Juniper JN0-232 Online Questions & Answers

• Question 131:

  What does the number "2" indicate in interface ge-0/1/2?

  A. The interface logical number
  B. The physical interface card (PIC)
  C. The port number
  D. The flexible PIC concentrator (FPC)
  C. The port number

  ---

  ge-FPC/PIC/Port - the last digit represents the physical port.

• Question 132:

  You are asked to create a security policy that controls traffic allowed to pass between the Internet and private security zones. You must ensure that this policy is evaluated before all other policy types on your SRX Series device. In this scenario, which type of security policy should you create?

  A. routing policy
  B. default policy
  C. zone policy
  D. global policy
  D. global policy

  ---

  Global policies (Option D):Evaluated before zone-based policies. They allow centralized control and can apply across all zones. Perfect for Internet-to-private traffic that must be enforced before other rules.

  Routing policy (Option A):Controls routing decisions, not traffic forwarding/security.

  Default policy (Option B):Denies all traffic by default, but cannot be customized for early evaluation.

  Zone policy (Option C):Zone-based policies apply after global policies and are limited to specific zone pairs. Correct Policy Type:Global policy

• Question 133:

  What must be enabled on an SRX Series device for the reporting engine to create reports?

  A. System logging
  B. SNMP
  C. Packet capture
  D. Security logging
  D. Security logging

  ---

  The reporting engine depends on security logs to generate reports.

• Question 134:

  Which statement is correct regarding security policies using address books?

  A. Address books can only be configured globally.
  B. Zone-specific address books require interfaces to share the same routing instance.
  C. Address books cannot include IP prefixes.
  D. Address books are only used for NAT rules.
  B. Zone-specific address books require interfaces to share the same routing instance.

  ---

  Zone-specific address books are bound to a routing instance because zones cannot span multiple instances. Address books can be global or per-zone and allow prefixes, IPs, and sets.

• Question 135:

  Which statement is correct about unified security policies on an SRX Series device?

  A. A zone-based policy is always evaluated first.
  B. The most restrictive policy is applied regardless of level.
  C. A global policy is always evaluated first.
  D. The first policy rule is applied regardless of level.
  D. The first policy rule is applied regardless of level.

  ---

  Unified policy evaluation is first-match, policy level does not override order.

• Question 136:

  You have a situation where legitimate traffic is incorrectly identified as malicious by your screen options. In this scenario, what should you do?

  A. Enable all screen options.
  B. Discard the traffic immediately.
  C. Increase the sensitivity of the screen options.
  D. Use the alarm-without-drop configuration parameter.
  D. Use the alarm-without-drop configuration parameter.

  ---

  Screen options are used to detect and prevent attacks such as floods, scans, and malformed packets. In some cases,false positivesmay occur, where legitimate traffic is mistakenly identified as malicious.

  To address this, administrators can configure thealarm-without-dropoption (Option D). This setting generates alarms/logs for suspicious traffic without actually dropping it, allowing verification before taking further action.

  Enabling all screen options (Option A) may increase false positives further.

  Discarding traffic immediately (Option B) risks disrupting legitimate communication.

  Increasing sensitivity (Option C) worsens the problem, since false positives would increase.

  Correct Action:Use alarm-without-drop to log the traffic without dropping it.

• Question 137:

  Which two security policies are installed by default on SRX 300 Series Firewalls? (Choose two.)

  A. a security policy to allow all traffic from the untrust zone to the trust zone
  B. a security policy to allow all traffic from the trust zone to the untrust zone
  C. a security policy to allow all traffic from the management zone to the trust zone
  D. a security policy to allow all traffic from the trust zone to the trust zone
  B. a security policy to allow all traffic from the trust zone to the untrust zone
  D. a security policy to allow all traffic from the trust zone to the trust zone

  ---

  By default, SRX 300 Series Firewalls come with predefined security policies:

  Trust-to-Untrust (Option B):A default policy exists to permit all traffic from thetrust zone to the untrust zone.

  Trust-to-Trust (Option D):Intra-zone traffic is permitted by default; hence, a trust-to-trust policy is installed automatically.

  Untrust-to-Trust (Option A):Not allowed by default, since external traffic must be explicitly

  permitted by an administrator.

  Management-to-Trust (Option C):No such default policy exists.

  Correct Policies:Trust-to-Untrust and Trust-to-Trust

• Question 138:

  In which order does Junos OS process the various forms of NAT?

  A. static NAT, destination NAT, source NAT
  B. destination NAT, source NAT, static NAT
  C. source NAT, static NAT, destination NAT
  D. source NAT, destination NAT, static NAT
  A. static NAT, destination NAT, source NAT

  ---

  NAT processing in Junos OS follows a strict sequence to ensure correct packet handling: Static NAT?applied first because it provides a permanent one-to-one bidirectional mapping. Destination NAT?applied second to translate inbound destination addresses, often used for servers in private networks. Source NAT?applied last to translate outbound private source addresses to public ones. This ensures deterministic behavior and avoids conflicts between translation types.

  Options B, C, and D list incorrect sequences.

  Correct Order:static NAT # destination NAT # source NAT

• Question 139:

  What are two features of the Juniper ATP Cloud service? (Choose two.)

  A. sandbox
  B. malware detection
  C. EX Series device integration
  D. honeypot
  A. sandbox
  B. malware detection

  ---

  ATP Cloud provides cloud sandboxing and malware detection capabilities.

• Question 140:

  On an SRX Series firewall, which log type records events generated by UTM and security services such as Web filtering or antivirus scanning?

  A. interactive-commands
  B. traffic
  C. event
  D. utm
  D. utm

  ---

  The utm log category captures logs specific to UTM features-web filtering, antivirus, antispam, and content filtering-distinct from general traffic or event logs.
