最新的 JNCIA JN0-105 免費考試真題 (Q49-Q54):

問題 #49
You are configuring a firewall filter on a Juniper device.
In this scenario, what are two valid terminating actions? (Choose two.)

  • A. 2discarD
  • B. 3next term
  • C. 4accept
  • D. 1 count

答案:A,C

解題說明:
In Juniper firewall filter configurations, "discard" and "accept" are two valid terminating actions for a term within a filter. The "discard" action drops the packet, preventing it from reaching its intended destination, while the "accept" action allows the packet to pass through the filter, proceeding to its next hop or destination. "Count" is a non-terminating action that increments a counter every time a packet matches the term but does not inherently determine the packet's fate. "Next term" directs the evaluation to proceed to the next term in the filter for further processing, also a non-terminating action.

問題 #50
Exhibit
user@router> show route 192.168.36.1
inet.O: 5 destinations, 6 routes (5 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both
192.168.36.1/32 *[Static/5] 00:00:31
> to 10.1.1.2 via ge-0/0/10.0 [OSPF/IO] 00:02:21, metric 1 > to 10.1.1.2 via ge-0/0/10.0 Referring to the exhibit, which route(s) will be selected by Junos for packet forwarding?

  • A. The static route will be selected.
  • B. The OSPF route will be selected.
  • C. The Junos OS selects both routes.
  • D. The Junos OS randomly selects one route.

答案:A

解題說明:
Junos OS selects routes based on the route preference (also known as administrative distance). Static routes typically have a lower route preference than OSPF routes, meaning they are more preferred. Since the static route to 192.168.36.1/32 is shown with a preference of 5, it will be selected over the OSPF route for packet forwarding, assuming no other factors such as route filters or policies affect the routing decision.

問題 #51
Which two statements are correct about firewall filters? (Choose two.)

  • A. There can be multiple firewall filters.
  • B. "Discard" is the default action of packets that are not explicitly allowed.
  • C. "Accept" is the default action of packets that are not explicitly allowed.
  • D. There can be only one firewall filter.

答案:A,B

解題說明:
In Juniper Networks devices, firewall filters are used to control packet flow through the device. The default action for packets that do not match any of the specified criteria in the firewall filter is to discard them, enhancing network security by ensuring that only explicitly allowed traffic can pass through. Furthermore, it is possible to configure multiple firewall filters on a device, allowing for granular control over traffic based on various criteria such as source, destination, and protocol type.

問題 #52
Click the Exhibit button.

Referring the exhibit, what does the highlighted number indicate?

  • A. metric is 5
  • B. route preference is 5
  • C. hop count is 5
  • D. cost is 5

答案:B

解題說明:
In the exhibit shown, the highlighted number next to the route type (Static) within the square brackets indicates the route preference, also known as the administrative distance. In Junos, the route preference is a value that determines the priority of the route source. Lower numbers indicate a higher priority when the routing table is being calculated. The route preference is used to select the best route when multiple paths to the same destination exist from different routing sources. The number 5 is unusually low for a static route by default, suggesting it has been manually configured to override other route types.

問題 #53
When considering routing tables and forwarding tables, which two statements are correct? (Choose two.)

  • A. The forwarding table stores all routes and prefixes from all protocols.
  • B. The routing table stores all routes and prefixes from all protocols.
  • C. The routing table is used by the RE to select the best route.
  • D. The forwarding table is used by the RE to select the best route.

答案:B,C

解題說明:
The routing table and forwarding table play distinct roles in a Junos OS device. The correct answers are A and D.
The routing table (A) is used by the Routing Engine (RE) to select the best route among all the learned routes, while the routing table (D) stores all routes and prefixes learned from all routing protocols. The forwarding table, in contrast, contains only the active routes chosen by the RE and is used by the Packet Forwarding Engine for actual packet forwarding.
