the IP address of the DHCP server.
They obtain an IP address by sending a broadcast DHCP discovery message on the local VLAN, to which the DHCP server (or relay) responds.
NEW QUESTION # 32
A Network Operator wants to ensure that critical traffic, like VoIP, experiences minimal delay as it exits a congested switch port.
Which QoS mechanism is responsible for sorting packets into different buffers and determining the order in which they are transmitted?
- A. Classification
- B. Policing
- C. Queuing
- D. Marking
Answer: C
NEW QUESTION # 33
How does AOS-CX determine the Router Identifier (RID) if it is not manually specified?

- C. It uses the IP address of the loopback interface with the highest IP address.
- D. It uses the IP address of the non-loopback interface with the highest IP address.
- E. It uses the IP address of the loopback interface with the lowest IP address.
Answer: C
NEW QUESTION # 34
