質問 # 59
Exhibit:
Referring to the exhibit, which route will be selected for a packet destined to IP address 10.50.10.55?
正解：B
解説：
In Junos OS, the Routing Information Base (RIB) selection process follows a strict hierarchy where the Longest Prefix Match (LPM) is the absolute primary tie-breaker. When a packet is destined for 10.50.10.55
, the Routing Engine searches the inet.0 table for all matching entries. In this exhibit, four routes match: the default route ( 0.0.0.0/0 ), a general static route ( 10.0.0.0/8 ), an OSPF route ( 10.50.0.0/16 ), and a BGP route ( 10.50.10.0/24 ).
The LPM rule dictates that the router must select the most specific route available, which is defined as the entry with the highest number of matching bits in the subnet mask. The 10.50.10.0/24 route matches 24 bits of the destination address, making it more specific than the 16-bit, 8-bit, or 0-bit alternatives. It is critical to understand that route preference (e.g., Static at 5, OSPF at 10, or BGP at 170) is only evaluated if there are multiple paths to the exact same prefix and length. Because these prefixes vary in length, the length takes precedence over the protocol preference. Therefore, the BGP-learned route via 192.168.1.20 is selected as the active path, ensuring traffic follows the most granular routing information provided to the device. Reference:

質問 # 60
Click the Exhibit button.
Referring the exhibit, what does the highlighted number indicate?
正解：A
解説：
In the exhibit shown, the highlighted number next to the route type (Static) within the square brackets indicates the route preference, also known as the administrative distance. In Junos, the route preference is a value that determines the priority of the route source. Lower numbers indicate a higher priority when the routing table is being calculated. The route preference is used to select the best route when multiple paths to the same destination exist from different routing sources. The number 5 is unusually low for a static route by default, suggesting it has been manually configured to override other route types.
質問 # 61
Referring to the exhibit, which route(s) will be selected by Junos for packet forwarding?
正解：C
解説：
Junos OS selects routes based on the route preference (also known as administrative distance).
Static routes typically have a lower route preference than OSPF routes, meaning they are more preferred. Since the static route to 192.168.36.1/32 is shown with a preference of 5, it will be selected over the OSPF route for packet forwarding, assuming no other factors such as route filters or policies affect the routing decision.
質問 # 62
You are using the factory default configuration on a new Juniper router. You must successfully commit the configuration and activate the device. Which component must be configured before Junos OS will allow you to accomplish this task?
正解：C
解説：
When a Junos device is initialized for the first time or after a factory reset, it operates with a " factory-default
" configuration. This configuration contains the minimum settings necessary for the device to boot, but it lacks essential security parameters. The Junos OS kernel enforces a strict security mechanism that prevents any administrator from successfully executing a commit command until a root-level password has been defined.
Specifically, the root-authentication object must be configured under the [edit system] hierarchy. This requirement ensures that no Junos device is deployed into a production environment with an open, unauthenticated root account. If an administrator attempts to commit changes without this setting, the configuration parser will return a " missing mandatory statement " error and the commit process will fail.
While other settings-such as a system hostname, management IP address (on the fxp0 or me0 interfaces), or logical interface configurations-are critical for operational readiness, they are not strictly enforced by the system validation logic for the initial activation. Only the root-authentication (which can be a plain-text password or an encrypted key) is a hard prerequisite for transitioning the device from a default state to an active, running configuration.

質問 # 63
An administrator wants to set up a remote user authentication service for the many users that access a Juniper security device. In this scenario, what are two supported authentication protocols? (Choose two.)
正解：A、D
解説：
For managing high volumes of administrative users, Junos OS supports externalizing the authentication, authorization, and accounting (AAA) process. The two primary industry-standard protocols supported for this purpose are RADIUS (Remote Authentication Dial-In User Service) and TACACS+ (Terminal Access Controller Access-Control System Plus).
Using these protocols allows an architect to maintain a centralized user database on an external server (like Cisco ACS, FreeRADIUS, or Microsoft NPS) rather than configuring every individual user account locally on every Junos device. When a user attempts to log in via SSH or the console, the Junos device acts as a client, forwarding the credentials to the remote server. RADIUS is often preferred for its broad compatibility and efficiency, while TACACS+ is frequently chosen for its ability to separate authentication from authorization and its support for granular command-level accounting. SHA (Secure Hash Algorithm) is a cryptographic hash function used within these processes but is not an authentication protocol itself. Similarly, IPsec is a suite for securing IP communications (VPNs) and is unrelated to the administrative login AAA sequence.
