  B. Functional zone cannot be referenced in security policies or pass transit traffic.
  C. Multiple types of functional zones can be defined by the user.
  D. Functional zones are used for out-of-band device management.
  B. Functional zone cannot be referenced in security policies or pass transit traffic.
  D. Functional zones are used for out-of-band device management.

• Question 2:

  Which two statements are correct about unified security policies? (Choose two.)

  A. Traffic that matches a unified policy will not be evaluated by traditional security policy.
  B. Dynamic applications in unified security policies analyze traffic based on Layer 4 information.
  C. Traffic that matches a traditional policy will not be evaluated by unified security policy.
  D. Dynamic applications in unified security policies analyze traffic based on Layer 7 information.
  A. Traffic that matches a unified policy will not be evaluated by traditional security policy.
  D. Dynamic applications in unified security policies analyze traffic based on Layer 7 information.

  Unified security policies (USPs) provide integrated application-aware controls usingAppIDand extend traditional zone-based policy enforcement.

  Option A:Correct. If traffic matches a unified security policy, it is not re-evaluated by traditional security policies. Unified policies take precedence for matched flows. Option B:Incorrect. Traditional policies rely on Layer 3/4 attributes. Unified policies go deeper by leveraging AppID, which inspects traffic up to Layer 7. Option C:Incorrect. Traffic matching a traditional policy is unaffected by unified policy unless unified mode is explicitly configured for those flows. Option D:Correct. Dynamic application recognition

  in unified policies usesLayer 7 (application-layer) inspectionvia AppID. Correct Statements:A and D Reference: Juniper Networks Unified Security Policies and AppSecure AppID, Junos OS Security Fundamentals.

• Question 3:

  You have created a series of security policies permitting access to a variety of services. You now want to create a policy that blocks access to all other services for all user groups. What should you create in this scenario?

  A. global security policy
  B. Juniper ATP policy
  C. IDP policy
  D. integrated user firewall policy
  A. global security policy

  ---

  To enforce acatch-all blocking policyafter other specific policies, the correct solution is aglobal security policy (Option A).

  Global policiescan apply universally across zones, and an administrator can configure a final "deny all"

  rule to block any unmatched traffic.

  ATP policy (Option B):Protects against advanced threats, not used for catch-all rule enforcement.

  IDP policy (Option C):Focuses on intrusion detection and prevention signatures, not general traffic blocking.

  Integrated user firewall policy (Option D):Applies policies based on user identity, but it does not provide a universal block across all services.

  Correct Solution:Global security policy

• Question 4:

  Which two statements are correct about the integrated user firewall feature? (Choose two.)

  A. It maps IP addresses to individual users.
  B. It supports IPv4 addresses.
  C. It allows tracking of non-Windows Active Directory users.
  D. It uses the LDAP protocol.
  A. It maps IP addresses to individual users.
  B. It supports IPv4 addresses.

  ---

  User firewall maps IP-to-user and supports IPv4; tracking non-AD or LDAP use is not applicable.

• Question 5:

  Which two statements are correct about the processing of NAT rules within a rule set? (Choose two.)

  A. NAT rule processing processes all rules.
  B. NAT rule processing stops at the first match.
  C. NAT rules are processed from top to bottom.
  D. NAT rules are processed from bottom to top.
  B. NAT rule processing stops at the first match.
  C. NAT rules are processed from top to bottom.

  ---

  NAT rule processing on SRX devices follows a deterministic order:

  Top-to-bottom order (Option C):NAT rules are always evaluated in the order they appear in the

  configuration, starting at the top.

  First-match wins (Option B):Once a packet matches a NAT rule, processing stops.

  Option A:Incorrect. Not all rules are processed; evaluation stops at the first match.

  Option D:Incorrect. NAT rules are never processed bottom-to-top.

  Correct Statements:NAT rule processing stops at the first match, and NAT rules are processed top-to-bottom.

• Question 6:

  What is an IP addressing requirement for an IPsec VPN using main mode?

  A. One peer must have dynamic IP addressing.
  B. One peer must have static IP addressing.
  C. Both peers must have dynamic IP addresses.
  D. Both peers must have static IP addresses.
  B. One peer must have static IP addressing.

  ---

  Main mode requires at least the responder to use a static IP for identity matching.

• Question 7:

  Which two criteria would be used for matching in security policies? (Choose two.)

  A. MAC address
  B. source address
  C. interface name
  D. applications
  B. source address
  D. applications

  ---

  Security policies in Junos OS match traffic based on specific criteria: Source and destination addresses(Option B). Application(Option D), which may be defined as services (e.g., tcp/80) or recognized through AppID.

  Other options: MAC addresses(Option A) are not used in policy matching; policies operate at Layer 3/4. Interface name(Option C) is used in firewall filters, not in security policy definitions.

  Correct Criteria:Source address and Applications

• Question 8:

  Your manager asks you to verify when your antivirus definitions were last updated on your SRX Series Firewall. Which operational mode command allows you to see this information?

  A. show security utm content-filtering statistics
  B. show security utm anti-spam status
  C. show security web filtering status
  D. show security utm anti-virus status
  D. show security utm anti-virus status

  ---

  The antivirus feature on SRX relies on signature definition files that must be regularly updated. To check the status of these updates, the correct operational command is:

  show security utm anti-virus status(Option D). This displays details such as:

  Antivirus engine status

  Last update time of virus definitions

  Version of the signature database

  Other options: Content-filtering statistics (Option A) shows counters for file-type filtering, not antivirus updates. Anti-spam status (Option B) shows spam filtering engine connectivity. Web filtering status (Option C) shows SBL/web filter server connection details.

  Correct Command:show security utm anti-virus status

• Question 9:

  Your company wants protection from ransomware attacks. Which solution satisfies this requirement?

  A. screens
  B. unified security policies
  C. AppSecure
  D. Juniper ATP Cloud
  D. Juniper ATP Cloud

  ---

  ATP Cloud performs advanced malware analysis and ransomware detection.

• Question 10:

  Click the Exhibit button.

  

  The exhibit shows a table representing security policies from the trust zone to the untrust zone. In this scenario, which two statements are correct? (Choose two.)

  A. SSH requests from the source IP address of 172.25.11.10 are permitted to the destination IP address of 10.1.0.10.
  B. Ping command requests from the source IP address of 172.25.11.100 are denied to the destination IP address of 10.1.0.10.
  C. FTP requests from the source IP address of 10.1.0.10 are permitted to the destination IP address of 172.25.11.100.
  D. FTP requests from the source IP address of 172.25.11.11 are denied to the destination IP address of 10.1.0.10.
  A. SSH requests from the source IP address of 172.25.11.10 are permitted to the destination IP address of 10.1.0.10.
  D. FTP requests from the source IP address of 172.25.11.11 are denied to the destination IP address of 10.1.0.10.

  Juniper SRX evaluatessecurity policiessequentially from top to bottom. Once a policy match is found, no further policies are evaluated. In this exhibit:

  First Policy (FTP, deny):

  Source: 172.25.11.0/24

  Destination: 10.1.0.0/16

  Application: FTP

  Action: deny#Any FTP traffic from 172.25.11.0/24 to 10.1.0.0/16 isdenied.

  Second Policy (SSH, permit):

  Same source/destination but application = SSH

  Action = permit#SSH traffic from 172.25.11.0/24 to 10.1.0.0/16 ispermitted.

  Third Policy (HTTPS, permit):#HTTPS from the same source/destination ispermitted.

  Fourth Policy (Ping, permit):

  Source: 172.25.11.0/24 to any destination Application: ping Action: permit#ICMP echo requests (ping) from 172.25.11.0/24 to any destination arepermitted. Fifth Policy (any # any, deny):#Serves as a defaultdeny allat the end.

  Now checking each option: Option A:SSH from 172.25.11.10 # 10.1.0.10 matches theSSH permit rule(second policy).#Correct. Option B:Ping from 172.25.11.100 # 10.1.0.10 matches theping permit rule(fourth policy). This traffic is permitted, not denied.#Incorrect.

  Option C:FTP from 10.1.0.10 # 172.25.11.100 isreverse traffic (untrust to trust). The table applies

  onlytrust # untrust, so this policy does not apply.#Incorrect.

  Option D:FTP from 172.25.11.11 # 10.1.0.10 matches the first policy (FTP deny rule).#Correct.

  Correct Statements:A, D
