What is the default value of the dead peer detection (DPD) interval for an IPsec VPN tunnel?
- A. 10 seconds
- B. 40 seconds
- C. 20 seconds
- D. 5 seconds
Answer: D
Explanation:
The default value of the dead peer detection (DPD) interval for an IPsec VPN tunnel is 5 seconds. DPD is a mechanism that enables the IPsec device to detect if the peer is still reachable or if the IPsec VPN tunnel is still active. The DPD interval determines how often the IPsec device sends DPD packets to the peer to check the status of the VPN tunnel. A value of 5 seconds is a common default, but the specific value can vary depending on the IPsec device and its configuration.

NEW QUESTION # 35
Which two user authentication methods are supported when using a Juniper Secure Connect VPN? (Choose two.)
- A. multi-factor authentication
- B. local authentication
- C. certificate-based
- D. active directory
Answer: B,D
Explanation:
"Local Authentication-In local authentication, the SRX Series device validates the user credentials by checking them in the local database. In this method, the administrator handles change of password or resetting of forgotten password. Here, it requires that an user must remember a new password. This option is not much preferred from a security standpoint.
* External Authentication-In external authentication, you can allow the users to use the same user credentials they use when accessing other resources on the network. In many cases, user credentials are domain logon used for Active Directory or any other LDAP authorization system. This method simplifies user experience and improves the organization's security posture; because you can maintain the authorization system with the regular security policy used by your organization."
