When configuring 802.1X authentication, what are three server fail fallback settings? (Choose three.)

log

sustain

permit

count

move

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/radius-server-configuration- ex-series-cli.html#id-configuring-radius-server-fail-fallback-cli-procedure
https://www.juniper.net/documentation/en_US/junos/topics/topic-map/radius-server-configuration- ex-series-cli.html 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 if the switch receives a RADIUS access-reject message. The configured VLAN name overrides any attributes sent by the server. (The VLAN must already exist on the switch.) 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.

Referring to the exhibit, the source is currently sending multicast traffic using group 224.1.1.1, which is being received by R1. R2 is not receiving PIM register messages.
What would be the cause of this problem?

Tunnel services have not been enabled on R1.

All routers have not been configured with the same Auto-RP discovery group.

R5 has not received an IGMP report of 224.1.1.1.

A(*,G) tree has not been built yet.

The multicast traffic being sent by the source must be encapsulated into a PIM register packet. If the tunneling services under the chassis stanza is not configured, a PE (PIM Encapsulation interface) will not be present in the multicast first hop router. Anyway long story short, tunneling services must be turned on or else you will not get PIM register messages sent to the RP.

There is a functioning OSPFv3 neighborship between Router-1 and Router-2 over the ge-0/0/1 link. However, the 172.100.100.0/24 and 172.101.101.100/24 routes are not being shared through OSPFv3.
Referring to the configuration shown in the exhibit, which two actions must you take to solve the problem? (Choose two.)

Add interface ge-0/0/1 under the IPv4 unicast realm for both routers.

Add the IPv6 family protocol under ge-0/0/2 for both routers.

Add the lo0 interface under OSPFv3 for both routers.

Add interface ge-0/0/2 under OSPFv3 for both routers.

新しい質問32

新しい質問33
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?

single supplicant mode

multiple supplicant mode

single-secure supplicant mode

MAC authentication mode

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.

Click the Exhibit.

The ping command shows that connectivity of the 200.0.1/24 network to the 200.0.200.0/24 network exists. You notice that all the ping test results from various devices on 200.0.1.0/24 follow the same path even through equal cost paths exist to the 200.0.200.0/24 network.
Referring to the exhibit, what is happening?

Load balancing needs to be enabled for equal cost pathing to work.

The rip-exp policy needs to be modified to advertise RIP routes

The RIP group must include the preference statement.

RIPv2 does not support load balancing static routes.

新しい質問 39
Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.
Which action would solve this problem?

Configure the links between the access switches and the distribution switch as a trunk port.

Disable the BPDU block function on the access switches.

Disable the BPDU block function on the distribution switch.

Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.

新しい質問 40
You have configured class mode power management on an EX4300 to provide PoE power to telephone and security camera equipment. You want to ensure that security camera power takes priority over telephone power.
Which two actions would solve this problem? (Choose two.)

Connect the security cameras to the lowest port numbers on the switch.

Set the power priority to high on ports connected to security cameras.

Set the maximum power settings on ports connected to security cameras.

Set the power priority to low on ports connected to security cameras.

https://www.juniper.net/documentation//en_US/junos/topics/concept/poe-overview.html#jd0e1522 Thus you must set interfaces that connect to critical powered devices, such as security cameras and emergency phones, to high priority. Among PoE interfaces that have the same assigned priority, power priority is determined by the port number, with lower-numbered ports having higher priority.

新しい質問41
You are deploying IP phones in your Layer 2 network and are asked to ensure that the switch sends VLAN and CoS information to the IP phones automatically.
In this scenario, which protocol should be used?

PoE

新しい質問 42
You are asked to enforce user authentication using a captive portal before users access the corporate network.
Which statement is correct in this scenario?

HTTPS is the default protocol for a captive portal.

A captive portal can be bypassed using an allowlist command containing a device’s IP address.

When enabled, a captive portal must be applied to each individual interface.

All Web browser requests are redirected to the captive portal until authentication is successful.
