interface media type -> system slot number -> line card slot number -> port number

interface media type -> port number -> system slot number -> line card slot number

Q19. Which two IPsec hashing algorithms are supported on an SRX Series device? (Choose two.)

SHA-1

SHAKE128

MD5

RIPEMD-256

Q20. Which two statements are correct about the integrated user firewall feature?(Choose two.)

It maps IP addresses to individual users.

It supports IPv4 addresses.

It allows tracking of non-Windows Active Directory users.

It uses the LDAP protocol.

Q21. Which feature would you use to protect clients connected to an SRX Series device from a SYN flood attack?

security policy

host inbound traffic

application layer gateway

screen option

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.

Q25. Which statement about NAT is correct?

Destination NAT takes precedence over static NAT.

Source NAT is processed before security policy lookup.

Static NAT is processed after forwarding lookup.

Static NAT takes precedence over destination NAT.

Q26. You are assigned a project to configure SRX Series devices to allow connections to your webservers. The webservers have a private IP address, and the packets must use NAT to be accessible from the Internet. The webservers must use the same address for both connections from the Internet and communication with update servers.
Which NAT type must be used to complete this project?

source NAT

destination NAT

static NAT

hairpin NAT

Only static NAT with pool ensures both traffic initiated from inside and outside networks use the same IP address.

Q27. Which two statements are correct about functional zones? (Choose two.)

A functional zone uses security policies to enforce rules for transit traffic.

Traffic received on the management interface in the functional zone cannot transit out other interface.

Functional zones separate groups of users based on their function.

A function is used for special purpose, such as management interface

Q28. Which two user authentication methods are supported when using a Juniper Secure Connect VPN? (Choose two.)

certificate-based

multi-factor authentication

local authentication

active directory

“Local Authentication-In local authentication, the SRX Series device validates the user credentials by checking them in the local database. In this method, the administrator handles change of password or resetting of forgotten password. Here, it requires that an user must remember a new password. This option is not much preferred from a security standpoint.
* External Authentication-In external authentication, you can allow the users to use the same user credentials they use when accessing other resources on the network. In many cases, user credentials are domain logon used for Active Directory or any other LDAP authorization system. This method simplifies user experience and improves the organization’s security posture; because you can maintain the authorization system with the regular security policy used by your organization.”

The most restrictive policy is applied regardless of the policy level.

A global policy is always evaluated first.

The first policy rule is applied regardless of the policy level.

Q31. Which statements describes stateless firewalls on SRX series devices?

Each packet is analyzed by firewall filters

Each packet is analyzed based on application layer security

Each packet is analyzed based on source zone

Each packet is analyzed as part of a session.

Q32. You have configured a Web filtering UTM policy?
Which action must be performed before the Web filtering UTM policy takes effect?

The UTM policy must be linked to an egress interface

The UTM policy be configured as a routing next hop.

The UTM policy must be linked to an ingress interface.

The UTM policy must be linked to a security policy
