Questions & Answers for Cisco 700-703

Showing 1-15 of 50 Questions

Question #1

Which application-centric infrastructurecontainer isused for IP subnetsand can be used to
define a Layer 2 boundary?

A. bridgedomain

B. tenant

C. endpointgroup

D. VLAN

E. Privatenetwork(layer 3)

Explanation:
A bridge domain is a construct used to define a Layer 2 boundary within the fabric. A bridge
domain can be viewed as somewhat similar to regular VLANs in a traditional switching
environment.
✑ Specify a bridge domain in the private network.
✑ Specify the bridge domain name in the Name field (BD1).
✑ Click the + sign next to Subnets to add a public subnet (192.168.1.254/24) to
associate with BD1. This public subnet will advertise to ISP1

Question #2

Which two new operational modelsare driving the need for infrastructurechange in business
today?(Choose two)

A. Big data

B. Increased time to market

C. Increased data center costs

D. Cloud computing

E. Increasing IT staff

Question #3

Which aspect of an endpoint group contract is optional?

A. Action

B. Subject

C. filter

D. label

Explanation: Labels, which are used optionally to group objects such as subjects and
EPGs for the purpose of further defining policy enforcement

Question #4

Which logical representation of policies between endpoint groups in application-centric
infrastructure isprovidedby one EPG andconsumedby another?

A. VLAN

B. private network (Layer 3)

C. endpoint group

D. tenant

E. contract

Question #5

Which option describeswhat is included in theACIVXLAN header with which all tenanttraffic
within the fabric is tagged?

A. Policy group (source group),forwardinggroup(tenant,VRF, bridge domain),destinationIP addressgroup, and source IPaddress group.

B. Policygroup (source group)forwarding group (tenant, VRF, bridge domain), load- balancing policy, andtelemetry policy.

C. Flow mapping of endpointgroupsto applications,Layers3 external identifiersand leaf associationof application profiles.

D. Destination IP address group source IP address group,forwardinggroup, load-balancing policy and telemetry policy.

Explanation:
All Tenant traffic within the Fabric is tagged with an ACI VXLAN (VXLAN) header which
identifies the policy attributes of the application end point within the fabric
Policy Group (source group)
Forwarding Group (Tenant, VRF,
Bridge Domain)
Load Balancing Policy

Question #6

Which protocols are used to resolve hypervisor-to-leaf node attachment in an ACI fabric?

A. COOP or OpFlex

B. LLDP or COOP

C. LLDP or OpFlex

D. LACP or OpFlex

Explanation: LLDP or OpFlex permissions are used to resolve the hypervisor to leaf node
attachments.

Question #7

Which protocol is used in the ACI fabric for topology discovery?

A. Equal-cost multipath

B. Link layer discovery protocol

C. Cisco discovery protocol

D. Link aggregation control protocol

Explanation: The APIC startup topology auto discovery, automated configuration, and
infrastructure addressing uses these industry-standard protocols: Intermediate System-to-
Intermediate System (IS-IS), Link Layer Discovery Protocol (LLDP), and Dynamic Host
Configuration Protocol (DHCP).
