NEW QUESTION 1
You have deployed an SRX300 Series device and determined that files have stopped being scanned. In this scenario, what is a reason for this problem?

A.    The software license is a free model and only scans executable type files.
B.    The infected host communicated with a command-and-control server, but it did not download malware.
C.    The file is too small to have a virus.
D.    You have exceeded the maximum files submission for your SRX platform size.

Answer: D
Explanation:
D is correct because file scanning on SRX300 Series device has a limit on the number of files that can be submitted per minute based on the platform size. For example, SRX320 has a limit of 10 files per minute.

NEW QUESTION 2
Which two statements are correct about security policy changes when using the policy rematch feature? (Choose two.)

A.    When a policy change includes changing the policy’s action from permit to deny, all existing sessions are maintained.
B.    When a policy change includes changing the policy’s source or destination address match condition, all existing sessions are dropped.
C.    When a policy change includes changing the policy’s action from permit to deny, all existing sessions are dropped.
D.    When a policy change includes changing the policy’s source or destination address match condition, all existing sessions are reevaluated.

Answer: CD
Explanation:
Policy rematch is a feature that enables the device to reevaluate an active session when its associated security policy is modified. The session remains open if it still matches the policy that allowed the session initially. The session is closed if its associated policy is renamed, deactivated, or deleted.

NEW QUESTION 3
Which two statements are true about the vSRX? (Choose two.)

A.    It does not have VMXNET3 vNIC support.
B.    It has VMXNET3 vNIC support.
C.    UNIX is the base OS.
D.    Linux is the base OS.

Answer: BD
Explanation:
1. The vSRX is a virtual security appliance that runs on a virtual machine. It provides firewall, VPN, and other security services in a virtualized environment.
2. The vSRX is based on a version of Junos OS that is optimized for virtualization. It runs on a Linux kernel and uses a KVM hypervisor. It supports VMware ESXi and KVM hypervisors.
3. The vSRX has support for VMXNET3 vNICs, which are high-performance virtual network interfaces provided by VMware. These interfaces can provide higher throughput and lower CPU utilization than other virtual NIC types.

NEW QUESTION 4
You want to manually failover the primary Routing Engine in an SRX Series high availability cluster pair. Which step is necessary to accomplish this task?

A.    Issue the set chassis cluster disable reboot command on the primary node.
B.    Implement the control link recover/ solution before adjusting the priorities.
C.    Manually request the failover and identify the secondary node.
D.    Adjust the priority in the configuration on the secondary node.

Answer: A
Explanation:
In order to manually failover the primary Routing Engine in an SRX Series high availability cluster pair, you must issue the command “set chassis cluster disable reboot” on the primary node. This command will disable the cluster and then reboot the primary node, causing the secondary node to take over as the primary node.

NEW QUESTION 5
Your manager asks you to provide firewall and NAT services in a private cloud. Which two solutions will fulfill the minimum requirements for this deployment? (Choose two.)

A.    a single vSRX
B.    a vSRX for firewall services and a separate vSRX for NAT services
C.    a cSRX for firewall services and a separate cSRX for NAT services
D.    a single cSRX

Answer: BC
Explanation:
A single vSRX or cSRX cannot provide both firewall and NAT services simultaneously. To meet the minimum requirements for this deployment, you need to deploy a vSRX for firewall services and a separate vSRX for NAT services (option B), or a cSRX for firewall services and a separate cSRX for NAT services (option C).

NEW QUESTION 6
You enable chassis clustering on two devices and assign a cluster ID and a node ID to each device. In this scenario, what is the correct order for rebooting the devices?

A.    Reboot the secondary device, then the primary device.
B.    Reboot only the secondary device since the primary will assign itself the correct cluster and node ID.
C.    Reboot the primary device, then the secondary device.
D.    Reboot only the primary device since the secondary will assign itself the correct cluster and node ID.

Answer: C
Explanation:
When enabling chassis clustering on two devices, the correct order for rebooting them is to reboot the primary device first, followed by the secondary device. It is not possible for either device to assign itself the correct cluster and node ID, so both devices must be rebooted to ensure the proper configuration is applied.

NEW QUESTION 7
You want to deploy a virtualized SRX in your environment. In this scenario, why would you use a vSRX instead of a cSRX? (Choose two.)

A.    The vSRX supports Layer 2 and Layer 3 configurations.
B.    Only the vSRX provides clustering.
C.    The vSRX has faster boot times.
D.    Only the vSRX provides NAT, IPS, and UTM services.

Answer: AC
Explanation:
The vSRX supports both Layer 2 and Layer 3 configurations, while the cSRX is limited to Layer 3 configurations. Additionally, the vSRX has faster boot times, which is advantageous in certain scenarios. The vSRX and cSRX both provide NAT, IPS, and UTM services.

NEW QUESTION 8
Which two statements are true about the fab interface in a chassis cluster? (Choose two.)

A.    The fab link does not support fragmentation.
B.    The physical interface for the fab link must be specified in the configuration.
C.    The fab link supports traditional interface features.
D.    The Junos OS supports only one fab link.

Answer: BC
Explanation:
The physical interface for the fab link must be specified in the configuration. Additionally, the fab link supports traditional interface features such as MAC learning, security policy enforcement, and dynamic routing protocols. The fab link does not support fragmentation and the Junos OS supports up to two fab links.

NEW QUESTION 9
After JSA receives external events and flows, which two steps occur? (Choose two.)

A.    After formatting the data, the data is stored in an asset database.
B.    Before formatting the data, the data is analyzed for relevant information.
C.    Before the information is filtered, the information is formatted.
D.    After the information is filtered, JSA responds with active measures.

Answer: BC
Explanation:
Before formatting the data, the data is analyzed for relevant information. This is done to filter out any irrelevant data and to extract any useful information from the data. After the information is filtered, it is then formatted so that it can be stored in an asset database. After the data has been formatted, JSA will then respond with active measures.

NEW QUESTION 10
Which two statements are correct about chassis clustering? (Choose two.)

A.    The node ID value ranges from 1 to 255.
B.    The node ID is used to identify each device in the chassis cluster.
C.    A system reboot is required to activate changes to the cluster.
D.    The cluster ID is used to identify each device in the chassis cluster.

Answer: AB
Explanation:
The node ID value ranges from 1 to 255 and is used to identify each device in the chassis cluster. The cluster ID is also used to identify each device, but it is not part of the node ID configuration. A system reboot is not required to activate changes to the cluster, but it is recommended to ensure that all changes are applied properly.

NEW QUESTION 11

Explanation:
The AppFW module in the AppSecure suite provides IPS signatures that can be used to monitor traffic and detect malicious activities. AppFW also provides other security controls such as Web application firewall, URL filtering, and application-level visibility.

NEW QUESTION 12
Which two statements are correct about JSA data collection? (Choose two.)

A.    The Event Collector collects information using BGP FlowSpec.
B.    The Flow Collector can use statistical sampling.
C.    The Flow Collector parses logs.
D.    The Event Collector parses logs.

Answer: BD
Explanation:
The Flow Collector can use statistical sampling to collect and store network flow data in the JSA database. The Event Collector collects information from various sources including syslog, SNMP, NetFlow, and BGP FlowSpec. Both the Flow Collector and the Event Collector parse logs to extract useful information from the logs.

NEW QUESTION 13
You are configuring logging for a security policy. In this scenario, in which two situations would log entries be generated? (Choose two.)

A.    every 10 minutes
B.    at session initialization
C.    every 60 seconds
D.    at session close

Answer: BD
Explanation:
Log entries would be generated in two situations: at session initialization and at session close. At session initialization, the log entry would include details about the connection, such as the source and destination IP addresses, the service being used, and the action taken by the security policy. At session close, the log entry would include details about the connection, such as the duration of the session, the bytes sent/received, and the action taken by the security policy.

NEW QUESTION 14
Which two statements are true about Juniper ATP Cloud? (Choose two.)

A.    Dynamic analysis is always performed to determine if a file contains malware.
B.    If the cache lookup determines that a file contains malware, performed to verify the results.
C.    Dynamic analysis is not always necessary to determine if a file contains malware.
D.    If the cache lookup determines that a file contains malware, static analysis is not performed to verify the results.

Answer: BC
Explanation:
B: If the cache lookup determines that a file contains malware, dynamic analysis is still performed to verify the results and ensure that no new or previously unknown malware behavior is present. This is because malware can be designed to evade detection by security systems, and dynamic analysis can help to detect such behavior. By performing dynamic analysis even for files that are found in the cache and are already known to be malicious, Juniper ATP Cloud can provide a more comprehensive and accurate assessment of potential threats.
C: Dynamic analysis is not always necessary to determine if a file contains malware, as the ATP Cloud uses a cache lookup to quickly identify known malicious files.

NEW QUESTION 15
You are asked to create an IPS-exempt rule base to eliminate false positives from happening. Which two configuration parameters are available to exclude traffic from being examined? (Choose two.)

A.    source port
B.    source IP address
C.    destination IP address
D.    destination port

Answer: BD
Explanation:
To exclude traffic from being examined by IPS, you can use the source IP address and/or destination port as criteria for the exemption. This is achieved by configuring an IPS-exempt rule base that includes specific exemption rules based on these criteria.

NEW QUESTION 16
What are three capabilities of AppQoS? (Choose three.)

A.    re-write DSCP values
B.    assign a forwarding class
C.    re-write the TTL
D.    rate-limit traffic
E.    reserve bandwidth

Answer: ABE
Explanation:
AppQoS (Application Quality of Service) is a Junos OS feature that provides advanced control and prioritization of application traffic. With AppQoS, you can classify application traffic, assign a forwarding class to the traffic, and apply quality of service (QoS) policies to the traffic. You can also re-write DSCP values and reserve bandwidth for important applications. However, AppQoS does not re-write the TTL or rate-limit traffic.

NEW QUESTION 17
Which two sources are used by Juniper Identity Management Service (JIMS) for collecting username and device IP addresses? (Choose two.)

A.    Microsoft Exchange Server event logs.
B.    DNS.
C.    Active Directory domain controller event logs.
D.    OpenLDAP service ports.

Answer: BC
Explanation:
Juniper Identity Management Service (JIMS) collects username and device IP addresses from both DNS and Active Directory domain controller event logs. DNS is used to resolve hostnames to IP addresses, while Active Directory domain controller event logs are used to get information about user accounts, such as when they last logged in.

NEW QUESTION 18
Which two devices would you use for DDoS protection with Policy Enforcer? (Choose two.)

A.    vQFX
B.    MX
C.    vMX
D.    QFX

Answer: BC
Explanation:
The MX and vMX devices can be used for DDoS protection with Policy Enforcer. Policy Enforcer is a Juniper Networks solution that provides real-time protection from DDoS attacks. It can be used to detect and block malicious traffic, and also provides granular control over user access and policy enforcement. The MX and vMX devices are well-suited for use with Policy Enforcer due to their high-performance hardware and advanced security features.

NEW QUESTION 19
What are two types of system logs that Junos generates? (Choose two.)

A.    SQL log files.
B.    data plane logs.
C.    system core dump files.
D.    control plane logs.

Answer: BD
Explanation:
The two types of system logs that Junos generates are control plane logs and data plane logs. Control plane logs are generated by the Junos operating system and contain system-level events such as system startup and shutdown, configuration changes, and system alarms. Data plane logs are generated by the network protocol processes and contain messages about the status of the network and its components, such as routing, firewall, NAT, and IPS. SQL log files and system core dump files are not types of system logs generated by Junos.
