C. VRRP
D. PIM
E. HSRP
Answer: C,E
New Questions 10
Which two statements about Layer 3 access designs are correct? (Choose two.)
A. IP address space is difficult to manage.
B. Broadcast and fault domains are increased.
C. Convergence time is fractionally slower than STP.
D. Limits on clustering and NIC teaming are removed.
E. Fast uplink convergence is supported for failover and fallback.
Answer: A,E
New Questions 11
Which two statements correctly describe an IPS device? (Choose two.)
A. It resembles a Layer 2 bridge.
B. Traffic flow through the IPS resembles traffic flow through a Layer 3 router.
C. Inline interfaces which have no IP addresses cannot be detected.
D. Malicious packets that have been detected are allowed to pass through, but all subsequent traffic is blocked
E. Traffic arrives on the detection interface, is inspected, and exits via the same interface.
Answer: A,C
New Questions 12
Which option is the Cisco preferred, most versatile, and highest-performance way to deploy IPv6 in existing IPv4 environments?
A. dual stack
B. hybrid
C. service block
D. dual service
Answer: A
New Questions 13
Refer to the exhibit.
The Cisco Nexus 1000V in the VMware vSphere solution effectively creates an additional access layer in the virtualized data center network; which of the following 1000V characteristics can thedesigner take advantage of?
A. Offloads the STP requirement from the external Access layer switches
B. If upstream access switches do not support vPC or VSS the dual-homed ESX host traffic can still be distributed using virtual port channel host mode using subgroups automatically discovered through CDP
C. Allows transit traffic to be forwarded through the ESX host between VMNICs
D. Can be divided into multiple virtual device contexts for service integration, enhanced security, administrative boundaries, and flexibility of deployment
Answer: B
Explanation:
"Virtual Port Channel Host Mode Virtual Port Channel Host Mode (vPC-HM), shown in Figure 5-33 , allows a port channel from the Cisco Nexus 1000V to be terminated on two separate upstream switches, even if these switches do not support a clustering technology, such as vPC or VSS."

New Questions 18
The direction of the flow of multicast traffic is based on which protocol?
A. PIM
B. IGMP
C. underlying IGP
D. MSDP
Answer: C
Explanation: https://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ip_multicast/White_papers/mcst_ ovr.html
"Reverse Path Forwarding (RPF) PIM uses the unicast routing information to create a distribution tree along the reverse path from the receivers towards the source. The multicast routers then forward packets along the distribution tree from the source to the receivers. RPF is a key concept in multicast forwarding. It enables routers to correctly forward multicast traffic down the distribution tree. RPF makes use of the existing unicast routing table to determine the upstream and downstream neighbors. A router will forward a multicast packet only if it is received on the upstream interface. This RPF check helps to guarantee that the distribution tree will be loopfree."
