Juniper Security, Associate (JNCIA-SEC) 認定 JN0-232 試験問題 (Q10-Q15):

質問 # 10
What are two valid security address objects within Juniper Networks? (Choose two.)

A. global address object
B. prefix address object
C. routing address object
D. MAC address object

正解：A、B

解説：
Juniper security address objects are defined in address books and are used by features such as security policies and NAT. A global address object is valid because Junos supports a global address book that is available across security zones without attaching it to a specific zone. A prefix address object is also valid because Juniper allows addresses to be specified in network prefix format, such as 203.0.113.0/24. Routing address object is not a standard Junos security address-book object type. MAC address object is not the normal address object used for SRX security policy address matching, which primarily uses IPv4, IPv6, DNS, wildcard, and address-range entries.

質問 # 11
Which two statements are correct about security zones and functional zones? (Choose two.)

A. Traffic entering an interface in a functional zone can exit any other transit interface.
B. Traffic entering transit interfaces cannot exit an interface in a functional zone.
C. Traffic entering an interface in a functional zone cannot exit any other transit interface.
D. Traffic entering transit interfaces can exit an interface in a functional zone.

正解：B、C

解説：
* Functional zones(e.g., junos-host, management, null) are not used for forwarding transit traffic. They are used to manage traffic destined to or from the SRX device itself.
* Option A:Correct. If traffic enters through a functional zone interface, it is meant for the SRX, not for transit, so it cannot exit another interface.
* Option D:Correct. Transit interfaces handle forwarding traffic, but they cannot send that traffic out through a functional zone interface.
* Option B and C:Incorrect, because functional zones are strictly control-plane, not transit forwarding zones.
Correct Statements:A and D
Reference:Juniper Networks -Security Zones vs. Functional Zones, Junos OS Security Fundamentals.

質問 # 12
Which two statements are correct about the null zone on an SRX Series device? (Choose two.)

A. The null zone is a functional security zone.
B. The null zone is created by default.
C. You must enable the null zone before you can place interfaces into it.
D. Traffic sent or received by an interface in the null zone is discarded.

正解：B、D

解説：
According to the Juniper SRX Series Services Guide, the null zone is a predefined security zone that is created on the SRX Series device when it is booted. Traffic that is sent to or received on an interface in the null zone is discarded. The null zone is not a functional security zone, so you cannot enable or disable it.

質問 # 13
Which two statements about the host-inbound-traffic parameter in a zone configuration are correct? (Choose two.)

A. Deleting the host-inbound-traffic parameter blocks console access to the firewall.
B. The host-inbound-traffic parameter is explicitly configured in a security zone.
C. Deleting the host-inbound-traffic parameter blocks SSH access to the firewall.
D. The host-inbound-traffic parameter is implicitly configured in the management zone.

正解：B、C

解説：
* SSH Access (Option B):Host-inbound-traffic controls traffic destined to the SRX device itself (management/control plane). If host-inbound-traffic is not configured to allow SSH, then SSH access to the firewall is blocked.
* Explicit Zone Configuration (Option D):For user-defined security zones, host-inbound-traffic must be explicitly configured to allow specific services (SSH, ICMP, SNMP, etc.).
* Console Access (Option A):Console access is not controlled by host-inbound-traffic. Console access is always available directly.
* Management Zone (Option C):In the management functional zone, host-inbound-traffic is implicitly allowed for management services, so this is not explicitly required.
Correct Statements:B and D
Reference:Juniper Networks -Host-Inbound-Traffic and Zone Services, Junos OS Security Fundamentals.

質問 # 14
Which statement is correct about security policies?

A. Zone-based security policies only apply to intra-zone traffic.
B. Security policies are evaluated before screen in first path processing.
C. Zone-based security policies reference both source and destination zones.
D. Security policies are evaluated in both first path and fast path processing.

正解：C

解説：
Zone-based security policies in Junos OS always reference both a source zone and a destination zone. Traffic must match both zones for the policy to be applied, which defines how traffic is permitted or denied between those zones.
