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

The null zone allows the use of security policies to log dropped control plane traffic.

The functional zone is used to define the management interface on smaller SRX Series Firewalls.

A security zone processes intra-zone traffic without a security policy.

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

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

by installing a local NGWF server

by checking the file extensions of blocked content

by examining the content filtering policies

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

You want to use Avira Antivirus.
Which two actions should you perform to satisfy this requirement? (Choose two.)

Restart the management daemon (mgd) to load the components.

Enable the Avira engine in configuration mode.

Reboot the SRX Series device to load the components.

Enable the Avira engine in operational 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).

You must ensure that sessions can only be established from the external device.
Referring to the exhibit, which type of NAT is being performed?

destination NAT only

source NAT only

static PAT only

static NAT and source NAT

From the exhibit:
* The internal host (172.25.11.101) is located in theTrust zone.
* The external address (203.0.113.199/30) is used for communication with the ISP.
* The requirement is thatsessions can only be initiated from the external device(the ISP or untrust side) toward the internal host.
This requirement matches the behavior ofDestination NAT:
* Destination NAT only (Option A):Maps the external/public IP (203.0.113.199) to the internal/private IP (172.25.11.101). This allows inbound connections to be translated and sent to the internal host. The internal host cannot initiate outbound sessions, since the translation only applies to inbound traffic.
* Source NAT only (Option B):Used for outbound sessions from internal private IPs to the Internet.
This does not meet the requirement.
* Static PAT (Option C):Maps a single port of a public IP to a private IP/port. The exhibit does not indicate a port-based translation.
* Static NAT and source NAT (Option D):Would provide bidirectional communication, allowing sessions to be initiated in both directions. This contradicts the requirement.
Correct NAT Type:Destination NAT only

新しい質問 14
Which two security policies are installed by default on SRX 300 Series Firewalls? (Choose two.)

a security policy to allow all traffic from the untrust zone to the trust zone

a security policy to allow all traffic from the trust zone to the untrust zone

a security policy to allow all traffic from the management zone to the trust zone

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
Reference:Juniper Networks -Default Security Policies and Intra-zone Rules, Junos OS Security Fundamentals.

You are asked to enable trace options to debug the packet flow.
In this scenario, which flag would you configure at the [edit security flow traceoptions] hierarchy?

packet-dump

general

state

basic-datapath

Traceoptions in thesecurity flow hierarchyprovide debugging for how packets are processed in the flow module.
* The correct flag to capturedetailed packet-level debuggingispacket-dump (Option A). This outputs packet-level trace messages showing flow decisions, NAT processing, and policy matches.
* general (Option B):Provides basic flow trace information but not full packet inspection.
* state (Option C):Tracks flow state transitions, less detailed than packet-dump.
* basic-datapath (Option D):Provides high-level datapath debugging, not detailed flow troubleshooting.
Correct Flag:packet-dump

Referring to the exhibit, which two statements are correct about the traffic flow shown in the exhibit? (Choose two.)

There is no change to the original source IP address.

The original source IP address was translated to a new source IP address.

There is no change to the original destination IP address.

The original destination IP address was translated to a new destination IP address.

* Inbound Flow (before NAT):Source =10.20.30.40(internal private IP)Destination =203.0.113.1(public DNS server)
* Outbound Flow (after NAT):Source =192.0.2.1(translated IP)Destination =203.0.113.1(unchanged) Analysis:
* Thesource IP (10.20.30.40)was translated to192.0.2.1. This indicatesSource NATwas applied #Option B is correct.
* Thedestination IP changedbetween the inbound and outbound view. Inbound it was203.0.113.1, and outbound it is still203.0.113.1in appearance, but notice the reversal: the session entry shows it as the outbound “source” side. This confirmsDestination NAT translation has occurredfor return flow consistency #Option D is correct.
* Option A:Incorrect. The original source IP was indeed translated.
* Option C:Incorrect. The destination IP did change in the flow processing.
Correct Statements:
* The original source IP address was translated to a new source IP address.
* The original destination IP address was translated to a new destination IP address.

新しい質問 17
Which two statements are true about the NextGen Web Filtering (NGWF) feature on an SRX Series device?
(2つ選んでください)

The NGWF feature consults your local lists before consulting the Juniper cloud.

The NGWF feature does not require a license.

The NGWF feature requires a license.

The NGWF feature consults the Juniper cloud before consulting your local lists.

* License Requirement (Option B):NextGen Web Filtering (NGWF) is a licensed feature on SRX devices. Without a license, the service cannot operate.
* Local vs. Cloud Lists (Option C):NGWF checkslocal block/allow lists first. If the URL does not match locally, the request is then checked against the Juniper cloud database.
* Option A:Incorrect, since the cloud is only consulted if the URL is not in the local list.
* Option D:Incorrect, as NGWF requires a valid subscription/license.
Correct Statements:NGWF requires a license, and it checks local lists before cloud lookup.

新しい質問18
Your company is acquiring a smaller company that uses the same private address range that your company currently uses in its North America division. You have a limited number of public IP addresses to use for the acquisition. You want to allow the new acquisition’s users to connect to the existing services in North America.
Which two features would you enable on your SRX Series Firewall to accomplish this task? (Choose two.)

IDP

ナット

BGP

PAT

When two networks use the same private IP address ranges, conflicts occur. The solution is to use address translation techniques on the SRX:
* NAT (Network Address Translation):Translates private IP addresses to another IP range, enabling connectivity between overlapping private networks.
* PAT (Port Address Translation):Extends NAT by allowing multiple private IPs to share one or a few public IPs using different port numbers. This is especially useful when there is a limited pool of public IP addresses.
Other options:
* IDP (Option A):Intrusion Detection and Prevention, unrelated to address overlap.
* BGP (Option C):A routing protocol, but it does not solve overlapping IP addressing problems.
Correct Features:NAT and PAT
Reference:Juniper Networks -NAT and Address Overlap Solutions, Junos OS Security Fundamentals.

新しい質問 19
Which two statements about global security policies are correct? (Choose two.)

The from-zone and to-zone contexts are not required for a global security policy.

Global security policies require specific zone contexts.

Global policies are processed before zone-based security policies.

You can use both zone-based security policies and global security policies at the same time.

Global security policies extend the flexibility of policy enforcement across the SRX. They are not tied to specific source and destination zones:
* From-zone and to-zone contexts are not required(Option A). Global policies apply across all zones unless restricted by match conditions.
* Global security policies do not require specific zone contexts(Option B is incorrect).
* Global policies areprocessed after zone-based policies, not before. This means that zone-based security policies take precedence (Option C is incorrect).
* Administrators can configure bothzone-based security policies and global security policies at the same timeon the same device (Option D is correct).
This allows flexible designs where specific policies can be enforced by zone, while general policies can be applied globally without duplicating rules across multiple zones.
Reference:Juniper Networks -Junos OS Security Fundamentals, Global Security Policies.

新しい質問 20
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?

routing policy

default policy

zone policy

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
Reference:Juniper Networks -Global Security Policies vs Zone-Based Policies, Junos OS Security Fundamentals.

新しい質問21
You are troubleshooting first path traffic not passing through an SRX Series Firewall. You have determined that the traffic is ingressing and egressing the correct interfaces using a route lookup.
In this scenario, what is the next step in troubleshooting why the device may be dropping the traffic?

Verify that the interfaces are in the correct security zones.

Verify the routing protocol being used.

Verify that source NAT is occurring.

Verify that the correct ALG is being used.

After confirming correct routing:
* The next step is toverify security zone assignments (Option A). If interfaces are not correctly assigned to zones, traffic will not be evaluated against proper inter-zone or intra-zone security policies, causing drops.
* Option B:The routing protocol is irrelevant once the correct route lookup is confirmed.
* Option C:NAT is checked later in the flow, not the immediate next step after routing.
* Option D:ALG is only needed for specific applications (FTP, SIP), not general troubleshooting.
Correct Next Step:Verify that interfaces are assigned to the correct security zones.

新しい質問22
Which two statements are correct about unified security policies? (Choose two.)

Traffic that matches a unified policy will not be evaluated by traditional security policy.

Dynamic applications in unified security policies analyze traffic based on Layer 4 information.

Traffic that matches a traditional policy will not be evaluated by unified security policy.

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.

新しい質問23
When traffic enters an interface, which two results does a route lookup determine? (Choose two.)

ingress interface

egress interface

DNS name

egress security zone

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.

新しい質問24
What happens if no match is found in both zone-based and global security policies?

The traffic is discarded by the default security policy.

The traffic is redirected to a predefined safe zone.

The traffic is logged for further analysis.

The traffic is allowed by default.

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.

この展示物を参照し、正しい記述はどれか？

policy3 will be shadowed because it matches the same application as policy1.

None of the policies will be shadowed.

policy1 will be shadowed because it matches the same application as policy3.

policy2 will be shadowed because it matches the same application as policy1.

Juniper SRX evaluatessecurity policies in order, top to bottom. The first matching policy determines the action, and no further policies are evaluated. This behavior can lead toshadowed policiesif later policies match the same conditions as earlier ones.
From the exhibit:
* Policy1:Matches application junos-http and permits traffic.
* Policy2:Matches application junos-https and permits traffic.
* Policy3:Matches application junos-http again, but denies traffic.
Sincepolicy1already matches all HTTP traffic and permits it, traffic never reachespolicy3. This makespolicy3 shadowedbecause it has the same match condition as policy1 but is evaluated later in the list.
Other options:
* Policy1 is not shadowed because it is evaluated first.
* Policy2 is independent (application = HTTPS) and therefore unaffected.
* Only policy3 is shadowed by policy1.
Correct Statement:Policy3 will be shadowed because it matches the same application as policy1.
