QUESTION 35
Which type of Virtual LAN (VLAN) created on a switch provides limited network access to a user who does not have a username and password configured on an Authentication, Authorization and Accounting (AAA) server?
A. A Guest VLAN
B. An IP protocol-based VLAN
C. A Virtual Private Network (VPN) VLAN
D. A VLAN on each port with limited network access
Correct Answer: A
QUESTION 36
Which three best describe how multicast packets are forwarded on a network? (Choose three.)
A. The destination address is used to select the forwarding path
B. The source sends packets to a group of destinations identified by the multicast address
C. Traffic is routed through the network along a single path from the source to the destination host
D. Multicast routers use a technique called Reverse Path Forwarding (RPF) to forward multicast traffic away from the source
E. Multicast routers determine which direction is upstream/downstream and send a copy of the multicast packet down each appropriate downstream path
Correct Answer: BDE
QUESTION 37
What is the result of the following two Virtual LAN (VLAN) Switch 8800 commands SWA-mstp-region] instance 0 vlan 201 202 and SWA-mstp-region] instance 1 vlan 211 212?
A. Creates four VLANs on the switch – VLAN 201, 202, 203 and 204
B. Instantly creates two VLANs that will be eliminated when the switch is rebooted
C. Configures the VLAN mapping table, creating multiple paths for VLAN 201, 202, 203 and 204
D. Configures the VLAN mapping table, creating two distinct paths – one for VLAN 201/202 and the other for VLAN 211/212
Correct Answer: D
QUESTION 38
What is the primary purpose of a Backup Designated Router (BDR) in an OSPF-based network?
A. It reduces the time of traffic disruption if the DR fails
B. It takes on the responsibility of polling other routers in the OSPF area
C. It sends Link State Advertisements (LSAs) to adjacent OSPF areas?routers
D. It provides load balancing when the DR reaches the user-defined utilization
Correct Answer: A
QUESTION 39
Click on the exhibit button. Why was IGMP snooping disabled on the Switch 5500 SWA VLAN Interface 1 (based on multicast commands shown in the exhibit)?
A. IGMP snooping and PIM-DM cannot be active on the same VLAN
B. IGMP snooping and PIM-DM cannot be active on the same switch
C. IGMP snooping and PIM-DM cannot be active on the same network
D. PIM-DM does all the functions of IGMP snooping and more, so IGMP snooping creates unnecessary overhead
Correct Answer: A QUESTION 40
What is a primary purpose of the master VRRP router on a network?
A. Is responsible for actually routing all traffic
B. Configures hosts to use the virtual default gateway
C. Provides Link State Advertisements to the other VRRP routers
D. Redirects traffic from the default gateway to the virtual gateway
Correct Answer: A QUESTION 41
Click on the exhibit button.
What must be done to enable load sharing on a subnet with multiple master VRRP routers (based on the VRRP network diagram shown in the exhibit)?
A. Configure each router with multiple IP addresses
B. Configure the subnet switches for STP – DISABLE
C. Configure each router with multiple VLANs to the default gateway
D. Configure the hosts in the same subnet to point to different default gateways
Correct Answer: D
QUESTION 42
Click on the exhibit button.
Which best describes the multicast network configuration (based on multicast commands and network diagram shown in the exhibit)?
A. SWB is responsible only for forwarding multicast packets for this network
B. SWB is responsible only for collecting and advertising the information about all multicast candidates? Rendezvous Points (RPs)
C. SWB is responsible for forwarding multicast packets for this network and for collecting and advertising the information about all multicast candidates Rendezvous Points (RPs)
D. SWB is responsible for forwarding multicast packets for VLAN2 only and for collecting and advertising the information about multicast candidates?Rendezvous Points (RPs) for VLAN2 only
Correct Answer: C QUESTION 43
Which two are reasons to use OSPF as your network routing protocol? (Choose two.)
A. OSPF scales to support larger networks by establishing multiple areas
B. Although RIP provides faster network convergence than OSPF, OSPF provides greater link reliability
C. OSPF uses less network bandwidth than RIP by using IP multicast to send advertisements
D. OSPF updates the network topology by forwarding the entire routing table, minimizing the need for multiple reconfigurations
E. OSPF only maintains the information on the best path or fastest link, reducing the size of the table and therefore network utilization
Correct Answer: AC QUESTION 44
