NEW QUESTION # 123
For the Aruba CX 6400 switch, what does virtual output queueing (VOQ) implement that is different from most typical campus switches?

A. per port ASICs
B. large ingress packet buffers
C. VSX
D. large egress packet buffers

Answer: B

Explanation:
Explanation
The Aruba CX 6400 switch is a modular switch that supports high-performance and high-density Ethernet switching for campus and data center networks. One of the features that distinguishes the Aruba CX 6400 switch from most typical campus switches is virtual output queueing (VOQ). VOQ is a technique that implements large ingress packet buffers on each port to prevent head-of-line blocking and packet loss due to congestion2. VOQ allows each port to have multiple queues for different output ports and prioritize packets based on their destination and QoS class2. VOQ enables the Aruba CX 6400 switch to achieve high throughput and low latency for various traffic types and scenarios. References: 2

NEW QUESTION # 124
Refer to Exhibit:

With Access-1, What needs to be identically configured With MSTP to load-balance VLANS?

A. Spanning-tree instance vlan mapppjng
B. Spanning-tree root-guard setting
C. Spanning-tree bpdu-guard setting
D. spanning-tree Cist mapping

Answer: A

Explanation:
The correct answer is B. Spanning-tree instance VLAN mapping.
To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.
According to the Cisco document Understand the Multiple Spanning Tree Protocol (802.1s), one of the steps to configure MST is:
Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500. These statements are true for this configuration:
Switch D1(config)#spanning-tree mst configuration
Switch D1(config-mst)#instance 1 vlan 501-1000
Switch D1(config-mst)#exit
Switch D1(config)#spanning-tree mst 1 priority 0
Switch D2(config)#spanning-tree mst configuration
Switch D2(config-mst)#instance 2 vlan 1-500
Switch D2(config-mst)#exit
Switch D2(config)#spanning-tree mst 2 priority 0
The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.
The other options are incorrect because:
A) Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an unauthorized device. It does not affect load balancing with MSTP.
C) Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches.
D) Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.

NEW QUESTION # 125
Which method is used to onboard a new UXI in an existing environment with 802.1X authentication? (The sensor has no cellular connection)

A. Use the CLI via the serial cable and adjust the initial configuration.
B. Connect the new UXI from an already installed one and adjust the initial configuration.
C. Use the UXI app on your smartphone and connect the UXI via Bluetooth
D. Use the Aruba installer app on your smartphone to scan the barcode

Answer: C

Explanation:
To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc. The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.

NEW QUESTION # 126
A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working across the campus which is connected via layer-3. The legacy devices are connected to Aruba CX 6300 switches throughout the campus.
Which technology minimizes flooding so the legacy application can work efficiently?

A. EVPN-VXLAN
B. Ethernet over IP (EolP)
C. Generic Routing Encapsulation (GRE)
D. Static VXLAN

Answer: A

Explanation:
EVPN-VXLAN is a technology that allows layer-2 communication across layer-3 networks by using Ethernet VPN (EVPN) as a control plane and Virtual Extensible LAN (VXLAN) as a data plane3. EVPN- VXLAN can be used to support legacy applications that communicate at layer-2 across different campuses or data centers that are connected via layer-3. EVPN-VXLAN minimizes flooding by using BGP to distribute MAC addresses and IP addresses of hosts across different VXLAN segments3. EVPN- VXLAN also provides benefits such as loop prevention, load balancing, mobility, and scalability3.

NEW QUESTION # 127
By default, Best Effort is higher priority than which priority traffic type?

A. Background
B. Internet Control
C. All queues
D. Network Control

Answer: A

Explanation:
This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency). A typical example would be peer-to-peer and email applications2. Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network3.
Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.
