Juniper JN0-232 Online Questions & Answers

• Question 101:

  Which two statements are correct about security zones on an SRX Series device? (Choose two.)

  A. Security zones can be shared between routing instances.
  B. Security zones cannot be shared between routing instances.
  C. Intrazone and interzone traffic both require security policies.
  D. Multiple security zones cannot be configured on an SRX Series device.
  B. Security zones cannot be shared between routing instances.
  C. Intrazone and interzone traffic both require security policies.

  ---

  Routing instances:Security zones are local to their routing instance. Theycannot be shared between routing instances(Option B is correct). Each routing instance must define its own zones. Intrazone and interzone traffic:Both types of traffic require policies in Junos OS. Intrazone traffic must have an explicit intra-zone policy to be controlled (Option C is correct).

  Sharing zones:Option A is incorrect, as zones cannot span routing instances.

  Multiple zones:SRX devices fully support multiple security zones (trust, untrust, DMZ, etc.). Option D is incorrect.

  Correct Statements:B and C

• Question 102:

  Which two IKE Phase 1 configuration options must match on both peers? (Choose two.)

  A. VPN name
  B. gateway interfaces
  C. IKE mode
  D. Diffie-Hellman group
  C. IKE mode
  D. Diffie-Hellman group

  ---

  Phase 1 requires matching IKE mode (main/aggressive) and DH group.

• Question 103:

  Which UI enables you to manage, monitor, and maintain multiple firewalls using a single interface?

  A. Juniper Secure Analytics
  B. Security Director
  C. Juniper Identity Management Service
  D. Secure Connect
  B. Security Director

  ---

  Security Director (Option B):A Junos Space application that provides a centralized interface for managing, monitoring, and maintaining multiple SRX firewalls. Juniper Secure Analytics (Option A):Focuses on SIEM/log analysis, not centralized firewall management.

  Identity Management Service (Option C):Provides user identity integration for policy enforcement, not a management UI. Secure Connect (Option D):A VPN client solution, not a firewall management platform.

  Correct UI:Security Director

• Question 104:

  Which security policy action will cause traffic to drop and a message to be sent to the source?

  A. permit
  B. next-policy
  C. deny
  D. reject
  D. reject

  ---

  Security policies on SRX support several actions: Permit:Allows traffic to pass according to the rule. Deny:Silently drops the traffic without notifying the source.

  Reject:Drops the trafficand sends a TCP RST (for TCP) or ICMP unreachable (for UDP/other protocols)back to the source. This provides feedback to the sending host. Next-policy:Allows policy chaining to evaluate the next policy set. Therefore, the action that causes traffic to drop and a message to be sent to the source isreject.

• Question 105:

  You want to prevent other users from modifying or discarding your changes while you are editing the configuration. Which command accomplishes this task?

  A. configure master
  B. cli privileged
  C. configure exclusive
  D. configure
  C. configure exclusive

  ---

  configure exclusive locks the candidate configuration to a single user.

• Question 106:

  You want to use Avira Antivirus.

  Which two actions should you perform to satisfy this requirement? (Choose two.)

  A. Restart the management daemon (mgd) to load the components.
  B. Enable the Avira engine in operational mode.
  C. Reboot the SRX Series device to load the components.
  D. Enable the Avira engine in configuration mode.
  C. Reboot the SRX Series device to load the components.
  D. Enable the Avira engine in configuration mode.

  ---

  The SRX Series devices support third-party antivirus scanning engines such asAvira. To use the Avira antivirus engine, administrators must explicitly enable the engine and ensure that the required components are properly loaded.

  Enable in configuration mode:

  The Avira antivirus engine must be enabled under UTM configuration mode. This step ensures

  the SRX device uses the Avira scanning engine for antivirus inspection.

  Example:

  set security utm feature-profile anti-virus avira-engine enable Reboot the SRX device:

  A system reboot is required after enabling the Avira engine to load the Avira antivirus components into memory.

  Without a reboot, the Avira engine will not become active.

  Why not the others?

  Restarting themgdprocess (Option A) only reloads the management daemon and does not load antivirus engines.

  Enabling inoperational mode(Option B) is not supported; the configuration must be applied in configuration mode.

  Therefore, the correct actions to use Avira Antivirus are:Enable the Avira engine in configuration mode (Option D) and reboot the SRX device (Option C).

• Question 107:

  Which operating systems are supported for Juniper Secure Connect? (Choose two.)

  A. Linux
  B. Windows 7
  C. Windows 10
  D. MacOS
  C. Windows 10
  D. MacOS

  ---

  Juniper Secure Connect supports modern Windows (10+) and macOS.

• Question 108:

  Which statement is true about ALG (Application Layer Gateway) behavior on SRX devices?

  A. ALGs bypass security policies for well-known protocols.
  B. ALGs modify packet contents to assist protocols with dynamic ports.
  C. ALGs override NAT rules.
  D. ALGs only work in packet-based mode.
  B. ALGs modify packet contents to assist protocols with dynamic ports.

  ---

  ALGs adjust packet headers for protocols like FTP or SIP that negotiate ports dynamically, ensuring proper NAT and state tracking. They do not bypass policies or override NAT rules and require flow mode.

• Question 109:

  You want to verify the effectiveness of Web filtering on the SRX Series Firewall. How would you accomplish this task?

  A. by installing a local NGWF server
  B. by checking the file extensions of blocked content
  C. by examining the content filtering policies
  D. by attempting to access permitted or blocked URLs
  D. by attempting to access permitted or blocked URLs

  ---

  The simplest and most direct method of verifying Web filtering effectiveness isto attempt to access permitted and blocked URLs. Option A:Installing a local NGWF server is not required; NGWF queries Juniper's cloud. Option B:File extension checking applies to content filtering, not web filtering. Option C:Examining policies shows configuration but does not verify enforcement.

  Option D:Correct. Attempting to browse URLs that should be blocked or allowed confirms the Web filtering policy is effective.

  Correct Method:Attempt to access permitted or blocked URLs

• Question 110:

  Which security policy type will be evaluated first?

  A. A zone policy with no dynamic application set
  B. A global with no dynamic application set
  C. A zone policy with a dynamic application set
  D. A global policy with a dynamic application set
  D. A global policy with a dynamic application set

  ---

  Dynamic application global rules have highest evaluation priority.
