- B. The current device was allowed after authentication attempts to the RADIUS server failed
- C. The current device is authenticated using MAC RADIUS

Answer: B
NEW QUESTION # 52
You are using 802.1X in your access network consisting of EX Series switches. You recently had a failure with your RADIUS server which resulted in authenticating client devices being denied access to the network. You want to change this behavior so that authenticating clients are directed to a remediation VLAN. Which RADIUS server failback setting satisfies this requirement?
- A. sustain
- B. move
- C. deny
- D. permit
Answer: B
Explanation:
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 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.
NEW QUESTION # 53
You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically negotiate the power requirements for the new connection with the EX Series switches. In this scenario, which protocol should be used to enable this behavior?

- C. CDP
- D. LLDP
Answer: B

NEW QUESTION # 56
Which two multicast listener registration protocols are supported in the Junos operating system? (Choose two.)
- A. MLD
- B. DVMRP
- C. PIM
- D. IGMP
Answer: A,D
Explanation:
* Understanding Multicast Listener Registration Protocols:
* Multicast listener registration protocols are used to manage multicast group memberships on a network.
* They allow devices to join or leave multicast groups dynamically.
* Protocols Supported by Junos:
* MLD (Multicast Listener Discovery):
* Used for IPv6 multicast group management. It is the IPv6 equivalent of IGMP.
* MLD allows routers to discover multicast listeners on a network.
* IGMP (Internet Group Management Protocol):
* Used for IPv4 multicast group management.
* IGMP enables hosts to join and leave multicast groups and allows routers to manage multicast group memberships.
* Verification and Configuration in Junos:
* MLD and IGMP are supported on Juniper devices running the Junos operating system.
* Configuration examples:
* IGMP:
shell
Copy code
set protocols igmp interface ge-0/0/1.0
* MLD:
shell
Copy code
set protocols mld interface ge-0/0/1.0

NEW QUESTION # 62
Referring to the exhibit, anycast RP is implemented to ensure multicast service availability. The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information.
In this scenario, what are two methods to receive the active source information on R2? (Choose two.)
- A. Configure an RP set in PIM on R1, allowing R1 to forward PIM register messages to R2 and R3 in the set.
- B. Configure an MSDP protocol between R2 and R3.
- C. Configure an RP set in PIM on R2 and R3, allowing the RPs to forward PIM register messages to the other RPs in the set.
- D. Configure an MSDP protocol between R1 and R2.
Answer: B,C
Explanation:
* Anycast RP uses Multicast Source Discovery Protocol (MSDP) to discover and maintain a consistent view of the active sources. nclude the anycast-pim statement to configure anycast RP without MSDP (for example, if IPv6 is used for multicasting). The other RP routers that share the same IP address are configured using the rp-set statement.
