Does this correctly describe routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN?
Solution: IMET routes advertise the MAC addresses that the VTEP has learned locally in a VXLAN.
- A. No
- B. Yes
Answer: A
Explanation:
IMET routes advertise the MAC addresses that the VTEP has learned locally in a VXLAN is not a correct description of routing information advertised by a VXLAN Tunnel Endpoint (VTEP) that uses EVPN. IMET routes are one of the types of routes that EVPN uses to advertise multicast information for VXLAN networks. IMET routes advertise the IP addresses of VTEPs that can join multicast groups for VXLAN segments.

NEW QUESTION # 66
Is this a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching Extension (VSX) fabric?
Solution: You are not concerned about split brain Issues in your environment, so you want the secondary member to keep its links up if the ISL falls.
- A. No
- B. Yes
Answer: B
Explanation:
You are not concerned about split brain issues in your environment, so you want the secondary member to keep its links up if the ISL fails is a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching Extension (VSX) fabric. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The ISL is the inter-switch link that connects two VSX nodes and carries data traffic. The split-recovery mode is a feature that prevents split-brain scenarios when both VSX nodes lose connectivity with each other but remain up. When split-recovery mode is disabled, if the ISL fails but both VSX nodes remain up,
NEW QUESTION # 67
Is this something that NetEdit 2.0 does after it discovers a switch?
Solution: It collects Information about the switch hardware.
- A. No
- B. Yes
Answer: B
Explanation:
It collects information about the switch hardware is something that NetEdit 2.0 does after it discovers a switch. NetEdit 2.0 is a tool that provides configuration management and validation for ArubaOS-CX and ArubaOS-Switch devices. NetEdit 2.0 can discover switches using various methods such as IP range scan, LLDP scan, CSV import, etc. After NetEdit 2.0 discovers a switch, it collects information about the switch hardware such as model number, serial number, MAC address, firmware version, etc.
NEW QUESTION # 68
Refer to the exhibit. Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. Does this correctly explain how to control how core-to-access traffic Is forwarded?
Solution: To force the router to use both links, ensure that active gateway is enabled on LAG 100 on both Switch-1 and Switch-2.
- A. No
- B. Yes
Answer: A
Explanation:
The exhibit shows a network topology where Switch-1 and Switch-2 are part of a Virtual Switching Extension (VSX) fabric, and the router runs OSPF on LAG 100, which is a Layer 3 LAG. The question asks how to control how core-to-access traffic is forwarded, which means how the router chooses between the two links to Switch-1 and Switch-2. To force the router to use both links, ensuring that active gateway is enabled on LAG 100 on both Switch-1 and Switch-2 is not the correct solution. Active gateway is a feature that allows both VSX members to act as the default gateway for downstream devices, using a common virtual MAC address. Active gateway does not affect how upstream devices, such as the router, forward traffic to the VSX members. To force the router to use both links, the correct solution is to configure equal-cost multi-path (ECMP) in OSPF on the router. ECMP is a feature that allows a router to load balance traffic across multiple paths with the same cost. ECMP can be configured using the maximum-paths command and specifying how many equal-cost paths the router should use2. Therefore, this does not correctly explain how to control how core-to-access traffic is forwarded.
NEW QUESTION # 69
Is this a best practice when positioning ArubaOS-CX switches in data center networks?
Solution: Deploy Aruba CX 6300 switches as data center spine switches.
- A. No
- B. Yes
Answer: A
Explanation:
Deploy Aruba CX 6300 switches as data center spine switches is not a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 6300 switches are designed for data center leaf roles, and they provide high density, low latency, and advanced features such as VSX and EVPN. The Aruba CX 83xx switches are more suitable for data center spine roles, and they provide high performance, scalability, and resiliency1.

Solution: Ring 1, instance 1:
control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2:
control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220
- A. No
- B. Yes
Answer: A
Explanation:
Ring 1, instance 1: control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2: control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220 is not a valid design for the control and protected VLANs on the VSX fabric 1 switches for an Ethernet Ring Protection Switching (ERPS) solution. The control VLANs must be unique for each ring instance and must not overlap with any protected VLANs. In this design, the control VLAN 1000 is used for both ring 1 instance 1 and ring 2 instance 1, which can cause conflicts and errors. Also, the protected VLANs 181-220 are used for both ring instances on ring 2, which can cause loops and traffic duplication2.
NEW QUESTION # 74
Refer to the exhibits.
Is this how the switch-1 handles the traffic?
Solution: A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN10. except the incoming interface. It replicates the broadcast, encapsulates each broadcast with VXLAN. and sends the VXLAN traffic to 192.168.1.2 and 192.168.1.3.
- A. No
- B. Yes
Answer: B
Explanation:
A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN10, except the incoming interface. It replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to 192.168.1.2 and 192.168.1.3 is a correct explanation of how the switch handles the traffic. Switch-1, Switch-2, and Switch-3 are ArubaOS-CX switches that use VXLAN and EVPN to provide Layer 2 extension over Layer 3 networks. VXLAN is a feature that uses UDP encapsulation to tunnel Layer 2 frames over Layer 3 networks using VNIs. EVPN is a feature that uses BGP to advertise multicast information for VXLAN networks using IMET routes. Switch-1 receives a broadcast in VLAN 10, which belongs to VNI 5010. Switch-1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface, as per normal Layer 2 switching behavior. Switch-1 replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to both 192.168.1.2 and 192.168.1.3, which are Switch-3's and Switch-2's loopback interfaces respectively.
NEW QUESTION # 75
Is this statement about ARP and ND Suppression true?
Solution: Both ARP-Suppression and ND-Suppression are disabled by default.
- A. No
- B. Yes
Answer: A
Explanation:
Both ARP-Suppression and ND-Suppression are disabled by default is not a true statement about ARP and ND Suppression. ARP-Suppression is enabled by default on ArubaOS-CX switches, while ND-Suppression is disabled by default. ARP-Suppression and ND-Suppression are features that reduce broadcast traffic on VXLAN networks by using a local ARP/ND cache on each switch instead of flooding ARP/ND requests to all VXLAN tunnel endpoints (VTEPs).
NEW QUESTION # 76
Is this a way that a data center technology can help meet requirements for multi-tenancy?
Solution: Virtual Extensible LAN (VXLAN) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network.
- A. No
- B. Yes
Answer: A
Explanation:
Virtual Extensible LAN (VXLAN) enables multiple isolated Layer 3 domains, each with its own routing table, to share a physical network is not a way that a data center technology can help meet requirements for multi-tenancy. Multi-tenancy is the ability to provide logical separation and isolation of network resources for different tenants or customers on a shared physical infrastructure. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation. VXLAN does not enable multiple isolated Layer 3 domains, but rather multiple isolated Layer 2 domains, each with its own VNI.
NEW QUESTION # 77
Does this correctly describe the ArubaOS-CX architecture?
Solution: The AtubaOS-CX software is based on the ArubaOS-Switch software and adds data center features.
- A. No
- B. Yes
Answer: A
Explanation:
The ArubaOS-CX software is based on the ArubaOS-Switch software and adds data center features is not a correct description of the ArubaOS-CX architecture. The ArubaOS-CX software is a new operating system that is designed for data center and campus networks. It is not based on the ArubaOS-Switch software, which is used for legacy campus switches. The ArubaOS-CX software provides advanced features such as VSX, EVPN, NAE, REST APIs, etc.
NEW QUESTION # 78
Is this a way that Virtual Switching Extension (VSX) differs from Virtual Switching Framework (VSF)?
Solution: VSX is recommended for the access layer of data centers and campuses while VSF is recommended for the core.
- A. No
- B. Yes
Answer: A
Explanation:
VSX is not recommended for the access layer of data centers and campuses while VSF is recommended for the core. VSX and VSF are both high availability solutions that provide redundancy and load balancing across a pair of switches. However, VSX is recommended for the core and aggregation layers of data centers and campuses, while VSF is recommended for the access layer of campuses. The statement is false because it reverses the recommended roles of VSX and VSF.
NEW QUESTION # 79
Is this part of the process for using NetEdit to update firmware on ArubaOS-CX switches?
Solution: Upload firmware images to the NetEdit firmware repository.
- A. No
- B. Yes
Answer: B
Explanation:
Uploading firmware images to the NetEdit firmware repository is part of the process for using NetEdit to update firmware on ArubaOS-CX switches1. NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface1. It also provides a firmware repository where you can store firmware images for different switch models and versions1. You can use NetEdit to upload firmware images to the repository and then deploy them to the switches1.
NEW QUESTION # 80

NEW QUESTION # 81
Refer to the exhibit.
Switch-1, Switch-2, and the router run OSPF on LAG 100, which is a Layer 3 LAG. Does this correctly explain how to control how core-to-access traffic Is forwarded?
Solution: To reduce the amount of traffic sent over the ISI between Switch-1 and Swltch-2. enable active forwarding on LAG 100 on both Switch-1 and Switch-2.
- A. No
- B. Yes
Answer: B
NEW QUESTION # 82
A customer's servers use ISCSI, and they send data and storage traffic on the same pair of I OGbE links. Is this a best practice for supporting the ISCSI requirements?
Solution: Use Virtual Routing and Forwarding (VRF) to tunnel iSCSI traffic through the network spine on the same links that data traffic uses.
- A. No
- B. Yes
Answer: A
Explanation:
ISCSI is a protocol that allows storage devices to communicate over IP networks. ISCSI traffic has different requirements than data traffic, such as low latency, high throughput, and reliability.
Therefore, it is not a best practice to send data and storage traffic on the same pair of 10GbE links, as this can cause congestion and performance degradation. It is also not a best practice to use Virtual Routing and Forwarding (VRF) to tunnel ISCSI traffic through the network spine on the same links that data traffic uses. VRF is a technology that creates multiple isolated Layer 3 domains on a physical network, each with its own routing table. VRF does not provide any benefits for ISCSI traffic, as it does not guarantee bandwidth, priority, or quality of service. VRF also adds overhead and complexity to the network configuration. Therefore, this is not a valid way to support the ISCSI requirements.
