Free Practice Questions for HP HPE7-A01 Exam

These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios thatare not possible or not relevant to the question.References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-

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.

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 loopprevention, load balancing, mobility, and scalability3.

The reason is that AOS 10.x does not support clustering gateways with different versions in the same cluster profile. A cluster profile defines the configuration settings for a group of gateways that are managed by Aruba Central.

According to the Aruba documentation2, “You can combine 7200 Series and 7000 Series gateways in the same cluster with a maximum size of four devices with reduced AP client capacity on 7000 Series gateways.”

According to the Aruba Documentation Portal1, the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.

This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second. Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port

These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator’s desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc. The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.

MPSK Local is a feature that can reduce the IT administration overhead associated with deploying devices that do not support 802.1X authentication while maintaining a secure environment. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require manual intervention by the installers or the MPSK gateway, or they do not provide unique pre-shared keys for devices.

Splitting a larger OSPF area into a number of smaller areas has several advantages for network scalability and performance. Some of these advantages are:

It increases stability by limiting the impact of topology changes within an area. When a link or router fails in an area, only routers within that area need to run the SPF algorithm and update their routing tables. Routers in other areas are not affected by the change and do not need to recalculate their routes.

It reduces processing overhead by reducing the size and frequency of link-state advertisements (LSAs). LSAs are packets that contain information about the network topology and are flooded within an area. By dividing a network into smaller areas, each area has fewer LSAs to generate, store, and process, which saves CPU and memory resources on routers.

It reduces bandwidth consumption by reducing the amount of routing information exchanged between areas. Routers that connect different areas, called area border routers (ABRs), summarize the routing information from one area into a single LSA and advertise it to another area. This reduces the number of LSAs that need to be transmitted across area boundaries and saves network bandwidth.

The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.

WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication.OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central1.

According to the Aruba documentConfiguring WLAN Settings for an SSID Profile, one of the steps to configure a WPA3 SSID is:

Select the Security Level from the drop-down list. The following options are available:

WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.

WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.

WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.

WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.

The other options are incorrect because:

A. WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company’s use case.

B. WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company’s use case.

D. WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company’s use case.
