Question 41
Refer to the exhibit.An engineer must design a WAN solution so that ISP-1 is always preferred over ISP-2. The path via ISP-2 is considered as a backup and must be used only when the path to ISP-1 is down. Which solution must the engineer choose?

R1: - Routes advertised to ISP-1: 0x AS-path prepend - Routes received from ISP-1: HIGH local-preference - Routes advertised to R2: no action - Routes received from R2: community NO-EXPORT R2: - Routes advertised to ISP-2:5x AS-path prepend - Routes received from ISP-2: LOW local-preference - Routes advertised to R1: community NO-ADVERTISE - Routes received from R1: no action
B. R1: - Routes advertised to ISP-1: 0x AS-path prepend - Routes received from ISP-1: HIGH local-preference - Routes advertised to R2: community NO-EXPORT - Routes received from R2: no action R2: - Routes advertised to ISP-2: 5x AS-path prepend - Routes received from ISP-2: LOW local-preference - Routes advertised to R1: no action - Routes received from R1: no action
C. R1: - Routes advertised to ISP-1: 0x AS-path prepend - Routes received from ISP-1: LOW local-preference - Routes advertised to R2: community NO-ADVERTISE - Routes received from R2: no action R2: - Routes advertised to ISP-2: 5x AS-path prepend - Routes received from ISP-2: HIGH local-preference - Routes advertised to R1: no action - Routes received from R1: community NO-ADVERTISE
D. R1: - Routes advertised to ISP-1: 5x AS-path prepend - Routes received from ISP-1: LOW local-preference - Routes advertised to R2: community NO-ADVERTISE - Routes received from R2: no action R2: - Routes advertised to ISP-2: 0x AS-path prepend - Routes received from ISP-2: HIGH local-preference - Routes advertised to R1: community NO-EXPORT - Routes received from R1: no action
Question 42
Which feature must be incorporated into the campus LAN design to enable Wake on LAN?
A. dynamic ARP Inspection Snooping on layer 2 devices
B. directed broadcasts on layer 3 devices Most Voted
C. proxy ARP on layer 3 devices
D. DHCP Snooping on layer 2 devices
Question 43
Refer to the exhibit. An engineer must optimize the traffic flow of the network. Which change provides a more efficient design between the access layer and the distribution layer?
A. Add a link between access switch A and access switch B
B. Reconfigure the distribution switch A to become the HSRP Active
C. Change the link between distribution switch A and distribution switch B to be a routed link
D. Create an EtherChannel link between distribution switch A and distribution switch B
Question 44
Which first hop redundancy protocol ensures that load balancing occurs over multiple routers using a single virtual IP address and multiple virtual MAC addresses?
A. GLBP
B. IRDP
C. VRRP
D. HSRP
Question 45
A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link. Which approach achieves this goal and does not impact router CPU utilization?
A. Utilize BFD and tune the multiplier to 50
B. Lower the BGP hello interval
C. Decrease the BGP keepalive timer
D. Utilize BFD and keep the default BGP timers
Question 46
An engineer is designing an enterprise campus network. The LAN infrastructure consists of switches from multiple vendors, and Spanning Tree must be used as aLayer 2 loop prevention mechanism. All configured VLANs must be grouped in two STP instances. Which standards-based Spanning Tree technology supports this design solution?
A. MSTP
B. RSTP
C. Rapid PVST
D. STP
Question 47
A network engineer must segregate three interconnected campus networks using IS-IS routing. A two-layer hierarchy must be used to support large routing domains and to avoid more specific routes from each campus network being advertised to other campus network routers automatically. Which two actions does the engineer take to accomplish this segregation? (Choose two.)
A. Designate two IS-IS routers as BDR routers at the edge of each campus, and configure one BDR for all Level 1 routers and one BDR for all Level 2 routers.
B. Designate two IS-IS routers from each campus to act as Level 1/Level 2 backbone routers at the edge of each campus network.
C. Assign the same IS-IS NET value for each campus, and configure internal campus routers with Level 1/Level 2 routing.
D. Utilize different MTU values for each campus network segment. Level 2 backbone routers must utilize a larger MTU size of 9216.
E. Assign a unique IS-IS NET value for each campus, and configure internal campus routers with Level 1 routing.
Question 48
Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?
A. DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.
B. A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.
C. DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD-Access fabric with anycast gateway.
D. DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discover originated.
Question 49
Which function are fabric intermediate nodes responsible for in an SD-Access Architecture?
A. mapping EIDs to RLOCs
B. encapsulating user traffic in a VXLAN header including the SGT
C. registering new endpoints in the HTDB
D. transporting IP packets between edge nodes and border nodes
Question 50
How do endpoints inside an SD-Access network reach resources outside the fabric?
A. a VRF fusion router is used to map resources in one VN to another VN
B. Fabric borders use VRFs to map VNs to VRFs
C. SD-Access transit links are used to transport encapsulated traffic from one fabric to another
D. A fabric edge is used to de-encapsulate VXLAN traffic to normal IP traffic then transported over the outside network
