NEW QUESTION # 37
Exhibit
Referring to the exhibit, which two statements are correct? (Choose two.)
- A. Prefixes in Level 2 will be redistributed to Level 1.
- B. Prefixes in Level 1 will not be redistributed to Level 2.
- C. Prefixes in Level 1 will be redistributed to Level 2.
- D. Prefixes in Level 2 will be not redistributed to Level 1.
Answer: C,D
Explanation:
By default, IS-IS protocol leaks routing information from a Level 1 area to a Level 2 area. However, to leak routing information from a Level 2 area to a Level 1 area, an export policy must be explicitly configured.
NEW QUESTION # 38
Which two statements ate correct about the BGP next-hop attribute value? (Choose two.)
- A. By default, the next-hop value is changed across EBGP links.
- B. By default, the next-hop value is not changed across EBGP links.
- C. By default, the next-hop value is not changed across IBGP links.
- D. By default, the next-hop value is changed across IBGP links.
Answer: A,C
Explanation:
By default, the router that originally sourced the route into BGP places its peer address into the attribute field.
The next-hop value is then typically changed when the route is transmitted across external gGP (EBGP) links.
Internal BGP (IBGP) peers do not alter the next-hop value between themselves.
B). By default, the next-hop value is changed when a route is passed from an EBGP peer to another EBGP peer.C. By default, the next-hop value is retained when a route is advertised across IBGP links.References:

NEW QUESTION # 48
Exhibit
Referring to the exhibit, which statement is true about VRRP?
- A. The routers should use different virtual IP addresses for VRRP to function correctly.
- B. VRRP communication between the two devices is not functioning correctly.
- C. VRRP Is functioning normally in active/active mode.
- D. Both routers are in the same state because they have the same VRRP priority.
Answer: C
Explanation:
The exhibit shows theshow vrrp summaryoutput from two routers, with both routers listing the state of their VRRP group asmaster. VRRP allows for multiple routers to share a virtual IP address and a virtual MAC address, but usually, only one router is the master at any given time while others are in backup state. However, in some configurations, VRRP can operate in an active/active mode where multiple routers handle traffic simultaneously for load sharing. Since both routers show the state asmasterand there is no evidence of misconfiguration in the virtual IP addresses or priority, it indicates that VRRP is likely functioning in an active/active setup.

NEW QUESTION # 54
Which two statements are correct about segment routing? (Choose two.)
- A. Segment routing adjacencies require very little resources to maintain.
- B. Label assignments can be advertised through OSPF updates.
- C. There are no segment routing adjacencies to maintain.
- D. Label assignments can be advertised through LDP updates.
Answer: A,B
Explanation:
Segment routing is a source routing paradigm that allows a source router to define the path that a packet will take through the network by assigning an ordered list of segments-identifiers that specify a forwarding path for the packet through the network. Segment Routing can be implemented over an MPLS architecture or with IPv6 (SRv6).
A). Segment routing does not require a full mesh of adjacencies or state per transit path in the network, which is often the case with conventional MPLS signaling protocols like RSVP-TE. It leverages the existing IGP topology for forwarding without the need to maintain a state for each LSP (Label Switched Path), hence requiring very little resources to maintain.
B). In segment routing, labels (or segments) are distributed via IGP routing protocols like OSPF or IS-IS with extensions to carry segment routing information. These protocols are enhanced with Segment Routing extensions to distribute labels. For example, OSPFv2 is extended with Segment Routing extensions defined in RFC 8665.
C). This statement is not entirely correct. While it is true that segment routing does not require the maintenance of a state for each path (LSP), the concept of "segment routing adjacencies" is a mischaracterization. Segment routing leverages the existing adjacencies formed by the underlying IGP.
D). Label assignments in segment routing are not advertised through LDP (Label Distribution Protocol) updates. Segment routing does away with LDP and instead uses IGP extensions to distribute labels.
