Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) 認定 JN0-351 試験問題 (Q42-Q47):

質問 # 42
Which two statements are correct about generated routes? (Choose two.)

A. Generated routes appear in the routing table as static routes
B. Generated routes show a next hop in the routing table.
C. Generated routes require a contributing route.
D. Generated routes cannot be redistributed into dynamic routing protocols.

正解：B、C

解説：
A is correct because generated routes require a contributing route. A contributing route is a route that matches the destination prefix of the generated route and has a valid next hop1. A generated route is only installed in the routing table if there is at least one contributing route available2. This ensures that the generated route is reachable and useful. If there is no contributing route, the generated route is not added to the routing table2.
B is correct because generated routes show a next hop in the routing table. A generated route inherits the next hop of its primary contributing route, which is the most preferred route among all the contributing routes2. The next hop of the generated route can be either an IP address or an interface name, depending on the type of the contributing route2. The next hop of the generated route can also be modified by a routing policy3.

質問 # 43
Which two statements about BGP facilitate the prevention of routing loops between two autonomous systems?
(Choose two.)

A. EBGP routers will drop routes that contain their own AS number in the AS_PATH
B. EBGP routers will append their AS number when advertising routes to their neighbors.
C. EBGP routers will prepend their AS number when advertising routes to their neighbors
D. EBGP routers will only accept routes that contain their own AS number in the AS_PATH.

正解：A、B

解説：
Explanation
BGP (Border Gateway Protocol) is a protocol designed to exchange routing and reachability information among autonomous systems (AS) on the internet1.
Option A is correct. When an EBGP router advertises routes to its neighbors, it appends its AS number to the AS_PATH attribute1. This is a key mechanism in BGP to prevent routing loops1.
Option C is correct. BGP has a built-in loop prevention mechanism whereby if a BGP router detects its own AS in the AS_PATH attribute, it will drop the prefix and will not continue to advertise it2. This helps to prevent routing loops2.
Option B is incorrect. EBGP routers do not accept routes that contain their own AS number in the AS_PATH2. Instead, they drop such routes as part of the loop prevention mechanism2.
Option D is incorrect. While it's true that EBGP routers append their AS number when advertising routes, they do not prepend their AS number1. The term "prepend" in BGP usually refers to a technique used to influence path selection by artificially lengthening the AS_PATH3.

質問 # 44
You want to ensure traffic is routed through a GRE tunnel.
In this scenario, which two statements will satisfy this requirement? (Choose two.)

A. All intermediary devices must have a route to the tunnel endpoints.
B. Keepalives must be used on stateless tunneling protocols.
C. BFD must be used on the stateless tunneling protocols.
D. Tunnel endpoints must have a route that directs traffic into the tunnel.

正解：A、D

解説：
Explanation
Option A is correct. For traffic to be sent through a GRE tunnel, there must be a route that directs the traffic into the tunnel. This is typically accomplished through the use of a static route or a dynamic routing protocol.
Option B is correct. All intermediary devices must have a route to the tunnel endpoints34. In real-world scenarios, the tunnel endpoints for a tunnel going over the Internet must have globally reachable internet addresses. Otherwise, intermediate routers in the Internet cannot forward the tunneled packets.

質問 # 45
You are an operator for a network running 1S-IS. Two routers are failing to form an adjacency. What are two reasons for this problem? (Choose two.)

A. There are mismatched router IDs on the L2 routers.
B. There is no configured ISO address on any IS-IS interface.
C. There is a mismatched area ID between the L2 routers.
D. The family iso configuration is missing from the adjacency interface.

正解：B、D

解説：
Explanation
The two reasons for the failure to form an adjacency in a network running IS-IS could be:
B: There is no configured ISO address on any IS-IS interface. IS-IS requires each router interface to have an ISO address configured. Without this address, the routers cannot form an adjacency1.
D: The family iso configuration is missing from the adjacency interface. The 'family iso' configuration is essential for IS-IS to function correctly. If this configuration is missing from the adjacency interface, it could prevent the formation of an adjacency1.
These explanations are based on the Enterprise Routing and Switching Specialist (JNCIS-ENT) documents and learning resources available at Juniper Networks23.

質問 # 46
Which two types of tunnels are able to be created on all Junos devices? (Choose two.)

A. GRE
B. IP-IP
C. IPsec
D. STP

正解：A、C

解説：
Explanation
Junos devices support various types of tunnels for different purposes12.
Option B is correct. Generic Routing Encapsulation (GRE) is a tunneling protocol that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol network1. Junos devices support GRE tunnels1.
Option D is correct. IPsec (Internet Protocol Security) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session1. Junos devices support IPsec tunnels1.
Option A is incorrect. Spanning Tree Protocol (STP) is not a type of tunnel. It's a network protocol designed to prevent loops in a bridged Ethernet local area network2.
Option C is incorrect. While Junos devices do support IP-IP (also known as IP tunneling), it's not supported on all Junos devices1.
