Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q114-Q119):

NEW QUESTION # 114
Which statement is correct about areas in OSPF?

  • A. OSPF areas are used to isolate the effects of a broadcast storm.
  • B. An OSPF area is used to segment Layer 2 broadcast domains.
  • C. OSPF areas are used to reduce the size of the link-state database.
  • D. An OSPF area is used to signify the autonomous system to which each device belongs.

Answer: C

Explanation:
InOSPF (Open Shortest Path First), areas are used to segment a network into smaller, more manageable pieces to improve scalability. By dividing a network into areas, OSPF can reduce the size of thelink-state database (LSDB), which helps routers process updates more efficiently.
Step-by-Step Breakdown:
* Purpose of OSPF Areas:OSPF areas allow for hierarchical routing within the OSPF domain. Routers in the same area have identical LSDBs, but routers in different areas do not exchange full link-state information. Instead, they exchange summarized routes, which reduces the LSDB size and CPU
/memory usage.
* Benefits:Reducing the LSDB size improves scalability and ensures faster convergence in larger networks. Area 0 is the backbone area, and all other areas must connect to it, forming a hierarchical structure.
Juniper Reference:
* OSPF Configuration: Areas in OSPF are configured to optimize network performance by limiting the scope of link-state advertisements (LSAs) to within an area.


NEW QUESTION # 115
Which of the following VLAN port modes exist in Junos OS? (Choose two)

  • A. Trunk
  • B. Access

NEW QUESTION # 116
Exhibit:

Referring to the exhibit, which next hop will be preferred in the routing table?

  • A. Next hop IP address 172.25.20.254 will be preferred.
  • B. Both next hops will be preferred.
  • C. Neither next hop will be preferred.
  • D. Next hop IP address 172.25.20.200 will be preferred.

Answer: D

Explanation:
In the exhibit, we see a static route configuration with two possible next hops for the default route (0.0.0.0/0):
* next-hop 172.25.20.254with the default preference of 7.
* qualified-next-hop 172.25.20.200with a preference of 6.
Step-by-Step Breakdown:
* Preference Value:In Junos OS, thepreferencevalue is used to determine which route should be preferred in the routing table. The lower the preference value, the higher the priority for the route.
* Comparison:In this case:
* The next hop172.25.20.254has a preference of7.
* Thequalified-next-hop 172.25.20.200has a preference of6.
* Preferred Next Hop:Since172.25.20.200has a lower preference (6) compared to172.25.20.254(7), it will be the preferred next hop in the routing table, assuming both next hops are reachable.
Juniper Reference:
* Qualified Next Hop: In Junos, static routes with multiple next-hop options are selected based on the preference value, with the lower value being preferred.


NEW QUESTION # 117
