Juniper JN0-232 Online Practice Questions and Exam Preparation

Juniper JN0-232 Online Questions & Answers

• Question 111:

  Which type of NAT would you use to ensure that internal users always appear on the Internet with the same public IP address?

  A. Source NAT with a pool of multiple addresses
  B. Source NAT with interface-based translation
  C. Source NAT with a single address pool
  D. Dynamic destination NAT
  C. Source NAT with a single address pool

  ---

  A source NAT rule using a single address pool forces all internal hosts to share a single public IP, providing consistent external identity. Interface-based NAT depends on outgoing interface addressing and may not be static.

• Question 112:

  Which two non-configurable zones exist by default on an SRX Series device? (Choose two.)

  A. Junos-host
  B. functional
  C. null
  D. management
  A. Junos-host
  C. null

  ---

  Junos-host and null are two non-configurable zones that exist by default on an SRX Series device. Junos-host is the default zone for all internal interfaces and services, such as management and other loopback interfaces. The null zone is used to accept all traffic that is not explicitly accepted by other security policies, and is the default zone for all unclassified traffic. Both zones cannot be modified or deleted.

• Question 113:

  You want to integrate an SRX Series device with Juniper ATP Cloud. What is the first action to accomplish this task?

  A. Issue the commit script to register the SRX Series device.
  B. Create an account with the Juniper ATP Cloud Web UI.
  C. Copy the operational script from the Juniper ATP Cloud Web UI.
  D. Create the SSL VPN tunnel between the SRX Series device and Juniper ATP Cloud.
  B. Create an account with the Juniper ATP Cloud Web UI.

  ---

  Registration cannot occur until an ATP Cloud account exists.

• Question 114:

  Corporate security requests that you block all POP3 traffic from traversing the Internet firewall. Which security feature would you use?

  A. antivirus
  B. Web filtering
  C. content filtering
  D. antispam
  C. content filtering

  ---

  Content filtering blocks specific file types and application protocols such as POP3.

• Question 115:

  What is the main purpose of using screens on an SRX Series device?

  A. to provide multiple ports for accessing security zones
  B. to provide an alternative interface into the CLI
  C. to provide protection against common DoS attacks
  D. to provide information about traffic patterns
  C. to provide protection against common DoS attacks

  ---

  Screens mitigate DoS attacks such as SYN floods, port scans, etc.

• Question 116:

  Which Juniper ATP feed provides a dynamic list of known botnet servers and malware download sources?

  A. infected host cloud feed
  B. Geo IP feed
  C. CandC cloud feed
  D. blocklist feed
  C. CandC cloud feed

  ---

  Command-and-Control (CandC) feed identifies botnet control servers.

• Question 117:

  In Junos OS, which statement is correct about packet-based forwarding mode on an SRX device?

  A. It enables AppID for all flows by default.
  B. It bypasses session-based processing.
  C. It supports UTM on all platforms.
  D. It requires NPUs to be disabled.
  B. It bypasses session-based processing.

  ---

  Packet-based mode disables flow-based session creation and processes packets individually, similar to traditional packet filters. AppID and most UTM features require flow-based processing; packet-mode bypasses session tracking.

• Question 118:

  Which two statements are correct about IKE security associations? (Choose two.)

  A. IKE security associations are established during IKE Phase 1 negotiations.
  B. IKE security associations are unidirectional.
  C. IKE security associations are established during IKE Phase 2 negotiations.
  D. IKE security associations are bidirectional.
  A. IKE security associations are established during IKE Phase 1 negotiations.
  D. IKE security associations are bidirectional.

• Question 119:

  Which scenario would require the use of a policy-based VPN instead of a route-based VPN?

  A. You want to enforce encryption only for specific applications.
  B. You want to use st0.* interfaces for forwarding decisions.
  C. You need multi-proxy-ID support for interoperability.
  D. You need dynamic VPN support for remote users.
  A. You want to enforce encryption only for specific applications.

  ---

  Policy-based VPNs match traffic using security policies, enabling selective encryption for specific applications or IP ranges. Route-based VPNs use st0 interfaces and do not filter by application.

• Question 120:

  Which two statements about SRX Series zones are correct? (Choose two.)

  A. The null zone allows the use of security policies to log dropped control plane traffic.
  B. The functional zone is used to define the management interface on smaller SRX Series Firewalls.
  C. A security zone processes intra-zone traffic without a security policy.
  D. The Junos-host zone allows the use of security policies to control access to the SRX Series Firewall.
  C. A security zone processes intra-zone traffic without a security policy.
  D. The Junos-host zone allows the use of security policies to control access to the SRX Series Firewall.

  ---

  Intra-zone traffic:On SRX devices, traffic between interfaces in the same security zone is allowed without requiring a security policy(Option C is correct). Policies are only evaluated for inter-zone traffic.

  Junos-host functional zone:This zone is a predefined functional zone that allows administrators to apply policies controlling access to the SRX firewall itself, such as SSH, HTTP, or SNMP traffic (Option D is correct).

  Null zone:This zone is a predefined discard zone. Interfaces placed in the null zone drop all traffic. It does not allow policy logging of dropped control plane traffic (Option A is incorrect).

  Management functional zone:This is used to define management interfaces, not the "functional zone" as stated in Option B (incorrect wording).

  Correct Statements:C and D
