NEW QUESTION # 113
You are deploying an 802.1X solution and must determine what would happen if clients are unable to re-authenticate to the RADIUS server.
In this scenario, which configuration would provide access to the network if the supplicant is already authenticated?
- A. move
- B. sustain
- C. permit
- D. deny
Answer: B
Explanation:
Permit authentication, allowing traffic to flow from the end device through the interface as if the end device were successfully authenticated by the RADIUS server.
Deny authentication, preventing traffic from flowing from the end device through the interface.
This is the default.
Move the end device to a specified VLAN. (The VLAN must already exist on the router.) Sustain authenticated end devices that already have LAN access and deny unauthenticated end devices. If the RADIUS servers time out during reauthentication, previously authenticated end devices are reauthenticated and new users are denied LAN access.
NEW QUESTION # 114
Click the Exhibit.
You have just configured on an OSPF adjacency between two routers. After you commit the configuration, you notice that your adjacency is not up.
Referring to the exhibit, what would cause the problem?
- A. You must configure bfd on R2.
- B. You must configure lo on R2.
- C. You must configure hello and dead intervals on R1.
- D. You must configure on interface-type o n R2.
Answer: D
NEW QUESTION # 115
You are asked to configure 802.1X on your access ports to allow only a single device to authenticate.
In this scenario, which configuration would you use?
- A. MAC authentication mode
- B. single supplicant mode
- C. multiple supplicant mode
- D. single-secure supplicant mode
Answer: D
Explanation:
Single supplicant mode authenticates only the first end device that connects to an authenticator port. All other end devices connecting to the authenticator port after the first has connected successfully, whether they are 802.1X-enabled or not, are permitted access to the port without further authentication. If the first authenticated end device logs out, all other end devices are locked out until an end device authenticates. Single-secure supplicant mode authenticates only one end device to connect to an authenticator port. No other end device can connect to the authenticator port until the first logs out.
NEW QUESTION # 116

2?
- A. no-advertise
- B. no-export
- C. no-export-subconfed
- D. no-publish
Answer: B
Explanation:
no-advertise--Routes in this community name must not be advertised to other BGP peers.
no-export--Routes in this community must not be advertised outside a BGP confederation boundary. A stand alone autonomous system that is not part of a confederation should be considered a confederation itself.
no-export-subconfed--Routes in this community must not be advertised to external BGP peers, including peers in other members' ASs inside a BGP confederation.
NEW QUESTION # 121

- A. Router E receives Type 1 withdrawal messages from router C.
- B. Router E receives Type 2 withdrawal messages from router C.
- C. Router E receives Type 1 withdrawal messages from router D.
- D. Router E receives Type 2 withdrawal messages from router D.
Answer: C
NEW QUESTION # 122
You are using 802.1X authentication in your network to secure all ports. You have a printer that does not support 802.1X and you must ensure that traffic is allowed to and from this printer without authentication.
In this scenario, what will satisfy the requirement?
- A. MAC RADIUS
- B. static MAC bypass
- C. MACsec
- D. MAC filtering
Answer: B
Explanation:
For devices like printers that do not support 802.1X authentication, you can configure static MAC bypass. This allows traffic from devices with specific MAC addresses to bypass 802.1X authentication and gain network access directly.
References:
* From the Juniper documentation, you can implement static MAC bypass for devices that do not support
802.1X by configuring their MAC addresses to be statically permitted on the network.

NEW QUESTION # 123
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?
- A. captive portal
- B. 802.1X with multiple supplicant mode
- C. MAC RADIUS
- D. 802.1X with single-secure supplicant mode
Answer: C
Explanation:
https://www.juniper.net/documentation/us/en/software/junos/user-access/topics/topic-map/mac- radius-authentication-switching-devices.html You can configure MAC RADIUS authentication on an interface that also allows 802.1X authentication, or you can configure either authentication method alone.
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.
NEW QUESTION # 124
What allows non-Web enabled devices to access the network on a port configured for captive portal?
- A. Captive portal can be configured to only prompt for credentials when HTTP or HTTPS traffic is requested on a port to allow on-HTTP enabled devices access to the network.
- B. A MAC address white list can be configured on the switch to allow specific MAC addresses to bypass the captive portal process.
- C. LLDP can be used to query the type of device that is attempting to access the network, and predefined device types can be allowed to bypass the captive portal process.
- D. Authentication credentials for specific devices can be preconfigured on the switch for automatic authentication.
Answer: B
NEW QUESTION # 125
Referring to the exhibit, how is R1learning the route from R2? R2 has an export policy with external type 2 configured.
- A. R2 has interface ge-0/0/2 configured in another area under OSPFv3.
- B. R2 has an interface policy with external type 1 configured.
- C. R2 has interface ge-0/0 configured as a passive interface under OSPFv3.
- D. R2 has interface ge-0/0/2 configured as a passive interface under OSPFv3.
Answer: B
NEW QUESTION # 126
Which three MSTP parameters must match on all switches in the same MST region? (Choose three.)
- A. configuration name
- B. revision number
- C. bridge priority
- D. MSTI-to-VLAN mapping
- E. forwarding delay
Answer: A,B,D
Explanation:
To ensure proper functioning within an MST (Multiple Spanning Tree) region, the following parameters must match across all switches:
* Revision number:
* The revision number identifies the version of the MST configuration. All switches within the same MST region must have the same revision number to ensure consistency.
* MSTI-to-VLAN mapping:
* The MSTI (Multiple Spanning Tree Instance) to VLAN mapping must be identical on all switches. This mapping ensures that each VLAN is assigned to the correct spanning tree instance.
* Configuration name:
* The configuration name (or region name) must be the same across all switches. This name uniquely identifies the MST region and must be consistent to ensure switches recognize they are part of the same region.
References:
* The MSTP configuration requirements are detailed in Juniper network configuration guides and standards documents on MSTP.
