Answer : A, D

The two statements about the configuration shown in the exhibit are correct are:

A) The remote IKE gateway IP address is 203.0.113.100. The exhibit shows that the address option under the gateway statement is set to 203.0.113.100, which specifies the IP address of the primary IKE gateway.The address option is used to configure the IP address or the hostname of the remote peer that has a static IP address1.

D) The remote peer is assigned a dynamic IP address. The exhibit shows that the dynamic option under the gateway statement is configured with various attributes, such as general-ikeid, ike-user-type, and user-at-hostname. The dynamic option is used to configure the identifier for the remote gateway with a dynamic IP address.The dynamic option also enables the SRX Series device to accept multiple connections from remote peers that have the same identifier2.

The other statements are incorrect because:

B) The local peer is not assigned a dynamic IP address, but a static IP address. The exhibit shows that the local-address option under the gateway statement is set to 192.0.2.100, which specifies the IP address of the local IKE gateway.The local-address option is used to configure the IP address of the local peer that has a static IP address1.

C) The local IKE gateway IP address is not 203.0.113.100, but 192.0.2.100, as explained above.

Referring to the exhibit, your company's infrastructure team implemented new printers. To make sure that the policy enforcer pushes the updated IP address list to the SRX, you need to perform the following actions:

A) Configure the server feed URL as http://172.25.10.254/myprinters. The server feed URL is the address of the remote server that provides the custom feed data. You need to configure the server feed URL to match the location of the file that contains the IP addresses of the new printers.In this case, the file name is myprinters and the server IP address is 172.25.10.254, so the server feed URL should be http://172.25.10.254/myprinters1.

B) Create a security policy that uses the dynamic address feed to allow access. A security policy is a rule that defines the action to be taken for the traffic that matches the specified criteria, such as source and destination addresses, zones, protocols, ports, and applications. You need to create a security policy that uses the dynamic address feed as the source or destination address to allow access to the new printers. A dynamic address feed is a custom feed that contains a group of IP addresses that can be entered manually or imported from external sources.The dynamic address feed can be used in security policies to either deny or allow traffic based on either source or destination IP criteria2.

C) Configure Security Director to create a dynamic address feed. Security Director is a Junos Space application that enables you to create and manage security policies and objects. You need to configure Security Director to create a dynamic address feed that contains the IP addresses of the new printers. You can create a dynamic address feed by using the local file or the remote file server option.In this case, you should use the remote file server option and specify the server feed URL as http://172.25.10.254/myprinters3.

The other options are incorrect because:

D) Configuring Security Director to create a C&C feed is not required to complete the requirement. A C&C feed is a security intelligence feed that contains the IP addresses of servers that are used by malware or attackers to communicate with infected hosts. The C&C feed is not related to the new printers or the dynamic address feed.

E) Configuring the server feed URL as https://172.25.10.254/myprinters is not required to complete the requirement. The server feed URL can use either the HTTP or the HTTPS protocol, depending on the configuration of the remote server.In this case, the exhibit shows that the remote server is using the HTTP protocol, so the server feed URL should use the same protocol1.

Answer : A

The security feature that bypasses routing or switching lookup is transparent mode. The other options are incorrect because:

B) Secure wire is a feature that allows you to connect two interfaces on the same device and forward traffic between them without any processing.Secure wire does not bypass routing or switching lookup, but rather eliminates them altogether1.

C) Mixed mode is a mode of operation for SRX Series devices that allows you to configure both transparent mode and switching mode on the same device.Mixed mode does not bypass routing or switching lookup, but rather uses them depending on the interface type2.

D) MACsec (Media Access Control Security) is a feature that provides encryption and authentication for Layer 2 traffic.MACsec does not bypass routing or switching lookup, but rather operates at a lower layer3.

Therefore, the correct answer is

A) Transparent mode is a mode of operation for SRX Series devices that provides Layer 2 bridging capabilities with full security services. In transparent mode, the SRX Series device acts as a bridge between two network segments and inspects the packets without modifying the source or destination information in the IP packet header. The SRX Series device does not have an IP address in transparent mode, except for the management interface.Transparent mode bypasses routing or switching lookup, because the SRX Series device does not perform any routing or switching functions, but rather forwards the packets based on the MAC addresses4.

The two security intelligence feed types that are supported are:

A) Infected host feed. An infected host feed is a security intelligence feed that contains the IP addresses of hosts that are infected by malware or compromised by attackers. The SRX Series device can download the infected host feed from the Juniper ATP Cloud or generate its own infected host feed based on the detection events from IDP.The SRX Series device can use the infected host feed to block or quarantine the traffic to or from the infected hosts based on the security policies1.

B) Command and Control feed. A command and control feed is a security intelligence feed that contains the IP addresses of servers that are used by malware or attackers to communicate with infected hosts. The SRX Series device can download the command and control feed from the Juniper ATP Cloud or generate its own command and control feed based on the detection events from IDP.The SRX Series device can use the command and control feed to block or log the traffic to or from the command and control servers based on the security policies2.

The other options are incorrect because:

C) Custom feeds. Custom feeds are not a security intelligence feed type, but a feature that allows you to create your own security intelligence feeds based on your own criteria and sources. You can configure custom feeds by using the Junos Space Security Director or the CLI.Custom feeds are not supported by the Juniper ATP Cloud or the IDP3.

D) Malicious URL feed. Malicious URL feed is not a security intelligence feed type, but a feature that allows you to block or log the traffic to or from malicious URLs based on the security policies. The SRX Series device can download the malicious URL feed from the Juniper ATP Cloud or the Juniper Threat Labs.Malicious URL feed is not supported by the IDP4.

Referring to the exhibit, the following statements are correct:

B) All of the entries are command and control entries. Command and control entries are dynamic addresses that represent the IP addresses of servers that are used by malware to communicate with infected hosts. The SRX Series device can block or log the traffic to or from these IP addresses based on the security policies.The exhibit shows that all of the entries have the category DC/1, which stands for command and control1.

C) All of the entries are Dshield entries. Dshield is a feed source that provides a list of IP addresses that are associated with malicious activities, such as scanning, spamming, or attacking. The SRX Series device can download the Dshield feed and use it to populate the dynamic address entries.The exhibit shows that all of the entries have the feed dshield, which indicates that they are from the Dshield feed source2.

The other statements are incorrect because:

A) All of the entries are not a threat level 8, but a threat level 10. The threat level is a numeric value that indicates the severity of the threat associated with a dynamic address entry. The higher the threat level, the more dangerous the threat. The SRX Series device can use the threat level to prioritize the actions for the dynamic address entries. The exhibit shows that all of the entries have the cc CN, which stands for country code China. According to the Juniper documentation, the country code China has a threat level of 10, which is the highest.

D) All of the entries are not a threat level 10, but they are. See the explanation for option A.
