NEW QUESTION # 35
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. 802.1X with multiple supplicant mode
- B. 802.1X with single-secure supplicant mode
- C. captive portal
- D. MAC RADIUS
Answer: D
NEW QUESTION # 36
Which statement is true regarding LLDP advertisements?
- A. LLDP communicates VLAN information to VoIP devices
- B. LLDP communicates power requirements from PoE enabled devices
- C. LLDP communicates device information to neighbors
- D. LLDP communicates CoS values to VoIP devices
Answer: C
NEW QUESTION # 37
You are implementing 802.1x authentication in your Layer 2 network. Each user will have a computer and a phone and you must ensure that both device are authenticated individually. In this scenario, which supplicant mode should be used?
- A. Captive-portal
- B. Single-secure
- C. Single
- D. multiple
Answer: C
NEW QUESTION # 38
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. MVRP works with RSTP and VSTP.
- B. The forbidden mode does not register or declare VLANs.
- C. When enabled, MVRP affects all interfaces.
- D. Timers dictate when link state changes are propagated.
Answer: B
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/topic-map/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).
NEW QUESTION # 39
The connection between DC1 and DC2 is routed as shown in the exhibit.
In this scenario, which statement is correct?
- A. L3VPN must be enabled to advertise reachability.
- B. An IP prefix route provides encoding for intra-subnet forwarding.
- C. Type 2 and Type 5 routes will be exchanged between DC1 and DC2.
- D. The border devices must be able to perform Layer 3 routing and provide IRB functionality.
Answer: D
NEW QUESTION # 40
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?
- A. Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.
- B. Disable the BPDU block function on the access switches.
- C. Configure the links between the access switches and the distribution switch as a trunk port.
- D. Disable the BPDU block function on the distribution switch.
Answer: C
Explanation:
Access interfaces in an L2PT-enabled VLAN should not receive L2PT-tunneled PDUs. If an access interface does receive L2PT-tunneled PDUs, there might be a loop in the network, and the device will shut down the interface. https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/layer-2-protocol-tunneling.html
NEW QUESTION # 41
Referring to the exhibit, which two statements are correct? (Choose two.)
- A. If the total power consumption exceeds 90 watts, the ge-0/0/11 interface will continue to receive power.
- B. PoE is not enabled on the ge-0/0/0 interface.
- C. The maximum wattage that this switch can allocate to attached Ethernet devices is 100 watts.
- D. The ge-0/0/10 interface supports PoE+.
Answer: B,C
NEW QUESTION # 42
Which two statements about OSPF routing policies are correct? (Choose two.)
- A. By default, OSPF export policies accept network-summary LSAs.
- B. By default, OSPF export policies reject network-summary LSAs.
- C. By default, OSPF import policies accept network-summary LSAs.
- D. By default, OSPF import policies reject network-summary LSAs.
Answer: B,C
NEW QUESTION # 43
What are two similarities between OSPFv2 and OSPFv3? (Choose two.)
- A. protocol processing per link, not per subnet
- B. 32-bit router ID
- C. support for multiple instances per link
- D. virtual links
Answer: B,D
NEW QUESTION # 44
You recently committed a change to a router to reject OSPF routes sourced from area 10. However, you are still seeing area 10 routes in the routing table.
Referring to the exhibit, which statement is correct?
- A. The routes remain in the table until the device is rebooted.
- B. The OSPF protocol is first matched by find-ospf and accepted.
- C. The routes only timeout after 24 hours.
- D. The routes remain in the table until the routing daemon is restarted.
Answer: B
Explanation:
Once a route is accepted, no other terms in the routing policy are evaluated.
NEW QUESTION # 45
Your IPv4 multicast network uses different MX Series routers for the source DR and the PIM sparse-mode RP.
What is required before PIM register messages are exchanged between the DR and RP routers?
- A. Add a tunnel services PIC to the RP router.
- B. Configure PIM encapsulation on the DR and RP routers.
- C. Add an adaptive services PIC to the DR router.
- D. Enable tunnel services on the DR and RP routers.
Answer: D
NEW QUESTION # 46
