Question No : 5

What are two functions of Juniper ATP Cloud? (Choose two.)

A.malware inspection
B.Web content filtering
C.DDoS protection
D.Geo IP feeds

정답:
Explanation:
Juniper Advanced Threat Prevention (ATP) Cloud is a security service that helps organizations protect against advanced threats by providing real-time threat intelligence and automated response capabilities. It combines a cloud-based threat intelligence platform with the security capabilities of Juniper Networks security devices to provide comprehensive protection against advanced threats. The two functions of Juniper ATP Cloud include malware inspection and Geo IP feeds. The malware inspection component provides real-time protection against known and unknown threats by analyzing suspicious files and determining if they are malicious. The Geo IP feeds provide a global view of IP addresses and their associated countries, allowing organizations to identify and block traffic from known malicious countries.

정답:

Question No : 7

Your company is adding IP cameras to your facility to increase physical security. You are asked to help protect these loT devices from becoming zombies in a DDoS attack.
Which Juniper ATP feature should you configure to accomplish this task?

A.IPsec
B.static NAT
C.allowlists
D.C&C feeds

정답:
Explanation:
Juniper ATP should be configured with C&C feeds that contain lists of malicious domains and IP addresses in order to prevent IP cameras from becoming zombies in a DDoS attack.
This is an important step to ensure that the IP cameras are protected from malicious requests - and thus, they will not be able to be used in any DDoS attacks against the facility.

Question No : 8

A.the IP address of the primary Gigabit Ethernet port
B.the IP address of the Network Time Protocol server
C.the CIDR address
D.the IP address of the device management port

정답:
Explanation:
J-Web is a web-based interface for configuring and managing Juniper devices. The management and loopback address configuration option in J-Web allows you to configure the IP address of the device management port, which is used to remotely access and manage the device.

Question No : 9

You need to collect the serial number of an SRX Series device to replace it.
Which command will accomplish this task?

A.show chassis hardware
B.show system information
C.show chassis firmware
D.show chassis environment

정답:
Explanation:
The correct command to collect the serial number of an SRX Series device is the show chassis hardware command [1]. This command will return the serial number of the device, along with other information about the device such as the model number, part number, and version.
This command is available in Junos OS. More information about the show chassis hardware command can be found in the Juniper Networks technical documentation here [1]: https://www.juniper.net/documentation/en_US/junos/topics/reference/command-summary/show-chassis-hardware.html.

Question No : 10

Which statement about service objects is correct?

A.All applications are predefined by Junos.
B.All applications are custom defined by the administrator.
C.All applications are either custom or Junos defined.
D.All applications in service objects are not available on the vSRX Series device.

정답:
Explanation:
"Service objects represent applications and services that can be assigned to a security policy rule. Applications and services can either be predefined by Junos software or custom defined by the administrator."

Question No : 13

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 traversing the network

정답:
Explanation:
The main purpose of using screens on an SRX Series device is to provide protection against common Denial of Service (DoS) attacks. Screens help prevent network resources from being exhausted or unavailable by filtering or blocking network traffic based on predefined rules. The screens are implemented as part of the firewall function on the SRX Series device, and they help protect against various types of DoS attacks, such as TCP SYN floods, ICMP floods, and UDP floods.

Question No : 14

Which feature would you use to protect clients connected to an SRX Series device from a SYN flood attack?

A.security policy
B.host inbound traffic
C.application layer gateway
D.screen option

정답:
Explanation:
A screen option in the SRX Series device can be used to protect clients connected to the device from a SYN flood attack. Screens are security measures that you can use to protect your network from various types of attacks, including SYN floods. A screen option specifies a set of rules to match against incoming packets, and it can take specific actions such as discarding, logging, or allowing the packets based on the rules.

Question No : 15

You want to verify the peer before IPsec tunnel establishment.
What would be used as a final check in this scenario?

A.traffic selector
B.perfect forward secrecy
C.st0 interfaces
D.proxy ID

정답:
Explanation:
The proxy ID is used as a final check to verify the peer before IPsec tunnel establishment. The proxy ID is a combination of local and remote subnet and protocol, and it is used to match the traffic that is to be encrypted. If the proxy IDs match between the two IPsec peers, the IPsec tunnel is established, and the traffic is encrypted.
