NEW QUESTION # 44
Refer to the exhibit,
which two potential violations will generate alarm ? (Choose Two)
- A. the number of policy violations by a source network identifier
- B. the number of policy violation to an application within a specified period
- C. the ratio of policy violation traffic compared to accepted traffic.
- D. the number of policy violation by a destination TCP port
Answer: A,B
Explanation:
The exhibit shows a security policy configuration with a threshold of 1000 policy violations by a source network identifier and a threshold of 10 policy violations to an application within a specified period. If either of these thresholds are exceeded, an alarm will be generated. Therefore, the correct answer is A and D. The other options are incorrect because:
B) The ratio of policy violation traffic compared to accepted traffic is not a criterion for triggering an alarm.
The security policy configuration does not specify any ratio or percentage of policy violation traffic that would cause an alarm.
C) The number of policy violation by a destination TCP port is also not a criterion for triggering an alarm.
The security policy configuration does not specify any threshold or duration for policy violation by a destination TCP port.

NEW QUESTION # 61
you are connecting two remote sites to your corporate headquarters site. You must ensure that traffic passes corporate headquarter.
- A. a Layer 3 VPN with the corporate firewall acting as the hub device
- B. full mesh IPsec VPNs with tunnels between all sites
- C. a full mesh Layer 3 VPN with the BGP route reflector behind the corporate firewall device
- D. hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device
- E. In this scenario, which VPN should be used?
Answer: D
Explanation:
The most appropriate VPN topology when you need to ensure that all traffic from remote sites passes through the corporate headquarters would be a hub-and-spoke model. In this model, the corporate headquarters acts as the hub, and all remote sites (spokes) connect to it. This ensures that inter-site traffic goes through the headquarters, which can be important for security policy enforcement, logging, or other centralized services.
Hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device - This setup will ensure that all traffic from the remote sites is routed through the corporate headquarters, allowing centralized control and inspection of the traffic.
NEW QUESTION # 62

- D. Create a routing instance named default
Answer: C
NEW QUESTION # 63
Exhibit.
Referring to the exhibit, which two statements are true? (Choose two.)
- A. The c-1 TSYS can use security flow resources up to the system maximum.
- B. The c-1 TSYS cannot use any security flow resources.
- C. The c-1 TSYS has a reservation for the security flow resource.
- D. The c-1 TSYS has no reservation for the security flow resource.
Answer: A,C
Explanation:
The system security profile named sp-1 has designated resources for policies and zones with a maximum of 100 and a reservation of 50 each. For NAT with no port address translation (nat-nopat- address), there is a maximum of 115 and a reservation of 100, and for static NAT rules (nat-static-rule), there is a maximum of 125 with 100 reserved.
When considering tenant systems, the profile applied (sp-1) will dictate the resources available to the tenant system named c-1.
The c-1 TSYS has a reservation for the security flow resource. - This would be true if the 'security flow resource' refers to policies and zones since there are reservations made in the profile sp-1.
The c-1 TSYS can use security flow resources up to the system maximum. - This is generally true for any tenant system unless there are explicit limits set that are lower than the system maximum.
NEW QUESTION # 64
You are asked to deploy Juniper atp appliance in your network. You must ensure that incidents and alerts are sent to your SIEM.
In this scenario, which logging output format is supported?
- A. binay
- B. JSON
- C. WELF
- D. CEF
Answer: D
Explanation:
The Juniper ATP Appliance platform collects, inspects and analyzes advanced and stealthy web, file, and email-based threats that exploit and infiltrate client browsers, operating systems, emails and applications. Juniper ATP Appliance's detection of malicious attacks generates incident and event details that can be sent to connected SIEM platforms in CEF, LEEF or Syslog formats1. CEF (Common Event Format) is an open log management standard that improves the interoperability of security-related information from different vendors2. Juniper ATP Appliance supports CEF format for sending events and system audit notifications to SIEM servers. You can configure the CEF format in the Juniper ATP Appliance Central Manager WebUI Config > Notifications > SIEM Settings1. Therefore, the correct answer is C. CEF is a supported logging output format for Juniper ATP Appliance.
The other options are incorrect because:
A) WELF (WebTrends Enhanced Log Format) is a proprietary log format developed by WebTrends Corporation for web analytics3. Juniper ATP Appliance does not support WELF format for SIEM integration.
B) JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans and machines to read and write4. Juniper ATP Appliance supports JSON format for HTTP API results, but not for SIEM notifications1.
D) Binary is a numeric system that uses only two digits: 0 and 1. Binary is not a logging output format for Juniper ATP Appliance or any SIEM platform.
