NEW QUESTION # 23
You are helping an onsite network technician bring up an Aruba 9004 gateway with ZTP for a branch office The technician was to plug in any port for the ZTP process to start Thirty minutes after the gateway was plugged in new users started to complain they were no longer able to get to the internet. One user who reported the issue stated their IP address is 172.16 0.81 However, the branch office network is supposed to be on 10.231 81.0/24.
What should the technician do to alleviate the issue and get the ZTP process started correctly?
- A. Move the cable on the gateway from port G0/0V1 tc port GO 0.0
- B. Factory default and reboot the gateway to restart the process.
- C. Move the cable on the gateway to G0/0/1. and add the device's MAC and Serial number in Central
- D. Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach Aruba Activate
Answer: C
Explanation:
Explanation
This is the correct action to alleviate the issue and get the ZTP (Zero Touch Provisioning) process started correctly for an Aruba 9004 gateway. ZTP is a feature that allows an Aruba gateway to automatically download its configuration from Aruba Central without any manual intervention. To use ZTP, the gateway must be connected to a DHCP-enabled network and have Internet access. The gateway must also be added to Aruba Central using its MAC address and serial number. The default port for ZTP on an Aruba 9004 gateway is G0/0/1, which is labeled as Internet on the device. The other options are incorrect because they either do not use the correct port for ZTP or do not add the device to Aruba Central. References:

NEW QUESTION # 24
Your Aruba CX 6300 VSF stack has OSPF adjacency over SVI 10 with LAG 1 to a neighboring device The following configuration was created on the switch:
- A.
- B.
- C.
- D.
Answer: C
Explanation:
OSPF (Open Shortest Path First) is a routing protocol that uses link-state information to calculate the best path to each destination in the network. OSPF establishes adjacencies with neighboring routers to exchange routing information and maintain a consistent view of the network topology1.
To establish an OSPF adjacency, the routers need to have some common parameters, such as the area ID, the network type, the hello interval, the dead interval, and the authentication method2. The routers also need to have a matching subnet mask on the interface that connects them3.
In this case, the Aruba CX 6300 VSF stack has an SVI (Switched Virtual Interface) on VLAN 10 with an IP address of 10.1.1.1/24 and a LAG (Link Aggregation Group) on port 1/1/1 and port 2/1/1 that connects to a neighboring device. The SVI is configured with OSPF area 0 and network type broadcast. The LAG is configured with OSPF passive mode, which means that it will not send or receive OSPF hello packets.
The neighboring device has an interface with an IP address of 10.1.1.2/24 and a LAG on port 1/0/1 and port 2/0/1 that connects to the Aruba CX 6300 VSF stack. The interface is configured with OSPF area 0 and network type broadcast.
Since the Aruba CX 6300 VSF stack and the neighboring device have the same area ID, network type, subnet mask, and default hello and dead intervals on their interfaces, they will be able to establish an OSPF adjacency over SVI 10 with LAG 1. The OSPF passive mode on the LAG will not affect the adjacency, because it only applies to the LAG interface, not the SVI interface.
NEW QUESTION # 25
What is one advantage of using OCSP vs CRLs for certificate validation?
- A. reduces latency between the time a certificate is revoked and validation reflects this status
- B. less complex to implement
- C. higher availability for certificate validation
- D. supports longer certificate validity periods
Answer: A
Explanation:
Explanation
OCSP is a protocol that allows clients to query the CA or a trusted responder for the status of a specific certificate. OCSP requests and responses are smaller and faster than CRLs, and they can provide real-time information about the revocation status of a certificate12. CRLs are lists of all revoked certificates that are downloaded from the CA. CRLs can present issues, as they can become outdated and have to be downloaded frequently13. Therefore, OCSP reduces latency between the time a certificate is revoked and validation reflects this status. References: 1 https://sectigostore.com/blog/ocsp-vs-crl-whats-the-difference/ 2

NEW QUESTION # 26
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements. After the configuration was complete, it was noted that a user assigned with the auditors role did not have the appropriate level of access on the switch.
The user was not allowed to perform firmware upgrades and a privilege level of 15 was not assigned to their role. Which default management role should have been assigned for the user?
- A. administrators
- B. sysops
- C. sysadmin
- D. config
Answer: B
Explanation:
The correct answer is B. sysops.
The sysops user role is a predefined role that allows users to perform system operations on the switch, such as backup, restore, upgrade, or reboot. The sysops user role also has access to the PUT and POST methods for REST API, which can be used to modify the switch configuration. The sysops user role has a privilege level of 15, which is the highest level of access on the switch1.
The other options are incorrect because:
A) sysadmin: The sysadmin user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The sysadmin user role does not have access to the REST API methods, and cannot perform firmware upgrades1.
C) administrators: The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires1.
D) config: The config user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The config user role does not have access to the REST API methods, and cannot perform firmware upgrades1.
NEW QUESTION # 27
you need to have different routing-table requirements With Aruba CX 6300 VSF configuration.
Assuming the correct layer-2 VLAN already exists, how would you create a new SVI for a separate routing table?
- A. create a new VLAN, and attach the VRF to it.
- B. Create a new SVI and use attach command.
- C. Create a new VLAN. and attach the routing table to it
- D. Create a new routing table, and attach VLANS to it
Answer: B
Explanation:
Explanation
The correct answer is C. Create a new SVI and use attach command.
To create a new SVI for a separate routing table, you need to use the attach command to associate the SVI with a VRF (Virtual Routing and Forwarding) instance. A VRF is a logical entity that allows multiple routing tables to coexist on the same switch. Each VRF has its own set of interfaces, routing protocols, and routes that are isolated from other VRFs.
According to the AOS-CX Virtual Switching Framework (VSF) Guide1, one of the steps to configure VRF-aware VSF is:
Configure the VRFs on each member switch and assign the SVIs to the respective VRFs using the attach command. For example:
switch(config)# vrf red
switch(config-vrf)# exit
switch(config)# interface vlan 10
switch(config-if-vlan)# ip address 10.1.1.1/24
switch(config-if-vlan)# attach vrf red
The above commands create a VRF named red and assign VLAN 10 SVI to it. The SVI has an IP address of
10.1.1.1/24.
The other options are incorrect because:
A: You cannot attach a VRF to a VLAN directly. You need to create an SVI for the VLAN and then attach the VRF to the SVI.
B: You cannot create a new routing table manually. You need to create a VRF and then use routing protocols or static routes to populate the routing table for the VRF.
D: You cannot attach a routing table to a VLAN directly. You need to create an SVI for the VLAN and then attach a VRF that has a routing table associated with it.
NEW QUESTION # 28
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements After the configuration was complete, it was noted that a user assigned with the administrators role did not have the appropriate level of access on the switch.
The user was not limited to viewing nonsensitive configuration information and a level of 1 was not assigned to their role Which default management role should have been assigned for the user?
- A. operators
- B. helpdesk
- C. sysadmin
- D. config
Answer: A
Explanation:
Explanation
The default management role that should have been assigned for the user is B. operators.
The operators user role is a predefined role that allows users to view nonsensitive configuration information on the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The operators user role has a privilege level of 1, which is the lowest level of access on the switch1.
The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires1.
NEW QUESTION # 29
Which statements are true regarding a VXLAN implementation on Aruba Switches? (Select two.)
- A. MTU size must be increased beyond the default
- B. VNIs encapsulate and decapsulate VXLAN traffic
- C. VTEPs encapsulate and decapsulate VXLAN traffic
- D. All Aruba CX switches support VXLAN.
- E. They are only available for datacenter switches (CX 8k, 9k,10k)
Answer: A,B
Explanation:
Explanation
Option A: MTU size must be increased beyond the default
This is because option A shows how to configure the MTU size for VXLAN tunnels on Aruba switches using the interface command and the vxlan command. The MTU size must be increased beyond the default value of
1500 bytes to accommodate the VXLAN header and payload2.
Therefore, option A is true regarding a VXLAN implementation on Aruba switches.
Option B: VNIs encapsulate and decapsulate VXLAN traffic
This is also true regarding a VXLAN implementation on Aruba switches. VNIs are used to encapsulate and decapsulate VXLAN traffic between two devices, such as a switch and a server. VNIs are also used to map VXLAN tunnels to overlay networks3.
Therefore, option B is also true regarding a VXLAN implementation on Aruba switches.
VXLAN is a Layer 2 encapsulation technology that substitutes the usage of VLAN numbers to label Ethernet broadcast domains with VXLAN numbers. VXLAN supports 224 Ethernet broadcast domains or VXLAN numbers. A VXLAN number ID is referred to as VNI. There is a one-to-one relationship between an Ethernet broadcast domain and a VNI. A single Ethernet broadcast domain can't have more than one VNI.

- A. int 1/1/1-1/1/28. loop-guard
- B. int 1/1/1-1/1/28. loop-protect
- C. int 1/1/1-1/1/24. loop-guard
- D. int 1/1/1-1/1/24, loop-protect
Answer: D
Explanation:
Explanation
The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.
NEW QUESTION # 32
Refer to the image.
Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7
- A. The AP is using a directional antenna.
- B. The AP is configured in Mesh mode
- C. The AP is a remote access point.
- D. The AP is an outdoor access point.
Answer: A
Explanation:
Explanation
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna.
A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

NEW QUESTION # 33
A customer has a large number of food-producing machines
* All machines are connected via Aruba CX6200 switches in VLANs 100.110. and 120
* Several external technicians are maintaining this special equipment
What are the correct commands to ensure that no rogue DHCP server will impact the network?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Explanation
Option A shows the correct commands to ensure that no rogue DHCP server will impact the network. The commands include the following steps:
* Enable DHCP snooping on the switch. DHCP snooping is a feature that prevents rogue DHCP servers from offering IP addresses to clients by filtering DHCP messages based on trusted and untrusted ports1.
* Configure VLANs 100, 110, and 120 as DHCP snooping VLANs. This means that DHCP snooping will be applied to these VLANs and any untrusted DHCP messages received on these VLANs will be dropped1.
* Configure LAG 1 as a trusted port for DHCP snooping. This means that any DHCP messages received on LAG 1 will be allowed and not filtered by DHCP snooping. LAG 1 is assumed to be connected to a legitimate DHCP server or a router that relays DHCP requests to a legitimate DHCP server1.
Option B is incorrect because it does not enable DHCP snooping on the switch or configure VLANs 100, 110, and 120 as DHCP snooping VLANs. Option C is incorrect because it does not configure LAG 1 as a trusted port for DHCP snooping. Option D is incorrect because it does not enable DHCP snooping on the switch or configure LAG 1 as a trusted port for DHCP snooping. References: 1

NEW QUESTION # 34
A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working to a remote site connected via layer-3 All legacy devices are connected to a dedicated Aruba CX 6200 switch at each site.
What technology on the Aruba CX 6200 could be used to meet this requirement?
- A. Ethernet over IP (EolP)
- B. Generic Routing Encapsulation (GRE)
- C. Inclusive Multicast Ethernet Tag (IMET)
- D. Static VXLAN
Answer: C
Explanation:
VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches.

NEW QUESTION # 35
What are the requirements to ensure that WMM is working effectively'? (Select two)
- A. The AP needs to be connected via a tagged VLAN to the wired port
- B. The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.
- C. All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
- D. The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
- E. The Aruba AOS10 APs installed have to be converted to controlled mode
Answer: B,D
Explanation:
Explanation
These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work. References:

NEW QUESTION # 36
You are configuring Policy Based Routing (PBR) for a subnet that will be used to test a new default route for your network Traffic originating from 10.2.250.0/24 should use a new default route to 10.1.1.253. Other non-default routes for this subnet should not be affected by this change.
What are two parts of the solution for these requirements? (Select two.)
- A.
- B.
- C.
- D.
- E.
Answer: A,D
Explanation:
Explanation
Two parts of the solution for these requirements are Option C and Option E.
Option C is a part of the solution because it defines a policy-based routing action list named route_test, which specifies the next hop IP address as 10.1.1.253 for the matching traffic. This is the new default route that the user wants to use for the subnet 10.2.250.0/24. The interface null parameter indicates that the traffic will be routed to the next hop without using a specific interface1.
Option E is a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 250, which has an IP address of 10.2.250.1/24. This is the subnet that the user wants to test the new default route for. The apply policy command enables policy-based routing on the interface and associates it with the action list2.
Option A is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify the next hop IP address as 10.1.1.253, which is the new default route that the user wants to use. Instead, it specifies a next hop IP address of 10.1.1.254, which is different from the requirement.
Option B is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify any next hop IP address at all, which is necessary for policy-based routing to work. Instead, it specifies an interface null parameter without any IP address, which is invalid.
Option D is not a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 200, which has an IP address of 10.2.200.1/24. This is not the subnet that the user wants to test the new default route for, but a different subnet that should not be affected by this change.
NEW QUESTION # 37
Which statements are true about VSX LAG? (Select two.)
- A. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
- B. The total number of configured links may not exceed 8 for the pair or 4 per switch
- C. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
- D. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.
- E. Outgoing traffic is preferentially switched to local members of the LAG.
Answer: B,E
Explanation:
Explanation
The correct answers are A and D.
According to the web search results, VSX LAG is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices1. VSX LAGs span both aggregation switches and appear as one device to partner downstream or upstream devices or both when forming a LAG with the VSX pair2.
One of the statements that is true about VSX LAG is that the total number of configured links may not exceed
8 for the pair or 4 per switch1. This means that a VSX LAG across a downstream switch can have at most a total of eight member links, and a switch can have a maximum of four member links. When creating a VSX LAG, it is recommended to select an equal number of member links in each segment for load balancing1.
Another statement that is true about VSX LAG is that outgoing traffic is preferentially switched to local members of the LAG2. This means that when active forwarding and active gateway are enabled, north-south and south-north traffic bypasses the ISL link and uses the local ports on the switch. This optimizes the traffic path and reduces the load on the ISL link2.
The other statements are false or not relevant for VSX LAG. Outgoing traffic is not switched to a port based on a hashing algorithm, which may be either switch in the pair. This is a characteristic of MLAG (Multi-Chassis Link Aggregation), which is a different feature from VSX LAG. LAG traffic is not passed over VSX ISL links only while upgrading firmware on the switch pair. This is a scenario that may occur when performing hitless upgrades, which is a feature that allows software updates without impacting network availability. The number of VSX lags that can be configured on all 83xx and 84xx model switches is not 255, but depends on the switch model and firmware version. For example, the AOS-CX 10.04 supports up to 64 VSX lags for 8320 switches and up to 128 VSX lags for 8325 and 8400 switches.
