Juniper Enterprise Routing and Switching, Professional (JNCIP-ENT) Sample Questions (Q98-Q103):

NEW QUESTION # 98
You are asked to enforce user authentication using a captive portal before users access the corporate network.
Which statement is correct in this scenario?

  • A. HTTPS is the default protocol for a captive portal.
  • B. When enabled, a captive portal must be applied to each individual interface.
  • C. A captive portal can be bypassed using an allowlist command containing a device's IP address.
  • D. All Web browser requests are redirected to the captive portal until authentication is successful.

Answer: D

Explanation:
You can set up captive portal authentication on your switch to redirect all Web browser requests to a login page that requires users to input a username and password before they are allowed access. Upon successful authentication, users are allowed access to the network and redirected to the original page requested.
Junos OS provides a customizable template for the captive portal window that allows you to easily design and modify the look of the captive portal login page. You can modify the design elements of the template to change the look of your captive portal login page and to add instructions or information to the page. You can also modify any of the design elements of a captive portal login page.
The first screen displayed before the captive login page requires the user to read the terms and conditions of use. By clicking the Agree button, the user can access the captive portal login page.

NEW QUESTION # 99
Your network is multihomed to two ISPs. The BGP sessions are established; however, the ISP peers are not receiving any routes.
Which two statements are correct about troubleshooting your configuration? (Choose two.)

  • A. Verify the export policies on your router.
  • B. Verify that the BGP routes are active in your routing table.
  • C. Verify the import policies on your router.
  • D. Verity that the multihop settings are configured on your router.

Answer: A,B

Explanation:
To troubleshoot why ISP peers are not receiving any routes in a multihomed BGP setup, the following steps are essential:
* Verify Active BGP Routes: Ensure that the BGP routes are active in the routing table. Only active routes can be advertised to BGP peers.
shell
Copy code
show route protocol bgp
* Verify Export Policies: Check the export policies configured on your router. The export policies determine which routes are advertised to BGP peers. If these policies are incorrectly configured or missing, routes will not be advertised.
shell
Copy code
show configuration policy-options policy-statement <policy-name>
show configuration protocols bgp group <group-name> export

NEW QUESTION # 100
A BGP network has been designed to provide resiliency and redundancy to a multihomed customer network.
Which two statements are correct in this scenario? (Choose two.)

  • A. The ttl statement must be configured to accommodate peering to a loopback address of a directly connected peer.
  • B. Both the next hops will be used to forward traffic to R2.
  • C. The TTL value of 1 is set to limit the scope of the EBGP session.
  • D. A routing policy will be required to forward traffic to both next hops.

Answer: C,D

Explanation:
B - because only one next hop in forwarding table C- becuse TTL=1 limiting bgp connection to be established only over loopbacks interface
https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/topic-map/multihop-sessions.html Use the multihop statement to alter the default use of the neighbor's physical address. In addition, you can also specify a time-to-live (TTL) value in the BGP packets to control how far they propagate. We use a TTL value of 1 to ensure that the session cannot be established across any other backdoor links in the network.


NEW QUESTION # 101
You must provide network connectivity to hosts that fail authentication.
In this scenario, what would be used in a network secured with 802.1X to satisfy this requirement?

  • A. Configure the port as a spanning tree edge port.
  • B. Configure the native-vlan-id parameter on the port.
  • C. Configure a secondary IP address on the port for unauthenticated hosts.
  • D. Use the server-reject-vlan command to specify a guest VLAN.

Answer: D

Explanation:
* Understanding 802.1X Authentication:
* 802.1X is a network access control protocol that restricts access until the device or user is authenticated.
* Guest VLAN Configuration:
* When hosts fail authentication, they need to be placed in a separate VLAN to provide limited network access.
* server-reject-vlan Command:
* This command configures a VLAN for unauthenticated devices.
* Ensures that devices that fail authentication are placed in a designated guest VLAN.
* Configuration Example:
shell
Copy code
set protocols dot1x authenticator interface ge-0/0/1.0 server-reject-vlan guest-vlan References:

NEW QUESTION # 102
In OSPF, how does a router ensure that LSAs advertised to a neighboring router are received?

  • A. LSAs are sent over a TCP connection.
  • B. LSA flooding guarantees that all routers will receive them successfully.
  • C. LSAs are acknowledged by the neighboring router.
  • D. LSAs are advertised with an acknowledgement bit.

Answer: C

Explanation:
* OSPF Protocol Basics:
* OSPF (Open Shortest Path First) is a link-state routing protocol.
* Routers exchange LSAs (Link-State Advertisements) to share topology information.
* LSA Acknowledgment Mechanism:
* OSPF uses a reliable mechanism to ensure LSAs are received.
* When a router sends an LSA to a neighbor, it expects an acknowledgment (ACK).
* If an ACK is not received within a certain period, the router will retransmit the LSA.
* Acknowledgment Process:
* LSAs are sent over OSPF's reliable transport, which ensures delivery through acknowledgments.
* This mechanism helps to maintain consistent and up-to-date topology databases across routers.
