HPE7-A04 Questions & Practice Test are Available On-Demand

NO.41 What is the maximum number of spines (when using 2 uplink ports for VSX) for CX 8325-48Y8C with Leaf- to-spine port speed 40 or 100 Gbps?

NO.42 In Aruba CX 8325 switches, what is true about port-groups?

Can have transceivers that operate at 100 Gbps

Each port-group can have different speed transceivers

All port-groups transceivers need to be of the same speed

Must have the same speed transceivers within a port-group

NO.43 Which technology uses LLDP TLVs to tell connected devices information such as the correct queue for PFC?

ETS

PFC

ECN

DCBx

NO.44 In ToR or Middle of Rack switch-Ports oriented to server ports:

The airflow of the switches should be back to front (BF)

The airflow of the switches should be front to back (FB)

It does not matter which direction is the airflow

It is recommended to use fanless Data Center Switches to overcome the heat generated

NO.45 ERPS (Ethernet Ring Protection Switching):

Is not supported on CX 6400 switch series

Is not supported on CX 8400 switch series

Prevents broadcast storms and implements fast-traffic switchover on a network where there are loops

Does not prevent broadcast storms but implements fast-traffic switchover on a network where there are loops

NO.46 Depending on a switch’s role in the topology, the demands on various tables differ. Several HPE Aruba CX switch models support different profiles, each of which optimizes the correct table for a switch with the corresponding role:

L3 Aggregates profile allocates more space to the support more overlay host entries table compared to leaf switches

L3 Aggregates profile allocates more space to the routing table compared to L3 core profile

L3 Aggregates profile allocates more space to the ARP/ND table compared to L3 core profile

L3 Aggregates profile allocates more space to the routing table compared to Spine switch

NO.47 What is true about the assumption documents

Must never be included in the solution proposal

Assumptions are so essentials that they need to always be included with every solution

Assumptions are only needed if the customer asks for it

Assumptions vary based on the project

NO.48 Which switch model is able to perform microsegmentation?

CX 10000

CX 8325

CX 8400

CX 8360

CX 6400

NO.49 You created a formal proposal and quote for a customer’s data center network refresh. What is some other support information that you should include? (Select two)

A list of IP addresses that you plan to configure on the switches

No need to include any of these as the proposal is not the place to educate the customer on them

HPE Aruba networking recommends including a block diagram with proposals

A list of VLANs that you plan to configure on the switches

NO.50 What resiliency technologies relate to Default Gateway redundancy requirement on CX switches?

VRRP

CVLAN

Transit VLAN

VSX Active Gateway

HSRP

NO.51 Which stacking technology is a dual control plane stacking that is supported by CX switches?

Back Plane Stacking

IRF

Front Plane Stacking

VSX

NO.52 Which switch model has the following specifications:
* 32 ports of 100GbE, 200GbE, or 400GbE
* 400 Gbps ports can be configured as 4x100GbE, 2x200GbE, or 1x400GbE

CX 8100 Switch Series

CX 8360v2 Switch Series

CX 8325 Switch Series

CX 9300 Switch Series

NO.53 What Fiber Optic standard supports up to 400 Gbps

No standard supports that bandwidth

QSFP+

QSFP28

QSFP-DD

NO.54 You want to implement distributed firewall policies that micro-segment VM-to-VM traffic, including within the VLAN and same host. The VMs should be able to send traffic on permitted TCP ports, but other traffic should be dropped (hosts are isolated). What are two requirements? (Select two.)

SVI 10 on the switch has IP local ARP proxy enabled on it

The VMware host is configured to implement a local firewall

VLAN 10 is converted to a PVLAN on the switch only. The VMs are placed in an isolatedVLAN

VLAN 10 is converted to a PVLAN on the switch and VMware hosts. The VMs are placed in an isolated VLAN

NO.55 In L3 spine and leaf design

Spanning Tree is always needed since Spine and Leaf is only there to improve performance

You need to use TRILL to prevent loops

You don’t need to use spanning tree for loop prevention

Since all Spine switches are connected to each other, EVPN is needed in this design

NO.56 You are involved in a 2-Tier L2 Data Center Design with the following details:
* CX 8325 100G Core Switches
* CX 10000 48-P 25G Access Switches
* 100G SR4 Optical connections between Core and Access
In this design, both the Core Layer and Access Layer consist of pairs of switches configured in VSX for HA.
Core Switches = VSX Pairs of CX 8325 32-port 100G switches (B-F airflow) Each pair uses:
* 2 x 100G QSFP28 1M DACs for ISL
* 1 x 100G QSFP28 1M DAC for Keepalive
* 2 x 100G QSFP28 SR4 Optic to each access switch Each Core switch has 13 available 100G QSFP28 interfaces.
What is the maximum number of racks supported by this design?

Solution can scale to 7 total racks using the same subscription rates.

Solution can scale to 14 total racks using the same subscription rates.

Solution can scale to 8 total racks using varying subscription rates.

Solution can scale to 16 total racks using the same subscription rates.

NO.57 How many SFP28 port-groups do Aruba 8325 CX switches have?

12 port-groups of 4 ports each

One port-group of 48 ports

4 port-groups of 8 ports each

4 port-groups of 12 ports

NO.58 You are designing an overlay solution for two Data Centers based on the Aruba CX platform. Each Data Center has two rooms and each room is its own fabric. There is a requirement for multicast traffic to be supported across all data center rooms and fabrics. What needs to be done?

Change the design to extend a single fabric across all rooms and both sites

Change the design to use one fabric per site

Use HPE Aruba CX switches’ selective split horizon feature

Establish a separate data center interconnect fabric for multicast traffic only

NO.59 What is true about the QSFP-DD MPO-12 eDR4 transceiver?

The maximum speed it can achieve is only 40 Gbps

The maximum distance it can run is 71-100 meters

The maximum speed it can achieve is 400 Gbps

It only works with MMF fiber type

NO.60 In a multi-AS underlay design

You must use eBGP for underlay routing within a leaf and spine topology

Either eBGP or iBGP for underlay routing within a leaf and spine topology will work
