- B . Layer 2
- C . Layer 3
- D . Layer 4
- E . Layer 5

A Layer 2 switch in the network has recently started broadcasting traffic out of every port and is impacting network performance. The engineering department determines that a MAC overflow attack is the cause.
Which two features can protect and mitigate the damage of the attacks? (Choose two.)
- A . Storm Control
- B . Port Security
- C . SPAN
- D . BPDU Filters
- E . IP Source Guard
- F . VACLs
Refer to the exhibit.
Based on the configuration, why are routers R1 and R2 not exchanging OSPF routes?
- A . The OSPF process numbers are different.
- B . There is no backbone area configured.
- C . The router IDs are different.
- D . OSPF is not enabled on the interfaces.
An engineer notices that many BGP peers utilize the same configuration parameters.
What can the engineer configure to simplify BGP neighbor statements and generate more efficient BGP peer updates?
- A . peer groups
- B . policy templates
- C . session templates
- D . peer address families
What is the correct state between two BGP peers that are neighbors?
- A . active
- B . operational
- C . established
- D . up
Refer to the exhibit.
A network engineer manually reconfigures the BGP configuration on newly upgraded router R1. However, the BGP neighbor relationship does not come up with the directly connected neighbor router.
What is causing the failure of the BGP neighbor relationship between routers R1 and R2?
- A . An incorrect neighbor IP address for router R2 is configured on router R1.
- B . An incorrect neighbor AS number is configured on router R1 for router R2.
- C . The wrong BGP authentication password is configured on router R1.
- D . Router R1 must configure the R2 loopback address as the neighbor IP address.
Which option is a primary requirement for the deployment of an IPv6-enabled network via the native method (dual-stack model) within the enterprise campus environment?
- A . hardware-based switching support for IPv6 forwarding on all campus switches
- B . restriction of IPv6-enabled devices to the core layer
- C . manual implementation of tunneling between IPv6-incompatible devices in an IPv4-over-IPv6
tunnel - D . disabling of multicast in the distribution layer prior to implementation of IPv6
