QUESTION 51
Referring to the exhibit.

Which type of NAT is being performed?

Source NAT with PAT

Source NAT without PAT

Destination NAT without PAT

Destination NAT with PAT

QUESTION 52
Which statement about global NAT address persistence is correct?

The same IP address from a source NAT pool will be assigned for all sessions from a given host.

The same IP address from a source NAT pool is not guaranteed to be assigned for all sessions from a given host.

The same IP address from a destination NAT pool will be assigned for all sessions for a given host.

The same IP address from a destination NAT pool is not guaranteed to be assigned for all sessions for a given host.

Use the persistent-nat feature to ensure that all requests from the same internal transport address are mapped to the same reflexive transport address (the public IP address and port created by the NAT device closest to the STUN server). The source NAT rule action can use a source NAT pool (with or without port translation) or an egress interface.

QUESTION 53
Which two statements about user-defined security zones are correct? (Choose two.)

Users cannot share security zones between routing instances.

Users can configure multiple security zones.

Users can share security zones between routing instances.

User-defined security zones do not apply to transit traffic.

User-defined security zones allow users to configure multiple security zones and share them between routing instances. This allows users to easily manage multiple security zones and their associated policies. For example, a user can create a security zone for corporate traffic, a security zone for guest traffic, and a security zone for public traffic, and then configure policies to control the flow of traffic between each of these security zones. Transit traffic can also be managed using user-defined security zones, as the policies applied to these zones will be applied to the transit traffic as well.

QUESTION 54
Screens on an SRX Series device protect against which two types of threats? (Choose two.)

IP spoofing

ICMP flooding

zero-day outbreaks

malicious e-mail attachments

ICMP flood
Use the ICMP flood IDS option to protect against ICMP flood attacks. An ICMP flood attack typically occurs when ICMP echo requests use all resources in responding, such that valid network traffic can no longer be processed.
The threshold value defines the number of ICMP packets per second (pps) allowed to be send to the same destination address before the device rejects further ICMP packets.
IP spoofing
Use the IP address spoofing IDS option to prevent spoofing attacks. IP spoofing occurs when an invalid source address is inserted in the packet header to make the packet appear to come from a trusted source.

QUESTION 55
You must monitor security policies on SRX Series devices dispersed throughout locations in your organization using a ‘single pane of glass’ cloud-based solution.
Which solution satisfies the requirement?

Juniper Sky Enterprise

J-Web

Junos Secure Connect

Junos Space

Junos Space is a management platform that provides a single pane of glass view of SRX Series devices dispersed throughout locations in your organization. It provides visibility into the security policies of the devices, allowing you to quickly identify and respond to security threats. Additionally, it provides the ability to manage multiple devices remotely and in real-time, enabling you to quickly deploy and update security policies on all devices. For more information, please refer to the Juniper Networks Junos Space Network Director User Guide, which can be found on Juniper’s website.

QUESTION 56
Which two statements are correct about global policies? (Choose two.)

Global policies are evaluated after default policies.

Global policies do not have to reference zone context.

Global policies are evaluated before default policies.

Global policies must reference zone contexts.

Global policies are used to define rules for traffic that is not associated with any particular zone. This type of policy is evaluated first, before any rules related to specific zones are evaluated.
For more detailed information about global policies, refer to the Juniper Networks Security Policy Overview guide, which can be found at https://www.juniper.net/documentation/en_US/junos/topics/reference/security-policy-overview.html. The guide provides an overview of the Juniper Networks security policy architecture, as well as detailed descriptions of the different types of policies and how they are evaluated.

QUESTION 57
Which two match conditions would be used in both static NAT and destination NAT rule sets? (Choose two.)

Destination zone

Destination interface

Source interface

Source zone

QUESTION 58
Which two addresses are valid address book entries? (Choose two.)

173.145.5.21/255.255.255.0

153.146.0.145/255.255.0.255

203.150.108.10/24

191.168.203.0/24

The correct address book entries are:
173.145.5.21/255.255.255.0
203.150.108.10/24
Both of these entries represent a valid IP address and subnet mask combination, which can be used as an address book entry in a Juniper device.

QUESTION 59
On an SRX device, you want to regulate traffic base on network segments.
In this scenario, what do you configure to accomplish this task?

Screens

Zones

ALGs

NAT

QUESTION 60
Click the Exhibit button.

You are asked to allow only ping and SSH access to the security policies shown in the exhibit.
Which statement will accomplish this task?

Rename policy Rule-2 to policy Rule-0.

Insert policy Rule-2 before policy Rule-1.

Replace application any with application [junos-ping junos-ssh] in policy Rule-1.

Rename policy Rule-1 to policy Rule-3.

QUESTION 61
You want to prevent other users from modifying or discarding your changes while you are also editing the configuration file.
In this scenario, which command would accomplish this task?

configure master

cli privileged

configure exclusive

configure

QUESTION 62
When are Unified Threat Management services performed in a packet flow?

before security policies are evaluated

as the packet enters an SRX Series device

only during the first path process

after network address translation

QUESTION 63
Which two statements are correct about security zones? (choose two)

Security zones use packet filters to prevent communication between management ports

Security zones use security policies that enforce rules for the transit traffic
