NEW QUESTION # 38
Which two statements about management functional zones are correct? (Choose two.)
- A. The management functional zone contains all available revenue ports until they are assigned to a user- defined security zone.
- B. The management functional zone is used to control the management-related traffic that is allowed to access your device.
- C. The management functional zone is automatically created on the SRX Series Firewalls.
- D. The management functional zone cannot be referenced in any security policies.
Answer: B,C
Explanation:
Themanagement functional zoneon SRX devices is a special predefined zone with unique characteristics:
* It isautomatically created(Option C) and cannot be deleted.
* It is used specifically formanagement-related traffic(Option A), such as SSH, Telnet, web management (J-Web), SNMP, and other control-plane services.
* It does not contain revenue (data) interfaces (Option B is incorrect). Interfaces must be explicitly configured into user-defined zones.
* The management zone can be referenced in policies if inter-zone communication involving management traffic is needed (Option D is incorrect).
Correct Statements:A and C

NEW QUESTION # 39
Which two statements are correct about unified security policies? (Choose two.)
- A. Dynamic applications in unified security policies analyze traffic based on Layer 7 information.
- B. Traffic that matches a unified policy will not be evaluated by traditional security policy.
- C. Dynamic applications in unified security policies analyze traffic based on Layer 4 information.
- D. Traffic that matches a traditional policy will not be evaluated by unified security policy.
Answer: A,B
Explanation:
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

NEW QUESTION # 40
You are modifying the NAT rule order and you notice that a new NAT rule has been added to the bottom of the list.
In this situation, which command would you use to reorder NAT rules?
- A. top
- B. insert
- C. run
- D. up
Answer: A
Explanation:
In Junos OS, NAT rules are evaluated intop-down order. When a new rule is added, it is placed at thebottom of the rule set by default.
* To move a rule to the top of the rule set, the command is:
* set security nat source rule-set <name> rule <rule-name> top
* Option A (top):Correct. Moves the specified rule to the top of the list.
* Option B (run):Used to execute operational commands, not rule reordering.
* Option C (up):Not valid for reordering NAT rules.
* Option D (insert):Not a supported NAT reordering command in Junos.
Correct Command:top

NEW QUESTION # 41
Which security policy action will cause traffic to drop and a message to be sent to the source?
- A. next-policy
- B. permit
- C. reject
- D. deny
Answer: C
Explanation:
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.

NEW QUESTION # 42
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 management zone to the trust zone
- B. a security policy to allow all traffic from the trust zone to the trust zone
- C. 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 untrust zone to the trust zone
Answer: B,C
Explanation:
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
Reference:Juniper Networks -Default Security Policies and Intra-zone Rules, Junos OS Security Fundamentals.
NEW QUESTION # 43
You want to use Avira Antivirus.
Which two actions should you perform to satisfy this requirement? (Choose two.)
- A. Enable the Avira engine in operational mode.
- B. Enable the Avira engine in configuration mode.
- C. Reboot the SRX Series device to load the components.
- D. Restart the management daemon (mgd) to load the components.
Answer: B,C
Explanation:
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).

NEW QUESTION # 44
Which two statements are correct about the processing of NAT rules within a rule set? (Choose two.)
- A. NAT rules are processed from top to bottom.
- B. NAT rule processing processes all rules.
- C. NAT rule processing stops at the first match.
- D. NAT rules are processed from bottom to top.
Answer: A,C
Explanation:
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.

NEW QUESTION # 45
A new packet arrives on an interface on your SRX Series Firewall that is assigned to the trust security zone.
In this scenario, how does the SRX Series Firewall determine the egress security zone?
- A. by examining the destination port
- B. by performing a route lookup
- C. by performing a session lookup
- D. by examining the ingress security zone properties
Answer: B
Explanation:
When a new packet arrives that does not match an existing session, the SRX performs full flow-based processing. After ingress zone determination, the firewall must know the destination zone to evaluate security policies.
* The SRX determines theegress zone by performing a route lookupon the packet's destination IP address.
* The routing decision identifies the outgoing interface, and the zone associated with that interface becomes theegress zone.
* Session lookup (Option A) happens first but is only useful for existing sessions.
* Destination port (Option B) is used for application identification, not zone determination.
* Ingress zone properties (Option D) cannot determine the egress zone.

NEW QUESTION # 46
Which two statements are correct about security zones on an SRX Series device? (Choose two.)
- A. Intrazone and interzone traffic both require security policies.
- B. Security zones cannot be shared between routing instances.
- C. Multiple security zones cannot be configured on an SRX Series device.
- D. Security zones can be shared between routing instances.
Answer: A,B
Explanation:
* 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
Reference:Juniper Networks -Security Zones and Routing Instances, Junos OS Security Fundamentals.
NEW QUESTION # 47
You have a situation where legitimate traffic is incorrectly identified as malicious by your screen options.
In this scenario, what should you do?
- A. Discard the traffic immediately.
- B. Enable all screen options.
- C. Increase the sensitivity of the screen options.
- D. Use the alarm-without-drop configuration parameter.
Answer: D
Explanation:
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.

NEW QUESTION # 48
What are two system-defined zones created on the SRX Series Firewalls? (Choose two.)
- A. management
- B. junos-host
- C. null
- D. DMZ
Answer: B,C
Explanation:
On SRX Series Firewalls, Junos OS automatically createssystem-defined zonesthat have special functions:
* Null zone (Option A):A predefined discard zone. By default, all interfaces belong to the null zone until assigned to a user-defined zone. Traffic destined to the null zone is dropped.
* Junos-host zone (Option B):A predefined functional zone that allows security policies to control traffic directed to the SRX device itself (management traffic, such as SSH, HTTP, SNMP).
* Management zone (Option C):There is a predefinedmanagement functional zone, but it is not called
"management" as a system-defined security zone.
* DMZ (Option D):A DMZ zone must be explicitly created by the administrator, it is not system-defined.
Correct Zones:null, junos-host
Reference:Juniper Networks -Security Zones and Functional Zones, Junos OS Security Fundamentals.
NEW QUESTION # 49
What happens if no match is found in both zone-based and global security policies?
- A. The traffic is discarded by the default security policy.
- B. The traffic is redirected to a predefined safe zone.
- C. The traffic is allowed by default.
- D. The traffic is logged for further analysis.
Answer: A
Explanation:
SRX devices operate on adefault deny-all policyif no explicit match is found:
* If a packet does not match any configuredzone-basedorglobalpolicy, it is implicitly denied.
* The traffic is discarded silently by the default security policy (Option A).
* Option B:No predefined "safe zone" exists.
* Option C:Logging occurs only if explicitly configured; default deny does not automatically log traffic.
* Option D:Incorrect, since the firewall defaults to deny, not permit.
Correct Behavior:Traffic is discarded by the default security policy.
Reference:Juniper Networks -Security Policy Evaluation and Default Deny Behavior, Junos OS Security Fundamentals.
NEW QUESTION # 50
When traffic enters an interface, which two results does a route lookup determine? (Choose two.)
- A. ingress interface
- B. egress interface
- C. DNS name
- D. egress security zone
Answer: B,D
Explanation:
When a packet enters an SRX interface, aroute lookupis performed:
* It determines theegress interface(Option B) by checking the destination IP against the routing table.
* Once the egress interface is known, its associatedegress security zone(Option D) is also determined.
* Theingress interface (Option A)is already known when the packet arrives, so the route lookup does not determine it.
* DNS name (Option C):DNS is unrelated to routing lookups.
Correct Results:egress interface, egress security zone
Reference:Juniper Networks -Packet Flow and Route Lookup, Junos OS Security Fundamentals.
NEW QUESTION # 51
Which UI enables you to manage, monitor, and maintain multiple firewalls using a single interface?
- A. Juniper Secure Analytics
- B. Secure Connect
- C. Security Director
- D. Juniper Identity Management Service
Answer: C
Explanation:
* 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
Reference:Juniper Networks -Junos Space Security Director Overview, Junos OS Security Fundamentals.
NEW QUESTION # 52
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. default policy
- B. zone policy
- C. routing policy
- D. global policy
Answer: D
Explanation:
* 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
