NEW QUESTION # 42
Exhibit
You configure a traceoptions file called radius on your returns the output shown in the exhibit What is the source of the problem?
- A. The RADIUS server suffered a hardware failure.
- B. An incorrect password is being used.
- C. The authentication order is misconfigured.
- D. The RADIUS server IP address is unreachable.
Answer: B
Explanation:
According to the output of the traceoptions file called radius, the source of the problem is that the RADIUS server IP address is unreachable. This is indicated by the line FAILURE: sendto: No route to host, which shows that the SRX device cannot send the authentication request to the RADIUS server. This could be due to a network issue, such as a misconfigured route, a firewall blocking the traffic, or a physical link failure.
To troubleshoot this issue, the user should check the following:
The RADIUS server IP address and port are correctly configured on the SRX device. The user can verify this by using the command show configuration access radius-server1.
The SRX device can ping the RADIUS server IP address. The user can use the command ping <RADIUS-server-IP> to test the connectivity2.
The SRX device has a valid route to the RADIUS server IP address. The user can use the command show route <RADIUS-server-IP> to check the routing table3.
The SRX device and the RADIUS server are using the same shared secret key. The user can verify this by using the command show configuration access radius-server secret1.
The SRX device and the RADIUS server are using the same authentication protocol. The user can verify this by using the command show configuration access profile <profile-name>4.
The firewall policies on the SRX device and any intermediate devices are allowing the RADIUS traffic. The user can use the command show security policies from-zone <source-zone> to-zone <destination-zone> to check the firewall policies5.
NEW QUESTION # 43
Which statement is true about persistent NAT types?
- A. The target-host-port parameter cannot be used with IPv4 addresses in NAT46.
- B. The target-host parameter cannot be used with IPv6 addressee in NAT64.
- C. The target-host-port parameter cannot be used with IPv6 addresses in NAT64
- D. The target-host parameter cannot be used with IPv4 addresses in NAT46
Answer: C
Explanation:
NAT (Network Address Translation) is a method to map one IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. There are different types of NAT, one of them is the persistent NAT which is a type of NAT that allows you to map the same internal IP address to the same external IP address each time a host initiates a connection.

NEW QUESTION # 49
Exhibit:
Referring to the exhibit, which two statements are correct?
- A. All of the entries are Dshield entries
- B. All of the entries are a threat level 10.
- C. All of the entries are command and control entries.
- D. All of the entries are a threat level 8
Answer: A,C
Explanation:
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.

NEW QUESTION # 55
Exhibit
You are using trace options to verity NAT session information on your SRX Series device Referring to the exhibit, which two statements are correct? (Choose two.)
- A. This packet is part of an existing session.
- B. The SRX device is changing the destination address on this packet 10.0.1 1 to 172 20.101.10.
- C. This is the first packet in the session
- D. The SRX device is changing the source address on this packet from
Answer: A,B
Explanation:
According to the trace options output in the exhibit, the following statements are correct:
This packet is part of an existing session. This is indicated by the line flow session id 0x00000000, hash 0x00000000, table 0x00000000, flow process exit, which shows that the packet matches an existing session entry in the flow table1.
The SRX device is changing the destination address on this packet from 10.0.1.1 to 172.20.101.10. This is indicated by the line nat: translated 10.0.1.1->172.20.101.10, which shows that the packet undergoes destination NAT2.
The following statements are incorrect:
The SRX device is changing the source address on this packet. There is no indication of source NAT in the trace options output2.
This is the first packet in the session. The first packet in a session would have a different trace options output, which would include the line flow_first_inline_processing and show the creation of a new session entry in the flow table1.
NEW QUESTION # 56
Exhibit

- A. Modify the security policy to allow the BGP traffic.
- B. Configure destination NAT for BGP traffic.
- C. Create a firewall filter to accept the BGP traffic
- D. Add BGP to the Allowed host-inbound-traffic for the interface
Answer: C

NEW QUESTION # 60
which security feature bypasses routing or switching lookup?
- A. MACsec
- B. secure wire
- C. mixed mode
- D. transparent mode
Answer: D
Explanation:
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.
