Juniper Security, Professional (JNCIP-SEC) 認定 JN0-637 試験問題 (Q113-Q118):
質問 # 113
Exhibit
Which two statements are correct about the output shown in the exhibit? (Choose two.)
- A. The packet matches the default security policy.
- B. The packet is processed in the first path packet flow.
- C. The packet is processed as host inbound traffic.
- D. The packet matches a configured security policy.
正解:A、C
質問 # 114
You are asked to configure tenant systems.
Which two statements are true in this scenario? (Choose two.)
- A. A tenant system can have only one administrator.
- B. After successful configuration, the changes are merged into the primary database for each tenant system.
- C. You can commit multiple tenant systems at a time.
- D. Tenant systems have their own configuration database.
正解:C、D
解説:
Each tenant system maintains its own configuration database, isolating configurations from others, enhancing security and operational efficiency. Junos OS supports multiple concurrent commit operations across tenant systems. Further details are covered in the Juniper Tenant System Guide.
When configuring tenant systems on an SRX device, the following principles apply:
* Tenant Systems Have Their Own Configuration Database (Answer C): Each tenant system has its own isolated configuration database, ensuring that changes made in one tenant system do not affect others. This allows for multi-tenant environments where different tenants can have independent configurations.
* Commit Multiple Tenant Systems Simultaneously (Answer D): The system allows for multiple tenant systems to be committed at the same time, simplifying management when working with multiple tenants. This is particularly useful in large environments where multiple logical systems or tenants need updates simultaneously.
質問 # 115
A company has acquired a new branch office that has the same address space as one of its local networks,
192.168.100.0/24. The offices need to communicate with each other.
Which two NAT configurations will satisfy this requirement? (Choose two.)
- A. [edit security nat source]
user@OfficeB# show rule-set OfficeAtoB {
from zone OfficeA;
to zone OfficeB;
rule 1 {
match {
source-address 192.168.200.0/24;
destination-address 192.168.210.0/24;
}
then {
source-nat { interface; }
}
}
}
- B. [edit security nat static]
user@OfficeB# show rule-set From-Office-A {
from interface ge-0/0/0.0;
rule 1 {
match {
destination-address 192.168.210.0/24;
}
then {
static-nat {
prefix { 192.168.100.0/24; }
}
}
}
}
- C. [edit security nat source]
user@OfficeA# show rule-set OfficeBtoA {
from zone OfficeB;
to zone OfficeA;
rule 1 {
match {
source-address 192.168.210.0/24;
destination-address 192.168.200.0/24;
}
then {
source-nat { interface; }
}
}
}
- D. [edit security nat static]
user@OfficeA# show rule-set From-Office-B {
from interface ge-0/0/0.0;
rule 1 {
match {
destination-address 192.168.200.0/24;
}
then {
static-nat {
prefix { 192.168.100.0/24; }
}
}
}
}
正解:B、D
解説:
Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References When two networks with overlapping IP address spaces need to communicate, Network Address Translation (NAT) is required to translate the IP addresses so that they become unique across the combined network. In this scenario, both the local network and the new branch office use the same subnet: 192.168.100.0/24. To enable communication without IP conflicts, we need to translate the overlapping addresses to unique ones.
Understanding the Problem:
* Local Network (Office A): 192.168.100.0/24
* Branch Office (Office B): 192.168.100.0/24
* Objective: Allow communication between Office A and Office B despite overlapping IP ranges.
Solution Overview:
To resolve the overlapping IP addresses, we can use Static NAT to create a one-to-one mapping between the overlapping IP addresses and a unique IP range. This way, when packets traverse the network boundary, their IP addresses are translated to a non-overlapping range, avoiding conflicts.
Option B and Option C implement Static NAT to resolve the issue:
* Option B (At Office A):
* Translates destination addresses from 192.168.200.0/24 to 192.168.100.0/24.
* This allows Office B to reach Office A's overlapping network by targeting a unique IP range (
192.168.200.0/24).
* Option C (At Office B):
* Translates destination addresses from 192.168.210.0/24 to 192.168.100.0/24.
* This allows Office A to reach Office B's overlapping network by targeting a unique IP range (
192.168.210.0/24).
Detailed Explanation:
1. Static NAT Configuration at Office A (Option B):
* Configuration:
[edit security nat static]
user@OfficeA# show rule-set From-Office-B {
from interface ge-0/0/0.0;
rule 1 {
match {
destination-address 192.168.200.0/24;
}
then {
static-nat {
prefix { 192.168.100.0/24; }
}
}
}
}
* Explanation:
* from interface ge-0/0/0.0;: Specifies the interface through which the traffic is received.
* Matching Traffic:
* destination-address 192.168.200.0/24;: Matches packets destined for 192.168.200.0/24.
* Action:
* static-nat { prefix { 192.168.100.0/24; } }: Translates the destination address to
192.168.100.0/24.
* Result:
* Office B sends packets to 192.168.200.0/24, which are translated to 192.168.100.0/24 upon arrival at Office A.
