質問 # 51
Which two services would an SRX Series device use to connect to an LDAP server for identity-aware security policies? (Choose two.)
正解:C、D
質問 # 52
Which two statements accurately describe the role of hashing in VPNs? (Choose two.)
正解:A、B
解説:
The correct answers are B and D. In VPN cryptography, hashing is used for authentication and integrity checking, not confidentiality. Juniper's IPsec documentation describes MD5 as producing a 128-bit hash, also called a digital signature or message digest, from a message of arbitrary length. It also describes SHA as producing a 160-bit hash from a message of arbitrary length. That directly supports option B because a hash function takes variable-length input and produces a fixed-size digest.
Option D is also correct because Juniper states that the resulting hash is used like a fingerprint of the input to verify content and source authenticity and integrity. Juniper's IPsec overview further explains that Junos compares the calculated message digest against the expected digest to verify that the message has not been tampered with.
Option A is wrong because hashing is not compression; it is one-way digest generation. Option C is wrong because encryption protects confidentiality, while hashing validates integrity and authenticity. In IPsec, algorithms such as AES, DES, and 3DES provide encryption, while MD5, SHA-1, and SHA-2 provide hashing/HMAC-based authentication. Reference topics: IPsec VPN, hashing, HMAC, MD5, SHA, message digest, data integrity.
質問 # 53
In Juniper high availability (HA) SRX Series device implementations, which interface will be used to exchange session state, configuration files, and ensure session continuity across nodes using the proprietary Trivial Network Protocol?
正解:D
解説:
The correct answer is A. fab. In SRX Series chassis clustering, the fabric interface, shown as fab0/fab1, is the data-plane HA link used between cluster nodes. Juniper states that SRX chassis clusters use the fabric interface for session synchronization and traffic forwarding, and that the fabric link synchronizes dynamic runtime state, including session-state objects created by NAT, ALG, authentication, and IPsec processing.
This is what enables stateful failover and session continuity when traffic processing moves between nodes.
Option B, fxp0, is wrong because fxp0 is the out-of-band management interface, not the chassis-cluster synchronization path. Option C, fxp1, is tempting but wrong for this question: fxp1 is the control-link interface used for control-plane cluster functions such as heartbeats and cluster control communication, not the main session-state synchronization path. Option D, swfab, is not the standard SRX chassis-cluster fabric interface name used for this function. Juniper's clustering configuration examples specifically define fab0 and fab1 as the interfaces used for the fabric connection and data-plane RTO/session synchronization.
質問 # 54
You want to show tabular data for operational mode commands.
In this scenario, which logging parameter will provide this function?
正解:D
解説:
The logging parameter that will provide the function of showing tabular data for operational mode commands is count. The count parameter displays the number of packets and bytes that match a security policy and the action taken by the policy. The count parameter can be used with the show security policies hit-count command to display the policy counters in a tabular format. The count parameter can also be used with the show security flow session command to display the session counters in a tabular format. Reference: = show security policies hit-count, show security flow session
質問 # 55
On which three Hypervisors is vSRX supported? (Choose three.)
正解:B、C、D
解説:
vSRX is a virtual firewall that runs as a software instance on a hypervisor. A hypervisor is a software layer that allows multiple virtual machines to run on a single physical host. vSRX supports three hypervisors: VMware ESXi, Hyper-V, and KVM. VMware ESXi is a hypervisor that runs on x86 servers and supports various operating systems and applications. Hyper-V is a hypervisor that runs on Windows Server and supports Windows and Linux virtual machines. KVM (Kernel-based Virtual Machine) is a hypervisor that runs on Linux and supports Linux, Windows, and other operating systems.
