Which two criteria should a zone-based security policy include? (Choose two.)
- A. a destination port
- B. an action
- C. zone context
- D. a source port
Answer: A,D
Explanation:
A security policy is a set of statements that controls traffic from a specified source to a specified destination using a specified service. A policy permits, denies, or tunnels specified types of traffic unidirectionally between two points.
Each policy consists of:
A unique name for the policy.
A from-zone and a to-zone, for example: user@host# set security policies from-zone untrust to-zone untrust A set of match criteria defining the conditions that must be satisfied to apply the policy rule. The match criteria are based on a source IP address, destination IP address, and applications. The user identity firewall provides greater granularity by including an additional tuple, source-identity, as part of the policy statement.
A set of actions to be performed in case of a match-permit, deny, or reject.
Accounting and auditing elements-counting, logging, or structured system logging.

Which two statements are correct about IPsec security associations? (Choose two.)
- A. IPsec security associations are established during IKE Phase 1 negotiations.
- B. IPsec security associations are unidirectional.
- C. IPsec security associations are bidirectional.
- D. IPsec security associations are established during IKE Phase 2 negotiations.
Answer: C,D
Explanation:
The two statements that are correct about IPsec security associations are that they are bidirectional and that they are established during IKE Phase 2 negotiations. IPsec security associations are bidirectional, meaning that they provide security for both incoming and outgoing traffic. IPsec security associations are established during IKE Phase 2 negotiations, which negotiates the security parameters and establishes the security association between the two peers. For more information, please refer to the Juniper Networks IPsec VPN Configuration Guide, which can be found on Juniper's website.

What is the main purpose of using screens on an SRX Series device?
- A. to provide an alternative interface into the CLI
- B. to provide information about traffic patterns traversing the network
- C. to provide multiple ports for accessing security zones
- D. to provide protection against common DoS attacks
Answer: D
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.

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

Answer: C
NEW QUESTION # 53
Screens on an SRX Series device protect against which two types of threats? (Choose two.)
- A. zero-day outbreaks
- B. malicious e-mail attachments
- C. IP spoofing
- D. ICMP flooding
Answer: C,D
Explanation:
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.

NEW QUESTION # 56
Which two statements about user-defined security zones are correct? (Choose two.)
- A. Users cannot share security zones between routing instances.
- B. User-defined security zones do not apply to transit traffic.
- C. Users can share security zones between routing instances.
- D. Users can configure multiple security zones.
Answer: C,D
Explanation:
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.
