RATIONALES. A+ GRADED
1. An OSPF router in an NSSA area receives a Type 7
LSA from an ASBR. How does the ABR handle this
LSA when translating to Type 5?
A) It translates the Type 7 LSA to Type 5 LSA and
floods it into other areas
B) It discards the Type 7 LSA without translation
C) It translates the Type 7 LSA to Type 3 LSA
D) It floods the Type 7 LSA unchanged into the
backbone
Correct answer: A
Rationale: NSSA ASBRs generate Type 7 LSAs. The
ABR translates Type 7 to Type 5 LSA and injects them
into the backbone and other areas (unless
suppressed).
,2. Which of the following OSPF network types does
not elect a DR/BDR and uses multicast address
224.0.0.5 (all OSPF routers)?
A) Broadcast
B) Non-broadcast (NBMA)
C) Point-to-point
D) Point-to-multipoint
Correct answer: C
Rationale: Point-to-point and point-to-multipoint
networks do not elect DR/BDR. Broadcast and NBMA
do elect DR/BDR. Hello is sent to 224.0.0.5.
3. An EIGRP router receives a query for a lost route.
It does not have a feasible successor. What action
does the router take?
A) It replies with an infinite metric (indicates the route
is lost)
B) It sends a query to all its neighbors
C) It marks the route as passive
D) It stops the DUAL computation
Correct answer: B
,Rationale: If a router has no feasible successor, it
transitions to active state and sends EIGRP query
packets to all neighbors for that destination.
4. Which of the following BGP path attributes is well-
known discretionary?
A) AS_PATH
B) NEXT_HOP
C) LOCAL_PREF
D) ORIGIN
Correct answer: C
Rationale: Well-known mandatory: AS_PATH,
NEXT_HOP, ORIGIN. Well-known discretionary:
LOCAL_PREF. Optional transitive: COMMUNITY.
5. A network engineer wants to filter BGP prefixes
inbound from an eBGP peer. Which method is most
appropriate?
A) Distribute-list with a prefix-list applied in the
inbound direction
B) Route-map with deny statement applied inbound
C) Prefix-list with le and ge parameters
D) All of the above
, Correct answer: D
Rationale: BGP inbound filtering can use distribute-
list (with ACL/prefix-list), route-map, or prefix-list
directly. Prefix-list with le/ge matches subnet mask
ranges.
6. In IS-IS, which PDU type is used to carry link-state
information (similar to OSPF LSA)?
A) IIH (IS-IS Hello)
B) LSP (Link State PDU)
C) CSNP (Complete Sequence Number PDU)
D) PSNP (Partial Sequence Number PDU)
Correct answer: B
Rationale: IS-IS LSPs (Type 1) carry link-state
information. IIHs form adjacencies. CSNP/PSNP are
used for database synchronization.
7. Which of the following is a valid IS-IS router level
for a router that only needs to know routes within its
own area and uses a default route to reach other
areas?
A) Level-1
B) Level-2
