- Intermediate devices must have a route to the destination address of the traffic being tunneled.
- Intermediate devices must have a route to both the tunnel source address and the tunnel destination address.
- Intermediate devices must have a route to the tunnel destination address but do not require a route to the tunnel source address.
- Intermediate devices must have a route to the tunnel source address but do not require a route to the tunnel destination address.
Correct answer: C
Question 2
You have a conference room with an open network port that is used by employees to connect to the network. You are concerned about rogue switches being connected to this port.
Which two features should you enable on your switch to limit access to this port? (Choose two.)
- DHCP snooping
- dynamic ARP inspection
- MAC limiting
- 802.1X
Correct answer: AB
Question 3
Which statement is correct about IS-IS link state PDUs?
- They are used to maintain link-state database synchronization.
- They are used to establish adjacencies.
- They are used to build the link-state database.
- They are used to determine whether the neighbors are Level 1 or Level 2.
Correct answer: C
Question 4

- EBGP peers must be directly connected.
- EBGP connects peer devices in the same autonomous system.
- EBGP connects peer devices in two different autonomous systems.
- EBGP peers can be connected over a multihop connection.
Correct answer: CD
Question 5

- dynamic ARP inspection
- MACsec
- IP Source Guard
- MAC learning
Correct answer: AC
Question 6

- A lower system MAC address is preferred.
- A higher bridge priority is preferred.

Correct answer: C
Question 8
Which statement is correct about trunk ports?
- Trunk ports must have an IRB assigned to accept VLAN tagged traffic.
- By default, trunk ports accept only VLAN tagged traffic.
- By default, a trunk port can have only a single VLAN assigned.
- trunk ports must have an IRB assigned to accept untagged traffic.
Correct answer: B
Question 9
Your network is configured with dynamic ARP inspection (DAI) using the default parameters for all the DHCP and ARP related configurations. You just added a new device connected to a trunk port and configured it to obtain an IP address using DHCP.
Which two statements are correct in this scenario? (Choose two.)
- The DHCP server assigns the IP addressing information to the new device.
- DAI validates the ARP packets for the new device against the DHCP snooping database.
- The ARP request and response packets for the new device will bypass DAI.
- DHCP snooping adds the DHCP assigned IP address for the new device to its database.
Correct answer: AB
Question 10
Which two requirements must be satisfied before graceful restart will work? (Choose two.)
- a stable network topology
- a neighbor configured with BFD
- a neighbor configured with graceful restart
- a neighbor with an uptime greater than an hour
Correct answer: AC
