CCIE Enterprise Infrastructure Practice Test
Exam
1. In Cisco SD-Access, which protocol is used for the control
plane to provide endpoint identifier-to-routing locator
mapping?
A) VXLAN
B) LISP
C) OMP
D) BGP
Correct Answer: B
Rationale: LISP is the control plane protocol in SD-Access that
provides the mapping between endpoint identifiers (EIDs) and
routing locators (RLOCs), enabling anywhere routing within the
fabric .
2. In a VXLAN BGP EVPN fabric, what is the purpose of a Type 3
route?
A) To advertise MAC addresses of endpoints
,B) To advertise the VTEP IP address for BUM traffic replication
C) To advertise IP prefixes for Layer 3 routing
D) To advertise VLAN to VNI mappings
Correct Answer: B
Rationale: Type 3 routes, known as Inclusive Multicast Ethernet
Tag routes, advertise the VTEP IP address and are used for
head-end replication of BUM traffic in the VXLAN fabric.
3. What is a key advantage of StackWise Virtual technology on
Catalyst 9000 switches?
A) It eliminates the need for VXLAN
B) It provides active-active data plane with Multichassis
EtherChannel
C) It replaces BGP with OSPF for routing
D) It removes the need for QoS policies
Correct Answer: B
Rationale: StackWise Virtual allows both switches to actively
forward traffic and supports Multichassis EtherChannel,
,providing double bandwidth and reduced latency with sub-
second convergence .
4. In VRF route leaking on IOS-XE, which command is used to
leak routes between two VRFs?
A) route-target export
B) import map
C) vrf forwarding
D) ip route vrf
Correct Answer: B
Rationale: The import map command is used under VRF
address-family configuration to reference a route-map that
controls which routes are leaked into the VRF .
5. In OSPFv3 address family configuration, how is the IPv4
address family enabled?
A) ipv4 unicast-routing
B) router ospfv3 process-id
C) address-family ipv4 unicast
, D) ospfv3 ipv4 area
Correct Answer: C
Rationale: The OSPFv3 address families feature allows IPv4 and
IPv6 to be configured separately using the address-family ipv4
unicast command under the router ospfv3 process .
6. In a VXLAN BGP EVPN fabric, which route type is used to
advertise host MAC and IP address information?
A) Type 1
B) Type 2
C) Type 3
D) Type 5
Correct Answer: B
Rationale: Type 2 routes, known as MAC/IP Advertisement
routes, carry endpoint MAC addresses and optionally IP
addresses in the EVPN control plane.
7. What is the purpose of the register-route-notifications
command in a LISP-enabled VXLAN fabric?
