Question 1
A network engineer is designing OSPF in a multi-area enterprise network. Which
OSPF LSA type is used to advertise routes between different OSPF areas?
A) Type 1
B) Type 2
C) Type 3
D) Type 5
Correct answer: C) Type 3
Rationale: Type 3 LSAs, also known as Summary LSAs, are generated by Area
Border Routers (ABRs) to advertise networks between OSPF areas. They allow
inter-area routing by summarizing and propagating routes. Type 1 and 2 are
intra-area, while Type 5 is used for external routes redistributed into OSPF.
Question 2
What is the primary function of BGP route reflectors in an enterprise network?
A) Eliminate the need for BGP entirely
B) Prevent routing loops in OSPF
C) Reduce iBGP full-mesh requirements
D) Convert eBGP to iBGP
,Correct answer: C) Reduce iBGP full-mesh requirements
Rationale: Route reflectors allow iBGP peers to receive routes without requiring
a full-mesh topology. This improves scalability in large enterprise networks. They
help reduce overhead and complexity while maintaining route propagation.
Question 3
Which protocol is primarily used by Cisco SD-WAN controllers for device
onboarding?
A) OSPF
B) DTLS/TLS
C) EIGRP
D) LDP
Correct answer: B) DTLS/TLS
Rationale: Cisco SD-WAN uses secure DTLS or TLS tunnels to authenticate and
onboard devices to the overlay network. These protocols ensure encrypted
control connections between vBond, vSmart, and WAN Edge routers.
Question 4
What is the administrative distance of a directly connected route?
A) 0
B) 90
C) 110
D) 120
Correct answer: A) 0
Rationale: Directly connected routes have the lowest administrative distance of
0, making them the most trusted routing source. This ensures they are always
preferred over static or dynamic routing protocols.
,Question 5
Which feature in Cisco DNA Center is used for automated network device
configuration?
A) Assurance
B) Provisioning
C) Monitoring
D) Telemetry
Correct answer: B) Provisioning
Rationale: Provisioning in Cisco DNA Center automates device deployment using
templates and plug-and-play functionality. It ensures consistent configuration
across enterprise devices.
Question 6
What is the main purpose of EIGRP successor routes?
A) Backup routes only
B) Primary best path routes
C) External route redistribution
D) BGP path selection
Correct answer: B) Primary best path routes
Rationale: Successor routes in EIGRP are the best paths selected by the DUAL
algorithm and are installed in the routing table as active routes.
Question 7
Which technology allows segmentation of traffic in Cisco SD-Access?
, A) VLAN
B) VRF
C) NAT
D) STP
Correct answer: B) VRF
Rationale: VRF-based segmentation allows SD-Access to isolate traffic logically
across the same physical infrastructure. It enhances security and multi-tenancy.
Question 8
What is the default hello interval for OSPF on broadcast networks?
A) 5 seconds
B) 10 seconds
C) 15 seconds
D) 30 seconds
Correct answer: B) 10 seconds
Rationale: OSPF sends hello packets every 10 seconds on broadcast networks to
maintain neighbor adjacency and detect failures.
Question 9
Which BGP attribute is considered the most important for path selection?
A) MED
B) Local Preference
C) AS Path
D) Weight
Correct answer: D) Weight
Rationale: Cisco-specific BGP weight is the highest priority attribute in route
selection and is locally significant to the router.
