NEW QUESTION # 103
You are authenticating user devices connected to your ex Series switch. You have 802.1X and MAC RADIUS configured for all ports. A user is complaining about the time it takes to connect their non- 802.1X device on ge-0/0/15 using MAC RADIUS authentication.
Referring to the exhibit, what should be done to accelerate the authentication process?
- A. Change the supplicant mode to multiple on ge-0/0/15
- B. Change the 802.1X retry attempts value to 5 on ge-0/0/15
- C. Configure the restrict feature for MAC RADIUS on ge-0/0/15.

NEW QUESTION # 104
Click the Exhibit button.
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?
- A. Tunnel services have not been enabled on R1.
- B. All routers have not been configured with the same Auto-RP discovery group.
- C. A(*,G) tree has not been built yet.
- D. R5 has not received an IGMP report of 224.1.1.1.
Answer: A
Explanation:
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.

Referring to the exhibit, what must you configure to solve the problem?
You are asked to troubleshoot voice quality issues on your newly implement VoIP network. You notice that the voice packets are being dropped. You have verified that the packets are correctly marked for expedited forwarding queue.
Referring to the exhibit, what must you configure to solve the problem?
- A. You must configure a multifield classifier to put the VoIP traffic in the correct queue.
- B. You must configure a rewrite rule to ensure that the traffic is scheduled properly in the device.
- C. You must configure a scheduler to allocate bandwidth to the expedited forwarding queue.
- D. You must configure a policer to ensure that the queue is not being starved.
Answer: C
NEW QUESTION # 108
You have scheduled maintenance operations for one of the devices in your OSPF network.
Referring to the exhibit, which three statements are correct? (Choose three.)
- A. R1 does not send or receive transit traffic during the maintenance window even if no alternative paths exist to the given destination.
- B. R1 does not participate in OSPF routing.
- C. The metrics for all transit interfaces on R1 is set to the maximum value of 65,535.
- D. R1 participates in OSPF routing but does not send or receive transit traffic.
- E. Any traffic destined for networks that terminate on R1 will still be forwarded to R1.
Answer: C,D,E
Explanation:
- Configure the local routing device so that it appears to be overloaded. You might do this when you want the routing device to participate in OSPF routing, but do not want it to be used for transit traffic. - Traffic destined to directly attached interfaces continues to reach the routing device. - When configured, the transit interface metrics are set to the maximum value of 65535.

NEW QUESTION # 109
You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
In this scenario, which area is needed to accomplish this task?
- A. stub area
- B. totally stubby area
- C. non-to-stubby area
- D. totally non-to-stubby area
Answer: B
Explanation:
* Step 1: Identify the requirement.
* You need an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
* Step 2: Analyze the possible OSPF area types.
* Option A: Totally non-to-stubby area.
* Option B: Totally stubby area.
* Option C: Stub area.
* Option D: Non-to-stubby area.
* Step 3: Understand OSPF area types.
* Totally Stubby Area (Option B): Only allows Type 1 and Type 2 LSAs and blocks Type 3, 4, and 5 LSAs. It uses a default route to represent external routes.
* This fits the requirement of containing only intra-area routes.

NEW QUESTION # 110
You are troubleshooting a route problem in the topology shown in the exhibit. The 10.30.0 0/24 route is not reachable from the R3 router. What would cause this problem?
- A. R3 does not have an OSPF route for 10.30.0.0/24
- B. R3 does not have an established BGP session with R4.
- C. R3 does not have a route to the BGP next hop of 10.30.0.0/24

Answer: C
NEW QUESTION # 111
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. Disable the BPDU block function on the distribution switch.
- B. Configure the links between the access switches and the distribution switch as a trunk port.
- C. Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.
- D. Disable the BPDU block function on the access switches.
Answer: B
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.

Which action will be taken for route 12.233.45.5?
- A. It will be evaluated by the next policy.

Answer: B
NEW QUESTION # 115
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. Timers dictate when link state changes are propagated.
- B. When enabled, MVRP affects all interfaces.
- C. MVRP works with RSTP and VSTP.
- D. The forbidden mode does not register or declare VLANs.
Answer: D
Explanation:
When MVRP is enabled, the protocol manages VLAN registration dynamically. In forbidden mode, VLANs are neither registered nor declared on the interface, meaning it prevents VLANs from being learned or propagated.

2?
- A. no-publish
- B. no-export
- C. no-advertise
- D. no-export-subconfed
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 # 119
A customer on MSTI-2 was isolated due to a physical link outage on Switch 5's ge-0/0/32 interface.

NEW QUESTION # 120
You want to provide Layer 2 connectivity between campus sites using Ethernet switches through a metro Ethernet service provider who is using Q-in-Q tagging on their network.
Referring to the exhibit, what are two design considerations in this environment? (Choose two.)
- A. Each campus switch shown must have a C-Tag 300 configured.
- B. VXLAN could be implemented on your network across this service provider network.
- C. Each campus switch shown must have S-Tag 300 configured.
- D. L2PT is required on the SP network to support the spanning tree protocol.
Answer: B,D
Explanation:
* Understanding the Problem:
* The requirement is to provide Layer 2 connectivity between campus sites using Ethernet switches through a metro Ethernet service provider who is using Q-in-Q tagging.
* Design Considerations:
* VXLAN Implementation:
* VXLAN (Virtual Extensible LAN) can be used to extend Layer 2 networks over Layer 3 networks. It is often used to provide scalability and flexibility in modern data center networks. In this case, VXLAN could be used to encapsulate Layer 2 frames within UDP packets, allowing them to be transported over the service provider's network.
* S-Tag Configuration:
* Q-in-Q tagging, also known as 802.1ad, involves an outer tag (S-Tag) and an inner tag (C-Tag). The service provider network uses the S-Tag to identify and segregate customer traffic. Therefore, each campus switch must have the correct S-Tag (300 in this case) configured to ensure the service provider can correctly handle and route the traffic.
