Exhibit

  1. The highlighted incident (arrow) shown in the exhibit shows a progression level of "Download" in the kill chain.
    What are two appropriate mitigation actions for the selected incident? (Choose two.)
  2. Immediate response required: Block malware IP addresses (download server or CnC server)
  3. Immediate response required: Wipe infected endpoint hosts.
  4. Immediate response required: Deploy IVP integration (if configured) to confirm if the endpoint has executed the malware and is infected.
  5. Not an urgent action: Use IVP to confirm if machine is infected.

Answer(s): A,C

Explanation:

The appropriate mitigation actions for the selected incident are to block malware IP addresses

(download server or CnC server) and to deploy IVP integration (if configured) to confirm if the endpoint has executed the malware and is infected. This is because the incident shows a progression level of "Download" in the kill chain, which means that the malware has been downloaded and is likely to be executed. Blocking the malware IP addresses can prevent further communication with the malicious server and stop the malware from receiving commands or exfiltrating data. Deploying IVP integration can help verify the infection status of the endpoint and provide additional information about the malware behavior and impact. IVP integration is an optional feature that allows the ATP Appliance to interact with third-party endpoint security solutions such as Carbon Black, Cylance, and CrowdStrike.

Exhibit



Referring to the exhibit, which three protocols will be allowed on the ge-0/0/5.0 interface? (Choose three.)

  1. IBGP
  2. OSPF
  3. IPsec
  4. DHCP
  5. NTP

Answer(s): B,D,E

Explanation:

The exhibit shows the output of the "show interfaces ge-0/0/5.0 extensive" command on an SRX Series device. The output includes a section called "Security" that lists the protocols that are allowed on the ge-0/0/5.0 interface. The protocols that are allowed on the ge-0/0/5.0 interface are:
OSPF
DHCP
NTP
It's important to notice that the output don't have IBGP, IPsec, so these protocols are not allowed on the ge-0/0/5.0 interface.



Exhibit



Referring to the exhibit, which type of NAT is being performed?

  1. Static NAT
  2. Destination NAT
  3. Persistent NAT
  4. Source NAT

Answer(s): D

Explanation:

Source NAT is a type of NAT that is used to translate the source IP address and port number of a packet. This is typically used to allow multiple devices on a private network to access the internet using a single public IP address. In the exhibit, we can see that the source IP address and port number of the packet are being translated from 10.10.10.2/61606 to 203.0.113.100/179. This is a clear indication that Source NAT is being performed.

Regarding IPsec CoS-based VPNs, what is the number of IPsec SAs associated with a peer based upon?

  1. The number of traffic selectors configured for the VPN.
  2. The number of CoS queues configured for the VPN.
  3. The number of classifiers configured for the VPN.
  4. The number of forwarding classes configured for the VPN.

Answer(s): D

Explanation:

In IPsec CoS-based VPNs, the number of IPsec Security Associations (SAs) associated with a peer is based on the number of forwarding classes configured for the VPN. The forwarding classes are used to classify and prioritize different types of traffic, such as voice and data traffic. Each forwarding class requires a separate IPsec SA to be established between the peers, in order to provide the appropriate level of security and quality of service for each type of traffic.



Which method does an SRX Series device in transparent mode use to learn about unknown devices in a network?

  1. LLDP-MED
  2. IGMP snooping
  3. RSTP
  4. packet flooding

Answer(s): D

Explanation:

The SRX Series device in transparent mode uses packet flooding to learn about unknown devices in a network. Packet flooding is a process wherein the device sends out packets to every device it knows about or suspects in the network.
When the packets are returned, the device can identify and classify the unknown devices in the network.
