Juniper JN0-649 Sample Questions – Free Practice Test & Real Exam Prep
Question #1
What are two similarities between OSPFv2 and OSPFv3? (Choose two.)
A. virtual links
B. support for multiple instances per link
C. 32-bit router ID
D. protocol processing per link, not per sub net
Answer: A,C
Question #2
You are deploying new Juniper EX Series switches in a network that currently is
using Cisco’s Per-VLAN spanning tree plus (PVST+) and you must provide compatibility
with this environment.
Which spanning tree protocol do you deploy in this scenario?
A. STP
B. MSTP
C. VSTP
D. RSTP
Answer: B
Question #3
You are asked to establish interface level authentication for users connecting to your
network. You must ensure that only corporate devices, identified by MAC addresses, are
allowed to connect and authenticate. Authentication must be handled by a centralized
server to increase scalability.
Which authentication method would satisfy this requirement?
If both MAC RADIUS and 802.1X authentication are enabled on the interface, the switch
first sends the host three EAPoL requests to the host. If there is no response from the host,
the switch sends the host’s MAC address to the RADIUS server to check whether it is a
permitted MAC address. If the MAC address is configured as permitted on the RADIUS
server, the RADIUS server sends a message to the switch that the MAC address is a
permitted address, and the switch opens LAN access to the nonresponsive host on the
interface to which it is connected.
Question #4
When using wide metrics, which two statements about route advertisement between IS-IS
levels are correct?(Choose two.)
A. Level 1 and Level 2 routers do not advertise Level 2 routes into the Level 1 area by
default.
B. Level 1 routes are advertised to Level 2 routers by default.
C. If wide-metrics-only is configured, Level 1 routes are not advertised to Level 2 routers by
default.
D. Level 1 routes advertised as external routes into Level 1 are not advertised to any Level
2 routers by default.
Answer: A,C
Question #5
Which two statements are correct about the deployment of EVPN-VXLAN on QFX Series
devices?(Choose two.)
A. Type 1 route advertisements always have the single-active flag set to 1.
B. Junos OS supports underlay replication for BUM traffic forwarding.
C. Junos OS supports ingress replication for BUM traffic forwarding.
D. Type 1 route advertisements always have thesingle-active flag set to 0.
Answer: C,D
Explanation: BUM Traffic Forwarding
Junos devices that use MPLS encapsulation for EVPNs can only use ingress replication at
this time.
Ingress replication means, to flood traffic to remote PE routers, the traffic has to be
replicated, once for each remote PE router The EVPN label for this BUM traffic is learned per PE router from the route type 3, inclusive
multicast Ethernet tag route.
This table shows the format of the inclusive multicast Ethernet tag route. All-Active Redundancy (4)
This diagram shows the format of the type 1 route, A-D route per ES. The split horizon
label is advertised as part of an extended community attached to the type 1 route. The split
horizon label is also called the ESI label. The extended community also indicates what type
of redundancy mode is used for this given ESI: single-active represented by binary 1 or
active-active represented by binary 0.
Question #6
You enable the Multiple VLAN Registration Protocol (MVRP) to automate the creation and
management of virtual LANs. Which statement is correct in this scenario?
A. The forbidden mode does not register or declare VLANs.
B. When enabled, MVRP affects all interfaces.
C. Timers dictate when link state changes are propagated.
D. MVRP works with RSTP and VSTP.
Answer: A
Explanation: The forbidden mode does not register or declare VLANs. You can change
the registration mode of a specific interface to forbidden. An interface in forbidden
registration mode does not participate in MVRP even if MVRP is enabled on the switch.
https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topicmap/mvrp.html
MVRP is disabled by default on the switches and, when enabled, affects only trunk
interfaces. Once you enable MVRP, all VLAN interfaces on the switch belong to MVRP (the
default normal registration mode) and those interfaces accept PDU messages and send
their own PDU messages. forbidden—The interface does not register or declare VLANS
(except statically configured VLANs).
Question #7
You are asked to implement fault tolerant RPs in your multicast network.
Which two solutions would accomplish this behavior? (Choose two.)
A. Use BFD with statically defined RPs.
B. Use MSDP with statically defined RPs.
C. Use any cast PIM with statically defined RPs.
D. Use IGMPv3 with statically defined RPs.
Answer: B,C
Question #8
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 native-vlan-id parameter on the port.
B. Use the server-reject-vlan command to specify a guest VLAN.
C. Configure a secondary IP address on the port for unauthenticated hosts.
D. Configure the port as a spanning tree edge port.
Answer: B
Explanation: For a device configured for 802.1X authentication, specify that when the
device receives an Extensible Authentication Protocol Over LAN (EAPoL) Access-Reject
message during the authentication process between the device and the RADIUS
authentication server, supplicants attempting to access the LAN are granted access and
moved to a specific bridge domain or VLAN. Any bridge domain, VLAN name or VLAN ID
sent by a RADIUS server as part of the EAPoL Access-Reject message is ignored.
Question #9
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. A captive portal can be bypassed using an allow list command containing a device’s IP
address.
C. When enabled, a captive portal must be applied to each individual interface.
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.https://www.juniper.net/documentation/us/en/software/junos/user-access/topics/topicmap/user-authenti...
Question #10
You are implementing the route summarization feature of OSPF.
Which two results do you achieve in this scenario? (Choose two.)
A. It helps in migrating to future multi-area OSPF network designs.
B. It reduced the routing table size, enabling devices to store and process less information.
C. It reduces the impact of topology changes on a device.
D. It provides optimal routing in the network.
Answer: B,C
Explanation: OSPF inter-area route summarization reduces the routing information
exchanged between areas and the size of routing tables, and improves routing
performance. OSPF inter-area route summarization enables an ABR to summarize
contiguous networks into a single network and advertise the network to other areas.
