Improving the performance of an application to make users happy

Improve oversubscription ratio to 3:1 Certainly! Here are the questions formatted as requested:

When collecting information about the Power in your Data Center design you need to take into account (Select two)

The type of the voltage DC or AC

The fiber strands that are needed to support the TOR switches

The type of the voltage DC or AC

What is the transit VLAN that runs between VSX members?

It is a routed VLAN allowed in the ISL to ensure that the two switches within a VSX pair can learn routes from one another, in potential failover situations

Must not be assigned IP addresses on any switch.

It is used as a keepAlive mechanism

It is a routed VLAN allowed in the ISL to ensure that the two switches within a VSX pair can learn routes from one another, in potential failover situations

Must be assigned identical IP address on both of the switches

In Aruba CX 10000 switches, how many SFP28 port-groups are there?

Twelve port-groups with four ports each

Four port-groups with twelve ports each

One port-group that has all the ports

What are two advantages of Campus Attached DC?

Low latency for workloads between DC and Campus

CX Switches come with trusted platform modules (TPM). What is the function of TPM?

TPM stores a certificate signed by an HPE Aruba Networking Certification Authority (CA).

TPM prevents customers from loading certificates signed by the CA of their choice to the switches

TPM is just a convenient name to allow users to connect to the switch securely

TPM stores a certificate signed by GeoTrust Certification Authority (CA).

What does a five-nines requirement in a service agreement refer to?

Unplanned downtime less than .001% of the service term

Compliance with a particular section of PCI DSS

Unplanned downtime less than .001% of the service term

Five layers of redundancy in the network design

Future-proof solution designed to last five or more years

In the ToR or middle of the rack cabling design, it is important to know (Select two)

The number of fiber strands are pulled to each row

The connectors the patch panels use

The number of fiber strands are pulled to each row

The connectors the patch panels use

What is a use case for a two-tier L2 design for a dedicated data center?

Customers with small-to-medium data centers with less demanding requirements

Server room adjacent to campus core

Customers with medium-to-large data centers with application demanding requirements

Customers with small-to-medium data centers with less demanding requirements

Data Center that is located in a separate building to the campus network

Mention two disadvantages of the End-of-Row or Middle-of-Row switches in Data Center design

Longer, more complex cabling within the row

Lower port density and less scalable

Higher latency for rack-to-rack traffic within the row

Longer, more complex cabling within the row

Lower port density and less scalable

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 AccessIn 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.

PVLAN (Private VLAN) defines three types of VLANs under the same SVI

Primary VLAN, Isolated VLAN and Community VLAN

Primary VLAN, Isolated VLAN and Customer VLAN

Secondary VLAN, Isolated VLAN and Provider VLAN

Primary VLAN, Isolated VLAN and Community VLAN

Provider VLAN Service VLAN and QinQ VLAN

Mention two advantages of the ToR switches in Data Center Design

Less unused ports on the switches

You have a customer using Spine and Leaf design with two 8325 32-port 100G QSFP28 (F-B airflow) Spine Switches. What is the maximum number of racks supported if each Rack has two 8360 VSX stacked leaf switches and each spine uses 2 x 100G QSFP28 DACs to each Leaf switch?

Up to 8 total racks using the same subscription rates

Up to 16 total racks using different subscription rates

Up to 4 total racks using the same subscription rates

Up to 4 total racks using different subscription rates

Up to 8 total racks using the same subscription rates

In a Spine and Leaf Design with the following specs:* 8400 100G Spine Switches* 8360 48-P 10G RJ45 Leaf Switches* 100G DAC connections between Spine and LeafsSpine Switches = 8400 with 12 QSFP28 ports (F-B airflow)Each Spine Switch uses:* 1 x 100G QSFP28 5M DACs to each Leaf switchEach Leaf Switch uses:* 1 x 100G QSFP28 5M DACs to each Spine switch* 2 x 100G 1M DAC for ISL* 1 x 10G RJ45 for Keep aliveEach Spine switch can support up to 48 available 100G QSFP28 interfaces.What is the scalability for this solution?
